|What Does the P0AC1 Code Mean?

The battery current sensor, which is mounted on the positive cable side of the HV battery assembly, detects the amperage that flows into the HV battery. The battery smart unit inputs a voltage, which varies between 0 and 5 V in proportion to the amperage, into the IB terminal from the battery current sensor. An output voltage of the battery current sensor below 2.5 V indicates that the HV battery is being discharged, and above 2.5 V indicates that the HV battery is being charged. The power management control ECU determines the charging and discharging amperage of the HV battery based on the
