The currently widely used indirect liquid cooling imposes disadvantages of the higher thermal resistance and coolant leakage which has diverted the attention to the direct liquid cooling for the thermal management of batteries. The present study conducts the experimental investigation on discharge and heat transfer characteristics of lithium-ion battery with direct liquid cooling for the thermal management. The 18,650 lithium-ion cylindrical battery pack is immersed symmetrically in dielectric fluid. The discharge voltage and capacity, maximum temperature, temperature difference, average temperature, heat absorbed, and heat transfer coefficient are investigated under various conditions of discharge rates, inlet temperatures, and volume flow rates of coolant. The operating voltage and discharge capacity are decreasing with increase in the volume flow rate and decrease in the inlet temperature for all discharge rates. At the higher discharge rate of 4C, the lowest battery maximum temperatures of 60.2 \u00b0C and 44.6 \u00b0C and the highest heat transfer coefficients of 2884.25 W\/m2-K and 2290.19 W\/m2-K are reported for the highest volume flow rate of 1000 mLPM and the lowest inlet temperature of 15 \u00b0C, respectively.<\/jats:p>","DOI":"10.3390\/sym14102126","type":"journal-article","created":{"date-parts":[[2022,10,12]],"date-time":"2022-10-12T22:45:29Z","timestamp":1665614729000},"page":"2126","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Experimental Study on Dielectric Fluid Immersion Cooling for Thermal Management of Lithium-Ion Battery"],"prefix":"10.3390","volume":"14","author":[{"given":"Jeong-Woo","family":"Han","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Dong-A University, 37 Nakdong-Daero 550, Saha-gu, Busan 49315, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0893-0785","authenticated-orcid":false,"given":"Kunal Sandip","family":"Garud","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Dong-A University, 37 Nakdong-Daero 550, Saha-gu, Busan 49315, Korea"}]},{"given":"Seong-Guk","family":"Hwang","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Dong-A University, 37 Nakdong-Daero 550, Saha-gu, Busan 49315, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8857-4444","authenticated-orcid":false,"given":"Moo-Yeon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Dong-A University, 37 Nakdong-Daero 550, Saha-gu, Busan 49315, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"304","DOI":"10.1016\/j.enconman.2017.08.016","article-title":"Thermal issues about Li-ion batteries and recent progress in battery thermal management systems: A review","volume":"150","author":"Liu","year":"2017","journal-title":"Energy Convers.
