Final Project: Design of an Electric Vehicle

Create a MATLAB model of electric car which uses a battery and a DC motor. Choose suitable blocks from Powertrain block set. Prepare a report about your model including following:

Objectives:

1. System level configurations

2. Model parameters

3. Results

4. Conclusion

SOLUCTION:

ABSTRACTS:

INTERDUCTION:

1. System level configurations

MATLAB/SIMULINK MODEL:

VEHICLE SUB SYSTEM:

SOC CALUCLATION SUB SYSTEM:

2.Model parameters

vehicle body:

GAIN OF SOC:

SOLVER CONFIGRATION:

RESULTS:

SOC ESTMATION SCOPE:

THE SIMULINK HAS DONE FOR 2474 SEC>AT THE BEGINING THE SOC.WAS100%AND AFTER 2472 SECOF SIMULINK THE SOC DECRECED TO 19%. REGENERATIVE BRAKING WAS TAKING PLACE

CURRENT SCOPE:

BASED ON THE DRIVE CYCLE DATA AND OTHER PARAMETERS THE DC MOTOR DRWN CURRENT FOR ACCELERATION AND ROTATION TO MAINTAIN THE SPEED OF THE VEHICLE.

SPEED SCOPE:

HERE WE CAN SEE TWO DIFFERENT COLOUR LINE IS OVERLAPING EACH OTHER IN THIS PLOT. THE BLUE LINE IS THE REFERENCE SPEED AS PER THE DRIVE CYCLE.THE YELLOW LINE IS ACTUAL SPEED OF THE VEHICLE THAT HA TAKEN FOR FEEDBACK.THE MAXIMUM ACTUAL SPEED IS 25 M/SEC.

4.CONCLUSION:

THIS PARAMETERS CAN BE CHANGED. WE CAN CHANGE THE MOTOR TYPE. MOTOR RATING CONTROLLER RATING BATTERY TYPE AND RATING.DRIVE CYCLE ETC. BASED ON THOSE PRAMETERS THE SIMULINK RESULT OF SOC ESTIMATION,CURRENT SPEED WILL ACCORDINGLY.WE CAN USE DIFFERENT FROM EXTRA SOURCE DIRECTORY AND ADD OTHER FUNCTION:LIKER TEMPERATURE SENSOR.AS THIS IS A PURE EV,WE CAN MAKE HYBRID EV AND ADD OTHER FUNCTION FOR SIMULTANEOUSLY CHAGING OPERATIONS OF IC ENGINE AND MOTOR.
