Tyres instead of a plug: electric buses that charge during operation
ETH spin‑off Winduction has developed a wireless charging system that uses coils inside bus tyres to draw power from ground plates at stops, allowing electric buses to recharge during operation. The system achieves over 90% efficiency and enables smaller batteries, reducing acquisition and operating costs. A pilot is planned for 2028 with Swiss transport operators, including a route between Zurich Airport and Oerlikon.
