Free online courseHow do Eletric Vehicles works

Course Description

Electric vehicles are transforming the automotive industry, and technicians who understand how EV systems operate are becoming increasingly valuable. This free online course helps you connect the dots between the components inside an electric car and the real-world service questions that appear in workshops, inspections, and customer conversations. Instead of memorizing terms, you will build a clear mental model of how power is stored, managed, delivered to the motor, and safely controlled through high-voltage architecture.

You will explore the working principles behind EV operation, including what makes electric drivetrains different from combustion systems and why energy efficiency, torque delivery, and thermal limits shape performance. The course also clarifies the practical meaning of charging options, from slower everyday charging to rapid DC fast charging that can restore significant range in a short time. By understanding what each charging level is designed for, you will be able to make better decisions about use cases, installation considerations, and customer guidance.

A key part of modern EV reliability is the Battery Management System. You will learn the BMS’s primary role in monitoring and protecting the battery pack, keeping cells balanced, and supporting consistent performance over time. The course also explains how battery state information is estimated in practice, so you can interpret what State of Charge means, why it can vary, and how estimation methods influence diagnostics and user experience.

Because EV repair demands respect for high-voltage systems, the training introduces high-voltage concepts in a grounded, safety-focused way, including what voltage ranges are typically treated as high voltage in EV wiring. You will gain context that supports safer handling, clearer communication, and a more professional approach to troubleshooting.

Finally, you will look at advanced charging-related capabilities such as bidirectional charging, where an EV can send energy back to a home or the grid during high demand. By the end, you will have a stronger foundation for automotive repair pathways in the EV era and the confidence to keep learning from service documentation, tools, and future technical training.
