Abstract

The invention discloses a method and a device for managing a battery of a direct current power supply and relates to the technical field of system control, wherein the method for managing the battery of the direct current power supply comprises the following steps of: obtaining a power-off control parameter of the battery; confirming a power supply state of the direct current power supply according to the power-off control parameter; and controlling the battery of the direct current power supply according to the power supply state. According to the method provided by the invention, the mistaken judgment probability for system power-off control is reduced and the running stability of the power supply system is improved.

Description

technical field [0001] The invention relates to the technical field of system control, in particular to a battery management method and device for a DC power supply. Background technique [0002] Usually, in order to ensure the working stability and continuity of the power supply equipment, the power supply equipment is generally equipped with a backup power supply. Under normal conditions of the power supply system, the AC / DC output power of the power module is provided to the load. When the power module is powered off, it is powered by the battery. Therefore, battery management is an important function in DC power system control. [0003] With the development of DC power supply, the requirements for battery management functions are getting higher and higher and more detailed. A very important part of the battery management function is power-off control. The reliability of power-off control is the basis for ensuring the reliable operation of the DC power system and time...
