Final Project: Electric Rickshaw modelling
Drive cycle:It is used to give referrence drive cycle that is the input.
Tire:
The tire(magic formula) block is used for tire.
Gear:
Simple gear is used to transfer the output torque from motor to the tire.
DC motor
The output torque is produced with the help of DC motor
Vehicle body:
The vehicle body is used is used to represent the body of vehicle.
H-bridge
The h-bridge is used to control the speed as well as direction of dc motor according to the input signals given by the pwm signals.
Controlled PWM voltage.
This is used to give the control signals to the input of H-bridge
Generic battery:
It is used to provide the power for the dc series motor.
Longitudinal driver:
It acts as a driver to give the necessary acceleration and brake commands.
Energy block:
It is a subsystem having the blocks to calculate the energy required
The total force is multiplied with velocity which is then integrated to get the power.
Circuit:
FTP output
User defined
Result
The simulation is ran for various cycles,the corresponding temperatures,energy and distances are calculated.
For higher speed and distance temperature generated is also high
