New intelligent lithium battery integrated inverter

Integrating the inverter and charger functions creates a battery that is more efficient, which enhances the battery electric vehicle range and is more reliable and less costly. It also frees up room in the vehicle. The collaborative research project is known as the Intelligent Battery Integrated System (IBIS).

Saclay, France - After four years of design, modeling and simulation, a team of 25 people comprised of CNRS (French National Center for Scientific Research), Stellantis and Saft engineers and researchers today unveiled an innovative prototype of an energy storage battery that integrates the inverter and charger functions.

The new design integrates charger and inverter functions into the battery, making the powertrain more efficient, more reliable, and less costly. The design still works with lithium-ion cell chemistry, but integrates more functions into the battery itself.

The new technology integrates the inverter and charger within the battery to save space. Stellantis has revealed a prototype electric vehicle battery, which integrates the inverter and charger functions within the modules.

It says that the IBIS system also has the capability to reduce the cost of the EV powertrain, simplifying the manufacturing process, and (since the whole thing is lighter) it allows the vehicle to travel farther on a charge. In addition, the technology could be useful in stationary batteries, for generators and power banks.
