Stellantis's Revolutionary All-in-One Battery System: Enhanced Range, Faster Charging, and Compact Design










Stellantis has introduced a pioneering battery system, the Intelligent Battery Integrated System (IBIS), which integrates crucial EV components into a single unit. This innovation is set to redefine electric vehicle performance by enhancing driving range, accelerating charging times, and optimizing power delivery. By consolidating the battery, inverter, and charger, IBIS aims to overcome traditional limitations, offering a more streamlined and efficient power solution for electric cars.
Electric vehicles typically house various power components like the battery pack, inverter, and DC-to-DC converter in separate locations, leading to inefficiencies. Stellantis's IBIS tackles this issue by embedding all these functionalities directly within a singular battery enclosure. This strategic consolidation not only improves energy efficiency but also contributes to a lighter and more compact overall system.
The first functional prototype of the IBIS has been successfully installed in a Peugeot E-3008 crossover, utilizing Stellantis's STLA Medium platform. This platform also supports other models, including the latest Jeep Compass. The modular design of IBIS allows it to accommodate different battery chemistries, such as nickel manganese cobalt (NMC) for passenger cars and lithium iron phosphate (LFP) for commercial vehicles, demonstrating its versatility.
Developed in collaboration with Saft, the IBIS system supports both alternating current (AC) and direct current (DC) inputs and outputs. It boasts vehicle-to-grid (V2G) capabilities, enabling it to supply electricity not only to the vehicle's motors but also to the power grid, while concurrently managing the vehicle's 12-volt and auxiliary electrical systems.
Preliminary tests indicate substantial improvements with the IBIS battery. It offers up to a 10% increase in energy efficiency and a 15% boost in power output compared to conventional batteries of comparable size. This means an IBIS-equipped vehicle can deliver 230 horsepower, surpassing the 201 horsepower of a traditional setup. Furthermore, the integrated design shaves off approximately 88 pounds (40 kilograms) from the vehicle's weight and frees up about 0.6 cubic feet (17 liters) of space.
Charging speed has also seen a notable enhancement. A full charge with a 7 kW AC charger takes roughly six hours with an IBIS battery, an hour less than the seven hours required by standard batteries. The next critical step involves real-world validation of this integrated packaging system. If testing progresses as expected, Stellantis anticipates integrating IBIS into its production electric vehicles before the end of the decade.
This innovative approach represents a significant leap forward in electric vehicle battery technology. By simplifying the complex architecture of EV power systems, Stellantis is paving the way for electric vehicles with greater range, faster charging, and improved overall performance, ultimately enhancing the user experience and accelerating the transition to sustainable transportation.
