Week-3 Challenge: ADVISOR Tool
Objective:
1.For EV_defaults_in File , if cargo mass is 500kg with all other defaults conditions ,can the vehicle travel for 45 km with FTP drive cycle,
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 reults in table and conclude.
Intoduction:
Advisor Vehicle simulator (ADVISOR) was first developed in November 1994 at the National Renewable energy laboratory. It was designed as an analysis tool to assist the US Department of Energy(DOE) in developing technologies for hybrid electric vehicles (HEV) through the hybrid Electric propulsion system contracts with Ford, General Motors, and DaimlerChrysler.its primary role is to highlight the system level interactions of hybrid and electric vehicle components and their impacts on the vehicle performance and fuel economy.
- the advisor was first released publicly via the internet (www.nrel.gov/transportation /analysis) in September 1998.
ADVISOR STRUCTURE :
ADVISOR was created in the matlab /simulink environment . MATLAB provides an easy-to-use matrix -based programming environment for performing calculations while simulink can be used to represent complex systems graphically using block diagrams .
ADVISOR uses three primary graphical user interface (GUI) screens to guide the user through the simulation process .With the GUIs,the user can iteratively evaluate the impacts of vehicle paramters and drive cycle requirements

1. For EV_defaults _in file, if cargo mass is 500kg with all other default condition can travel for 45 km with FTP drive cycle:
making EV_defaults in file, a nd the cargo mass changed to 500kg
single drive cycles:
1st drive cycle output:
drive cycle to 2:
2nd drive cycle output:
3 drive_cycle to CYC_FTP
3rd drive cycle output:
after the results obtained from three drive cycle that the vehicle does not travelled at 45kmph
no of drive cycle speed
1 17.8
2 35.5
3 41.4
drive cycle 4 the results should be same as 41.4.So the vehicle cannot travelled at 45 km with drive cycle CYC_FTP.
2.changing the battery capacity :
with above case the battery capacity to been changed to 30 modules and increasing voltage to 370v
Results obtained from changing battery capacity to 30 modules and increasing voltage to 370:
3.perform gradeability for prius_jpn_default :
to perform gradeability for prius _jpn_default to open prius_jpn_default in ADVIOSR vehicle simulation window,
to test the gradeability to tha particular vehicle by changing the speed in it,
IC engine:
the speed is set to be 55kmph
the results obtained :
gradeability of 55kmph is 1.7%.
for hybrid the speed is set to be 66kmph
the results obtanied:
fully electric , the speed is set to be 70:
the results obtained:
the gradeability for 70kmph is 6.3%
| vehicle type | speed in mph | speed in kmph | gradeability |
| electric | 70mph | 112.7kmph | 6.3 |
| hybrid | 66mph | 106.2kmph | 7 |
| ic engine | 55mph | 88.5kmph | 1.7 |
