Is Lithium Battery Technology a Roadblock in China's New Energy Automobile Industry?

May 1 small long vacation, the author has nothing to do, to see Hangzhou Xibo auto show.

After a lap, I felt a lot.

New energy car curve is not easy to overtake

At present, the consumer car market includes traditional fuel vehicles and emerging new energy vehicles. Our country fuel car develops rapidly in recent years, but in the engine, chassis, counter this three big parts of the car, and the world advanced level gap is still large.

After the rise of new energy vehicles, the parts such as engines and variables that require technical accumulation are omitted. Some people think that this is an opportunity for domestic cars to overtake cars, but from the perspective of China's new energy vehicles and international comparisons, there are still many technical difficulties that need to be broken.

The gap between electric control technology and international level is obvious

As a substitute for traditional fuel vehicles, the core of the new energy vehicle is still in the power system. The system consists of batteries, motors, and electronic controls. Among them, the motor and electric control system are the core of the power system, and their performance is directly related to the main indicators such as the acceleration, performance, and climbing of new energy vehicles.

Electric technology, in particular, is the key to new energy vehicles. The electric control system is used to replace the function as a traditional engine and gearbox.

The parameters of the electronic control system, such as Operation logic and service life, are extremely demanding. At present, most of the electric control system of many new energy vehicles in our country are imported, and some independent R&D companies are still in the hands of foreigners. The difficulty can be imagined.

Safety and stability are the keys to lithium battery technology

Secondly, the lithium battery technology used in new energy vehicles, China still has a long way to go.

At present, lithium-ion battery technology is mainly focused on large capacity, small volume, rapid charging, and other aspects, in the more critical safety, stability, durability, and other aspects, China is still lacking.

Comments:

Tesla founder Musk once commented on BYD, saying that its technology is not bright and its products are too bad.

It is true that we still have a lot to learn. If these problems can be solved one day, there will be no shortage in the field of new energy vehicles in China. A respected era of new energy vehicles in China will really come.
