The indicator lamp 36 is a light-emitting display device that is turned on or blinked according to the state of charging of the automobile 40. For example, the indicator lamp 36 lights up in a different manner during charging standby, during charging, and when charging is completed. Alternatively, the indicator lamps 36 are lit in different emission colors when waiting for charging, during execution of charging, and when charging is completed. Thereby, the user can easily know the charging status of the automobile 40.

  The vehicle 40 is a so-called plug-in hybrid vehicle (PHV), which includes an engine as a power source, a motor generator (both not shown), and the like, and an in-vehicle battery 41 made of a high-voltage secondary battery. Further, the automobile 40 is provided with a power input terminal 42 for taking in electric power from the outside. Therefore, the in-vehicle battery 41 is appropriately charged with the regenerative power of the motor generator while the vehicle is running, and is charged with the power from the external power source supplied via the power input terminal 42 when the vehicle is stopped. It has become. For example, when the connection plug 34 of the charging cable 33 is inserted into the power input terminal 42 while the vehicle is parked in the parking space 29, shared power or the like is supplied from the charging device 31 to the automobile 40 via the charging cable 33. The battery 41 is charged.

  The automobile 40 is provided with an ECU (electronic control unit, hereinafter referred to as an in-vehicle ECU) 43 that manages the storage state of the in-vehicle battery 41 and a communication device 44 that performs wireless communication with an external device. The in-vehicle ECU 43 sequentially calculates the remaining capacity (SOC) of the in-vehicle battery 41 and transmits the remaining capacity information by the communication device 44 in response to a request from an external device.

  The vehicle 40 may be an electric vehicle (EV) including an electric motor as a power source. The electric vehicle is also of a plug-in type, and includes the in-vehicle battery 41, the power input terminal 42, the in-vehicle ECU 43, and the communication device 44 as described above.

  Next, the electrical configuration of the parking system will be described with reference to FIG. In particular, here, a configuration relating to charge management control performed with the charge management device 22 as a center will be described.

  The charge management device 22 includes a controller 51 including a known microcomputer having a CPU, an operation device 52 including a character input keyboard and input buttons, a display device 53 including a liquid crystal display, and an external device. And a communication device 54 that performs wireless communication between the controller 51 and the controller 51. An operation device 52, a display device 53, and a communication device 54 are connected to the controller 51. In addition, the controller 51 includes a storage device 51a including a RAM or the like that stores various data related to charge management for the in-vehicle battery.

  The controller 51 obtains a request acquisition function for acquiring a charging request on the user side for each parking space 29 (charging device 31), a charging condition setting function for setting a charging condition on the power feeding side including a suppliable power amount, and acquisition of a charging request. An embodiment setting function for setting an embodiment of charging based on a charging request and a charging condition is sometimes provided. Details will be described.

  When an input operation such as a charge reservation is performed on the operation device 52 by a user (resident or the like), the user operation information is input to the controller 51. The user operation information related to the charge reservation includes a parking position number, a personal identification number, a desired charge date and time, a charge amount (or charge time), and the like. This user operation information corresponds to a “charge request”. When the controller 51 acquires user operation information from the operation device 52, the controller 51 creates charge reservation data (corresponding to charge reservation information) based on the user operation information. This charge reservation data is schedule data in which user operation information (charge requests) from a plurality of users is gathered in time series, and the amount of power that can be supplied from the power storage device 21 (shared battery 21a) or the shared distribution board 14 It is created according to the charging conditions each time including (suppliable electric energy) and the like. The charging reservation data is stored in the storage device 51a every time it is created.

  Among the charge reservation data stored in the storage device 51 a, at least information related to the reserved time zone is read out in response to a request from the user and displayed on the display device 53. As a result, the user can operate the operation device 52, that is, make a charge reservation while confirming the degree of congestion of the charge reservation. Note that even the charge reservation data once stored in the storage device 51a can be changed in response to a user rewrite request.

  Further, the communication device 54 can wirelessly communicate with the terminal device 18 such as a personal computer owned by each household of the apartment house 10, and charging reservation by the terminal device 18 is also possible. That is, when an input operation such as a charge reservation is performed by a user (such as a resident) using the terminal device 18, the user operation information is input to the controller 51, and charge reservation data is created based on the user operation information. The In the terminal device 18, the stored charge reservation data can be read from the storage device 51a and displayed on the display.

