Abstract
The battery system has a current detection circuit, an amplifier, and a detection circuitthat detects the current flowing through batteriesfrom amplifieroutput. The current detection circuitis provided with a voltage source circuitthat supplies a test voltage to the input-side of the amplifier. Current detection linesconnect the current detection resistorto the input-side of the amplifier, and the detection circuitstores a reference voltage corresponding to the current detection linesin the connected state. When the voltage source circuitsupplies the test voltage to the input-side of the amplifier, the detection circuitcompares the amplifieroutput voltage with the reference voltage. The detection circuitdetects an open-circuit in the current detection linesby the shift in voltage from the reference voltage.
