  In addition, when requested by the control unit 13, the control unit 23 acquires ID information or the like from the storage unit 24 and outputs the ID information or the like to the control unit 13 via a wire or wirelessly.

  Next, operation | movement of the electric power feeder 1 which is embodiment which concerns on this invention is demonstrated using FIG. FIG. 2 is a flowchart illustrating an example of processing of the power supply apparatus 1 in the present embodiment.

  The charge amount charging system S and the power supply apparatus 1 as the embodiment of the present invention are configured as described above, and are controlled according to the following procedure.

  Specifically, as illustrated in FIG. 2, first, after the charger 25 is set, the control unit 13 of the power supply device 1 controls power supply to the power receiving device 2 in step S <b> 11. And the control part 13 acquires the information regarding the charger 25, for example, ID information etc., such as whether it has contracted. Then, after acquiring the ID information and the like, the control unit 13 proceeds to step S12.

  In step S <b> 12, the control unit 13 determines whether it is possible to supply power to the power receiving device 2. Specifically, the authentication unit 14 outputs ID information or the like registered in the authentication unit 14 in advance to the control unit 13, and the control unit 13 receives the ID information and the like and transmits it from the control unit 23. It is determined whether or not the ID information etc. matched.

  When the control unit 13 determines that power cannot be supplied to the power receiving device 2, that is, the ID information recorded in the storage unit 24 and the ID information registered in the authentication unit 14 in advance match. When it is determined that there is not (step S12; NO), the control unit 13 outputs a control signal for stopping charging to the power source unit 11, and the process proceeds to step S19.

  In step S <b> 19, the control unit 13 displays an error message indicating that the power receiving device 2 cannot supply power on a display unit (not shown) that is a display unit of the system S.

  On the other hand, when the control unit 13 determines that power can be supplied to the power receiving device 2, that is, the ID information recorded in the storage unit 24 and the ID information registered in the authentication unit 14 in advance are one. If it is determined that it has been performed (step S12; YES), the control unit 13 outputs a control signal not permitting charging to the power supply unit 11 and proceeds to step S13.

  In step S13, based on an instruction from the user, for example, when the power supply device 1 side is 3V, the control unit 13 needs to set the power reception device 2 side to 3V, and the power reception device 2 side normally supplies power. The wattmeter is set to determine whether the payment is made or not, and the payment method is selected such as whether the fee is paid by cash or by a prepaid card. Then, after the setting of both power meters and the selection of the fee payment method are completed, the process proceeds to step S14.

  In step S14, the control unit 13 starts to supply power to the power receiving device 2, and then proceeds to step S15.

  In step S15, the control unit 13 compares the supply amount detected by the current accumulator (or wattmeter) 12 with the charge amount indicated by the charge amount information acquired by the control unit 23, and the control unit 13 After comparing the supply amount of power and the charge amount, the process proceeds to step S16.

  In step S <b> 16, the control unit 13 determines whether the power receiving device 2 is normally supplied with power. Specifically, it is determined whether the difference between the supply amount and the charge amount is within a predetermined value as a result of comparison between the supply amount of power and the charge amount. When the difference between the supply amount detected by the current accumulator (or wattmeter) 12 and the charge amount indicated by the charge amount information acquired by the control unit 23 is equal to or greater than a predetermined value, the control unit 13 (Step S16; NO), an error message indicating that power supply has not been normally performed is displayed on a display unit (not shown) which is a display means of the system S (Step S19).

  On the other hand, when the control unit 13 determines that the power is normally supplied as a result of the power supply to the power receiving device 2, that is, the supply amount detected by the current accumulator (or wattmeter) 12 and the control unit 23 acquire the supply amount. If the difference from the charge amount indicated in the charge amount information is within a predetermined value (step S16; YES), the process proceeds to step S17.

  In step S <b> 17, the control unit 13 determines whether or not to end the power supply by detecting the user's operation instruction or the secondary battery 26 being fully charged, and determines not to end the power supply. In that case (step S17; NO), the processing from step S15 is repeated.

  On the other hand, when it determines with the said electric power feeding complete | finishing the control part 13 (step S17; YES), it transfers to step S18.

  In step S <b> 18, the control unit 13 determines to perform charging, outputs a charging command to the charging unit 15, and the processing of the power supply apparatus 1 ends. When an error is displayed on a display unit (not shown) that is a display unit of the system S (step S19), the control unit 13 determines not to charge, and the processing of the power supply apparatus 1 ends.

  Based on the charging command, the charging unit 15 performs charging according to the amount of charge.

  As described above, in the charge amount charging system S, the supply amount detected by the current integrator (or wattmeter) 12 and the charge amount indicated in the charge amount information acquired by the control unit 23 can be confirmed. Therefore, it is possible to charge according to the amount of charged electric power, and it is possible to prevent useless charges, useless charging and wasted time.

  Further, by comparing the supply amount detected by the current accumulator (or wattmeter) 12 with the charge amount indicated by the charge amount information acquired by the control unit 23, the charging efficiency is known, and a warning or stop is performed. It becomes possible.

  Further, illegal modification or the like on the power receiving apparatus 2 side can be performed by comparing the supply amount detected by the current accumulator (or wattmeter) 12 with the charge amount indicated by the charge amount information acquired by the control unit 23. It becomes possible to prevent.

  In the present embodiment, the contact unit 21, the current accumulator (or wattmeter) 22, the control unit 23, and the storage unit 24 in the power receiving device 2 have been described as being provided, but they may be retrofitted instead of being provided. .
