The invention provides a vehicle-mounted multi-motor direct-current charging system, a control method, a control device, equipment and a medium, the control method of the vehicle-mounted multi-motor direct-current charging system is applied to the vehicle-mounted multi-motor direct-current charging system which at least comprises two electric drives, and each electric drive is provided with a three-phase unit. When the vehicle-mounted multi-motor direct-current charging system is used for charging a vehicle battery, phase dislocation control is carried out on three-phase units among a plurality of electric drives, so that phase differences exist among the electric drives, in-phase control is carried out on the three-phase units in each electric drive, the peak value of an input current ripple is reduced through multi-electric-drive phase dislocation control, and thus the charging efficiency of the vehicle battery is improved. The external interference is reduced, and the use of the vehicle-mounted multi-motor direct current charging system is optimized.
本发明提供一种车载多电机直流充电系统、控制方法、装置、设备及介质,该车载多电机直流充电系统控制方法应用于至少包括两个电驱,每个电驱中设置有三相单元的车载多电机直流充电系统,包括,当用该车载多电机直流充电系统对车辆电池进行充电时,对多个电驱之间的三相单元进行错相控制,使多个电驱之间存在相位差,对每一个电驱中的三相单元进行同相控制,通过将多电驱错相控制减少输入电流纹波峰峰值,以减少对外干扰,优化该车载多电机直流充电系统的使用。
