In the heart of every modern battery electric vehicle lies a meticulously arranged network of small battery cells.
These “battery packs” are the key power sources for plug-in hybrid or full electric vehicles. Unfortunately, they’re also prone to excessive heat issues, such as battery thermal runaway, that can compromise battery lifespan.
Battery thermal runaway refers to a critical safety condition that can occur in EV batteries, where a self-perpetuating, uncontrollable increase in temperature and energy release leads to catastrophic failure, including fires or explosions.
Immersion cooling effectively suppresses and stops battery thermal runaway. It can also offer benefits such as enhanced cooling, quicker charging, and improved battery performance.
But to fully maximize these advantages, battery thermal management fluid solutions must cater to both the specific needs of the application and the electrically charged environment.
