System esp. charge part for accumulator for inductive transmission of electric power

摘要

The system, esp. a charging part for an accumulator, for the inductive transmission of electric power, with a primary coil (8) and a secondary coil (9), which are arranged or arrangeable adjacent to each other. A ferromagnetic ring (10) is arranged surrounding the primary coil (8) and/or a metallic plate (11) is provided between the primary coil and the housing base (4). The ring (10) is made of ferrite or iron powder. The plate (11) is arranged approximately at right angles to the axis of the primary coil (8).
