The invention provides an extended-range electric vehicle power supply system. The system comprises a range extender, a high-power energy type power battery, a high-magnification type power battery, avehicle control unit, a power distribution unit, a driving motor controller, a driving motor and an energy recovery system. The range extender can charge a high-power energy type power battery through a vehicle-mounted charger; the driving motor controller can take electricity from the power distribution unit to supply power to the driving motor or charge the high-magnification power battery withthe electricity generated by the driving motor through the energy recovery system under a torque or power instruction of the vehicle control unit; and the range extender, the high-power energy type power battery and the high-magnification type power battery can be connected with the power distribution unit through high-voltage cables. The invention further provides a configuration method of the extended-range electric vehicle power supply system. On and off of the high-power energy type power battery, the high-magnification type power battery, the range extender and the driving motor controller can be determined under the torque or power instruction of the vehicle control unit.

    本发明提供了一种增程式电动汽车电源系统,包括增程器、高功率能量型动力电池、高倍率型动力电池、整车控制器、功率分配单元、驱动电机控制器、驱动电机和能量回收系统,增程器可通过车载充电机为高功率能量型动力电池充电,驱动电机控制器可在整车控制器的扭矩或功率指令下从功率分配单元取电给驱动电机或者将驱动电机产生的电通过能量回收系统给高倍率型动力电池充电,增程器、高功率能量型动力电池及高倍率型动力电池均可通过高压电缆与功率分配单元连接。本发明还提供了一种增程式电动汽车电源系统的配置方法。本发明可在整车控制器的扭矩或功率指令下决定高功率能量型动力电池、高倍率型动力电池、增程器与驱动电机控制器的通断。
