eBus Executive summary
Electric buses and testing environment: eBus-Veolia (Veolia)
Electric buses and testing environment: eBus-RES (VTT)
The term 'eBus' refers to the entity consisting of work packages eBus-RES and eBus-Veolia. As a part of the Electric Commercial Vehicles (ECV) project entity, eBus forms a world-class testing environment for electric buses in the Helsinki metropolitan area, with Espoo as the centre of activity. The challenging climate, participation of key Finnish companies, research organisations and the public sector, the commitment of an internationally significant bus operator, and the seamless cooperation between the parties, combine to create a unique testing environment.
The eBus testing environment consists on the one hand of testing electric buses in the prototype and pre-production stages in the internal public transport of Espoo and the related measuring and research activities, and on the other of a testing platform (prototype electric bus), which provides the opportunity for Finnish parties to develop and test their components and subsystems. The eBus platform forms a point of contact between actors in the Finnish electric vehicle cluster and the international car industry.
The eBus prototype “Mule” – a testing platform for an electric powertrain
The core research task of the eBus project is the development of a testing mule to enable the testing and optimisation of components and subsystems. The sizing and service life requirements of the powertrains in buses and heavy working machinery are a key development area for electric vehicles, requiring familiarity with use and loading profiles in various customer segments: the working machinery sector – the bus sector; working machinery manufacturers – heavy vehicle manufacturers; working machine operators – public transport operators. Fields of application with the most potential from the perspective of the Finnish electric vehicle cluster can be covered with the help of the ECV project entity. For the eBus prototype, benchmarking is carried out by driving the pre-commercial buses in the internal bus traffic of Espoo. eBus makes use of certain functions that intersect the entire ECV entity, such as battery testing and modelling (eSTORAGE2). Regarding the battery used in the prototype bus, eBus tests the battery as part of the vehicle (including charging technology, powertrain, dissipation, control), whereas work package eStorage2 characterises batteries in more detail (including testing for certification, work cycles, condition testing, temperature management). Through the ECV project entity, manufacturers of components and subsystems can obtain experience and have their products tested in both bus and working machine environments.
Interfaces with other projects and internationality
The eBus work package is linked to the TransEco research programme on renewable energy sources and saving energy in traffic. Regarding transport system research and the charging infrastructure of electric vehicles, eBus cooperates with the Eco Urban Living project. The testing ebus prototype that will be built as a range-extender type vehicle also enables the use of a fuel cell as an auxiliary power source. Within the framework of IEA cooperation, VTT is currently implementing an extensive joint project, “Fuel and Technology Alternatives for Buses”, comprising three research agreements (Advanced Motor Fuels, Bioenergy, Hybrid and Electric Vehicles). The publishable results of the eBus work package will also be reported to the Hybrid and Electric Vehicles research agreement as well as the new “Electric Vehicle Initiative EVI”, launched by the IEA, which collects data on the electric car demonstrations held in various cities, among others.
Veolia Transport is a global public transport player that has influence with car manufacturers. The eBus work package is considered a significant research platform for electric buses by the whole Veolia Transdev Group. The data acquired through the eBus project serve the future electric mobility of the entire Group. This applies to public transport, but also to the refuse collection vehicles of the Veolia Waste Management division. With regard to Veolia Transport Finland, the project opens new opportunities, for example in operating the ring rail line and metro with electric vehicles. The project additionally develops electric buses suitable for northern conditions in cooperation with international car manufacturers, simultaneously providing Finnish component suppliers with the opportunity to test their products and demonstrate their functionality in a bus environment.
In eBus, Veolia Transport Finland works closely with the Veolia Environnement Research&Innovation (VERI) public transport division, enabling Veolia to coordinate the electric bus research conducted in other countries and disseminate the results of that research to the Finnish eBus project and ECV. Approximately 850 Veolia experts work with the development and innovation projects of VERI, testing technologies and systems and implementing them in business operations. The public transport division of VERI takes part in international EU projects such as the EBSF (European Bus System of the Future / www.ebsf.eu), HCV (Hybrid Commercial Vehicle) and WATT (Wireless Alternative Trolley Technology). Of these, EBSF specifically studies various high-technology public transport solutions for European cities.
