The E-Bus China project focuses on the research and development of technical standards for electric buses, especially in the charging infrastructure, which open the way to closer trade between China and Germany. Both countries are addressing the problem of excessive CO 2 emissions with policy initiatives that encourage the switch from bus fleets to electric buses. The Technische Universität Berlin, in cooperation with the Beijing Institute of Technology and other partners, is working on a research project on charging strategies and system technologies for electrified city bus fleets to achieve this goal. This project comprises the investigation of the technical, operational and regulatory requirements for the use of common electrical bus system technologies in China and Germany as well as a detailed market analysis. Finally with proposals for technologies that meet the requirements of Chinese and German cities and become the basis for a future common market.
Germany and China share the goal of supporting the expansion of electric mobility as a resource-conserving technology. Bilateral academic research collaborations between the two countries are expected to make significant progress in innovative charging technologies and the efficiency of electronic components and systems. Among other things, the results will be used to further intensify German-Chinese standardization cooperation in the field of electromobility.
Goals and procedure
Within the framework of this project, the foundations for the cross-border application of electric bus system technologies in Germany, Europe and China will be developed. In a first step, the requirement profiles for E-bus systems will be determined and compared, on the basis of which suitable technologies for both markets will be identified. Finally, proposals for the harmonisation of technical standards for e-buses and charging infrastructure as a basis for a future common market will be developed. The focus of the investigations is on the charging infrastructure, as the requirements are highly dependent on local conditions. The resulting requirements for local power grids and adequate charging strategies for electric bus systems will also be considered.
Innovations and prospects
The systemic linking of bus traffic with the power grid extends the current state of the art. The analysis of requirement profiles and market structures creates the basis for potential export or joint venture activities of German bus and loading technology manufacturers in China.
