Castrol ON EV Thermal Fluids

The challenge

Next-generation battery electric vehicles are moving to direct cooling for battery thermal management, in order to enable fast charging and better performance. Efficient direct cooling requires advanced dielectric thermal management fluid technology to maintain battery performance over the lifetime of the vehicle.

Castrol's thermal technology 

Castrol ON EV Thermal Fluids with advanced properties have been developed to enable improved battery thermal management in electric vehicles. It has superior properties to enable improved battery thermal management performance:​

• Lower viscosity than conventional dielectric fluids such as transformer fluids that enable efficient heat transfer​.
• Strong electrical insulation and high flash point to protect against breakdown and ignition​.
• Oxidation resistance to maintain performance over the fluid's lifetime.​

Castrol ON: EV Thermal Fluid

Our EV Thermal Fluid keeps electric vehicle’s batteries cooler, even in extreme conditions. Its superior properties enable improved battery thermal management performance.

Charge faster^2*:  Castrol ON EV Thermal Fluids can help reduce the maximum temperatures which the cells reach during ultra-fast charging.
