The northern Italian city of Torino has a population of 2.2 million, including its metropolitan area.
In 2003 Torino launched a fleet of electric buses serving its historic centre, newly converted into a ‘limited traffic zone’.
An inductive charging system is used along the bus routes, enabling an efficient wireless recharge of batteries. The system consists of primary coils connected to the electrical grid, and a secondary coil integrated into the floor of each electric bus. The batteries are fully charged overnight and topped up during the day along the bus route - at terminals and railway stations, for example.
Thanks to these short and relatively frequent charging sessions, the buses - that accommodate 40 passengers - can operate 13 hours without interruption, travelling about 130km a day at a maximum speed of 70 km/h. All without vibrations, noise or emissions.
The success led Torino to launch a second line in September 2007, using the same system.
