Here, since this response signal is for the ON signal from the interphone device 2, the control unit 32 determines that the transfer destination is the interphone device 2 and needs to be transferred (step S13). A response signal is transmitted from the 3rd communication part 34 to the 2nd communication part 12 of the charge control apparatus 1 (step S14). The second communication unit 12 outputs the received response signal to the second control unit 11 (step S15), and the second control unit 11 determines the transfer destination of this response signal and the presence / absence of transfer (step S16). Here, since the transfer destination of the response signal is the intercom device 2 and needs to be transferred, the second control unit 11 outputs the response signal to the second communication unit 12, and the second communication unit 12 A response signal is transmitted to the 1st communication part 24 of the intercom apparatus 2 (step S17). The first communication unit 24 outputs the received response signal to the first control unit 21 (step S18). Based on the response signal, the first control unit 21 indicates that the air conditioner 37 is turned on and displays the speaker 22a. Notification from the unit 25. At this time, it is preferable to start charging the power storage unit 31 of the electric vehicle 3 by the charge control device 1 in accordance with the operation of turning on the air conditioner 37. In this case, the charge capacity to the power storage unit 31 is impaired. In-vehicle equipment can be operated without any problems.

  Here, although the case where the air conditioner 37 of the electric vehicle 3 is turned on has been described as an example in the present embodiment, for example, the air conditioner 37 is turned off, the temperature or wind power of the air conditioner 37 is set, and the state of the air conditioner 37 is confirmed. The operation may be performed and is not limited to the present embodiment. Moreover, although there exists a defrosting function of the windshield of the electric vehicle 3 as one function of the air conditioner 37, the on / off operation | movement of this defrosting function may be sufficient.

  Furthermore, in the present embodiment, the air conditioner 37 is described as an example of a device constituting the in-vehicle device. However, the above device is not limited to the air conditioner 37, and the above-described light (headlight, interior light, etc.) 38 and crime prevention. The sensor 39 or the like may be used, and other devices may be used as long as they are mounted on the electric vehicle 3. When the above device is the light 38, an operation of turning on / off the light 38 by a control signal from the intercom device 2, an operation of checking the state of the light 38, and the like are assumed. Further, when the above-described device is the security sensor 39, the security sensor 39 has an operation for setting / clearing the alarm by the control signal from the intercom device 2, and a function for the security sensor 39 to notify an alarm sound. In some cases, an operation for setting / releasing the notification function, an operation for checking the state of the security sensor 39, and the like are assumed.

  Thus, according to the present embodiment, since the operation of the in-vehicle device can be controlled by the control signal from the intercom device 2 provided in the house, the convenience is improved, and the dedicated control device for controlling the in-vehicle device is further provided. Since it is not necessary to provide the cost, the cost increase can be suppressed. Further, when the air conditioner 37 is mounted as a device constituting the in-vehicle device as in this embodiment, the air conditioner 37 is operated (turned on) in advance, so that the interior of the vehicle is comfortable before the user gets on. Can be set to temperature. Furthermore, when the security sensor 39 is mounted as a device constituting the in-vehicle device as in the present embodiment, the control of the operation state of the security sensor 39, that is, the alarm setting and the alarm release by the security sensor 39 can be performed from inside the house. it can.
