About us

Atomic and Alternative Energies Commission (CEA) is a French governmental research-and-technology organization with activities in energy, information technology, healthcare, defense and security. CEA-Tech, one of its divisions, focuses on creating value and innovation through technology transfer to its industrial partners. It employs 4500 scientists and engineers including 300 Ph.D. students and 300 assignees from partner companies. CEA-Tech owns more than 2200 patent families. It has a Large Research Infrastructure battery R&D platform that focuses on lithiumion battery development and small-run production, from materials synthesis through to integration. In parallel CEA develops a full multi-scale modelling platform for different e-components of electric vehicles (battery or hybrid with fuel cell) with a model based approach. Upscaling methodologies, in particular for lifetime models are included into the system level and control model. Predictive energy management strategies including durability constraints are developed for electric hybrid vehicle.

With more than 10 years of experience in new materials for Li-ions batteries and new battery pack architectures, the CEA work is completed by the researches carried out by the laboratory (Electronics, Energy and Power Laboratory), which develops innovative Battery Management Systems (BMS) and Fuel Cell Monitoring Systems (FCMS), as well as new application for safety increase in automotive and aeronautical applications.

Key assets for the project
The aeronautic sector is the main research field of CEA, but Smart Grid and electric arc prevention are also part of its research subjects. CEA is involved to select, define and optimize the energy storage system and relevant cell system. CEA is in close collaboration with several large industries involved in aeronautic activities. Main actions on these collaborations concern the battery cell selections, battery pack design, smart casing, optimization of the energy management, electronic design, thermal control management. All of these developments are managed considering the aeronautic standards and the safety.
