Description

The disclosure relates to a charging station for providing electrical energy for an electrically operable vehicle of a user via a charging cable.

Charging columns are typically used for charging an electrical energy store in an electrically operable vehicle, which can be plugged via a charging cable with the electrically operable vehicle. In order to realize an energy flow from the charging station to the electrically operable vehicle, an authorization of the user of the electrically operable vehicle to obtain electrical energy can be carried out at the charging station by transmitting an authorization information to the charging station.

The authorization information can be stored on a portable information carrier, in particular a chip card, and can be read out by an authorization interface of the charging station. This authorization interface is typically a component of a user interface, which is arranged at a distance from a charging interface, in particular with respect to a charging socket or a charging plug of the charging station. However, this arrangement has the disadvantage that it may be necessary for a reference of electrical energy from the charging station that the user interacts with both the user interface and the charging interface. In particular, authorization may first be performed at the user interface to effect release of the charging station for subsequent electrical connection to the electrically powered vehicle.

Furthermore, a separate embodiment of the user interface and the charging interface can increase the production cost of the charging station in a disadvantageous manner. It may be necessary for the user to perform the authorization on the user interface and to insert a charging plug into the electrically operable vehicle or the charging station. These two actions have the disadvantage that they can be carried out spatially separated, so that the use of the charging station may require an increased need for action of the user.

It is the object of the subject matter of the present disclosure to provide an improved charging station for more efficiently providing electrical power to an electrically operable vehicle. This object is solved by the features of the independent claim. Advantageous embodiments of the disclosure are the subject of the dependent claims, the description and the accompanying drawings.

The charging connector can be connected by the user with the electrically driven vehicle via a charging cable, wherein on the charging connector, an authorization of the user via the communication interface is feasible.

According to a first aspect, the disclosure relates to a charging station for providing electrical energy for an electrically operable vehicle of a user via a charging cable. The charging station comprises a charging connector in a housing, wherein the charging connector is electrically connectable to the charging cable for drawing electrical energy, and a communication interface, which is at least partially disposed in the housing and configured to wirelessly read an authorization information of the user from an information carrier. Furthermore, the charging station comprises a processor which is adapted to determine the authorization of the user for the receipt of electrical energy on the basis of the read authorization information, and a release device, which is designed, the charging station with a determined authorization of the user for the receipt of electrical energy by the electrically authorized user.

The charging station can be configured to transport electrical energy from a supply network connection to an energy store, preferably an electrical energy store, in the electrically operable vehicle. Configuration parameters, in particular a current intensity, voltage and / or frequency of an electric charging current, which flows from the charging station to the electrically operable vehicle, may be included in the authorization information. Furthermore, in the authorization information, a charging current characteristic can be defined, which can determine the aforementioned parameters of the electric charging current or its time profile over the duration of a charging process in which the electric charging current flows from the charging station to the electrically operable vehicle.

The communication interface may be, for example, a radio frequency identification (RFID) interface according to the standard ISO / IEC 14443 or ISO / IEC 18000-3 his.

A pivotable design of the cover has the advantage that the cover can be firmly connected to the charging connector and removal of the cover can be prevented. Furthermore, by the pivoting mechanism a permanently constant alignment of the flap can be realized to the charging connector, so that a manual alignment of the flap to the charging connector may not be necessary. The cover can provide protection according to one of the protection types IP11 to IP69K, including protection against contact, ingress of water and / or dust, and / or thermal insulation.

In one embodiment, the release device includes a locking actuator for locking or unlocking the cover, and the locking actuator is configured to unlock the cover to release the charging connector for connection to the charging cable.

The locking actuator for unlocking or locking the cover can be realized by an electromechanical closure, wherein a mechanical locking or unlocking can be triggered by an electromagnetic signal. The unlocking of the cover may signal to the user that the charging station has authorized the user based on the authorization information for the receipt of electrical energy via the charging station. The charging connector may be a charging socket or a charging plug, which can be covered by the cover and / or locked in order to realize a connection to the charging cable with the cover open and unlocked. The locking actuator may be configured to unlock or lock the cover in the event of a power supply failure of the locking actuator, in order to prevent the charging cable from disconnecting from the charging connector in the event of a power failure of the charging station.

In one embodiment, the release device has a locking bolt, which is movable by the locking actuator for locking or unlocking the cover, wherein the locking pin engages for locking the cover in a locking receptacle of the cover.

