Opportunity charging for public transportation: opportunities and challenges

In this paper, a focus on the opportunity charging for public transportation is made. In particular, the possibility of using a wireless charging system for the urban bus fleets is analyzed. A practical case study is presented. As a result, it is demonstrated how the use of the presented recharging concept contributes significantly to reducing the size, thus the cost of the on-board transport vehicles storage and distributing the power demand over the time, avoiding main grid overloads and optimizing the use of renewable energy sources.
