摘要

电动汽车的电池需要适当的冷却，以提高诸如高能量密度和快速充电能力等性能。将电池浸泡在介电流体中，在安全性和性能方面有很大的好处，但选择相关的冷却剂仍然是一项复杂的任务，而且汽车电气化领域的工程师缺乏指导。本文回顾了对该应用最重要的流体特性，并提供了一种候选流体在各种老化条件下的关键特性的实验比较，这些条件是为了在车辆中重现数年的运行。

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 of the cells in a dielectric fluid provides substantial benefits in terms of safety and performance, but the selection of a relevant coolant remains a complex task and guidance to engineers in the field of vehicle electrification is sparce. This paper reviews the fluid properties which are considered most significant for this application, and provides an experimental comparison of the key properties of one candidate fluid under various aging conditions devised to reproduce several years of operation in a vehicle.
