PROBLEM TO BE SOLVED: To prevent a voltage of a battery from rising after shift from a constant current charge control to constant voltage charge control.SOLUTION: A charge current control device comprises: a voltage detection part 12 which detects a voltage of a battery 11; and a control part 15 which shifts from the constant current charge control to the constant voltage charge control when the voltage detected by the voltage detection part 12 reaches a target voltage. If the voltage detected by the voltage detection part 12 rises during the constant voltage charge control, the control part 15 enlarges a decrease width of a charge current.SELECTED DRAWING: Figure 1 |
