Diploma in Engineering Fundamentals of Electric Vehicles

We see more and more electric vehicles on our roads every day as they are four times more energy-efficient than combustion engine vehicles, which makes them more accessible and reliable, and they do not pollute the environment with CO2 emissions. The course opens by explaining how the flow of energy works by unpacking Ohm’s law to help you understand how electric energy travels through a circuit. You then encounter Kirchhoff's first two laws to understand both mass and energy conservation. These rules establish the flow of thermal and magnetic energies and their role in converting electrical energy into mechanical energy. This also covers the function of magnetic flux inside an electric motor.

This brings us to torque production inside an electric motor and commutation’s role in creating it. We explore a PMDC motor involving split rings and sliding carbon brushes for commutation to discover how it produces torque. We then investigate a permanent magnet synchronous motor (PMSM), which has higher torque, a smaller frame and no rotor current, making it the motor of choice for electric vehicles. As you navigate the PMSM, you will become familiar with three-phase circuits, the synchronous d-q frame theory and the ‘Park and Clarke transform’. This course teaches you the crucial methods involved in designing a field-oriented control and how to control the amplitude, phase and frequency of the voltage the battery provides to operate the motor.

We show you how to build a thermal profile for the motor using Norton's Theorem to demonstrate how heat flows and how you can improve resistances along the way. This thermal profile will help you judge whether or not the peak temperatures produced by your design will be within acceptable limits. This brings us to chargers as you see how chargers are designed and function. Special attention is given to public chargers, their design, the standards that govern them in different countries and how they communicate with the power grid and local energy operators. In some countries, the concept of ‘battery swapping’ is being legalized, which can make purchasing and operating an electric vehicle more accessible to drivers. We wrap up with an explanation of vehicle analytics and their role in guaranteeing the vehicle’s safety and ensuring the development of improved future models. This course is for anyone who is passionate about vehicle technology and wants to help the environment by gaining new engineering skills that will advance their career.
