Abstract

In-Motion-Charging (IMC) buses are destined to become a key player in sustainable urban transport as they combine the advantages of both trolleybuses (overhead supply mode) and e-buses (on-board battery mode). Defining the route ratio of these two modes of operation is a critical task in order to ensure that the IMC battery can complete a full trip once it is out of the charging corridor zone (i.e., out of the trolleybus operation zone). This paper offers a more correct approach to sizing the charging corridor than what is commonly found in literature, by including the effects of both the stopping and moving times of a typical IMC bus and by studying two charging schemes for the IMC bus battery charging. Errors as high as 16.4% and 17.6% were reported for the two charging schemes, respectively, when using the conventional methods found in literature for a case study using measurements of the trolleygrid city of Arnhem, the Netherlands.
