# Electric Vehicle Diagnostics
**Level:** Beginner to Intermediate
**Duration:** 20-40 Hours (Self-paced)
## Course Overview
Electric Vehicle (EV) Diagnostics focuses on identifying, analyzing, and resolving faults in electric vehicles using diagnostic tools, software, and electrical testing techniques. The course covers high-voltage safety, battery systems, electric motors, charging systems, power electronics, and communication networks.
> **Safety Note:** EVs contain high-voltage systems (often 400-800 volts or higher). Only trained and qualified personnel should perform work on energized high-voltage components. Always follow manufacturer procedures and use appropriate personal protective equipment (PPE).
