Valeo to use TotalEnergies dielctric coolant to cool EV batteries

Date: 01/11/2022
In electric vehicles, batteries get heated up while charging and discharging. To extend the life of the battery, eliminating any discomfort to the passengers due to battery heat, and also to ensure the safety of the vehicle, there is a need to cool electric vehicle batteries. Most of the times air cooling is used to take the heat away from batteries. Companies are now trying to use liquid cooling.
TotalEnergies and Valeo have joined hands by signing agreement to develop a cooling technology to cool electric vehicle batteries using a very high-performance dielectric fluid.

TotalEnergies is offering its new dielectric coolant which can form direct contact with battery cells to pick the heat. Whereas Valeo is using its expertise in thermal systems management in effectively using this dielectric coolant in electric cars and other electric vehicles.

The joint research intend to decrease the weight of the thermal systems used to cool vehicle batteries. Lesser the weight of the systems used in electric vehicles, longer is the range car/vehicle can travel. Managing heat of batteries will also ensure avoiding fire risk. Valeo said it has developed comprehensive, smart, low-carbon thermal management systems adapted to charging intensity and speed.

“The dielectric fluid developed by TotalEnergies rounds out our TotalEnergies QUARTZ EV Fluid range aimed at electric mobility. It is a unique and innovative solution that aims to contribute to the decarbonization of the electric mobility sector – one of the company’s strategic priorities. What’s more, the technological advantage our product offers in terms of safety, one of our core values, makes it even more unique” commented Philippe Charleux, Senior Vice President, Lubricants & Specialties at TotalEnergies. “We are very pleased to be partnering with Valeo, with whom we share the same ambitions of accelerating the development of sustainable mobility solutions and achieving carbon neutrality.”

Francisco Moreno, President of Valeo’s Thermal Systems Business Group, commented: “Helping to reduce the impact of mobility is central to Valeo’s strategy. Technologies that contribute to reducing CO2 emissions now account for 60% of Group sales, and Valeo plans to continue expanding its portfolio of solutions that promote low-carbon mobility. This research partnership with TotalEnergies is an opportunity to create an innovative solution that will further accelerate consumer take-up of electric vehicles.”

With this program, Valeo to optimize electric powertrains in all areas where combining dielectric fluid with thermal systems can be beneficial.
