The invention relates to an electric automobile accessory driving system. The system comprises a traction motor, a gear box, a driving shaft, an accessory motor and an accessory product, the tractionmotor drives the driving shaft to rotate through the gear box, the accessory motor drives the accessory product to work, and the accessory product at least comprises one of a compressor, a water pump,an air pump, a vacuum pump and a steering pump; and when the electric automobile decelerates, the kinetic energy of the electric automobile drives at least one of the accessory motor, the traction motor and the accessory product to operate. The accessory motor of the electric automobile accessory driving system can recover kinetic energy of the electric automobile when the electric automobile decelerates, can drive an accessory product to work and can also drive the electric automobile to run. Therefore, more energy can be recovered in the presence of the accessory motor, so that the energy utilization efficiency is improved.
本发明涉及一种电动汽车附件驱动系统,其包括:牵引电机、齿轮箱、驱动轴、附件电机和附件产品,所述牵引电机通过所述齿轮箱驱动所述驱动轴转动,所述附件电机驱动所述附件产品工作,所述附件产品至少包括压缩机、水泵、气泵、真空泵和转向泵中的一种;当所述电动汽车减速行驶时,所述电动汽车的动能驱动所述附件电机、牵引电机和附件产品中的至少一个运作。该电动汽车附件驱动系统的附件电机能够在电动汽车减速时回收电动汽车的动能,并能够驱动附件产品的工作也能驱动电动汽车行驶。这样附件电机的存在就可以回收更多能量,从而提高能量利用效率。
