* Switzerland - Electric bus takes 15 seconds to receive an energy boost
* Swiss - TOSA tech charges up electric buses in 15 seconds
(Picture: A new flash-charging system for electric buses delivers 15-second-long battery boosts at selected stops) Geneve,Switzerland -Gizmag, by Ben Coxworth -June 4, 2013: -- In Geneva, however, they’re trying something else: a system in which an electric bus takes 15 seconds to receive an energy boost at selected stops... Billed as “the world's first high-capacity flash charging electric bus system,” the technology was created by the Zurich-based ABB Group. The system is known as TOSA, or Trolleybus Optimisation Système Alimentation [Optimizing Power System]. Here’s how it works ... The bus begins its route with a fully-charged battery. At every third or fourth stop, a charging mechanism on the roof of the bus engages an overhead receptacle that’s installed at the stop. The charging mechanism is mounted on a movable arm, and is able to line itself up with the receptacle using a laser guidance system. Once the two devices are coupled, the receptacle delivers a 15-second-long 400-kilowatt boost to the bus’ batteries. This takes place as passengers are getting on and off of the bus...
