After four years of intense projects and severe simulations, a team of 25 specialists who include engineers and researchers of Cnrs, the French National Centre of Scientific Research, has revealed a battery system known as Ibis (Integrated System of Intelligent Batteries). Ibis is supported by the Future Investment Plan, managed by Ademe (the French agency for the environment and the energy management) and coordinated by Stellantis. The primary participants in the project include Saft (TotalEnergies Group), E2CAD and Sherpa Engineering, together with the research laboratories of Cnrs and Institut Lafayette.
The specificity of this innovation resides in its design: the battery combines an inverter and a charger, notably increasing the efficiency and the longevity of batteries for electric vehicles. Moreover, this new configuration decreases costs and at the same time frees inner space in the vehicle.
Ibis is not only a product, but a real project that started in summer 2022, a system that changes the way according to which conversion boards are positioned as close as possible to the elements of the lithium-ion battery: a strategic position that allows the battery to produce directly alternate current for the electric motor.
Ibis has the potential to reduce the weight and the manufacturing costs of electric vehicles and to widen the range of available functions. From the point of view of the stationary energy, Saft provides for offering turnkey plants that enable a more efficient energy use, decreasing the environmental impact. Ibis battery by Stellantis also offers a simplified maintenance and an enhancement of plants.
