Limit to Charge / Discharge Control Value by Hybrid Battery Temperature High

History of HV battery charge/discharge being restricted

If the temperature of the HV battery becomes approximately 44°C (111.2°F) or higher due to high ambient temperature, high cabin temperature, continuous driving under high load (such as mountain driving or frequent acceleration/deceleration), clogged hybrid battery intake duct, etc., the HV battery current will be restricted

In this case the value of WIN/WOUT will decrease and the engine will stop and start less frequently.

  1. If this Vehicle Control History item is stored, perform the following inspections.
    • Check the Vehicle Control History freeze frame data.
    • Check for clogs in the hybrid battery intake duct.
    • Inspect the HV battery cooling filter.

      2018 - 2024 MY Camry HV [07/2017 -        ]; HYBRID / BATTERY CONTROL: BATTERY COOLING FILTER: INSPECTION

    • Check the intake port of the HV battery cooling system for blockage, such as luggage, etc.
  2. After performing the above inspections, check the temperature of the HV battery in the Data List.

    If the temperature of the HV battery is high (approximately 44°C (111.2°F) or higher), stop the vehicle, turn the air conditioning system on (Temperature: Lo, Blower speed: Max) and perform the Active Test "Control the Hybrid Battery Cooling Fan". Check that the temperature of the HV battery decreases.

  3. This Vehicle Control History item may be stored if the temperature of the HV battery became high due to certain conditions, such as if the ambient temperature was high, cabin temperature was high or the vehicle was driven continuously under high load (such as mountain driving or frequent acceleration/deceleration).

    Explain to the customer that this is not a malfunction.
