Abstract

A charging plug for an electrically driven vehicle has a feed line for electrically connecting the charging plug (10) to a charging infrastructure, power contacts and a signal contact for electrically connecting the charging plug (10) to the vehicle. A rectifier (12) is connected to the feed line and to the power contacts for converting an alternating current obtained by the feed line into a direct current that is delivered by the power contacts in a charging process. A control and protection device (14) is connected to the feed line, to the power contacts and to the signal contact for matching the charging process to the vehicle by means of the signal contact.

Claims

1. A charging plug for an electrically driven vehicle, comprising:

a feed line for electrically connecting the charging plug to a charging infrastructure;

power contacts and a signal contact for electrically connecting the charging plug to the vehicle;

a rectifier connected to the feed line and to the power contacts, for converting an alternating current that is obtained by the feed line into a direct current that is delivered by the power contacts in a charging process; and

a control and protection device connected to the feed line, to the power contacts and to the signal contact, for matching the charging process to the vehicle by means of the signal contact.

2. The charging plug of claim 1, further comprising a first module for evaluating an integral of a previous charging power.

3. The charging plug of claim 2, further comprising a second module for evaluating a coolant temperature.

4. The charging plug of claim 3, further comprising characterized by a third module for evaluating an energy throughput.

5. The charging plug of claim 4, further comprising a fourth module for detecting an outside temperature.

6. The charging plug of claim 5, further comprising a fifth module for detecting internal device temperatures.

7. The charging plug of claim 6, further comprising a sixth module for detecting and evaluating an existing power of a respective power path.

8. The charging plug of claim 7, further comprising a seventh module for detecting an existing current or voltage loading of semiconductors and transformers.

9. The charging plug of claim 8, further comprising an eighth module for outputting a power increase recommendation to a charging management system.

10. The charging plug of claim 9, further comprising a ninth module for preparing control data for the signal contact.
