Over the past few years, we have seen more and more electric vehicles on our roads. Electric vehicles are four times more energy-efficient than combustion engine vehicles. They do not pollute the environment with CO2 emissions, which makes them more accessible and reliable than ever before. While we might not be ready to rid the world of carbon-based fuel completely, electric vehicles are a step in the right direction. Do you want to contribute to change while advancing your career? This course will start by teaching you how the flow of energy works. You will be introduced to Ohm’s law to help you understand how electric energy travels through a circuit. You will also learn about Kirchhoff's first and second law to understand both mass and energy conservation. These Laws will also help you understand how thermal and magnetic energy flow, convert electrical energy into mechanical energy, and the role of magnetic flux inside an electric motor.

Next, you will learn about torque production inside an electric motor and commutation’s role in producing torque. You will delve into a PMDC motor involving split rings and sliding carbon brushes for commutation to learn how torque is produced using this design. You will then investigate a PMSM motor, a permanent magnet synchronous motor, a motor with higher torque, smaller frame size, and no rotor current, making it the motor of choice for electric vehicles. As you explore the PMSM motor, you will be taught about three-phase circuits, the synchronous d-q frame theory, and Park and Clarke transform. The torque waveforms of PMSM motors need to be sinusoidal to perform well due to the windings’ construction. Therefore, the design of the controllers is crucial. In this course, you will learn how to design a field-oriented control, and you will understand how to control the amplitude, the phase, and the frequency of the voltage the battery provides to operate the motor.

Finally, you will learn how to build a thermal profile for the motor using Norton's theorem to understand how heat flows from the point it is produced outwards and how to improve the 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. The next topic of discussion will be chargers. You will discover how chargers are designed and how they work. Special attention will be given to public chargers, their design, the standards that govern chargers in different countries, and how chargers communicate with the power grid and the local energy operator. In some countries, the concept of “battery swapping” is being legalised by the authorities. Learn what battery swapping is and how this concept can make purchasing and operating an electric vehicle more accessible to drivers. Lastly, you will finish this course with an explanation of vehicle analytics, how it is done and why it is crucial to guarantee the vehicle’s safety and ensure better future models. Is vehicle technology your passion? Do you have a background in electrical or mechanical engineering? Do you work in the automotive industry? Take this engineering fundamentals course today, and gain the skills you need to start a career in electric vehicle technology.
