TotalEnergies, Valeo partner to innovate EV battery cooling

VALEO GROUP | 20 OCT, 2022: TotalEnergies and Valeo announce that they have signed an agreement to develop an innovative way of cooling electric vehicle batteries using a new, very high-performance dielectric¹ fluid.

Not only would this innovation improve the way electric vehicles are used, but it would also reduce their carbon footprint.

With current technology, fluids cannot be used to cool the battery from within. But TotalEnergies has developed a new, innovative dielectric coolant that can be in direct contact with battery cells.

Valeo will contribute its expertise in the related thermal systems to design and build the best solution to integrate the coolant within the electric vehicle battery pack, thereby optimizing performance by conditioning it at the right temperature.

Research conducted under the agreement will enable Valeo to reduce the weight of the thermal systems used to cool vehicle batteries – greatly improving the overall weight, travel range and carbon footprint of electric vehicles – and improve safety in response to battery fire risk.
