An Integrated Approach for Dynamic Charging of Electric Vehicles by Wireless Power Transfer - Lessons Learned from Real-Life Implementation

摘要

The aim of this paper is to introduce a complete fast dynamic inductive charging infrastructure from the back-office system (EVudmanagement system) up to the Electric Vehicle (EV) (inductive power transfer module, positioning mechanism, electric vehicleudmodifications) and the EV user (User interface). Moreover, in order to assess the impact of the additional demand of inductive charging onudthe grid operation, an estimation of the 24-hour power profile of dynamic inductive charging is presented considering, apart from the roadudtraffic, the probability of the need for fast charging, as well as the specifications of the proposed solution. In addition, an energyudmanagement system is presented enabling the management of the operation of the inductive charging infrastructure, the interaction withudthe EV users and the provision of demand response services to different stakeholders. The proposed dynamic inductive charging approachudhas been demonstrated within a real urban environment in order to provide useful insights regarding the experience gained from audreal-field trial. The relevant practical conclusions are also discussed in this paper. Finally, a cost/benefit analysis, according to theudDiscounted Cash Flow (DCF) principles, is performed in order to assess the economic viability of the proposed solution.
