Isolate and re-energise high voltage systems in an electric vehicle
- Hybrid (HEV) - to include mild/micro hybrid vehicles where the voltage is considered dangerous.
- Plug-in Hybrid (PHEV)
- Extended Range Electric Vehicle (ER-EV) or Range Extended Electric Vehicle (RE-EV)
- Battery Electric Vehicle (BEV) or Pure Electric Vehicle (PEV)
- Fuel Cell Electric Vehicle (FCEV).
Warning: It has been recommended by industry experts that only those with suitable training and experience on working with electric vehicles should carry out the functions below.
You must be able to:
P8.1 injury to yourself and othersP8.2 damage to your working environmentP8.3 damage to other vehicle systems, components and unitsP9 Prepare, check and use all the appropriate test equipment following manufacturer's instructionsP10 Follow the manufacturer's recommendations to ensure residual voltage is within manufacturer's specification when isolating the high voltage system
P11 Use suitable testing methods to evaluate the performance of the re-energised high voltage system accurately, ensuring that it performs to the manufacturer’s operating specifications and legal requirementsP12 Refer any problems with the process to a relevant person in your workplaceP13 Ensure records are accurate, complete and passed to the relevant person(s) promptly in the format required.
