The invention relates to the technical field of electric driving control, and provides an electric driving system for an electric automobile and a control method of the electric driving system. The electric driving system for the electric automobile comprises a motor body and a motor shell arranged outside the motor body. An electric control management module is arranged between a stator shaft anda rear end cover, a power device 1 and a power device 2 are correspondingly arranged on the two sides of the electric control management module, the power device 2 is arranged close to the rear end cover, the power device 1 and a radiator arranged in the motor body make contact with a motor water jacket, a water inlet and a water outlet of the motor water jacket communicate with a whole vehicle cooling system, a three-phase loop of the power device 2 is fixed to an aluminum base plate through a busbar, and the aluminum base plate is connected with a passenger compartment shell through a heatdissipation layer. The electric control management module is integrated in the motor shell, the integration level of the electric driving system of the electric automobile is higher, and cost saving is facilitated under the condition of not affecting the heat dissipation performance.

    本发明涉及电驱动控制技术领域,提供了一种电动汽车用电驱动系统及其控制方法,该电动汽车用电驱动系统包括:电机本体及设于电机本体外的电机壳体,电控管理模块设于定子轴与后端盖之间,在电控管理模块的两侧分别设有功率器件1及功率器件2,功率器件2靠近后端盖设置,功率器件1及设于电机本体内的散热器与电机水套接触,电机水套的进水口及出水口与整车散热系统连同,功率器件2的三相回路通过母排固定与铝基板上,铝基板通过散热层与乘客舱壳体连接。电控管理模块集成于电机壳体内,电动汽车电驱系统的集成度更高,在不影响散热性能的情况下,有利于节省成本。
