Week-3 Challenge: ADVISOR Tool

AIM : To use advisor tool and simulate the following .

ADVISOR TOOL ,developed in november 1994 by the national Renewable Energy Laboratory (NREL) , allows users to simulate and analysis conventional ,advanced light , and heavy vehicles , including hybrid electric and fuel cell vehicles . The tool allows users to access the effect of changes in vehicle components ( such as motors , batteries , catalytic converters , climate control system and alternative fuels ) and other modification that might affect fuel economy , performance , or emissions .

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.

• Type advisor in command window of matlab.

• Now change EV_defaul_in from load file .
• Then change the cargo mass to 500 kg .
• Total mass will automatically change according to cargo mass .
• Now click on continue button after that a new window simulation parameter will pop up .
• Here, change the drive cycle to CYC_FTP .

• Now click on RUN button to start simulation and it will show in new window .

• Here , 17.8 km travel by the vehicle in 1 drive cycle .

• 35.5 km distance is covered by the vehicle in 2 drive cycle .

• 41.4 km covered by vehicle in 3 drive cycle .

Here Warning Message shows that it can travell upto 41.4 km only .

RESULTS :

Here we can see that the maximum distance travelled by car is 41.4 km .Hence , EV_default cannot travel distance of 45 km .

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

• For battery capacity we will change the '#of mod V nom ' describe the battery capacity .
• Now click on continue for further process .

Here first we have change value from 25-27 in # which increase voltage from 308 to 333.

• Now we have given 3 no .of drive cycle
• click on RUN button .
• It will travel distance of 44.8 kilometer .

• Now we have change value to 30 and voltage will be 370 .

• Here we have taken 3 drive cycle .
• Distance travelled by it is 49.1 km.

Conclusion :

• Here we can conclude that by increasing module of battery the voltage of batery increases and the distance travelling capacity of vehicle also increases .

3 ) Perform gradeability test with PRIUS_jpn-defaults_in file and compaire the results .

• Select PRIUS_jpn_default_in file from in load file menu.

• click on continue button .
• Now click on gradeability test and grade option .
• Select the speed and time .
• Click on Run button for simulation .

• First we have taken speed as 5mph (2.23 m/s ).
• Geadeability is 32.8 %

• Here we have increased the speed from 5mph to 10 mph (4.47 m/s)
• Gradeability is decreased to 30.3 .

• we have further increase speed to 15 mph (6.7 m/s).
• gradeability decrease to 24.4%

Speed (mph) Gradeability (%)

5 32.8

10 30.3

15 24.4

Conclusion :

• As the speed of vehicle increases the gradeability is decreasing .
