SYSTEM FOR CONTACTLESS TRANSFER OF ENERGY AND DATA AND VEHICLE WITH SUCH A SYSTEM
First Claim
1. A system for the contactless transfer of energy and data,comprising a transfer path with at least one primary coil, connected by way of a primary line to a primary control unit, and at least one secondary coil connected by way of a secondary line to a secondary control unit,wherein the primary control unit is configured to lead data-modulated first alternating-voltage signals of a first frequency range into the primary coil, andwherein the secondary control unit is configured to receive the first alternating-voltage signals of the first frequency range from the secondary coil, and to demodulate the modulated-on data;
- a feed-in line connected to the primary line,an activation line connected to the secondary line, anda first filter arranged between the activation line and an activation connection,wherein the first filter is permeable to second alternating-voltage signals of a second frequency range while blocking the first alternating-voltage signals of the first frequency range.

Abstract
A system for the contactless transfer of energy and data includes a transfer path with a primary coil and with a secondary coil. The primary control unit is designed to lead data-modulated first alternating-voltage signals of a first frequency range into the primary coil. The secondary control unit is designed to receive the first alternating-voltage signals of the first frequency range from the secondary coil, and to demodulate the modulated-on data. The system further includes a feed-in line for feeding a second alternating-voltage signal of a second frequency range to a primary line leading to a primary coil and an activation line that is connected to a secondary line that is connected to the secondary coil. A first filter filters the second alternating-voltage signal from the secondary line and provides the signal to an activation connection.
