Description

  The present invention relates to a power supply control device for supplying electric power to an electric vehicle or the like.

In recent years, hybrid vehicles have attracted attention as environmentally friendly vehicles, and hybrid vehicles are actually sold by many manufacturers. In addition, a so-called electric vehicle that drives a vehicle with electric power charged in a battery has been studied as a next-generation vehicle, and many technologies related to this electric vehicle have been disclosed in public patents.

  For example, in Patent Document 1, when a car door lock mechanism is switched from an unlocked state to a locked state in order to prevent the charging cable from being stolen, the connector lock mechanism and the cover lock mechanism are unlocked in conjunction therewith. A technique for switching from a state to a locked state is disclosed.

JP 2009-81917 A

  In the technique described in Patent Document 1, since no locking mechanism is provided on the household outlet side, there arises a problem that another person steals power from the household outlet.

The present invention is for solving such a problem, and the invention according to claim 1 is directed to a commercial power source, an outlet connected to the commercial power source, and whether power is supplied from the commercial power source to the outlet. A switching unit capable of switching whether or not, a receiving unit for receiving a signal for turning on / off a car door lock, and an input unit for inputting a personal identification number, the switching unit, When the receiving unit receives a signal for turning on the door lock of the car in a state where power from the commercial power source is prohibited to be supplied to the outlet, the switching unit receives power from the commercial power source. If the password input operation is performed from the input unit until the receiving unit receives a signal for turning on the door lock of the car, the switching unit is connected from the commercial power source to the outlet. Power to And wherein the sea urchin switched.
The invention according to claim 2 includes: a commercial power source; an outlet connected to the commercial power source; a switching unit capable of switching whether to supply power from the commercial power source to the outlet; and a door lock of the car. A receiving unit for receiving a signal for turning on / off, an input unit for inputting a personal identification number, and a storage unit for storing the personal identification number and information on a signal for turning on a vehicle door lock in association with each other; And the switching unit prohibits supplying power from the commercial power source to the outlet, and the receiving unit receives a signal for turning on the door lock of the car, and If a password is input from the input unit, the switching unit may supply power from the commercial power source to the outlet if the input password corresponds to a signal for turning on the door lock. It is characterized by supplying to .

  According to the present invention, it is possible to supply power to the outlet only when the received signal for turning on the door lock and the input personal identification number are associated with each other. It is possible to stop the car and prevent the power from being stolen from the outlet.

It is a perspective view of an example using the example device formed by applying the present invention. It is a block diagram of a present Example apparatus. It is a storage form figure of the memory | storage part. It is a flowchart of a present Example.

Next, a charging control apparatus according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a garage in which the apparatus of this embodiment is mounted. The apparatus according to the present embodiment is equipped with an outlet 18, and the car 100 parked in the garage is connected to the outlet 18 by connecting a charging cable (not shown) to the rechargeable battery (see FIG. (Not shown) can be charged. Further, the user 200 can turn on / off (release) the lock of the door of the car 100 by operating the intelligent key 300 and can prohibit / permit the power supply from the outlet 18. Is possible.

  FIG. 2 is a block diagram of the charging control device of the present embodiment. 2 is embedded in the wall provided with the outlet 18 of FIG. 1 (however, the operation unit 13, the display unit 12, the outlet 18, and the receiving unit 15). Is not filled).

  In FIG. 2, the control unit 11 controls each block. The display unit 12 includes, for example, a liquid crystal display device, and displays an instruction to input the current time and password, a time required for charging, a capacity of a car battery, and the like. The operation unit 13 has keys for setting and inputting a password.

  The storage unit 14 is composed of, for example, a flash memory, and stores a control program for operating the control unit 11, a password, and the like. Further, as shown in FIG. 3, the storage unit 14 stores a password and a charging time zone in association with each family member.

  The receiving unit 15 receives and demodulates the radio wave transmitted from the intelligent key. The receiving unit 15 may have a function of receiving and demodulating infrared rays instead of radio waves.

  The switching unit 17 has a function of switching based on the control of the control unit 11 so that the power from the commercial power supply 16 is supplied to the outlet 18 or not. The outlet 18 is an outlet normally used in a general household.

  Next, an embodiment to which the present invention is applied will be described with reference to the flowchart of FIG. FIG. 4 is a flowchart showing the operation of the apparatus of this embodiment.

  In step S11 of FIG. 4, it is assumed that the control unit 11 is in a charging prohibited state. That is, the control unit 11 controls the switching unit 17 so that power from the commercial power supply 16 is not supplied to the outlet 18.

  In the subsequent step S12, when the control unit 11 determines that the reception unit 15 has received a signal for instructing door lock from the intelligent key 300, the control unit 11 proceeds to step S14, and otherwise proceeds to step S13.

  In step S13, if the control unit 11 determines that there is an input operation of a password (for example, a four-digit number) from the operation unit 13, the process proceeds to step S14. Otherwise, the process proceeds to step S12. return.

  In step S14, the control unit 11 determines whether or not a predetermined condition is satisfied. Specifically, the control unit 11 compares the password entered in step S13 with the current time. For example, if it is determined that the password “1234” is input, it is determined whether or not the current time is 19:00 to 23:00, and it is determined that the current time is between 19:00 and 23:00. If so, the process proceeds to step S15; otherwise, the process returns to step S11.

  In step S <b> 15, the control unit 11 controls the switching unit 17 to supply power from the commercial power supply 16 to the outlet 18. At this time, the vehicle 100 and the outlet 18 are electrically connected by a cable (not shown).

  In the subsequent step S16, if the control unit 11 determines that a battery (not shown) mounted on the vehicle 100 is fully charged, the process proceeds to step S17, and if not, the process proceeds to step S08.

  In step S17, the control unit 11 controls the switching unit 17 to stop power supply from the commercial power supply 16 to the outlet 18, and returns the process to step S01.

  In step S18, if the control unit 11 determines that a cable (not shown) has been disconnected, the process proceeds to step S17, and otherwise returns to step S16. Note that the determination of whether or not the cable has been disconnected may be made, for example, by determining that the cable has been disconnected when it is detected that the outlet 18 side has been opened in a circuit.

  As described above, in the present embodiment apparatus, it is possible to perform charging using an outlet by inputting a personal identification number without receiving a door lock signal. For this reason, for example, even if the user loses the intelligent key and turns on / off the door lock of the car using a normal key, the user can charge the battery using the outlet.
