Given the nonlinear dynamic system of the lithium-ion battery, the parameters of the second-order RC equivalent circuit model were calibrated and optimized using a nonlinear least squares algorithm in the Simulink parameter estimation toolbox. A comparison was made between this finite difference extended Kalman filter (FDEKF) and the standard extended Kalman filter in the SOC estimation. The results show that the model can essentially predict the dynamic voltage behavior of the lithium-ion battery, and the FDEKF algorithm can maintain good accuracy in the estimation process and has strong robustness against modeling error.<\/jats:p>","DOI":"10.1155\/2014\/348537","type":"journal-article","created":{"date-parts":[[2014,4,3]],"date-time":"2014-04-03T17:04:12Z","timestamp":1396544652000},"page":"1-10","source":"Crossref","is-referenced-by-count":20,"title":["Estimation of State of Charge for Lithium-Ion Battery Based on Finite Difference Extended Kalman Filter"],"prefix":"10.1155","volume":"2014","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4843-103X","authenticated-orcid":true,"given":"Ze","family":"Cheng","sequence":"first","affiliation":[{"name":"School of Electrical Engineering & Automation of Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jikao","family":"Lv","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering & Automation of Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yanli","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering & Automation of Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhihao","family":"Yan","sequence":"additional","affiliation":[{"name":"School of Electrical Engineering & Automation of Tianjin University, Tianjin 300072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"crossref","first-page":"272","DOI":"10.1016\/j.jpowsour.2012.10.060","volume":"226","year":"2013","journal-title":"Journal of Power Sources"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apenergy.2008.11.021"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.energy.2012.01.009"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpowsour.2004.02.031"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpowsour.2004.02.032"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpowsour.2004.02.033"},{"issue":"4","key":"8","doi-asserted-by":"crossref","first-page":"2016","DOI":"10.1016\/j.apm.2012.04.029","volume":"37","year":"2013","journal-title":"Applied Mathematical Modelling"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-7753(02)00194-5"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2011.2132812"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpowsour.2011.10.013"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpowsour.2011.01.005"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpowsour.2003.12.001"},{"issue":"11","key":"15","doi-asserted-by":"crossref","first-page":"2053","DOI":"10.1016\/S0005-1098(97)00127-1","volume":"33","year":"1997","journal-title":"Automatica"}],"container-title":["Journal of Applied Mathematics"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/348537.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/348537.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/jam\/2014\/348537.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,22]],"date-time":"2017-06-22T06:57:44Z","timestamp":1498114664000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/jam\/2014\/348537\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":13,"alternative-id":["348537","348537"],"URL":"https:\/\/doi.org\/10.1155\/2014\/348537","relation":{},"ISSN":["1110-757X","1687-0042"],"issn-type":[{"type":"print","value":"1110-757X"},{"type":"electronic","value":"1687-0042"}],"subject":[],"published":{"date-parts":[[2014]]}}}
