DEVICE FOR THE INDUCTIVE TRANSFER OF ELECTRIC ENERGY
First Claim
1. Device for inductive transfer of electric energy from a stationary unit with a current supply device and a primary inductance connected thereto, to a vehicle with a secondary inductance, standing adjacent to the stationary unit wherein the vehicle has an emitting device connected to the secondary inductance and set up for the supply of a data signal to the secondary inductance, and the stationary unit has a capturing device, connected to the primary inductance and set up to capture a data signal from the primary inductance, and wherein the current supply device can be activated by the capturing device, as a function of the content of the captured data signal, for the energizing of the primary inductance.

Abstract
A device for the inductive transfer of electric energy from a stationary unit having a current supply device and a primary inductance connected thereto, to a vehicle which is adjacent to the stationary unit and has a secondary inductance. The vehicle has an emitter device for sending a data signal in the secondary inductance and the stationary unit includes a capturing device for capturing a data signal emitted by the primary inductance. The current supply device is activated by the capturing device in accordance with the content of the captured data signal for injecting the primary inductance. The emitting device includes a memory with a vehicle-specific code and the data signal which it produces contains the code. The capturing device includes a memory with an authorisation code and a comparison device such that the activation of the current supply device is triggered only if the comparison device identifies the authorisation code in the captured data signal.
