The　consistency　of　the　power　battery　is　a　key　issue　affecting　battery　performance　and　battery　life.　In　order　to　improve　the　inconsistency　of　the　power　battery,　this　paper　proposes　a　reasonable　static　sorting　method.　Firstly,　make　unqualified　recheck　operation　of　battery　core　parameters.　Secondly,　based　on　the　ISODATA　clustering　algorithm,　a　new　method　for　calculating　the　distance　between　data　is　defined,　and　in　order　to　carry　out　consistent　sorting　of　the　battery.　The　improved　ISODATA　algorithm　provides　a　way　to　solve　cell　consistency　problems.　It　does　not　rely　on　the　number　of　manually　defined　clusters,　and　adaptively　defines　the　number.　According　to　our　redefined　distance　standard,　it　can　reasonably　represent　the　influence　relationship　between　the　parameters　of　the　cell　data.　Finally,　by　comparing　with　k-means　and　ISODATA　experiments,　the　results　show　that　this　sorting　method　can　effectively　sort　the　given　cell　parameters,　and　the　effect　is　better.
