The city’s public transport operator is installing three Siemens fast charging units, including a charging mast with a top-down pantograph, at the Elfenau, Blinzern and Bremgarten terminal stations.
The Swiss capital of Bern’s public transport company has awarded Siemens a contract to supply charging infrastructure solutions for the operation of 14 new electric buses.
Bernmobil’s buses will operate on Lines 19 and 21, beginning in early 2023. The project includes fast charging units at three terminal stations as well as charging infrastructure for the Eigerplatz bus depot. To optimise operations, a cloud-based depot management solution from Siemens will be used as software-as-a-service (SaaS).
“Our goal is a completely climate-neutral bus network with 100 per cent electrically powered vehicles by around 2035,” said Markus Anderegg, deputy director and head of technology at Bernmobil.
“A reliable and efficient charging infrastructure is an important prerequisite for us to achieve our goal. With Siemens, we have a partner with whom we have had a long and good working relationship in the streetcar sector.”
Three Siemens Sicharge UC 600 fast charging units, including a charging mast with a top-down pantograph, will be installed at the Elfenau, Blinzern (Line 19) and Bremgarten (Line 21) terminal stations.
During their scheduled stops, the vehicles can be charged with a power of up to 450 kilowatts, Siemens reports. Connection of the charging unit to the vehicle is fully automatic so nothing needs to be connected manually. The charging mast has a height of 6.5 metres and weighs 2.5 tons; with a footprint of 130x33cm.
At the Eigerplatz bus depot, Siemens will install seven Sicharge UC 200 fast charging units, each with three dispensers. This means that a total of 21 bus parking spaces can be equipped with electric charging infrastructure.
The Siemens charging infrastructure, consisting of charging centres, dispensers and CCS2 connection cables, will be installed by Siemens in the existing depot during ongoing operations.
To manage the system, a digital depot management solution will be used in the Eigerplatz bus garage. Among other things, the system monitors all electrical currents, generates reports on charging operations, and enables efficient diagnostic and charging management.
“Along with the charging infrastructure, such digital systems are a key element for optimal depot operation. This gives our customers transparency over all charging processes and, as a result, control over their energy demand and costs,” added Birgit Dargel, global head of future grids at Siemens Smart Infrastructure.
