Abstract
The power source apparatus has high-voltage-side power supply circuitrythat supplies driving batterypower to the first measurement circuitand the second measurement circuit, isolation circuitrythat isolates output from the first measurement circuitand the second measurement circuitand outputs it to the vehicle-side, and low-voltage-side power supply circuitrythat supplies vehicle auxiliary battery(12V) power to the isolation circuitry. The first measurement circuit, which is powered by the high-voltage-side power supply circuitry, outputs voltage signals to the vehicle-side via the first isolation circuitA, which is powered by the first low-voltage-side power supply circuitA, and the second measurement circuit, which is powered by the high-voltage-side power supply circuitry, outputs batteryerror signals to the vehicle-side via the second isolation circuitB, which is powered by the second low-voltage-side power supply circuitB.
