　　The lithium battery industry attracts hundreds of billions of dollars. Where does the golden compass point? Tongxin Smart Manufacturing Network Summit Forum--2018 China (International) Lithium Battery and Electric Technology Development Summit Forum was held in Shanghai from April 20-21. This conference was co-sponsored by the First Lithium Grid, Heli Exhibition, and Tongxin Smart Manufacturing Network At the same time, the China International Electric Vehicles and Charging and Swap Technology Summit Forum will be held at the same time. More than 40 guests were invited to the forum to share speeches. More than 500 representatives of related companies in the lithium battery industry from all over the country attended the forum. Lei Hongjun from Yangtze River Bus gave a keynote speech on "Utilization and Reference of Patented Tesla Pure Electric Vehicle Technology".

　　Thanks to the organizer for inviting to participate in the BRICS Lithium Battery Summit. My work unit is the chief engineer of Hubei Urban Bus Engineering Technology Research Center. He has been making complete vehicles for more than 40 years. We went to Wuhan to take a look. Wuhan electric vehicles are made by us. A BRD is the first, it is pure electric, and it may be the first in the world, so I can only say that. Why participate in this meeting? As a user unit, I have an understanding of batteries. Otherwise, I don’t know how to engage in lithium batteries. It is not necessarily the aspect of lithium batteries. The external characteristics include the pace of progress. There is also a graphite battery appealing for a long time. In December last year, we asked him hopefully the bonus in the United Kingdom if we could mention it on the battery. A dozen of us saw the bonus teacher, just like Dr. Zheng, who didn’t understand what we were talking about. Later we learned that graphene was made. It’s material grade. I don’t know where the material is. Later, I figured it out. Many people are talking about graphene batteries. As a vehicle manufacturer, I don’t know how to do batteries. I know that the process is good for the development of models. What is the point of telling you this today? What kind of batteries do I want? What is the second new energy vehicle? New energy. If the car can't go down, there is no pollution.

　　What do we do? The first point is that our country promotes new energy vehicles until today. I feel that the first pair of batteries is safe. Lithium batteries have been unsafe for three or four years, but I don’t understand them. Later, you are not safe on the whole. To me, I can honestly say that your battery is not responsible for much, thank you all. Just now I honestly said that there was an internal short circuit, and now I find that what I know basically has nothing to do with the battery manufacturer, but we have not figured it out. Thank you. Why didn't you figure it out? The first line will not be connected. When I first developed the high-voltage line, when did I use the low-voltage line as the high-voltage line. I used to be a trolley car who knew high-voltage very well. The BYD car burned when it burned. There is no battery level. Many experts see Stop talking, like a light bulb. Today, I see that solid batteries are not coming out. Gasoline is dangerous. I have full confidence in the development of China's energy vehicles and electric vehicles. At the same time, I would like to express my high respect to the teachers in the electronics industry. I will tell you how to do it.

　　First, electric vehicles. First of all, we are new energy vehicles at the central level. I don’t know how to do it at my level. My level is electric vehicles. Are electric vehicles new energy vehicles? The central government said that the new energy vehicle standing here is an electric vehicle. In other words, the power battery provides power to the motor. It is called a new energy vehicle. I don’t know if it’s right? There are a few concepts here. Is methanol, ethanol, test machine or not? My understanding is not, because I always say that new energy vehicles are the first to understand that there is no new energy. Do you agree with this point of view? Is there new energy? The answer is no, but there must be, thank you. What's the meaning? Energy itself exists objectively. It is necessary to use the previously useless energy. This energy is new. Is there any reason? Does it mean this? Let’s stop arguing. Many experts say that we are fooling around. New is a concept? It’s new too. It’s been useless for many years, and it’s new again. Is it the bridegroom and the bride that two people divorced and then remarry? It is the beginning of a new life. How to do the car? We started to take down the engine, put the battery down, and put the motor on. We kept getting scolded that we didn’t use our brains and told everyone that we couldn’t do it, we couldn’t be a person, and the chassis could not be developed. We have been doing it, how to do it, let’s take a look at Tesla now, see how it does it, and where it does it.

