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 system, a first motor and a second motor are hub motors, compared with other motors, the hub motors are higher in electric energy recovery efficiency, and the electric energy consumption of the whole vehicle is reduced; switching between two-wheel drive control and four-wheel drive control can be achieved by adjusting the state of the clutch; according to the pure electric vehicle control method, when the vehicle runs, if the clutch enables the third motor to be connected with the second wheel, the hub motor and the centralized motor can jointly control the vehicle to run; and if the third motor and the second wheel are disconnected through the clutch, the hub motor can independently control 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, and the problem that the energy consumption loss is large when the 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系统,第一电机和第二电机为轮毂电机,轮毂电机相比其他电机而言,轮毂电机进行电能回收的效率更高,更加有利于降低整车电能消耗;可以通过调节离合器的状态,实现两驱控制和四驱控制的切换;本发明提供的纯电动汽车控制方法,车辆行驶时,若离合器使第三电机与第二车轮连接,可以实现轮毂电机和集中式电机共同控制车辆行驶;若离合器使第三电机与第二车轮断开连接,可以实现轮毂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。
