Future Trends and Challenges in Mechanical Engineering-2024 (FTCME-2024)

In the rapidly evolving realm of energy storage, lithium-ion batteries have emerged as a transformative force, powering everything from portable gadgets to electric vehicles. However, their widespread adoption has brought to the fore the critical challenge of accurately estimating their State of Charge and State of Health. This research delves into the intricacies of these estimations, shedding light on the multifaceted methodologies that have been proposed over the years. Through a meticulous examination, we unravel the strengths and limitations of each technique, from Coulomb Counting's susceptibility to drifts to the adaptability of Kalman Filtering techniques and the complexity of impedance-based methods.
