Valeo and TotalEnergies have expanded their partnership at this year's Paris Motor Show, focusing on the enhancement of electric vehicle (EV) battery performance.

This collaboration aims to develop a new cooling solution for EV batteries and create a single fluid to improve thermal management across the vehicle.

Since the partnership's inception in 2022, the two companies have been working on a cooling system that utilises liquid dielectric technology.

Valeo Power Division chief technology officer Christophe Delhovren said: “Since the beginning of our partnership in 2022, the collaboration between Valeo and TotalEnergies has led to faster development of innovative, safe and effective solutions for the thermal management of batteries.

“We have reached the stage to extend our partnership, which no longer concerns the battery alone, but all parts of the powertrain, in order to maximise thermal optimisation.”

“This collaboration is central to Valeo’s strategy for innovations that meet the challenges of affordable, reliable, low-carbon EVs.”

The system is designed to maintain an optimal battery temperature, which can enhance battery autonomy, reduce carbon footprints, and minimise fire risks. Field trials are currently assessing the system's effectiveness, especially during rapid charging.

The second initiative of this collaboration is to extend the benefits of the new immersive fluids to other vehicle components. The objective is to develop a thermal management system that can improve energy efficiency and extend the range of future EVs.

TotalEnergies chief technology officer Marie-No?lle Semeria said: “The partnership between TotalEnergies and Valeo will bring innovations to the thermal management of batteries and EVs by using immersive fluids that enable very rapid charging while preserving battery life.

“These innovations contribute not just in EV performance, but also in carbon footprint reduction, for even cleaner transport.”

In July, Valeo has also entered a strategic collaboration with Seeing Machines to design AI-powered operator monitoring systems to improve transport safety.

In the same month, TotalEnergies also signed a binding agreement with UK power firm SSE to create a joint venture under the brand 'Source'.

This venture aims to become a significant player in EV charging infrastructure in the UK and Ireland, with plans to deploy up to 3,000 high power charge points across both countries within the next five years.
