Abstract

Charging cable plug 1 for electric vehicles, with a housing 2 and electrical contacts 6, arranged in the housing 2, for connection to a charging station 4. For simple identification before a charging procedure, an identification means 8 is proposed, arranged in the housing 2 and communicating with the charging station 4 via the electrical contacts 6.

Claims

1. Charging cable plug for electric vehicles, with

a housing (2),

electrical contacts (6), arranged in the housing (2), for connection to a charging station (4), and

an identification means (8) arranged in the housing (2) and communicating with the charging station (4) via the electrical contacts.

2. Charging cable plug according to claim 1, characterised in that the identification means (8) is formed such as to transfer an identification signal via the contacts (6) to the charging station (4).

3. Charging cable plug according to claim 1 or 2, characterised in that the housing (2) has a receiver (10) for a locking means (12) of the charging station (4) such that after the locking means (12) has been received, the plug is secured by form fit to the charging station (4).

4. Charging cable plug according to one of the preceding claims, characterised in that the housing (2) has a reading means (14) configured to read a user identification, and in that the reading means (14) is in operational connection with the identification means (8).

5. Charging cable plug according to claim 4, characterised in that the reading means (14) is formed for contact-free reading of a key (16) emitting a user identification.

6. Charging cable plug according to claim 4 or 5, characterised in that the reading means (14) is a transponder reading device.

7. Charging cable plug according to one of claims 4 to 6, characterised in that the reading means (14) is formed to emit a signal to the identification means (8) on receipt of the user identification.

8. Charging cable plug according to one of claims 4 to 7, characterised in that the identification means (8), on receipt of the signal from the reading means (14), transmits a release signal to the charging station (4), at least deactivating the locking means (12).

9. Charging cable plug according to claim 8, characterised in that the release signal interrupts the supply of energy through the charging station (4).

10. Charging cable plug according to one of the preceding claims, characterised in that arranged in the housing (2) is a connection identification means (18), which identifies an electrical connection of the contacts (6) to a charging station (4), wherein the connection identification means (18) activates the identification means (8) when a connection to the charging station (4) is identified.

11. Charging cable (20) with a charging cable plug according to claim 1.

12. System with a charging cable (20) according to claim 11 and a charging station (4).

13. System according to claim 12, characterised in that a key (16) emitting a user identification is provided for communication with the reading means (8).

14. System according to claim 12 or 13, characterised in that the charging station (4) has locking means (12) for locking the plug in the charging station (4) after the receipt of an identification signal from the plug.

15. System according to one of claims 12 to 14, characterised in that the charging station (4) has energy release means (26) for releasing a supply of energy to the plug on receipt of an identification signal from the plug and/or for interrupting the supply of energy on receipt of the release signal from the plug.
