Final Project: Electric Rickshaw modelling

OBJECTIVE:

To design the simulink model , to operate the EV in three different modes and corresponding graph should be plotted.

Model Parameters:

Four types of drives cycle was carried out with this model,

i) Drive cycle source

ii) Signal Builder

iii) Slider gain for Manual Operation

iv) Wide Open throttle

• multiport switch has been icluded in order to selcet the various drive cycle inputs.

• Longitudunal driver block is utilised to provide accerleration and deacceleration with the help of refernce value and feedback.

• Motor drive is the block which consist of Permanent magnet DC motor with thermal measurement unit and electrical drive unit.

Motor and Mechanical Drive:

this subsystem consist of DC motor with mechanical coupling arrangemets.

Vehceile dynamics block consist of Wheel arrangement system with vechile body

conversion block

Conclusion :

The model has been created in order to match the requirement. The above model runs for 15kmph speed throughout the process and it can controllable, enen though the refernce input value increases the model coulnt cross 15kmph speed. concentration should be given in order to run the vehicle at the desired spped of 45kmph.

All other parameters are in line with the requirement and the graph were plotted.
