  The first control unit 2 of the intercom apparatus 1 periodically activates the fee information acquisition unit 8 to perform communication with the server 80, and acquires information on the hourly fee from the server 80 (FIG. 2). S1). Table 1 below is an example of charges by time zone. Charge A from 23:00 to 7:00 the next day is the lowest price, and charge B from 7:00 to 10:00 and from 17:00 to 23:00 is the second lowest. The charge C from 10:00 to 17:00 is the highest value. FIG. 6 is a graph showing the setting of the charge for each time zone.

  When a resident of the house 100 connects the plug 43 of the charging control device 30 to the socket 67 of the electric vehicle 60 at the start of charging (S2), the CPLT communication unit 34 exchanges a CPLT signal with the electric vehicle 60. On the electric vehicle 60 side, when an electrical connection state with the charge control device 30 is established, a power supply permission signal is output to the charge control device 30 to prepare for power supply from the charge control device 30. The second control unit 31 of the charging control device 30 controls on / off of the opening / closing element 32 based on the CPLT signal from the electric vehicle 60 and the control signal from the intercom device 1, and controls to instruct the start of power feeding Since no signal is input, the switching element 32 is turned off (opened) (S3). Moreover, the 2nd control part 31 displays a power supply stop state by turning off the light emitting diode lighted at the time of power supply (S4).

  Next, when the resident inputs the desired charging completion date and time using the operation unit 6 of the intercom device 1 (S5), the setting information of the desired charging completion date and time is input from the operation unit 6 to the first control unit 2. In the first control unit 2, based on the information on the charge by time zone acquired in S1 and the setting of the desired charging completion date and time, the time zone for performing the charging operation until the desired charging date and time (hereinafter, this time zone). Is referred to as a charging time zone) (S6).

  FIG. 4 is a flowchart of a process in which the first control unit 2 sets the charging time zone, and the operation of the first control unit 2 will be described with reference to this flowchart. When the plug 43 of the charging control device 30 is connected to the socket 67 of the electric vehicle 60, the first control unit 2 connects the charging capacity of the secondary battery 61 from the charging unit 63 of the electric vehicle 60 via the charging control device 30. Is confirmed (S41). The first control unit 2 calculates the charging time required to charge the required charging capacity obtained in S41 (S42), and calculates the time obtained by adding the required charging time to the current date and time as the shortest charging completion date and time. (S43).

  If the desired charging completion date and time set in S5 is before the shortest charging completion date and time (Yes in S44), the first control unit 2 causes the display unit 5 to display the shortest charging completion date and time (S45), To the shortest charging completion date and time is set as a charging time zone (S46).

  On the other hand, if the charge completion desired date and time set in S5 is later than the shortest charge completion date and time (No in S44), the first control unit 2 reads the charge by time zone from the charge information acquisition unit 8, and from the present time The charges by time zone until the desired charging completion date and time are rearranged in ascending order of unit price (S47). For example, when the current time is time t1 in FIG. 6 and the charge completion desired date and time is time t2 on the next day and the time zone charges are set as shown in Table 1, the first control unit 2 performs time t1 to time t2. Table 2 shows the results of sorting the charges by time zone in ascending order. In addition, the 1st control part 2 has each assigned the number K which starts from the 1st in the order with a cheap electricity bill to the charge according to time zone from the time t1 to the time t2.

  Next, the first control unit 2 sets the remaining charging time to the necessary charging time (S48), and after setting the number K to 1 (S49), determines whether the remaining charging time is longer than zero. (S50). If the remaining charging time remains (Yes in S50), the first control unit 2 obtains a chargeable time T at the Kth time zone charge (S51), and charges the start time of this time zone charge. The start time is set (S52), and the end time of the charge for each time zone is set as the charge end time (S53). The first control unit 2 sets the time obtained by subtracting the time T obtained in S51 from the remaining charge time as a new remaining charge time (S54), increments the number K by 1, and then returns to S50 to return the remaining charge time to 0. Determine whether it is longer. If it is determined in S50 that the remaining charge time is less than 0 (No in S50), the first control unit 2 stores one or more time zones set in the processing in S50 to S55 as a memory (not shown). To complete the setting of the charging time zone (S46).

