Stellantis Integrates Factorial’s 375 Wh/kg Solid-State Battery in Dodge Charger Development Vehicle
FAC•Stellantis has integrated Factorial’s FEST® solid-state cells with 375 Wh/kg energy density into a Dodge Charger Daytona development vehicle, marking the first North American automotive integration. Road testing has begun to validate ultra-fast charging from 15% to 90% in 18 minutes and assess performance, safety and reliability under real-world conditions.
1. First Automotive Integration of FEST® Cells
Stellantis engineers integrated Factorial’s FEST® solid-state cells into a Dodge Charger Daytona development vehicle, representing the first application of this technology in a Stellantis model. A new patented mechanical architecture was designed to fit the cells into the existing battery pack while maintaining compatibility with lithium-ion manufacturing processes.
2. Industry-Leading Performance Metrics
Factorial’s FEST® cells offer 375 Wh/kg energy density and support ultra-fast charging from 15% to 90% in just 18 minutes. These cells have demonstrated robust reliability across –30 °C to 45 °C, underscoring their suitability for automotive-scale applications.
3. Road Testing and Calibration
Stellantis and Factorial have launched a comprehensive road testing and calibration program to validate pack performance, safety and reliability under diverse driving and charging scenarios. Data from real-world testing will inform control system tuning and durability assessments.
4. Path to Commercialization
This integration milestone advances Factorial’s efforts to industrialize solid-state battery production for automotive use and accelerates Stellantis’s roadmap for next-generation EVs. Strong compatibility with existing lithium-ion lines could enable faster scale-up and deployment in future Stellantis models.