　　No matter the level of technology is incomparable with the United States, but it must be learned, but there is a feature that the Chinese can't do it themselves. Some people say that everyone says that everyone has no objection. Let’s take a look at how American cars are made. This is the case. Many people recommended to me, saying that we, Rengu Electric, walked in the Shanghai Auto Exhibition for two days, and asked if there is no such electric motor in the world. I am confused. Why do you not use it? It’s almost impossible to make a bus with electric motors and energy electric motors, and how to use them if they can’t. What does it mean that we must continue to develop electric vehicles? You can rest assured that this is a national strategy and the only way to become a powerful automobile country. Why do many people in Rengu Motor and Energy Motor do it? I think a technology is just a technology product. We are now In the industry, whether the industry can be built is very important. We have a lot of technology and personnel. How to build the industry chain? Why can't Rengu Motor and Energy Motor be able to make it? Sla, Tesla’s motor is 12,000 rpm, and Tesla’s industrial chain is good. It is worth learning. To surpass it, we must first figure out what degree it is.

　　Okay, because Tesla has always said that this car is not a car at all, and that this is a toy car, which is also right, because this car is too expensive and no one buys it. It has always been said that this car is a toy car, but it is still worth learning. .

　　Tesla does not care about the cost. We care about the cost, so it is in place. What kind of car does it care about the cost? The car we want is 100,000, 150,000, and the highest is 200,000. Its car is 500,000, 800,000 and 1 million. If I have 1 million, I can make it, I said in batches.

　　This car is about 75,000 cars, so because it does not count the cost, Tesla is going to replace the fuel car, and the replacement is not replaced. What is the replacement is also the content of the industry’s daily meetings. First, I think replacement is inevitable. The time for replacement is a process, but many vehicles will definitely be replaced in the past few years. At present, all buses in Shenzhen are replaced by pure electric vehicles, Shanxi is replaced, Shenzhen is replaced, and Wuhan is also replaced. It’s almost over. It’s not a false proposition that electric vehicles can replace fuel vehicles. Whether people can replace them completely is a matter of time. I estimate that passenger cars will be replaced. It is estimated that the time will be very fast. Trucks are not very replaceable. There will be a period of time. .

　　The problem now is that I have never known that there are 18650s in electronics. I have not figured out why I need to make specifications. Can 18650 be 19650? I don’t understand, I’ll tell you that, in fact, depending on the variety, there are many varieties. Here are some sayings that 18650 is very safe. This is what you told me. I don’t understand. Tell you about it. You do it. The battery is not usable at all. Our manufacturers don’t want batteries. We need power supplies. Thank you all the leaders here. We have not talked about power supplies. We have been talking about batteries. We have not attracted our manufacturers. We are here to learn. We will come. You have been talking about batteries in the past two days. You brag about yourself, not for users. This is what I learned below. At least 5 years at present, at the current industrial level in China, this model is learned. What does it mean for the main motor at the back and the auxiliary motor at the front? In this mode, replacing the original engine with a motor is completely useless and has no technical level, but I have learnt about it from Tesla. Rengu Motor and Energy Motor do not.

　　What does that mean? Now we use a central motor, one motor is placed in the center, why can't it be done? Let me implement my profession and brag about it. This is the concept now. The engine is not directly driving the car. Do you know the number of revolutions of the engine? What is the speed of the car? How many revolutions does the engine rotate? Yeah? The speed of the car is in kilometers. The speed of the engine in this place is not an order of magnitude and the same level as the speed of the car. So our car has two meters, one is the odometer and the other is the engine. Here, a gearbox is used. The real car is not the engine, but the gearbox. Do you agree? The second question is, what’s the problem when the car is eliminated. The car has 4 wheels. When turning left and right, the radius of the inner wheel and the outer wheel are different. There is a differential in it. This differential can’t be done. There are two difficulties. One is the speed. It is neither high nor low. It is estimated that within five years, our structure will be the same as Tesla, and we can maintain the level of Tesla. It is impossible to exceed it.
