Huawei is strong and empowered, and the new M7 in the world will definitely exceed 120,000.

In this era, the new energy automobile industry is facing a great change in intelligence, and in this change, the new M7 is undoubtedly a bright star to lead the trend. With the rapid development of science and technology, intelligence is not only a trend, but also an inevitable choice for travel in the new era. With its unique "three-intelligence ceiling" hard-core technical strength, the new M7 has successfully raised the benchmark of intelligent travel to a new height. From intelligent driving to intelligent cockpit to intelligent safety, it has successfully attracted everyone’s attention. On December 26th, it was mentioned in the press conference on the whole scene of the M9 and Huawei that the cumulative number of new M7 in the world has exceeded 120,000, among which more than 60% of users choose the smart driving version, and the monthly delivery capacity will reach 30,000 from January next year.

The top choice in the field of intelligent driving, Huawei ADS 2.0 breaks the imagination of intelligent driving.

For the current users, intelligence is a crucial factor when choosing a car, and the new M7 in Wenjie is equipped with HUAWEI ADS 2.0 advanced intelligent driving system, which not only subverts the traditional concept of intelligent driving, but also brings excellent driving pleasure and travel convenience to users.

When the vehicle is running, HUAWEI ADS 2.0 enables M7 to perceive the surrounding environment in real time through the precise integration of 27 sensing hardware, and realize the accurate perception and recognition of the whole scene and all weather. This not only improves the safety of driving, but also makes users feel a more intimate connection with the vehicle.

The power of intelligence is not only manifested in the driving process, but also throughout the entire travel experience. The NCA intelligent driving system of the new M7 can identify all kinds of situations around the vehicle more accurately through various sensors such as laser radar, making travel safer and easier. In addition, the new M7 also introduces excellent intelligent parking capability, which enables vehicles to easily identify various parking spaces and realize automatic parking through innovative technical means, so that users are no longer subject to parking difficulties when driving in cities.

A smart cockpit that breaks through the boundary, Smart Cockpit 3.0 makes travel more convenient.

The smart cockpit of the new M7 is also one of the highlights that will lead to future travel. HarmonyOS Intelligent Cockpit 3.0 brings a creative and interesting interactive space for users. First of all, many people admire the fluency of the HarmonyOS car machine system, which makes users feel like they are in a virtual world full of science and technology and interest during driving, especially with the blessing of Xiaoyi’s intelligent assistant, which makes the intelligent interactive experience more advanced and allows drivers to interact with vehicles more conveniently, which not only improves the convenience of operation, but also brings more entertainment for drivers.

The emergence of HUAWEI MagLink? smart car screen system is also a bright spot. It has reached the level of Huawei’s flat panel, realizing the smoothness of multi-screen interaction, making the car a flexible and ever-changing space, allowing drivers to have more possibilities in the car.

It is worth mentioning that HarmonyOS Intelligent Cockpit 3.0 can realize a series of functions, such as offline map voice navigation, which improves the practicality to a new height and makes travel more convenient. Through the support, the car has also achieved a smooth conversion with various applications in Huawei mobile phones. Whether you are chasing a drama or playing a game, users can connect seamlessly after getting on the bus and enjoy a more coherent and intelligent interactive experience.

Intelligent safety leads, omni-directional anti-collision safety guarantees lead to new standards of travel safety.

In terms of travel safety, the new M7 is also very careful. The world’s first omni-directional anti-collision system of HUAWEI ADS 2.0 installed in the car can provide users with all-round safety protection. With the help of multi-sensor fusion sensing capability based on lidar, HUAWEI ADS 2.0 has achieved omni-directional anti-collision capability in forward, lateral and backward directions, providing an efficient and accurate collision warning and response mechanism for vehicles. The system can not only identify common obstacles, but also identify road boundaries, so that vehicles can adapt to the changing driving environment more intelligently.

It is particularly noteworthy that in the AEB active safety evaluation of Autolab, the new M7 in the world won all kinds of active safety evaluation champions with HUAWEI ADS 2.0, which shows that its safety performance is high, and it can also stop in time when it participates in the evaluation at 90km/h at night, which also gives feedback on the strength of the new M7 in the world.

At the M9 and Huawei Panorama Conference, it was mentioned that the brand-new super smart factory, with more than 1,000 intelligent devices, 100% automation and integrated die casting process, has the highest production efficiency in the world and a new car is rolled off the assembly line every 30 seconds. With its excellent strength, Wenjie is becoming a leader in the new energy large SUV market, and its "three-intelligence ceiling" strength has been confirmed in many ways. This is not only a car, but also a future journey of intelligence, safety and innovation. I believe that in the future, the new M7 will be able to win the favor of more consumers.

Chinese Express’s first domestic mass production L4 fully independent parking service successfully landed and put into trial production.

