JP20121655531A

  However, in the charging device of Patent Document 1, it is conceivable that the amount of electric power supplied to one vehicle is reduced when charging a plurality of vehicles using a charging cable and an outlet. In that case, there is a possibility that the charging time of each vehicle will be long.

  In addition, if a power supply path (single circuit) for supplying power (commercial power) to the charging cable and the outlet is individually allocated and power is supplied to the charging cable and the outlet from each power supply path, each vehicle However, in such a case, there is a risk of inconvenience such as an increase in equipment cost.

  The present invention has been made in view of the above circumstances, and mainly provides a vehicle charging device and a vehicle charging system capable of quickly charging a vehicle without incurring an increase in equipment cost. It is the purpose.

  In order to solve the above-described problem, the vehicle charging device according to the first invention includes a plurality of connection portions that are either a charging cable connected to the vehicle or an outlet connected to the vehicle via an external charging cable, A charging device for a vehicle that supplies electric power to the vehicle in a state where the vehicle is connected to a connecting portion and charges the vehicle, and is connected to a commercial power source through a single power supply path and supplied from the commercial power source. A power feeding circuit unit that includes a vehicle power feeding path that supplies power to the respective connection units, and a power feeding execution unit that permits or prohibits power feeding to the connection unit for each vehicle power feeding path, and among the connection units The vehicle is connected to a connection detecting means for detecting that the vehicle is connected to the first connecting portion, and to a second connecting portion that is a connecting portion other than the first connecting portion among the connecting portions. The second connection part When the connection detecting means detects that a vehicle is connected to the first connection portion while power is being supplied, the power supply to the second connection portion is prohibited and the first connection is prohibited. Power supply control means for controlling the power supply execution means to permit power supply to the unit.

  According to the present invention, since the power feeding circuit unit is connected to the commercial power source through one power feeding path, power (commercial power) is supplied from the commercial power source to the power feeding circuit unit through the one power feeding path. In this case, unlike the case where a power supply path is provided for each vehicle power supply path of the power supply circuit section (in other words, for each connection section), it is possible to avoid inconveniences such as an increase in equipment cost.

  In addition, when the vehicle is connected to the second connection portion and power is supplied to the second connection portion (that is, when the vehicle is charged through the second connection portion), the first connection is made. When a vehicle is connected to the part, power supply to the second connection part is prohibited and power supply to the first connection part is permitted. That is, charging of the vehicle via the second connecting portion is stopped, and charging of the vehicle via the first connecting portion is started. In this case, since the vehicle is connected to a plurality of connection portions (the first connection portion and the second connection portion), only the vehicle charging via the first connection portion is preferentially performed. Even in a configuration in which power (commercial power) is supplied via the route, it is possible to avoid a reduction in the amount of power supplied to the vehicle (the vehicle connected to the first connection unit). Therefore, in this case, it is possible to quickly charge the vehicle without causing an increase in equipment cost.

  By the way, as a charging mode of the vehicle, there are a private charging that charges at a storage location of the vehicle (for example, a parking lot of a company or a house) and a public charging that charges at a destination of the vehicle. Here, it is conceivable that the vehicle charging device is installed at a storage location of the vehicle and used for private charging, and also opened to the public and used for public charging. In this case, the vehicle that is subject to private charging is parked at the storage location for a long time, whereas the vehicle that is subject to public charging is only temporarily parked, so the first connection portion is used for public charging. It is desirable to use the second connection part for private charging. And when such a use is assumed, it is possible that the frequency which performs vehicle charge (private charge) using a 2nd connection part becomes comparatively high.

  Therefore, in the present invention, in view of this point, the first connection portion is an outlet and the second connection portion is a charging cable. When charging the vehicle using the charging cable, it is only necessary to connect the charging cable to the vehicle, so that the work is easier than when charging the vehicle using the in-vehicle charging cable (outlet). Therefore, when using each connection part properly as mentioned above, it becomes a convenient structure.

  According to a fourth aspect of the present invention, there is provided a vehicle charging apparatus according to any one of the first to third aspects, wherein a plurality of the second connection portions are provided, and a priority order is set in advance for power feeding to each of the second connection portions. The power supply control means supplies power to the plurality of second connection portions in order according to the priority order when a vehicle is connected to any of the plurality of second connection portions among the second connection portions. The power supply executing means is controlled to perform the following.

  According to the present invention, in a configuration in which a plurality of second connection portions are provided, when a vehicle is connected to any of the plurality of second connection portions among the second connection portions, a predetermined priority is set. Since power is supplied to the plurality of second connecting portions in order according to the order, it is possible to quickly charge a vehicle having a high priority.

