Geneva Electric Buses Charge in 15 Seconds



A new charging system for electric buses known as “flash-charging” can charge buses in 15 seconds. This means that buses can transport people without producing any local emissions, requiring overheard power lines, and avoiding lengthy stops to recharge. The flash charger uses a laser-controlled arm to connect the receptacle on the bus with the charger, which could be integrated into the bus stop itself. This type of system could allow for electric buses to replace trolleys and subway systems in urban areas, and in the process, get rid of unsightly overhead power lines used to feed them.

The new technology, developed by ABB, will be put into operation on a large capacity electric bus in Geneva, Switzerland, as part of a pilot project called Trolleybus Optimisation Système Alimentation (TOSA). The pilot project will be operating bus runs between the Geneva airport and the city’s international exhibition center, Palexpo. According to ABB, the bus can be charged with a 15 second, 400 kilowatt boost at selected stops, which allows for the vehicle to top off its charge while the passengers are loading or leaving the bus, and a 3 to 4 minute charge at the end of the bus line will then fully recharge the batteries.