  Economic Daily-China Economic Net September 14th Recently, Chinese Express announced that the L4 fully autonomous parking service system (AVP) has been developed in Shanghai, and it has been tested and put into trial production on the high-tech HIX production vehicle. This is also the first domestic L4 fully autonomous parking service system based on vehicle-road coordination on mass-produced electric vehicles, which indicates that the research and development of intelligent electric vehicles in China is in a leading position in the world in the advanced technology field of autonomous driving. Ding Lei, Chairman of the Board of Directors, said that Chinese Express always starts from the dimension of users’ travel, stands at the forefront of autonomous driving, takes users’ safety as the premise, comprehensively improves the overall efficiency of traffic travel, and truly promotes the mass production application of autonomous driving and vehicle-road coordination technology in a wider range.

  AVP(Automated Valet Parking) is an L4 high-order automatic driving system based on vehicle-road cooperative development. Roadside sensing devices such as laser radar and communication and calculation devices are pre-built in the parking area to realize the identification and tracking of vehicle position and surrounding obstacles, and the dispatching information, vehicle positioning, obstacles and other information are sent to the vehicle through the cooperation of 5G vehicles, and the vehicle automatically drives into the parking space. The owner got off at the parking area, and the vehicle drove into the parking lot and parked in the parking space. The vehicle can also be started through the APP, automatically driving out of the parking space and driving to the location specified by the user.

  AVP can overcome the difficulties that bicycle intelligence is difficult to solve, such as no GPS positioning signal in the parking lot, too many turning shades, and large sensor blind area, so that HIX has the most reliable fully autonomous parking function at present. It is reported that HiPhi X, the first intelligent electric vehicle owned by Chinese Express, which will be listed at Beijing Auto Show, will be equipped with this technology, and it will become the first intelligent electric vehicle in China to realize L4 autonomous parking in mass production, creating a new era for the development of intelligent electric vehicles in China.

  In addition to AVP, the HiPhi X autopilot system equipped with HiPhi Pilot is the only dual redundancy system equipped according to the principle of aircraft safety design. The vehicle can start, stop, turn and walk in the full speed range of 0-130km/h, so that the feet can be separated, the hands can be put down and the eyes can be moved; Through the joint action of 24 sensors (including intelligent forward-looking camera, panoramic camera, millimeter-wave radar, ultrasonic radar, DMS camera for driver status detection, etc.) and high-precision maps, the L3-level automatic driving level of bicycles is realized, and it is also the first mass-produced vehicle in China to reach L3-level at present.

  In 2019, Chinese Express opened the world’s first intelligent road for coordinated autonomous driving in Yancheng, Jiangsu Province, and opened the "Smart City" demonstration project for the integration of 5G roads and cities in Zhangjiang Artificial Intelligence Island. The realization of autonomous parking service is another successful landing and application of roadside perception, cloud scheduling and vehicle control put forward by Chinese Express in the field of automatic driving based on the "three intelligences" strategy of smart cars, smart transportation and smart cities, and it will be extended to smart travel fields such as smart parking lots and smart highways in the future.

Who is tomoji? Where did you come from and where did you go?

After attending the Zhiji auto conference, I posted some pictures of new cars on social media and immediately received a user comment: "Buying a car these days is the same as buying a mobile phone." What this user actually means is that the current car is updated quickly and dazzled.

 

 

Through this topic, we go deep into the perspective of industry. What is happening in the automobile industry is also very similar to the development path of smart phones. In addition to the historic event that Apple defeated Europeans, China’s mobile phone industry has also become the most important pole in the world, and its brand image and core technology have made rapid progress. Huawei even made its own various core chips. Today, it used to be considered as an insurmountable operating system, and Huawei also used the HarmonyOS operating system to announce that we had turned over this mountain.

 

Under the background that cars are becoming smarter and more electrified, the whole industry is similar to the smart phone industry in the past, but the wheelbase of time is not long enough. Maybe looking back 10 years later, this feeling will be more profound.


Let’s focus on the present. The number of new automobile brands in China is unique in the world, and those traditional automobile manufacturers are also trying to build higher-end new brands, polish more eye-catching new products and start the horn of having more core technologies through this historic opportunity of change. Last month’s case was Dongfeng Motor, which launched Lantu, and this month’s case was SAIC, which pushed Zhiji to the stage.

 

Who is tomoji?

 

 

Strictly speaking, Zhiji is not unique to SAIC, but a new brand jointly created by SAIC, Alibaba and Zhangjiang Hi-Tech. As a newly established brand, you may still be unfamiliar with it.

 

Zhiji, which reads "self". Why take such a name? According to the official, Zhiji is taken from The Book of Changes, "Knowing everything is around, but Dao Ji is under the world", aiming at understanding everything with wisdom, diligently exploring, defining, creating and realizing the smart travel driven by the times and needed by users.

