As electric-only, hybrid, and fuel cell electric vehicles are increasing in sales, they are becoming more commonplace in repair facilities. Along with the unique powertrains that come with these vehicles, also comes unique safety concerns. Regardless of vehicle maker, high-voltage (HV) systems pose a threat of injury or death if not handled properly. Only personnel with the proper training, PPE, tools, equipment, and service information should perform work on the HV systems.
Many OEMs have specific training requirements for different levels of high-voltage technicians. Typically, these levels range from no interaction with any high-voltage part of the vehicle (even after the high-voltage battery is disconnected/isolated), to the ability to work on the vehicle under live conditions at the highest OEM HV education level you can earn. The number of levels in between these two ends varies by OEM. Always check the OEM requirements before attempting to disable an HV system. Let’s see what Hyundai has to say.
Hyundai does not currently specify technician levels and requirements for performing certain procedures in the vehicle specific service manuals. Hyundai does, however, give detailed warnings throughout service manuals, especially in the high-voltage disable procedure.
Hyundai gives a detailed list of required personal protective equipment needed when working on a HV vehicle. This list is found in the vehicle-specific service manual (SHOP) under General Information ➤ General Safety Information and Caution.
Per Hyundai Shop manuals, General Safety Information and Caution document: "Never allow technician to work on high voltage systems who are not wearing personal protective equipment. High voltage components should be covered with an insulation sheet to prevent safety accidents."
Understanding high-voltage safety, including OEM-specific high-voltage technician levels, will help ensure a complete, safe, and quality repair.
