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 Ford/Lincoln has to say.
Per Ford/Lincoln Workshop manuals ➤ General Information ➤ Service Information ➤ General Information ➤ Description And Operation ➤ High Voltage System Health and Safety Precautions - Overview: "WARNING: Service of the high voltage system on this vehicle is restricted to qualified personnel. The required qualifications vary by region. Always observe local laws and legislative directives regarding electric vehicle service. Failure to follow this instruction may result in serious personal injury or death."
Ford/Lincoln does not currently specify technician training levels and requirements for performing certain procedures, they only specify that qualified technicians can service HV vehicles.
Understanding high-voltage safety, including OEM-specific high-voltage technician levels, will help ensure a complete, safe, and quality repair.
