Summary:

Lithium-ion power battery has become one of the main powersources for electric vehicles and hybrid electric vehicles becauseof superior performance compared with other power sources. In orderto ensure the safety and improve the performance, the maximumoperating temperature and local temperature difference of batteriesmust be maintained in an appropriate range. The effect oftemperature on the capacity fade and aging are simply investigated.The electrode structure, including electrode thickness, particlesize and porosity, are analyzed. It is found that all of them havesignificant influences on the heat generation of battery. In thisstudy, the modeling done by CREO parametric software and analysisdone by CFD tool. The model designed with different type of heatpipe shapes and analyzes the heat pipe with different mass flowinlets (30, 40& 50L/min). In this study, CFD analysis todetermine the pressure, velocity, heat transfer coefficient, massflow rate and heat transfer rate for the different designs of heatpipe and different mass flow inlets and thermal analysis todetermine the temperature distribution and heat flux for two typesof phase change materials (RT50 and Li Fe PO4). The results ofthe CFD analysis compare the heat transfer rate of the threedifferent kinds of the cooling system design Such as straight type,box type and bend type heat pipes. By observing the CFD analysisresults, the mass flow rate, heat transfer rate, heat transfercoefficient values are increased by increasing the mass flow inletsand heat transfer rate more at box type heat pipes. By observingthe thermal analysis results, the heat flux value is more forlithium ion phosphate phase change material than RT50 phase changematerial at box type heat pipes
