To achieve national climate protection goals, the decarbonisation of the transport sector is of primordial importance. However, the development of electromobility is still slowed down by high investment costs on one side and missing suitability for daily usage on the other. By means of wireless power transfer (WPT) through inductive coupling, the user comfort during the charging process can be increased significantly which leads to a wider adoption of electric vehicles (EV). Unfortunately, the contactless charging technology is still at an early stage of market maturity for domestic application. As a consequence, it cannot compensate the elevated capital costs by its additional benefits alone: On the one hand, comfort gain does not represent an economically determinable benefit and on the other, revenues from power factor correction are irrelevant for domestic usage. All the same, the additional investment costs for inductive charging infrastructure can be amortised when taking fully advantage of the EV flexibility and the prosumer’s local power generation. The present paper1 therefore aims to identify necessary conditions for long-term profitability of residential prosumers with inductive EV-charging infrastructure by means of advanced energy simulations in Matlab/Simulink R . Primary purpose of this study is a comprehensive presentation to what extend wireless EV charging in home application can already be cost-effective in order to further promote electromobility.     «
