CLEFS CEA N°65 - LES VOIX DE LA RECHERCHE - ENERGY TRANSITION
Electricity storage is essential to the correct working of the grid as it progressively integrates higher rate of intermittent energy sources. Various technologies are today being studied for short and medium-term applications: electrochemical, chemical (hydrogen) and thermal storage solutions.

Management System (or BMS). The BMS is a complete system comprising measurement and balancing functions, battery status and safety algorithm and also active control. Research is focusing on management algorithms and on the power electronics. The BMS can also contribute to improving the safety of the packs, as the batteries entail a risk of thermal runaway. With (real or virtual) sensors capable of detecting temperature rises or early warning signs of runaway (internal short-circuit by dendrite growth) at an early stage, it is then possible to trigger protection actuators, for example by bypassing the defective cell or by activating a cooling system.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
