The invention discloses a storage battery set flexible equalization charging and discharging management rectification module, a device and a system. The flexible equalization charging and discharging management rectification module comprises multi-stage DC power sources which are connected according to DC voltage magnitudes step by step and are distributed in a tree-shaped mode; for the multi-stage DC power sources, charging ends and discharging ends between two adjacent storage battery sets in same-stage DC power sources are connected correspondingly, so dynamic flexible equalization charging and discharging between the two adjacent storage battery sets can be realized. Through the technical scheme of the flexible equalization charging and discharging management rectification module, voltage consistency of each plumbic acid / lithium battery can be recovered to improve performance consistency of the storage battery set, and service life of storage batteries is improved.
Description
technical field [0001] The invention relates to the technical field of communication power supplies, in particular to a rectification module, device and system for flexible and balanced charging and discharging management of a battery pack. Background technique [0002] In my country, information technology (Information Technology, referred to as IT) equipment has been using uninterrupted power supply (uninterrupted power supply, referred to as UPS) power supply system. However, in recent years, with the rapid popularization of computer networks and the rapid development of data services, especially the rapid development of Internet Data Center (Internet Data Center, IDC) business, the reliability, safety and high consumption of traditional UPS power supply mode There are more and more problems emerging in terms of energy and other aspects. [0003] Using the high-voltage DC power supply system to supply power to IT equipment has become a new power supply mode for IDC equip...
