Definitions

  • the present invention relates to a charging station for charging an electric vehicle.
  • different variants of charging stations are used. Basically, the different variants of charging stations can be divided into two groups depending on the provision of a charging cable.
  • a first group of charging stations are usually installed in the private sector and already include the appropriate charging cable for the vehicle, which is firmly connected to the housing.
  • These types of charging units usually offer the possibility of tidying up or storing the charging cable, for example by being able to roll it up around the charging station and to place the plug in a parking position.
  • Charging stations of a second group do not include a charging cable mounted on the device, but require the use of their own separate charging cable.
  • Such charging stations are often found in public areas, where electric cars are usually connected to the existing charging stations with the vehicle owner's charging cable or the vehicle's own charging cable.
  • the usual variants of charging stations often have in common that they are permanently installed in a housing. Due to the targeted design for a special application, charging stations usually have a high level of complexity. Since the different variants inevitably require different configurations, in particular different housing shapes, different tools must be used accordingly in the production of charging stations. This variety of variants causes a large number of different parts.
  • a charging station for charging an electric vehicle which includes a housing, a mains power connection and a charging current connection as well as a control device.
  • the charging station comprises an exchangeable adapter connection and an exchangeable adapter that can be mounted on it for delivering charging current.
  • the charging station initially serves as an interface between the mains power provided by the respective energy supplier, which is fed into the charging station via the mains power connection, and the charging current connection, via which the electric vehicle is ultimately charged.
  • the control device can, for example, take on tasks from the areas of conditioning, charging monitoring, signalling, authorisation, billing and control.
  • charging current can be delivered exclusively via the change adapter connection and the change adapter that can be mounted on it.
  • the charging station can only deliver charging current when the interchangeable adapter is mounted on the interchangeable adapter port.
  • a flow of charging current can only be delivered via the changeover adapter.
  • the charging station can essentially Can be manufactured across all variants as a component that is always designed in the same way. Due to the presence of an interchangeable adapter, the variant-specific differences in the charging station can be implemented on the hierarchy of the various interchangeable adapter variants. As a result, a large number of identical parts can be guaranteed for a large number of different variants of the charging station. On the production side, a platform production of many components of the charging station can be realized.
  • the change adapter can in principle be changed at any time. In addition to advantages in terms of production, this also opens up the possibility of converting charging stations that have already been manufactured, sold and/or installed to a different interchangeable adapter or of continuing to operate the charging station at a different location with different equipment.
  • the interchangeable adapter connection of the charging station can preferably be formed in the housing, with the interchangeable adapter being able to be mounted on the interchangeable adapter connection by means of a support structure.
  • a support structure can also essentially have a constant design.
  • the support structure can have the same geometric structure for connection to the housing. This also makes it possible to separate the housing and change adapter from one another.
  • different interchangeable adapters can be used in a housing that has already been installed, so that the charging station can be adapted to the respective area of application.
  • housings and interchangeable adapters that are to be disposed of can be fed to the respective waste treatment processes in a simple manner.
  • the interchangeable adapter can be mounted on the interchangeable adapter by means of a support structure, even parts of the interchangeable adapter can be designed as a platform product or identical part.
  • the support structure can provide a platform as the starting structure, which has an essentially constant design. To put it more precisely, the support structure can be designed in such a way that only a single tool has to be used to produce the support structure itself. All other modifications of the support structure, for example to adapt it to the different variants of charging station, can be adapted to the individual embodiments by slight modifications. As a result, it can be achieved that both the housing and the supporting structure can be developed and manufactured as platform products or identical parts across variants.
  • the charging station can be used, for example, in the form of a wall charging station, which is also referred to as a wall box.
  • the housing is typically mounted on a wall, for example of a building.
  • the charging station can also be mounted on a free-standing structure such as a stele, wall or pillar. The structure on which the charging station is mounted must be selected according to the respective application.
  • the interchangeable adapter can be designed as a charging cable adapter, comprising a charging cable attached to the support structure and an electrical cable connection piece for electrically connecting the charging cable to the charging current connection.
  • This embodiment relates to a variant of charging stations, also known as parking dock charging stations. Because the interchangeable adapter is designed as a charging cable adapter, only one charging cable can be provided in the charging station, which can be rigidly connected to the charging station. Charging stations according to this embodiment can therefore preferably be installed in private rooms for vehicle owners of a certain type of vehicle. Nevertheless, manufacturer-specific charging bays can be provided in public spaces, which can prevent unauthorized customers from being supplied with charging current simply because of the parking dock configuration. Because the interchangeable adapter is designed as a charging cable adapter, it can also be avoided that other devices are connected to the charging station. Ultimately, this can significantly improve security in both private and public spaces.
  • the interchangeable adapter can be securely installed purely via the interface between the interchangeable adapter connection and the interchangeable adapter, without further securing or fixing the charging cable being provided must.
  • it can be avoided that a tensile load of the charging cable is transferred to the charging current connection. Consequently, the operational reliability of the charging station can be improved in this way.
  • an electrical cable connection piece is provided for electrically connecting the charging cable to the charging current connection means that the charging cable can be wired to the electrical charging current connection in a simple, reliable, cost-effective manner inside the charging station.
  • the support structure can have a through hole for attaching the charging cable, it being possible for the charging cable to be attached to the support structure, preferably with a screw connection. Because the support structure has a through-hole for attaching the charging cable, the support structure can be manufactured as a platform product across all variants, which means that ideally only a single tool is required to produce the support structure. The support structure can therefore be adapted to the required geometry of the current exemplary embodiment by simply reworking the support structure. This saves costs, conserves resources and shortens production times.
