Precise knowledge of this value is vital for designing battery systems for automotive applications. Internal resistance of a cell was determined by current step methods, AC (alternating current) methods, electrochemical impedance spectroscopy and thermal loss methods. The outcomes of these measurements have been compared with each other. If charge or discharge of the cell is limited, current step methods provide the same results as energy loss methods.<\/jats:p>","DOI":"10.3390\/s100605604","type":"journal-article","created":{"date-parts":[[2010,6,3]],"date-time":"2010-06-03T11:37:04Z","timestamp":1275565024000},"page":"5604-5625","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":258,"title":["Comparison of Several Methods for Determining the Internal Resistance of Lithium Ion Cells"],"prefix":"10.3390","volume":"10","author":[{"given":"Hans-Georg","family":"Schweiger","sequence":"first","affiliation":[{"name":"Continental AG, Business Unit Hybrid and Electric Vehicles, Sickingenstrasse 42-46, 10553 Berlin, Germany"}]},{"given":"Ossama","family":"Obeidi","sequence":"additional","affiliation":[{"name":"Continental AG, Business Unit Hybrid and Electric Vehicles, Sickingenstrasse 42-46, 10553 Berlin, Germany"}]},{"given":"Oliver","family":"Komesker","sequence":"additional","affiliation":[{"name":"Continental AG, Business Unit Hybrid and Electric Vehicles, Sickingenstrasse 42-46, 10553 Berlin, Germany"},{"name":"University of Applied Sciences Brandenburg, Magdeburger Strasse 50, 14770 Brandenburg, Germany"}]},{"given":"Andr\u00e9","family":"Raschke","sequence":"additional","affiliation":[{"name":"Continental AG, Business Unit Hybrid and Electric Vehicles, Sickingenstrasse 42-46, 10553 Berlin, Germany"},{"name":"Georg Agricola University of Applied Sciences, Herner Strasse 45, 44787 Bochum, Germany"}]},{"given":"Michael","family":"Schiemann","sequence":"additional","affiliation":[{"name":"Continental AG, Business Unit Hybrid and Electric Vehicles, Sickingenstrasse 42-46, 10553 Berlin, Germany"}]},{"given":"Christian","family":"Zehner","sequence":"additional","affiliation":[{"name":"University of Applied Sciences Brandenburg, Magdeburger Strasse 50, 14770 Brandenburg, Germany"}]},{"given":"Markus","family":"Gehnen","sequence":"additional","affiliation":[{"name":"Georg Agricola University of Applied Sciences, Herner Strasse 45, 44787 Bochum, Germany"}]},{"given":"Michael","family":"Keller","sequence":"additional","affiliation":[{"name":"Continental AG, Business Unit Hybrid and Electric Vehicles, Sickingenstrasse 42-46, 10553 Berlin, Germany"}]},{"given":"Peter","family":"Birke","sequence":"additional","affiliation":[{"name":"Continental AG, Business Unit Hybrid and Electric Vehicles, Sickingenstrasse 42-46, 10553 Berlin, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2010,6,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"A1128","DOI":"10.1149\/1.1914744","article-title":"Thermal behavior of small nickel\/metal hydride battery during rapid charge and discharge cycles","volume":"152","author":"Araki","year":"2005","journal-title":"J.
