Lithium-ion batteries are extensively used in various renewable sources such as energy storage systems, electric vehicles, and portable vehicles due to their properties. However, since they significantly affected by ambient temperature, lifetime safety issues general negatively affect electrical performance. In order ensure that achieve optimum potential, it is necessary understand the interaction between charge discharge rates temperature changes very well. this study, characteristics of 26650 lithium-ion were analyzed series under different environmental conditions rates. To relationship temperatures battery performance, Newman, Tiedemann, Gu, Kim (NTGK) evaluated effectiveness previously models predicting these effects. The Ansys Battery Ntgk model was predict behavior voltage variations outdoor conditions. four (273 K, 283 298 318 K) (0.5C, 1C, 1.5C, 2C) investigated study thermal variations. mesh independence carried out detail at beginning analysis validate simulation results. results show time reduced increased internal resistance electrochemical side reactions. 1S1P design exhibits a maximum 303.2 K an 273.15 336.7 318.15 while 2S1P even higher 341.3 indicating compound heat buildup occurs connections.
