In this study, three active, passive, and hybrid thermal management systems are applied to a lithium battery module with industrial specifications, i.e., Tesla battery module, and the optimal conditions are extracted. The thermal and electrochemical behavior of battery cells is modeled using the quasi-two-dimensional approach by Newman’s method. The effects of inter-cellular distance on the maximum temperature and on the temperature distribution in the pack as the target variables are thoroughly investigated. A suitable range for the above distances is then determined in order to reduce the overall cooling power and the expected thermal performance of the pack. The results of temperature... 

Lithium-ion batteries have the ability to store a significant amount of energy and work at high power, which has led to the wide spread of their use in various industries. In high-power applications, battery heat management increases lifespan, safety, and reduces battery power loss. In this study, the heat management of a very common and widely used 18650 battery using multi-layered phase change material has been investigated. The reason for using multiple layers is that each phase change material has its own weaknesses in addition to its advantages. It is expected that with the proper use of several phase change materials in the thermal management system, the materials will reduce the...
