Hysteresis is when the properties of a material depends on the path used to attain a certain state. For batteries it depends on the charge\/discharge sequence taken to reach a state of charge (SOC), and the property affected is the OCV.<br>The NiMH battery is significantly affected by OCV hysteresis. The hysteresis window is large, a single OCV value can represent a span of SOCs as wide as 70% of the total SOC window. As a consequence, NiMH battery models without a proper description of the OCV hysteresis often render inaccurate results when simulating the behavior of systems during dynamic charge\/discharge patterns. In this study different ways of modeling the OCV hysteresis is compared in a lumped model setting on different dynamic data sets from NiMH battery systems.<\/p>\n\n\n\n<p><a href=\"http:\/\/nordbatt.org\/2019\/posters\/\">Full list of posters<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Author: Jenny B\u00f6rjesson Ax\u00e9n Title: Modeling of OCV hysteresis in the NiMH battery system Affiliation: Royal Institute of Technology, KTH &hellip; <a href=\"http:\/\/nordbatt.org\/2019\/blog\/jenny-borjesson-axen-modeling-of-ocv-hysteresis-in-nimh-battery-system\/\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">Poster: Modeling of OCV hysteresis in the NiMH battery system<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"nordbatt-wide.php","format":"standard","meta":{"footnotes":""},"categories":[52,59],"tags":[],"class_list":["post-1671","post","type-post","status-publish","format-standard","hentry","category-nordbatt2019","category-poster-presentation"],"_links":{"self":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1671","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/comments?post=1671"}],"version-history":[{"count":3,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1671\/revisions"}],"predecessor-version":[{"id":1714,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/posts\/1671\/revisions\/1714"}],"wp:attachment":[{"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/media?parent=1671"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/categories?post=1671"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/nordbatt.org\/2019\/wp-json\/wp\/v2\/tags?post=1671"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
