Stellantis just solved electric cars’ biggest problems with one simple change.
Key takeaways
- Stellantis unveiled its new all-in-one Intelligent Battery Integrated System (IBIS).
- This breakthrough design makes EVs lighter, more affordable, and roomier inside.
- It delivers up to 10% more range, quicker charging, and stronger power.
- Stellantis expects to roll it out in production models by the late 2020s.
If you’re thinking about buying your first electric vehicle or wondering if EVs are finally ready for everyday drivers, Stellantis just announced something that could change everything. Their new “all-in-one battery” technology promises to solve many of the problems that keep people from going electric.
What’s the Big Deal About This New Battery?
Think of a traditional electric car like a desktop computer – it has lots of separate parts that all need to work together. An EV usually has a battery pack, an inverter, a DC-to-DC converter and several other bits and bobs that live in different housings. These separate components take up space, add weight, and create more things that can break.
Stellantis’ new Intelligent Battery Integrated System (IBIS) is like switching from a bulky desktop to a sleek all-in-one computer. It simplifies an otherwise complicated layout by stuffing all the components into a single enclosure. Instead of having your battery in one place, charger in another, and power converter somewhere else, everything is combined into one smart unit.
What Does This Mean in Plain English?
Your Car Gets More Range (Without a Bigger Battery)
The prototype battery provides energy efficiency improvements of up to 10% compared to a conventional battery of the same size. This means if your current EV can drive 300 miles on a charge, this same-sized battery could potentially get you 330 miles. You’re getting more bang for your buck without needing a massive, expensive battery.
Faster Charging at Home
Nobody likes waiting around for their car to charge. On a 7 kW AC charger, Stellantis claims a full charge would take six hours on an IBIS battery instead of 7 hours. That might not sound like much, but when you’re charging overnight, every hour saved means more flexibility in your schedule.
More Power When You Need It
An IBIS-based battery can provide 230 horsepower (172 kilowatts), while a similar traditional battery can only output 201 hp (150 kW). That’s a 15% power boost, which means better acceleration and highway merging – important for drivers who worry about EV performance.
Your Car Gets Lighter and More Spacious
Here’s where it gets really interesting for everyday drivers. The all-in-one approach reduces weight by roughly 88 pounds (40 kilograms) and frees up to 0.6 cubic feet (17 liters) of space. That’s like removing a heavy suitcase from your car and gaining extra trunk space. Less weight means better efficiency, and more space means more room for your stuff.
Why Should Non-EV Owners Care?
It Addresses the Top EV Concerns
Range Anxiety: The 10% efficiency boost means you can drive further on the same battery, reducing those “will I make it?” worries.
Charging Speed: Faster charging means less time waiting and more time driving.
Reliability: Fewer separate components mean fewer things that can break down. Think of it like having one device instead of three – there’s less that can go wrong.
Cost: By combining multiple expensive parts into one unit, the overall system should be cheaper to manufacture, potentially leading to lower car prices.
Real-World Testing is Happening Now
This isn’t just lab science. The first working prototype has been fitted to a Peugeot E-3008 crossover, and Stellantis is testing it on real roads with real driving conditions. Phase 2 of the project began in June 2025 with continued support from the French Government, showing this is a serious, well-funded initiative.
What Cars Will Get This Technology?
Stellantis owns many brands you know: Jeep, Dodge, Chrysler, Ram, Fiat, and others. The E-3008 crossover uses Stellantis’s STLA Medium platform–the same that underpins the latest generation Jeep Compass. This means the technology could eventually appear in popular SUVs and crossovers that American families actually want to buy.
If it all goes to plan, the IBIS could make its way to Stellantis production EVs by the end of the decade. That means you could potentially buy a Jeep or Dodge with this technology in the late 2020s.
The Bottom Line for Everyday Drivers
Why This Matters More Than Other EV News
Most battery breakthroughs promise revolutionary changes that never materialize or take decades to reach real cars. This is different because:
- It’s being tested in actual cars right now
- It uses existing battery types – one nickel manganese cobalt (NMC) battery could just be taken off a shelf somewhere and fitted to a family-oriented EV
- The benefits are immediate and practical – more range, faster charging, more power
What It Means for Your Wallet
By rethinking and simplifying the electric powertrain architecture, we are making it lighter, more efficient, and more cost-effective, says Stellantis’ Chief Engineering Officer. Simpler systems typically mean:
- Lower manufacturing costs
- Cheaper repairs and maintenance
- Enhanced potential for second-life battery reuse, which could improve resale values
Should You Wait for This Technology?
If you’re considering an EV now, don’t necessarily wait. Current EVs are already great for most people. But if you’re on the fence about going electric, knowing that even better, more efficient EVs are coming soon might be the push you need to start seriously considering the switch.
This technology represents the kind of practical innovation that could finally make EVs appealing to mainstream buyers who want the benefits of electric driving without the compromises. These are the kinds of innovations that help us deliver better, more affordable EVs to our customers.
The Bigger Picture
Stellantis’ All-In-One Battery isn’t just about one company or one technology. It shows that the EV industry is maturing, moving beyond just making electric cars work to making them work better than traditional vehicles. When EVs offer more range, faster charging, better performance, and lower costs all in one package, the choice between gas and electric becomes a no-brainer.
For drivers who have been waiting for EVs to “get there,” technologies like IBIS suggest that moment is approaching faster than many expected.
