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.

    本发明公开了一种低压电源管理系统,属于汽车电源管理技术领域,其包括变压控制模块,分别与起动储能模块、备用储能模块及动力电池连接,用于将动力电池的高压转换成低压,为起动储能模块和备用储能模块进行补电;起动储能模块,用于为车辆控制器及低压负载提供电能;备用储能模块,用于在起动储能模块电量不足时为低压负载供电;储能监测模块,与起动储能模块连接,用于监测起动储能模块的状态,得到第一状态数据;电源控制模块,用于根据第一状态数据,控制车辆控制器及低压负载的电源分配。本发明通过增加冗余电源回路,能够避免因单一电源亏电而导致的车辆无法起动问题。