  In the vehicle charging system according to the fifth aspect of the present invention, a private parking space and a public parking space are provided as parking spaces in which a vehicle can be parked on the premises of a company or a house, and these private parking spaces and public parking spaces are provided. In common, the vehicle charging device according to any one of the first to fourth aspects of the invention is provided, the first connection portion is connected to a vehicle parked in the public parking space, and the second connection portion is The vehicle is connected to a vehicle parked in the private parking space.

  There are cases where private parking spaces and public parking spaces are provided as parking spaces for vehicles in the premises of companies or houses. Private parking spaces are used, for example, to park vehicles owned by residents of houses and employees' vehicles, and public parking spaces are used, for example, to park vehicles for visitors visiting companies or houses. It is done. In the present invention, the private parking space and the public parking space are provided as described above, and the vehicle charging device of the first invention is installed in common to each of the parking spaces. .

  Here, since vehicles parked in public parking spaces (public vehicles) are only temporarily parked, it is required to charge the vehicles promptly, whereas vehicles parked in private parking spaces ( Private vehicles are allowed to be charged over time due to the long parking time. In view of the above, in the present invention, the first connection portion is used for charging a public vehicle, and the second connection portion is used for charging a private vehicle.

The connection detection sensor 38a is a sensor that detects that the vehicle 18a is connected to the first charging cable 22a. The connection detection sensor 38b is a sensor that detects that the vehicle 18b is connected to the second charging cable 22b. The connection detection sensor 38 c is a sensor that detects that the vehicle 18 c is connected to the outlet 23 via the in-vehicle charging cable 26. The connection detection sensor 38c corresponds to a connection detection unit.

  The charging device 20 is provided with a controller 40 as power supply control means. The controller 40 is configured by a known microcomputer having a CPU and the like, and is built in the main body 21. In addition, the controller 40 has a storage unit 40 a for storing various information related to charging of the vehicle 18.

  The controller 40 is connected to the operation unit 33. Here, in this embodiment, when the vehicles 18a and 18b are connected to the charging cables 22a and 22b, respectively, priority is given to power supply regarding which of the charging cables 22a and 22b is supplied with priority. The order can be set by the operation unit 33. That is, it is possible to set which of the vehicles 18a and 18b connected to each of the charging cables 22a and 22b is to be preferentially charged. When the priority of power supply to the charging cables 22 a and 22 b is input by the operation unit 33, the input priority information is input to the controller 40.

Based on the detection results from the connection detection sensors 38a to 38c, the priority order information stored in the storage unit 40a, and the remaining capacity information transmitted from the ECU 41, the controller 40 sets the shut-off devices 37a to 37c. Open / close control. In FIG. 3, for the sake of convenience, the signal lines from the controller 40 to the shut-off devices 37a to 37c are shown as common signal lines, but actually the opening and closing operations to the shut-off devices 37a to 37c are individually controlled. .

  Next, the charging control process executed by the controller 40 will be described. FIG. 4 is a flowchart showing the charging control process. This process is repeatedly executed at a predetermined cycle.

  As shown in FIG. 4, first, in step S11, based on the detection result from the connection detection sensor 38c, it is determined whether or not the vehicle 18c is connected to the outlet 23 via the in-vehicle charging cable 26. If the vehicle 18 is connected to the outlet 23, the process proceeds to step S12.

  In step S12, based on the remaining capacity information of the in-vehicle battery 28 transmitted from the ECU 41 of the vehicle 18c, it is determined whether or not the battery 28 is fully charged. If the in-vehicle battery 28 is not fully charged, the process proceeds to step S13.

  In step S13, it is determined whether or not the vehicle 18a (18b) is being charged through (using) the first charging cable 22a or the second charging cable 22b. Specifically, it is determined whether or not the vehicle 18a (18b) is connected to one of the charging cables 22a and 22b and power is supplied to the connected charging cable 22a (22b). This determination is made based on the detection results of the connection detection sensors 38a and 38b and the open / closed states of the shut-off devices 37a and 37b. If the vehicle 18a (18b) is being charged via the first charging cable 22a or the second charging cable 22b, the process proceeds to step S14. If the vehicles 18a and 18b are not charged via the charging cables 22a and 22b, the process proceeds to step S15.

  In step S14, the charging of the vehicle 18a (18b) through the charging cable 22a (22b) is stopped. In this case, the power supply to the charging cable 22a (22b) is stopped (blocked) by opening the blocking device 37a (37b).

  In step S15, the vehicle 18c is charged via the in-vehicle charging cable 26. In this case, by closing the shut-off device 37c, the power supply to the outlet 23 and the power supply to the in-vehicle charging cable 26 are executed (permitted). Thereby, electric power is supplied from the vehicle-mounted charging cable 26 to the vehicle 18c, and the vehicle-mounted battery 28 is charged. Thereafter, this process is terminated.

