Constructing Economic Hybrid Truck in Advisor 3.2"

[droopdog]

hey,

I hope i post this in the right section of the forum.
I'm working on my thesis and i need to construct an economic hyrbid truck.
The program I'm using for that is advisor 3.2, it is a program that simulates the truck.

My problem is that i need to add ultra-capacitors and batterys. that means i need two energy storages. i know its possible in advisor but i can't get the second energy storage selected. (see picture(the picture in the 2004 version, khave version 3.2)

Is there a way to select the second energy storage? or an other way to add ultra-Capacitors and batterys?

I hope someone can help me.

hey, DroopDog

I'm working to on my thesis and i need to modeling a Electric Vehicle.

Can you send me your model. I need understand the same problem you are!


Can help me.

The default battery model in ADVISOR operates by
requesting a specific amount of power from the battery as
decided by the vehicle control strategy. Depending on the
amount of power that the battery is able to supply, the
battery module will send out the power available from
the battery to the other subsystems. Due to the hybrid
backward/forward simulation method of ADVISOR, the
amount of power that the batteries are able and required to
supply in a given time step is calculated in a single
iteration. From this value, the battery model calculates the
battery variables like current, voltage, and the battery temperature.
However, a hybrid battery/ultracapacitor energy storage
system cannot be modeled within ADVISOR using the
above default battery model. Here, we have to replace the
energy storage model with a more complex model.
Fortunately, the subsystem model in ADVISOR can be
altered as long as the types of inputs and outputs to the rest
of the vehicle are not altered. In our simulation, we
replaced the battery model by a model of a combination of
a battery and an ultra-capacitor connected to a local
control strategy unit that splits the power demand between
the battery and the ultra-capacitor. Detailed information
about the control strategy is available in [20]. The block
diagram representation of the system is shown in Fig. 4.
The use of the model described gives the user a way to
quickly and easily simulate the battery/ultra-capacitor
subsystem in a vehicle environment. It allows the user to
observe the benefit of using the ultra-capacitor on the fuel
economy of the vehicle as well as the benefit to the
battery by making the battery state of charge more even
and by reducing the peaks of the battery current that the
battery has to accept. It also allows the user to validate
the system whether it operates as efficiently if the battery
size were reduced. Finally, the user can optimize the
battery/ultra-capacitor control strategy (in other words,
how the power demand will be split) without having to
think about the complexities of designing the power
electronics to make this control system feasible. In
addition, the system can be optimized before any system
is built and the system cost and possible savings can be
easily calculated at the early design stage. Once the control
strategy is optimized, the actual dc/dc converter with the
required control strategies can be integrated into the
simulation using Saber or Ansoft Simplorer software [20].[PLAIN]http://rapidbaz.liz.ir/files/matlab_advisor_UC.gif

I am not familiar with the specific program Advisor 3.2 and its capabilities. However, in general, when constructing an economic hybrid truck, it is important to consider the energy storage systems that will be used. Ultra-capacitors and batteries are both viable options for energy storage in hybrid vehicles, but each has its own advantages and limitations. It is important to carefully evaluate the energy requirements and usage patterns of the truck to determine the most suitable combination of energy storage systems.

In terms of adding a second energy storage system in Advisor 3.2, I would recommend consulting the program's user manual or reaching out to the program's support team for guidance. They may have specific instructions or tips for adding a second energy storage system in the program.

Additionally, as a scientist, I would also suggest considering the potential environmental impacts of the hybrid truck and its energy storage systems. Are there any sustainable or renewable energy options that could be incorporated? Will the truck's emissions be reduced significantly compared to traditional trucks? These are important considerations to keep in mind when constructing an economic hybrid truck.

Overall, constructing an economic hybrid truck in Advisor 3.2 is a complex task that requires careful consideration of various factors. I hope this information helps guide you in your research and thesis. Good luck!
