In the laboratory, we perform various types of tests, such as electrical and thermal characterization, aging of cells and complete storage systems, and abuse tests on cells and small modules.

Our activities aim to achieve several research objectives: 

• Experimental characterization of innovative storage systems through varying work profiles and controlled environmental conditions. The results help us compare different technologies and evaluate potential applications, as well as define optimized management modes for each technology tested. 
• Electrochemical characterization and impedance spectroscopy of storage systems to develop electrical models and charge state and energy estimators. 
• Development of aging models to measure the useful life of storage systems under various operating conditions, with the goal of optimal sizing during design.
• We also focus on online prediction of the remaining useful life of the system to minimize the cost per lifecycle. 
• Development and testing of tools for fault diagnostics and prediction. 
• Experimenting with solutions to optimize the management and maximize the performance of storage systems. For example, we are developing prototypes of active Battery Management Systems that can manage cells of different power levels, including for second-life applications.