  • the charging cable can be attached to the supporting structure, preferably with a screw connection, means that the assembly of the charging cable with the supporting structure can be considerably simplified.
  • the use of a screw connection allows non-destructive maintenance of the charging station to be carried out in the event of a cable replacement, for example caused by a defective cable.
  • a parking socket for accommodating a charging cable plug is preferably provided on the support structure, with the parking socket particularly preferably having a sensor for detecting the removal of the charging cable plug.
  • the sensor can detect removal of the charging cable connector and thus, for example, make the charging station ready for charging/wake up. At the Inserting the charging cable plug into the parking socket can also switch off the charging station.
  • the interchangeable adapter can be designed as a socket adapter, comprising a socket arranged on the support structure and an electrical plug connection piece for electrically connecting the socket to the charging current connection.
  • This embodiment relates to a variant of charging stations, also known as shutter/socket or shutter charging stations.
  • the interchangeable adapter is designed as a socket adapter, basically any compatible cable with a suitable plug can be used as a charging cable together with the charging station for charging an electric vehicle.
  • Another advantage is that the charging cable can be tidied up or stowed away after use and does not have to remain connected to the charging station unnecessarily. This can prevent property damage and personal injury. Furthermore, this allows the charging station to be manufactured, transported and assembled as a compact component.
  • the support structure can also be manufactured as a cross-variant platform, which means that ideally only a single tool is required to produce the support structure, at least for the production of a plastic injection-molded part blank of the support structure.
  • the socket adapter can include a socket cover for closing the socket.
  • the socket outlet can be effectively protected against the effects of the weather and/or other disruptive influences when not in use, as a result of which the operational reliability of the charging station can be significantly improved.
  • the socket adapter can have a socket cover in conjunction with a pretensioning device, which can ensure that the socket cover automatically moves into a closed position after the charging station has been used and the charging cable has been removed, in which the socket is closed by the socket cover.
  • the socket adapter can include a charging cable with a charging cable plug that is designed and set up to be inserted into the socket. This allows a with charging cable compatible with the charging station must be provided together with a compatible charging cable connector.
  • the changeable adapter connection and the changeable adapter can be releasably connected to one another, with the releasable connection preferably having a snap-in, click, plug-in, screw and/or rotary connection.
  • the adapter connection and the adapter are detachably connected to one another, maintenance of the charging station can be simplified and non-destructively, and the adapter can also be exchanged for a different embodiment after the charging station has been installed.
  • a charging station that was originally delivered with an interchangeable adapter designed as a charging cable adapter can be converted into a charging station that has an interchangeable adapter designed as a socket adapter. Due to the fact that a locking, click, plug, screw and/or rotary connection is provided, a tool-free or largely tool-free assembly, repair or dismantling of the change adapter on or from the change adapter connection can also take place.
  • a sealing means in particular an elastomer seal, is arranged between the change adapter connection and the change adapter. Because a sealant is arranged between the interchangeable adapter connection and the interchangeable adapter, moisture can be prevented from getting into the interior of the charging station.
  • the charging station can include a wall mounting device for fastening it to a wall. This ensures flexible and safe installation of the charging station at a suitable location while complying with the installation specifications.
  • the housing can also have a housing cover, wherein the housing cover can preferably include input means and/or display means electrically connected to the control device.
  • the housing has a housing cover, assembly, maintenance and dismantling of the charging station can be simplified considerably. For example, this allows mains power connections and other cable connections and Fastening devices are made accessible inside the charging station. Furthermore, this means that defective components of the charging station can be easily replaced without having to dismantle the charging station. Furthermore, this allows storage space to be provided in the charging station.
  • the housing cover includes input means and/or display means electrically connected to the control device, an interactive interface between the user and the control device can be made available in the housing cover.
  • the input means and/or display means can include LEDs that provide information about the device status of the wall station. As a result, for example, the assembly of the charging station can be explained and carried out simply, clearly and safely.
  • the input means and/or display means can include an input field via which a user can transmit data to the control device, in particular authorization data and/or load-specific data.
  • the input means and/or display means can include a display that can be used to display user-specific, charge-specific or non-specific information. It is advantageous if the input means and/or display means and/or the control device preferably have an intranet and/or internet interface.
  • the control device is designed and set up to detect the presence of at least one type of interchangeable adapter. Presence can mean an electrical installation in the charging station. Because the control device is designed and set up to detect the presence of at least one type of interchangeable adapter, a program structure stored in the control device can be called up, for example depending on the detection of which type of interchangeable adapter is present.
  • the control device can preferably include a data record of previously stored types of interchangeable adapters. If the detection shows, for example, that a previously stored type of interchangeable adapter is present, the control device can, for example, release a charging current and/or set a charging current. Furthermore, the user and/or a person responsible for installing the charging station can be informed by the control device that or to what extent the charging station is ready for operation.
  • the housing can be designed to accommodate a charging cable in it in a removable manner. This ensures that the charging cable can be stowed away properly between two plug-in cycles.
  • the exchange adapter connection can be designed as a cutout in the housing. This has the advantage that, on the one hand, material costs can be saved and, on the other hand, existing charging stations can be retrofitted accordingly by introducing a suitable recess.
  • the exchange adapter connection is arranged on a bottom side of the housing. It can thereby be achieved that the charging cable protrudes from the underside of the housing or can be plugged into an underside of the housing, as a result of which accidental contact with the cable can be reduced as far as possible. In addition, this can prevent foreign bodies and/or moisture from reaching the interface between the change adapter connection and the change adapter.
