BMW, Mercedes, and Stellantis Begin Testing Solid-State Battery Technology

Solid-state battery technology, considered a major leap forward in electric vehicle innovation, is now under the spotlight of major automakers. BMW, Mercedes-Benz, and Stellantis have started testing this next-generation battery system.

BMW is collaborating with Solid Power to develop solid-state batteries and is currently testing the technology in a modified i7 prototype. The tests are being conducted in Munich, Germany. Meanwhile, Mercedes-Benz has begun road-testing solid-state batteries developed in partnership with Factorial Energy, integrated into an EQS prototype.

Stellantis is also working with Factorial Energy and plans to deploy a demo fleet by 2026. The first trials may take place in Dodge Charger EV models.

Solid-state battery technology aims to bring the following benefits to electric vehicles:

• Driving range exceeding 1,000 kilometers

• Faster charging times

• Lighter and safer battery structures

If this technology evolves as expected, it could mark the beginning of a major transformation in the world of electric vehicles.