  The electricity storage device 21 is provided with an electricity storage amount detection sensor 21b that detects the amount of electricity stored in the shared battery 21a, and the detection result of the electricity storage amount detection sensor 21b is input to the controller 51. The controller 51 calculates the storage amount of the shared battery 21a based on the detection result of the storage amount detection sensor 21b. For example, when creating the charge reservation data, the controller 51 grasps the power supply capability (suppliable power amount) each time based on the amount of power stored in the shared battery 21a, and creates the charge reservation data within the range of the power supply capability.

  The charge management device 22 is provided with a power switching device 56. The power switching device 56 charges any of the two systems of power supplied to the charge management device 22 (that is, shared power from the shared distribution board 14 and battery stored power from the power storage device 21) to the in-vehicle battery 41. And is connected to the shared distribution board 14 via the power line 17 and connected to the shared battery 21 a of the power storage device 21 via the power line 27. In other words, when the power switching device 56 is switched, any one of the shared power from the shared distribution board 14 and the battery stored power from the power storage device 21 is connected to each charging device 31 via the power line 32, and each It is supplied to the vehicle battery 41 of the automobile 40. It is also possible to adopt a configuration in which both the shared power from the shared distribution board 14 and the battery stored power from the power storage device 21 are supplied to each charging device 31 at the same time.

Here, the two systems of power supplied to the charge management device 22, that is,
(1) Shared power supplied from the shared distribution board 14
(2) The battery stored power supplied from the power storage device 21 has a different power unit price, and (2) has a lower power unit price. This is because the power of (2) is stored by nighttime power with a low power unit price or solar power generation of the solar panel 25 (here, (1) assumes daytime power. ) In the present embodiment, the in-vehicle battery 41 is basically charged with the electric power of (2), and the in-vehicle battery 41 is charged with the electric power of (1) when the electric power of (2) is insufficient. It is said. That is, the battery stored power supplied from the power storage device 21 is preferentially used when charging the in-vehicle battery 41. The power switching device 56 described above switches the supplied power.

  The controller 51 is electrically connected to each charging device 31, and a detection result is input from a connection detection sensor 35 provided in each charging device 31. The controller 51 determines the presence / absence of a vehicle to be charged and the connection with the vehicle based on the detection result of the connection detection sensor 35. And when the vehicle used as charge object exists and the connection with the vehicle is made, charge of the vehicle-mounted battery 41 is performed based on the charge reservation data memorize | stored in the memory | storage device 51a.

  When charging the in-vehicle battery 41, the controller 51 performs charging by the charging device 31 (power feeding to the in-vehicle battery 41) while monitoring the remaining capacity (SOC) of the in-vehicle battery 41. More specifically, the controller 51 transmits a request signal to the in-vehicle ECU 43 at a predetermined cycle by the communication device 54 when charging the in-vehicle battery 41, and the in-vehicle ECU 43 responds to the request signal with the request signal. The remaining capacity information of is transmitted. Then, the controller 51 receives the remaining capacity information transmitted from the in-vehicle ECU 43 and acquires the remaining capacity of the in-vehicle battery 41.

  When charging the in-vehicle battery 41, the in-vehicle ECU 43 is temporarily activated even when the user is absent, so that the remaining capacity can be calculated. Further, the charge management device 22 and the in-vehicle ECU 43 may be configured to be capable of wired communication, and the remaining capacity information may be communicated by wired communication. For example, the remaining capacity information is communicated using the power line 32 that connects the charging management device 22 and the charging device 31 and the charging cable 33 that connects the charging device 31 and the automobile 40. However, it is also possible to adopt a configuration in which the remaining capacity information is not transmitted from the in-vehicle ECU 43 to the charge management device 22.

  Moreover, the controller 51 implements lighting control of the indicator lamp 36 for the charging device 31 in the parking space where the charging reservation has been made. At this time, for example, the controller 51 changes the indicator lamp 36 in a different manner depending on whether charging is in progress (from reservation completion to charge execution), charge execution (from charge start to charge end), or charge completion. Light up. In addition, the structure which lights the indicator lamp 36 only at the time of charge execution and charge completion may be sufficient.

