The invention provides a charging remaining time calculation method for a battery pack, and the charging process of the battery pack comprises the steps: carrying out the constant current charging mode of charging the battery pack for a first time at a constant current; and a constant voltage charging mode of charging the battery pack for a second time at a constant voltage equal to a cutoff voltage value after the voltage of the battery pack reaches the cutoff voltage, the method for calculating the remaining charging time of the battery pack comprising: determining whether the voltage of the battery pack reaches the cutoff voltage; and judging whether the voltage of the battery pack reaches cutoff voltage or not, and using different algorithms according to the judgment result. According to the method for calculating the remaining charging time of the battery pack provided by the invention, the estimated value of the remaining charging time is introduced, and the voltage of the battery pack, the power of the vehicle-mounted charger and the power consumption of other parts are comprehensively considered, so that the calculation accuracy can be ensured; in addition, the jumping phenomenon generated according to the current change in the charging remaining time calculation process can be prevented, and therefore the charging remaining time can be displayed more stably.

    本发明提供了一种电池包的充电剩余时间计算方法,其中,电池包的充电过程包括:对电池包以恒流充电第一时间的恒流充电模式;以及当电池包的电压达到截至电压后,对电池包以等于截至电压值的恒压充电第二时间的恒压充电模式,电池包的充电剩余时间计算方法包括:判断电池包的电压是否达到截至电压;以及判断电池包的电压是否达到截至电压,并且根据判断结果使用不同的算法。本发明提供的电池包的充电剩余时间计算方法通过引入充电剩余时间预估值,综合考虑了电池包电压、车载充电器功率及将其他部件的功耗,从而可以确保计算的准确性,并且还可以防止充电剩余时间计算过程中根据电流变化所发生的跳变现象,从而更加稳定地显示充电剩余时间。
