Description

Battery modeling has been introduced in the EM solver in order to simulate battery cells under normal use conditions as well as during abusive scenarios where the battery cells are damaged and shorts can occur. The thinness of the different components of a unit cell (anode/cathode, separator, current collectors) makes battery modeling a challenge for each of the different physics involved (EM, mechanical, thermal) especially in impact and short cut scenarios. On the EM side, the challenge will consist in modeling the chemical reaction of ions moving in electrolyte.  The EM solver uses the so called Randles circuits i.e equivalent circuit models  to represent battery electrochemical reactions.