  Further, the controller 51 is connected to the management computer 62 of the management company that manages the apartment house 10 via the Internet 61. After charging the automobile 40, the controller 51 calculates a charging fee based on the charging information stored in the storage device 51a, and transmits the calculated charging fee information to the management computer 62 of the management company.

  Next, a control process executed by the controller 51 of the charge management device 22 will be described. Here, a reservation control process when the user makes a charge reservation and a charge control process when the vehicle-mounted battery 41 is charged based on the reservation information reserved for charge will be described.

  First, the reservation control process will be described based on the flowchart shown in FIG. This process is executed by the controller 51 with the start of operation of the operation device 52 by the user (for example, operating a reservation start button) as a trigger.

  First, in step S11, it is determined whether a parking position number (for example, the number of the parking space 29) and a personal identification number are input by the user. When the parking position number and the password are input, the process proceeds to step S12. When the parking position number and the password are not input, the process returns to step S11, and whether or not they are repeatedly input until they are input. Judgment.

  In step S12, it is determined whether or not the password entered in step S11 matches the password registered in advance in the controller 51 (for example, the storage device 51a). If the entered personal identification number matches the registered personal identification number, the process proceeds to step S13, and if not, the present process is terminated. Thereby, it can prevent that charge reservation is performed by persons other than the resident of the housing complex 10. FIG.

  In step S13, the charge reservation data stored in the storage device 51a is read out. Specifically, the charge reservation data of all the cars 40 that have already been reserved for charging at the current (reservation) time are read out.

  In step S14, the storage amount (current storage amount Q1) of the storage device 21 (shared battery 21a) at the present time is calculated based on the detection result of the storage amount detection sensor 21b.

  In step S15, based on the charge reservation data acquired in steps S13 and S14 and the current power storage amount Q1, the estimated power storage amount (estimated power storage amount Q2) of the power storage device 21 is set as the supplyable power amount that can be supplied in the future. Calculate for each. The estimated power storage amount Q2 corresponds to the suppliable power amount of the shared battery 21a. In the present embodiment, the estimated power storage amount Q2 is calculated from the balance of the power amount in the shared battery 21a. More specifically, the estimated charged amount Q2 after α days is calculated based on the following equation (1).

Q2 = Q1 + α · DS (1)
D is a storage amount (default value) stored in the shared battery 21a using night power during one day (specifically, at night time), and S is reserved for charging from the present time to α days later. It is the total amount (predicted value) of the stored electric power supplied from the shared battery 21a to the in-vehicle battery 41 of all automobiles 40 being connected.

  Here, it is assumed that the on-vehicle battery 41 is charged by supplying power from the shared battery 21a. It is also possible to calculate the estimated storage amount Q2 taking into account that the shared battery 21a is charged by solar power generation of the solar panel 25.

In step S16, the charging price at each date and time is calculated based on the estimated power storage amount Q2 calculated in step S15. As described above, since the shared power (daytime power) supplied from the shared distribution board 14 and the battery stored power supplied from the power storage device 21 have different power unit prices, the charging price differs depending on which one is used, The latter one (relatively cheap power) is preferentially used. Therefore, in the present embodiment, based on the estimated storage amount Q2 after α days,
(A) A period in which the in-vehicle battery 41 is charged with the stored power (relatively cheap power) of the shared battery 21a,
(B) A period in which the in-vehicle battery 41 is charged with shared power (relatively expensive power) supplied from the shared distribution board 14;
(C) The period when the vehicle-mounted battery 41 is charged with both of these electric powers is calculated. And the charge price in each date is calculated by these (a)-(c).

  Thereafter, in step S17, based on the charge reservation data acquired in step S13, the estimated storage amount Q2 calculated in step S15, and the charge price calculated in step S16, the current charge reservation status and the charge price at each date and time And the estimated power storage amount Q2 are displayed on the display device 53. Thereby, the user can make a charge reservation by referring to the charge reservation status, the charge price, and the estimated power storage amount Q2.

