초록 ▼

A method of charging a rechargeable battery which comprises charging the battery with a charging current; sampling conditions of the battery during charging to recognize potential adverse conditions within the battery; interrupting the charging current periodically to create current-free periods and sampling an open circuit voltage of the battery during each current-free period to identify potential overcharge conditions in the battery; lowering the charging current if any adverse conditions are identified and continuing charging with the charging current if adverse charging conditions are not identified; and terminating charging when a predetermined value is recognized. The method of charging nickel-metal hydride and nickel-cadmium batteries is based on switching charging current as soon as temperature related battery open circuit voltage reaches the first predetermined value, tapering current and continuing charging up to terminating point.

대표청구항 ▼

[ What is claimed is:] [1.]1. A method of charging a rechargeable battery comprising:charging the battery with a charging current;sampling an open circuit voltage of the battery;lowering the charging current if the open circuit voltage reaches or exceeds a predetermined thermally dependant open circuit voltage (E.sub.Thermal); andcontinuing charging with the charging current until a predetermined charging condition is identified.
