[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-223345 Summary of the Invention [Problem to be solved by the invention]

[0004] The parking lot described in the above patent document is designed to be convenient for residents, but because it is not exclusively for residents but also has external users in mind, the electricity charges incurred for vehicle charging are separate from the electricity charges for electricity used in the user's room. As a result, charges are settled separately, and the electricity charges for vehicle charging are set at a relatively high level. However, in the case of parking lots in apartment buildings, if residents use a vehicle charger, the electricity bill (power usage) can be added to the power used in the room, so the cost of charging the vehicle will not be too expensive.

[0005] In view of these problems, the present invention aims to provide an apartment complex vehicle charging system that adds the amount of electricity used when charging a vehicle using a vehicle charger installed in an apartment complex to the electricity used in the user's room. [Means for solving the problem]

At the same time, after authenticating the information input to the authentication information input unit, the charging control device selects an unused vehicle charger from among the plurality of vehicle chargers and displays the number of the selected vehicle charger on the display unit. It is characterized by: With this configuration, the power to charge the vehicle is supplied from the secondary side of the watt-hour meter in the user's room, so there is no need to calculate the electricity charges for using the vehicle charger separately, and the electricity charges for charging the vehicle do not become expensive. In addition, multiple residents can charge their vehicles at the same time, and since the user does not have to select the vehicle charger to use, there is no need to provide an operation unit on the vehicle charger, and a simple configuration is sufficient.

[0007] The invention of claim 2 is characterized in that, in the configuration described in claim 1, the authentication information input unit has a reading unit that reads information from the held-up authentication means, and the authentication means is a card key carried by the resident to unlock the entrance to the room. According to this configuration, authentication can be performed using the card key that unlocks the front door, so no separate authentication means is required, and authentication can be performed with a simple operation, making it easy to charge the vehicle. [Effects of the Invention]

[0009] According to the present invention, the power for charging the vehicle is supplied from the secondary side of the electricity meter in the user's room, so there is no need to separately calculate the electricity charges for using the vehicle charger, and the electricity charges for charging the vehicle do not become expensive. [Brief explanation of the drawings]

[0010] [Figure 1] 1 is a schematic diagram illustrating an example of an apartment building vehicle charging system according to the present invention. [Figure 2] FIG. 2 is an explanatory diagram of a charge control device. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. Fig. 1 is a schematic diagram showing an example of an apartment building vehicle charging system according to the present invention, in which 1 is a charger (vehicle charger) for charging a vehicle, 2 is a switching device (power source switching device) that switches the power source supplied to the vehicle, and 3 is a charging control device that controls the switching device 2. A plurality of chargers 1 are installed, and a switching device 2 is provided for each charger 1. Note that B indicates a room in apartment building A, 5 indicates a watt-hour meter, 6 indicates a distribution board, and 7 indicates a vehicle to be charged.

[0012] The switching device 2 has a power supply side terminal 2a, a load side terminal 2b, a switching device communication unit 2c that communicates with the charge control device 3, and the like. The number of power supply side terminals 2a is the same as the number of rooms B, and cables C connected to the secondary side of the watt-hour meter 5 installed in each room B are drawn in. The drawn-in cables C are connected to the individual power supply side terminals 2a, and are configured so that any one of the cables C can be selected. On the other hand, the charger 1 is connected to the load side terminal 2b, and any one of the power supply side terminals 2a and the load side terminal 2b is connected within the switching device 2. That is, any one of the cables C is selected and connected to the charger 1, and power is supplied. This switching may be performed by a mechanical switching mechanism using a relay, or by a semiconductor switch using a FET, etc. The switching is performed when the switching device communication unit 2c receives a control signal from the charging control device 3.

[0013] Fig. 2 shows a block diagram of the charge control device 3. As shown in Fig. 2, the charge control device 3 includes an authentication unit (authentication information input unit) 31, a charge control unit 32, a communication unit 33 that communicates with the switching devices 2, and the like, and is connected to each switching device 2 via a signal line L. Authentication unit 31 has display unit 31a and reading unit 31b, and when the user holds card key (authentication means) 10 over reading unit 31b, authentication unit 31 reads the information on card key 10. Display unit 31a displays the numbers of chargers 1 that the user can use. Card key 10 is a key used to unlock the front door of personal room B, and here it is a card key (e.g., an IC card) that can transmit information simply by holding it over the door, but it may also be a magnetic card that is inserted into an insertion unit for authentication.

[0014] The charging control unit 32 is configured with a CPU, memory, etc. (not shown). The memory stores card key information for each room B in the apartment building, which is required for authentication, linked to a room number, and identifies the room number based on the information in the storage unit from the information on the card key 10 entered into the authentication unit 31. The charging control unit 32 also controls the selection of an available charger 1.

[0015] Vehicle charging using the apartment complex vehicle charging system configured in this manner is performed as follows: A user charging vehicle 7 first performs authentication by holding card key 10 over authentication unit 31. Charging control unit 32 obtains the user's room number from the information read by authentication unit 31 from the held-up card key 10, by referencing the memory unit of charging control unit 32. If the read information is found in the storage unit, the charging control unit 32 recognizes that the user is a resident of an apartment building and selects a charger 1 to use for charging. The charger 1 to be selected is determined by selecting one of the unused chargers 1 from the multiple chargers 1 in a predetermined order. The number of the selected charger 1 is displayed on the display unit 31a.

[0016] In addition, based on the room number obtained from the memory unit, a switching signal is sent to the switching device 2 of the selected charger 1, the internal connection is switched, and it is set to the cable C connected to the secondary side of the electricity meter 5 in that room B. In this way, charging power is supplied from the secondary side of the watt-hour meter 5 in the user's room B to the charger 1 used by the user for charging, and the amount of power is measured by the watt-hour meter 5 in the user's room B. When charging is completed, the connection within the switching device 2 is released and the device is put into an open state. Furthermore, unless the authentication unit 31 authenticates the held-up card key 10, charging control will not start.

[0017] In this way, the power to charge the vehicle 7 is supplied from the user's room B, so there is no need to calculate the electricity charges for using the charger 1 separately, and the electricity charges for charging the vehicle do not become expensive. Furthermore, since authentication is performed using the card key 10 that unlocks the front door of room B, no separate authentication means is required, and authentication can be performed with a simple operation, making it easy to charge the vehicle. Furthermore, since multiple chargers 1 are provided, multiple residents can charge their vehicles at the same time, and since the user does not have to select the charger 1 to use, there is no need to provide an operation unit on the charger 1, and a simple configuration is sufficient.

[0018] In the above embodiment, the switching device 2 and the charger 1 are configured independently, but they may be configured as an integrated unit in which the charging connector for connecting the vehicle 7 is pulled out from the switching device 2. Also, although authentication is performed using a card key, an operation unit such as a numeric keypad may be provided on the charging control device 3, and authentication may be performed by inputting a PIN number without using a card. Also, although a configuration including a plurality of chargers 1 is shown, only one charger may be used. [Explanation of symbols]
