Battery diagnostics and service boundaries
What owners can see, and what only HV technicians may do.
You'll learn
- Understand battery diagnostics and service boundaries
- Know which checks an owner can do and which need a professional
- Recognise warning signs early
Overview
Owners can watch range, charging speed and warning lights. Opening the pack, replacing modules or testing HV insulation is specialist work.
In depth
High voltage
Orange cables and parts carry high voltage that can kill. Only certified high-voltage technicians may work on them.
Technicians use isolation procedures, insulated gloves and rated meters, and confirm there is no voltage before any work.
Key takeaways
Remember this
- Owners monitor; technicians service.
- Pack work needs HV certification.
- See the Safety Academy for isolation steps.
