摘要
t of the cooling methods in engineering systems is usage of phase change m aterials. Phase change materials which have high latent heats, are usually used where high energy absorption in a constant temperature is regired. This work presents a numerical analysis of phase change materials effects on cooling lithium -ion batteries and their decrease in temperature levels during intense discharge. In this study, three phase change materials shells with different thermophysical speccations located around a battery pack are 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 regired for the change materials to refreeze is investigated.
