PROBLEM TO BE SOLVED: To suppress voltage increase of a battery after transition from constant current charge control to constant voltage charge control.SOLUTION: The charging current controller includes: a voltage detection part 12, for detecting a voltage of a battery 11; and a control part 15, transiting from constant current charge control to constant voltage charge control when a voltage V, detected with the voltage detection part 12 reaches a target voltage. The control part 15, when a charging current is being raised during the constant current charge control and the voltage V, detected with the voltage detection part, reaches a correction target voltage obtained by subtracting a predicted polarization voltage from the target voltage, increase in the charging current is stopped.SELECTED DRAWING: Figure 1

    【課題】定電流充電制御から定電圧充電制御への移行後における電池の電圧上昇を抑える。【解決手段】電池11の電圧を検出する電圧検出部12と、電圧検出部12により検出される電圧Vが、目標電圧に到達すると、定電流充電制御から定電圧充電制御に移行する制御部15とを備えて充電電流制御装置を構成し、制御部15は、定電流充電制御時において充電電流を上昇させているとき、電圧検出部により検出される電圧Vが、目標電圧から予測分極電圧を減算した補正目標電圧に到達すると、充電電流の上昇を停止させる。【選択図】図1
