It takes a second to connect and onboard batteries can then be charged in 15 seconds with a 600-kilowatt boost of power at the bus stop
ABB has secured its first order to deploy ultrafast charging technology for electric buses in Geneva, Switzerland.
The $16m order from Geneva’s public transport operator, Transports Publics Genevois (TPG), and domestic bus manufacturer Hess will see ABB deliver and deploy flash charging as well as on-board electric vehicle technology for 12 fully electric buses (e-buses).
As a result, 13 flash-charging stations will be positioned on the ‘Line 23’ bus route which runs from Geneva Airport. The technology takes less than a second to connect the e-bus to the charging point and the onboard batteries can then be charged in 15 seconds with a 600-kilowatt boost of power at the bus stop, which according to ABB is the world’s fastest. The order also comprises three terminal and four depot feeding stations which will enable a full recharge of the batteries in four- to five minutes.
The 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,” said Claudio Facchin, president of ABB’s power grids division. “It provides a model for future urban transport and reinforces our vision of sustainable mobility for a better world.”
The decision to deploy the so-called TOSA (Trolleybus Optimisation Système Alimentation) on Line 23 was undertaken after a successful pilot of the first such e-bus on the route from Geneva airport to the Palexpo exhibition centre.
The Line 23 bus route will be slightly modified in order to provide a fast connection to Praille-Acacias-Vernet, a new suburb being built to accommodate 11,000 flats and office space for about 11,000 employees.
When fully commissioned in 2018, the high-capacity articulated buses will depart from both terminuses at 10-minute intervals during peak times. The line carries more than 10,000 passengers a day and the replacement of diesel buses by TOSA e-buses can help save as much as 1,000 tons of carbon dioxide per year, the company said.
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 (ETS), as well as permanent magnet traction motors. Both contracts include five-year maintenance and service agreements.
