Stellantis Tests Solid-State EV Battery in Dodge Charger

A Leap Forward in Electric Vehicle Technology \\[Stellantis, the multinational automaker, has taken a significant step forward in electric vehicle (EV) technology by integrating Factorial Energy's solid-state battery cells into a Dodge Charger Daytona development vehicle. This move marks a crucial milestone in the journey towards bringing solid-state batteries to production vehicles, offering a glimpse of what the future holds for the automotive industry and, more importantly, for factories across Southeast Asia.\\The solid-state battery pack, which uses Factorial's FEST (Factorial Electrolyte System Technology), has been installed in a Stellantis vehicle for the first time. The companies will now evaluate the battery's performance, reliability, and safety under real-world driving and charging conditions. This follows laboratory validation completed in 2025, where the cells demonstrated an energy density of 375 Wh/kg, charged from 15% to 90% in just 18 minutes, and operated across a wide temperature range.\\### What This Means for ASEAN Factories \\For factories in Thailand, Vietnam, Indonesia, and Malaysia, this development could be a game-changer. The introduction of solid-state batteries with faster charging times and higher energy density can significantly reduce downtime and increase operational efficiency. In countries like Thailand, where the automotive industry is a key economic driver, the adoption of such advanced battery technology can enhance the competitiveness of local manufacturers. Similarly, in Vietnam and Indonesia, where the demand for electric vehicles is growing, the availability of reliable and efficient batteries can accelerate the transition to sustainable transportation.\\In Malaysia, where the electronics and semiconductor industries are thriving, the integration of solid-state batteries can also drive innovation in related sectors. The compatibility of FEST with existing lithium-ion manufacturing processes means that factories can leverage their current infrastructure to produce these advanced batteries, reducing the cost and complexity of transitioning to new technologies.\\### From Lab to Road \\Moving from laboratory testing to on-road trials required significant engineering efforts. Stellantis developed a patented mechanical architecture to fit the solid-state cells within an existing battery pack while maximizing performance. Engineers also modified battery controls and pack design to meet automotive requirements for durability and safety. This comprehensive approach ensures that the battery system performs consistently under a range of driving and charging conditions.\\### The Path to Commercialization \\With the battery now installed in a working vehicle, Stellantis and Factorial have launched a testing and calibration program to gather performance data from real-world operation. The results will help refine battery management systems and pack-level controls before any future commercial deployment. This is a critical stage in the development process, as it moves the technology beyond cell-level testing and into vehicle validation, a key step before potential mass-market adoption.\\### Conclusion \\The road-testing of solid-state batteries in the Dodge Charger Daytona represents a significant leap forward in EV technology. For factories in ASEAN, this development offers the potential for longer range, faster charging, and lower costs, all of which can enhance operational efficiency and competitiveness. As the technology matures and becomes more widely available, factory buyers should consider the benefits of adopting solid-state batteries to stay ahead in the rapidly evolving automotive landscape.\\
