Hybrid vehicles typically have two sources of energy, an internal combustion engine using either diesel or petrol for fuel and a battery. The battery needs to be charged from the electricity supply network when the vehicle is not in use although some energy may be recovered during braking. Types of vehicle Electric vehiclesĮlectric vehicles use a large capacity battery and electric motor(s) to drive the vehicle. Having information specific to the manufacturer and the vehicle being worked on is important in identifying what actions are necessary to work safely. There are substantial differences in the designs of E&HVs from different manufacturers. They also store significant amounts of energy that can give rise to explosion if not dealt with correctly. This terminology is used in this guidance although high voltage is defined differently in other industry sectors.īattery systems may contain chemicals that can be harmful if released. For E&HVs dc voltages between Volts are referred to as 'high voltage'. In dry conditions, accidental contact with parts that are live at voltages above 110 Volts dc can be fatal.
Voltages present in E&HVs are significantly higher (currently up to 650 Volts direct current (dc)) than those used in other vehicles (12/24 Volts dc). They may also need to develop a wider range of skills and knowledge and have access to specialist tools and equipment in order to be able to work safely. People in the motor vehicle repair and recovery industry are now more likely to come across E&HVs and as a result need to be aware of the additional hazards they may be exposed to when working with these vehicles. This webpage is aimed at people working with these vehicles in the motor vehicle repair and roadside recovery industries and also the emergency services. The recovery, repair, and maintenance of these vehicles outside the manufacturers and franchised dealership networks is increasing. With the growth in environmental awareness, the use of electric and hybrid vehicles (E&HVs) is increasing.
