EV Architecture

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 to the industrial approach of the powertrain selection process. Where you gain a better understanding of both “mechanical” and “electric” aspects of powertrain design architecture, key components behaviour and functions and the various forces acting on the vehicle and their impact on powertrain selection for EV applications. By the end of the program, you will be able to perform initial calculations to select a suitable motor and power unit for the required Electric Vehicles.

This course has been designed for you to build the industrial knowledge development experience with most basic concepts for development and calculation of an Electric Vehicle while performing the calculations for one at the same time. This program will benefit building your fundamental base and will give a fine guideline that how to select the suitable powertrain for EV applications.

Course Syllabus

Module	Description
EV Introduction	We will start by taking a look at the basics of the automobile – the basic requirement for a vehicle to be labelled as an automobile. The various architecture present and their combinations. Following this, we will travel through time and look at various developments in the transportation industry in terms of automobiles, and in the process understand the factors that have led to the coming of EV in today’s time. At last, we will discuss various factors affecting EV market trends for the last decade and current and upcoming scenarios. *Case Study: Hybrid Architecture of BMW i8 and SHVS technology by Suzuki.*
Vehicle Longitudinal Dynamics	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 behaviour under various load conditions. What is the right wheel to choose for your vehicle? How can you minimise 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.
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.
