Aging of a dielectric fluid used for direct contact immersion cooling of batteries

Batteries of electric vehicles require appropriate cooling to allow for increased performances such as high energy density and fast charging capabilities. Immersion the cells in a dielectric fluid provides substantial benefits terms safety performance, but selection relevant coolant remains complex task guidance engineers field vehicle electrification is sparce. This paper reviews properties which are considered most significant this application, an experimental comparison key one candidate under various aging conditions devised reproduce several years operation vehicle.
