Abstract
A power supply apparatus has a battery apparatus that is composed of a battery, a temperature sensor that is thermally coupled to the battery and whose electrical resistance changes with the temperature of the battery to which it is thermally coupled, a temperature detection circuit that detects the temperature of the battery by detecting the electrical resistance of the temperature sensor, and a power supply circuit that feeds electrical power to the temperature detection circuit. The temperature sensor is connected via an overcurrent protection circuit to the power supply circuit.
