A brief Seminar Presentation on the Hybrid Electric Vehicle HEV Powertrain

Introduction

Overview

This document outlines the syllabus for a course on electric and hybrid vehicles. It covers the history of electric vehicles, the different types of electric vehicles, and the reasons for the recent surge in interest in electric vehicles.

Key Technology Trends in EVs

The following are the key technology trends in EVs that were covered in the lecture:

• The use of lithium-ion batteries in place of lead-acid batteries
• The development of more efficient electric motors
• The use of regenerative braking to capture energy and store it in the battery
• The development of smart charging systems that can optimize the charging process

Disappearance and Resurgence of EVs

Electric vehicles were first introduced in the late 19th century, but they gradually disappeared from the market in the early 20th century. The invention of the starter motor in 1911 made it possible to start gasoline-powered vehicles without the need for a separate electric motor, and this led to the decline of electric vehicles.

In recent years, there has been a resurgence of interest in electric vehicles. This is due to a number of factors, including:

• The rising cost of gasoline
• The growing awareness of the environmental impact of gasoline-powered vehicles
• The development of new technologies that have made electric vehicles more affordable, more efficient, and more convenient to use
