Design and development of battery thermal management using immersion cooling.

Lithium-ion batteries has promising future in electric vehicles and storage of electricity. The two main issues with these batteries are the charging time and the heating problems. When we vary the discharging and charging rate of the battery, the temperature also increases/decreases respectively. Battery thermal management has a crucial role of maintaining life-cycle and performance of.battery. A battery thermal management system ensures thermal repeatability and prevents thermal runaway of battery. The paper presents the results derived from the experimentation undertaken with this purpose. An experiment was performed on Lithium-ion 18650 battery cells, which are charged with 2 C charging rate which are cooled with immersion cooling via dielectric fluid. The use of this BTMS ensures the thermal runaway is minimized and all the cells are cooled uniformly, which make sure that all the cells are working under desirable conditions. The simulation was verified with experimentally. [ABSTRACT FROM AUTHOR]
