Final Project: Electric Rickshaw modelling

Specification in Excel sheet

We use 3 drive cycles

FTP,WOT(user defined) and UDDS drive cycle.

FTP75 drive cycle plot

it runs for 2474 sec

WOT drive cycle

we will run this for 8000sec

Plot

UDDS drive cycle

Longitudinal Driver

MOTOR DRIVE

our motor controller is PWM H-bridge

we use the thermal port to dc motor to a temperature sensor

VEHICLE BODY DYNAMICS

DC motor is connected to a simple gear block which in turn is used to power the wheels of the vehicle.

Simple Gear

we use tyre magic formula to simulate the tyres of the vehicles.

rolling resistance is enabled.

VEHICLE BODY

frontal area and drag coefficient are enabled.

BATTERY SYSTEM

a current sensor is connected to the H Bridge controller and the signals are connected to a controlled current source.

RESULTS

for FTP drive cycle we keep runtime as 2474

actual velocity is almost matching

Motor temperature is shown below

controller temperature

SOC

100 km constant speed driving at 45 kmph.

runtime is kept as 8010 sec

actual drive cycle is lower.

SOC

CONCLUSION

a detailed MATLAB model of an electric rickshaw three wheel passenger vehicle has been done with relevant plots,parameters and measurements.
