System For Contactless Power Transfer
First Claim
1. A system for contactless power transfer between a first vehicle part and at least one collector that can be variably positioned relative to the first vehicle part in a passenger cabin of a vehicle, comprising:
- a first control unit with a voltage input and at least one primary voltage output,a plurality of primary windings configured to be positioned on the first vehicle part, the plurality of primary windings further configured to be connected to the primary voltage output of the first control unit,a second control unit with a secondary voltage input,a secondary winding, arranged on the collector and configured to be connected to the secondary voltage input of the second control unit,wherein the collector is configured to be positioned in such a manner relative to the primary windings that between the secondary winding and a primary winding a transducer is formed for transferring a voltage from the primary winding to the secondary winding,wherein the collector comprises a voltage provision unit with a connection for supplying external loads, andwherein the first control unit is connected to an operating-mode switching device that is configured, during operation of the vehicle, to interrupt the connection between the primary windings (and the primary voltage output forming a transducer with a secondary winding of the collector.

Abstract
A system for inductive contactless power transfer between a first vehicle part and at least one collector that can be variably positioned relative to the first vehicle part in a passenger cabin of a vehicle includes primary windings (P1-PN) that with secondary windings (S1, S2) on collectors or second vehicle parts can form a transducer. Depending on operating-mode switching of the vehicle, the operation of collectors is prevented, which collectors for the purpose of providing electrical power for operating external cleaning or maintenance devices are brought into the vehicle. Because of the expansion of the function of an existing contactless power and data transfer system, the system is particularly cost-effective and flexible, and in addition is of a very lightweight design.
