Abstract

The invention provides a distributed storage battery equalization apparatus and method capable of realizing both active equalization and passive equalization. The distributed storage battery equalization apparatus comprises a main controller and a plurality of monitoring terminals separately connected with the main controller, wherein the main controller comprises a first control unit and a first communication unit; each of the monitoring terminal comprises a second control unit, a second communication unit, a detection unit and an equalization unit; each detection unit is used for detecting the performance parameters of each battery cell in a corresponding battery group; and the first control unit controls a corresponding monitoring terminal to execute passive equalization operation when the average state-of-charge of any battery group is lower than a first preset value and controls a corresponding monitoring terminal to execute active equalization operation when the state-of-charge of any battery cell is lower than the average state-of-charge of a corresponding battery group. In virtue of the structure of the main controller and the plurality of monitoring terminals, the equalization apparatus is safer in structure, more convenient to install and more effective in equalization.

Description

technical field [0001] The invention relates to the field of storage battery management and maintenance, and more specifically, relates to a storage battery equalization device and method with both active equalization and passive equalization. Background technique [0002] Large battery packs have very extensive and important applications in fields such as electric power and communications. For example, the operating power supply of the power system substation, the power supply of the base station communication equipment, the uninterruptible power supply system (UPS) of the data center, etc., all use a large number of battery packs as the power supply of the backup power system and the DC system. Especially in the backup power system or the DC power system of the communication base station, it is necessary to use multiple sets of batteries, and each set of batteries has 54 to hundreds of batteries. [0003] Due to the objective differences between the single cells caused by...
