Abstract
As today’s trend, the electrical vehicles are coming in market; EV’s are capturing the big share in automobile sector. The Battery is power source for electrical vehicle which giving electric power to motor. In electric battery, electric energy is stored in the chemical form. The battery is charged to store energy and discharged to get energy back. While working of electrical vehicle the battery continuously supplies energy to electric motor by doing chemical reaction in it. During charging and discharging, the heat is generated in the battery due to chemical reaction and resistance; it causes heating of the battery cells continuously. But, cooling of heated cells is necessary to maintain it in required temperature limit (15 to 35 degree celsius). Currently, there is a lack of Battery Thermal Management System (BTMS) which has desired effect on battery temperature. Presently, coolant is used for cooling the battery and it gives good results at initial period, but as time passes, the coolant also gets heated. Due to this, coolant is not able to absorb heat from the battery cells further. So, there is need of system which can absorb heat from coolant for efficient working of BTMS. Currently, there are various methods of cooling of battery which include air cooling, liquid cooling, Phase change materials, etc. As per literature review, liquid cooling has high efficiency, so decided to consider liquid cooling method for the further analysis of the proposed work. Analysis of Cylindrical Lithium-ion Battery Pack is carried out to maintain the temperature in required range, prevent battery deterioration by managing heat generated, stabilize the temperature dissipation and prevent the uncontrolled pressure in the cells and battery pack. Using the Star CCM+ software, CFD analysis is performed with a selection of boundary conditions. For the analysis, two different models of similar battery pack are used by varying size of cooling channels. The cooling performance of battery pack is increased in present work study.
