The invention relates to the technical field of battery management, in particular to an energy storage battery charging control method, which comprises the following steps: acquiring a battery temperature T1, a minimum charging temperature T0 of a battery, a battery residual capacity C, a charging pile output power Pu and a charging voltage U; if T1 is greater than T0, allowing the charging pile to charge the battery, and obtaining the heating power P1 of the battery when the battery is charged at the current temperature; obtaining the average electricity consumption power P0 when the BMS works within a preset time period before charging; re-estimating the electricity utilization power P2 of the BMS, and calculating the charging power Pm according to the Pu, the P2, the P1 and the P0; and estimating the charging time t = C/(Pm/U). The heating condition of the battery and the actual electricity utilization condition of the BMS in the charging process are comprehensively considered, the calculated charging power Pm better conforms to the actual condition, and the estimated charging time is more accurate.
本发明涉及电池管理技术领域,具体涉及一种储能电池充电控制方法,包括获取电池温度T1、电池的最低充电温度T0、电池剩余容量C、充电桩输出功率Pu和充电电压U;若T1大于T0,允许充电桩对电池充电,获取电池在当前温度下充电时的发热功率P1;获取充电前预设时间段内BMS工作时的平均用电功率P0;重新估算BMS的用电功率P2,并根据Pu,P2,P1和P0计算充电功率Pm;估算充电时间t=C/(Pm/U)。综合考虑了充电过程中电池的发热情况和BMS的实际用电情况,计算出的充电功率Pm更符合实际情况,估算出的充电时间也更加准确。
