properties. In smaller-sized EVs, such as Nissan LEAF and Wuling Mini EV as well as some Japanese EV models, the air cool- ing method still prevails, as this method offers cooling that is good enough to keep small-sized batteries of these cars under optimal temperature range. The third technology is immersion cooling, where the EV battery unit is completely immersed in a dielectric cool- ing fluid, with electrical conductivity well below 10 micro siemens. This new tech- nology is currently in the R&D phase and undergoing trials and has not yet been applied at scale by passenger car OEMs. However, the trend toward immersion cooling seems strongly driven by the de- velopments in electric and fuel-cell ve- hicles. A compelling example of this is a July 2022 trial by TotalEnergies, in which the company incorporated an immer- sion-cooled battery in a road-going pas- senger car, a Volvo plug-in hybrid car. It is also evident that in current times,


nobody has a monopoly on innovation when it comes to immersion cooling technology. Several new players have entered this market to offer immersion cooling solutions for EVs. One prominent example of this is Xing Mobility, which is a Taiwan-based developer of immersion cooling battery packs. The company is an integrated solutions provider for EV batteries and offers modular battery pack systems based on immersion

nered with Castrol to further develop its Immersion Modular Battery Pack tech- nology solutions which will be targeted toward EV applications. To sum it all up, in an era where mobil-


ity is defined by the quest for lower en- vironmental impact, the changes in cool- ant technology have become the need of the hour. Environment protection norms are becoming increasingly stringent and are driving changes in vehicle designs, such as reducing the weight of the vehi- cles, smaller and higher power engines, changing vehicle metallurgical composi- tion, increasing the number of electronic components, and growing penetration of electric vehicles. These changes in au- tomotive design are exerting increased performance pressure on the vehicle’s

systems take the center stage as an en- abler for increasing efficiency in auto- motives, cooling fluids are expected to experience significant changes. The cool- ant industry is currently seeing develop- ments in existing in-direct product tech- nology which is targeted toward internal combustion engine (ICE) vehicles as well as current EVs, although it seems like a short-term solution for EVs. At the same time, the coolant industry is on the brink of a technological breakthrough for im- mersion cooling driven by strong trends toward electric and fuel-cell vehicle de- velopment. Keeping this in view, the next five to 10 years are anticipated to see landmark changes in coolant fluid tech- nology transition and would certainly be an interesting market to observe. The findings for this article have been


drawn from Kline’s recently completed study on automotive coolants. The study covers, in detail, trends in this market and evaluates the demand for cooling fluids by ICE and electric vehicles in 10 country markets including Brazil, China, France, Germany, India, Japan, Mexico, South Africa, the United Kingdom, and the United States.