 

We can simply understand that intelligence represents intelligence; Represent oneself, alsonamelyUsers.If you read their introductions in the official media of Zhiji, you will definitely see what cars should look like in the intelligent age."This sentence.In addition to the three major shareholders, 4.9% of Zhiji’s shares will be built into a user rights platform.Therefore, Zhiji is a condensation of the two visions expressed by this brand.

 

 

Zhiji’s English brand name is "IM", which is the same as the Chinese name. Besides, purely for fun, the name IM is attractive, at least it will make people think of the iPhone.

 

The user rights platform is heavy enough, so it goes without saying what users participate in product design.

 

Where is the intelligence?

 

Is Zhiji really smart? Zhiji’s speed is fast enough. On the 13th, Zhiji has released two new cars, a car and an SUV, all of which have not been officially named, and they have no names when they are unveiled. Presumably, the naming of new cars that are still brewing inside must also have strong characteristics. Cars will be accepted during the Shanghai Auto Show in April, listed at the end of the year, and delivered to users in 2022. The progress of SUV is a little late, but it will also be listed in 2022.

 

Through specific models, let’s look at the intelligence of Zhiji.

 

 

Zhiji’s car is equipped with intelligent lighting system, which is composed of 2.6 million pixels DLP and 5,000 LED ISC, and can realize V2X driving fusion interaction and intelligent lighting expression. Specific functions, first, smart lighting navigation; Combined with high-precision map and navigation road planning, the next route can be guided by changing lights.

 

The second is Spot light pedestrian reminder; The infrared and visual fusion perception system of the whole vehicle is integrated to help pedestrians predict traffic risks in advance, for example, the number of seconds of traffic lights can be displayed on the lights. Third, the width-indicating optical blanket guidance; It means that the new car can recognize the road narrowing condition, automatically trigger the width-indicating light carpet in advance, and can automatically adapt to the lane line to draw the light carpet.


Fourth, the wisdom light moves with the eyes; Tracking the eyeball orientation through the camera in the car, and controlling the direction in which the headlights illuminate the driver. In addition, the smart lighting system supports flexible and personalized OTA, allowing users to design freely and enhance interest.

 

 

Zhiji’s car is equipped with an image sensor with 150 million pixels as a whole, which supports 180 distortion-free ultra-wide-angle, 4K high-definition video shooting, super night scene, high dynamic range, time-lapse photography, slow-motion photography and other modes. Videos can be edited and shared to social media with one click, and can be connected to major live broadcast platforms to broadcast live from the first perspective, and professional photography templates are provided.


This system is called Carlog, and it is extremely fresh. In the future, Kaizhiji’s car can easily record the picturesque scenery and cultural stories passing by and share them conveniently.

 

 

The eye-catching 39-inch huge display screen in the car can be intelligently lifted and lowered according to the usage scene, and there is also a 12.8-inch 2K AMOLED curved central screen on the lower side; Inside the screen is Zhiji’s IMOS system.

 

With the screen group full of science and technology, IMOS system has three characteristics, which are flowing, moist and pure. These three elegant words refer to multi-screen display respectively; Based on the weather, time, road conditions, and even based on the user’s mood, users are recommended in different scenarios; Only some necessary intuitive information is presented when driving. Sounds good? At least it aroused our strong curiosity and looked forward to the real experience.

 

From now on, charging will be intelligent. Zhiji’s car will be equipped with 11 kW high-power wireless charging for the first time in the world. It is said that the charging efficiency is almost the same as that of traditional charging, and it can charge 10.5 kWh in one hour, which is equivalent to 70-80 kilometers of battery life according to NEDC working conditions.

 

 

These intelligent abilities are relatively innovative. Then, to what extent has Zhizhi achieved the intelligence in the automatic driving ability that the industry is competing for at present?

 

The first model, namely the car, will be equipped with the NVIDIA Xavier computing platform with a computing power of 30-60TOPS, and the integrated sensing solution of 15 high-definition visual cameras, 5 millimeter-wave radars and 12 ultrasonic radars, as well as the algorithm developed based on the characteristic road conditions and driving habits in China, will form the whole system of automatic driving.


From the hardware point of view, the ability of this system is in the first-class level at present. However, the new car will be delivered in 2022, when Weilai ET7 with stronger book strength will also be delivered.

 

 

Zhiji has also considered a more radical scheme to provide new cars with upgrade redundancy in a compatible way. At present, it is not clear whether the redundant system can be installed after installation or introduced in the form of a modified model.

 

The key upgrades of this redundant system are lidar and NVIDIA Orin X chip. It is exaggerated that the number of lidar will reach three; NVIDIA Orin X chip and weilai ET7 use the same model, and the computing power will soar to 500-1000+TOPS.