  When the first control unit 2 completes the setting of the charging time zone by performing the above processing, the notification unit 9 notifies the completion of the setting (S7).

  Thereafter, when the charging start time determined in S6 comes, the first control unit 2 outputs a transmission command for transmitting a power supply start command to the first communication unit 7 (S8), and receives the transmission command to perform the first communication. The unit 7 transmits a power supply start command to the charge control device 30 (S9). When receiving the power supply start command transmitted from the intercom device 1, the second communication unit 37 of the charge control device 30 outputs the power supply start command to the second control unit 31 (S10). The second control unit 31 receives the power supply start command, performs power supply start control, closes the opening / closing element 32 (S11), and displays the power supply state by causing the LED for power supply display to emit light. (S12). In addition, although the alerting | reporting operation | movement is performed by the display part 36 alert | reported with light, you may alert | report the start of electric power feeding by providing a sounding means like a buzzer as an alerting | reporting part, and sounding a sounding means. At this time, electric power is supplied to the electric vehicle 60 via the charging control device 30, and the charging unit 63 of the electric vehicle 60 starts charging the secondary battery 61. When the second control unit 31 performs power supply start control, the second control unit 31 outputs a transmission command of a response signal informing the start of power supply to the second communication unit 37 (S13), and the second communication unit 37 receives the transmission command and responds. A signal is transmitted to the intercom apparatus 1 (S14).

  In the intercom device 1, when the response signal received by the first communication unit 7 is output to the first control unit 2 (S15), the first control unit 2 notifies that the power supply to the electric vehicle 60 has started. The notification command to be output is output to the notification unit 9 (S16). Since the notification unit 9 receives the notification command and notifies the charging control device 30 that power supply has started with an image or sound (S17), the resident has received the notification operation of the notification unit 9 and has started power supply. Can be recognized.

  Further, when the charging end time determined in S6 comes, the first control unit 2 outputs a transmission command for transmitting a power supply stop command to the first communication unit 7 (S18), and receives the transmission command to perform the first communication. The unit 7 transmits a power supply stop command to the charge control device 30 (S19). When receiving the power supply stop command transmitted from the intercom device 1, the second communication unit 37 of the charge control device 30 outputs the power supply stop command to the second control unit 31 (S20). The second control unit 31 receives a power supply stop command, performs power supply stop control, opens the opening / closing element 32 (S21), and turns off the power supply display LED to indicate that the power supply is stopped. (S22). Note that a sounding means such as a buzzer may be provided as a notification unit, and the sounding means may be sounded to notify that power feeding has been stopped. At this time, power supply to the electric vehicle 60 is cut off, and charging of the secondary battery 61 by the charging unit 63 is stopped. In addition, when the second control unit 31 performs the power supply stop control, the second control unit 31 outputs a transmission command for transmitting a response signal including information on the power supply stop and information on the amount of charge in the charging time period to the second communication unit 37. (S23) Upon receiving this transmission command, the second communication unit 37 transmits a response signal to the intercom apparatus 1 (S24).

  In the intercom device 1, when the response signal received by the first communication unit 7 is output to the first control unit 2 (S25), the first control unit 2 notifies that the power supply to the electric vehicle 60 is stopped. The notification command to perform is output to the notification unit 9 (S26). Since the notification unit 9 receives the notification command and notifies the charging control device 30 that the power supply has been stopped with an image or sound (S27), the resident receives the notification operation of the notification unit 9 and starts the power supply. Can be recognized.

  The above shows the operation in one charging time zone. When a plurality of charging time zones are set before the charging completion time comes, the processing from S8 to S27 is repeated every time the charging start time comes. Done.

  Then, as shown in FIG. 3, the second control unit 31 of the charging control device 30 detects a full charge based on the CPLT signal from the electric vehicle 60 during power feeding from the charging control device 30 to the electric vehicle 60 during the charging time period. Then (S28), the second control unit 31 opens the switching element 32 (S29). Further, the second control unit 31 displays a charging completion state by blinking an LED for power supply display, for example (S30), and outputs a transmission command of a response signal informing the completion of charging to the second communication unit 37. (S31) Upon receiving this transmission command, the second communication unit 37 transmits a response signal to the intercom apparatus 1 (S32).

