Winduction demonstrated an electric bus charging from a ground plate through coils in its tyres. Moving the receiving coils into the wheel reduces the transmission gap compared with underbody charging. The system needs specially developed steel-free tyres because conventional steel belts would absorb energy from the magnetic field as heat.
The company is building a laboratory and test bus stop in Winterthur before integrating the components for operation outside its private test area. Passenger trials are planned for 2028, with Swiss transport operators still in discussions. Smaller batteries and lower route costs are intended benefits, not results from a completed passenger-service trial.
