Performance measurement of Li - Ion batteries under different usage conditions

Electric Vehicles is one of the leading technologies of our time. Electric vehicle technology is an area of intensive research and development, academic interest, and also public interest. Lithium-ion batteries have important advantages such as high voltage, high energy density, long service life and memory effect. Because of these advantages, Li-ion batteries, which are other battery technologies, are more widely used in electric vehicles compared to nickel-based batteries and sodium-based batteries. In this thesis, the state of lithium ion batteries during charging and discharging processes are examined. The charge and discharge curves of the batteries under constant current are examined. At the same time, the dynamic nature of the internal resistance of lithium ion batteries has been investigated. Keywords: Electric Vehicles, Electric car technology, Labview, Lithium Ion Battery
