EV Training – IMI Level 2.2 qualification

IMI Level 2.2 Award in Electric/Hybrid Vehicle Routine Maintenance Activities

Qualification ID No: 603/1466/7
Qualification duration: 2 days

This award is designed for vehicle mechanics and technicians who maintain and repair electric and hybrid electric vehicles.

It contains the knowledge and skills required to work safely around a vehicle’s high voltage electric drive train system and associated high and low voltage electrical systems whilst carrying out routine maintenance or repairs.

On completion of this qualification, candidates will have gained knowledge of both high and low voltage technologies and an understanding of their dangers.

The qualification content comprises classroom and workshop based support sessions designed to enable candidates to practice hands-on tasks and safety procedures that are required to be carried out when working on and around electric and hybrid vehicles.

To successfully complete the course and gain this IMI Level 2 award, candidates must sit and pass an online exam under exam conditions and carry out practical assessments for isolating and reinstating the vehicle’s high voltage system (making the vehicle safe) and connecting / disconnecting EVSE to charge the vehicle’s high voltage battery.
