The invention relates to a vehicle battery charging method and device, a vehicle and a medium. The method comprises the steps that whether a charging pile is matched with a power battery system of a current vehicle or not is judged; if the charging pile is not matched with the power battery system of the current vehicle, switching on the first switch, switching off the second switch, controlling a plurality of upper bridge arms of a first inverter of the first motor system and a plurality of upper bridge arms of a second inverter of the second motor system to be in a conducting state, and storing energy for inductors of a first motor and a second motor, meanwhile, power is supplied to the power battery; and after inductance energy storage of the first motor and the second motor is completed, multiple upper bridge arms of the first inverter are controlled to be in a disconnected state, multiple lower bridge arms of the first inverter are controlled to be in a connected state, and the power battery is charged. Therefore, the problem that charging cannot be carried out due to the fact that the voltage of the current charging pile is not matched with that of the vehicle power battery is solved, and the charging experience of the vehicle power battery is improved.
本发明涉及一种车辆的电池充电方法、装置、车辆及介质,包括:判断充电桩与当前车辆的动力电池系统是否匹配;若充电桩与当前车辆的动力电池系统不匹配,则闭合第一开关,断开第二开关,控制第一电机系统的第一逆变器的多个上桥臂和第二电机系统的第二逆变器的多个上桥臂均处于导通状态,为第一电机和第二电机的电感储能,同时为动力电池供电;在第一电机和第二电机的电感储能完毕后,控制第一逆变器的多个上桥臂处于断开状态,并控制第一逆变器的多个下桥臂处于导通状态,为动力电池充电。由此,解决了目前充电桩与车辆动力电池电压不匹配导致的无法充电的问题,提升了车辆动力电池的充电体验。
