In terms of batteries, future technological development is mainly concentrated in high-performance battery materials, battery packs, battery management systems, battery cascade utilization recycling technology and battery manufacturing and other fields, domestic battery technology to achieve advantages need to have two basic conditions: battery energy density to be as high as possible, at the same time, battery cost to be as low as possible.
In terms of motor, the main share of domestic drive motor is occupied by permanent magnet motor, due to China’s rare earth resources have certain advantages, the future permanent magnet motor is still the focus of new energy vehicle drive motor development, but from the motor controller continuous power point of view, there is still a certain gap compared with the international advanced level. In the future, the use of silicon carbide to improve the power density of motor controller will be one of the mainstream trends in the development of motor controller technology.
In terms of electric drive, at present, foreign electric drive system integrators represented by Bosch, Magna, BorgWarner, etc., have launched electric drive integrated assembly products, China and foreign countries basically started at the same time, and achieved a leading position, such as Shanghai electric drive, BYD, KR, Huawei, etc., have popularized the three-in-one assembly system. And many manufacturers have generally adopted integrated on-board power supplies and even VCU, BMS multi-in-one electric drive systems. Overall, the integration of electric drive systems has become the development trend of new energy vehicle technology.
In terms of thermal management system, due to the bottleneck of battery energy density improvement at present, reducing vehicle energy consumption is particularly critical. Thermal management system can improve technology development by optimizing popularization of heat pump air conditioning, accelerating penetration of integrated application, continuation of local cost reduction and efficiency, and promoting air conditioning refrigerant upgrading by environmental protection. At the same time, optimizing cooling technology, system layout and thermal simulation analysis technology. The efficiency of the thermal management system can be further improved.