  In this way, when various information related to the charge reservation (the state of charge reservation, the charge price at each date and the estimated power storage amount Q2) is displayed on the display device 53, the user performs an input operation of the charge reservation while looking at the display device 53. To do. At this time, the operation device 52 is operated to input a desired charging date and time, to select a full charge / time specified charge mode, and to add a limited charge charge (these also correspond to charge requests). Here, when full charge is selected as the charge mode, charging is performed until the in-vehicle battery 41 is fully charged. When time-designated charge is selected as the charge mode, charging is performed for the time specified by the user. Is done. When the user selects time-designated charging, the charging designation time (required power supply time as a required power supply parameter) is also input.

  In addition, when limited charging is added, the on-board battery 41 is charged using only the stored power of the shared battery 21a with a low power unit price, and the charging is terminated when the stored power of the shared battery 21a is exhausted. The Rukoto. On the other hand, if the cheap charging is not limited and added, the in-vehicle battery 41 is charged using both of the two systems of power supplied to the charge management device 22 (however, the shared battery 21a is The priority is as described above).

  In step S18, it is determined whether or not the user has entered a charge reservation after the display in step S17. When the charging reservation is input, the process proceeds to step S19. When the charging reservation is not input, it is determined whether or not the charging reservation is repeatedly input until the charging reservation is input.

  In step S <b> 19, it is determined whether or not the in-vehicle battery 41 can be charged at the date and time when the user desires to charge (charge available time determination). In the present embodiment, the number of automobiles 40 that can be charged simultaneously is limited to three or less because of the power supply capability (the amount of power that can be supplied), and at least three or more charging reservations are already made at the date and time the user desires to charge. It is determined whether or not. If the in-vehicle battery 41 cannot be charged at the desired date and time, the process proceeds to step S22, and the display device 53 displays that charging reservation is not possible. This prompts the user to input a reservation again. In step S18, it is determined whether or not the charging reservation is re-input by the user. On the other hand, if the vehicle-mounted battery 41 can be charged at the date and time the user desires to charge, the process proceeds to step S20.

  In step S20, it is determined whether or not a limited addition of bargain charging is performed. If the discount charge is limited and added, the process proceeds to step S23, and the estimated charge amount Q2 calculated in step S15 is referred to to determine whether or not the charge is possible at the date and time the user desires to charge. judge. If cheap charging is not possible, the process proceeds to step S22, and display unit 53 displays that charging reservation is not possible. This prompts the user to input a reservation again. On the other hand, if cheap charging is possible, it will progress to step S21.

  In step S21, various information of the charge reservation input by the user is stored in the storage device 51a. This process is a process for setting the charging mode. Thereby, the charge reservation data is updated. In addition, the reservation contents desired by the user (charging date and time, selection of full charge / time specified charge, limited addition of discount charge, etc.) are displayed on the display device 53. Thereby, the user can confirm the content of the charge reservation which he performed.

  In addition, even after making a charge reservation, this parking system allows reservation contents (charging date, selection of full charge / time specified charge, limited addition of discount charge, etc.) by an input operation of the operation device 52 or the terminal device 18. You can change it or cancel the reservation.

  Next, the charging control process will be described based on the flowchart shown in FIG. Note that this process is executed by the controller 51 using a charge reservation date and time stored in the storage device 51a as a trigger.

  First, in step S31, based on the detection result of the connection detection sensor 35, it is determined whether or not the charging cable 33 of the charging device 31 is connected to the automobile 40 to be charged this time. If the charging cable 33 is connected to the automobile 40 to be charged, the process proceeds to the subsequent step S32, and if not connected, the process waits as it is.

  In step S32, the remaining capacity information of the in-vehicle battery 41 is acquired. Specifically, a request signal is transmitted by the communication device 54 and information transmitted from the in-vehicle ECU 43 as a response is received. Then, the reception information is acquired as remaining capacity information.

  In step S33, it is determined whether full charge is selected as the charge mode. If full charge is selected, the process proceeds to step S34, and a full charge process is executed. On the other hand, when the full charge is not selected, the process proceeds to step S35, and the time designated charging process is executed.

  Below, each charge process of step S34, S35 is demonstrated based on the flowchart of FIG.6 and FIG.7. First, the full charge process in step S34 will be described based on the flowchart shown in FIG.

