The invention provides an extended-range dual-motor controller, an extended-range hybrid power assembly and an electric vehicle, and the extended-range dual-motor controller comprises a housing used for accommodating a power circuit and a DC protection switch, and the housing comprises a high-voltage DC port. The driving motor power circuit is used for receiving direct current from a high-voltage direct current port through the direct current protection switch. The generator power circuit is used for receiving alternating current generated by the generator and outputting direct current to a high-voltage direct current port through the direct current protection switch. And the direct current protection switch is used for connecting or disconnecting the driving motor power circuit and the generator power circuit with a high-voltage direct current port. The direct-current protection switch is switched off, so that faults of other loads hung on the direct-current bus can be prevented from spreading into the extended-range dual-motor controller, and power devices in the extended-range dual-motor controller are protected.
本申请提供了一种增程式双电机控制器、增程式混合动力总成和电动车辆,增程式双电机控制器包括用于容纳功率电路和直流保护开关的壳体,壳体包括一个高压直流端口。驱动电机功率电路用于通过直流保护开关接收来自一个高压直流端口的直流电。发电机功率电路用于接收发电机产生的交流电并通过直流保护开关向一个高压直流端口输出直流电。直流保护开关用于导通或断开驱动电机功率电路和发电机功率电路与一个高压直流端口之间的连接。断开直流保护开关可以避免直流母线上挂接的其他负载发生的故障扩散到增程式双电机控制器内部,保护增程式双电机控制器中的功率器件。
