The invention discloses a control method and device of a power management system, a storage medium and a processor. The method comprises the steps that a power-off instruction of a target vehicle is received, the power-off instruction is used for controlling a power management system to execute preset power-off operation, and the preset power-off operation comprises at least one of the following operations: controlling a first DCDC converter to be turned off and controlling a second DCDC converter to be turned off; the temperature of the environment where the target vehicle is located and the power consumption of at least two low-voltage storage batteries are obtained, and the at least two low-voltage storage batteries are arranged in parallel; detecting first working condition information of the low-voltage storage battery before current power-off, wherein the first working condition information comprises at least one of a non-fault state and a fault state; and based on the environment temperature and the first working condition information of the low-voltage storage battery, generating a power supply instruction which is used for controlling a power supply management system to supply power to the low-voltage storage battery. According to the invention, the technical problem of low-voltage storage battery feed is solved.

    本发明公开了一种电源管理系统的控制方法、装置、存储介质及处理器。其中,该方法包括:接收目标车辆的下电指令,其中,下电指令用于控制电源管理系统执行预置下电操作,预置下电操作包括如下至少之一:控制第一DCDC转换器关闭、控制第二DCDC转换器关闭;获取目标车辆所处的环境温度、低压蓄电池的耗电量,低压蓄电池为至少两个,至少两个低压蓄电池并联地设置;检测低压蓄电池在本次下电之前的第一工况信息,第一工况信息包括如下至少之一:非故障状态、故障状态;基于环境温度以及所述低压蓄电池的第一工况信息,生成补电指令,补电指令用于控制电源管理系统为低压蓄电池进行补电。本发明解决了低压蓄电池馈电的技术问题。
