A design for the thermal management of the media used for packing Li-ion batteries used in hybrid and electric vehicles has been developed. The design satisfies all thermal and physical issues relating to the battery packs used in vehicles such as operating temperature range and volume, and, should increase battery life cycle and charge and discharge performances. Particular attention was devoted to the thermal management of batteries operating in extreme temperature conditions, that is, from -50ºC to +50°C, with desired operating conditions held between 20°C and 30°C. The method of cooling/heating here could be thought akin to a heat sink approach with heat removed or added using water. This current work is a series of simulations used to give sound indications for the design and assembly of a prototype.
