Simulation using ADVISOR Tool
Aim : Use ADVISOR tool and simulate t
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.
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 results in table and conclude
SOLUTION
Drivetrain selection-
From the drivetrain popup menu you will be able to select the drivetrain configuration of the vehicle (Series, Parallel, etc.) which will cause the schematic of the vehicle configuration in the left portion of the figure to change accordingly. This will also modify which components are available for the type of drivetrain chosen.
Selecting components-
After selecting the drivetrain configuration, all the components of the vehicle can be selected using the popup menus, or by clicking on the component in the picture. To the left of the component popup menus is a pushbutton that will allow you to add or delete components by selecting their corresponding listed m-files. The m-file of a specific component can be accessed for viewing or modifying from either the component pushbutton or by clicking on the component of the picture.
1. For EV_defaults_in file, if cargo mass is 500 kg with all other default conditions, the vehicle can not travel for 45 km with FTP drive cycle>>
In ADVISOR tool there are various simulink models of car are present as output called simulation of vehicle that based on IC engine, Electric vehicle, and Hybrid vehicle. By using this tool many results are obtained.A changes of value of the motor, generator, battery capacity and some other vehicle parameters are made by the advisor tool outputs are obtained by run option. That dialog box are shown below-
Simulated observation is attached below--
CYCLE 1-
Considering mass value as 500 kg and cycle time 1.
CYCLE 2-
Considering mass value as 500 kg and cycle time 2.
CYCLE 3-
Considering mass value as 500 kg and cycle time 3.
CYCLE 4-
Considering mass value as 500 kg and cycle time 3.
EMMISSION-
As this is a pure EV and run with power supply from high voltage battery, it does not emmit any gas in atmosphere. A complete cemical energy has converted into electrical energy.
OBSERBATION-
By the observation 4 cycles of this model, the vehicle could'nt travel for 45 km with FTP drive cycle. The maximum distance travel in default model is 41.4 km. This maximum distance travel of vehicle is obtained only by increasing the number of cycle.
Cycle 3 is the maximum number of cycle which the battery capacity is capable of acceleration. The battery is drained in number of cycle time 3
So the vehicle travel for 45 km with FTP drive cycle is not possible by the default condition.
2.In various case of changing battery capacity and repeating simulation, we get>>
i)For battery module 5--
ii)For battery module 12--
iii)For battery module 25--
iv)For battery module 35--
v)For battery module 40--
vi)For battery module 45--
vii)For battery module 50--
OBSERBATION-
As the battery capacity is increasing changing the battery module number and we can see the distance covered for 1 cycle of time is changing. The distance become constant from battery module 25, that is 17.8km.
3.Performing gradeability test with PRIUS_Jpn_defaults_in file with all default condition, we get>>
The default model parameters are shown in below model-
>Changing various speed for the gradeability test we get--
GRADEABILITY SPEED-
We have to give the speed reference of this gradeability test in mile/hr .
Conversion of mph to kmph-
1 Mile = 1.60934 Km
Speed(km/h) Gradeability(%)
136.78 0
135.16 1.0
