Winduction Develops Cable-Free Bus Charging Through Special Tyres

Winduction is developing a bus that can charge without plugging in.

The bus stops over a special plate built into the road.

Coils in the plate create a magnetic field.

Coils inside the bus’s specially designed tyres pick up energy from that field.

The energy then goes to the bus’s battery.

Winduction says putting the receiving coils in the tyres brings them closer to the road than coils under the bus would be.

The company says more than 90% of the energy makes it from the road to the vehicle.

The special tyres need a new, steel-free design.

The technology is still being tested, so passengers cannot use it yet.
