New Energy Battery Cooling Fluid

New fluids coming for EV thermal management

This method uses an oil-based ''dielectric'' fluid, with very low or zero conductivity, depending on the formula. The fluid flows directly over the motor coils. Dielectric fluids are also entering battery thermal management; with direct (also known as immersion) cooling, the battery cells are submerged in the dielectric coolant.
