Solid-State EV Battery Module Promises 1,000 km Range

On January 5, ProLogium Technology confirmed plans to co-exhibit with FEV Group at CES 2026, where both companies will showcase a next-generation solid-state EV battery module designed to significantly extend electric vehicle driving range while improving efficiency and safety. The concept is built on ProLogium’s superfluidized all-inorganic solid-state lithium ceramic battery technology.
The solid-state EV battery module is engineered to support electric vehicles with a driving range of up to 1,000 km, marking a major step forward in long-range EV development. The program has already progressed to the sample car-ready stage, indicating readiness for integration into demonstration vehicles and further validation under real-world operating conditions.
Lightweight Battery Design Enhances Vehicle Efficiency

• By achieving equivalent driving range using a smaller-capacity battery system, the solid-state EV battery module allows overall vehicle weight reduction of up to approximately 300 kg.

Lower vehicle mass directly improves energy efficiency, handling performance, and overall vehicle dynamics, while also enabling automakers to optimize chassis and powertrain design. The compact battery architecture also provides greater flexibility in vehicle packaging, supporting future EV platforms focused on aerodynamics, interior space optimization, and improved energy utilization without increasing battery footprint.
Ultra-Fast Charging With Safety at the Core

• One of the most notable capabilities of the solid-state EV battery module is its ability to reach 60–80% state-of-charge in just 4–6 minutes.

This ultra-fast charging performance is achieved without compromising safety, addressing one of the most critical challenges facing next-generation EV adoption. Solid-state battery chemistry reduces thermal risk and improves structural stability, making high-power charging cycles safer and more reliable compared to conventional lithium-ion systems.
Advanced Thermal Management and BMS Integration
FEV Group contributes extensive expertise in battery system engineering, including thermal management and battery management system integration. The collaboration incorporates FEV’s Thermal Propagation optimization process, designed to minimize heat transfer risks and enhance system-level safety during high-load and fast-charging conditions.
In addition, advanced BMS control strategy integration ensures precise monitoring of cell behavior, thermal balance, and energy flow, further improving performance consistency and long-term durability of the solid-state EV battery module.
Together, these developments highlight how solid-state battery technology is moving closer to commercialization, with real-world-ready modules that address range anxiety, charging speed, vehicle weight, and safety in a single integrated solution.
