Powertrain Selection Process – Electrical

Category:

EV Powertrain

For the last century, our world has run majorly on internal combustion engines. The enormous consumption of resources has led to a decrease in global fossil reserves at an alarming rate. This has led to the coming of alternative energy sources, as a result, the automobile industry is also undergoing change. Electric Vehicles are back after a century.

The aim of this course is to take you through the basics of the electric powertrain selection process. Where you gain a better understanding of the electric architecture of the powertrain. By the end of the course, you will be able to select a suitable component for your EV. This course is designed so that you are able to find solutions to problems like – which motor to choose? What is the size of the battery pack required? Which type of controller should one use? What is the type of cell and how to control them?

Main Features –

Course Syllabus

Module	Description
Motor Basics	In this module take a brief look into the history of the electric vehicle, and its development over the years. What are the different types of architectures? Further, have a basic understanding of motor types used in EV and the basic working principle of a motor.
Motor Characteristics	Now that, the types of motors and basic working principle is clear. Take a look at the construction, working and various characteristics of the DC Series motor, Induction Motor and BLDC motor. By the end of the module, you will be able to choose the type of motor required as per the application.
Motor Control Methods	Now that the motor characteristics and behaviour is clear, this module will tell you about how the motor characteristics can be controlled as per the requirements and components involved for the same.
Motor Calculation	In this short module, you will learn about how to determine the motor power required and the input requirements for the motor, in order to finally select the motor for your requirement.
Li-Ion Battery Pack Selection	The previous modules were all about the motor and its control, but the energy required by the motor is stored in the battery pack. This module starts with the question – despite having so many chemistries, why only Lithium-Ion cells are being preferred? This is then followed by a basic introduction to the battery pack – cell arrangement and design parameters. And by the end, you will be able to calculate the battery pack size required.
BMS and Safety	Now the battery pack is calculated and it is known what kind of cells to use, this module will take you through safety parameters and how to control them using BMS. By the end, you will be able to choose a suitable BMS architecture for the given electric vehicle.
Range Calculation	Now that battery pack is ready, take a look at various methods involved through which you can verify if the battery pack is compliant with your requirement.
Battery Charging	In this last module, take a look at the charging characteristics of a li-ion battery pack. By the end, you will be able to determine the complete cell characteristics for selection of a battery pack.
