Abstract
A system for charging a rechargeable battery supplies a current to the battery to charge the battery. The system determines a temperature associated with the battery and identifies a cutoff parameter based on the determined temperature. The system determines when the supplied current matches a value corresponding to the cutoff parameter and stops further supply of the supplied current to the battery when the supplied current matches the value corresponding to the current cutoff parameter.
