KEY MODULES

The Basics of Electric Vehicle SImulations course is designed to give you a walk-through on how different EV components are engineered using Simulations. The course is split into 4 components. In each component, we will deal with one particular aspect of an Electric Vehicle. As you watch each  video, pay attention to the challenges and assignments that are provided as part of the course. These assignments will help you in applying the concepts that you would have learnt. At any point in time, if you have questions, do not hesitate to ask us. We hope you enjoy the course. The following 4 components are covered in this course.

  • Battery Thermal Management System
  • Electric Motor Design
  • DC-DC Converter Design
  • External Aerodynamics
