The invention discloses a charging and discharging management system and method for a series battery pack. The charging and discharging management system comprises a main control unit, a charging system and a detection system, the charging system comprises a single-pack charging circuit for independently charging each battery pack and a main pack charging circuit for charging the series main pack;the main control unit can control on and off of each single-pack charging circuit and the main-pack charging circuit; the detection system comprises a single-pack voltage sensor which is independently arranged for each battery pack and a total-pack voltage sensor which is arranged for a series total pack; and each voltage sensor is connected with the main control unit. According to the charging and discharging management system and method for the series battery pack, the main control unit, the charging system and the detection system are arranged; the main control unit can monitor charging and discharging data of each battery pack and the series main pack according to the detection system, and control the on-off of each charging circuit in the charging system according to the charging anddischarging data, so that each battery pack can be charged in a balanced manner and is safe in charging and discharging.

    本发明公开了一种串联电池包的充放电管理系统及方法,充放电管理系统包括主控单元、充电系统以及检测系统;充电系统包括针对每个电池包单独进行充电的单包充电线路以及对串联总包进行充电的总包充电线路;主控单元可控制每个单包充电线路以及总包充电线路的通、断;检测系统包括针对每个电池包单独设置的单包电压传感器以及针对串联总包设置的总包电压传感器;各电压传感器均连接主控单元。本发明的串联电池包的充放电管理系统及方法通过设置主控单元、充电系统以及检测系统,主控单元可根据检测系统监测各电池包及串联总包的充、放电数据,并据此控制充电系统中各充电线路的通、断,使得各电池包可均衡充电且充、放电安全。
