DESCRIPTION A battery current sensor is installed to the positive (+) terminal side of the HV battery and detects current flowing from the HV battery. The battery current sensor outputs voltage, which changes between 0 and 5 V according to the detected amperage, to the IB terminal of the battery voltage sensor. The battery voltage sensor sends signals to the hybrid vehicle control ECU. The hybrid vehicle control ECU determines the charging and discharging amount of the HV battery based on the received signals and calculates the SOC of the HV battery through the accumulated amperage.
MONITOR DESCRIPTION The hybrid vehicle control ECU detects malfunctions of the battery current sensor by monitoring motor and generator torque. If the hybrid vehicle control ECU detects a battery current sensor malfunction, the hybrid vehicle control ECU will illuminate the MIL and store a DTC. MONITOR STRATEGY