  If the vehicle 18c is not connected to the outlet 23 via the in-vehicle charging cable 26 in the previous step S11, the process proceeds to step S17. In step S12, if the in-vehicle battery 28 is fully charged, the process proceeds to step S16, and charging of the vehicle 18c via the in-vehicle charging cable 26 is stopped. In this case, the power supply to the outlet 23 and consequently the in-vehicle charging cable 26 is stopped by opening the shut-off device 37c.

  In continuing step S17, it is determined whether the vehicle 18a is connected to the 1st charge cable 22a based on the detection result from the connection detection sensor 38a. When the vehicle 18a is connected to the first charging cable 22a, the process proceeds to step S18, and it is determined whether or not the in-vehicle battery 28 is fully charged. If the in-vehicle battery 28 is not fully charged, the process proceeds to step S19.

  In step S19, it is determined whether or not the vehicle 18b is being charged through (using) the second charging cable 22b. Specifically, it is determined whether or not the vehicle 18b is connected to the second charging cable 22b and power is supplied to the second charging cable 22b. This determination is made based on the detection result of the connection detection sensor 38b and the open / closed state of the blocking device 37b. If the vehicle 18b is being charged via the second charging cable 22b, the process proceeds to step S20. If the vehicle 18b is not charged via the second charging cable 22b, the process proceeds to step S21.

  In step S20, the charging of the vehicle 18b via the second charging cable 22b is stopped. In this case, the power supply to the second charging cable 22b is stopped by opening the blocking device 37b.

  In step S21, the vehicle 18a is charged via the first charging cable 22a. In this case, power supply to the first charging cable 22a is performed by closing the shut-off device 37a. Thereby, electric power is supplied from the first charging cable 22a to the vehicle 18a, and the in-vehicle battery 28 is charged. Thereafter, this process is terminated.

  According to the above steps S19 to S21, when the vehicles 18a and 18b are connected to the charging cables 22a and 22b, respectively, the charging of the vehicle 18a through the first charging cable 22a causes the second charging cable 22b to be charged. This is prioritized over the charging of the vehicle 18b. As described above, in the present embodiment, since the power supply priority is set so that power is supplied in preference to the first charging cable 22a among the charging cables 22a and 22b, based on the priority, Such priority charging is performed.

  If the vehicle 18a is not connected to the first charging cable 22a in the previous step S17, the process proceeds to step S24. In step S18, if the in-vehicle battery 28 is fully charged, the process proceeds to step S23, and charging of the vehicle 18a through the first charging cable 22a is stopped. In this case, the power supply to the first charging cable 22a is stopped by opening the blocking device 37a.

  In continuing step S24, it is determined whether the vehicle 18b is connected to the 2nd charge cable 22b based on the detection result from the connection detection sensor 38b. When the vehicle 18b is not connected to the second charging cable 22b, this process is terminated. If the vehicle 18b is connected to the second charging cable 22b, the process proceeds to step S25, and it is determined whether or not the in-vehicle battery 28 is fully charged. If the in-vehicle battery 28 is not fully charged, the process proceeds to step S27.

  In step S27, the vehicle 18b is charged via the second charging cable 22b. In this case, power supply to the second charging cable 22b is executed by closing the shut-off device 37b. As a result, electric power is supplied from the second charging cable 22b to the vehicle 18b, and the in-vehicle battery 28 is charged. Thereafter, this process is terminated.

  If the in-vehicle battery 28 is fully charged in step S25, the process proceeds to step S26, and the charging of the vehicle 18b via the second charging cable 22b is stopped. In this case, the power supply to the second charging cable 22b is stopped by opening the blocking device 37b. Thereafter, this process is terminated.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  In the charging device 20, since the power supply line 36 is connected to the distribution board 14 via one power wiring 16 (single circuit), each branch power supply line 36 a to 36 b (that is, each charging cable 22 a, 22 b and outlet 23). Unlike the case where power wiring is individually provided (assigned), inconveniences such as an increase in equipment cost can be avoided.

  Further, the connection detection sensor 38c indicates that the vehicle 18c is connected to the outlet 23 via the in-vehicle charging cable 26 while the vehicles 18a and 18b are being charged (powered) via the charging cables 22a and 22b. When it is detected by the above, the shut-off devices 37a to 37c are controlled to be opened and closed so as to prohibit the power supply to the charging cables 22a and 22b and to permit the power supply to the outlet 23. That is, control was performed so that charging to the vehicles 18a and 18b via the charging cables 22a and 22b was stopped and charging to the vehicle 18c via the outlet 23 (and the in-vehicle charging cable 26) was started. In this case, since the vehicle 18 is connected to the plurality of connecting portions 22 and 23 (the charging cable 22 and the outlet 23), only the vehicle charging through the outlet 23 is preferentially performed. Even in a configuration in which power (commercial power) is supplied via 16, it is possible to avoid a reduction in the amount of power supplied to the vehicle 18c (the vehicle 18c connected to the outlet 23). Therefore, in this case, it is possible to quickly charge the vehicle 18 without causing an increase in equipment cost or the like.

