The Institute for Energy Transition INES.2S is developing methodologies and tools for optimal management of stationary storage systems. Based on the results of tests on several battery technologies (nearly 500 references), our laboratories are developing, among other things, advanced technologies to evaluate battery status indicators (charge, health, etc.) in order to optimize their management and improve performance and life time.
Lithium ion batteries currently offer the highest energy density. This makes them the technology of choice for powering many applications (electric vehicles, electricity storage for networks, etc.). However, these batteries are subject to performance degradation - particularly in terms of capacity and resistance - over time, even during periods of non-operation. The performance of batteries can be determined using indicators such as SOH (State Of Health).
Among approaches currently developed, the scientific and industrial community is seeking to develop the best management strategies, taking into account the degradation of the battery's life that it induces.
