Prestone's Groundbreaking EV Thermal Management Solutions

Prestone, a global leader in automotive fluids under the Performance Fluid Experts (PFX) Group, is set to unveil its latest innovations in electric vehicle thermal management at the 2025 Battery Show North America in Detroit, scheduled for October 6-9. The company aims to address the growing demands of electrified vehicles (EVs) with its Prestone EVX™ range of fluids, designed to enhance performance while ensuring safety.

Addressing Industry Needs

As the electric vehicle market continues to expand, manufacturers are increasingly faced with stringent performance standards and safety regulations. Prestone's EVX™ fluids are engineered specifically to meet these emerging needs, offering low electrical conductivity, excellent corrosion protection, and superior chemical stability for both light- and heavy-duty EVs. These formulations are a response to the new industry standards set to be implemented in various markets, with a significant effect seen in China starting October 2025.

New Regulations and Standards

The EV cooling fluid market is evolving rapidly, with new regulations such as the GB29743.2 standard implemented in China. This standard aims to enhance the electrical safety of EVs by reducing the conductivity of cooling fluids. Prestone's EVX™ collection exceeds these requirements, aligning with the ASTM D8566 standard focused on minimized electrical conductivity to ensure the safety of EV batteries.

Tom Corrigan, the Director of EV and Electrification Technology at Prestone, stated, "Our technologies are designed not only to meet today's EV demands but to anticipate tomorrow's." This approach positions Prestone as a crucial player in the evolving EV supply chain, enabling automakers to stay ahead of regulatory changes while maintaining performance.

Diverse Eco-Friendly Solutions

Prestone’s EVX™ product line includes:

• - Phosphate-based Organic Inhibitor Technology: A low-conductivity coolant that protects against corrosion without the use of silicate, borate, or amine.
• - Silicate-based Organic Inhibitor Technology: This offers enhanced reserve alkalinity for improved performance and corrosion protection.
• - Non-Ionic Inhibitor Technology: Developed for fuel cell vehicles, this coolant is custom-engineered for reliability, ensuring compatibility with next-generation mobility standards.

Ensuring Safety Through Rigorous Testing

Managing high-voltage operations in electric vehicles is critical, particularly given that EVs operate at voltages ranging from 400 to 1000 volts. To validate the safety and efficacy of its EVX™ fluids, Prestone partnered with Exoes, a leading firm in electromobility thermal management testing. They have developed a unique test that simulates real-world high-voltage conditions, showcasing how Prestone’s EVX™ fluids can maintain low current levels to prevent combustion and thermal runaway, a significant risk in electric propulsion systems.

Commitment to the Future of Electrification

Prestone is committed to supporting the global transition towards electric mobility. The company currently invests more than three million gallons of its EV thermal management fluids annually to automotive manufacturers, utilizing its robust tech solutions from product creation to manufacturing and warranty support. The PFX Group, which encompasses various brands, produces over one billion liters of industrial and mobility fluids each year across more than 100 countries.

In addition to automotive applications, Prestone is expanding its support for electrification into other sectors such as mining, construction, and agriculture with its heavy-duty Prestone Command EVX™ fluids.

Conclusion

Attendees of the Battery Show are invited to visit Prestone’s booth (#3238) to explore the revolutionary thermal management solutions tailored to optimize vehicle safety and performance across a wide spectrum of electric vehicle types and conditions. Prestone continues to lead the charge in the EV market, aligning its innovations with future demands to create safer and more efficient electrified transportation solutions.
