Week-3 Challenge: ADVISOR Tool

TThirupathish Vangoor15 Jan 2022

Objective:

to use advisor tool and simulate following

THE MODEL OF ADVISOR are:

*mostly empirical .relying on drivetrain component input /output relationship measured in the laboartory .and

* quasi-static , using data collected in steady state

example-constant torque and and speed.tests and correcting them for transient effect such as the rotational intertia of drivetrian components.

1. for EV-default in file ,if the cargo mass is 500 kg with all other default condition ,can cthe vehicle travel for 45 km with FTP drive cycle ?

considering the case for an typical EV iets simulate EV -default in an electrical vehicle with following specification.

Enery storage :lead acid battery with 25 modules having 308 V as nominal with 0.92 motor efficiency

motor: AC induction motor with 75wk

transmission:manual

drive:front wheel drive

cargo mass: 500kg

here inoder to drive the battery completed to soc 0%for calculating the triange of vehicle 4 drive cycle are repeated so that vehicle will travel 70.8 km total find out at what soc is 0

in the above fig . first plot show the drive cycle for which has travelled . the second plot shows that soc dail with time the third and fourth graph show the power output according to the throttle condition .

after running the simuation we can see that soc becomes zero after aproximately 2.5 drive cycle as show at the right hand side the distance travelled gy vehicle is 41.4 km the vehicle cannot travel 45km in a signal charge.

2.in the above case. try changing the battery capacity and repeat the simulation:

in this case same default condition are taken that are intiate in question 1and battery capacity will changed for accelerating vehicle that will increase the vehicle distancs travel 1km

inorder to achieve a range of 45km 3more modules of battery have been making the total modules 28 and nomunal voltage to 345v.
