Hybrid and electric powertrains
CARA European Cluster for Mobility Solutions
IFPEN is one of the founding members of CARA, the Auvergne-Rhône-Alpes region competitiveness cluster, set up to support changes in urban transport systems and represent the local car and industrial vehicle sector.
« IFPEN is a long-standing partner of CARA and has always played a full role in its governance and activities. Its representative is vice-chair of the Innovation activity - one of the support components we offer our members - and leads our “Powertrain and drive train” research program. We can also depend on IFPEN’s expertise covering themes such as batteries and IC engines, etc. when we are setting up collaborative projects involving our members. Through this active participation, IFPEN brings not only its know-how in numerous fields (mechanics, chemistry, software, data analysis, etc.), but also access to its Solaize site, where we regularly host think tanks and international delegations.
I would say that we have built up a relationship of trust and proximity, based on the proactive pooling of our expertise. We would like to strengthen this partnership further in the future, particularly through participation in European projects. »

Mov’eo: for more environmentally-friendly transport
IFPEN is one of the founding members of the Mov’eo competitiveness cluster, which leads an industrial and scientific ecosystem dedicated to issues surrounding the mobility of the future. It is also one of its most active members.
« IFPEN has played a major role in Mov’eo since its creation in 2006, particularly through the presence of its experts in our communities: “Powertrain and energy management”, “Energy storage”, “Smart mobility solutions”, etc. The role of these communities is essential, since they define the strategic vision of each theme, foster the emergence of projects and support those leading them. IFPEN is very present in this field, participating in 42 projects labeled by Mov’eo. Initially focusing on the powertrain, today’s projects have shifted more towards batteries and energy management, themes in which IFPEN’s expertise is widely recognized. Lastly, IFPEN plays a role in our governance as a member of the board of directors, thereby contributing to the evolution of our innovation strategies. For our part, we work closely with some of the start-ups in IFPEN's portfolio such as DriveQuant, and support CARNAUTO, a consortium of 9 Carnot institutes led by IFPEN dedicated to intermediate-sized companies, SMEs and micro-companies in the vehicle and mobility sector. »

H2020 Demobase Project
To support the development of electric mobility, the European Demobase project is pursuing several objectives:
- to reduce development efforts for electric powertrains,
- to improve their efficiency by 20%,
- to optimize their safety.
Led by project coordinator SAFT, the French battery manufacturer, the 11 partners are working on the global optimization of the development process, the ultimate aim being to create an all-electric London taxi-type demonstrator.
« Our expertise in the field of system simulation, drawing on the libraries of the Simcenter Amesim™ platform, is being harnessed in the early phases of the project to speed up research progress. In particular, development processes using Hardware-in-the Loop approaches on our battery test benches will be evaluated. We are also contributing to research relating to battery safety, building on a joint thesis on the subject with Ineris, also a project partner. Our objective is to develop thermal runaway models for various latest-generation Li-ion battery cells produced by SAFT, and evaluate the benefit of these models in the battery pack pre-design phases, taking safety into account. The research will then be validated by tests conducted on prototypes at Ineris. »

H2020 ReFreeDrive Project
« The use of rare earths remains a major constraint in terms of the cost of synchronous reluctance electric machines: within the context of the H2020 ReFreeDrive European project, we are working with 12 partners on a concept for a synchronous reluctance machine capable of operating without rare earths. We are responsible for the design of the electric machine, as well as the control strategy and the integrated inverter, for two electric powertrain applications with a target power of 200 and 75 kW. For the purposes of the project, we are also providing a testing resource to test the different prototypes. »

H2020 ADVICE project
Launched in 2017, the European ADVICE (ADvancing user acceptance of general purpose hybridized Vehicles by Improved Cost and Efficiency) project is aimed at fostering the widespread use of hybrid technology in the vehicle market, particularly in the premium vehicle segment. IFPEN is one of the partners.
« One of the obstacles hampering the widespread use of hybridization is vehicle energy efficiency, a field in which our control and command expertise is invaluable. Within the context of the ADVICE project, we developed an eco-routing solution making it possible to find the most energy-efficient route as a function of real-time traffic conditions. The original feature of this solution is that it is predictive, i.e., it uses the vehicle’s connectivity to predict and improve energy efficiency. Tests are due to take place in 2019.
We also designed a simulation platform connected to a cloud to test control algorithms. Having supplied these two deliverables, we continue to play an active role in their implementation and validation on three demonstrators developed for the project. »
Spurred on by IFPEN teams, the Consortium for the Pooling of Electric Tests on Storage Systems (COnsortium pour la Mutualisation de Tests Electriques sur Systèmes de Stockage, or COMUTES²), bringing together six experimental laboratories working on batteries (IFPEN, CEA, Gustave Eiffel University, IMS, UTC and EIGSI), was created at the end of 2018. Their objective: to bring together a group of researchers to set up battery test campaigns open to outside members, interested in their results and prepared to contribute to their funding.
« The study of battery aging, particularly in order to calibrate behavioral models, requires access to a large volume of test data covering different temperature and stress conditions. Generating these data requires the long-term mobilization of numerous testing resources. By pooling these resources and sharing costs, the consortium’s members are capable of addressing these challenges quickly and efficiently.
The original aspect of COMUTES² also lies in its innovative format, the brainchild of the 6 founding partners boasting more than 10 years’ shared experience with the Simstock (ADEME), Simcal (ANR) and Mobicus (FUI) projects. We are collectively inventing a new approach to working together, hinged around the joint ownership of test results between researchers and members. In September 2020, the COMUTES² consortium started its first campaign devoted to the cold cycling ageing of Li-ion batteries. Five members (VALEO, EDF, Directorate General of Armaments (DGA), Hutchinson and Siemens) were on hand to take part in the study.»
The electrochemical energy storage network (RS2E) brings together public and private players to work on problems related to different energy storage solutions, for stationary or vehicle applications.
« Through our participation in the RS2E network, we are able to consolidate our research in the field of batteries, particularly by:
- linking our developments to industrial needs,
- identifying research partners,
- setting up collaborative projects.
It was in the context of the RS2E network that we conducted joint PhD research with Ineris on thermal runaway for new and old Li-ion batteries. The resulting thesis attracted the interest of industrial players, who asked us to join the H2020 Demobase project. »

IFPEN is working in partnership with start-up company Doctibike on electric bicycle battery recycling within the framework of the Energyk project , financed by the Auvergne-Rhône-Alpes region. The aim of Energyk is to develop battery packs for electric bicycles that can be recycled, reused and repaired.
