Week-3 Challenge: ADVISOR Tool
Objective:
Use ADVISOR tool and simulate the following
1. For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations.
2. In the above case, try changing the battery capacity and repeat the simulation.
3. Perform gradeability test with PRIUS_Jpn_defaults_in file
Compare your results in table and conclude.
ADVISOR tool:
DVISOR, NREL’s ADvanced VehIcle SimulatOR, is a set of model, data, and script text files for use with Matlab and Simulink. It is designed for rapid analysis of the performance and fuel economy of conventional, electric, and hybrid vehicles. ADVISOR also provides a backbone for the detailed simulation and analysis of user defined drivetrain components, a starting point of verified vehicle data and algorithms from which to take full advantage of the modeling flexibility of Simulink and analytic power of MATLAB.
You may benefit from using ADVISOR if you want to:
- estimate the fuel economy of vehicles that have not yet been built
- learn about how conventional, hybrid, or electric vehicles use (and lose) energy throughout their drivetrains
- compare relative tailpipe emissions produced on a number of cycles
- evaluate an energy management strategy for your hybrid vehicle’s fuel converter
- optimize the gear ratios in your transmission to minimize fuel use or maximize performance, etc.
1. For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with FTP drive cycle? Conclude your observations.
Ans:
The model EV_defaults_in has the following:
1.Max power of 25KW
2.Battery peak voltage of 308V
3.Weight of 1144 kgs
4.Cargo mass added 500Kgs
5.Battery tpe Leadacid
Values changed to
Drive cycle Cyc_FTP is assigned as it has only 17km per cycle i have given 3 cycles
Maximum achieved distance was only 41.4kms and battery drainied to 1%
2. In the above case, try changing the battery capacity and repeat the simulation.
Ans:
Then another battery called nickel-metal hydride battery is used it has 436v and total power of 75KW
This battery arrangement has achieved more than required target and reached a number of 53.3kms
3. Perform gradeability test with PRIUS_Jpn_defaults_in file
Compare your results in table and conclude.
Ans:
Gradeability test with default parameters:
speed: 55
duration: 10secs
Gear no: 1
All systems Enabled
Gradabilty was found to be 8.6% at 88.5kmph
Gradability test with increased speeds:
speed: 60
duration: 10secs
Gear no: 1
All systems: Enabled
gradability at 96.6kmph is 8.1%
Gradability test with increased speeds:
speed: 60
duration: 10secs
Gear no: 1
Energy Storage disabled
Gradability test :
speed: 60
duration: 10secs
Gear no: 1
Fuel converter disabled