As for the time point, the official said that the lidar will enter the mature stage of commercial mass production, and Zhiji Automobile will be upgraded immediately. Considering that Weilai plans to deliver ET7 equipped with lidar to users in 2022, Zhiji’s speed should not be too late.

 

 

As for the specific actual experience, the news given by Zhiji be The functions of the automatic driving system include memorizing parking and calling cars, automatically parking service and calling cars, traffic light recognition, automatic crossing, traffic jam prevention, automatic obstacle avoidance, automatic lane change, overtaking, getting on and off ramps according to the navigation path, and rear-end collision alarm.With the permission of national laws and regulations and the opening of high-precision maps, by the end of 2021, wisdomone’s ownThe car will have the ability to take over the automatic driving from point to point.

 

Zhiji focuses on automatic parking service and wake-up car. This function allows users to get off the bus and let the vehicle automatically parking service through the mobile APP; When picking up the car, the car will automatically park out of the parking space and drive to the designated location to facilitate the user to get on the bus. By the end of 2021, the functions of automatic parking service and calling cars will be applied in certain commercial centers in first-tier cities.

 

 

In 2022, it will gradually expand to specific supermarkets in first-tier and new first-tier cities. This function is quite beautiful when you think about it. After a year, the new car is delivered and you can drive Zhiji’s car to a specific shopping mall, so you can save the trouble of finding a parking space. I have to say, the development of technology is really fast. Of course, the premise is that Zhizhi can accomplish his goal on time.

 

In addition, the actual experience of the autopilot system, we have to wait until 2022 to get the answer, that is, it is not really that smart.

 

How is the performance?

 

Intelligence must be the most important ability of future cars, not power and endurance. Power and endurance in the future, everyone should do the same. Therefore, it is rational for Zhiji to focus on intelligence. Having said that, the new car released by Zhiji is also excellent in terms of power and endurance.

 

 

The new car is equipped with front and rear dual motors, and the rear axle motor is the main driving source. The total maximum power is 400 kW, and the torque is 700 Nm, which is slightly less than that of Weilai ET7, but the acceleration time of 100 kilometers is consistent with it, only 3.9 seconds.

 

Standard 93 kWh battery pack, with 115 kWh battery pack; Although the semi-solid battery technology adopted by Weilai ET7 battery pack is not adopted, it is also the first in the world to use silicon-doped lithium-supplementing technology, which realizes the ultra-high energy density of 300 watt-hours/kg, and can support Zhiji’s car to reach the battery life of nearly 1000 kilometers.

 

You don’t have to worry about the ability of the chassis. The new car is equipped with an all-aluminum chassis with a front double wishbone and a rear five-bar suspension, a brake-by-wire system, an AKC rear wheel steering system by wire, and a CDC intelligent electronic control suspension system, and the key adjustment is the responsibility of Williams professional chassis adjustment team from one of the three F1 teams.

 

 

It can be said that Zhiji represents the peak of SAIC’s strength.

 

Can the future be expected?

 

The emergence of intellectual self is aptly described by being in the right place at the right time. Tianshi refers to the intelligent and electrified industrial transformation, which represents the opportunity to change lanes and overtake into the high-end market; In addition, after years of development, the industry has reached a critical point of technological leap, and the infrastructure construction is also improving day by day. It seems that Zhiji’s admission is late, but it just happened to catch up with the good opportunity.

 

SAIC’s own brand has gained sufficient technical foundation and experience in various aspects through its development in the low-end market in the past, and SAIC itself is also quite rich, which is the geographical advantage of Zhizhi itself. People and better understanding, the background and resources that Alibaba and Zhangjiang Hi-Tech can bring need not be said.

 

 

When I came out of Zhiji’s release venue, Shanghai Tower, the tallest building in China, and looked up at this 632-meter symbol of China’s economic take-off, I couldn’t help feeling again that, like the smart phone industry, China will surely make breakthrough progress in the future of the automobile industry and become the most important pole in the world.


And the new intellectual will witness this process; And what is its own fate? After reading our introduction, what do you think of it?

AITO asked the M7 declaration map to be exposed, with its own Huawei system, and the arrow is on the line!

At the end of last year, Celeste and Huawei officially released the AITO Jiejie brand, and then launched the brand’s first model, the Jiejie M5. This year, Huawei officially launched the new model, the Jiejie M7 again. Recently, the M7 declaration map was exposed, and it was also positioned as a medium and large SUV, which had a slight collision with Li ONE in the same model. Let’s take a look at the works of the big brother in science and technology in the automobile industry.

