Stellantis, the auto giant, has introduced a groundbreaking solution for electric vehicles (EVs) called the Intelligent Battery Integrated System (IBIS). This innovative system simplifies the layout of EV components by integrating them into a single enclosure within the battery pack.
Traditionally, an EV consists of a battery pack, inverter, DC-to-DC converter, and various other components housed separately. This setup is not very energy efficient. However, with the IBIS, Stellantis has managed to streamline the design, resulting in improved energy efficiency, reduced weight, and enhanced performance.
The first working prototype of the IBIS has been installed in a Peugeot E-3008 crossover, which is based on Stellantis’s STLA Medium platform. This platform also underpins the latest generation Jeep Compass. The IBIS integrates the inverter and charger functionalities directly into the battery, regardless of the battery chemistry or application.
This means that different types of batteries, such as nickel manganese cobalt (NMC) or lithium iron phosphate (LFP), can be easily integrated into various EV models. The IBIS supports both alternating and direct current (AC and DC) and can supply power to electric motors, the grid, and the vehicle’s 12-volt and auxiliary systems. It also offers vehicle-to-grid (V2G) functionality.
According to Stellantis, the IBIS prototype offers energy efficiency improvements of up to 10% and a power gain of 15% compared to traditional batteries of the same size. This translates to a power output of 230 horsepower (172 kilowatts) for an IBIS-based battery, compared to 201 hp (150 kW) for a conventional battery.
Moreover, the IBIS reduces weight by approximately 88 pounds (40 kilograms) and frees up space equivalent to 0.6 cubic feet (17 liters) in the vehicle. Charging speeds have also been enhanced, with a full charge on a 7 kW AC charger taking six hours instead of seven hours with the IBIS battery.
Stellantis plans to validate the IBIS in real-world testing and aims to incorporate it into production EVs by the end of the decade. This revolutionary system has the potential to revolutionize the EV industry by improving energy efficiency, performance, and charging times. Stay tuned for more updates on Stellantis’s IBIS technology.
