Under the hood
Osnabrück e-buses are charged at night in the depot
Osnabrück is currently regarded as a nationwide pioneer in the switch to electric public transport. To ensure that e-buses do not run out of power, we ensure this for and with our contracting company SBRS, a Shell subsidiary specializing in modular fast-charging systems for e-buses.
SBRS is relying on our expertise to develop the charging infrastructure for public transport in Osnabrück. “With SCHULZ, we have a reliable and experienced partner at our side who is familiar with all the components of sustainable charging solutions,” said Andreas Stahl, Managing Director of SBRS GmbH.
Intelligent charging technology for public transport: A total of 84 buses can now dock overnight at the Osnabrück municipal bus depot for recharging.
We have currently jointly equipped a bus depot for a total of 84 vehicles, which can dock there for charging in bays. “SBRS has the task of setting up the charging infrastructure from low-voltage distribution. That means we installed the chargers, laid the cables from the low-voltage distribution board to the charger and from the charger to the charging hood,” said Tobias Büssing, Energy Technology Team Leader in Wallenhorst, explaining the scope of work. But first, before the 84 chargers with a total output of six megawatts could be installed, the building needed an upgrade. “Stadtwerke Osnabrück first built a hall within the hall, because the statics were not designed for the entire building. The charging infrastructure is now self-supporting in the hall,” explained Büssing. At the bus depot, the vehicles have all night to charge at stations with 75 KW and 50 KW charging power.
Charging must be faster when the vehicle is in operation: “For this purpose, we have equipped terminal stops with Opportunity Charging – these are 350 kW fast chargers. We supplied the medium-voltage section and connected the transformers, chargers and masts,” added our energy technology team leader. This allows bus drivers to charge efficiently between journeys and then start their next tour.
“Before the 84 chargers could be installed, the building needed a structural upgrade. The charging infrastructure is now self-supporting in the hall.”
