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

The BObby 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:


Test event by the Bobby Sharing Team

The Bobby Sharing Team organized a test event on 29.10.2019 for all students and employees of the University of Bochum.
