The invention provides a vehicle power supply method and system and a vehicle, the method is applied to a vehicle power supply system, driving electric equipment comprises a plurality of driving electric appliances, and the driving electric appliances with rated power higher than a preset value are target driving electric appliances. The method comprises the following steps: acquiring an environment temperature and a use state of each target driving electric appliance; and when it is determined that the environment temperature is larger than or equal to the preset temperature and at least one use state is in an open state, the switching unit is controlled to be switched to the second power generation device to be connected with the driving electric equipment. According to the invention, the switching unit and the two power generation devices meet the power demands of the driving electric equipment and the household electrical appliance equipment, no extra high-voltage wire harness needs to be connected, and the cost of the motor home is reduced.

    本申请提供一种车辆供电方法、系统及车辆,该方法应用于车辆供电系统,所述行车用电设备包括多个行车用电器,多个所述行车用电器中额定功率高于预设值的为目标行车用电器,所述方法包括:获取环境温度及各目标行车用电器的使用状态;响应于确定所述环境温度大于或等于预设温度,且至少一所述使用状态为开启状态,则控制切换单元切换至所述第二发电装置与所述行车用电设备连接。本申请实现了通过切换单元和两台发电装置满足行车用电设备以及家用电器设备的用电需求,且无需额外连接高压线束,降低房车成本的效果。
