The invention relates to the field of vehicles, and discloses a pure electric vehicle power system, a pure electric vehicle and a control method. According to the pure electric vehicle power system, a first motor and a second motor are wheel-side motors, and a third motor is a centralized motor; when the first motor is in transmission connection with a corresponding first wheel through a first clutch and the motor is in transmission connection with the corresponding first wheel through a second clutch, the wheel side motor and the centralized motor jointly control the vehicle to run; when the first motor and the corresponding first wheel are disconnected through the first clutch and the motor and the corresponding first wheel are disconnected through the second clutch, the centralized motor independently controls the vehicle to run, switching of two-wheel-drive control and four-wheel-drive control is achieved, the two-wheel-drive control or the four-wheel-drive control can be selected conveniently according to actual requirements. Therefore, the problem that the energy consumption loss is large when four-wheel drive control is adopted for a long time is solved.

    本发明涉及车辆领域,公开了一种纯电动汽车动力系统、纯电动汽车及控制方法,本发明提供的纯电动汽车动力系统,将第一电机和第二电机均采用轮边电机,第三电机采用集中式电机,通过第一离合器使第一电机和对应第一车轮传动连接且通过第二离合器使电机和对应的第一车轮传动连接时,实现轮边电机和集中式电机共同控制车辆行驶;通过第一离合器使第一电机和对应第一车轮断开连接且通过第二离合器使电机和对应的第一车轮断开连接时,实现集中式电机单独控制车辆行驶,实现两驱控制和四驱控制的切换,便于根据实际需求选择两驱或四驱控制,以避免长期采用四驱控制时耗能损失较大的问题。
