Abstract

The invention provides a battery equalization control system and an energy storing device, and relates to the technical field of a battery pack control. The battery equalization control system is characterized in that the battery equalization control system is arranged between at least two battery cells, the battery equalization control system comprises a detector, a controller and a converter; afirst side battery cell, a second side battery cell and the detector form a detection loop; the first side battery cell, the second side battery cell and the converter form a conversion loop; the detector detects voltage values of the first side battery cell and the second side battery cell through the detection loop; and the controller determines whether a battery equalization condition is met ornot according to the voltage values of the first side battery cell and the second side battery cell, and controls the converter to perform voltage equalization between the two side battery cells of the first side battery cell and the second side battery cell after the battery equalization condition is met. The technical problems that in the prior art, an existing equalization scheme is only suitable for small capacity and low in efficiency are relieved.

Description

technical field [0001] The invention relates to the technical field of battery pack control, in particular to a battery balancing control system and an energy storage device. Background technique [0002] Lithium battery energy storage technology has a wide range of applications in the field of electric vehicles, and is also an important access solution for renewable energy such as wind energy and photovoltaic power generation. Due to the limitation of manufacturing process and raw materials, there are slight differences in the performance of individual cells in lithium battery packs, which will cause overshoot or overdischarge of single cells in charging and discharging applications, and in severe cases, irreversible damage will affect the battery pack. Therefore, it is necessary to use balanced control technology to manage the battery pack. [0003] Existing equalization schemes can be roughly divided into two aspects: passive equalization and active equalization. The pas...
