摘要: Lithium-ion is used in battery electric vehicles as an effective and efficient energy storage medium. The density life cycle of are better than lead-acid batteries. But for batteries, like every other battery, when operating a high discharge current which causes increase temperature. This temperature degradation the performance available electrical capacity battery. An experimental method was carried out to determine effect discharging 18650 cells surface first measurement on cell by installing three sensors measure distribution each installed at 16mm (point A), 32mm B) 48mm C) from positive end initial treatment before test charging up voltage 4,2Vdc, then drained 2,7Vdc. Constant currents applied i.e. 3.5A, 7.5A, 11A, 15A, respectively. second module consisting 35 arranged 7 series 5 parallel (7S5P). Each sensor center B). with put middle or module. Before current, charged 29.4Vdc. modules 20A, 25A, 30A, result time shows that 15A produces highest compared 11A. point A has lower tendency points B C. D direction arrangement higher temperatures points. condition indicates concentration arrangement.
