ADVISOR (Advance Vehicle Simulator)

ADVISOR TOOL developed in 1994 by the National Renewable Energy Laboratory (NREL) Software and "Advanced Vehicle Simulator". ADVISOR is a MATLAB or Simulink based simulation program for rapid analysis of the performance and fuel economy of light and heavy-duty vehicles with conventional (gasoline/diesel), hybrid-electric, full-electric, and fuel cell powertrains. New features are developed under the title "Advanced Vehicle Simulator". The TOOL allows users to access the effect of changes in vehicle components such as motors, batteries, catalytic converters, climate control systems and alternative fuels. Other modifications that might effect fuel economy, performance or emissions. It is set of models, data and script text files for use with matlab and simulink.

The Benefits of using ADVISOR:

1. Learn about how conventional, hybrid or electric vehicles use energy throughout thir drivetrains

2. Estimate the fuel economy of vehicles that has not yet been built.

3. Compare relative tailpipe emissions produced on a number of cycles.

4. Evaluate an energy management strategy for your hybrid vehicle fuel converter.

How to start ADVISOR Tool:

1. Launch matlab and first set default location folder to the advisor.

2. Now in the command window of matlab type "advisor" and press enter

3. A new window will open and then set "metric" for unit and start ADVISOR.

4. It will launch in a new window.

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.

Considering the case for typical EV, lets simulate EV_defaults_in an electric vehicle with following specifications:

1. Now changing the cargo mass to 500 kg.

2. Change in the total mass of the vehicle can be seen.

3. Clicking on the continue button after that a new window simulation parameter will be pop-up.

4. In simulation parameter window change drive cycle to CYC_FTP by selecting the drop down menu.

5. Below that we will see no. of cycles from here we can change the drive cycle.

Increasing no.of drive cycles to 2

6. After pressing the RUN button, the simulation will start and it will show results in a new window.

Result with 2 Drive Cycles

7. The distance travelled by the vehicle in 2 drive cycle is 35.5 km. used almost 81% of SOC

Increasing no.of Drive Cycle to 3

Result with drive cycle 3

The distance travelled by the vehicle in 3 Drive Cycles is 41.4 km. Used completely 100% of SOC.

The minimun distance travelled by the car is 17.8 km with a drive cycle CYC_FPT. Whereas maximum distance travelled by the car is 41.4 km which consumes 100% of battery in 3 drive cycles. Hence the vehicle cannot travel 45 km in a single charge.

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 from energy storage which will be open in first.

" # of mod V nom" describes the battery capacity, so we will change the module number of batteries from the first box and we will see that changes in voltage and weight of the battery.

A new simulation parameter window will open here we will change the drive cycle to 2 to 3, and run the simulation.

After completing the simulation, we will see the result window where we observe the change in distance of vehicle travel.

We can repeat the simulation by changing the battery module and the drive cycle.

1. The energy storage system with 27 modules and 2 drive cycles:
