Li-ion cell model

brucelee2

Hi all,

Im currently involved in Li-ion cell balancing methods. I have come to a time where i need a model of a li-ion cell (to have a voltage profile with State of charge). Im aware of a schematic to do this(other suggestions are welcome). I now need to make a model in spice. Can someone briefly describe to me the process for doing so? 

Thanks in advance,

  • Hi Bruce,

     you can try it by using a lookup table. Therefore you only need a graph of the open circuit voltage over SOC. The cell type should match with your "planned" Li-ion cell in capacity and cell chemistry.

    If its allowed to tell, I'm interested in which kind of cell balancing do you use (active or passive)?
