Description
図11は本発明の他の実施形態を示すフローチャートである。この実施形態は、充電に伴って上昇する電池電圧の最大値が所定寿命判別電圧以上か否かを検出することにより電池組2が寿命か否かを判別するようにしたものである。なお図11において、図2のフローチャートと同じかほぼ同じステップには同じステップ番号を付した。すなわち図2と同様にステップ108、120において電池電圧の最大値Vmを検出し、該最大電池電圧値Vmが寿命判別電圧値Vrα、Vrβより大きいか否かをステップ111、123が検出し、大きければステップ113でLED81を点灯させると共にステップ114で充電を停止させる。ステップ201、202は満充電を検出するステップで、例えば本出願人が先に出願した特願平4−156676号の如く、電池電圧の2階微分値が所定値以下になったことを検出して満充電とするΔ2V検出法によって検出するステップである。この実施形態によれば寿命電池組2を速やかに検出できるという効果を奏し得る。
Claims (1)
- 直列に接続された複数の素電池からなる電池組を充電する充電器において、
電池組の電池電圧を検出する電池電圧検出手段と、充電開始から所定時間経過した後の電池電圧に基づき電池組内の素電池数に対応した寿命判別基準電圧を設定し、電池電圧検出手段により検出された電池電圧が前記寿命判別電圧以上の時、電池組の寿命と判別する電池組寿命判別手段とを備えたことを特徴とする充電器。
