ABSTRACT:
The car power source apparatus is provided with a plurality of batteries, a temperature detection circuit, and an abnormal temperature rise prevention circuit. The temperature detection circuit detects electrical resistance change of a plurality of temperature sensors via a voltage conversion circuit, converts voltage conversion circuit output voltage into a digital signal via an A/D converter, and inputs that signal into a control circuit as a temperature signal. The abnormal temperature rise prevention circuit is provided with comparators to compare output voltage from the voltage conversion circuit of the temperature detection circuit with a reference voltage and output an abnormal temperature signal if battery temperature rises to a specified temperature, and a forced current cut-off circuit connected to the comparators to detect a comparator abnormal temperature signal and cut-off battery current. The control circuit and the abnormal temperature rise prevention circuit monitor battery temperature, and cut-off battery current.
