Inconsistent battery voltage data can be used to estimate the state of health of the battery. The dual timescale Kalman filtering algorithm based on the reference difference battery model is derived. A compensation algorithm for the voltage difference of the RC circuit in the battery difference model is proposed.
Cell difference model In series-connected batteries, the internal resistance and the maximum available capacity primarily affect the voltage response difference and correspond to the SOH of the battery. Therefore, assessing the difference in battery voltage response is a viable means of evaluating battery health.
Due to limitations (e.g., production techniques, tolerance levels, and material defects ), there may be subtle differences in parameters such as capacity, internal resistance, and self-discharge rate between batteries. In practice, these inconsistencies manifest in the inconsistent voltage responses of series-connected cells.
Estimating the battery state of health using voltage differences improves the speed and accuracy of the algorithm. The state-of-health (SOH) of battery cells is often determined by using a dual extended Kalman filter (DEKF) based on an equivalent circuit model (ECM).
The results showed that using the voltage differences between individual cells and the inconsistency of parameters to estimate the health status of multiple battery cells could accelerate the running speed of the algorithm, reduce the algorithm cost, and achieve good stability. The paper is structured as follows.