In terms of appearance, most of the design elements of M7, including inverted trapezoidal grille and penetrating taillights, remain the design of M5. The front and rear door handles of the new car are designed in a hidden way, which is also a popular design technique for new energy vehicles at present, creating an intelligent and scientific effect. The overall body shape is smooth and elegant, but it lacks some sense of science and technology compared with some new models on the market, and it has also been vomited by some netizens that the design is "too old-fashioned". Compared with Li ONE, it is more scientific and technological. It seems that the M7 is more suitable for business people who pursue large space or car owners who prefer calm models.

In terms of body size, the length, width and height of the M7 are 5020/1945/1775 mm and the wheelbase is 2820 mm, which is close to the body size of Li ONE. The new car will also adopt the 6-seat layout of 2+2+2. After all, in the new energy market, large-size 6-seat SUVs are still very popular. However, Li ONE, as the biggest competitor of the M7, is also a 6-seat large-size SUV of the new energy model, and its size is extremely close. I wonder if it will be affected. In addition, the rear row of the new car is also designed with a rear privacy glass configuration to make the car more private.

In terms of power, the M7 is a hybrid electric vehicle equipped with h15rt 1.5T four-cylinder extended range engine. The maximum power is 92kW, and the fuel consumption of engine wltc is 1.05l/100km. Li ONE is also equipped with an extended-range hybrid system, which consists of a 1.2T engine and a brand-new drive motor, and is equipped with an ideal self-developed Li OS system and a millimeter-wave radar with driving assistance. Although there is no official data on battery capacity and battery life, the battery life of M7 will not be weaker than that of Li ONE, and the power system is really hard to tell.

At present, the interior of Wenjie M7 has not been made public, but it is understood that the new car will adopt the simple scientific and technological style similar to Wenjie M5, full LCD instrument and an oversized central control panel, and it has a built-in HarmonyOS OS intelligent cockpit. Presumably, its powerful ecological function will also bring different surprise experiences to Huawei’s new and old users.

From the price point of view, it is estimated that the selling price of M7 will be above 300,000, while the guiding price of Li ONE is around 349,800. If M7 can be lower than this selling price, the competitiveness will be more imaginative.

Although the official has only released the appearance and some dynamic information at present, judging from these data and the performance of M5, the launch of M7 is still worth our expectation. After all, it is a brand launched under the leadership of Huawei with strong scientific and technological strength. Let’s wait and see.

Where is the difficulty in mass production of solid-state batteries?

    Solid-state batteries not only have high safety and high energy density, but also have excellent "high and low temperature" performance. All kinds of advantages make people look forward to them, and they are regarded as the next generation of power batteries, and also the strategic commanding heights for countries to compete. However, at present, all three technical routes have corresponding basic shortcomings that need to be solved urgently, and the cost is also an insurmountable hurdle for enterprises.

  Toyota Motor Corporation recently announced at the technical briefing that it has found good materials to commercialize solid-state batteries from 2027 to 2028 and put pure electric vehicles equipped with all-solid-state batteries on the market. However, because Toyota did not publish convincing technical details, it caused public opinion to question.

  Solid-state batteries not only have high safety and high energy density, but also have excellent "high and low temperature" performance. All kinds of advantages make people look forward to them, and they are regarded as the next generation of power batteries, and also the strategic commanding heights for countries to compete. Thirty years ago, Oak Ridge National Laboratory claimed to have built a solid-state battery, but it is a pity that it has not been mass-produced so far. In the past two years, with the popularity of new energy vehicles around the world, many companies have reported the progress of mass production of solid-state batteries, but after the news was exposed, there was no more.

  According to the material system, solid-state batteries can be divided into three technical routes. Japan and South Korea are betting on sulfide systems. In Europe, the main route is polymer, while in China, the main route is oxide. Among them, Japanese and Korean companies, represented by Toyota, Samsung SDI and Hitachi, have profound technology accumulation and obvious first-Mover advantage, and the trend of joint research and development is obvious. However, these three technical routes all have corresponding basic shortcomings that need to be solved urgently.

  Specifically, sulfide electrolyte has poor air stability, and when it is exposed to air, it will produce toxic gas. At the same time, with the destruction of electrolyte structure and the attenuation of electrochemical performance, the synthesis, storage, transportation and post-treatment of sulfide electrolyte need to rely heavily on inert gas or drying chamber. At room temperature, the ionic conductivity of polymer electrolyte is low, which makes the charging of polymer solid-state battery need to be completed in high temperature environment, which greatly limits its commercialization. Most oxide electrolytes have wider electrochemical stability "window" and better oxidation stability, but in order to ensure good interface contact between rigid oxide electrolytes and cathode materials, it is often necessary to sinter at high temperature, otherwise it will lead to serious interface chemical side reactions. In addition, some oxide electrolytes also have the problem of lithium dendrite growth.

