The invention provides a dual-motor controller for a hybrid power assembly of an electric vehicle and the electric vehicle, the power assembly comprises a generator power circuit, a motor power circuit and a control circuit, and the control circuit is used for controlling the motor power circuit or the motor power circuit to generate pulse alternating current on a direct current bus. The pulse alternating current is used for heating the power battery. And by controlling at least one bridge arm of the motor power circuit or the motor 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, so that the heating of the power battery is realized. In addition, 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 can be avoided, and the heating efficiency of the power battery is also improved.
本申请提供用于电动车辆混合动力总成的双电机控制器及电动车辆,动力总成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电机功率电路在直流母线上产生脉冲交流电,脉冲交流电用于加热动力电池。通过控制电动机功率电路或电机功率电路的至少一个桥臂,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,以实现动力电池的加热。由于母线电容也参与了充放电过程,从而能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,从而也提升了动力电池的加热效率。
