TL;DR: In this article, a method of assessing multicell battery health in a battery control device includes: obtaining (i) a measured indicator value corresponding to an indicator battery parameter, and (ii) measured first input value correspond to a first input parameter; determining whether a difference between the measured indicator values and the expected indicator value exceeds a predefined cell loss threshold; and when the difference exceeds the predefined threshold, generating a cell loss alert.
Abstract: A method of assessing multicell battery health in a battery control device includes: obtaining (i) a measured indicator value corresponding to an indicator battery parameter, and (ii) a measured first input value corresponding to a first input parameter; obtaining, based on the first input value, an expected indicator value corresponding to the indicator battery parameter; determining whether a difference between the measured indicator value and the expected indicator value exceeds a predefined cell loss threshold; and when the difference exceeds the predefined cell loss threshold, generating a cell loss alert.
