Winduction offers a wireless inductive power transfer system that embeds high‑frequency receiving coils in electric vehicle wheels, enabling up to 40 kW per wheel (160 kW total) to be delivered from specially equipped road segments with >90 % efficiency. The technology allows brief, on‑the‑move charging from renewable grid sources, reducing required battery capacity and extending range, and is available as retrofit kits for manufacturers and as licensed infrastructure for road operators.

Problem
Electric vehicles depend on stationary charging stations and large onboard batteries, which limits range, increases vehicle weight, and often requires grid electricity generated from non‑renewable sources. During periods of high renewable generation, many vehicles are already on the road, preventing efficient use of surplus clean energy. Consequently, the charging infrastructure struggles to meet demand without costly grid‑scale storage.
Solution
Winduction provides a wireless inductive power transfer system that integrates high‑frequency receiving coils directly into each vehicle wheel. When a wheel passes over a specially equipped road segment, the system establishes an ultra‑tight air gap and transfers up to 40 kW per wheel (160 kW total) with greater than 90 % efficiency, drawing real‑time renewable electricity from the grid. The technology eliminates the need for prolonged plug‑in sessions and reduces the required battery capacity, extending vehicle range with only brief stops. Its modular design supports retrofit kits for existing EV platforms and can be scaled across municipal road networks. Data on power transfer and system health can be monitored remotely, enabling operators to manage the charging infrastructure as a service.
Target Audience
Primary customers are electric vehicle manufacturers and fleet operators seeking to reduce battery size, as well as road authorities and charging network providers looking to deploy wireless charging lanes at scale.
