Research and development

Battery as a Service

With the Swobbee battery changing and charging station, the Bobby E-Scooter Sharing project is testing a new way of supplying LEVs (Light Electric Vehicles) with energy. The station is located at the west side of the D3 building. The station has six compartments for the batteries of the Kumpan scooter and two compartments for greenpack batteries. The station offers users of sharing services a quick and convenient way to continue their journey when the batteries are empty.

Currently the user identifies himself via a customer card on the cabinet, selects the desired battery type and then places his empty battery in a free compartment. Once this is done, a full battery can be taken out. In the future, solutions are to be developed to access the changing station with the help of an app and to implement a block chain solution for demand-based billing of energy consumption.

Funded by the FH-Basis program of the Ministry of Culture and Science of the State of Nordrhein-Westfalen.

Fill it up, please! - Battery changing and charging station

The BObby E-Scooter Sharing Team is researching in the field of "Battery as a service" to provide battery management for the e-scooters. In this context the new battery charging cabinet "Swobbee" has been delivered and installed in front of the D3 building. The empty batteries of the scooter can be exchanged with the loaded batteries from the cabinet. There are six slots for the Kumpan-battery and two slots for greenpack-batteries available for this purpose.


e-Scooter Sharing in Bochum

The e-scooters from the project study are on the road in Bochum. The video shows the 1954 Ri from e-bility in Remagen and the N-Series from Niu. Further information can be found on the project website:
