HV BATTERY RECOVERY INSPECTION

DTC Code DTC Name
RECOVERY INSPECTION

CAUTION / NOTICE / HINT

CAUTION:


  • When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.

  • Before returning the HV battery, make sure to perform a recovery inspection.

  • Accidents such as electric shock may result if the HV battery is disposed of improperly or abandoned.

    Therefore, make sure to return all HV batteries through an authorized collection agent.

  • To reduce the risk of fire, HV batteries must not be stored in an area where they will be exposed to fire or high temperatures.

  • If the temperature of the HV battery is high, leave it until the temperature drops.

Tech Tips

In order to return the HV battery in a safe manner, discharge it as necessary. By performing a recovery inspection, whether discharging the HV battery will be required or not and the discharge method can be checked.

PROCEDURE


  1. INSPECT FOR ELECTROLYTE LEAK

    CAUTION:

    Be sure to wear insulated gloves and protective goggles.


    1. B000T5X

      Position the HV battery as shown in the illustration and leave it for 5 minutes.

    2. Check that no electrolyte is leaking from the HV battery.

      OK
      There is no electrolyte leaking from the HV battery.

      CAUTION:


      • Perform this procedure in an area where the battery will not be exposed to fire.

      • Do not touch the HV battery, unless absolutely necessary, as electrolyte may be leaking.

      Note

      If there is an electrolyte leak, make sure to wear insulated gloves and goggles and clean it using a piece of cloth. Do not leave electrolyte-contaminated cloths unattended. Dispose of them according to law or local regulations.

  3. CHECK HV BATTERY VOLTAGE

    CAUTION:

    Wear insulated gloves.


    1. B000PXSC01
      *1 No. 1 HV Battery Main Cable (A)
      *2 No. 2 HV Battery Main Cable (B)

      Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Condition Specified Condition
      A - B Always Below 233.8 V

      CAUTION:

      Make sure not to cross the probes of the electrical tester.

  4. INSULATION INSPECTION OF HV BATTERY

    CAUTION:

    Wear insulated gloves.


    1. B000PUAC01
      *1 No. 1 HV Battery Main Cable (A)
      *2 No. 2 HV Battery Main Cable (B)
      *a Battery Outer Case

      Using a megohmmeter set to 500 V, measure the insulation resistance according to the value(s) in the table below.

      Note

      Be sure to set the megohmmeter to 500 V when performing this test. Using a setting higher than 500 V can result in damage to the component being inspected.

      Standard Resistance
      Tester Connection Condition Specified Condition
      A - Battery Outer Case Always 1 MΩ or higher
      B - Battery Outer Case Always 1 MΩ or higher

    CAUTION:

    Wear insulated gloves.


    1. Check that the HV battery is not deformed or damaged.

      OK
      The HV battery is not deformed or damaged.

  6. HV BATTERY CONNECTORS VISUAL CHECK

    CAUTION:

    Be sure to wear insulated gloves and protective goggles.


    1. Check that the orange connectors connected to the battery ECU assembly are not deformed or damaged.

      OK
      The connectors are not deformed or damaged.

      Tech Tips

      If any of the connectors are damaged, a Li-ion battery discharger will not be able to be connected to the HV battery. Soak the HV battery in a saltwater solution to discharge it.
