Hamburg-Holstein Public Transport (vhh.mobility) planned to add 78 charging points to its Bergedorf bus depot to meet the rising number of electric buses. The site is VHH's largest depot and houses both the administration and an eBus workshop.
The chargers are arranged in a herringbone pattern in the outdoor area of the depot. This design not only enables efficient use of space but also provides easy access to the charging station. The one-to-one setup allows buses to be quickly recharged during peak hours and returned to circulation after a short break. At the customer's request, the chargers were also fitted with prominent markings to effectively prevent collisions with vehicles.
Thanks to the conversion of the depot, 78 buses in Bergedorf can be charged with renewable energy. With more than 785 buses, VHH is the third largest municipal bus company in Germany. It currently operates 17 bus depots in Hamburg and Schleswig-Holstein. By the 2030s, the entire fleet will be converted to zero-emission vehicles. More than 280 electric buses are already in service.
Heliox and TU/e aim to develop an integrated solution that makes charging heavy electric vehicles accessible without negative consequences for local electricity networks. Together, we want to achieve this by developing and demonstrating a new, multiple and dynamic charging system for heavy electric vehicles that is equipped with software-controlled stabilization to absorb disturbances on the local energy grid.
The intended system will consist of a dynamically configurable charging system based on modules that can be connected in parallel, each with three 60 kW outputs. With this they want to be able to distribute the loading capacity dynamically over several vehicles. The charging system can therefore be used for opportunity charging up to 360 kW for a single vehicle as well as for regular charging of several vehicles.
In addition, smart software and a microcontroller board are being developed. The converter of the charging system can be used via this software to compensate for grid disturbances. The disturbances are neutralized via a low impedance path. This allows losses on the grid to be converted into usable energy, while improving the voltage quality of the grid. In fact, the system completely takes over the function of current power filters on the basis of smart control.
