Rising earth temperature and increasing greenhouse gas emission is largely caused by burning fossil fuels. Next to personal vehicle use, public transportation is also having a significant role. Therefore, the electrification of the bus lines is on many countries’ and cities’ agenda. Today, electric buses and trolleys having several drawbacks what needs to be solved. Thanks to the technical development, new technologies are available to substitute the conventional practices with more effective solutions. This paper focuses on the on-the-road charging technologies what can help to reduce the size of the battery and allows to increase the travel range with the support of free mobility. The paper presents a case study for Szeged, Hungary, where self-propelled trolleybus technology is examined. Self-propelled technology allows the batteries to be charged until it is connected to the overhead line. The extra energy can be stored and used again on road section without charging opportunities. Since Budapest, the capital of Hungary, moved towards the usage of electric buses the study also analyze the potential and impact of the replacing a frequent bus line with electric buses with the support of inductive charging technology.
