Imagine an EV battery that ditches bulky hardware and frees up space while adding range. Stellantis, the parent of Jeep, Dodge, Chrysler, Peugeot, and more, says it’s almost here.
Smarter Battery, No Extra Boxes
Most EVs need a charger and inverter to convert electricity back and forth. The new IBIS battery system does it all inside the pack. Each of its 24 modules is software-controlled, meaning power in and out is managed individually. No extra charger. No separate inverter.
The payoff? Less weight, less clutter, and better energy use. In tests, the system cut vehicle weight by about 88 pounds. That alone helps stretch range before even factoring in efficiency gains.
Real-World Results
Stellantis tested the IBIS battery inside a Peugeot e-3008 SUV. On Europe’s WLTC cycle, it used 10% less energy on the road and 10% less during charging. That shaved an hour off a standard home recharge.
Even better, the system delivered 15% more power to the motor compared to a standard inverter setup. That means snappier acceleration with the same pack.
More Space, More Potential
Freeing up space under the hood is a hidden win. Many EVs skip front trunks because chargers and inverters hog room. IBIS clears almost a cubic foot. That could improve aerodynamics too, nudging range even higher.
Built for Flexibility
Here’s where it gets futuristic: because every module is controlled separately, you could replace just one if it fails—or even mix different chemistries in the same pack. That means longer battery life and easier upgrades down the road.
The pack tested was 65 kWh with 288 nickel-manganese-cobalt cells. But Stellantis engineers say the concept could expand to larger, more powerful setups, including all-wheel drive.
What’s Next
The IBIS project involves 25 engineers, industrial partners, and research groups across Europe. With government funding backing the push, Stellantis says this tech could land in production models by 2030.
Final Spark
A 10% boost in efficiency may not sound like much, but in EV terms, it’s massive. For Stellantis, IBIS could be the key to hitting 300+ miles of range while freeing up space and cutting weight.
