The invention provides a power management device, a vehicle, a method and a storage medium, the power management device is applied to the vehicle, the vehicle comprises a power battery, a first low-voltage load and a second low-voltage load, and the working voltage of the first low-voltage load is different from that of the second low-voltage load; the vehicle is provided with a plurality of areas, the device comprises a plurality of power management modules and a low-voltage power supply, and each power management module corresponds to one area; the input end of each power supply management module is connected with the power battery and is also connected with the low-voltage power supply, and the output end of each power supply management module is connected with the first low-voltage load and the second low-voltage load in the corresponding area. Working voltage can be provided for the first low-voltage load and the second low-voltage load in the corresponding area based on the power battery or the power supply, meanwhile, each power management module can supply power to the low-voltage load in the corresponding area nearby, and the setting cost of the power supply wire harness can be reduced.

    本公开提供了一种电源管理装置、车辆、方法及存储介质,应用于车辆,车辆包括动力电池,第一低压负载和第二低压负载,第一低压负载与第二低压负载的工作电压不同;车辆设置有多个区域,装置包括多个电源管理模块以及低压供电电源,每个电源管理模块对应一个区域;每个电源管理模块的输入端既与动力电池连接,还与低压供电电源连接,电源管理模块的输出端与对应区域内的第一低压负载和第二低压负载相连,如此,可以基于动力电池或者供电电源向对应区域内的第一低压负载和第二低压负载提供工作电压,同时,每个电源管理模块可以就近为对应区域内的低压负载供电,有利于减少供电线束的设置成本。