  First, in step S41, the storage amount (current storage amount) of the shared battery 21a is calculated based on the storage amount information from the storage amount detection sensor 21b. In the subsequent step S42, the current storage amount is calculated from a predetermined determination value K. It is determined whether there are too many. The determination value K is a threshold value for determining a decrease in the current power storage amount, for example, K = 0. The determination value K may be other than 0, may be a predetermined value near 0, or may be a predetermined value (provided that K> 0). Then, if the current power storage amount> K, the process proceeds to step S43, and the in-vehicle battery 41 is charged by the power stored in the shared battery 21a. At this time, the switching operation in the power switching device 56 is performed so that the stored power of the shared battery 21a is supplied to the charging device 31 corresponding to the vehicle 40 to be charged.

  If current storage amount ≦ K, the process proceeds to step S44. In step S44, it is determined whether or not a cheap charge limitation is added. In this case, if there is a limitation of discount charging, the process proceeds to step S47, where the charging device 31 is operated to stop the power supply from the charging device 31 to the in-vehicle battery 41. Thereby, charge of the vehicle-mounted battery 41 is complete | finished. Thereafter, this process is terminated.

  On the other hand, if there is no limitation of cheap charge, it will progress to step S45. In step S45, charging of the in-vehicle battery 41 with the shared power (commercial power) from the shared distribution board 14 is executed. At this time, the switching operation in the power switching device 56 is performed such that the shared power (commercial power) is supplied from the shared distribution board 14 to the charging device 31 corresponding to the automobile 40 to be charged.

  Thereafter, in step S46 following step S43 or S45, it is determined whether or not the in-vehicle battery 41 is fully charged based on the remaining capacity information of the in-vehicle battery 41 transmitted from the in-vehicle ECU 43. At this time, in addition to the determination of the full charge based on the remaining battery capacity information, it is also possible to determine a charge time required for the full charge in advance and determine that the battery has been fully charged at the timing when the charge time has elapsed.

  And if the vehicle-mounted battery 41 is fully charged, it will progress to step S47, will operate the charging device 31, and will stop the electric power supply from the charging device 31 to the vehicle-mounted battery 41. FIG. Thereby, charge of the vehicle-mounted battery 41 is complete | finished. Moreover, if the vehicle-mounted battery 41 is not fully charged, it will return to step S41 and will perform the process of step S41-S46 mentioned above again.

  Next, the time designation charging process in step S35 (see FIG. 5) will be described based on the flowchart shown in FIG. Since steps S51 to S56 in this process are the same as steps S41 to S46 (see FIG. 6) in the full charge process, description thereof is omitted here.

  If it is determined in step S56 that the in-vehicle battery 41 is not fully charged, it is determined in step S57 whether or not the specified charging time input at the time of charging reservation has elapsed. If the designated charging time has elapsed, the process proceeds to step S58, and charging of the in-vehicle battery 41 is terminated (similar to step S47 in FIG. 6). On the other hand, if the designated charging time has not elapsed, the process returns to step S51, and the processes of steps S51 to S57 are executed again.

  In addition, instead of the configuration in which the charge designation time is set at the time of charge reservation and the charging process (time-designated charge process) is performed based on the charge designation time, the charge designation amount is set at the charge reservation, The structure which implements a charging process based on may be sufficient.

  Returning to the description of FIG. 5, when each charging process in steps S <b> 34 and S <b> 35 is completed and the process proceeds to step S <b> 36, a notification of charging completion is given. Specifically, the indicator lamp 36 of the charging device 31 is turned on, or an announcement by a sound device (not shown) is performed. Alternatively, a charging completion notification is transmitted to the terminal device 18 of each user. Thereby, the user can know that the charging of the in-vehicle battery 41 is completed.

  In the following step S37, the amount of power supplied by the current charging is calculated. At this time, for example, the amount of supplied power is calculated based on a measurement result of a power meter (not shown) provided in the charging device 31.

  Finally, in step S38, a charging fee (power supply fee) is calculated based on the amount of power supplied this time and the unit price of power used, and information on the charging fee is sent to the management computer 62 of the management company via the Internet 61. Send. Thereafter, this process is terminated. As a result, the management computer 62 can confirm the charging fee of each resident, and can charge the resident together with the rent, the parking fee, etc. together with the charging fee.

