Battery Capacity Estimation Methodology and Validation Using IT Power Data

With a view to propose a generic chemistry agnostic battery capacity estimation approach, development of a modified Coulomb Counting approach is under way. The modified approach will enhance the conventional approach by overcoming limitations. So far, we have modified the approach by including features that overcome the issues related to measurement inaccuracy/noise and self-discharge. Further improvements in the developed approach is under progress with an aim to ensure higher estimation accuracy by overcoming the issues related to inaccurate knowledge of initial state of charge and changing coulombic efficiency.
