Discharge

WARNING: To conform with local laws, High Voltage Lithium Batteries must be discharged before packing for shipment. Additionally, HV batteries must be discharged before being put into storage. HV batteries to be shipped must have a State of Charge (SoC) of less than 30% or 50%, depending on the region. If the method of shipment is unknown or uncertain, or the battery is to be stored, it is recommended to discharge the HV battery to less than 30%.

WARNING: Do not ship or store an HV battery that has a loss of high voltage isolation. Verify HV battery isolation before packing for shipment or storage. Use the HV Battery Communication Tool, described in Toolbox article #41977, to determine if the HV battery parameters are within safe limits for shipment or storage.
Informational PurposesAn informational icon, calling your attention
Note
If possible, perform the discharge procedure before HV battery removal. This method requires less time and user interaction than to use the Battery Discharge Tool after the battery has been removed. The Battery Discharge Tool can only be used by certified technicians..
Informational PurposesAn informational icon, calling your attention
Note
The steps of the discharge procedure are mostly touch time, and can be performed by the Service Advisors/Front of House team as well as Service Technicians..
  1. For Front of House and Service Advisors
  2. Identify the vehicle SOC.
    • If the SOC is less than the specified values, proceed with removal. See Remove.
    • If the SOC is greater than the specified values, lower all of the vehicle windows and turn on the climate control system to maximum defrost. This setting will discharge the battery by approximately 10% SOC every hour.
  3. Move the vehicle to a location where it can safely continue to discharge the battery unattended.
  4. Identify the vehicle SOC every half-hour.
  5. When the SOC is below 50% for surface transport, or below 30% for air transport, turn off the climate control system, raise the windows, and then move the vehicle to the service bay.
  6. For Service Technicians
  7. Identify the vehicle SOC Max value.
    • If the SOC Max value is less than the specified values, proceed with removal. See Remove.
    • If the SOC Max value is greater than the specified values, continue to the next step.
  8. Move the vehicle to a location where it can safely discharge the battery unattended.
  9. Enable Service Mode Plus. See Service Mode Plus.
  10. On the vehicle touchscreen, touch Lightning Bolt icon > HV System.
  11. Touch Start HV Discharge, and then in the window that opens, touch Run.
    Informational PurposesAn informational icon, calling your attention
