Description

The present invention relates to a charging socket for an electric vehicle, as well as street lighting and a wall box with such a charging socket.

It is currently common practice to include charging controllers for controlling a charging process of an electric vehicle in wall boxes or other housings, the charging controller being assembled from individual components. The wiring of the charging controller with the charging contacts of the assigned charging socket is usually done by manual crimping and is therefore prone to errors. If there are errors in the structure and / or the wiring, commissioning will be significantly delayed.

Against this background, the present invention is based on the technical problem of specifying a charging socket for charging an electric vehicle, street lighting and a wall box which do not have the disadvantages described above or at least to a lesser extent, and in particular a quick and error-free connection between charging contacts and a Enable charge control.

The technical problem described above is solved by a charging socket according to claim 1, street lighting according to claim 9 and a wall box according to claim 10. Further embodiments of the invention emerge from the dependent claims and the following description.

According to a first aspect, the invention relates to a charging socket for an electric vehicle, with a first housing, a plurality of charging contacts, such as power contacts, signal contacts or the like, being accommodated in the first housing, with a second housing in which a charging controller is accommodated, which is set up to control a charging process, the charging contacts of an interface formed on the first housing being contacted, and a plug connection being formed between the charging controller and the interface. The plug connection enables an error-free connection of the charging controller with the charging contacts of the charging socket. In this way, the charging controller can be quickly connected to the charging contacts.

According to a further embodiment of the charging socket, it is provided that the charging contacts are at least partially enclosed by a wall of the first housing, the second housing being arranged on an outer side of the wall facing away from the charging contacts. Accordingly, the first housing and the second housing can be directly connected to one another, so that a compact integration of the charging controller into the charging socket is made possible.

Alternatively or in addition, it can be provided that the second housing is detachably connected to the first housing. For example, a positive and / or non-positive connection, such as a screw connection, a clip connection or the like, can be formed between the first housing and the second housing.

The first housing and the second housing can therefore be provided separately from one another in one assembly process with the components received therein and can be connected to one another by plugging them together.

It can be provided that the plug connection has a mechanical coding that prevents incorrect assembly or incorrect plugging together in the area of the interface. For example, the interface can be surrounded by an asymmetrical housing wall which defines an orientation of the first housing with respect to the second housing in conjunction with a complementarily shaped, asymmetrical wall of the second housing.

According to a further embodiment of the charging socket, it is provided that the charging socket has an authorization device for authorizing a charging process, such as an RFID reading device or the like. The authorization device can be attached to the first housing, the second housing or a cover protecting the charging contacts.

The authorization device can read out coded information to what extent the user in question is authorized to access the charging socket. For example, information that is stored in an RFID tag of a charging plug can be read and processed by the RFID reading device.

The cover can be a removable cover or a cover that is held pivotably on the first housing.

Another embodiment of the charging socket is characterized in that the charging contacts have one or more power contacts L1 , L2 , L3 , N , PE have that are contacted with the interface.

Alternatively or in addition, it can be provided that the charging contacts have one or more signal contacts with the assignment CP , PP , Motor +, Motor feedback1, Feedback2, RFID reader or have status indicators that are contacted with the interface.

The first housing and / or the second housing can be water- and / or dust-resistant according to protection class IP67 or higher, in order to protect the electronics from environmental influences.

As an alternative or in addition, the first housing and the second housing can have a seal in a connection area for a water- and / or dust-resistant connection.

It can be provided that components of the charging controller are partially or completely encapsulated in a plastic. In this way, the components of the charging control can be protected from environmental influences in a simple manner

It can be provided that the second housing has a network connection, the network connection being set up for the detachable connection of network lines. For example, the mains connection can have spring-loaded terminals for connecting mains lines.

The charging control can have one or more of the following components: current measurement, fault current detection, locking actuator control, power switching, energy meter, network connection. The network connection can be, for example, a wired network connection, such as Ethernet or the like, or a wireless network interface, such as WLAN, Bluetooth, NFC or the like.

According to a second aspect, the invention relates to street lighting, with a lighting device for illuminating a street section, with an energy supply connection for operating the lighting device and with a charging socket according to the invention.

In particular, the charging socket according to the invention can be retrofitted to existing street lighting in order to increase the area-wide availability of charging sockets for electric vehicles.

Due to the plug connection according to the invention between the charging contacts and the charging controller, such charging points can be retrofitted quickly and inexpensively on masts of street lighting. For example, a charging socket according to the invention can be used in a lamp post of street lighting.

According to a third aspect, the invention relates to a wall box for charging an electric vehicle, set up for wall mounting or flush mounting, with a charging socket, the charging socket being formed in the manner according to the invention. The wall box can be installed easily and quickly without errors, since the connection between the charging contacts and the charging controller is predetermined by the interface with the plug connection.
