The invention discloses a whole vehicle power supply control method, device and equipment and a storage medium, and relates to the technical field of battery power supply, and the method comprises the steps that a sentry mode, a vehicle-mounted refrigerator mode, a vehicle working mode and a whole vehicle upgrading state recognized by a whole vehicle controller are obtained; determining a power supply mode of the direct current converter according to at least one of the sentry mode, the vehicle-mounted refrigerator mode, the vehicle working mode and the whole vehicle upgrading state; and controlling the direct-current converter according to the power supply mode, so that the direct-current converter supplies power through the power battery. The direct-current converter is directly connected with the battery pack and the low-voltage network of the whole vehicle and performs power supply control, so that the problem of realizing power supply of each low-voltage part of the whole vehicle in the state that the vehicle is not high-voltage and other high-voltage controllers are not awakened is solved, the power supply energy consumption is reduced, the power supply efficiency of the whole vehicle is improved, and power supply faults are reduced.

    本申请公开了一种整车供电控制方法、装置、设备及存储介质,涉及电池供电技术领域,本申请的方法包括:获取整车控制器识别的哨兵模式、车载冰箱模式、车辆工作模式以及整车升级状态;根据所述哨兵模式、所述车载冰箱模式、所述车辆工作模式以及所述整车升级状态中的至少一个确定所述直流变换器的供电模式;根据所述供电模式控制所述直流变换器,以使所述直流变换器通过所述动力电池进行供电。本申请通过直流变换器直接连线电池包及整车的低压网络并进行供电控制,解决了在车辆不上高压且不唤醒其余高压控制器的状态下,实现整车各低压部件供电的问题,降低了供电能耗、提升了整车供电效率、减少了供电故障。
