Definitions

  • the invention relates to a connection device for charging an electric vehicle, comprising a main unit on which a charging socket for plugging in a charging cable for connection to the electric vehicle is arranged or to which the charging cable is directly connected.
  • Electric vehicles are connected to a DC or AC power supply line to charge the drive battery (s) for ferry operation.
  • connection devices in the form of boxes or columns have been established that are set up in private or public traffic areas and can be connected to the electric vehicles for charging.
  • Terminal boxes are usually mounted on a wall and are also referred to as "wall boxes”. As a rule, charging stations are free-standing.
  • connection devices are usually connected to a power supply network via a multi-phase, typically three-phase connection cable.
  • the connection device offers the possibility of plugging in a connection cable (charging cable) especially suitable for these purposes.
  • the charging cable can be permanently connected to the connection device for connection to the vehicle.
  • signal lines are also arranged in the charging cable, which serve to exchange signals or data and communicate with the parameters of the charging process between the connection device and the vehicle. The delivery of the charging current is also released via the signal line if suitable parameters for the charging process are available or have been set by the vehicle or the connection device.
  • connection device In addition to the contact options for the power supply cable and the charging cable to the vehicle, the connection device usually has safety devices that protect against overcurrent and fault current during the charging process.
  • Current converters can also be provided if current of a different voltage and / or a different type of current is required for the charging process.
  • the type of current is understood to mean alternating current (AC) or direct current (DC). Due to the connection capacities of the connection devices in the range of about 10 to a few 10 kW, the laying and installation of a usually 5-core cable with a conductor cross-section of typically 4 mm 2 or more is necessary for the power supply.
  • Such a connection cable which is quite massive for typical private house installations, is complex to lay and should only be connected to the connection device by qualified electricians.
  • connection device due to a change of vehicle, it may be necessary to change the position of the connection device. Such a change of position may be necessary when changing to a different vehicle model in which the charging cable is plugged into another location on the vehicle. In this case, the connection device must be dismantled and reassembled at a different location. There may also be a need to provide a charging option with a different (plug) standard when changing vehicles. In this case, too, reinstallation of the connection device leads to great expense and effort.
  • a connection device is characterized by an additional connection with a separate additional housing on which an additional charging socket for a further charging cable is arranged or to which the further charging cable is directly connected.
  • the additional connection makes it possible to provide a further charging option for the electric vehicle without having to duplicate the required functional components of the connection device, for example for communication with the vehicle and for activating the charging voltage.

  • Signal terminals for connecting a signal cable that leads to the additional connection can also be present on the main unit.
  • Power cables and signal cables can be combined in a common cable.
  • the terminals enable the additional connection to be connected (also at a later date).
  • the power output terminals and / or the signal terminals are preferably arranged on the connection base if the main part of the connection device is designed in two parts, as described above. In that case, the additional Finally installed without having to intervene in the module unit.
  • the advantage of dividing the main part in two specifically the simple dismantling and exchangeability of the module unit, remains even with the additional connection installed.
  • the charging socket or the charging cable of the main unit or the charging socket or the further charging cable of the additional connection can optionally be used for charging the electric vehicle.
  • This can be controlled, for example, by a control device in the main unit.