  In the intercom device 1, when the response signal received by the first communication unit 7 is output to the first control unit 2 (S33), the first control unit 2 notifies that the charging of the electric vehicle 60 is completed. A notification command is output to the notification unit 9 (S34). Since the notification unit 9 receives the notification command and notifies the charging of the electric vehicle 60 with an image or sound (S35), the resident is charged with the electric vehicle 60 in response to the notification operation of the notification unit 9. Recognize that it has been completed. When the resident determines that charging of the electric vehicle 60 has been completed based on the notification content of the notification unit 9 of the intercom device 1 and the display unit 36 of the charge control device 30, the resident plugs in the charge control device 30. 43 is removed from the socket 67 of the electric vehicle 60 (S36).

  At the time when the charging time period ends before full charging (for example, S22 and S27 in FIG. 2), the resident receives the notification of power supply stop and plugs the plug 43 of the charging control device 30 into the socket 67 of the electric vehicle 60. 3 is not performed, the process shown in the flowchart of FIG. 3 is not performed. In this case, the secondary battery 61 of the electric vehicle 60 is not fully charged but the amount of charge when the plug 43 is removed.

  In the flowchart shown in FIG. 2, the resident sets the desired charging completion date and time in S5. However, in addition to the desired charging completion date and time, a desired charge amount may be set. In this case, the secondary battery 61 is charged. When the amount reaches the desired charge amount, it is regarded as full charge, and the processes of S28 to S30 are performed.

  As described above, the intercom apparatus 1 according to the present embodiment is a call unit that performs an extension call with the handset 20 (in the present embodiment, the call processing unit 3, the speaker 3a, and the microphone 3b). The first communication unit 7 that communicates with the charging control device 30 that controls the power supply from the power source to the power storage device of the electric vehicle 60, and the control signal that controls the operation of the charging control device 30 as the first communication. The 1st control part 2 made to transmit to the charge control apparatus 30 from the part 7 is provided.

  Thereby, the operation state of the charging control device 30 that controls the power supply to the electric vehicle 60 can be controlled from the intercom device installed in the house. Therefore, there is no need to go to the outdoors where the charge control device 30 is placed in order to operate the charge control device 30, and the convenience is improved. In addition, since the operation state of the charging control device 30 can be controlled using an existing intercom device in the house 100, there is an advantage that it is not necessary to install a dedicated control device in order to control the charging control device 30.

  Further, the first control unit 2 of the intercom device 1 sends a control signal to the first communication unit 7 when a corresponding time (for example, charging start time, charging end time) is reached based on the time setting related to the power feeding operation of the charging control device 30. To the charging control device 30.

  Thus, since the intercom device 1 transmits the control signal to the charging control device 30 when the corresponding time comes based on the time setting, it is desired to set the time for charging according to the convenience of the user. The battery can be charged at the time.

  Moreover, the intercom apparatus 1 of this embodiment is provided with the charge information acquisition part 8 which acquires the charge according to time zone of the commercial AC power supply 50 which is one of the power supplies as the charge information of the power supply. In the 1st control part 2, based on the charge information which the charge information acquisition part 8 acquired, the control signal which performs the electric power supply to the electric vehicle 60 in the time zone where an electricity bill is cheap compared with other time zones is provided. The first communication unit 7 transmits to the charge control device 30.

  As a result, when the electricity rate changes for each time zone, the electric vehicle 60 is charged by supplying power to the electric vehicle 60 during a time zone when the electricity rate is cheaper than other time zones. The necessary electricity bill can be suppressed. In addition, the time period when the electricity rate is cheap is a time period when the power demand is less than other time periods. By using the power of such a time period for charging the electric vehicle 60, the load on the power system is reduced. Can be leveled.

  In addition, the intercom device 1 includes a notification unit 9 (in the present embodiment, configured by a display unit 5 including a liquid crystal display unit and a speaker 3a) that performs a notification operation for a user in the building. When the first communication unit 7 of the intercom device 1 receives the operation information indicating the operation state from the charge control device 30, the first control unit 2 notifies the operation state of the charge control device 30 based on the received operation information. Let you know.

  Thereby, the user in the building can grasp the operating state of the charging control device 30 from the notification content of the notification unit 9.

