CEA is the Atomic and Alternative Energy Council, a research state agency employing a staff of 16,000 people. The Research and Technologies Division (DRT) is one of the four operating divisions, whose policy is to meet the needs of partners both in the CEA and in the industry. 

Within DRT, LITEN (Laboratory for Innovation in New Energy Technologies and Nanomaterials) is a CEA institute, mostly located in Grenoble. CEA-LITEN is the leading centre for new energy technologies in France, with close to 1,100 people and more than 1,000 patents. CEA-LITEN has a very strong expertise and background in the field of Li-Ion batteries, Battery Management Systems, electric driveline and drivetrain, and has been working for more than fifteen years in these sectors and participated in many European and French projects with strong industrial relationships. CEA has a long time experience in designing, prototyping, manufacturing and testing of electric storage solutions and related drivelines. CEA is involved in a long term partnership with Renault in developing next generation electric driveline solution. More specifically, LITEN is equipped with a full Li-ion assembly line, a battery pack, battery management system and driveline control assembly line. 

The research group involved in the ESPRIT Project that is part of the LITEN/DEHT (Department for Electricity and Hydrogen in Transportation) is called the SIGE (Service for Integration of Electrochemical Generators). The following laboratories will especially contribute to ESPRIT: the LAE (Laboratory for electrical Architecture), the L2EP (Laboratory for advanced Electronics, Energy and Power), the LAMF (Laboratory for Mechanical and Fluid Architecture) as well as the L2M (Laboratory for Modelisation and Monitoring). Finally, the SRGE (Service for
Realisation of Electrochemical Generators) will also be involved through the LRGE (Laboratory for the Realisation,of Electrochemical  enerators).
CEA LIST Within DRT, LIST (Laboratory of applied research on software-intensive technologies) is a CEA institute, mostly located in Saclay, France. CEA LIST is a leading centre for software-intensive technologies in France, with close to 700 people and 300 patents. CEA LIST leads R&D activities focused on software-intensive systems with strong economic and societal stakes, including embedded systems, interactive systems, robotics, sensors and signal processing. By developing cutting-edge technological research in partnership with major industrial players in the nuclear, automotive, aerospace, defence and medical sectors, CEA LIST enhances the industrial competitiveness of its partners by developing innovative solutions appropriate to their needs, going from concept to system demonstrator, and contributing to technology transfer and innovation through the emergence of new businesses. 

Two CEA LIST research groups will be involved in the project :

The Interactive Robotics Laboratory (LRI), focused on robotics and human/machine interaction, and leading R&D activities centred on  echatronics, control and supervision of robotics systems. The LRI has a strong background in robotics embedded control system design and integration, through the development of several robotics systems transferred to industrial companies and currently in operational use. The interactive robotic unit aims to develop the systems and control algorithms for the robots interacting with humans. Historically oriented nuclear, and more precisely force feedback teleoperation, diversification scopes allowed to perpetuate and to provide these technologies in various sectors, such as security, medical or production. 

The Embedded Real-Time System Foundations Laboratory (LaSTRE) is specialised in building compilers and runtime environments for safety, security or performance-wise critical systems. A number of technologies developed in the laboratory have been transferred to private  ompanies and are now commercially exploited. As a recent example, the lab has developed a complete dataflow compiler and RTE for the 256-cores MPPA architecture commercialised by KALRAY Inc. which is now commercialising the aforementioned compiler as part of its AccessCore SDK (achieved best HEVC implementation at the CES 2014). Since 2010, the team develops its activities in the fields of mixed-criticality, safe and secure virtualisation and cryptographic runtime environments (hardware-assisted or not). Mixed-criticality research topic addresses design of a framework and runtime to develop systems with real-time constraints, high-performance needs and safety  equirements.

Role in the project

CEA will lead the project as coordinator from both strategic and scientific and technical points of view. In terms of technical work, CEA LIST will participate in developing the control strategies that enable to drive the vehicles in an individual way or in a road train configuration. This control law will allow to accelerate, brake the vehicles or the road train, in forward or in gear, while preventing the lateral oscillations or the jack-knifing of the road-train. CEA LITEN will lead and participate in developing the energy storage solutions to enable the charging of a road train using a single charging station, and the balancing of the batteries of the various vehicles of the road-train when towed together.
