ABSTRACT:
The battery charge/discharge current detection apparatus has a power supply circuit powered by a battery mounted on a vehicle and configured to detect a charge/discharge current of the battery by use of a current detecting resistor connected between a negative terminal of the battery and a ground. The battery charge/discharge current detection apparatus includes a first function of detecting a voltage across the voltage detecting resistor, a second function of detecting a charge/discharge current of the battery on the basis of the voltage detected by the first function, a third function of detecting presence of an abnormality of the current detecting resistor, and a fourth function of informing an abnormality detected by the third function to the outside. The battery-side negative terminal of the power supply circuit is connected to the negative terminal of the battery.
