WTA’s High-Voltage and Electrical Systems Training Course for Electric Heavy-Duty Vehicles (EHDV) equips technicians with the knowledge and hands-on diagnostic skills needed to safely troubleshoot, service, and repair high-voltage and low-voltage systems on modern heavy-duty electric vehicles. This course builds on foundational electrical and safety concepts and introduces the advanced diagnostic practices required for high-voltage propulsion systems used in electric buses, trucks, and commercial fleet vehicles.

​

Technicians gain a comprehensive understanding of the architecture, operating principles, and interaction of high-voltage components, including traction motors, inverters, DC/DC converters, battery management systems, and auxiliary power circuits. Training emphasizes safe work practices, systematic fault isolation, and the testing procedures necessary to evaluate system performance under load.

​

This course is ideal for individuals pursuing a career as an EHDV technician, as well as service managers, fleet managers, and commercial vehicle inspectors responsible for supporting or overseeing electric heavy-duty fleet operations. Participants leave with the confidence to perform accurate diagnostics, identify failure points, and carry out safe, effective repairs that minimize downtime and extend vehicle reliability.
