where the battery is cooled directly with a dielectric fluid, rather than indirectly via cooling plates. • As interest in immersion cooling grows, there is a desire for fluids that can be shared across the battery, motor, and power electronics. This requires coolants with low electrical conductivity, low viscosity, and good thermal properties.
A promising approach is battery immersion cooling, in which a dielectric fluid used as a coolant is in direct contact with the cells, the terminals and busbar. The dielectric fluid helps reduce the risk of thermal runaway, can mitigate its propagation, and improve the overall safety and performance of the battery system.