  By the way, in this embodiment, the commercial alternating current power supply 50 and the storage battery 54 which stores the generated electric power of the solar cell panel 52 which is a private power generation facility are used as a power source used for charging the electric vehicle 60. And the power conditioner 53 as a power supply control part gives priority to the charge of the storage battery 54 over the commercial AC power supply 50 in accordance with a control signal sent from the intercom device 1 via the management device 55, and the electric vehicle 60. It has a function to supply to.

  In the above-described embodiment, the charging time zone is set in the time zone where the unit price of the charge is relatively low based on the fee information acquired by the fee information acquisition unit 8, but the first control unit 2 of the intercom device 1 Then, while the stored amount of the storage battery 54 is available for charging, a control signal for supplying the stored amount of the storage battery 54 to the electric vehicle 60 with priority over the commercial AC power supply 50 may be transmitted to the power conditioner 53. The operation in this case will be described below.

  The management device 55 periodically acquires the amount of power stored in the storage battery 54 from the power conditioner 53. The first control unit 2 of the intercom device 1 periodically acquires the amount of electricity stored in the storage battery 54 from the management device 55, and when the amount of electricity stored can be used for charging the electric vehicle 60, the data on the amount of electricity stored is the charge information. Output to the acquisition unit 8. The charge information acquisition unit 8 stores, as power supply charge information, the amount of electricity stored in the storage battery 54 as power having a unit price (for example, 0 yen / kWh) lower than the charge unit price of the commercial AC power supply 50, and the table in Table 1 described above. To remember. And when the 1st control part 2 sets a charging time slot | zone according to the flowchart of FIG. 4, first, it subtracts the chargeable time of the storage battery 54 with the cheapest unit price from the remaining charging time first, and a new remaining charging is performed. Then, based on the charge for each time zone of the commercial AC power supply 50, the above-described processing of S47 to S55 is performed to determine the charging time zone.

  When the charging time zone is set in this way, the first control unit 2 of the intercom device 1 starts charging according to the setting of the charging time zone. Here, in the time zone in which the stored amount of the storage battery 54 is used, the first control unit 2 of the intercom device 1 gives a control signal for supplying the stored amount of the storage battery 54 to the electric vehicle 60 with priority over the commercial AC power supply 50. The data is transmitted to the power conditioner 53 via the management device 55. When the power conditioner 53 receives the control signal transmitted from the intercom device 1, the power conditioner 53 discharges the storage battery 54, converts the direct current power from the storage battery 54 into alternating current, and outputs the alternating current to the distribution board 51. The power conditioner 53 controls switching means (not shown) in the distribution board 51 to supply power supplied from the power conditioner 53 to the charge control device 30 from the distribution board 51. The electric power stored in the storage battery 54 can be supplied to the electric vehicle 60. When the storage battery 54 runs out of charge, the first control unit 2 of the intercom device 1 outputs a control signal for switching the power supply source to the distribution board 51 to the power conditioner 53. When the power conditioner 53 receives this control signal, the power conditioner 53 stops discharging the storage battery 54 and controls the distribution board 51 to switch the power supply source to the commercial AC power supply 50.

  Thereby, since the electric power generated by the private power generation facility, which is less expensive than the commercial AC power supply 50, can be used for charging the electric vehicle 60, the cost required for charging the electric vehicle 60 can be reduced.

  As shown in FIG. 10, a system including a power control unit 56 that switches a power supply source to the charging control device 30 to either the distribution board 51 or the storage battery 54 may be used. In this system, when the stored amount of the storage battery 54 can be used for charging the electric vehicle 60, the first control unit 2 of the interphone device 1 gives priority to the stored amount of the storage battery 54 to the commercial AC power supply 50 to the electric vehicle 60. A control signal to be supplied is output to the power control unit 56 via the management device 55. When the power supply control unit 56 receives this control signal, the power supply control unit 56 switches the power supply source from the commercial AC power supply 50 (distribution panel 51) to the storage battery 54, and uses the electric vehicle 60 to store the storage power of the storage battery 54. Can be used for charging. The power supply control unit 56 has a power conversion function for converting the DC power supplied from the storage battery 54 into AC and outputting the AC power to the charge control device 30. However, when the charging control device 30 has a function of supplying DC power to the electric vehicle 60 and the electric vehicle 60 can receive DC power, the power supply control unit 56 may not have the power conversion function. When the storage battery 54 runs out of charge, the first control unit 2 of the intercom device 1 outputs a control signal for switching the power supply source to the distribution board 51 to the power control unit 56 via the management device 55. . When the power supply control unit 56 receives this control signal, the power supply control unit 56 switches the power supply source to the commercial AC power supply 50 (distribution panel 51), and power is supplied from the commercial AC power supply 50 to the electric vehicle 60. Is called.

