Castrol ON EV Thermal Fluids
Castrol ON EV Thermal Fluids are designed to keep electric trucks batteries cooler, enhancing performance and extending their lifespan.
Charge faster and last longer*
Electric trucks and heavy duty vehicles can run hot under heavy loads and long operating periods.
Castrol ON EV Thermal Fluids are formulated to keep E-trucks batteries cooler, even in extreme conditions, reducing maximum temperatures during ultrafast charging.
This enables ultra-fast charging and helps extend battery life, improving efficiency in the vehicle.

Why choose Castrol ON EV Thermal Fluids for electric trucks?
The challenge
Effective thermal management is crucial to ensure the safe and efficient operation of heavy-duty EVs in all conditions, including the prevention of thermal runaway. It also supports efficient recuperation, helping to maximise energy recovery and extend vehicle range from every charge.
Without proper cooling, batteries may require extended cooldown periods after long hauls, leading to downtime and delays before fast charging can resume. Looking ahead to megawatt fast charging, direct cooling fluids must be capable of preventing battery derating under extreme heat loads.
The difference between direct and indirect cooling
Indirect cooling
Indirect cooling transfers battery heat through an intermediate component, helping to keep cells within safe operating ranges. Castrol Radicool's advanced indirect thermal fluids are engineered to provide reliable performance, efficiency, and protection for a wide range of EV designs.
Direct cooling
Direct cooling immerses battery cells directly in a dielectric fluid, offering superior thermal performance and enabling faster charging. This approach ensures consistent temperature control, improved safety, and extended battery life. Castrol ON EV Fluids are driving the next generation of EV performance.
Castrol delivers solutions for both indirect and direct cooling systems – helping manufacturers push the boundaries of performance, safety, and sustainability.
The solution
Compared to traditional dielectric fluids – such as transformer fluids – Castrol’s thermal technology enables superior heat transfer, extending battery life to help reduce total cost of ownership (TCO).
Key characteristics include:
- Electrical insulation resilience and a high flash point for protection against degradation and ignition.
- Formulated to be compatible with a wide range of materials – ensuring system integrity and long-term reliability, for reduced TCO.
- Lower viscosity and flow resistance help to reduce pumping power requirements and improve overall system efficiency.
Castrol ON EV Thermal Fluid
The battery is the most valuable component in heavy-duty vehicles. Direct cooling with Castrol ON EV Thermal Fluid helps extend battery life by keeping batteries cooler – even in extreme conditions – minimising thermal degradation over time. Its superior properties enable improved battery thermal management performance.
Charge faster and last longer*: Castrol ON EV Thermal Fluids can help reduce the maximum temperatures which the cells reach during ultra-fast charging.
