ABB to optimise e-bus operations in Geneva

TOSA e-bus

ABB Ability solution to provide Geneva’s public transport operator with real-time data and insights

ABB announced that Transports publics genevois (tpg), Geneva’s public transport operator in Switzerland, has placed an order for an ABB Ability based solution comprising a supervisory control and data acquisition (SCADA) system and enterprise asset management (EAM) software. The solution will help optimize the TOSA (Trolleybus Optimisation Système Alimentation) fully electric buses (e-buses).

The ABB Ability Network Manager SCADA system will be used to monitor and control the power network for the charging stations and e-buses, maximising availability and operational efficiency. It will be integrated with the ABB Ability Ellipse Select, EAM software with embedded best-practice parameters and industry specific workflows. This will further optimise maintenance processes, enable a fast response to fault incidents and better predict maintenance needs. The overall solution is also equipped with remote access and ‘cloud’ capabilities and is scalable to meet future needs.

In 2016, ABB was contracted by TPG and Swiss bus manufacturer HESS, to provide flash charging and on-board electric vehicle technology for 12 TOSA e-buses for Line 23, which will connect Geneva airport with the suburbs. This route is expected to carry 10,000 passengers a day and is supported by the Swiss Federal Office of Energy (SFOE) as part of a flagship programme.

As part of this project, ABB is deploying 13 flash-charging stations, three terminal and four depot feeding stations along the transit bus route. The flash-charging connection technology will be the fastest in the world, connecting the bus to the charging point in less than 1 second. The onboard batteries can then be charged in 15 seconds with a 600-kilowatt power boost 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 e-buses require no overhead lines and offer silent and zero-emission mass transit solution as a viable alternative to diesel buses, providing a model for future urban transportation.
