In addition, when charging is not in progress, either when the vehicle information exceeds a predetermined data size, when there is vehicle information with a high priority, or when there is vehicle information with a high evaluation value Perform batch transmission. Note that if the vehicle-side PLC communication control unit 26 detects whether or not charging is currently being performed, it is not necessary to determine again whether or not a PLC communication line has been established.
  • the capacity of the storage unit 27 can be effectively used to the maximum extent by deleting the vehicle information that has been transmitted from the storage unit 27. Further, when the transmission of the vehicle information cannot be completed and the communication line by the PLC is not established, the vehicle information lower than the predetermined priority is deleted. Thereby, even if transmission of vehicle information is not completed, when a communication line by PLC cannot be established, vehicle information with low priority can be deleted, and a free area in the storage unit 27 can be effectively secured.
  • the vehicle-side PLC communication control unit 26 does not issue a command to turn on the leakage interrupt relay 31 to the charging control unit 25b when receiving information on leakage from the leakage breaker 3. That is, when a leakage occurs in the charging cable (power line) 4 and the leakage breaker relay 31 is turned off, a control signal Sg for turning on the leakage breaker relay 31 is transmitted to cause the leakage breaker relay 31 to instantaneously However, it is possible to prevent a problem that turns ON.
  • the present invention has been specifically described based on several embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. It is.
  • the communication line establishment condition by the PLC while charging is stopped is not limited to the above three pattern conditions, but may be changed to a desired condition according to the user's desire.
  • the description has been made on the assumption that an in-vehicle charging device mounted on an EV or HEV that can be charged from the outside, but the present invention is not limited to this, and a storage battery mounted on a normal gasoline vehicle. Needless to say, the present invention can also be applied to an in-vehicle charging apparatus for charging a battery.
  • the present invention can be used as an in-vehicle charging device for HEVs and EVs, but can also be effectively used as an in-vehicle charging device for general vehicles such as gasoline vehicles.
