Description

  The present invention relates to an improvement in a vehicle charging stand used for charging a vehicle equipped with an in-vehicle battery such as a plug-in hybrid vehicle or an electric vehicle.

Conventionally, as shown in Patent Document 1, a vehicle charging stand used for charging a vehicle equipped with an in-vehicle battery has been proposed. In such a vehicle charging stand, a charging current generating device that generates a charging current and a control device that monitors and controls the charging state of the vehicle to be charged are housed in a metal cabinet.
In recent years, a vehicle charging stand has been proposed in which charging information such as a charging end time, a charging completion notification, and charging information is transmitted to a mobile terminal such as a mobile phone possessed by the user. Such a vehicle charging stand has an antenna for transmitting and receiving to / from a mobile phone base station. However, if the antenna is housed inside a metal cabinet, the radio wave is naturally blocked by the cabinet. The antenna must be installed outside the cabinet. In general, it is conceivable to connect an antenna to the side surface of the cabinet by passing wiring from the incoming line portion communicating with the inside of the cabinet to the outside of the cabinet.
