AB - One of the cooling methods in engineering systems is usage of phase change  materials. Phase change materials or PCMs, which have high latent heats, are  usually used where high energy absorption in a constant temperature is  required. This work presents a numerical analysis of PCMs effects on cooling  Li-ion batteries and their decrease in temperature levels during intense  discharge. In this study, three PCM shells with different thermo-physical  specifications located around a battery pack is examined. The results of each  possible arrangement are compared together and the best arrangement leading  to the lowest battery temperature during discharge is identified. In  addition, the recovery time for the system which is the time required for the  PCMs to refreeze is investigated.
