The invention provides a vehicle charging control method, a vehicle charging system and a vehicle. The vehicle charging control method comprises the steps that after a first charging port of a vehicle is connected with a first charging pile, first insulation detection voltage of the first charging port is obtained; and according to the magnitude relationship between the first insulation detection voltage and the highest allowable charging voltage of the vehicle, controlling a boost charging circuit to work, and performing boost conversion on the charging voltage provided by the first charging pile to charge the power battery, or the direct charging circuit is controlled to work to receive the charging voltage provided by the first charging pile to directly charge the power battery. According to the vehicle charging control method, any charging port in the vehicle charging system can be compatible with the high-voltage charging pile and the low-voltage charging pile.
本申请提供一种车辆充电控制方法、车辆充电系统和车辆。车辆充电控制方法包括:在车辆的第一充电口与第一充电桩连接后,获取第一充电口的第一绝缘检测电压;以及根据第一绝缘检测电压与车辆的最高允许充电电压之间的大小关系,控制升压充电电路工作而将第一充电桩提供的充电电压进行升压转换后对动力电池充电,或者控制直接充电电路工作而接收第一充电桩提供的充电电压直接对动力电池充电。所述车辆充电控制方法可以让车辆充电系统中的任一充电口都能够兼容高压充电桩和低压充电桩。
