The invention discloses a load balancing control method and power battery module balancing equipment, and relates to the technical field of power battery module balancing equipment. The load balancing control method comprises the following steps: when a power battery module is charged, combining a plurality of small-capacity power supply modules, and realizing load balancing of the power battery module by using a unified charging control signal among the power supply modules; and when the power battery module discharges, a two-stage discharge strategy is used for adjusting discharge current to form a plurality of discharge channels, and the plurality of discharge channels adopt a unified discharge control signal to realize consistency of the discharge current of each discharge channel. Through the embodiment of the invention, the load of each power supply module in the power battery module can be reasonably balanced, the balanced distribution of current on each power supply module is realized, and the balanced load distribution can improve the working efficiency of the power battery module to the maximum extent; meanwhile, the safety of the power battery system is improved, and the service life of the power battery module balancing equipment is prolonged.

    本发明公开一种负荷均衡控制方法及动力电池模组均衡设备,涉及动力电池模组均衡设备技术领域。所述负荷均衡控制方法包括:在动力电池模组充电时,使用多个小容量电源模块组合,各个电源模块之间使用统一的充电控制信号实现动力电池模组的负荷均衡;在动力电池模组放电时,使用两级放电策略调整放电电流,形成多个放电通道,多个放电通道采用统一放电控制信号实现各个放电通道的放电电流一致。通过本发明的实施例,可以合理地均衡动力电池模组中各个电源模块的负荷,实现电流在各个电源模块上的均衡分布,均衡的负荷分布可以最大化地提高动力电池模组的工作效率,同时提高动力电池系统的安全性和动力电池模组均衡设备的寿命。
