Abstract:
The present invention concerns a method and apparatus for battery charging. The method comprises the steps of connecting a battery to a battery charging apparatus and supplying a voltage and current to the battery, wherein a constant voltage is supplied for an extended period of time. At the beginning of the constant voltage being supplied, the initial charging current being supplied to the battery is noted (Amp). During the period in which a constant voltage is supplied, the rate of change of the charging current supplied to the battery (dl/dt) is monitored. The method includes calculating the ratio: K=Amp/(dl/dt) during the period in which a constant voltage is supplied, and when K equals a preselected value, maintaining the charging current at the instant value for an extended period of time.

Claim (Index 3):
A method as claimed in  claim 2 , the method including the step of applying a constant current charge until the cell voltage in the battery reaches a set regulation voltage.
