High-Voltage Lithium-ion Battery Diagnosis & Repair for Automotive Technicians

High-voltage lithium-ion batteries are no longer specialist components, they’re commonplace in modern workshops.

As EVs and plug-in hybrids roll through your doors more frequently, diagnosing and repairing their battery systems safely and competently is no longer optional – it’s essential.

High-Voltage Lithium-ion Battery Diagnosis & Repair is a 1-day technical training course designed for automotive professionals who need to confidently and safely test, diagnose, and carry out repair work on high-voltage lithium-ion battery systems. Whether you’re working with mild hybrids or full EVs, this course gives you the knowledge, skills, and mindset to handle the job correctly.

In this 1-day automotive course, participants will cover:

  • Safe working practices for high-voltage lithium-ion battery assembly, disassembly, and diagnosis
  • Understanding battery system design, construction, and internal modules
  • Diagnosing common faults, including imbalance and insulation issues
  • Interpreting battery management system (BMS) data for accurate fault identification
  • Using OEM procedures for high-voltage battery repairs
  • Voltage and insulation resistance testing techniques for live systems
  • Thermal runaway: understanding the risk and mitigating causes, recognising early warning signs, and response protocols
  • Arc flash and electric shock risks, and how to protect yourself and your team
  • PPE selection and use, including gloves, arc-flash protection, and insulated tooling
  • Charging and discharging procedures used during repair, including equipment types, limits, and monitoring
  • Module replacement and cell balancing considerations

IMI Certification

Upon successful completion of the course, delegates will receive an Our Virtual Academy LIVE certificate in High Voltage Lithium-ion Batteries Diagnosis & Repair.
