The invention relates to a low-voltage circuit control method, device and equipment, a storage medium and a system, and relates to the technical field of vehicle control. The method is applied to a power management unit in a low-voltage circuit control system, and comprises the following steps: judging whether a fault point of the low-voltage circuit control system is located in a second low-voltage loop or not according to the voltage at the two ends of the power management unit under the condition that the current of the low-voltage loop is greater than a preset current. And then, under the condition that the fault point is not located in the second low-voltage loop, the direct-current converter is controlled to be disconnected, the on-off state of the power management unit is determined according to the current of the low-voltage loop after the direct-current converter is disconnected, and at least the second low-voltage loop can work normally. And when the fault point is located in the second low-voltage loop, the power management unit is controlled to be in the off state, so that the first low-voltage loop can work normally. Meanwhile, the low-voltage circuit control system is composed of a single storage battery and a single direct-current converter, so that the cost can be effectively reduced.

    本申请涉及一种低压电路控制方法、装置、设备、存储介质及系统,涉及车辆控制技术领域。该方法应用于低压电路控制系统中的电源管理单元,该方法包括:在低压回路的电流大于预设电流的情况下,根据电源管理单元两端的电压,判断低压电路控制系统的故障点是否位于第二低压回路中。之后,在故障点不位于第二低压回路中的情况下,控制直流转换器断开,并根据直流转换器断开后低压回路的电流,确定电源管理单元的通断状态,可以至少使得第二低压回路正常工作。在故障点位于第二低压回路中的情况下,控制电源管理单元处于断开状态,可以使得第一低压回路正常工作。同时,低压电路控制系统由单蓄电池和单直流转换器构成,能够有效降低成本。
