The three core technologies of pure electric vehicles - motor, electronic control and battery.
　　 Batteries are the source of power for electric vehicles and they have also been a key factor in restricting the development of electric vehicles. The main performance indicators for electric vehicle batteries are specific energy (E), energy density (Ed), specific power (P), cycle life (L), and cost (C). To make electric vehicles competitive with fuel vehicles, the key is to develop high-efficiency batteries with high specific energy, high specific power, and long service life.

The energy management system is the smart core of electric vehicles. A well-designed electric car, in addition to good mechanical properties, electric drive performance, and an appropriate energy source (ie, a battery), should also have an energy management system that coordinates the work of each functional part. Its role is to detect individual The state of charge of the battery or battery pack, and based on a variety of sensing information, including force, acceleration and deceleration commands, road conditions, battery conditions, ambient temperature, etc., reasonably deploy and use limited on-board energy; it can also be based on battery Group usage and charge/discharge history select the best charging method to maximize battery life.
The draft of the "Automobile and New Energy Vehicle Industry Development Plan (2011-2020)" said that in the next decade, the central government will invest 100 billion yuan to support the research, development, and promotion of core technologies for energy-saving and new energy vehicles. It is planned that by 2020, the industrialization and market scale of China's new energy vehicles will reach the top in the world, and the number of new energy vehicles will reach 5 million.
News of the Ministry of Commerce website released on July 20th: According to McKinsey’s latest “Electric Vehicle Index†released in July, China’s ranking has risen to third place, tied with Germany, and significantly better than the previous index. In the seventh place, the top two are the United States and France, and Japan, South Korea, Italy and Denmark are ranked behind China and Germany. McKinsey pointed out that the Chinese government has adopted a series of support and incentive measures to promote the production and sales of electric vehicles. Chinese automobile manufacturers have also expanded their existing electric vehicle series and production.
