Week-3 Challenge: ADVISOR Tool

Week 3

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.

Ans:

• Electric Vehicle:

An electric vehicle (EV), also called electrics is a vehicle that uses one or more electric motors or traction motors for propulsion. An electric vehicle may be powered through a collector system by electricity from off-vehicle sources or may be self-contained with a battery, solar panels, fuel cells. or an electric generator to convert fuel to electricity.

• FTP Drive Cycle:

The FTP-75 (Federal Test Procedure) has been used for emission certification and fuel economy testing of light-duty vehicles in the United States. The test is often referred to as simply FTP (this should not be confused with the FTP test for heavy-duty engines).

The FTP-75 and the FTP-72 are two variants of the EPA Urban Dynamometer Driving Schedule (UDDS).

The FTP-75 cycle is derived from the FTP-72 by adding a third phase of 505 s, identical to the first phase of FTP-72 but with a hot start.

The third phase starts after the engine is stopped for 10 minutes

Thus, the entire FTP-75 cycle consists of the following segments:

1. Cold start transient phase (ambient temperature 20-30°C), 0-505 s.
2. Stabilized phase, 506-1372s.
3. Hot soak (min 540 5. max 660 s).
4. Hot start transient phase. O-505's

Given data:

Vehicle type= EV_defaults_in

Cargo mass=500 kg

Drive cycle=FTP drive cycle

• Solution:

Following steps:

Step 1: Open the advisor tool and click start to open the vehicle input in the advisor simulator.

Step 2: Search for the 'EV_Defaults_in' file from the load file and click the file to open.

Step 3:

Step 4: In the advisor tool, the simulation consists of every parameter of vehicle modelling, like mass, vehicle type, energy storage, motor, transmission, wheel/axle, etc.

Step 5: Now change some parameters which present in "EV_defaults_in" the file, like cargo mass to 500 kg.

Step 6:

Step 7: Then click continue to open the simulation parameters, the simulation parameter consists of different drive cycles and to create an individual own drive cycle by giving different data to the Simulink parameter. Acceleration test. Gradeability test, parametric study, etc.

Step 8:

Step 9: Now, search for the ‘CYC FTD' file from the drive cycle list in the advisor tool.

Step 10:

Step 11: Then click the file which is CYC FTP drive cycle.

Step 12:

Step 13: Presently tick the run to see the result.

Step 14:

Step 15:

For Default Condition:

For several Drive Cycle is equal to 1 and vehicle travelled the Distance is 17.8 km

For several Drive Cycle is equal to 2 and vehicle travelled the Distance is 35.5 km

For several Drive Cycle is equal to 3 and vehicle travelled the Distance is 48.2 km

For several Drive Cycle is equal to 4 and vehicle travelled the Distance is 48.2 km

For several Drive Cycle is equal to 10 and vehicle travelled the Distance is 48.2 km

Step 16: If Cargo Mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with an FTP drive cycle?

For several Drive Cycle is equal to 1 and vehicle travelled the Distance is 17.8 km

For several Drive Cycle is equal to 2 and vehicle travelled the Distance is 35.5 km

For several Drive Cycle is equal to 3 and vehicle travelled the Distance is 41.4 km

For several Drive Cycle is equal to 4 and vehicle travelled the Distance is 41.4 km

For several Drive cycle is equal to 10 and vehicle travelled the Distance is 41.4 km

• OBSERVATION:

1. The vehicle cannot travel for 45 km with an FTP drive cycle. Because in increases of cargo mass to 500 kg, the vehicle can only travel up to 41.4 km.
2. If the initial default condition is now with cargo mass at 136 kg. The vehicle can go up to 48.2 km.

So a boost in load begins to a decline of load to travel the higher distance.

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

Ans:

Following steps:

Step 1: Open the advisor tool and click start to open the vehicle input in the advisor simulator.

Step 2: Search for the 'EV_Defaults_in' file from the load file and click the file to open.

