Abstract

In this paper; a finite element model for the heat transfer inside an automotive lithium ion cell with Modelica is developed. Convective cooling with several coolants is examined. With the help of the cell model; the effectiveness of several coolants are investigated. As coolants air; 25 and 38 % (v/v) aqueous propylene glycol; and a silicone oil are used.
