A major leap in electric vehicle battery innovation has arrived with the first real-world road test of a solid-state battery in North America. The new battery, integrated into a Dodge Charger by Stellantis and Factorial Energy, promises faster charging and lighter packs that could transform EV ownership.
- Solid-state batteries offer almost double the energy density of current EV batteries
- Can recharge from 15% to 90% in just 18 minutes with improved thermal stability
- First North American road test completed using a Dodge Charger as the test vehicle
What happened
Stellantis, a global automaker known for brands like Dodge and Chrysler, has partnered with Factorial Energy to test innovative solid-state battery technology in a real-world setting. A Dodge Charger test vehicle has been fitted with these new batteries, marking the first time this type of advanced battery has been installed in a road-worthy car in North America. The process involved redesigning the mechanical architecture of the battery pack and adapting control systems to accommodate the new battery cells.
This milestone follows earlier laboratory successes where the batteries showed impressive energy density—almost twice that of many current EV batteries—and rapid charging capabilities, able to reach 90% charge in under 20 minutes. While details on ongoing tests are still emerging, the move to in-car testing suggests production use could be on the near horizon.
Why it feels good
The shift to solid-state battery technology promises significant benefits for electric vehicle owners. These batteries replace the traditional liquid or gel electrolytes with a semi-solid electrolyte, combining the advantages of both states to improve ionic conductivity and thermal stability. This means safer operation, less fire risk, and better performance across a wide range of temperatures.
Beyond safety, the new batteries are lighter and smaller without sacrificing capacity, allowing EVs to potentially travel farther on a smaller battery pack. Faster charging times and enhanced energy efficiency alleviate common concerns about EV range and charging inconvenience. Together, these improvements bring us closer to more practical, everyday electric vehicles that can compete easily with traditional cars.
What to enjoy or watch next
As these solid-state battery tests progress, the automotive industry is watching closely. Stellantis’s pioneering effort in North America joins similar European trials from automakers like BMW and Mercedes, all racing to be the first to launch production EVs with solid-state packs. Other manufacturers such as Honda and MG are also advancing their own battery developments.
Consumers and EV enthusiasts should stay tuned for announcements as this technology moves from testing to commercial models. The promise of ultra-fast charging, safer batteries, and longer ranges could soon reshape the electric vehicle market and accelerate the transition to cleaner transportation.
