Abstract

Methods and devices that establish communication between a first station and a second station are provided. To this end, an identifier, which identifies the first station and the second station as communication partners for communication, is transmitted between the first and second stations on a first partial connection. After receiving said identifier, communication is started between the first and second stations via a communication connection, wherein the transmission of the identifier via the first partial connection and the communication connection are based on different physical connections. The methods and systems can be used for loading or unloading processes of electrical vehicles, such as autonomous systems in the hospital field, or for vehicles for personal transportation. The methods and systems may provide reliable and cost-effective communication between the first and second stations.

Claims

1. A method for establishing communication between a first station and a second station is connected directly to the first station via a charging connection for charging or discharging a memory unit of the second station, comprising:

transmitting at least one identifier via a first partial connection of the charging connection, wherein the identifier identifies the first station and the second station as communication partners for communication, and

after receiving said identifier, starting the communication using the identifier via a communication connection for performing the communication between the first station and the second station,

wherein the first partial connection and the communication connection are different physical connections.

2. The method of claim 1, wherein the identifier is transmitted from the first station to the second station.

3. The method of claim 1, wherein the identifier is transmitted from the second station to the first station.

4. The method of claim 1, wherein the identifier is created in the form of an address of at least one of the first station and the second station.

5. The method of claim 4, wherein the address is created in the form of an IP address, a service set identification, a MAC address, or a network segment address.

6. The method of claim 1, wherein the identifier is transmitted after the establishment of the charging connection.

7. The method of claim 1, wherein the first partial connection of the charging connection is established on the basis of a pulse-width modulated signal, a frequency-modulated signal, an amplitude-modulated signal, or a phase-shift-key modulated signal.

8. The method of claim 1, wherein the communication connection is established on the basis of a wireless connection or a wire-bound connection.

9. The method of claim 1, wherein the communication connection is created on the basis of at least one second partial connection of the charging connection, wherein the at least one second partial connection is embodied to transmit energy for charging or discharging the memory unit.

10. The method of claim 1, wherein the identifier is transmitted in encoded form.

11. The method of claim 1, wherein key information is transmitted via the first partial connection.

12. A transmission system for establishing communication with a first station and with a second station connected directly to the first station via a charging connection to charge or discharge a memory unit of the second station, comprising

a first partial connection of the charging connection for configured to transmit at least one identifier, wherein the identifier identifies the first station and the second station as communication partners for communication, and

a communication connection configured to perform the communication between the first station and the second station, wherein the communication can be started after receiving the identifier by the first station or by the second station using the identifier, and

wherein the first partial connection and the communication connection are different physical connections.

13. The transmission system of claim 12, wherein the first partial connection of the charging connection is established on the basis of a pulse-width modulated signal, a frequency-modulated signal, an amplitude-modulated signal, or a phase-shift-key modulated signal.

14. A first station for establishing communication between the first station and a second station, wherein the first station is connected directly to the second station via a charging connection for charging or discharging a memory unit of the second station, comprising:

means for transmitting at least one identifier via a first partial connection of the charging connection, wherein the identifier identifies the first station and the second station as communication partners for communication, and

means for performing the communication between the first station and the second station via a communication connection, wherein the communication can be started after receiving the identifier by the first station or by the second station using the identifier, and

wherein the first partial connection and the communication connection are different physical connections.

15. The first station of claim 14, wherein the first partial connection of the charging connection is established on the basis of a pulse-width modulated signal, a frequency-modulated signal, an amplitude-modulated signal, or a phase-shift-key modulated signal.
