Cylindrical Geometry Energy Storage Cooling
Keywords: Battery Cooling, Liquid/heat pipe battery module cooling, High discharge rate battery cooling
This presentation will demonstrate the thermal performance of an innovative assembly for cooling cylindrical battery cells that are generating heat during rapid charge and discharge cycles. The standard practice for cooling cylindrical cells is blowing cooling air between the cylinders to remove the heat. By replacing the air with low cost heat pipes and a small amount of electrically non-conductive heat transfer fluid, the temperature excursions of the cells can be significantly reduced. The presentation will show the use of CFD modeling of the battery assembly. The simulation will show the difference in cooling performance of the battery assembly when cooled with air and the proposed heat pipe/fluid cooling array. This cooling technology has application when batteries are stressed beyond their normal limits during very high charge and discharge rates.
