- a device for controlling a charging connection cover of an electric vehicle with a detector device and a control device.
- the detector device is designed to detect a charging station for charging the electric vehicle in a predetermined spatial area around the electric vehicle.
- the controller is configured to open the charging port cover of the electric vehicle.
- the controller is designed to open the charging port cover of the electric vehicle when a charging station for charging the electric vehicle has been detected in the predetermined area around the electric vehicle.

- the present invention is based on the finding that the charging connection of an electric vehicle is usually covered by a charging connection cover, or charging flap for short. To charge the electrical energy store of the electric vehicle, this cover must therefore first be opened before the electric vehicle can be connected to an electrical energy source such as a charging station. The opening or closing of this charging port cover requires additional actions from the user. In the case of automatic charging port covers in particular, which can be opened and closed by means of an actuator such as an electric motor, the user may first have to actuate a switch in the vehicle interior that initiates the automatic opening of the charging port cover. In this way, the connection of the electric vehicle to an external energy source can be relatively complex.
- the user automatically gains access to the charging port of the electric vehicle when near a detected charging station.
- Opening or releasing the charging port cover can include both unlocking the charging port cover and automatically opening the charging port cover by means of a suitable actuator. The user can thus simply get out of the vehicle and then immediately plug a cable with a suitable plug into the charging connection of the electric vehicle. An additional actuation of a switching element, for example in the interior of the vehicle before getting out, is not necessary.
- the automatic opening or release of the charging port cover can also be linked to other conditions. For example, after detecting a suitable charging station, the charging port cover can only be opened when the Vehicle is in a suitable operating mode, for example in the park position. Furthermore, it is also possible, for example, to open the charging connection cover when the vehicle driver opens a door of the vehicle, for example in order to get out. For this purpose, either only the driver's door can be considered, or alternatively any door of the vehicle, in order to enable a passenger to connect the electric vehicle to the charging station, for example.
- the charging connection cover can only be opened if a charging station has been previously detected, which is also suitable for charging the corresponding electric vehicle. Any suitable parameters can be considered for this. For example, it can be checked whether the charging station is suitable for providing the electrical energy in the type of voltage (AC or DC), voltage level and/or power required for charging the electric vehicle. Furthermore, it can also be checked whether the detected charging station is a charging station for which the vehicle driver or the vehicle has authorization to charge at the corresponding charging station. Of course, any other parameters that are previously checked before opening the charging port cover can also be considered.
- the charging connection cover can be opened automatically by means of a suitable actuator.
- a suitable actuator can be an electric motor, for example, which controls a mechanism of the charging connection cover, if necessary by means of a corresponding gear.
- any other suitable actuators such as electromagnetic actuators or actuators using a fault memory, are of course also possible.

Communication with such a remote server can take place via any suitable communication channel, for example a cellular connection or the like.
- the detector device can include a radio interface.
- the radio interface can be designed, for example, to detect a charging station for charging the electric vehicle using wireless communication. Any suitable wireless communication is possible for this purpose.
- wireless communication can take place using a WLAN (WiFi), Bluetooth, ZigBee, near field communication (NFC) or mobile radio.
- the charging stations can emit radio signals with a specified (restricted) power.
- the detector device can detect a charging station as soon as such a radio signal has been received via the radio interface.
- a charging station can be detected as soon as a corresponding radio signal with at least one predetermined signal level has been received.
- the charging stations may specify the position of the charging station in the radio signals and for the detector device to specify this compares the specified position of the charging station with the current position of the electric vehicle to determine whether the electric vehicle is close to the charging station.
- the detector device may specify this compares the specified position of the charging station with the current position of the electric vehicle to determine whether the electric vehicle is close to the charging station.
- any other suitable methods are also possible to detect a suitable charging station in the vicinity of the electric vehicle by means of wireless communication.
- the detector device includes at least one surroundings sensor.
- the at least one environment sensor is designed to detect a charging station for charging the electric vehicle in the environment of the electric vehicle.
- the environment sensor can be an optical camera, for example.

- the detector device can then analyze this captured image data in order to possibly detect a charging station in the vicinity of the electric vehicle in the image data.
- Any suitable image processing methods in particular image processing methods based on neural networks or the like, are possible for this purpose.
- ultrasonic sensors, radar sensors, LIDAR sensors or the like are also possible as environment sensors. Accordingly, a signature of these sensors can also be evaluated in order to detect characteristic features in the sensor data, which indicate a charging station in the vicinity of the electric vehicle.
- the device for controlling the charging connection cover includes a release device.
- the release device is designed to activate and/or authenticate a charging process with the detected charging station.
- the charging station can be in a deactivated state or in a standby mode by default. Accordingly, the release device can automatically activate the charging station as soon as the electric vehicle approaches the charging station and the corresponding charging station has been detected in the vicinity of the electric vehicle.
- the release device can also exchange authentication data with the charging station, for example. In this way, for example, the charging process can only be released after successful authentication with the charging station has taken place.
- the authentication can include the transmission of any suitable authentication information. For example, a vehicle identification can be transmitted to the charging station.
- the vehicle can be identified, for example, using a previously stored chassis number, a media access control address (MAC address) of a communication interface, or the like.

- the user-specific configuration data can also include a current temperature of the electrical energy store in the electric vehicle. This can, for example, provide an indication of whether the charging power is limited due to the temperature of the energy store, or whether the energy store may have to be cooled or heated at the beginning of the charging process.
- the user-specific or vehicle-specific data can also include any other suitable data about the vehicle or the user's wishes.
