Access Period: 30 days
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 course has been approved by the Accreditation Commission for Traffic Accident Reconstruction (ACTAR) for 2 Continuing Education Units (CEUs). Upon completion of this e-seminar, accredited reconstructionists should contact ACTAR, 800-809-3818, to request CEUs. As an ACTAR approved course, the fee for CEUs is reduced to $5.00.
This course also satisfies a requirement in the Accident Reconstruction Certificate Program.
