The invention discloses a battery pack connection module beneficial to balance control, and belongs to the technical field of power batteries, the battery pack connection module can realize balance control of battery cells and battery packs through energy transfer between the battery cells and the battery packs in the charging and discharging process of the battery packs. The continuous discharging or continuous charging time of different battery packs and different battery cells in the same battery pack is as close as possible, so that overcharging or excessive discharging of part of the battery packs is avoided, the charging efficiency and the battery utilization rate are improved, energy balance between the battery packs can be realized in the whole charging and discharging process, and the service life of the battery packs is prolonged. According to the energy storage system, the requirement for consistency among the multiple battery packs in the energy storage system is lowered, so that replacement is facilitated when the energy storage system has a local fault, maintenance cost is lowered, and meanwhile the effective service life of the battery packs can be prolonged through energy balance processing among the battery packs.

    本发明公开了一种有利于均衡控制的电池包连接模块,属于动力电池技术领域,该电池包连接模块能够在电池包充电与放电过程中,通过进行电芯之间以及电池包之间的能量转移,使不同的电池包以及同一电池包内不同的电芯的持续放电或者持续充电时间尽可能相近,从而避免部分电池包过充或放电过度,提升充电效率与电池利用率,整个充放电过程能够实现对电池包之间的能量均衡,降低对储能系统中多个电池包之间的一致性要求,从而有利于在储能系统出现局部故障时进行更换,有利于维护成本的降低,同时电池包之间的能量均衡处理还能够提升电池包的有效使用寿命。
