The battery parameter information acquiring circuit 1 is used for acquiring current parameters of the battery to be charged, and the controller 2 controls the charging circuit 3 to charge the battery to be charged in a specific charging mode through the algorithm circuit 4.
As shown in fig. 2, the charging method of the charger 100 according to the first embodiment of the present invention is as follows: after the current parameter of the battery obtained by the battery parameter information obtaining circuit 1 and the current discharging parameter of the battery are calculated by the charging mode algorithm circuit 4, the controller 2 of the charging control circuit 10 controls the charging circuit 3 to output a specific charging mode to charge the battery according to the calculation result.
As shown in fig. 3, the charger according to the second embodiment of the present invention is different from the charger according to the first embodiment in that the algorithm circuit 4 is replaced with a charge mode switching circuit 5, and the other steps are the same.
