Basic Hybrid and Electric Vehicle Safety Webinar
I.D. # C0904 Duration 2 Hours
High-voltage, high-current energy storage systems and electrical circuits in many current and future alternative-propulsion powertrains present unique challenges to the automotive industry. Care must be taken to minimize risk to all who come into contact with the vehicle throughout its development and life cycle, including powertrain developers, assembly line workers, service technicians, vehicle occupants, and first responders. Significant risk to life and limb can arise from technical issues surrounding these vehicles.

This 120-minute webinar reviews safety concerns and precautions related to high-voltage circuits present in hybrid, plug-in hybrid, electric, and fuel cell hybrid vehicles. HV circuits are discussed in general to provide an understanding of "where the risk lies". The effects of electrical current on the human body are summarized and existing protective measures, along with the standards that govern such measures, are described. Specific issues related to vehicle development, service, and operation are explained, along with onboard fault detection systems used to protect individuals from electrical injury. A general understanding of electrical and mechanical engineering is helpful, but is not required.
Learning Objectives
  • Describe component functions and locations in a typical high-voltage powertrain as well as the onboard safety systems associated with such components
  • Explain the general effects of electric current on the human body
  • Know which national and international safety standards apply to high-voltage vehicle circuits
  • Summarize HV safety working issues that may be present during a vehicle's development, assembly, service, and operation
  • Identify general issues associated with extrication of occupants from vehicles with high-voltage powertrains
Who Should Attend
Light and heavy duty engineers and technicians who work directly with high-voltage vehicle circuits in hybrid, plug-in hybrid electric, and/or fuel cell hybrid vehicles, as well as component suppliers, safety officers and/or personnel who plan to develop high-voltage safety programs or procedures, will benefit from this webinar.
