ABSTRACT:
A battery charger including a battery temperature monitoring device. The battery temperature monitoring device includes a first thermistor bonded to one of the terminals of the battery charger to provide a temperature signal of the temperature of the terminal, and a second thermistor positioned within the battery charger to provide a temperature signal of the ambient temperature. The temperature signals from both the first and second thermistors are applied to a temperature monitoring circuit that compares the temperature signals to a known discharge rate of an RC circuit. A microprocessor receives output signals from the temperature monitoring circuit and, using an algorithm, determines the actual temperature of the battery.
