Powertrain Selection Methodologies – Mechanical

The automobile industry is growing rapidly and shifting towards Electric Vehicle. There is an immense need for skilled engineers in order to speed up this transition and meet the goals set by the companies. As compared to the traditional vehicle, which is driven by the internal combustion engine, the EV has a completely different architecture.

The aim of this course is to take you through the basics of the powertrain selection process. Where you gain a better understanding of the various forces acting on the vehicle. By the end of the program, you will be able to perform initial calculations and select a suitable motor for the required applications.

This course has been designed so that you are familiar with the most basic approach at various stages of powertrain calculations. The parameters to be considered and what should be avoided till the last? What other approaches could be considered in order to reach a specified goal?

Main Features – 

  1. Calculate aerodynamics of a given vehicle. 
  2. Understand wheel dynamics and parameters for wheel selection. 
  3. Perform the graphical study to determine the performance. 
  4. Select a suitable motor as per the performance requirements.

What is the Target Audience? 

  1. Undergraduate students 
  2. Post Graduation student
  3. Working professional
  4. Entrepreneurs are interested to gain knowledge of EV

Course Syllabus

Module Description
Basic Terminologies and Concepts In the first video, you will be introduced to the vehicle coordinate system and a few basic terms related to vehicle dynamics. Starting from the basics then we will move on to understand the various forces acting on an accelerating vehicle.
Aerodynamic Forces Aerodynamic force/drag force is the major force acting on a moving body. So it becomes really important to understand the factors governing the production of drag.

Using the most basic shapes of the geometry, study how the drag force is developed, various methods involved in order for drag reduction. How have these concepts led the design to evolve? Moreover, what are the tricks to calculate the drag force for any given 2 wheeler or 4 wheeler in consideration?

Case Study: Evolution of design and aerodynamic performance – Maruti 800, Alto 800, Swift Dzire and BMW i8.

Rolling Resistance Wheels are the most abused components in any vehicle. At any given moment numerous forces of various magnitude are acting on it, causing it to be one of the most stressed components. If you have the best motor in the world but there is no grip, how can you win? Thus it is important to choose an appropriate wheel for your vehicle because the wheel plays an important role in order to gain the control and traction of the vehicle.

Study about the various forces acting on the wheel, and its behavior under various load conditions. What is the right wheel to choose for your vehicle? How can you minimize the losses on the wheels? You will be able to answer all these questions by the end of this module.

Motor Selection Coming to the final module of this course. You will use the knowledge of the previous modules and the oldest tools – pen, and paper to go through the whole process in order to calculate the forces acting. You will plot graphs and study them in order to determine the performance of your vehicle at any given instance, during acceleration. By the end of it you will be able to determine the torque and rpm requirement at the wheels, and consecutively the power required.

But that is not enough, you will look at the performance output of various motors available in the market for EV application and decide on the motor to be used as per your requirement.
