PURPOSE:To make the built-up of cell charging voltage at the time of full charging as well as to detect a voltage variation at the time of the full charging so easily and accurately, by constituting the uncharged capacity of an anode in a discharged state to be smaller that the uncharged capacity of a cathode. CONSTITUTION:The uncharged capacity of an anode at a discharged state is constituted to be smaller in substance than the uncharged capacity of a cathode, and at the time of charging, the anode is full charged earlier than the cathode. Therefore, a variation in cell charging voltage at the time of full charging is made larger by the large build-up of the anode to hydrogen generating potentional. With this constitution, such charging control as utilizing the voltage variation is made performable easily and accurately so that constant current-constant voltage charging can be done. |
