Hybrid-Electric Vehicle Model in Simulink

Model of a hybrid-electric vehicle with system-level and detailed variants of electrical system.

Description

This file contains a hybrid-electric vehicle model built using Simscape, SimElectronics, SimDriveline, and SimPowerSystems that can be configured for system-level tests or power quality analyses. Model variants for the electrical, battery, and vehicle dynamics systems can be selected using configurable subsystems. A battery model created with the Simscape language is incorporated into the model. Supervisory logic is implemented with Stateflow. This model can be configured for hardware-in-the-loop testing.

Please read the README.txt file to get started.

To see the different variants included in this model, please watch the webinar, “Hybrid Electric Vehicle Modeling and Simulation“ http://www.mathworks.com/company/events/webinars/wbnr50682.html

Dear Steve, Thank you very much for the great model.
I wonder if the files and codes for connecting the model to the optimization algorithm would also be available?
I have a model of PHEV power-train which I want to integrate with an optimization algorithm, and I would like to examine what requirements I should care about in making such connections.
I will be grateful if such part is available and possible to be exchanged.

Thanks again.

Hello Steve,
I have been able to run this simulation but I have little experience with MATLAB, therefore I did not understand some of the information. What I will like to do though is connect a Solar Panel Model to this Model and see what the level in the state of charge (SOC) of the battery will be after couple of hours. Thanks in advance

@MD Rashidul -- did you run the startup_HEV_Model.m? It is looking for a library file that needs to be on your path.

[MD Rashidul]

Hi,

while running 'HEV_ParallelSeries_10b / HEV_SeriesParallel', I got the following error. Would you please suggest something?

Thanks.

Error:

Failed to load library 'HEV_Electrical_Lib' referenced by 'HEV_SeriesParallel/Electrical'

Caused by:
Unable to load block diagram 'HEV_Electrical_Lib'

I think the value of Motor_en in cruise mode(in the control stateflow, on the innermost level)should be '0', right?

[indra setiawan]

Dear Steve, i'm using R2011b.
And i found many errors. How i can open the model?
Thanks

[sajad anbaran]

would you please tell me that how i can obtain C code, if i succeed to run simulation.
regards.

Hello Steve,
i'm trying to run your system in parallel mode with different stateflow method.since i can't make change in electric subsystem, i put zero for generator required torque. by doing so i disabled Gen.however, when i want to run the simulation, vehicle is always in electric alone mode and doesn't switch to other modes.in other word, motor is the only working power source and engine speed becomes negative. but when i return Gen to the system, everything works nice. another issue is that do i need to change sun ring arrangement of the planetary gear to be operated in parallel HEV. please help me in these issues.

[KARTHIKEYAN]

steve i am using R2009b.can i run this file in that??? i'm facing lots of error in that.. please make me clear.

[Steve Miller]

Thanks for your comments, Abhishek.

The Vehicle Dynamics Full subsystem has aerodynamic drag included in it. The "Vehicle Body" block includes aerodynamic drag. The parameters for Drag Coefficient and Frontal Area are included in that calculation. See the documentation for that block: http://www.mathworks.com/help/toolbox/physmod/sdl/ref/vehiclebody.html. --Steve

[Abhishek Rai]

Hi Steve,
First of all I should congratulate you for your wonderful work.
While I was browsing through the "vehicle dnamics full" subsystem I found that you have not included the aerodynamic drag that you included in "Vehicle Dynamic Simple" subsystem.
I am curious to know tha answer.
Anticipating a soon reply.

[Andres RM]

Hello Steve, I must conglaturate you because of the model. I'd like to ask you, where did you find documentation to create vectorial controller?

Thanks.

[Max]

Good time. Can you send me the model code in C language?

Dear Steve,when I use this model to simulate a HEV system in matlab 2010b,it suggests that :Unable to load block diagram 'sdl_lib'.Can you tell me the reasons please?

Dear Steve,when I use this model to simulate a pure EV system in matlab 2010b,it suggests that :Unable to load block diagram 'sdl_lib'.Can you tell me the reasons please?

[Steve Miller]

Basil -- try the R2010b version that is included in the submission. It may work with R2010a with some warnings.

BearCat -- you can delete the gauges blocks. Road height can be added, but the model currently assumes flat roads.

Lucas -- I haven't parameterized the other battery types. I suggest pulling the battery model directly from the Simulink browser and entering the values there.

[Basil Aljorani]

can i run this model with 2010a.

[Lucas Fuentes]

Hi,
I am also interested in what BearCat asks. I need to be able to compare EVs to HEVs to conventional cars (internal combustion only).
Any tips on how to configure these types of vehicle?
Also, when I change the battery type from Ni-Hydride to anything but Li-Ion the simulation fails. I would be interested in comparing the different battery chemistries.
Thanks

[BearCat]

It cannot find gaugeslibv2.mdl when I start the simulation!

Does the simulation by any chance also consider fuel consumption depending on road topography?

These might be noob questions. But I hope you will answer anyway :-)

[curryxt ??]

Dear Steve, if I want to use this model to simulate a pure EV system, how should I configure the model? I will highly apprecialte your help.

[curryxt ??]

Thanks a lot. The above trouble has been removed. While, if I want to use this model to simulate a pure EV system, how should I configure the model?

[Steve Miller]

curryxt -- are you running release 2010a? Do you have all required products? The missing files you mention are part of the Simscape and SimElectronics installation.

[curryxt ??]

Sorry, when running, three models -elec_lib.mdl, fl_lib.mdl and 'nesl_utility.mdl cannot be founded ,also some blocks cannot get right parameter values.
