Zusammenfassung

Lithium-Ion Batteries have undoubtedly become the Holy Grail of the EV industry. Increasing battery lifetime, energy density, and safety are central are key technical issues for the Automotive Industry. This paper presents a battery thermal management system, helping in increasing battery lifetime, but, above all, making the battery pack safer. This system relies on the use of an innovative dielectric fluid in direct contact with electrochemical cells. The key innovation relies on the fluid behavior when exposed to extreme heat generated during a battery thermal runaway event. Its specific chemical structure allows to avoid propagation, even in a severe scenario where common fluids are getting ignite and catch on fire. Experimental results will be presented to demonstrate the performance and the versatility of this solution.
