HYBRID BATTERY SYSTEM


  1. OUTLINE


    1. The HV battery has high power and density, light weight and long life characteristics, compensates the vehicle drive energy and stores regenerative energy.

    2. The HV battery is positioned under the rear seats and optimally placed in order to ensure luggage room capacity.

    3. A service plug grip is provided to shut off the internal circuit of the battery.

    4. Due to a battery voltage sensor that monitors the HV battery condition (battery voltage, battery current value, temperature) and controls the charging and discharging amount to maintain a certain charging condition, charging from external sources is generally not necessary.

    5. An air cooling type system via the battery cooling blower assemblies is used and the intake air ducts and coolant ducts, etc., have been optimized in the HV battery cooling system to achieve enhanced cooling performance and noise reduction.

  3. PRECAUTION


    1. HV battery electrolyte is a highly alkaline potassium hydroxide solution (odorless, transparent, colorless). Careless handling of the HV battery is very dangerous. Handle the HV battery properly in accordance with the procedures below:

      Procedure Precaution
      When there is liquid leakage present in the area of the HV battery Neutralize it with a saturated mixture of boric acid and water.
      After litmus paper has been used to determine that the mixture is neutral, wipe it up with cloth.
      When battery electrolyte gets on skin, eyes etc.* Flush it with a saturated solution of boric acid and water, or with a large amount of water.
      Remove contaminated clothes at once.
      When a vehicle is scrapped Remove the HV battery from the vehicle for collection via the specified route.
      When stored The battery should not be left in a damp or wet location.
      When a vehicle is stored for a long time. Disconnect the auxiliary battery negative terminal.

      When in storage, the HV battery should be charged every 2 months to prevent HV battery discharge or damage. Using the following procedure, charge the HV battery with the vehicle.


      1. Connect the negative terminal of the auxiliary battery.

      2. Turn the power switch to ON for 3 minutes, do not apply any electrical loads. (This operation is needed to allow the hybrid vehicle control ECU to detect the correct SOC.)

      3. Enter the READY-ON state. After the engine starts, leave it running for 30 minutes to charge the HV battery.

      If the engine does not start or intermittently stops within 30 minutes, stop the operation at that time. (The HV battery does not need to be charged.)

      • *: If you get electrolyte in your eyes, call for help, do not rub your eyes. Rinse your eyes with a large amount of water and seek medical attention immediately.
