— E-BUS TOSA flash-charging e-bus Enabling emission-free public transport in Geneva Catenary-free operation and 20-second charging at selected bus stops offers opportunities for the next generation of e-buses which are silent, flexible and emission free. — TOSA Urban mass transportation ABB will provide the core technology including The electric bus, named TOSA, looks like a regular Thanks to re-charging along the route, the battery the on-board traction trolleybus, except when you look on the roof. Instead size and weight have been reduced, resulting in equipment and the fully automatic flash-charging of the usual trolley poles which connect overhead increases in both space for passengers and energy system for an e-bus line lines, this e-bus has a controlled moving arm that efficiency. in Geneva, Switzerland. connects, in less than a second, to an overhead receptacle integrated into the bus shelter.

So passengers This technology eliminates the visual impact of the never have to wait for the bus to charge. overhead lines associated with trolleys and reduces noise emissions of diesel buses. By not being bound From concept validation to the deployment to the overhead lines the system also offers greater of the line 23 route flexibility.
