The invention discloses an electric vehicle, a power battery charging control method and device thereof and a storage medium, the electric vehicle comprises a three-phase inverter and a driving motor, and the three-phase inverter and the driving motor form a charging circuit. The direct-current charging pile charges a power battery through a charging circuit formed by a three-phase winding and a three-phase inverter of a driving motor, and the charging control method comprises the steps that firstly, charging parameters between the direct-current charging pile and the electric vehicle are obtained; and then, according to the charging parameters, a phase dislocation control mode or a same-direction control mode is determined to be adopted to control a three-phase inverter, so that the direct current charging pile can charge a power battery in the electric vehicle. Therefore, according to the charging control method of the power battery in the electric vehicle, the magnetic steel temperature rise of the motor can be reduced, the demagnetization risk of the motor can be avoided, meanwhile, the quality performance of the charging current can be optimized, the impact current of power supply equipment can be reduced, and the charging reliability and compatibility can be improved.

    本发明公开了一种电动车辆及其动力电池充电控制方法与装置、存储介质,其中,电动车辆包括三相逆变器和驱动电机,三相逆变器和驱动电机构成充电电路,直流充电桩通过驱动电机的三相绕组和三相逆变器构成的充电电路对动力电池进行充电,充电控制方法先获取直流充电桩与电动车辆之间的充电参数,然后根据该充电参数确定采用错相控制方式或者同向控制方式对三相逆变器进行控制,以使直流充电桩能够为电动车辆中的动力电池进行充电。由此,该实施例的电动车辆中动力电池的充电控制方法能够降低电机的磁钢温升,规避电机退磁风险,同时能够优化充电电流的品质性能,减少供电设备的冲击电流,提高充电可靠性和兼容性。
