The research on the electric bus(E-Bus) with replaceable battery is introduced in this study. Currently, the spread of electric vehicle(EV) is moving rather slowly than expected due to various reasons. One of the major stumbling block is a lack of charging infrastructure to support the easy recharging of the battery. In an effort to promote the wider use of EV for greener environment, many legislative efforts are being conducted. Recently, EV application to public transportation attracts major attention since the bus routes are known for each course and therefore, the electric powertrain and the energy storage system(ESS) for EV can be optimized to its maximum efficiency. However, even under this favorable condition of the public transportation, a major deficiency of EV such as a long recharging time still exists. In order to address this problem, an E-Bus with a replaceable battery system is being studied along with a battery change infrastructure. Number of scenarios have been evaluated and one of the recommended system is being discussed in the paper. An E-Bus with a quick battery change module, named as Quick Top Pick-up(QTP) is converted from an existing compressed natural gas (CNG) bus. The QTP module for the battery replacement is mounted on top of the roof panel replacing the CNG tank which is no longer in use. This paper reports the preliminary results from the conceptual design stage of the E-Bus concept with a replaceable battery system, named as QTP E-Bus, along with the battery change infrastructure, named as Quick Changing Machine (QCM). Future direction and works for the implementation of the QTP E-Bus is also presented.
