Cloud-based Battery Replacement Scheme for Smart Electric Bus System

This paper proposes a Smart Electric Bus (e-Bus) Battery SUbstitution Scheme called SBUS in a cloud-based e-Bus system for the efficient battery replacement during e-Bus services. A smart e-Bus system using cloud-based management is considered as an alternative public transportation system. The battery of an e-Bus often needs to replaced, which can be one of the reasons for vehicle traffic congestion. When the battery of an e-Bus was not enough to run itself on its service route, it needs to replace its battery during the running. By this reason, road traffic congestion can be caused by this routine battery exchange. In order to solve this problem, SBUS is proposed to reduce road traffic congestion. To our knowledge, this paper presents the first attempt to investigate how to effectively assign an appropriate e-Bus station for battery replacement e-Bus station for battery replacement to each e-Bus to reduce road traffic congestion. As a result, the proposed scheme can assign an appropriate e-Bus station for battery replacement to each e-Bus to reduce road traffic congestion. To show the effectiveness of the proposed SBUS, we compare it with baseline schemes through simulation. The results of the experiment show that SBUS is more efficient than the baseline schemes in terms of the shorter average waiting time for battery replacement and the shorter end-to-end travel delay for e-Bus services.
