Unexpected market potential, interpretation of electronic control information for new energy vehicles
Under the support of the state's policy of vigorously promoting the development of new energy vehicles, the entire new energy vehicle industry has shown a booming trend. As the largest market for new energy vehicles, Chinese companies rely on new energy vehicles to stand on the same starting line with foreign companies for the first time, and the driving motor and control technology, which is an important component of new energy vehicles, also determines the future development of new energy vehicles. The breadth and breadth of its importance are self-evident.
At present, the main types of motors on the market are AC asynchronous motors and permanent magnet synchronous motors. The permanent magnet synchronous motors occupy the largest share of the domestic motor market due to their high efficiency, high power density and small size, and are mainly used in the passenger vehicle field.
AC asynchronous motor is relatively simple due to its low cost and simple structure, and its control technology is relatively mature. However, its large size and heavy weight all restrict its wide application to a certain extent, mainly used in new energy. Passenger cars and some passenger cars.
Through the production data (motor electric control) of the new energy vehicles sold by Gasgoing Automotive Research Institute, it is found that in the Chinese market, most of the pure electric vehicles use permanent magnet synchronous motors. According to statistics, among the 157 pure electric passenger cars, there are 113 models using permanent magnet synchronous motors, 40 types of AC asynchronous motors, 2 types of excitation synchronous motors, and 1 type of external excitation synchronous motors. In the Hybrid HEV, all 17 models use permanent magnet synchronous motors. Among the plug-in hybrid PHEVs, all 28 models use permanent magnet synchronous motors, and the Cadillac CT6PHEV uses dual motors including AC asynchronous motors and permanent magnet synchronous motors.
In the field of passenger cars, permanent magnet synchronous motors also occupy the mainstream. According to statistics, among the 377 pure electric buses, there are 354 models with permanent magnet synchronous motors, 21 models for AC asynchronous motors, and two models for permanent magnet DC motors. Among the plug-in hybrid buses, there are 123 permanent magnet synchronous motors and 16 AC asynchronous motors. The other two fuel cell buses also use permanent magnet synchronous motors. It can be seen that in the field of new energy passenger cars and commercial vehicles for sale in China, permanent magnet synchronous motors have become the absolute mainstream.
At present, the global new energy vehicle drive motor and electronic control market are dominated by OEMs, traditional auto parts companies and professional motor electronic control companies. Among them, professional motor companies in the domestic new energy vehicle drive motor market occupy the largest market share. . Through the production data (motor electric control) of the new energy vehicles sold by Gasgoing Automobile Research Institute, it is found that among the independent brands, Beiqi New Energy, BYD, Dongfeng, Haima Automobile, Jiangnan Automobile, Jiulong Automobile, Jiangling New Energy, Changan Automobile, Zhongtai Automobile All of them are made of self-made motor electronic control package.
Through the production data (motor electric control) of the new energy vehicles sold by Gass Automotive Research Institute, the market share of professional motor electronic control companies is on the rise. Among the motor supplier packages, Anhui Juyi, Shanghai Electric Drive and Shandong Deyang have appeared in their own brand models.
It is predicted that the global market for drive motors will reach 4.4 billion US dollars by 2020, and most of the main control plants are in line with the motor suppliers. Under the high-efficiency matching requirements, the integration of motor electronic control is new energy. The inevitable trend of the car, the market potential is endless.
