Stellantis and the CEA collaborate on EV battery modeling

Stellantis and the French Alternative Energies and Atomic Energy Commission (CEA) have presented the first advances of their collaboration in the field of digital modeling of batteries.

These models, which make it possible to analyze charging time strategies and the mechanisms of battery degradation, are intended to increase their lifespan for customers, and to better control the environmental impacts of the various battery technologies in the five years to come.

Stellantis says the contract is strategic and ambitious for activities related to electric, connected and autonomous vehicles, as well as the factories of the future and services.

The two groups have been sharing research work under a 5-year framework contract, and the overall aim of the project is to identify emerging long-term automotive technologies. Stellantis has confirmed that projects are already underway concerning the detailed modeling of current battery technologies.

“We are happy to benefit from the expertise of the CEA”, said Nicolas Champetier, Senior Vice President Advanced Engineering Propulsion Systems, Stellantis. “This work on digital modelling will have a positive impact on the performance and cost of use of batteries for customers.”

As presented in its strategic plan Dare Forward 2030 on March 1, 2022, Stellantis aims to build on cutting-edge ideas to offer its customers innovative, clean, safe, and affordable mobility solutions. In its electrification strategy, technological partnerships with key companies have a key role in enabling Stellantis to become the industry champion in the fight against climate change. In particular, thanks to state-of-the-art battery technologies in terms of energy efficiency and cost-in-use for customers.

“The CEA is proud to provide Stellantis with its technological expertise, considering all stages of the product life cycle, from its design to its end of life”, said Stephane Siebert, Director of Technological Research, CEA.
