The invention discloses a low-voltage power supply management system, which belongs to the technical field of automobile power supply management, and comprises a voltage transformation control module which is respectively connected with a starting energy storage module, a standby energy storage module and a power battery and is used for converting high voltage of the power battery into low voltage and charging the starting energy storage module and the standby energy storage module; the starting energy storage module is used for providing electric energy for a vehicle controller and a low-voltage load; the standby energy storage module is used for supplying power to the low-voltage load when the starting energy storage module is insufficient in electric quantity; the energy storage monitoring module is connected with the starting energy storage module and used for monitoring the state of the starting energy storage module to obtain first state data; and the power supply control module is used for controlling power supply distribution of the vehicle controller and the low-voltage load according to the first state data. By adding the redundant power supply loop, the problem that the vehicle cannot be started due to power shortage of a single power supply can be avoided.