  At the same time, cost is also a difficult hurdle for enterprises to overcome. At present, the cost of semi-solid battery is much higher than that of commercialized liquid battery. According to industry research and calculation, taking NCM811 liquid battery and NCM811 semi-solid battery as examples, the cost of semi-solid battery increases by about 80% compared with that of liquid battery. Among them, the cost of solid electrolyte is the main new cost and the main cost in semi-solid battery, accounting for about 50%. Due to the change of electrolyte material, production process and lack of experience in product quality control, the cost of all-solid battery is higher than that of semi-solid battery.

  There are five main indicators to measure whether a power battery can be mass-produced, namely, energy density, charge-discharge rate performance, cost, safety and cycle life. The laboratory research results of power batteries generally make a major breakthrough in one or several indicators at a certain stage, and it is possible to mass-produce them only when they meet the requirements of five indicators. In other words, as far as the current research and development progress of major enterprises is concerned, solid-state batteries seem to be "windy", but in fact they are "long and long", and the mass production is still quite difficult.

  Compared with structural innovation, the improvement of battery materials is slower and indeed more difficult. However, being difficult does not mean not doing it. We often say that it is reasonable to do the "difficult and correct thing". From the perspective of technological change, the technological innovation of power battery has played a major role in promoting the development of automobile electrification. The reason why China’s new energy automobile industry can lead the world is that we have surpassed the power battery, and a global power battery giant like Contemporary Amperex Technology Co., Limited was born.

  In the industrial transformation driven by the goal of "double carbon", the innovation of power battery has become the key to strengthen the competition level of new energy vehicles, build the national industrial competitiveness and stabilize the competitive advantage of enterprises. Whether it is the first country or the catch-up country of new energy vehicles, or the main enterprises of the power battery chain, they are all aiming at new technologies and laying out solid-state batteries. This is both a great challenge and a rare opportunity. Super-large-scale market advantage, leading industry-wide competitiveness and rising innovation make China more qualified to win the strategic commanding heights of power batteries.

Foolish operation Tik Tok rose 160,000 yuan in a single month and realized 200,000 yuan.

Hello, I’m Guo Yaotian, also known as Guo Shao.

After sending the children to class in the morning, I went out to visit a few bosses. One is WeChat official account Entertainment Account, which is currently 100,000+.He said that there are actually only 800,000 fans, and this account can be realized about 10 million a year. I always thought that entertainment fans didn’t make much money, which opened my eyes. We talked a lot, gave me a lot of ideas, and it was really ok to play. Later, I will share some with you publicly.

In addition, I also visited two local bosses in Tik Tok, both of whom are awesome in exploring shops in the same city. Millions of local fans have good income. If you are interested in studying exploring shops in the same city, I can introduce it to you. It’s really ok to play. Let’s start today’s theme, which is how to operate Tik Tok like a fool and how to realize it quickly.

Speaking of short video live broadcast, I started doing it in 18 years. At that time, Tik Tok was not very popular, so I started to make short videos, invested hundreds of thousands, bought equipment, and found someone to do it. I didn’t expect that nothing was done after a few months. After I got it, I was a little disgusted with short video live broadcast. I knew it was the current trend, but I was afraid. However, I was told a few cases by WeChat official account’s eldest brother today, which really stimulated me, and I can make money so quickly. It can be said that as long as I can speak normally, I can make money by stupid operation.

His gameplay is to use the live broadcast to pay for knowledge, sell courses and sell books. I said, can’t fans do it? He said that there is no need for fans at all, and 0 fans can start broadcasting. He said that the current recommendation mechanism in Tik Tok, as long as you insist on live broadcast and pay some fees, will soon be able to set up an account. He showed me an operation case, that is, they prepared a set of live broadcasts and repeated this content every day. At present, the result is a monthly increase of 160,000.

He said that the video of this account is also relatively simple. The video does not need to be shown by real people. Just print out the phonetic symbols and 26 letters, read them out and record them. He said that the current account has just started selling courses for about a week, and the effect is still relatively good. At present, the order has come down to more than 100,000, and it will soon be 200,000.

He said that there wasn’t a set of words that could be copied before, but now it can be copied to others in batches. As long as it takes about two hours to broadcast live every day, you can quickly attract fans. All you need to do is repeat the same words every day, just do it like a fool. He said that I remembered a case that I studied in Guizhou at that time and said Tik Tok dry goods. I went in for a week in a row and repeated the same content.

What he sells is some live documents, live books, and live stands. There are tens of thousands of income every day. I didn’t expect this game to play many places in batches, mainly because there are many people in the live broadcast room every day. If someone wants to drain, he will be rewarded, so the reward money every day is a lot of money in Tik Tok.

