Hybrid Electric Vehicle (HEV) power train based on Electric vehicle Systems. The HEV power train is of the series-parallel type. This HEV has two kinds of motive power sources: an electric motor and an Internal Combustion Engine (ICE), in order to increase the drive train efficiency and reduce air pollution. It combines the advantages of the electric motor drive (High available power at low speed) and the advantages of an Internal Combustion Engine (High dynamic performance and low pollution at high speeds). In this project and implimentation, the fundamental architecture of the feed-forward parallel hybrid-electric vehicle system is described, together with dynamic equations and basic features of sub-system modules. Which mainly explores engine efficiency in an intuitive manner, and driving cycle demonstrate the potential of the selected hybrid system to significantly improve vehicle fuel economy, information about series parallel hybrid electrical vehicle’s technology and defines tools for modeling the vehicle. The components of the vehicle; including internal combustion engine, driving machine, generator machine, batteries and transmission, and also vehicle’s load model and control logic is modeled run.


A series-parallel hybrid electrical vehicle utilizes an internal combustion engine (ICE), electrical machines (EM) for driving the vehicle and generating electricity, power electronic components (PE), advanced electronic control units (ECU), a complex transmission and high voltage battery packs. As the combination of these different components, hybrid electrical vehicle engineering is the integration of automotive engineering, electrical and electronic engineering, computer hardware and software engineering and also chemical engineering. Increase in the number of components also makes the integration and optimization of the working of these components more important and challenging. While hybridizing a vehicle, performance demands, fuel economy/emission reduction criteria and proper and safe use procedures should be defined clearly. While defining the optimal working of these components, the driving cycle of the vehicle should also be considered, too. The level of hybridization should be defined here. As all new components in a hybrid vehicle bring more weight, complexity and cost to the system, defining of the level of hybridization and investigating the amortization of the investment is an important part in the hybridization of a vehicle. A flexible computer modeling and simulation tool is important in optimization of the hybrid vehicle.

The Problem

Transportation consumes 20% of our energy and 20% of CO2 emissions every year.
Not sustainable for the next 50 years
“I feel more confident than ever that the power to save the planet rests with the individual consumer.”- Denis Hayes.
Consumers can have a positive impact on the environment.

Hybrid Vehicle

Hybrid vehicles utilize two or more sources of energy for propulsion.
In the case of HEVs, one of the sources is an electric motor.
Eg. Honda Clarity

The Solution

HEVs and Fuel cell technology are currently the leading solutions compatible to sustainable development
Both have advantages and disadvantages
Barriers to fuel cell economy
Advantages to HEVs over current Internal Combustion engines
The current disadvantages to fuel cells

Parallel Hybrid

IC engine, transmission, electric motor, and batteries.
Designed to run directly from IC engine or the electric motor.
Both the combustion engine and the electric motor are used at the same time during quick acceleration, on steep ascend, or when either the engine or the motor needs additional boost.
This is suited for highway driving

Series Hybrid

The series hybrid car also has a an IC engine, transmission, electric motor, and the batteries with the addition of the generator.
The engine is not connected to the transmission rather it is connected to the electric motor.
This means that the transmission can be driven only by the electric motor which draws its energy from the battery pack, the engine or the generator.
A hybrid car with a series drive train is more suited for city driving conditions since the engine will not be subjected to the varying speed demands (stop, go and idle) that contributes to fuel consumption.
