VR27c - IVR L3 Electric/Hybrid Vehicles – High Voltage Isolation

VR27c covers the vehicle recovery technician’s considerations when handling and storing these types of vehicle and covers the isolation/reinstatement of the high voltage system in order to remove a component part.  It is aimed at heavy recovery technicians, especially those who remove commercial vehicles (including buses) that require isolation, where there is not a better way to stop the generation of power, as a result of the wheels turning but will suit any situation where isolation of the high voltage system is required. It is not for general, light vehicle recovery.

Key Learning Outcomes

• Health and safety requirements applicable to electric and hybrid vehicles

• Differences between internal combustion and high voltage vehicles

• The principles of hybrid and electric vehicle operation

• The potential hazards with high voltage vehicles

• Understand realistic vehicle recovery operator issues, including storage

Practical Learning Outcome

• Explain a low voltage disconnect and low voltage boost start, thermal checking and recording

• Demonstrate isolation/reinstatement of the high voltage system in order to remove a component part
