Title:
PLUG DEVICE FOR CONTACT-FREE INDUCTIVE ENERGY TRANSFER AND OPERATING METHOD FOR SUCH A PLUG DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/087676
Kind Code:
A3
Abstract:
The invention relates to a plug device for contact-free inductive energy transfer from a primary part (1) to a secondary part (1'), which each have at least one coil (10, 10') and are inductively connected to each other. The plug connection is characterised in that the at least one coil (10, 10') works together with at least one ferrite core (11, 11') in each case. The invention also relates to an operating method for a plug device for contact-free inductive energy transfer from a primary part (1) to a secondary part (1'). A measurement of operating factors of a primary coil (10) used for inductive energy transfer is taken at the primary part (1) and energy transfer is inhibited depending on the measured operating factors.
