Aviation Alkaline Storage Battery State-of-health Estimation Based on the EP-weighted Static SOR Algorithm

Abstract

In this paper, we studied the current situation and problems of the aviation alkaline battery maintenance in China, and discussed the application of static SOR (State of Running) algorithm in aircraft alkaline storage battery state-of-health (SOH) estimation and its defects. Based on the static SOR algorithm, weighting according to the time segments was proposed and introduced the absolute value in difference monomer voltage and overall average (DFM). It compensates for the ambiguity of the static SOR algorithm of weighting function and solves the problem that the static SOR algorithm cannot identify the monomer whose voltage does not change being close to a certain value, or even be mistaken for monomer with good operational performance.
