EIGSI Project Manager: François Duclaud
Duration: November 2020 – …
Partners: CEA (French Alternative Energies and Atomic Energy Commission), IFPEN (French major research and training player in the fields of energy, transport and the environment), Gustave Eiffel University (IFSTARR Laboratory), CNRS (French National Centre for Scientific Research – IMS Bordeaux Laboratory), Bordeaux University, UTC (Compiègne University of Technology).
Objectives of the project:
COMUTES² is an original consortium with the purpose of organising and carrying out battery ageing campaigns.
The 6 consortium members are providing the test means and their expertise for successfully conducting each campaign. The precise theme of the campaign is chosen in agreement with the industrial stakeholders. Each test campaign is open to external partners. After registering to become a member, these partners are able to have a say in choosing and defining the tests. They also contribute funding for the latter.
The databases created out of the results of the test campaigns are owned in equal measure between the test institutes and the members. This information can be used for internal research purposes, as well as to provide data for PhD theses or research projects.
Why conduct accelerated battery ageing campaigns?
Accelerated battery ageing campaigns are carried out with three main objectives in mind:
- Understand the mechanisms behind a battery’s ageing
- Confirm the viability of new technologies
- Develop models for predicting a battery’s service life for a given application.
These ageing campaigns tend to be fairly long and expensive. This is due to the fact that they require considerable test resources as well as expertise for implementing experimental designs and interpreting the results.
The private partners
A number of public and private institutions are getting involved in these campaigns, including Valeo, DGA, Hutchinson and Siemens DIS.
More than a decade of research on the subject
Over more than ten years, IFPEN, CEA, EIGSI, Eiffel University, IMS and UTC have built up joint experience in the roll-out and interpretation of accelerated battery ageing campaigns. Over this time they have taken part in various collaborative projects including PREDIT SIMSTOCK (2007-2010), ANR SIMCAL (2010- 2013) and FUI MOBICUS (2014-2017). Today, these six partners are harnessing this experience for the benefit of others by sharing it through the COMUTES² consortium.
