Lithium-ion batteries have gained rapid popularity as an important means for the power sector. It is essential to model the battery in order to predict its behavior under various operating conditions to avoid any wrong operation and to safely manage to increase its life time. This paper introduces the most commonly used battery modelling techniques and their respective equivalent circuit models.
An algorithm is introduced that periodically monitors the state of charge (SOC) of a lead-acid battery without measuring the battery current and identifies whether it is above or below a calibrated threshold. Because a continuous SOC is not estimated, but the output is a discrete flag, the algorithm is said to carry out “discrete monitoring”. The equivalent circuit model of the battery consists of...
