Abstract
A temperature sensor avoids battery charger over-heating when rechargeable batteries arc charged In succession. The battery charger is provided with a control means having a voltage detection section and a control circuit. The control circuit stops charging when a rechargeable battery reaches full charge. The control means also has a temperature sensor to determine the temperature of heat producing elements in the power supply circuit. Charging current is reduced when the temperature of heat generating elements exceeds a specified temperature. Full charge detection is suspended when charging current is reduced to avoid false detection.
