Design and Dimensioning of a Highly Efficient 22 kW Bidirectional Inductive Charger for E-Mobility

摘要

As part of the project Gemeinschaftlich-e-Mobilitat: Fahrzeuge, Daten und Infrastruktur GeMo, we at Fraunhofer ISE are developing a stationary 22 kW bidirectional inductive battery charger for use in electric vehicles. This paper outlines the optimal dimensioning of the coils and overall topology of the charging system. The focus is on high power and efficiency over as large as possible variation in the vertical and horizontal displacements of the two coils.
