Arc Flash & High Voltage Safety for Electrical Vehicles

The use of electric and hybrid vehicles is growing at a significant rate with objectives towards reducing carbon emissions and fuel/operating costs. It is estimated by 2040, 80 percent of the world’s city bus fleet will be electric, along with 33 percent of the world’s cars.

Lithium ion batteries are used extensively in electric and hybrid electric vehicles due to their high energy density and long cycle life. Increased energy density provides electric vehicles with extended range and increased power.

Modern electric vehicles have voltages that approach 1000 Volts. In addition to high voltage, short circuit current can deliver several thousand amps in large advanced battery systems. Also, components may retain a dangerous voltage even after the vehicle is switched off.

Service, repair, maintenance, and emergency response on electric vehicles can put workers at risk of electric shock and burns potentially resulting in serious injury or death.

Mechanics qualified in conventional automotive systems now require additional training, knowledge and skills including:

· Use of HV Personal Protection Equipment (PPE) and voltage rated insulated tools

· Zero Voltage Verification Procedures (de-energizing the system)

· Skills for servicing battery packs, auxiliary equipment, inverters, and traction motors

This one day course combines in-depth exploration of the workplace electrical safety standard, CSA Z462-21 with practical exercises on how to assess and mitigate hazards for anyone working on or near electrical equipment.

We use real life examples of electrical accidents to promote open discussion and analysis of the events ensuring maximum buy in from every student and conformance to company safe work practices and procedures.
