Solid-State EV Battery Charging 90% in 18 Minutes Enters Testing
The test vehicle uses a 375 Wh/kg pack that can charge from 15% to 90% in 18 minutes, Stellantis said.
- On Thursday, Stellantis announced the launch of real-world road testing for a Dodge Charger Daytona equipped with Factorial's FEST solid-state battery, marking the first integration of such cells into a company vehicle.
- Laboratory tests in 2025 demonstrated FEST cells with a claimed energy density of 375 watt-hours per kilogram and reliability across temperatures ranging from-22 degrees Fahrenheit to 113 degrees Fahrenheit.
- Engineers reworked the mechanical architecture and control systems to fit solid-state cells within the existing battery pack, enabling recharge from 15 percent to 90 percent in 18 minutes versus roughly 30 minutes for conventional lithium-ion packs.
- Last year, Factorial's semi-solid-state cells were installed in a Mercedes-Benz EQS prototype, which covered 749 miles on a single charge during a European road trip with 85 miles of range remaining.
- "This milestone shows we are bringing solid-state batteries closer to our customers," said Ned Curic, Stellantis Chief Engineering and Technology Officer, as the program aims to refine battery management systems before commercial deployment.

Solid-state EV battery charging 90% in 18 minutes enters testing
Stellantis has integrated Factorial Energy’s solid-state battery cells into a Dodge Charger Daytona development vehicle and begun road testing the technology, marking a key step toward bringing solid-state batteries into production vehicles. The milestone is the first time Factorial’s FEST (Factorial Electrolyte System Technology) solid-state cells have been installed in a Stellantis vehicle. The companies will now evaluate battery performance, …
Stellantis has started to test on the road a Dodge Charger Daytona equipped with solid-state batteries developed by the American company Factorial. This is the first integration of this technology into a group development vehicle and also one of the first applications of this type in North America.
Stellantis begins testing solid-state batteries in electric Dodge Charger
Automotive manufacturers have promised us a future filled with better, longer-lasting batteries for electric cars, and solid-state technology is the absolute pinnacle of these promises - the holy grail for EV engineers. Not to be left behind in the global race, Stellantis has officially taken this advanced technology out of the research lab and put it onto public roads, but instead of showcasing this high-tech battery inside a small, sensible ci…
