Week-3 Challenge: ADVISOR Tool

Aim:

To study about the vehicle simulation using ADVISOR tool by providing extra load, changing the battery capacity and performing the gradeability test on a particular vehicle.

Objective:

-For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 4kmwithFTP drive cycle? Conclude your observations.

-In the above case, try changing the battery capacity and repeat the simulation.

-Perform gradeability test with PRIUS_Jpn_defaults_in file. Compare your results in table and conclude.

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.

Uses of ADVISOR tool:

• 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.

CASE 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.

cargo mass to 500 kg is set

we will change the drive cycle from default condition to FTP drive cycle

NO. OF CYCLES = 3

Result shows that for 3 number of cycles at the given conditions,the vehicle can travel for only 41.4km

CASE 2:

Now, we are changing the battery capacity and repeat the simulation.

we have changed the battery capacity from 25 to 50V.

If we increase the power capacity of the battery to 50 kW, we can see that the vehicle can travel up-to a distance of 53.5 km.

CASE 3:

Now, performing gradeability test with PRIUS_Jpn_defaults_in file

perform the gradeability test on the PRIUS_Jpn_defaults_in file

Gradeability at 20mph is 19.8%

similarly faor all same parameters

Input Speed (mph)	Gradeability (%)
20	19.8
30	14.7
40	11.7

Now fully electric at speed 20 mph

Hybrid at 20mph:

Result showing NA

Conclusion:

-We have checked that for the EV_defaults_in file, if the cargo mass is 500 kg with all other default condition and using the FTP drive cycle the vehicle travel for a distance of 45 kms.

-We can observe that for as the power capacity of the battery increases the distance which can travelled by the vehicle also increases.

-We have performed gradeability test with PRIUS_Jpn_defaults_in file and computed the results in a table.