It’s a case of a live broadcast of the same speech. I didn’t expect that some people would copy and operate this mode in batches now, so some industries can do this. This big brother suggested that I set up business-related accounts in batches, prepare good words, broadcast live in batches, and drain the traffic to WeChat official account. There is also my current content to be distributed all over the network, and convert the text into video and audio.

Later, it really takes time to do this thing, and there are many dry goods to share later.

Power battery scrapping tide is coming, recycling must be traced back to the source.

  In order to avoid the "small workshop" of recycling with crude technology and backward technology from affecting the overall healthy development of the industry, the newly revised "Industrial Standard Conditions for Comprehensive Utilization of Waste Power Batteries of New Energy Vehicles" upgraded the environmental protection requirements. For example, the on-line monitoring devices for wastewater, waste gas and industrial solid waste generated in the process of comprehensive utilization have been changed from "encouraging installation" to "should have".

  The production and sales of new energy vehicles in China have ranked first in the world. According to the data released by China Association of Automobile Manufacturers, 1-mdash in 2019; In August, the sales volume of new energy vehicles in China was 793,000, maintaining a year-on-year growth rate of 32%. With the large-scale popularization and application of new energy vehicles, the comprehensive utilization of waste power batteries is particularly urgent.

  Recently, the Ministry of Industry and Information Technology has recently revised and officially solicited opinions from the public on the industrial standard conditions for the comprehensive utilization of waste power batteries in new energy vehicles (hereinafter referred to as the standard conditions) and the Interim Measures for the Administration of the industrial standard announcement for the comprehensive utilization of waste power batteries in new energy vehicles (hereinafter referred to as the Measures) issued in 2016, which put forward requirements for the comprehensive utilization of power batteries to be more perfect, safer, more energy-saving and environmentally friendly.

  Recycling is still in its infancy.

  According to the calculation of China Automotive Technology and Research Center, combined with the factors such as automobile scrapping years and battery life, in 2018 — In 2020, the total number of scrapped power batteries in China will reach 120,000 — 200,000 tons, reaching the scale of 350,000 tons in 2025. It can be said that the wave of large-scale scrapping of power batteries for new energy vehicles is coming.

  "The service life of power batteries is generally 5-mdash; 8 years, the effective life is 4-mdash; In 6 years, this means that the first batch of new energy vehicle power batteries put into the market are basically at the critical point of elimination. " Zhang Tianren, Chairman of Tianneng Group’s Board of Directors, told the Science and Technology Daily reporter that when the capacity of power storage battery decays below 80%, it will not fully meet the power demand of automobiles and can be used in other fields step by step.

  The "Investigation Report on Recycling and Utilization of Power Batteries in New Energy Vehicles (Introduction)" issued by the Ministry of Industry and Information Technology shows that most of the current cascade utilization of power batteries is in the experimental demonstration stage, mainly in the fields of power preparation and energy storage. In 2018, China Tower Company stopped purchasing lead-acid batteries, and vigorously promoted the step-by-step utilization of lithium batteries. The application of step-by-step utilization of batteries for power preparation has been carried out in about 120,000 base stations in 31 provinces and cities, and business development has been strengthened in the application scenarios of power preparation, energy storage and external power generation. State Grid has built a 1 MW-hour energy storage system demonstration project using lithium iron phosphate batteries in steps to accept renewable energy for power generation and frequency modulation.

  Zhang Tianren said that at present, there are two main destinations for retired power batteries of new energy vehicles, one is step-by-step utilization, and the other is recycling. After dismantling the scrapped batteries, the heavy metals in them will be refined and reused. "From the perspective of the whole life cycle, the batteries used in the cascade need to be recycled after they are finally scrapped." The state attaches great importance to the recycling of power batteries. In 2018, the ministries and commissions of industry, information technology, environmental protection and other countries jointly issued the Interim Measures for the Management of Recycling of Power Batteries for New Energy Vehicles and other regulations to strengthen the recycling management of power batteries, standardize the development of the industry and promote the comprehensive utilization of resources. However, the recycling of power batteries is still a new field, and it is still in its infancy, facing many difficulties and deficiencies. It is particularly critical and important to revise the Specifications and Measures in time.

  Establish a perfect and mature comprehensive utilization database

  The newly released revised draft of the Specification Conditions and the revised draft of the Measures are revised and improved on the basis of relevant documents in 2016, especially reflecting the technology and technology-driven, making the traceability and utilization of power batteries more perfect and safer.

  In the recycling of used batteries, traceability is considered to be a key link. The Interim Provisions on the Traceability Management of Power Battery Recycling in New Energy Vehicles proposes that a comprehensive traceability management platform will be established to collect information on the whole process of production, sales, use, scrapping, recycling and utilization of new energy power lithium batteries, and to test the fulfillment of recycling responsibilities by all link subjects.

