1st commercial e-bus in Geneva by ABB
Print Edition
REVOLUTIONARY technology which requires no overhead lines and offers silent and zero-emission mass transit solution as a viable alternative to diesel buses provides a model for future urban transport.
ABB has been awarded orders totaling more than US$16 million by Transports Publics Genevois, Geneva’s public transport operator, and Swiss bus manufacturer HESS, to provide flash charging and on-board electric vehicle technology for 12 TOSA (Trolleybus Optimisation Système Alimentation) fully electric buses which will run on Line 23, connecting Geneva’s airport with suburban Geneva. The e-buses can help save as much as 1,000 tons of carbon dioxide per year, when compared with current diesel buses.
ABB will deliver and deploy 13 flash-charging stations along an urban transit bus route, as well as three terminal and four depot feeding stations. This will be the world’s fastest flash-charging connection technology taking under 1 second to connect the bus to the charging point. The onboard batteries can then be charged in 15 seconds with a 600-kilowatt boost of power at the bus stop. A further 4-to-5 minute charge at the terminus at the end of the line enables a full recharge of the batteries. The innovative technology was developed by ABB engineers in Switzerland.
“We are proud of this breakthrough technology to support Geneva’s vision of providing a silent and zero-emission urban mass transportation for the city. It provides a model for future urban transport and reinforces our vision of sustainable mobility for a better world” said Claudio Facchin, president of ABB’s Power Grids division.
The decision to deploy TOSA on Line 23 was made after the successful pilot of the first such e-bus on the route from Geneva airport to the Palexpo exhibition center. The Line 23 bus route will be slightly modified to provide a fast connection to Praille-Acacias-Vernet, a new suburb being built for 11,000 flats and office space for about 11,000 employees.
As part of a separate award by HESS, ABB will supply 12 flexible drivetrain solutions for the buses including integrated traction and auxiliary converters, roof-mounted battery units and energy transfer systems, as well as permanent magnet traction motors.
