The invention discloses a charging load management method for a pulse charging method, and belongs to the field of lithium ion batteries. The method comprises a staggered sorting method for different charging pulses, a pulse current waveform adjusting method, a method for grouping and staggered sorting of a series of pulses with equal periods, a method for grouping and staggered sorting of a series of pulses with unequal periods and a method for overall coordination of the charging pulses. According to the method for grouping different pulses and sorting in time, the total charging current of all loads can be reduced on the premise that a single charging load is not reduced, and the fluctuation amplitude of the total charging current is reduced. When the method is applied to the battery pack consisting of a plurality of battery cells, the overall charging power fluctuation of the battery pack can be stabilized; when the method is applied to multiple electric vehicles, the charging power fluctuation of the electric vehicle charging station can be stabilized, the vehicle charging station is assisted to participate in the response of the power grid demand side, and the stability of the power grid is improved.

    一种面向脉冲充电法的充电负荷管理方法,属于锂离子电池领域,该方法包括:不同充电脉冲错开排序方法、脉冲电流波形调整方法、对一系列周期相等的脉冲分组和错开排序的方法、对一系列周期不相等的脉冲分组和错开排序的方法和对充电脉冲的统筹协调方法。所述对不同脉冲进行分组和在时间上进行排序的方法,可在不降低单个充电负荷的前提下降低所有负荷的充电总电流,并减小其波动幅度。将本发明的方法应用到由多个电芯组成的电池组中,可以平抑电池组总体的充电功率波动;将本发明的方法应用到多辆电动汽车上,可以平抑电动汽车充电站的充电功率波动,协助汽车充电站参与电网需求侧响应,有利于提升电网稳定性。
