SHARE
This course is designed to provide participants with a comprehensive understanding of electric drive vehicles and their distinct differences from traditional vehicles with combustion engines. The training offers insights into the various powertrain configurations of electric vehicles, focusing on the operation, testing, and diagnostics needed for motor-generator systems. Participants will gain technical knowledge about the different types of EV direct current (DC) and alternating current (AC) converters and how these components operate within both high and low voltage systems. Key modules cover the intricate communication networks in electric vehicles that link various systems to the power management electronic control unit (ECU). The program includes hands-on procedures for detecting battery leaks in hybrid battery systems and managing high-voltage cables. Additionally, the curriculum addresses the nuances of EV charging protocols and troubleshooting. Completing this training is beneficial for those preparing for the ASE L3 certification test.
