Immersion liquid cooling addresses this challenge by placing battery cells or modules in direct contact with an electrically non-conductive cooling fluid. The fluid absorbs heat from the battery surfaces and transfers it to a heat exchanger or external cooling circuit. Compared with conventional air cooling and indirect cold-plate systems, immersion cooling can provide more uniform contact with battery components and reduce thermal resistance. This may support higher charging rates, improved temperature consistency and longer battery operating life. The market is creating opportunities for battery manufacturers, electric vehicle companies, thermal-management suppliers, dielectric-fluid developers, energy-storage integrators and engineering businesses.

What Is an Immersion Liquid-Cooled Battery System?

An immersion liquid-cooled battery system is a thermal-management solution in which battery cells, modules or selected electrical components are submerged in a dielectric cooling fluid.

The cooling medium must be electrically insulating so that it can directly contact energized battery components without creating a short circuit.

A typical immersion cooling system may include:

Battery cells or modules
Dielectric cooling fluid
Sealed cooling enclosure
Fluid pumps
Heat exchangers
Sensors and controllers
Expansion tanks
Filtration systems
Pressure-management components
