DTC P0ABF-123: Hybrid Battery Pack Current Sensor Circuit; DTC P0AC1-123: Hybrid Battery Pack Current Sensor "A" Circuit Low; DTC P0AC2-123: Hybrid Battery Pack Current Sensor "A" Circuit High: Description
WARNING: This page is about a different variant/trim than selected.
- The battery current sensor, which is mounted on the positive cable side of the HV battery, detects the amperage that flows to and from the HV battery. The battery smart unit receives a voltage of between 0 and 5 V that is in proportion to the amperage flowing in the cable. This voltage goes into the IB terminal from the battery current sensor. A battery current sensor output voltage below 2.5 V indicates that the HV battery is being discharged, and a voltage above 2.5 V indicates that the HV battery is being charged. The hybrid vehicle control ECU determines the amount of either charge or discharge amperage that is being received by the HV battery based on the signals that are input to terminal IB of the battery smart unit from the battery smart unit. The hybrid vehicle control ECU also calculates the SOC (state of charge) of the HV battery based on the accumulated amperage.
