Final Project: Electric Rickshaw modelling
Final project E-rickshaw modelling
Objectives:
- Rear wheels driven by PM brushed type motor
- Assume efficiency points of motor controller and motor
- Make an excel sheet of all input and assumed data
- Results: For any three standard driving cycles show energy consumption, temperature rise of motor and controller.
Block Diagram:
In the designed Electric Rickshaw main blocks are Battery, drive cycle, controller, DC Motor, Vehicle body & Transmission system. Drive cycle is the input data like how a human drive his actual vehicle here FTP75, WOT & Excel (Manually Prepared in Excel sheet) drive cycles are used to make the designed vehicle to give the output how it reacts to the drive cycle. The main objective is to obtain the speed by the driver, to estimate the temperature of Motor and Controller, to estimate the sates of charge (SOC), distance travelled by the vehicle. There is a SOC block that will estimate the state of charge of a battery, distance is calculated by speed and time parameters for all the three Drive cycles.

Drive Cycle:
Drive cycle is assumed as the driver's input of a vehicle, it replaced how a driver will drive a vehicle. Here I have used four drive cycles which is used to test the vehicle performances. These drive cycle will have high speed, low speed, braking conditions in it. There are different drive cycles like signal builder block, FTP75 ,constant speed 45 KMPHetc., Here in this model I have used FTP 75, WOT & Manually prepared in excel Drive Cycle source.
RESULT ANALYSIS.
1.I HAVE ANALYZED THE DATA FOR TEMPERATURE AND DISTANCE.
2. TEMPERATURE GRAPH IS ALSO ATTACHED.
3. HERE WE CAN SAY THAT DRIVE CYCLE IS TRACKING THE DATA AS IT FOR FTP DRIVE CYCLE.
4. FOR 13250 SEC. E RICKSHAW COMPLETED 100 KM AT 45 KMPH .
5. SO WE CAN SAY THAT IT COVERED THE DISTANCE 100 KM FOR 45 KMPH.
