<p class=MsoNormal>Dimas,<br>
I am not sure that changing the cell voltage is valid. I think that the
Shepherd model assumes a certain shape to the battery's charge / discharge
curve that is inherent to lead acid batteries and not as valid to other battery
types. Someone please correct me if I am wrong about that.<br>

<p class=MsoNormal style='margin-bottom:12.0pt'>Dear David and Maria,<br>
<br>
I'm also doing simulation that required different type of battery from the
existing battery type available in TRNSYS library,<br>
I need to simulate 12V battery bank, that consist of 4 @12V 100Ah battery. Type
47b in TRNSYS library have a default voltage value of 2,5V each cell, Can I
simply change this value? or do I need to make some other modification for this
component? <br>
David, I'd like to read the paper you've offered to maria, would you send me
also?<br>
<br>
Thank you very much<br>

You are correct that the battery models in TRNSYS are for lead-acid
cells. I was directed to a paper some years ago that suggested a method for
modeling lithium-ion batteries. The method comes down to curve fitting the data
that you get from a manufacturer's catalog into a few polynomials. I had a hard
time following the some parts of the paper and never got a chance to implement
the model but it seemed to me as though the method could be extended to other
battery types. I'll forward you the paper in a separate email. If anyone else
has seen some modeling research in this area, I'd be quite interested in
hearing about it to improve on the existing battery models.<br>