  Since the first connecting portion is the outlet 23 and the second connecting portion is the charging cable 22, it is possible to easily determine which of the connecting portions is the first connecting portion. Therefore, it can be said that this is a practically preferable configuration for implementing the above-described invention in which charging of the vehicle 18 is preferentially performed using the first connection portion (outlet 23).

  Priorities are set for power feeding to the charging cables 22a and 22b, and when the vehicles 18a and 18b are connected to the charging cables 22a and 22b, the charging cables 22a are sequentially arranged according to the set priorities. , 22b is controlled to open and close so as to supply power to 22b. In this case, it is possible to quickly charge the vehicle 18a having a high priority.

  Of the parking spaces 19a to 19c, the vehicle 18c parked in the visitor parking space 19c (in other words, a public vehicle) is only temporarily parked, so that the vehicle 18 needs to be charged quickly. On the other hand, the vehicles 18a and 18b parked in the employee parking spaces 19a and 19b (in other words, private vehicles) are allowed to be charged over time because the parking time is long. Therefore, in the above embodiment, in view of this point, the outlet 23 (first connecting portion) is used for charging the customer's vehicle 18c, and the charging cable 22 (second connecting portion) is used for charging the employees' vehicles 18a and 18b. It was made to use for. In this case, suitable vehicle charging can be realized in consideration of the parking mode between the visitor vehicle 18c and the employee vehicles 18a and 18b.

  Further, the charging cable 22 is used to charge the employees' vehicles 18a and 18b, and the outlet 23 is used to charge the visitor vehicle 18c. When charging the vehicle using the charging cable 22, it is only necessary to connect the charging cable 22 to the vehicle 18. Therefore, the operation is easier than when charging the vehicle using the in-vehicle charging cable 26 (outlet 23). is there. Therefore, it can be said that this configuration is convenient for employees who are considered to have relatively many opportunities to charge the vehicles 18a and 18b.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  In the above embodiment, the outlet 23 is used as the first connection portion and the charging cable 22 is used as the second connection portion. However, the charging cable 22 is used as the first connection portion in reverse, and the second connection portion is used. As an alternative, the outlet 23 may be used. Also in this case, since it is possible to easily determine which of the connecting portions is the first connecting portion, it is practically preferable to preferentially charge the vehicle 18 using the first connecting portion. It becomes composition.

  Moreover, both the 1st connection part and the 2nd connection part are good also as the electrical outlet 23, or good also as the charging cable 22. FIG.

  In the above embodiment, two charging cables 22 (second connecting portions) are provided, but three or more charging cables 22 may be provided. Further, only one charging cable 22 may be provided. In this case, among the insertion holes 34 of the charging cable 22 provided in plural (specifically, two) on the front surface portion 21a of the main body 21, some of the insertion holes 34 are unused, and thus The insertion hole 34 to be used is preferably closed by attaching a cover or the like. Then, when newly adding the charging cable 22, the cover is removed from the insertion hole 34 and the charging cable 22 may be pulled out through the insertion hole 34.

  In the above embodiment, when the vehicles 18a and 18b are connected to the charging cables 22a and 22b, respectively, power is supplied to the charging cables 22a and 22b in order according to preset power supply priority. For example, power supply to the charging cables 22a and 22b may be performed simultaneously without setting the priority order. In other words, the vehicles 18a and 18b may be charged simultaneously. In this case, the shut-off devices 37a and 37b are both closed.

  -In above-mentioned embodiment, although the charging device 20 was installed in the parking lot 13 provided in the site 11 of a company, you may install the charging device 20 in the parking lot provided in the site of a house. In the parking lot of the house, as a parking space for vehicles, a parking space for residents (equivalent to a private parking space) for parking vehicles owned by the residents of the housing and a vehicle for visitors visiting the housing There are cases where there are parking spaces for visitors (corresponding to public parking spaces). In this case, it is conceivable to install the charging device 20 in common for the resident parking space and the visitor parking space. And the charging cable 22 (2nd connection part) of the charging device 20 is used for charge of the parking vehicle of a resident parking space, and the outlet 23 (1st connection part) is charged of the parking vehicle of a visitor parking space. It can be considered to be used for this.

  Here, since vehicles (public vehicles) parked in the visitor parking space are only temporarily parked, it is required to charge the vehicle promptly, whereas they are parked in the resident parking space. The vehicle (private vehicle) to be charged is allowed to be charged over time because the parking time is long. For this reason, if it is set as the above structures, the suitable vehicle charge which considered each parking form with a resident's vehicle and a visitor's vehicle is realizable.
