Problems solved by technology

There are many equalization methods for this solution, but there are still problems. For example, trickle equalization will cause overcharge when there is a large difference between battery packs, while discharge equalization can only be used in an ideal state. Due to physical differences, it is difficult to achieve ideal balance. Even if the ideal balance is achieved, a new imbalance will be reached during the charging process

Abstract

The invention relates to a storage battery voltage balance management system. The storage battery voltage balance management system is characterized by comprising a charging unit, a plurality of single battery voltage balance units and a voltage balance management control unit, wherein the voltage balance management control unit is used for analyzing the voltage and current of single batteries of a storage battery monitored by the plurality of single battery voltage balance units and judging the voltage balance state of the storage battery so as to control the charging state, discharging state or pause state of the single batteries, thus finally realizing the balance of the voltage of the each section of the storage battery. According to the storage battery voltage balance management system, through the balance management control of the single batteries during charging and discharging of the storage battery, the single batteries of the storage battery are balanced, the overcharging and undercharging can be avoided, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of battery packs, and in particular relates to a battery pack voltage equalization management system. Background technique [0002] The appearance of the storage battery pack has opened up a new situation for the utilization of electric energy, got rid of the limitation of fixed power equipment, and is extremely convenient to use. However, electrical equipment that requires a large amount of electric energy often requires a battery pack to meet the demand. In the process of use, there is a problem of balance between the single cells in the battery pack, the main reason is the inconsistency between the single cells. At present, there are mainly the following methods to realize the equal charging of each single battery of the battery pack in series: [0003] 1. Add a parallel equalization circuit to each single battery of the battery pack to achieve the function of shunting. In this mode, when a battery is ...
