The user manual says to that HPPC data can be inputted into the parameter estimation tool to get an estimate for internal resistances\/capacitances, however the Battery Modeling course in the Ansys learning hub states that this is only accurate at one operating point. My main questions are:<\/p>\n<ul>\n<li>If we collect our HPPC data at various temperatures\/SOC&#8217;s, does Ansys create a lookup table for the different operating points? If so, how reliable are Ansys&#8217;s interpolations\/extrapolations of these operating points? Ideally, we&#8217;d have internal battery parameters as functions of SOC and temperature.<\/li>\n<li>I&#8217;ve noticed mention of a &#8220;state-space model&#8221; crafted from Electrochemical Impedance Spectroscopy data. Is this relevant to our use case for modeling various operating conditions?<\/li>\n<\/ul>\n<p>Thank you for your help!<\/p>\n","protected":false},"template":"","class_list":["post-317353","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["11752","5976"],"_bbp_author_ip":["23.206.193.146"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["381"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["317353"],"_bbp_forum_id":["27792"],"_bbp_engagement":["5976","11752"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["317781"],"_bbp_last_active_id":["317781"],"_bbp_last_active_time":["2023-11-15 12:09:37"]},"test":"evansandovalberkeley-edu"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/317353","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/317353\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=317353"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
