Battery immersion cooling is finding applications in high end luxury sports cars. The new McLaren “Ultimate Series” named as “Speedtail” is the first serial car worldwide to implement immersive battery technology.
Safety implications of battery immersion cooling discussed. Research gaps in battery immersion cooling presented. Battery thermal management systems are critical for high performance electric vehicles, where the ability to remove heat and homogenise temperature distributions in single cells and packs are key considerations.
To address this challenge, immersion cooling technology, which has high thermal transport efficiency, good temperature uniformity, and low energy consumption, is gradually becoming a new research field for lithium-ion battery thermal management.
In conclusion, compared to traditional air cooling and liquid-cooled plate technologies, immersion cooling effectively extends battery life and decreases the lifecycle fee of batteries.
At the simplest level, immersion cooling is exactly what it sounds like: a system that contains liquid with a battery pack immersed in it. No cooling jacket is needed and the dielectric fluid comes into direct contact with the battery. This enables faster cooling and safer operation. Following are some of the advantages of immersion cooling:
Performance of battery immersion cooling and different cooling fluids reviewed. Immersion fluids can increase heat transfer by up to 10,000 times compared to air. Thermal properties of lithium-ion batteries and heat transfer mechanisms explored. Safety implications of battery immersion cooling discussed.
