A low-voltage circuit control method, which is applied to a power management unit (11) in a low-voltage circuit control system (10), comprises: when the current of a low-voltage loop is greater than a preset current, determining, on the basis of voltages at two ends of a power management unit, whether a fault point of a low-voltage circuit control system is located in a second low-voltage loop (14); then, when the fault point is not located in the second low-voltage loop, controlling a direct-current converter (12) to be turned off, and on the basis of the current of the low-voltage loop after the direct-current converter is turned off, determining a turned-on/turned-off state of the power management unit, such that at least the second low-voltage loop can work normally; and when the fault point is located in the second low-voltage loop, controlling the power management unit to be in the turned-off state, such that the first low-voltage loop (13) can work normally. A low-voltage circuit control apparatus, which is applied to a power management unit in a low-voltage circuit control system. An electronic device, which implements a low-voltage circuit control method. A computer-readable storage medium, wherein when stored computer execution instructions are executed by a processor of an electronic device, the electronic device can execute a low-voltage circuit control method. A low-voltage circuit control system, comprising a direct-current converter, a low-voltage circuit, and a power management unit for executing a low-voltage circuit control method. The low-voltage circuit control system consists of a single storage battery (141) and a single direct-current converter (12), and therefore the costs can be effectively reduced.