  By the way, in the intercom system of this embodiment, before starting the power supply to the electric vehicle 60, the vehicle information acquired from the electric vehicle 60 is authenticated, and when the authentication is successful, the electric power supply to the electric vehicle 60 is performed. May be started.

  The process of the intercom system in this case will be described based on the flowchart of FIG.

  First, in the state where the plug 43 of the charge control device 30 is connected to the socket 67 of the electric vehicle 60, a charge start operation is performed using the operation unit 6 of the intercom device 1, or a set charge start time is set. When it comes, the 1st control part 2 outputs the transmission request which requests | requires the vehicle information of the electric vehicle 60 to the 1st communication part 7 (S60). When the first communication unit 7 transmits the transmission request input from the first control unit 2 to the charge control device 30 (S61), the transmission request is received by the second communication unit 37 of the charge control device 30 (S61). The second communication unit 37 outputs the second control unit 31 (S62). The second control unit 31 receives this transmission request and outputs a transmission command to the second communication unit 37 (S63), and the second communication unit 37 sends a transmission request for requesting transmission of vehicle information to the electric vehicle 60. Wirelessly transmitted (S64). When the wireless communication unit 66 of the electric vehicle 60 receives the transmission request from the charging control device 30, it outputs the received transmission request to the control unit 62 (S65). When receiving the transmission request, the control unit 62 reads the vehicle information from the vehicle information storage unit 64 (S66), outputs the vehicle information to the wireless communication unit 66, and the vehicle is transmitted from the wireless communication unit 66 to the charging control device 30. Information is returned (S67). When the second communication unit 37 of the charging control device 30 receives the vehicle information of the electric vehicle 60, the second control unit 31 receives the vehicle information received by the second communication unit 37 and an authentication request for requesting authentication of the vehicle information. Is transmitted to the second communication unit 37 (S68). The 2nd communication part 37 receives the transmission request from the 2nd control part 31, and transmits vehicle information and its authentication request to the intercom apparatus 1 (S69). The first communication unit 7 of the intercom device 1 receives the vehicle information and the authentication request transmitted from the charging control device 30, and outputs the received vehicle information and the authentication request to the first control unit 2 (S70). When the vehicle information and the authentication request are input, the first control unit 2 outputs the vehicle information to the authentication processing unit 10 to perform authentication (S71). The authentication processing unit 10 performs authentication by comparing the vehicle information registered in advance with the vehicle information to be authenticated input from the first control unit 2, and returns an authentication result to the first control unit 2 ( S72). If the vehicle information to be authenticated is registered in advance (authentication is established), the first control unit 2 outputs a signal permitting charging of the electric vehicle to the first communication unit 7 (S73). If the 1st communication part 7 transmits the permission signal input from the 1st control part 2 to the charge control apparatus 30 (S74), this permission signal will be received by the 2nd communication part 37 of the charge control apparatus 30, and 2nd The data is output from the communication unit 37 to the second control unit 31 (S75). At this time, the second control unit 31 closes the opening / closing element 32 (S76), and starts supplying power to the electric vehicle 60. As a result of authentication by the authentication processing unit 10, if the vehicle information to be authenticated is not registered (authentication is not established), the first control unit 2 does not permit charging of the electric vehicle 60, so vehicle information is not registered. Electric power is not supplied to the electric vehicle 60.

  Thus, when the vehicle information acquired from the electric vehicle 60 by the charging control device 30 is transmitted from the charging control device 30 to the first communication unit 7, the interphone device 1 receives the vehicle information received by the first communication unit 7. An authentication processing unit 10 that performs authentication based on the above is provided. In the 1st control part 2, if the authentication by the authentication process part 10 is materialized, the permission signal which permits the electric power supply to the electric vehicle 60 will be transmitted from the 1st communication part 7 to the charge control apparatus 30.
