The invention provides an electric vehicle water pump driving structure and method and an electric vehicle. The driving structure comprises a driving motor, a water pump motor and a water pump. The driving motor is in transmission connection with the water pump through a driving shaft to drive the water pump to rotate; the water pump motor is in transmission connection with the water pump througha water pump motor shaft to drive the water pump to rotate; the driving motor and the water pump motor can be mutually switched under different operation conditions of the electric vehicle to drive the water pump to rotate respectively; by adopting the technical scheme, the driving motor and the water pump motor are arranged on a water pump structure of the electric vehicle, the driving motor andthe water pump motor are connected in parallel to drive the water pump of the electric vehicle, and the driving motor can directly drive the water pump to operate under most conditions when the driving motor is in an operating state, so that the load rate of the driving motor is increased, and the driving efficiency can be improved to a certain extent; when the driving motor is in a shutdown state, the water pump can be driven by the water pump motor to guarantee normal work of the water pump.

    本发明提供一种电动汽车水泵驱动结构、方法及电动汽车,驱动结构包括驱动电机、水泵电机以及水泵;驱动电机通过驱动轴与水泵传动连接,从而驱动水泵转动;水泵电机通过水泵电机轴与水泵传动连接,从而驱动水泵转动;驱动电机和水泵电机能够在电动汽车处于不同运行工况下相互切换,分别驱动水泵转动;采用以上技术方案,通过在电动汽车的水泵结构上设有驱动电机和水泵电机,并且驱动电机和水泵电机并联驱动电动汽车的水泵,在大部分情况下驱动电机处于运行状态时,可以由驱动电机直接驱动水泵运行,增加驱动电机的负荷率,一定程度上可以提高驱动效率;当驱动电机处于停机状态时,可以由水泵电机驱动,能够保证水泵的正常工作。
