Week-3 Challenge: ADVISOR Tool
ADVISOR TOOL
Aim:
- For EV_defaults_in file, simulate for the range of the Vehicle carrying the Payload of 500kg.
- Changing the Battery Capacity of the above Vehicle for the next Simulation.
- To Perform the Gradeabilty taest for PRIUS_jpn_defaults_in Vehicle.
ADVISOR: a systems analysis tool for advanced vehicle modeling
Advanced 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 Vehicle 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.
STUDY: 1
- To check if the vehicle can travel can travel for 45 Km with cargo mass of 500 kg with all other default conditions, with FTP drive cycle.
Open the ADVISOR Tool and load the file EV_defaults_in.
MAIN MODEL:
DRIVE CYCLE: FTP-1
RESULT:
- FTP Drive cycle constitutes a total Distance of 17.8 km in a single cycle. in order to check for the Range for 45km, to increase the Drive Cycles.
DRIVE CYCLE: FTP-2
RESULT:
- FTP Drive cycle constitutes a total Distance of 35.5 km in a double cycle.
DRIVE CYCLE: FTP-3
RESULT:
The distance traveled bythe vehicle in 3 drive cycles is 41.4 km. Used completely 1000% SOC
| No.of Drive Cycle | Distance covered in kms |
| 1 | 17.8 |
| 2 | 35.5 |
| 3 | 41.4 |
The minimum distance travel by car is 17.8 km with drive cycle CYC_FTP-1 whereas the maximum distance travel by car is 41.4 which consumes 100% of battery in 3 Drive Cycles.
Therefore EV_default cannot travel distance of 45 km due to insufficient SOC.
STUDY-2:
In the above case , try changing the battery capacity and repeat the simulation.
- In-vehicle input window we will change the capacity of battery form energy storage.
MAIN MODEL:
Energy Storage System with 27 Modules:
RESULTS:
Energy Storage System with 30 Modules:
RESULTS:
Energy Storage System with 40 Modules:
RESULTS:
- While changing the battery modeules to increasing the distance of the vehicle.
- Changing the battery modules 30 in the Drive Cycle 3 we get changes in distance travel 49 .1 km.
STUDY-3:
- To perform the Gradeablity test for PRIUS_jpn_defaults_in Vehicle
MAIN MODEL:
Speed 40 miles/hr or 64.37 km/hr
Gradeability = 11.7%
Speed 45 miles/hr or 72.4 km/hr:
Gradeability = 10.7 %
Speed 50 miles/hr or 80.5 km/hr:
Gradeability = 9.7 %
Speed 55 miles/hr or 88.5 km/hr:
Gradeability = 8.9 %
Speed 60 miles/hr or 96.5 km/hr:
Gradeability = 8.1 %
For Duration - 10 sec
| S.No | Vehicle Speed mph | Vehicle Speed kmph | Gradeability % |
| 1 | 40 | 64.37 | 11.7 |
| 2 | 45 | 72.4 | 10.7 |
| 3 | 50 | 80.5 | 9.7 |
| 4 | 55 | 88.5 | 8.9 |
| 5 | 60 | 96.5 | 8.1 |
When Vehicle speed increase there is a decrease in gradeability.
