[TRNSYS-users] batteries models

[David Bradley]

Maria,
  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.
Best,
 David
