新能源车用驱动电机系统的匹配应用

The Matching of E-motor Systems for New Energy Vehicles

驱动电机系统作为代表新能源汽车技术核心的三电系统之一,是决定整车动力输出的关键装置。驱动电机系统与整车是否匹配,直接影响了整车的动力性、经济性、平顺性以及整车的主观驾驶感受。因此,驱动电机系统对于新能源汽车开发的重要程度完全不亚于动力电池以及整车控制系统。结合近些年来新能源驱动电机系统的技术发展趋势,以新能源驱动电机系统的技术属性作为理论依据,从新能源汽车在开发过程中对驱动电机系统的安装空间、性能、工作环境等技术要求作为出发点,浅析驱动电机系统在与新能源汽车匹配中需要注意的关键问题以及相应的解决方案。

As one of the three electric systems representing the core technology of new energy vehicles,the e-motor system is the key device to determine the power output of the vehicle.Whether the e-motor system matches with the vehicle directly affects the power performance,economy,ride comfort and subjective driving experience of the vehicle.Therefore,the e-motor system for the development of new energy vehicles is no less important than the power battery and vehicle control system.In this paper,combined with the technical development trend of the new energy e-motor system in recent years,the technical attributes of the new energy e-motor system as the theoretical basis,the installation space,performance,working environment and other technical requirements of the e-motor system in the development process of new energy vehicles as the starting point,analysis of e-motor system in the matching of new energy vehicles need to pay attention to the key problems and corresponding solutions.
