Stellantis and French Alternative Energies and Atomic Energy Commission (CEA) teams have presented the first advances of their collaboration in the field of digital modeling of batteries meant for EVs and hybrid vehicles. They are sharing research work under a five-year framework contract partnership that aims to identify emerging long-term automotive technologies.

The automaker says that the contract with CEA is strategic for activities related to electric, connected, and autonomous vehicles, as well as the factories of the future and services. Projects already underway concern the detailed modeling of current battery technologies, it adds.

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 next five years to come.

"We are happy to benefit from the expertise of the CEA", said Nicolas Champetier, Senior Vice President of Advanced Engineering Propulsion Systems, Stellantis. "This work on digital modeling 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', 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 the group to become the industry champion in the fight against climate change, in particular, state-of-the-art battery technologies.

Stephane Siebert, Director of Technological Research, CEA, noted, "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".

The CEA's mission is to promote the technologies it develops to support the competitiveness of companies and national technological sovereignty. At the same time, the search for economic and environmental optima of the energy transition requires the design of components integrating the imperatives of sobriety, durability, and recyclability.

It is a key player in research, development, and innovation in four main areas, namely, energy transition, digital transition, technology for the medicine of the future, and defense and security. As the only French public research institute listed among the Top 100 Global Innovators (Derwent 2020), the CEA acts as a catalyst and driving force for innovation to boost the French industries.
