DESCRIPTION

A battery current sensor, which is mounted on the positive cable side of each HV battery junction block assembly, detects the current flowing to or from the battery pack. The battery current sensor sends a voltage, which varies between 0 and 5 V in proportion to the amperage, to the IB0 terminal of the battery ECU assembly. Similarly, it sends a voltage, which varies between 0 and 5 V in inverse proportion to the amperage, to the IB1 terminal of the battery ECU assembly. When the voltage at the IB0 terminal is below 2.8 V and the voltage at the IB1 terminal is above 2.2 V, this indicates that the HV battery is being discharged. Additionally, Meanwhile, when the voltage at of the IB0 terminal is above 2.8 V and the voltage at of the IB1 terminal is below 2.2 V, this indicates that the HV battery is being charged. The battery ECU assembly determines the charging and discharging amount of the HV battery based on the voltages input to the IB0 terminal and IB1 terminal and calculates the SOC of the HV battery through the accumulated amperage.

CONFIRMATION DRIVING PATTERN

Tech Tips

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click here


  1. Connect the GTS to the DLC3.

  2. Turn the power switch on (IG) and turn the GTS on.

  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

  4. Turn the power switch off and wait for 2 minutes or more.

  5. Turn the power switch on (IG) and turn the GTS on.

  6. With power switch on (IG) and wait for 5 seconds or more.

  7. Enter the following menus: Powertrain / HV Battery / Utility / All Readiness.

  8. Check the DTC judgment result.

    Tech Tips


    • If the judgment result shows NORMAL, the system is normal.

    • If the judgment result shows ABNORMAL, the system has a malfunction.

    • If the judgment result shows INCOMPLETE or N/A, perform driving pattern again.

CAUTION / NOTICE / HINT

CAUTION:


  • B004BJX

    Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.


    • Inspecting the high-voltage system

    • Disconnecting the low voltage connector of the inverter with converter assembly

    • Disconnecting the low voltage connector of the HV battery

  • B004C5R

    To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.

  • B0049VM

    After removing the service plug grip from the HV battery, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.

  • B004AZGC06
    *a Without waiting for 10 minutes

    After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.

    Click here

    Tech Tips

    Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly and the electric vehicle charger assembly.

Note

After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
