Which method is used to estimate battery Soh based on releasable capacity?

Direct measurement approach The battery internal resistance and available capacity are critical parameters for the battery SOH assessment. The Coulomb counting method is a useful method for capacity estimation. In Ref. , the Coulomb counting method employed to estimate the SOH is evaluated by the maximum releasable capacity.

How to estimate SOC of lithium battery based on aekf?

A new method to estimate SOC of LIB based on AEKF was proposed in Ref. . A simple optimization algorithm is applied to update the battery aging model, and the SOC with different aging batteries was estimated by AEKF. The results showed that the SOC error is less than 4%.
