L3E is a laboratory specialising in electrical energy storage. Accelerated life testing of batteries (charge and discharge cycles) is performed to understand the ageing mechanisms and confirm the viability of new technologies. It also enables the development of models for predicting a battery’s service life.
These tests are also used to determine the optimum configuration of BMS (Battery Management System) control algorithms. The laboratory has recently undertaken research on fuel cells both in terms of the characterisation part (operating tests on the whole system) and the management of EMS (Electronic Management System) control algorithms.

Explanation of the project:
COMUTES 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 which is chosen in agreement with the industrial contractors.
These tests are aimed at understanding the mechanisms behind battery ageing, confirming the viability of new technologies and developing models for predicting a battery’s service life for a given application.
Duration: September 2013 – February 2017
MAT4BAT is a project for assessing and optimising battery service life. It enables certain components that are more effective than others in the composition of battery cells to be singled out. It also paves the way for charge/discharge protocols with a view to optimising battery service life.
EIGSI’s expertise and contribution regarding this programme involve the preparation of the measuring protocol based on the results obtained.
Duration: September 2013 – August 2016
The MOBICUS project aims to develop and confirm the viability of strategies for prolonging battery life depending on vehicle use and charging modes, based on experimental measurements and validations.
