The invention provides a hybrid power assembly for an electric vehicle and the electric vehicle. The hybrid power assembly comprises a generator, a motor and a dual-motor controller, and the dual-motor controller comprises a generator power circuit, a motor power circuit and a control circuit; the control circuit is used for controlling the motor power circuit or the generator power circuit to generate pulse alternating current on the direct current bus. By controlling the motor power circuit or the generator power circuit, the discharging process of the power battery to the bus capacitor and the charging process of the bus capacitor to the power battery are alternately carried out, and when the charging process and the discharging process are alternately carried out, pulse alternating current can be generated on the direct-current bus, so that heating of the power battery is achieved. The bus capacitor also participates in the charging and discharging process, so that the problem that the heating speed is slowed down due to the fact that a large amount of current passes through the bus capacitor when the power battery is discharged and the current flowing through the power battery is reduced is solved, and the heating efficiency of the power battery is improved.

    本申请提供一种用于电动汽车的混合动力总成以及电动汽车,混合动力总成包括发电机、电动机和双电机控制器,双电机控制器包括发电机功率电路、电动机功率电路和控制电路;控制电路用于控制电动机功率电路或者发电机功率电路在直流母线上产生脉冲交流电。通过控制电动机功率电路或者发电机功率电路,使动力电池对母线电容的放电过程与母线电容对动力电池的充电过程交替进行,在充电过程与放电过程交替进行的时候,能在直流母线上产生脉冲交流电从而实现动力电池的加热。由于母线电容也参与了充放电过程,从而避免动力电池放电时有大量电流从母线电容经过使得流经动力电池的电流下降造成的加热速度变慢的问题,进而提升动力电池的加热效率。
