Optimization of ebike (pedelec) sharing systems
Summary:
A German university of applied science and arts conducts a project on electric two-wheelers for recreation and tourism that deals with the integration of an ebike sharing system in cities. The university is mainly in charge of the technical and social-science based evaluation of the sharing system. The project team offers its know-how, methodology and technical data to companies and organizations interested in technical cooperation or joint research projects on the topic.
Description:
The project started in May 2013 within the German federal government program on electro mobility. Thereby, two ebike sharing system have been built:
1. In a German city a sharing system was launched on the 01.09.2015 with a total of 52 ebikes and 3 stations. Besides the regular ebikes it is also possible to rent electric cargobikes. The rental is free of charge until the end of the project (30.06.2016).
2. At the university a sharing system was launched on the 07.09.2015 with a total of 11 ebikes and 2 stations. The rental is for employees and students only and is also free of charge.

As a partner of the project the German university is mainly in charge of the technical and social-science based evaluation of the ebikes and the sharing system. Since the maintenance costs for an ebike is higher due to the additional electronic parts than for a regular bike, it is reasonable to adjust the dimensioning of the ebikes to the driving behavior of the customers. As a result, failure rates and maintenance costs can be reduced. For this purpose, the ebikes are being equipped with data loggers which record driving relevant data (e.g. GPS data, velocity, motor current) during a trip.

The university already developed a method to generate user specific driving cycles in order to represent the average driving behavior of the customers. With the driving cycles and the other data it is possible to examine different loads of the ebikes in different situation. Thereby, conclusions about occurred damages can be drawn. As a result, recommendations can be derived in order to optimize the dimensioning of the ebikes. For the examination two test benches are available at the institute. With the first one it is possible to analyze different ebikes regarding their energy demand under consideration of different influencing factors and velocity profiles. The second test bench is for the analysis of different ebike motors (hub motors as well as middle motors).

Technical cooperation and joint research projects are offered to academia, industrial partners and other organisations / institutions.

Advantages and Innovations:
The research work of the university has several advantages and innovations:
- With the comprehensive data collection it is possible to analyze many different driving situations. In addition to that, the cause of damages can be identified more quickly because of the different characteristic data that are being recorded.
- Based on the recorded data user specific driving cycles are being developed. Therefore, different loads can be simulated and damages can be reconstructed with the ebike test benches of the university.
- The achieved results are being used to develop a maintenance concept. Thereby, it will be determined at what point which part has to be maintained.
The listed points are relevant for an optimized dimensioning of the ebikes within the sharing system. In this way the availability of the ebikes will be increased permanently and the maintenance costs will be reduced to a minimum. This leads to an improved acceptance of the sharing system and at the same time it improves the economic efficiency.