Step 3:

Step 4: In the advisor tool, the simulation consists of every parameter of vehicle modelling, like mass, vehicle type, energy storage, motor, transmission, wheel/axle, etc.

Step 5: Now change some parameters which present in "EV_defaults_in" the file, like cargo mass to 500 kg.

Step 6:

Step 7: IF THE BATTERY CAPACITY IS BELOW 25 MODULES: WHICH IS 15 MODULES.

For several Drive Cycle is equal to 1 and vehicle travelled the Distance is 17.7 km

For several Drive Cycle is equal to 2 and vehicle travelled the Distance is 24.8 km

For several Drive Cycle is equal to 3 and vehicle travelled the Distance is 24.8 km

For several Drive Cycle is equal to 4 and vehicle travelled the Distance is 24.8 km

For several Drive Cycle is equal to 10 and vehicle travelled the Distance is 24.8 km

Step 8: IF THE BATTERY CAPACITY IS ABOVE 25 MODULES: WHICH IS 35 MODULES.

For several Drive Cycle is equal to 1 and vehicle travelled the Distance is 17.8 km

For several Drive Cycle is equal to 2 and vehicle travelled the Distance is 35.5 km

For several Drive Cycle is equal to 3 and vehicle travelled the Distance is 56.5 km

For several Drive Cycle is equal to 4 and vehicle travelled the Distance is 56.6 km

For several Drive Cycle is equal to 10 and vehicle travelled the Distance is 56.5 km

• OBSERVATION:

1. Whenever the battery capacity is less than 25 modules, the vehicle goes less distance travelled.
2. Whenever the battery capacity is more than 25 modules, the vehicle takes more distance travelled
3. Because the battery capacity is power or Energy storage that the vehicle is dependent on to Travel a certain distance.
4. If energy is more the distance travelled by vehicle is more, and if the energy is less the distance travelled by vehicle is less.

3. Perform gradeability test with PRIUS_Jpn_defaults_in file

Compare your results in table and conclude.

Ans:

• Toyota Prius:

The Toyota Prius is a parallel hybrid; this means it has a gasoline engine and electric motor that are separate from one another. Further, each can run on its own. Toyota designed the Prius so that it would utilize electric power (which it stores in the battery) instead of gasoline power whenever possible.

• Solution:

Following steps:

Step 1: Open the advisor tool and click start to open the vehicle input in the advisor simulator.

Step 2: Search for the 'PRIUS_Jpn_defaults_in' file from the load file and click the file to open.

Step 3:

Step 4: In the advisor tool, the simulation consists of every parameter of vehicle modelling, like mass, vehicle type, energy storage, motor, transmission, wheel/axle, etc.

Step 5: Then click continue to open the simulation parameters, the simulation parameter consists of different drive cycles and to create an individual own drive cycle by giving different data to the Simulink parameter. Acceleration test. Gradeability test, parametric study, etc.

Step 6:

Step 7: Now, search ANY for the ‘CYC FTD' file from the drive cycle list in the advisor tool.

Step 8:

Step 9: NOW PERFORM THE GRADABILITY TEST:

1. OPEN THE GRADE OPTIONS MENU FOLDER

Case 1: SPEED=55mph=88.55Kmph and TIME=20 seconds. Other all parameter set as default.

Case 2: SPEED=65mph=88.55Kmph and TIME=20 seconds. Other all parameter set as default.

Case 3: SPEED=75mph=120.7Kmph and TIME=20 seconds. Other all parameter set as default.

Case 4: SPEED=85mph=136.8Kmph and TIME=20 seconds. Other all parameter set as default.

Case 5: SPEED=95mph=152.9Kmph and TIME=20 seconds. Other all parameter set as default.

SO BY KEEPING THE ALL SYSTEM ENABLE, SPEED VS GRADEABILITY (%) IS TAKEN FROM THE ADVISOR TOOL IN TABLE RESULT:

• OBSERVATION:

1. If speed is less, the gradeability percentage is more.
2. If speed is more, the gradeability percentage is less.
3. So speed and gradeability percentage are inversely proportional to each other.
