Method and device for charging secondary battery |
摘要 |
The invention provides a secondary battery charging method and device which can charge sufficient charge in a secondary battery adopting a nickel oxide as an electrode material for an anode, while minimizing the reduction in the cathode capacity of the secondary battery. <??>The secondary battery charging device comprises: charging voltage detecting means (14) for detecting the terminal voltage (Vch) of a secondary battery being charged; quadratic changing rate detecting means (16) for detecting the change( DELTA ( DELTA V)/ DELTA ( DELTA t)) in the changing rate of said terminal voltage (Vch); and charge ending means (25) for ending the charge when the change in said changing rate is lower than a predetermined reference changing rate (Vref). <IMAGE> |
