Abstract
Battery systems, battery modules, and a method for cooling a battery module are provided. The battery module includes a first battery cell, and a first cooling fin having a first panel portion and first and second rail portions that are disposed on first and second ends, respectively, of the first panel portion. The first battery cell is disposed adjacent to a first side of the first panel portion. The first and second rail portions have a thickness greater than the first panel portion. The first cooling fin conducts heat energy from the first battery cell into the first cooling fin to cool the first battery cell. The battery module further includes first and second conduits extending through the first and second rail portions, respectively, that receive a fluid that flows through the first and second conduits to conduct heat energy from the first cooling fin into the fluid.
