Abstract

A method of fast charging a rechargeable battery having a predetermined end-of-charge voltage, such as l lithium type battery is disclosed. The charging voltage can be expressed as a sum of the resistance free battery cell voltage and a voltage drop caused by the terminal resistance and by the internal resistance of the battery. During part of the charging process, the charging voltage is controlled so as to exceed the end-of-charge voltage, thereby allowing a high charging current. The voltage does not exceed the end-of-charge voltage. For batteries having a protection circuit, the voltage applied to the protection circuit during part of the charging process is preferably maintained above the end-of-charge voltage but below the protection circuit threshold voltage to avoid charging interrupting by the protection circuit. Also disclosed is a charging apparatus for controlling such a charging method, and a battery having information means for storing first and second maximum charging voltage parameters. The first and second maximum charging voltage parameters may be used by the charging apparatus for controlling the charging voltage according to the charging method of the invention.
