Zurich orders electric bus charging from Siemens



In Switzerland, Siemens won a contract from the Zurich Transport Authority (VBZ) for the supply, installation and commissioning of 45 Sicharge UC charging stations for electric buses. The charging infrastructure will be installed in the Hardau bus garage for 45 new electric buses.

Siemens indicates that the system should come into service at the beginning of 2022. The order is distributed between 30 Sicharge UC stations of 100 kW and 15 stations of 150 kW. Vehicles must be recharged via the CCS cable “mainly during night breaks”.

With the charging stations, VBZ is preparing to extend its fleet of electric buses. In March, VBZ ordered four articulated electric buses from MAN and announced in early July that the city council had approved funding for 15 additional electric buses. This will be used to purchase the twelve-meter solo bus version of the MAN Lion’s City, a total of 19 electric buses at present, which are expected to enter service in 2022. However, the framework agreement with MAN also includes options. to purchase 29 other standard electric buses and 80 articulated electric buses.

“In order to modernize our existing garages for eBus operation as smoothly as possible, it was important for us to find a charging infrastructure that offered flexible integration,” explains Christoph Rütimann, Vice-Director and Head of Technology at VBZ. “The Siemens charging solution is exactly what we were looking for. “

Siemens highlights a special feature of the solution for Zurich: the supply of the charging cable from the ceiling. “Existing garages are often not designed to be fitted with charging infrastructure, and it is important not to disrupt ongoing operations when installing the necessary equipment,” said Birgit Dargel, Global Head of Networks future at Siemens Smart Infrastructure. “We will install a matching cable suspension system, which also requires very little maintenance compared to other common cable drums. As a result, the passages will remain clear and incoming and outgoing vehicles will not be hampered. “

Siemens recently won a contract for another electric bus charging infrastructure project in Switzerland by the Bern public transport authority. The project includes fast-charging stations at three terminal stops as well as a charging infrastructure for the Eigerplatz bus depot.
