Beschreibung
Zusammenfassung:	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 c