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

  When the user makes a charge reservation, the charge management device 22 obtains a user charge request (parking position number, password, desired charging date and time, charging time, etc.) for each parking space 29 and the power storage device 21 (shared battery). 21a) side charging conditions (estimated storage amount Q2, charging price) are set. Moreover, the embodiment of charging is set (charging reservation data is updated) based on the user charging request and the charging condition. According to this configuration, the embodiment of charging is set based on the convenience of both the user side and the power storage device 21 side. Therefore, when the charging request is issued, the user is required for the charging time. It becomes possible to grasp. Thereby, it can suppress that the charge to the vehicle-mounted battery 41 is prolonged rather than an initial plan. Moreover, it can suppress that the charge to the vehicle-mounted battery 41 stops on the way unexpectedly. As a result, when charging the in-vehicle battery 41 with a plurality of automobiles 40 as charging targets, it is possible to suitably charge the in-vehicle battery 41 while meeting each user's request.

  Since a plurality of charging requests are stored in the storage device 51a as time-series charging reservation data and the presence / absence of the charging free time is determined based on the charging reservation data, the charging free time is effectively used and the in-vehicle battery 41 is charged. It can be done efficiently. In addition, since the charging execution time can be easily grasped, the convenience for the user is improved.

  When charging reservation is made, the full charge / time-designated charge mode selection and the charge designation time are input, so that the in-vehicle battery 41 can be charged according to the charge amount or charge time desired by the user. . Further, by storing these pieces of charge amount information in the storage device 51a as charge reservation data, it becomes possible to appropriately set the charging mode in the subsequent charge reservation for other users.

  In the case of charging reservation, since the charging reservation information and the charging price are displayed on the display device 53 before inputting the reservation, the user can determine the reservation contents while checking the reservation status and the charging price each time. it can.

  A plurality of electric power having different power unit prices can be supplied, and the charging management device 22 is configured to supply the charging device 31 with power having a lower power unit price preferentially when charging the in-vehicle battery 41, thereby reducing the economic burden on the user. can do.

  When charging reservation is made, a limited additional input for cheap charging is performed. Therefore, whether or not only relatively inexpensive power is used, in other words, which of a plurality of powers with different power unit prices is used, is determined by the user. You can select according to your intention.

  The automobile 40 is charged using the electric power of the shared part supplied from the shared distribution board 14. Here, it is possible to charge the automobile 40 using the electric power supplied from the dedicated circuit by separately wiring the dedicated circuit and the charging device 31 of each household. If configured, the amount of wiring becomes enormous and the cost may increase significantly. In this regard, according to the configuration of the present embodiment, the wiring can be simplified. That is, it can be expected to reduce the work load and the wiring cost at the time of installation and construction of the parking system.

  The night battery and the power generated by the solar panel 25 are stored in the shared battery 21 a of the power storage device 21, and the stored power is used for charging the in-vehicle battery 41. Thereby, even if it is not a night time slot | zone, utilization of the comparatively cheap night electric power is attained. In addition, the combined use of the power generated by the solar panel 25 can further reduce the cost. Therefore, the economical burden on the user can be reduced.

  Since the charging device 31 is installed in each parking space 29, charging can be performed while the automobile 40 is parked in the parking space 29. That is, since it is not necessary to move the automobile 40 to another place (charging place) in order to charge the automobile 40, it is convenient for residents. Moreover, since it is not necessary to separately install a parking space dedicated to charging, the site area of the apartment house 10 is not reduced.

  When the vehicle in any parking space 29 is charged by the charge management device 22, information related to the charge amount or the charge fee is transmitted to the management computer 62 of the management company. In this case, since the management company that manages the house can check the information on the charge amount or the charge fee by the management computer 62, the user may charge the user with the charge fee together with the rent or the parking fee. it can.

