ABSTRACT:
The car power source apparatus is provided with a driving battery1that supplies power to the car's electric motor, a voltage detection circuit3that measures the voltage of batteries2in the driving battery1, a plurality of voltage detection lines8connected in parallel between the input-side of the voltage detection circuit3and driving battery1voltage detection nodes9, and a decision circuit6that determines if a voltage detection line8is open circuited from the voltage measured by the voltage detection circuit3. Each voltage detection line8has a voltage drop resistor10connected in series. The voltage detection circuit3is provided with input resistors13on its input-side. The car power source apparatus makes computations on the voltage measured by the voltage detection circuit3, which is from the voltage divider formed by the input resistor13and voltage drop resistors10, to detect voltage detection line8open circuit.
