Project 2

Design and Develop a simulink model to understand Energy analysis of EVs on different driving cycles:

Below mentioned block are required to find out analysis:

1. Driving Cycle

2. Electric Vehicle

3. Energy analaysis subsystem

Simulink_Model:

Driving_Cycle:

Driving cycle is required for Varient in speed with reference to time. here used in FTP driving cycle.

Electric Vehicle:

In Electric vehicle what are subsystem required to develope electric vehicle mentioned below here.

1. Longitudinal Driver

2. Controller

3. Vehicle Dynamics

4. Battery_Soc

1.Longitudinal Driver:

In this block provide acceleration and braking for driver inputs according to speed of vehicle. Here brake command is not provide.

2. Controller:

In controller getting input from diver block and create pwm signal depends upon the vehicle input and contolled the motor with H-Bridge. In general Electric vehicel motor power rating is 50-60 KWh

3. Vehicle Dynamics:

In Vehice dynamics block getting inpt from dc motr and drive the tire based on the dc motor speed. There is no aerodyamic reistsnace and Hill climbing forces also.

4. Battery_Soc:

In Battery soc system helps to find our the soc level of battery after completing driving cycle. Used in coloumb couting method.

Results:

Simulink Model:

Energy analysis:

In enery analysis input of driving cycle and calculating forces of Aerodynamic, Hill climbing, Rooling resistance and gradiant forces.

Total propulsion Power= F*V

Here i have attached the simulink model and results:
