Abstract

A charging plug for an electrically driven vehicle has a feed line for electrically connecting the charging plug to a charging infrastructure. The charging plug includes power contacts, a signal contact, a rectifier, and a control and protection device. The power contacts and signal contact electrically connect the charging plug to the vehicle. The rectifier 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 to the vehicle in a charging process. The control and protection device 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 charging an electrically driven vehicle, the charging plug configured to be electrically connected to a charging infrastructure via a feed line, the charging plug comprising:

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, the rectifier converts an alternating current that is provided by the feed line into a direct current that is delivered to the vehicle by the power contacts in a charging process;

a control and protection device simultaneously connected to the feed line, to the power contacts, and to the signal contact, the control and protection device configured to communicate with the vehicle via the signal contact, wherein, based on the communication with the vehicle, the control and protection device selectively controls the rectifier to match a charging process to the vehicle,

a first module for evaluating an energy throughout at the power contacts of the charging plug, wherein, based on the energy throughout, the control and protection device is configured to control the rectifier to adjust the power provided to the vehicle via the power contacts; and

a handle including an interior, wherein the rectifier and control and protection device are each disposed in the interior of the handle.

2. The charging plug of claim 1, further comprising a second module for evaluating an integral of a previous charging power, wherein, based on the evaluated integral, the control and protection device is configured to control the rectifier to adjust the power provided to the vehicle via the power contacts.

3. The charging plug of claim 2, further comprising a third module for evaluating a coolant temperature, wherein, based on the coolant temperature, the control and protection device is configured to control the rectifier to adjust the power provided to the vehicle via the power contacts.

4. The charging plug of claim 3, further comprising a fourth module for detecting a temperature outside the charging plug, wherein, based on the temperature outside the charging plug, the control and protection device is configured to control the rectifier to adjust the power provided to the vehicle via the power contacts.

5. The charging plug of claim 4, further comprising a fifth module for detecting a temperature inside the charging plug, wherein, based on the temperature inside the charging plug, the control and protection device is configured to control the rectifier to adjust the power provided to the vehicle via the power contacts.

6. The charging plug of claim 5, further comprising a sixth module for detecting and evaluating power of an electrical path within the charging plug, wherein, based on evaluated power of the electrical path, the control and protection device is configured to control the rectifier to adjust the power provided to the vehicle via the power contacts.

7. The charging plug of claim 6, further comprising a seventh module for detecting an existing current or voltage loading of semiconductors and transformers of the charging plug, wherein, based on the existing current or voltage loading of the semiconductors and transformers of the charging plug, the control and protection device is configured to control the rectifier to adjust the power provided to the vehicle via the power contacts.
