APPLIKATION AV CYKELLADDNING OMBORD PÅ JÄRNVÄGSFORDON : Konceptutveckling av elcykelladdning ombord på Öresundståget Contessa X31 i samarbete med Bombardier Transportation

Sammanfattning: There is a great need to reduce the use of fossil-fueled road transport. In order to encourage the use of public transport, opportunities for the application of electrical charging stations for e-bikes aboard railway vehicles were analyzed. A theoretical concept was developed for the introduction of electrical charging stations aboard railway vehicles, with Contessa - Oeresund Train Unit X31 as the subject of study. The design was based on a set of required management characteristics, which included any requirements from the vehicle owner, traveler and society (such as improved environment, public transport and health of the citizens). The study was based on the current standards, requirements and safety regulations for railway vehicles operating within the European Union. Upon completion of the study, one was able to establish that the potential exists for introducing the concept aboard the subject of study, as well as for other railway vehicles. The charging station consisted of a group of three power supplies and a sizing was performed for two such groups, to adapt as needed.The result indicates that fast charging modes have the greatest functionality for users with shorter travel time on board the train, such as commuters. At the present time, it is not possible to implement a fast charging mode as a standard feature for all e-bikes, as no standardized fast charger fits all e-bikes, independent of the manufacturer. Fast charging modes cannot be implemented for normally charged electric bicycles based on functionality, battery wear and fire risk. Furthermore, the study shows that large reductions in greenhousegas emissions can be achieved using electric bicycles in combination with communal trains, by effectively replacing car trips.
