Week-3 Challenge: ADVISOR Tool
Download and Setting up ADVISOR
Step-1: Download Advisor from https://sourceforge.net/projects/adv-vehicle-sim/
Step-2: Unzip the folder and add it to MATLAB location
Step-3: Once added to the Matlab location it will be shown in the Current Folder, then right click on the advisor folder and 'Add folder and subfolders'
Step-4: Then type as 'ADVISOR' in the command window this opens up the ADVISOR 2003-00-r0116 April 24,2013 window. Chosse Metric over US (to have readings in Km) and then click 'START' Button
Question-1
Step-1: At load file location change Parallel_default_In to EV_defaults_in
Step-2: Cargo mass is changed to 500Kg which also automatically updates the calculated mass, Then click 'Continue'
Step-3: Simulation parameter window will pop up, the drive cycle is set to 'CYC_FTP'
challenge is to find if the vehcile can travel to 45km with FTP drive cycle
Step-4: After the choice of CYC_FTP, By default 1 Drive cycle shall be considered. Then Press 'RUN' buttom which open the results window and shows distance covered as 17.8Kms and State of charge of battery has reduced from 1 to 0.6. Which means 40% of the charge (stored energy) is consumed
Step-5: Similarly increasing the number of drive cycles, following is observed
2 Drive cycles --> 35.5kms distnace covered and --> 80% of the of the charge is consumed
3 Drive cycles --> 41.4kms distance covered and --> 100% of the of the charge is consumed
Inference : Hence with the above observations, The EV cannot travel for 45kms with FTP drive cycle as the stored energy completely deplets at 41.4kms
Question-2
Requirement : In case of Question-1 battery capacity to be changed and simulations to be repeated
Step-1: In vehicle input window ensure that EV_defaults_in is chosen as a load file
Step-2: In the same vehicle input window chose the number of battery modules , accordingly the battery voltage and the weight of the battery will get updted automatically
Step-3: Continue and in next window chose the number of drive cycles
Step-4: In this case following is the analysis criteria followed to chose the right number of battery modules, required voltage and the number of drive cycles required for an EV to cover 45km distance.
26 modules with 2 Drive cycles
27modules with 2 Drive cycles
28modules with 2 Drive cycles
26modules with 3 Drive cycles
27modules with 3 Drive cycles
28modules with 3 Drive cycles
Tabulated results of simulations and Conclusion is given below
From the above table, 28 battery modules (with total of 345V) with 3 Drive cycles is required to cross over 45kms (in this case 46.3kms)
Question-3:
Step-1: Move to the vehicle input window and chose the 'Prius_Jpn_defaults_in' press 'Continue' to move to 'Simulation Parameters' window
Step-2: Check the Gradeability Test and Press Grade Options
Step-3:
In this particular case different speed (40mph, 45mph, 50mph & 55mph) are checked for both 10sec and 20sec. All systems enabled should be checked
Step4 : Simulation results are given below
Speed 40mph , duration = 10sec
Speed 45mph , duration = 10sec
Speed 50mph , duration = 10sec
Speed 55mph , duration = 10sec
Speed 40mph , duration = 20sec
Speed 45mph , duration = 20sec
Speed 50mph , duration = 20sec
Speed 55mph , duration = 20sec
Inference: Data Tabulated from the above simulations are as in the table. Decrease in Greadability is seen with the increase in vehicle speed both for 10Sec and 20Sec durations.
