Overview

IMI Level 4 Award in the Diagnosis, Testing and Repair of Electric/Hybrid Vehicles & Components

This programme is designed for technicians who maintain and repair electric & hybrid high-voltage vehicle systems and components. The purpose of this programme is to provide technicians working on electric & hybrid vehicles with the required level of skills and knowledge to carry out repairs on live, high-voltage vehicle electrical components and systems safely.

The course is run over 3 days. Remit run the course for an additional day compared to other training providers so we can dive deeper, and further underpin safety principles and practices for working around live systems.

On completion, technicians will be able to practically demonstrate that they have the skills required to repair high-voltage vehicle electrical components and systems.

What’s Covered…

• Working safely on and around de-energised high-voltage systems and components
• The correct tooling and equipment to use for working on HV systems
• Electrical principles relating to low and high voltage vehicle systems
• Hazards associated with working on live high voltage vehicle systems and to reduce the risks to yourself and others
• In depth look at the charging systems and leads
• High voltage (HV) vehicle systems and components (HV Battery, Invertor, Charging systems including DC TO DC charging and plug in charging systems)
• Carrying out repairs on live high voltage vehicle systems safely
• The removal and strip down of the HV battery removing modules and Bus bar followed by rebuilding and balancing battery when refitted
• Differences between Alternating Current (AC); Direct Current (DC) and Three Phase current
• Technical Maths recap
• Calculating current, resistance, voltage and power in series and parallel circuits using Ohm’s Law
• Reading and interpreting circuit diagrams and how to follow current paths through a circuit Identifying the relevant manufacturer’s repair procedures associated with working on high voltage vehicle systems
• Energy flows during operation of the hybrid system in various mode

Remit will also…

Inb addition to the IMI Level 4 course material, Remit can also alter the course to be lighter or heavier on certain content depending on employees and their working involvement on certain systems. We can alter material on:

• High-voltage relay contactors testing
• Insulation testing High-voltage cables using mega-ohm meters
• Testing & Analysis using diagnostic equipment
• Component removal and inspection of vehicle components on-bench including High-voltage battery pack removal, strip replacement and bus-bar
• Different manufacturers and builds
• MG & MG2 phases checked using Milli-ohm meter
