DTC P0AC0-817: Hybrid Battery Pack Current Sensor Circuit Range / Performance [02/2014 - 11/2016]: Description

A battery current sensor is installed to the positive (+) cable 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 power management control ECU. The power management 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.
