SBRS congratulates Kölner Verkehrs-Betriebe AG on winning the Mobility Award.NRW
KVB has won third place in the Mobility Award.NRW with the new Porz e-bus depot. The prize is awarded by the Alliance for Mobility in the Ministry for the Environment, Nature Conservation and Transport of North Rhine-Westphalia (MUNV). Around 130 actors work with partners from the public sector, business, science, the transport industry, and associations to create simple, flexible, and climate-neutral mobility in North Rhine-Westphalia.
SBRS warmly congratulates on the – in our opinion – highly deserved award!
The Porz e-bus depot is a significant milestone in the “Smart City KVB” project, which will convert the entire bus operation in the KVB network to electric drives by 2030. The first pure e-bus depot in North Rhine-Westphalia, with space for up to 180 buses, was built on the approximately 63,000 m2 site.
The core of the “green depot” is the charging infrastructure built by SBRS GmbH. In two transformer buildings, the green electricity supplied by RheinEnergie is being transformed to 400-850 V DC charging voltage, with energy-efficient charging rectifiers playing a decisive role. Currently, 22 sequential 150 kW chargers, 8 solo chargers and a 450 kW fast charger are in use at the Porz depot. The power flows are distributed via cables along the traverses to the predominantly sequentially controlled two charging hoods per charger. Through the contact of the bus pantographs to the charging hoods, the required data on the bus battery’s charging volume, the time available for charging, and the next planned line operation are exchanged, and the required amount of electricity is requested.

An important role for all charging processes is played by the charging management system, which was included in the delivery of the charging technology. This communicates between buses, chargers, and depot management, enabling optimal utilization. Since environmental protection was a high priority in the planning of the new depot, nine photovoltaic systems were placed on the roofs and traverses of the charging infrastructure, generating up to 440 kWh of electricity at peak times. The roofs and many facades of the buildings are greened, and the buildings themselves are low-energy constructions.
In addition, rainwater is directed to infiltrate rather than flow into the sewer system. Trees were planted in the peripheral areas of the site, and a 900 m² biotope for wall lizards was created.
We are proud to contribute to this pioneering project and thus advance another building block of the mobility transition.
