    • An object of the present invention is to provide a charging equipment for a secondary battery that can charge any secondary battery, regardless of its kind, size and the like, until its charging rate comes to approximately 100%. The charging equipment comprises: a voltage increment device for incrementing a check voltage by a preset pitch of voltage from a lowest check voltage lower than a rated equilibrium voltage at full charge; a switch for switching applied voltage to the secondary battery to the special charging voltage or the check voltage supplied; a first judging means for judging whether an electric current detected by a current detection part is smaller than or as large as a preset standard electric current for judging; and a second judging means for judging whether the time required for the period from the last affirmative judgment to the present affirmative judgment is larger than two times as large as the time required for the period from the before-last affirmative judgment to the last affirmative judgment.
    • 本发明的目的是提供一种用于二次电池的充电设备,其可以对任何二次电池进行充电,而不管其种类,大小等,直到其充电率达到约100%为止。 所述充电设备包括:电压增量装置,用于在完全充电的情况下从低于额定平衡电压的最低检查电压增加预定间隔的电压; 用于将施加到二次电池的电压切换到特定充电电压或提供的检查电压的开关; 第一判断装置,用于判断由电流检测部检测到的电流是否小于或等于预设的用于判断的标准电流; 以及第二判断装置,用于判断从上次肯定判断到当前肯定判断的期间所需的时间是否大于从上次肯定判断到最后肯定判断期间所需的时间的两倍 。
