High-Voltage Handling And Storage Considerations: General Motors

High-voltage (HV) vehicles have some special considerations for handling and storing HV batteries and other components. The dangers of HV batteries are potential even after removal which is why certain precautions are needed. Let’s see what General Motors (GM) has to say.

GM has information pertaining to HV systems storage and handling when performing a repair. For example, the information can be found in the 2023 Chevrolet Bolt EV service manual under: Engine/Propulsion ➤ Hybrid/EV Energy Storage ➤ Repair Instructions ➤ High Voltage System Inspection.

If a battery needs to be shipped, GM provides the information located under: Engine/Propulsion ➤ Hybrid/EV Energy Storage ➤ Repair Instructions ➤ Drive Motor Battery Replacement And Shipping Preparation.

In these two documents, GM provides information on vehicle isolation, personal protection equipment (PPE), special tools, state of charge and other considerations for storage, and handling of HV parts.

All precautions, including placards and personal protective equipment must be observed when performing repairs on HV vehicles. Make sure to utilize GM repair information prior to beginning any repairs.
