Numerical investigation on improvement of cooling system based on heat pipe for ‎LCO battery by using NTGK model

Nowadays, due to environmental concerns and the hope of limiting the phenomenon of pollution in mega-cities, the development of electric vehicles is one of the priorities of the modern industrial world. Lithium batteries are the main type of batteries used in electric cars. Temperature is one of the most effective parameters on the performance of these batteries because it can change their chemical behavior. Due to the necessity of battery operation in a suitable temperature range and with uniform temperature distribution, it is necessary to adopt a suitable and optimal cooling method with efficiency and reliability at all three levels of cell, module, and battery pack. One of the passive methods for thermal management in batteries is the use of a heat pipe. The purpose of this research is to use a new arrangement for the heat pipe in a battery module and study its temperature effects with the help of 3D thermal model simulation and an electrochemical model (NTGK) to simulate this system. The results of this study indicate that this new arrangement can improve the temperature uniformity distribution of the battery module by 4.1%.
