Electrification of public bus transport in Königsbrunn with the AVV
The Augsburg Transport and Tariff Association (AVV) has taken a significant step towards a sustainable and low-emission future with the electrification of city bus transport in Königsbrunn. As part of this project, modern, 12-meter-long Ebusco 2.2 electric buses are gradually replacing the previous diesel vehicles. The successful implementation of this project was made possible by forward-looking planning and the partnership with Kempower, a leading provider of charging infrastructure solutions.
The project in Königsbrunn builds on a successful pilot project in the Augsburg district, which was already implemented in 2020. This not only demonstrated the performance of electric buses, but also demonstrated the significant advantages in terms of noise and CO2 reduction as well as improved comfort for passengers and driving staff.
The pilot project not only demonstrated the performance of the eBuses, but also showed that they significantly reduce noise and CO2 emissions and increase comfort for both passengers and driving staff.”
emphasizes Dr. Linda Kisabaka, managing director of the AVV. This positive balance and the experiences from the pilot project formed the basis for the decision to convert the bus fleet in Königsbrunn to electric operation.
Intelligent technology and early planning as success factors
The electrification of buses places high demands on the charging infrastructure. This not only has to be reliable and efficient, but also flexible enough to meet the different charging requirements of the buses. What was crucial for the successful implementation of the project was that the charging infrastructure was planned into the existing depot in Bobingen at an early stage.
It was essential for the operators that the existing bus depot could be used optimally and adapted at the lowest possible cost. This is also why the AVV chose Kempower’s charging solutions. Six Kempower Satellites are used at the Bobingen location, offering flexible charging power of 150 to 600 kW.
By using Kempower’s ChargEye technology, the buses can be optimally charged. The cloud-based charging management system monitors the charging processes and enables dynamic power distribution so that the buses’ idle times can be optimally used.
Philipp Oppolzer, Business Development Director in Central Europe, Kempower, explains: “In order to electrify bus fleets cost-effectively, it is also important to correctly dimension the appropriate charging infrastructure. Not every bus needs its own charging station. Rather, it is important to analyze the entire energy requirement and the downtimes of the vehicles in order to design a charging solution that is optimized for operation.”
He continues: “Traditional charging systems require that each station be designed for maximum charging power. However, with Kempower’s intelligent dynamic power allocation to multiple charging points, fewer power modules are used overall for the same charging requirement. A dynamic, optimized store has a significant impact on the investments to be made and the running costs.”
Low-emission transport in Königsbrunn
With an annual mileage of 580,000 scheduled kilometers, the electric buses in Königsbrunn will save around 224 tons of CO2 annually, based on the current energy mix. If you switch to green electricity, these savings could even increase to 551 tons of CO2.
The successful electrification of city bus transport in Königsbrunn shows how the switch to electric mobility in local public transport can be implemented efficiently and effectively through careful planning and the use of modern, intelligent charging infrastructure. This project not only serves as a model for similar projects in other cities, but Königsbrunn also makes a significant contribution to reducing CO2 emissions and promoting sustainable mobility.
