All-In-One Battery Promises More Range And Faster Charging In A Smaller Package

"By combining all the different components that usually sit outside an EV's battery pack into a single unit, the auto giant says it managed to cut charging times and reduce weight while boosting power and range. The solution is goes by the name Intelligent Battery Integrated System, and the first working prototype has been fitted to a Peugeot E-3008 crossover, which uses Stellantis's STLA Medium platform-the same that underpins the latest generation Jeep Compass."

"In practice, the IBIS embeds the inverter and charger functionalities directly into the battery, irrespective of the type of chemistry or application. This means that one nickel manganese cobalt (NMC) battery could just be taken off a shelf somewhere and fitted to an family-oriented EV. Or a lithium iron phosphate (LFP) battery could very quickly be integrated into a commercial electric vehicle."

The Intelligent Battery Integrated System (IBIS) integrates inverters, chargers, DC-to-DC converters, and other power electronics into a single enclosure around the battery pack. The integrated architecture reduces weight and external housings, shortens charging times, and increases driving range and energy efficiency. The IBIS supports both AC and DC charging, supplies power to motors and the grid via vehicle-to-grid (V2G) capability, and powers 12-volt and auxiliary systems. The design accepts multiple chemistries such as NMC and LFP, simplifying module interchangeability. Prototype testing on a Peugeot E-3008 reports up to 10% energy efficiency improvement and a 15% power gain versus conventional batteries.
