Matlab and simulink

  1. Aug 12, 2008 #1

    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 cant get the second enery 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].
