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 ### Claim 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 that electrically connect 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; and 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 selects the type of charging process to the vehicle according to signals on the signal contact. ### Claim 2 (depends on 1) The charging plug of claim 1, further comprising a first module that evaluates an integral of a previous charging power. ### Claim 3 (depends on 2) The charging plug of claim 2, further comprising a second module that evaluates a coolant temperature. ### Claim 4 (depends on 3) The charging plug of claim 3, further comprising characterized by a third module that evaluates an energy throughput of the charging plug. ### Claim 5 (depends on 4) The charging plug of claim 4, further comprising a fourth module that detects a temperature outside the charging plug. ### Claim 6 (depends on 5) The charging plug of claim 5, further comprising a fifth module that detects a temperature inside the charging plug. ### Claim 7 (depends on 6) The charging plug of claim 6, further comprising a sixth module that detects and evaluates power of an electrical path within the charging plug. ### Claim 8 (depends on 7) The charging plug of claim 7, further comprising a seventh module that detects an existing current or voltage loading of semiconductors and transformers of the charging plug. ### Claim 9 (depends on 8) The charging plug of claim 8, further comprising an eighth module that outputs a power increase recommendation to a charging management system of the charging infrastructure. ### Claim 10 (depends on 9) The charging plug of claim 9, further comprising a ninth module that prepares control data for the signal contact.
