Abstract: This study presents an in-depth analysis of ageing and temperature effects in lithium-ion batteries, as well as an investigation into cell balancing issues. The ageing effect, encompassing capacity fade and impedance rise over time, is scrutinized through experimental and computational approaches. Through controlled cycling tests under various temperature conditions, the impact of temperature on battery ageing is evaluated, revealing accelerated degradation at higher temperatures. Additionally, a comprehensive battery model integrating ageing and temperature effects is developed to simulate the long-term behavior of lithium-ion cells. Furthermore, the study addresses cell balancing challenges, essential for maintaining uniform cell voltages within battery packs to enhance performance and longevity. Various cell balancing techniques, including passive and active methods, are reviewed and compared in terms of effectiveness and implementation complexity. Additionally, novel algorithms for dynamic cell balancing are proposed to mitigate voltage deviations among cells during operation. Overall, this thesis contributes to a better understanding of aging and temperature effect in lithium and battery, here we can see if we add aging and temperature effect battery charging time and voltage increase our time, on the other hand discharging time and voltage decrease.
