Electric vehicle refers to a vehicle that is powered by an on-board power source and uses an electric motor to drive its wheels, meeting various requirements of road traffic and safety regulations. It uses electricity stored in the battery to start. Sometimes 12 or 24 batteries are used to drive the car, and sometimes more are needed.

According to statistics, the composition of China's chemical industry equipment and technology independent innovation is generally only about 10%, but in the chemical basic theory and new chemical materials research, there are fewer theoretical breakthroughs and core technologies, directly becoming a constraint on the autonomy of China's chemical companies Innovation bottlenecks. Due to lack of original technology, China has become a processing factory of chemical products in the world. After paying a huge environmental price, the bulk of profits was taken away by foreign chemical giants with original technology.
It is said that the enterprise is the main body of independent innovation and should take the initiative in carrying out the basic research. However, most of the traditional chemical companies in China are outdated equipment, backward technology, heavy burden, unrelenting in the current fierce market competition, coupled with the risk of the chemical industry, Inadequate attraction for high-tech talent, and the general lack of innovative talents engaged in basic theoretical research. In addition, due to the large number of areas involved in basic research, it is difficult to bear the burden of a single chemical company alone. Therefore, the reality is that, in addition to a number of innovations in some process processes and equipment reforms, chemical companies rarely make a difference in basic research.
As a matter of fact, not only is it difficult for enterprises to undertake basic research tasks, but also some chemical research institutes that have been serving as the graduates of China's chemical engineering base. After the original Ministry of Chemical Industry was revoked, they were mostly transformed into business entities seeking food in the market, relying on research and development of practical applications. Technology or the development of some products for enterprises to survive, the pursuit of quick success and instant benefits, has long been engaged in the basic research of the mind and strength.
Therefore, under the current situation that chemical companies do not have the capability or the motivation to carry out basic research, the country should increase the strategic position of chemical basic research through the coordination of industry associations through policy guidance and financial support, and integrate the existing chemical industry. The research resources, through the dual forces of policy and market, have completely changed the status quo of China's basic chemical industry research and improved the independent innovation capability of chemical companies.
The composition of electric vehicles includes: electric drive and control systems, mechanical systems such as driving force transmission, and working devices to complete predetermined tasks. The electric drive and control system is the core of electric vehicles and the biggest difference from internal combustion engine vehicles. The electric drive and control system consists of a driving motor, a power supply, and a speed control device for the motor. The other devices of electric vehicles are basically the same as those of internal combustion engines.
Efforts to transform basic enterprises into basic research tasks
At the 17th Shanghai International Chemicals Exhibition that was held not long ago, although there are many bright spots in the independent innovation technologies and products of China's chemical companies, the overall proportion is not large, and the gap between the international advanced level and the industry is obvious. The reason is that the basic research in China's chemical industry is too weak. Judging from the current situation, most chemical companies still have difficulty in undertaking the basic research.
