The embodiment of the invention provides a direct current voltage control method and device. The method comprises the following steps: in response to a direct-current power supply instruction, determining a current set direct-current discharge mode of a vehicle; based on the current set direct-current discharging mode of the vehicle, high-voltage direct current provided by a high-voltage storage battery of the vehicle is converted into first low-voltage direct current higher than the limit voltage or second low-voltage direct current lower than the limit voltage through a direct-current converter carried by the vehicle; wherein the second low-voltage direct current is used for starting the high-power electric equipment with the rated voltage.
本说明书实施例提供一种直流电压的控制方法及装置。所述方法包括:响应于直流供电指令,确定车辆当前设置的直流放电模式;基于所述车辆当前设置的直流放电模式,通过车辆搭载的直流转换器将车辆的高压蓄电池提供的高压直流电转换为高于额度电压的第一低压直流电或低于额度电压的第二低压直流电;其中,所述第二低压直流电用于启动所述额度电压的大功率用电设备。
