Abstract

A battery module is described. The battery module includes a plurality of battery cells; a plurality of cooling fin assemblies, each cooling fin assembly positioned between two battery cells, the cooling fin assemblies comprising at least one cooling fin and a foot on at least one side of the cooling fin assemblies, the foot having a bottom and interlocking profiles on each end, the interlocking profiles on adjacent feet of the cooling fin assemblies interlocking the feet and forming a surface; and a heat sink contacting the surface of the interlocked feet. A method of cooling a battery module is also described.