Thereby, the advantage is achieved that the cover can be mechanically locked and / or unlocked and in the locked or unlocked state, an electromagnetic signal or a force of the Verriegelungsaktuators may not be necessary to maintain the locked and / or unlocked state. In particular, unlocking and / or locking can not be triggered by an interruption of the power supply of the Verriegelungsaktuators. The Verriegelungsaktuator can be arranged in a housing of the charging connector or and are supplied via the charging connector, respectively via a control line of the charging connector with electrical energy. Furthermore, an electrical signal for locking and / or unlocking the cover can be sent via the control line to the Verriegelungsaktuator.

The locking bolt may in particular be designed to maintain a locking of the charging connector with the cover under the action of mechanical force. The locking bolt may be made of a metal and / or of a plastic, in particular of the same material be made of the cover or the housing of the charging connector.

Further, the locking bolt may engage a receptacle in the cover and / or the housing of the charging connector to realize a locked connection between the housing of the charging connector and the cover. This locked connection can in particular be a non-positive and / or positive connection.

The engagement of the locking bolt in the receptacle can be realized by a displacement of the locking bolt. The necessary for unlocking and / or locking displacement distance can be sufficiently large to prevent unlocking and / or locking by vibration or other accidental force.

In one embodiment, the cover is spring loaded by a spring and, upon withdrawal of the charging cable from the charging connector, closes the cover.

As a result, the advantage is achieved that a separate closing of the cover after deduction of the charging cable, in particular a manual closing by the user may not be necessary. This can increase the efficiency and ease of use of connecting the charging cable to the charging station and reducing the likelihood of operator error, as closing the charging connector through the cover may not require user interaction.

The spring can exert increasing, decreasing or constant restoring force with an increasing opening angle between the loading connector and the cover. If the restoring force is maximum at small opening angles, for example, a sealing closure between the loading connector and the cover can be realized and, with decreasing restoring force at larger opening angles, the force to be applied after initial opening by a user can be advantageously reduced. If the restoring force is maximum at large opening angles, the acceleration of the closing movement of the cover in the direction of the charging connector can advantageously be increased, so that the time required for the closing operation can be reduced. If the restoring force is independent of the opening angle, the cover can advantageously be combined with a damping in order to realize a slow and / or uniform closing of the cover. This can in particular prevent the likelihood of pinching objects, in particular the charging cable or fingers of the user.

The spring may cause closure or opening of the cover. If the spring is designed to open the cover, after unlocking the cover by the Verriegelungsaktuator the cover can be opened automatically and the charging connector for connecting the charging cables are released for the user. This can advantageously account for a manual opening of the cover by the user. Closing the cover by the user can signal the completion of the energy purchase by the user to the charging station so that the charging station can be used for a new charging process, in particular with another user.

In one embodiment, the cover has an electrical contact, which contacts a different electrical contact of the housing when the cover is closed, wherein the release device is designed to lock the cover, in particular by means of a Verriegelungsaktuators, if the electrical contact electrically contacts the further electrical contact ,

As a result, the advantage is achieved that a final position of the cover can be monitored and / or detected on the charging connector. A locking or unlocking of the cover can be realized, for example, in response to the detection of the position of the cover. In particular, a triggering of the locking or unlocking can be prevented by the Verriegelungsaktuator, if the cover is not in a necessary position for locking or unlocking.

Advantageously, the information carrier is a smartphone or a chip card with an NFC interface, wherein the smartphone can replace an additional chip card.

In one embodiment, the communication interface is designed to generate an electromagnetic field for activating the information carrier for reading out the authorization information.

As a result, the advantage is achieved that the information carrier can have an active and an inactive operating state. The active operating state of the information carrier can be characterized by an energy supply of the information carrier via an existing communication connection or an energy source integrated into the information carrier and the possibility of reading out the authorization information from the information carrier. In the passive operating state of the information carrier, the authorization information is obtained and can be read out of the information carrier by a change to the active operating state. The passive operating state can differ from the active operating state by a lower consumption of electrical energy, in particular the information carrier consumes no electrical energy in the passive operating state. Likewise, the communication interface of the charging station can have an active operating state and a passive operating state with a lower consumption of electrical energy compared to the active operating state.

Activation of the information carrier via the electromagnetic field can realize a non-contact activation of the information carrier, wherein the electromagnetic field can at least partially enforce the information carrier.
