A new generation of energy storage systems based on Li-ion technology emerged at the end of the last century. To perform the first tests in safe conditions, Saft designed a simple electronic. Today, all Li-ion batteries for autonomous applications such as drones, launchers, missiles, torpedoes and 'human' applications such as cellular, laptop, hybrid vehicle and nearly sub-marines need a Battery Management System. The minimum in terms of functions is the overcharge and over-discharge protections. For a battery made of 2 cells connected in series or more, a balancing system is added to maintain the available energy during all the life of the battery. For stringent/demanding applications, the state of charge and state of health are calculated by one or more computers. It is now time to take benefit of the past 10 years of Saft's experience in the domain to re-evaluate the constraints of Li-ion batteries and provide customers with improved products by optimizing the battery management. Benefits of electronic for satellite applications: . Full control over battery. Confidence whatever the possible change of conditions in environment. The battery system can resist long exposure to gradient conditions with mitigated and stabilized impact on performances. The balancing function allow to use all the energy of all the cells: optimize of installed energy (compact design, mass saving). It started out with the basic fact that electrochemists are not intended to be space rated electronic experts and vice versa, even if Saft has a good heritage in the electronic battery management system. Consequently, considering heritage and expertise in their respective core businesses, Saft and ASP teamed up. It became necessary to provide an 'all in one' modular energy storage system with intelligent autonomous cell balancing management.
