Learning ADVISOR Tool
Q1. For the 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.

Advisor:
ADVISOR, 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.
http://adv-vehicle-sim.sourceforge.net/advisor_ch1.html the link provides information about the advisor.
Aim: observe the EV_defaults in the advisor tool with 500kg cargo mass and find the can vehicle travel for 45 km with FTP drive cycle.
Processor: 1) Download the advisor tool and extract all files .
2) Add in the path Matbal and write command in the command window "Advisor"
3) Open the Advisor chose the options matrix and start.
4) In the load file option choose the EV_defaults and enter the 500kg in cargo mass. Click on continue
5) choose the drive cycle FTP and run the model get the results.
EV_defaults model with 500kg cargo mass:
Add the FTP drive cycle in drive cycle options:
After run clicked with one FTP drive cycle we get following result:
conclusion: From the above advisor results we observed that vehicle can not cover a 45km distance instead it covers 17.8 km distance.
Q2 In the above case, try changing the battery capacity and repeat the simulation.
Aim: change the battery capacity and observe the result on distance.
processer is the same as above just increase the battery capacity which is shown in the next pic:
When battery capacity increased and one drive cycle the following result in getting:
conclusion: So as per observation by only battery capacity changing the distance, not changes so we tried changing the drive cycle and following result we get
Two drive cycle:
After changing the no of drive cycle we get following result:
As per we observed that we get increased distance when we increase the no of the drive cycle, by changing the only battery cycle we can not get the increased distance.
Q3 Perform gradeability test with PRIUS_Jpn_defaults_in file
Compare your results in a table and conclude.
Ans:
AIM: Perform gradeability test with PRIUS_Jpn_defaults_in file
Processor: 1) Download the advisor tool and extract all files.
2) Add in the path Matbal and write command in the command window "Advisor"
3) Open the Advisor chose the options matrix and start.
4) In the drivetrain config options choose the PRIUS_Jpn_defaults. Click on continue
5) Select the greadaebility test option and enter the speed value check the result for different speed range.
Prius_defaults model :
Click on the continue and select the greadeability test option :
click on the grade option we popup the grade option window and change the speed in it:
After clicking on "OK' we get result with drive cycle UDDS:
As the same above we took some grads test for different speed and observed the greadeability with different speed:
*SPEED:45
greadeability test result for speed 45:
speed:50
greadeability test result for speed 50:
Speed:55
greadeability test result for speed 55:
*Speed:60
greadeability test result for speed 60:
Result:
| SPEED MPH | GREADEABILITY (%) |
| 40 | 2.5 |
| 45 | 2.2 |
| 50 | 2 |
| 55 | 1.7 |
| 60 | 1.5 |
Conclusion:
as we observed the result table best greadeability is for speed 40 mph.
as we increase the speed greadeability reduces gradually.
