ProLogium Technology, a developer of solid-state batteries, is partnering with Germany’s FEV Group to showcase a next-generation electric vehicle battery module at the Consumer Electronics Show (CES) 2026 in Las Vegas. The concept module leverages ProLogium’s proprietary superfluidized all-inorganic solid-state lithium ceramic technology, aiming to deliver high energy density, ultra-high safety, fast-charge capability, and strong performance at low temperatures. Early prototypes have already reached the sample car-ready stage, with a targeted driving range of up to approximately 1,000 kilometers.
Building on a collaboration agreement signed in 2022, ProLogium provides the solid-state cell innovation while FEV contributes system-level design expertise, including thermal management optimized through its Thermal Propagation process and integrated battery management system (BMS) controls. This joint approach offers automakers greater flexibility in chassis packaging and can increase system energy density within existing battery pack volumes or reduce overall vehicle mass, potentially improving acceleration and efficiency.
According to joint assessments, the battery module can be configured for either “maximum range” or “maximum lightweight” applications to meet diverse original equipment manufacturer (OEM) requirements. In the maximum range setup, high-energy-density modules can reach the 1,000-kilometer goal within the same package size. In the lightweight configuration, achieving the same range with a smaller-capacity system could cut vehicle weight by as much as 300 kilograms, lowering battery costs and enhancing efficiency.
The module also aims to support rapid charging, with potential to reach 60–80% state-of-charge in four to six minutes under appropriate system and charging strategy designs, all without compromising safety. To demonstrate manufacturing readiness, the production of prototype samples will be documented in time-lapse video, highlighting transparent, scalable mass-production processes.
ProLogium is advancing toward localized supply with a planned gigafactory in Dunkirk, France, while FEV continues to apply its broad engineering and integration capabilities. Their joint effort underscores progress toward bringing solid-state battery technology from concept to OEM-ready solutions.
