Donut Lab (Espoo, Finland) develops an integrated EV platform combining a company‑reported 400 Wh/kg all‑solid‑state battery with ~5‑minute charging, high‑torque in‑wheel motors, embedded control electronics and DonutOS digital‑twin software for vehicles and industrial systems.
Donut Lab’s core technology centers on a company‑reported all‑solid‑state battery with a claimed cell‑level energy density near 400 Wh/kg, full charge capability in roughly five minutes and a design life up to 100,000 cycles. The cell chemistry uses non‑flammable solid electrolytes intended to reduce thermal‑runaway risk and expand operating temperature range. Supporting systems include high‑torque in‑wheel Donut Motor designs, integrated control electronics (MCUs/ECUs/VCUs/BMS) and DonutOS, a digital‑twin environment for system‑level simulation, validation and software calibration before hardware production.
Donut Lab supplies Donut Battery cells and modular packs, Donut Motor in‑wheel propulsion units, Donut Control electronics and DonutOS digital‑twin software. The platform is modular and configurable for motorcycles, lightweight EV skateboards, trailers, drones, robotics, defense vehicles and stationary energy storage, offering claimed benefits in energy density, charging speed and simplified vehicle architectures.
Verge Motorcycles — Verge TS Pro (2025–2026): Donut Lab supplies its all‑solid‑state battery and in‑wheel motor for the Verge TS Pro, promoted as the first production motorcycle using this battery technology. The program moved into production development with deliveries planned for Q1 2026, demonstrating vehicle‑level integration of Donut Lab’s platform.
Donut Lab completed funding rounds raising approximately €15 million in 2024 and €25 million in July 2025. Publicly disclosed backers include Risto Siilasmaa, who serves on the company’s board. Raised capital has supported technology development, platform demonstrations and early commercial deployments with OEM partners.
