AA Carbon battery

　　Is AA Carbon battery technology a stumbling block for my country’s new energy automobile industry?

　　During the May Day holiday, the author had nothing to do and went to see the Hangzhou Xibo Auto Show.

　　After a lap, I felt a lot.

　　It is not easy for new energy vehicles to overtake on curves

　　Currently, the consumer automobile market includes traditional fuel vehicles and emerging new energy vehicles. my country's fuel vehicles have developed rapidly in recent years, but there is still a large gap with the world's advanced level in terms of the three major components of the vehicle: engine, chassis, and transducer.

　　After the rise of new energy vehicles, parts that require technical accumulation such as engines and transducers have been omitted. Some people believe that this is an opportunity for domestic cars to overtake in a corner. However, judging from the comparison between my country's new energy vehicles and international ones, there are still There are also many technical difficulties that need to be overcome.

　　There is a clear gap between electronic control technology and international standards

　　As a substitute for traditional fuel vehicles, the core of new energy vehicles is still the power system, which consists of batteries, motors, and electronic controls. Among them, the motor and electronic control system are the core of the power system, and their performance is directly related to the acceleration, efficiency, climbing and other major indicators of new energy vehicles.

　　Especially electric technology, which is the key to new energy vehicles. The electronic control system is used to replace the functions of the traditional engine and gearbox.

　　The parameter indicators of the electronic control system, such as operating logic and service life, are extremely demanding. At present, the electronic control systems of many new energy vehicles in our country are mostly imported, and some independent research and development companies still have ruthless technology in the hands of foreign parties. You can imagine how difficult it is.

　　Lithium battery technology, safety and stability are key

　　Secondly, there is the lithium battery technology used in new energy vehicles. my country still has a long way to go.

　　At present, lithium battery technology research is mainly focused on large capacity, small volume, fast charging, etc. Our country is still lacking in the more critical aspects of safety, stability, durability, etc.

　　Comments:

　　Tesla founder Musk once commented on BYD, saying that its technology has no bright spots and its products are terrible.

　　It is true that we still have a lot to learn. If one day these problems can be overcome, there will be no shortcomings in the field of new energy vehicles in my country, and a respectable era of new energy vehicles in China will truly come.