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

  In the above embodiment, priority is given to the battery stored power from the power storage device 21 among the two systems of power supplied to the charge management device 22 (shared power from the shared distribution board 14 and battery stored power from the power storage device 21). However, this may be changed. For example, when charging the in-vehicle battery 41, it is determined whether or not the current time is a night time zone. If the current time is a night time zone, the shared distribution board 14 is not the battery stored power from the power storage device 21 but the battery distribution power. The in-vehicle battery 41 is charged with the shared power from the vehicle. In this case, in the night time zone, the shared power supplied from the shared distribution board 14 becomes night power (relatively cheap power), so that the vehicle-mounted battery 41 can be charged using the night power. .

  The electric capacity of the in-vehicle battery varies depending on the type of automobile to be charged. Therefore, it is preferable to input the vehicle type information by the operation device 52 at the time of charging reservation, and to create the charging reservation data in consideration of the vehicle type information.

  In the above embodiment, the charge reservation is made by operating the operation device 52 or the terminal device 18 of the charge management device 22 at the time of charge reservation, but this is changed to an electronic key (so-called smart key) or a mobile phone. It is good also as a structure which performs charge reservation using the portable communication device which consists of these. For example, the user's parking position number and password are stored in advance in the memory of the portable communication device. And at the time of a charge reservation, each information may be transmitted to the controller 51 from a portable communication device by bringing a portable communication device close to the charge management apparatus 22, and the controller 51 may acquire the transmitted information. In this configuration, since the user's input operation at the time of charging reservation can be simplified, the convenience for the user can be improved.

  As a user or automobile authentication method, another authentication means may be used instead of the password. For example, a method of performing authentication based on the user's biometric information such as a fingerprint, a retina, an iris pattern, a blood vessel vein pattern, and a voice (voice print) can be considered. It is also possible to provide an authentication information transmitter in the vehicle and perform authentication based on the authentication information from the transmitter.

  Moreover, you may make it transmit the notification of charge completion with respect to a portable communication device at the time of charge completion. Thereby, even when the user is out, it can be known that the charging of the automobile 40 is completed.

  In the said embodiment, although it was set as the structure which stores the electric power by the solar power generation of the solar panel 25 in the shared battery 21a of the electrical storage apparatus 21, it is good also as a structure which does not perform the electrical storage by a solar power generation by changing this structure.

  In the above embodiment, the power storage device 21 (shared battery 21 a) stores nighttime power or solar power generation power and uses the stored power to charge the in-vehicle battery 41. However, the power storage device 21 is not provided. There may be. For example, the vehicle-mounted battery is configured to be charged with commercial power (shared power) supplied from the shared distribution board 14. In this case, it is possible to charge the in-vehicle battery with inexpensive power on condition that the charging time zone is nighttime (a time zone in which power is cheap).

  In the above embodiment, the controller 51 of the charge management device 22 and the management computer 62 of the management company are connected via the Internet 61, but this may be changed. For example, the controller 51 and a credit card company management computer may be connected via the Internet 61. In this configuration, the charging fee can be charged from the credit card company by transmitting the charging fee information to the credit card company.

  In the said embodiment, although the parking system of this invention was applied with respect to the parking lot 28 in the apartment house 10, the parking system of this invention is applied with respect to paid parking lots, such as a monthly parking lot and a time rental parking lot. Also good. In this case, it is advisable to collect the charging fee together with the parking fee when the car is released from the parking lot.

  The vehicle to be charged may be other than a passenger car, and may be a transport truck, an industrial vehicle, or a two-wheeled vehicle.

  In the above embodiment, the charging reservation is made by operating the operation device 52 of the charge management device 22, but this may be changed. For example, an in-vehicle terminal may be provided in the automobile 40 so that a charging operation can be performed from the in-vehicle terminal. That is, an in-vehicle terminal is used instead of the operation device 52. In this case, the user operation information is transmitted from the in-vehicle terminal to the charge management device 22 by wireless communication or wired communication. Thereby, the user can perform the charging operation while being in the automobile 40.

  Moreover, it is good also as a structure which connects the controller 51 of the charge management apparatus 22 with a card dealer via the internet. In this case, an oil detector, a failure detector, or the like may be provided in the automobile 40 so that a detection signal is transmitted from these detectors to the car dealer. Then, since the card dealer can acquire failure information, oil amount information, etc. of the user's automobile 40, it becomes possible to perform appropriate maintenance on the user's automobile 40 at an appropriate time.
