Abstract

A charging pile system for battery pack balance control includes electric power equipment, monitoring management workstation, transaction management system, distribution network, data network, charging equipment, power exchange equipment, monitoring equipment and battery pack balance control system, wherein, the battery pack balance control comprises an acquiring unit, a judging unit, an arithmetic unit, a control unit and a balance management unit. The battery pack equalization control system can equalize the batteries in the battery pack and prolong the battery life.

Description

technical field [0001] The invention belongs to the field of charging piles, and in particular relates to a charging pile system with balanced control of battery packs. Background technique [0002] The battery pack in an electric vehicle is composed of multiple battery cells. Each battery cell has inconsistencies during production and use. If it is not controlled, it will have a certain impact or even danger on the use of the battery. Its impact mainly reflects In the following aspects: (1) Since the batteries of the series battery pack are charged and discharged at the same time, the batteries with low capacity must be fully charged first during the charging process. For the sake of battery life and safety, the charging current will be disconnected at this time, and the battery pack is considered to be fully charged. This will cause the capacity of the battery pack to not be fully utilized, and the long-term deep charge and deep discharge of the low-capacity battery will ...
