Does battery voltage depend on SoC?
The battery voltage depends on the SOC, and the error of voltage-based SOC estimation will increase at the beginning and end of the SOC range . Since the SOC rate is between 20% and 80%, the voltage variations in this range are very limited (Fig. 3) so that the battery voltage can be considered constant.
How to estimate battery SoC?
Direct techniques, such as OCV method is used to validate the SoC estimation results. KF method can estimate battery SoC, even when the states are affected by external perturbations. This method can estimate battery SoC online in real time with high accuracy.
What is the relationship between voltage and SOC?
The relationship between voltage and SoC is not linear. This means that a slight change in voltage can represent a significant change in SoC at specific points of the discharge curve. For instance, a battery's voltage may remain relatively stable between 40% and 80% charged, but it can drop sharply as it approaches 20% or below.
Does SoC affect the internal resistance of a battery?
Additionally, SOC affect the internal resistance of the battery. When SOC decrease to 70 %, the effectiveness of estimating internal resistance gradually diminishes in this study because of the reduction in the size of the covariance matrix in the algorithm, and the estimated internal resistance values only fluctuated slightly.