  Zhang Tianren said that at present, China’s battery recycling system is not perfect, and there is no effective cooperation mechanism among automobile manufacturers, battery manufacturers, recycling enterprises and recycling enterprises, and the rights and responsibilities are not clear enough. These institutional measures have played a positive role in strengthening the efficient utilization of scrapped batteries. The further improvement of the traceability management of power batteries is highlighted in the revised draft of the Specification.

  For example, in the general requirements of "technology, equipment and technology", the revised draft of "Specifications and Conditions" added a new item, "It should meet the relevant requirements of traceability management of recycling and utilization of power batteries for new energy vehicles, and have the ability of information traceability, such as traceability information system and auxiliary facilities and equipment such as code identification." When it comes to the inability to dispose of "electronic components, metals, graphite, plastics, rubber, diaphragms, electrolytes and other parts and materials produced in the process of comprehensive utilization", it requires enterprises to "hand over relevant qualified enterprises for centralized treatment according to relevant national requirements" and "do a good job in tracking management"; In the article "Product Quality and Vocational Education", recycling enterprises are required to upgrade from "establishing a complete traceability system" to "establishing a complete information production process management system", which is also conducive to establishing a more complete and mature comprehensive utilization database of used power batteries.

  Safety is the foundation of the development of power batteries. Similarly, the revised version of Specification and Conditions puts forward higher requirements for the safety of power batteries in the process of recycling. Among them, in the "Environmental Protection Requirements" clause, more detailed treatment requirements are added for "gas" separately, "the residues that are flammable and explosive at normal temperature and pressure and discharge toxic gases generated in the process of comprehensive utilization must be pretreated to make them stable before storage, otherwise they will be stored as flammable and explosive dangerous goods"; In the clause of "Safety in production, personal health and social responsibility", a new requirement for transportation is added: "The transportation of waste power batteries should meet the requirements of relevant national laws, regulations and standards, and the battery structure should be ensured as far as possible. Before transportation, the waste power batteries should be classified according to their safety characteristics, and the corresponding transportation plan should be adopted according to relevant standards, with safety guarantee measures such as fire prevention, waterproof, explosion prevention, insulation and heat insulation, and emergency plans should be formulated."

  Key common technologies need to be broken through urgently.

  China’s lithium resources are about 7 million tons, ranking fourth in the world. However, due to the poor grade, difficult purification and high cost of lithium ore, it is necessary to import a large number of lithium ore every year, and its dependence on foreign countries exceeds 85%. "China demand" has also promoted the skyrocketing price of battery-grade lithium carbonate, from less than 50,000 yuan/ton at the beginning of 2015 to 180,000 yuan/ton at the end of 2017, an increase of nearly three times, which is not conducive to the development of new energy automobile industry and poses a serious challenge to China’s resource security.

  Zhang Tianren said that waste power batteries are precious "urban mines", and the metal content is much higher than that of ores. Recovering and recycling valuable metals such as lithium, cobalt and nickel in them can improve resource utilization efficiency and reduce external dependence. Waste power batteries will do great harm to the ecological environment if they are improperly treated and discarded at will. "Heavy metal elements such as cobalt and nickel in cathode materials, organic substances in electrolyte and carbon materials in cathode will cause serious pollution to water and soil, especially once heavy metals penetrate into soil, it will be difficult to recover for decades."

  Therefore, in the aspect of energy conservation and environmental protection, the revised draft of the Specifications and Conditions puts forward a specification for the recovery rate of lithium for the first time, that is, it is not less than 85%, and the material recovery rate should be not less than 90% if the material repair process is adopted. In order to avoid the "small workshop" of recycling with crude technology and backward technology from affecting the overall healthy development of the industry, the revised draft of "Specifications and Conditions" upgraded the environmental protection requirements. New construction, renovation and expansion of comprehensive utilization enterprises should strictly implement the environmental assessment system, and be included in the construction projects listed in the classified management list of pollutant discharge permits of fixed pollution sources, and apply for pollutant discharge permits in accordance with the relevant management regulations of the state on pollutant discharge permits; On-line monitoring devices such as wastewater, waste gas and industrial solid waste generated in the process of comprehensive utilization have changed from "encouraging installation" to "should have".

  The revised version of the Specification emphasizes that "production equipment and facilities with high production automation efficiency, advanced energy consumption indicators, environmental protection standards and high comprehensive utilization rate of resources should be selected, and new technologies and processes that are energy-saving, environmental protection, clean, efficient and intelligent should be adopted." Zhang Tianren said that at present, the recycling technology is not mature, the level of automation is low and the cost remains high. "In view of the weak links in the recycling of waste power batteries, Industry-University-Research should be organized to jointly tackle key problems, continuously improve the level of process equipment, metal refining technology, energy saving and consumption reduction, break through key common technologies, effectively reduce production costs, and gradually cultivate mature industrial systems."
