ADVISOR Tool For Simulating:-

ADVISOR, NREL’s ADvanced VehIcle SimulatOR, is a set of model, data, and script text files for use with Matlab and Simulink. It is designed for rapid analysis of the performance and fuel economy of conventional, electric, and hybrid vehicles. ADVISOR also provides a backbone for the detailed simulation and analysis of user-defined drivetrain components, a starting point of verified vehicle data and algorithms from which to take full advantage of the modelling flexibility of Simulink and analytic power of MATLAB.

We may benefit from using ADVISOR if we want to:

• estimate the fuel economy of vehicles that have not yet been built
• learn about how conventional, hybrid or electric vehicles use (and lose) energy throughout their drivetrains
• compare relative tailpipe emissions produced on several cycles
• evaluate an energy management strategy for our hybrid vehicle’s fuel converter
• optimize the gear ratios in our transmission to minimize fuel use or maximize performance, etc.

The models in ADVISOR are:

• mostly empirical, relying on drivetrain component input/output relationships measured in the laboratory, and
• quasi-static, using data collected in steady-state (for example, constant torque and speed) tests and correcting them for transient effects such as the rotational inertia of drivetrain components.

ADVISOR was preliminarily written and used in November 1994. Since then, it has been modified as necessary to help manage the US DOE Hybrid Vehicle Propulsion System subcontracts. Only in January 1998 was a concerted development effort was undertaken to clean up and document ADVISOR.

Since then, over 4500 individuals have downloaded one or more versions of ADVISOR, including all of the OEMs and major suppliers. About 2/3 of the users are from industry and 1/3 from universities. A shortlist of major ADVISOR users includes:

• DaimlerChrysler
• Ford Motor Company
• General Motors Corp.
• Delphi Automotive Systems
• Visteon and hundreds of others

SECTION-A:-

1.For EV_defaults in the file, if cargo mass is 500 kg with all other default conditions, can the vehicle travel for 45 km with the FTP drive cycle?

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

2. For the EV_defaults in the file, if cargo mass is 500 kg with all other default conditions, try changing the battery capacity and repeat the simulation.

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.7:- 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.

SECTION-C:-

3. Perform gradeability test with PRIUS_Jpn_defaults_in file and Compare your results in a table and conclude.

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 paramerte set as defalut.

Case 2:- SPEED=65mph=88.55Kmph and TIME=20 seconds. Other all paramerte set as defalut.

Case 3:- SPEED=75mph=120.7Kmph and TIME=20 seconds. Other all paramerte set as defalut.

Case 4:- SPEED=85mph=136.8Kmph and TIME=20 seconds. Other all paramerte set as defalut.

Case 5:- SPEED=95mph=152.9Kmph and TIME=20 seconds. Other all paramerte set as defalut.

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.
