Warning

Only technicians who have been trained in High Voltage Awareness and have completed all required certification courses (if applicable) are permitted to perform this procedure. Proper personal protective equipment (PPE) and insulating HV gloves with a minimum rating of class 0 (1000V) must be worn at all times a high voltage cable, busbar, or fitting is handled. Refer to Tech Note TN-15-92-003, High Voltage Awareness Care Points for additional safety information.

Warning IconA warning icon, calling your attention to a possibly risky situation
CAUTION
If an HV Battery is to be shipped, such as returning a battery to MRB for refurbishment, the battery must have an SOC of less than 50% for land transport, or an SOC of less than 30% for air transport. If the SOC is greater than these values, the HV battery must be discharged to the acceptable values before the battery can be shipped.

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. Enable Service Mode Plus. See Service Mode Plus.
  2. Identify the vehicle's current SOC Max: In the Service Mode Plus menu, touch High Voltage > HV Battery, and then touch the large HV battery diagram to display the HV Battery information window.
    • If the SOC Max is less than the SOC shipping threshold, skip to the Remove section in this procedure.
    • If the SOC Max is greater than the SOC shipping threshold, continue to the next step.
  3. Move the vehicle to a location where the battery can be safely discharged unattended.
  4. In the Service Mode Plus menu, touch High Voltage > HV Battery.
  5. In the Tools section, touch Start HV Discharge, and then in the window that opens, touch Run.
    Informational PurposesAn informational icon, calling your attention
    Note
    The discharge routine starts and will automatically stop when the SOC Max value for surface transport has been attained.
  6. After discharge is complete, move the vehicle to the service bay.
