About This Course:-

This course will be a first level course on electric vehicle. Students will be able tounderstand the operation of battery driven electric vehicle. The course will start withintroduction section which will enable the students to understand the focus areas thatcome under the umbrella of electric vehicles. Then the course will start covering this focusareas one by one such as vehicle dynamics, Motors, Power Electronics, Batteries,Charging etc. The most important part of this course will be that each topic will beanalyzed and demonstrated through Matlab Simulink, so that the grip of the subject willbe strong and the knowledge acquired will be useable in real time applications.

Course layout

Week 1  :  Introduction to Electric Vehicle
Week 2  :  Vehicle Dynamics: Modelling and Simulation
Week 3  :  Fundamental of Drives and DC Machine Modeling
Week 4  :  DC Machine Drives and Control of EV Using DC Machine

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of average of best 3 assignments out of the total 4 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100

Final score = Average assignment score + Exam score

YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.
