Description

  The present invention relates to an electric vehicle charging apparatus, an electric vehicle charging system, an electric vehicle charging method, a program, and a recording medium that supply electric power for charging an electric vehicle battery, for example, at a charging station.

  In recent years, an electric vehicle using a motor as a power source instead of an internal combustion engine has been developed. An electric vehicle uses a storage battery as a power source and travels by driving a motor by supplying power from the storage battery. For this reason, compared with an internal combustion engine, it has many advantages such as low energy cost, high energy efficiency, extremely low noise, and no exhaust gas when traveling.

  On the other hand, as one of the problems of an electric vehicle, there is a problem that a travelable distance is short when the energy is fully charged (storage battery is fully charged) as compared with a vehicle using an internal combustion engine (for example, a gasoline vehicle). For this reason, when going out with an electric vehicle, charging at a charging station is required.

  Here, the charging station is charged for charging the electric vehicle. Regarding this charging, for example, Patent Document 1 describes charging for a substantial charge output power amount of a storage battery. Specifically, replace the used standardized exchange type storage battery with a charged one, and charge the amount of power obtained by subtracting the input power amount from the charge output power amount of the used standardized exchange type storage battery, and Users are charged for fees for exchanges and other charges. The input electric energy is electric energy input (charged) by a regenerative brake of an electric vehicle or a household power source.

Thus, the operation of the power output device 16 is controlled. Thereby, the charge operation with respect to the storage battery 26 of the electric vehicle 101 is started (S19).

  Thereafter, when the charging of the storage battery 26 is completed (S20), the power supply control unit 15 ends the power supply from the power output device 16 to the electric vehicle 101. Thereby, the charge operation with respect to the storage battery 26 of the electric vehicle 101 is complete | finished (S21).

  Here, the power supply control unit 15 determines that the charging is completed when the supply of the charging output power amount calculated by the power amount calculation unit 14 from the power output device 16 to the electric vehicle 101 is completed in S20. To do. Regarding the determination of the completion of the charging in S20, it is confirmed that the battery output amount calculated by the power amount calculation unit 14 is charged in the storage battery 26 in the battery remaining amount measurement unit 23 of the vehicle side system 2. In such a case, the charging may be completed.

  Further, when the charging operation is finished in S21, the power supply control unit 15 transmits the information to the display control unit 17 of the station side system 1 and the display control unit 37 of the vehicle side system 2. The display control unit 17 causes the display device 11 to display that the charging of the storage battery 26 is completed based on the information on the end of the charging operation from the power supply control unit 15. The charging completion is also notified to the user by sound from a speaker (not shown) (S22).

  Thereafter, when the charging cable 3 is disconnected from the electric vehicle 101 (S23), the station side system 1 ends the operation.

  Next, the operation of the automobile side system 2 will be described. In FIG. 3, in the vehicle side system 2, the electric vehicle 101 is parked at the charging station, and the charging cable 3 is connected to the electric vehicle 101 by the user. When this state is detected (S31), The battery remaining amount information of the storage battery 26 is provided from the battery remaining amount measuring unit 23 to the station side system 1 according to a request or a preset setting. Moreover, the power consumption rate information of the electric vehicle 101 is provided from the power consumption rate calculation unit 22 (S32).

  Next, when receiving the travelable distance information from the travelable distance calculating unit 13 of the station side system 1, the display control unit 37 displays the travelable distance on the display device 31 based on the information. The travelable distance is also notified to the user by sound from a speaker (not shown) (S33).

  Next, the power supply unit 25 receives power supply from the power output device 16 of the station-side system 1 and starts a charging operation for the storage battery 26 (S34). The charging operation to the storage battery 26 by the power supply unit 25 is monitored by the charge control unit 24. Further, the transition of the remaining amount due to the charging of the storage battery 26 is appropriately measured by the battery remaining amount measuring unit 23 from the start of charging to the completion of charging. The measurement result is transmitted to the travelable distance calculation unit 13 and stored in the history information storage device 36.

  Thereafter, when the charging of the storage battery 26 is completed, the power supply from the power output device 16 of the station side system 1 is stopped, and at the same time, from the power supply control unit 15 of the station side system 1 to the charge control unit 24 of the vehicle side system 2. The completion of charging is notified (S35). Accordingly, the power supply unit 25 finishes the charging operation for the storage battery 26 (S36).

  Next, when the display control unit 37 receives a notification of the end of the charging operation from the power supply control unit 15 of the station side system 1, the display control unit 37 displays on the display device 31 that the charging of the storage battery 26 has been completed. The charging completion is also notified to the user by sound from a speaker (not shown) (S37).

  Thereafter, when the charging cable 3 is disconnected from the electric vehicle 101 (S38), the vehicle-side system 2 ends the operation.

  As described above, in the electric vehicle charging system according to the present embodiment, the station-side system 1 calculates the amount of power supplied to the storage battery 26 according to the amount of money received from the user, and the amount of supplied power and the remaining amount of storage battery. Thus, the travelable distance of the electric vehicle 101 is calculated, and the calculated travelable distance is displayed on at least the display device 11 of the station side system 1.

  Therefore, the user can know the travelable distance according to the remaining battery level and the amount of money deposited with reference to the display on the display device 11. This allows the user to charge only the mileage necessary to reach the home, for example, at a charging station where the electricity charges are high, and to charge further charges at a low price at home, such as late-night charges. Can be done. Further, in the charging station, if the unit of receipt of the amount deposited in advance from the fee intake 111 is set to a unit such as 500 yen, 100 yen, or 10 yen, the charging process and the charge settlement process are performed. Simplification can be achieved.
