ABSTRACT:
A rechargeable battery charging circuit comprises a detection circuit for detecting the ambient temperature and a charging current control circuit for controlling the charging current in dependence upon the ambient temperature. The battery charging circuit charges the battery in response to the ambient temperature variations in order to maximize the charging efficiency of the battery at temperatures higher than room temperature.
