The embodiment of the invention provides a battery equalization method and device, equipment and a storage medium thereof. The method comprises the following steps: determining that the current battery parameter of a battery meets a preset battery equalization condition; and controlling on-off of a switch module in the power battery system based on the battery parameters so as to charge and discharge the batteries. By judging the battery equalization condition, charging and discharging between the batteries are controlled according to the battery state to perform battery equalization, the internal voltage balance of the batteries is improved, the power battery system is controlled to perform battery equalization to enter the next battery parallel operation after the difference value between the batteries is formed after other battery operations are finished, and the battery equalization efficiency is improved. And the occurrence probability of internal circulation of the batteries caused by parallel connection of the batteries and the occurrence probability of internal device damage are reduced.
本申请实施例提供一种电池均衡方法、装置、设备及其存储介质,方法包括确定电池当前的电池参数满足预设的电池均衡条件;基于电池参数控制动力电池系统中开关模块的通断以进行电池之间充放电。本申请通过判断电池均衡条件,根据电池状态控制电池之间充放电进行电池均衡,提高了电池内部电压平衡,在其它电池操作结束后形成电池之间的差值后,控制动力电池系统进行电池均衡进入下一项电池并联操作,降低了并联电池后造成的电池内部环流的发生几率以及内部器损坏的发生几率。
