Tech Tips

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.

PROCEDURE


  1. PRECAUTION

    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.

      Click here

    • When the cable is disconnected from the negative (-) auxiliary battery terminal, some systems need to be initialized after the cable is reconnected.

      Click here

    • If the HV battery has been struck or dropped, replace it.

    • When connecting a connector to the HV battery, confirm that the connector is securely connected through the following:

      - Push the connector until a click sound is heard.

      - Visually check and confirm that the connector is securely connected by pulling on it.

    • Make sure to insulate the high-voltage connectors and terminals of the HV battery with insulating tape after removing it.

      If the HV battery stored without insulating the connectors and terminals, electric shock or fire may result.

    • When performing repairs around the HV battery, such as using a tap, do not allow metal shavings to enter the HV battery.

    • Do not touch any high voltage wire harnesses, connectors or parts with bare hands.

    • B004TF3C01
      *1 No. 1 HV Battery Carrier Sheet

      Hold the areas shown in the illustration and lift the HV battery.

    • Do not break the No. 1 HV battery carrier sheet.

    • Do not allow foreign matter, such as grease or oil, to adhere to the bolts or nuts of the HV battery.

    • Do not put your hands into the openings of the HV battery.

    • When removing/installing/moving the HV battery assembly, make sure not to tilt it more than 80°.

    • Do not climb on top of or stand on the HV battery.

    • Do not allow any foreign matter or water to enter the HV battery.

    • If any bolts, nuts or clips are dropped into the HV battery, make sure to remove them.
