Next, among the charging preferable temperature charging devices, the second charging priority is assigned to the charging device for the electric vehicle in which the charging coupler 222 is inserted / extracted second time. On the other hand, the charging priority of the charging device for electric vehicles whose average internal temperature is higher than the temperature threshold is the lowest.

In step S305, the first management apparatus 10 stores the determined charging priority order in the storage unit 12.

  Next, in step S207, the first management device 10 induces charging the electric vehicle charging device having the highest charging priority among the electric vehicle charging devices 20a to 20f based on the determined charging priority. Determine as a device.

Next, in step S208, the first management device 10 transmits an induction display signal to the electric vehicle charging device determined as the induced charging device. Next, in step S209, the electric vehicle charging device to which the guidance display signal is transmitted receives the guidance display signal.

  Then, in step S210, the electric vehicle charging device determined as the inductive charging device lights up the state display unit 213 in blue light and displays an induction display.

  As described above, in the flow shown in FIG. 5, the charging device for an electric vehicle having the smallest number of insertion / extraction of the charging coupler 222 is used as the induced charging device, thereby Prompt to use. Thereby, the charging coupler insertion / extraction frequency of each electric vehicle charging device can be leveled. In addition, since the lowest charging priority is assigned to the charging device for electric vehicles whose average internal temperature is higher than the temperature threshold value, the charging device for electric vehicles having a high average internal temperature may be used for charging. Can be lowered.

  In step S206, the charging priority is determined based on the flow shown in FIG. 6, but the charging priority can be determined using other methods.

  FIG. 7 is a diagram showing another charging priority order determination processing flow. The flow shown in FIG. 7 is executed by the control unit 11 of the first management apparatus 10 by a computer program stored in the storage unit 12 of the first management apparatus 10.

  First, in step S401, the first management apparatus 10 determines that the average internal temperature of the electric vehicle charging device exceeds the temperature threshold value stored in the storage unit 12, based on the average internal temperature information included in the temperature information. It is determined whether or not.

  When the average internal temperature of the electric vehicle charging device is lower than the temperature threshold, the process proceeds to step S402. On the other hand, when the average internal temperature of the electric vehicle charging device is higher than the temperature threshold value, the process proceeds to step S403.

  If the average internal temperature of the electric vehicle charging device is lower than the temperature threshold value, in step S402, the first management device 10 stores the electric vehicle charging device in the storage unit 12 as a preferred charging temperature charging device. Remember.

  On the other hand, if the average internal temperature of the electric vehicle charging device is higher than the temperature threshold value, in step S403, the first management device 10 stores the electric vehicle charging device as a non-chargeable preferred temperature charging device. Store in unit 12.

  Next, in step S404, it is determined whether or not the process of step S401 has been executed for all of the electric vehicle charging devices 20a to 20f. If it is determined that the process of step S401 is performed for all of the electric vehicle charging devices 20a to 20f, the process proceeds to step S405. On the other hand, when it determines with the process of step S401 not being performed about all the charging devices 20a-20f for electric vehicles, a process returns to step S401.

  Next, in step S405, the first management device 10 calculates the number of insertions / removals stored in the storage unit 12 based on the number of times of insertion / removal of the charging coupler included in the charging coupler insertion / removal information. Determine whether the threshold is exceeded. Here, the insertion / extraction threshold value used is set as a variable based on the life of the electric vehicle charging device and the maximum insertion / extraction number of the charging coupler 222. For example, when the lifetime of the electric vehicle charging device is 5 years and the maximum number of insertions / removals of the charging coupler 222 is 10,000, the threshold for the number of insertions / removals after 1 year has been set to 2,000 times after installation, The insertion / removal frequency threshold after 2 years from the installation can be set to 4,000 times, and the insertion / removal threshold after 5 years from the installation can be set to 10,000.

  If the charging coupler insertion / extraction number of the electric vehicle charging device is smaller than the insertion / extraction number threshold, the process proceeds to step S406. On the other hand, when the charging coupler insertion / extraction number of the electric vehicle charging device is larger than the insertion / extraction number threshold, the process proceeds to step S407.

  If the charging coupler insertion / extraction count of the electric vehicle charging device is smaller than the insertion / extraction threshold, the first management device 10 stores the electric vehicle charging device as a suitable charging insertion / extraction charging device in step S406. 12 to store.

  If the charging coupler insertion / extraction frequency of the electric vehicle charging device is higher than the insertion / extraction frequency threshold value, in step S407, the first management device 10 stores the electric vehicle charging device as a non-charging suitable insertion / extraction charging device. Store in unit 12.

  Next, in step S408, it is determined whether or not the process of step S405 has been executed for all of the electric vehicle charging devices 20a to 20f. When it is determined that the process of step S405 is performed for all of the electric vehicle charging devices 20a to 20f, the process proceeds to step S409. On the other hand, when it determines with the process of step S405 not being performed about all the electric vehicle charging devices 20a-20f, a process returns to step S405.

  Next, in step S409, the first management apparatus 10 determines the charging priority based on the determination results of steps S401 and S405. As a result of the determinations in steps S401 and S405, the electric vehicle charging devices 20a to 20f are divided into four groups as shown in FIG.

FIG. 8 is a diagram showing the classification of the charging device for the electric vehicle in the charging priority order determination processing flow shown in FIG. Referring to FIG. 8, the electric vehicle charging devices are classified into four groups based on a temperature threshold value T _T and an insertion / extraction frequency threshold value T _N. The first priority charging device group G ₁ is a charging temperature suitable charging device determined to be and the charging device for an electric vehicle determined to charge preferred insertion charging device in step S405 in step S401. Second priority charging device group G ₂ is a charging temperature suitable charging device determined to be and non-charging preferred insertion charging device and the determined electric vehicle charging system in step S405 in step S401. The third priority charging device group G ₃ is a charging device for an electric vehicle that is determined as a non-charging suitable temperature charging device in step S401 and determined as a charging suitable insertion / extraction charging device in step S405. The fourth priority charging device group G ₄ is a non-charging temperature suitable charging device determined to be and non-charging preferred insertion charging device and the determined electric vehicle charging system in step S405 in step S401.

In step S409, the first control apparatus 10, when determining the charging priority, charging all electric vehicles included in each group of first prioritized charge unit group G ₁ ~ fourth priority charging device group G ₄ The devices are determined as the same order. That is, the charging priority for an electric vehicle charging system included in the first priority charging device group G ₁ is determined as position 1, the charging priority for an electric vehicle charging device included in the second priority charging device group G ₂ Decide as 2nd place. Further, the charging priority of the third priority Charging priority for an electric vehicle charging device included in the device group G ₃ determines as a 3-position, the electric vehicle battery charger included in the fourth priority charging device group G ₄ Determined as 4th place.

In step S410, the first management device 10 stores the determined charging priority order in the storage unit 12.

  In the charging priority order determination processing flow shown in FIG. 7, the charging priority order is assigned to each group classified based on the temperature threshold value and the insertion / extraction number threshold value. It can be determined as the same rank. For this reason, the charging priority of a plurality of electric vehicle charging devices satisfying the determination requirement based on the temperature threshold value and the insertion / extraction frequency threshold value can be determined as the first. Thereby, it is possible to provide the user with an induction display having a higher selectivity than the charging priority order determination method shown in FIG. For example, when the electric vehicle charging devices 20a to 20f are initially installed, all the electric vehicle charging devices satisfy the determination requirements based on the temperature threshold value and the insertion / extraction frequency threshold value, so the charging priority ranks first. It is determined. For this reason, since the 1st management apparatus 10 can determine all the charging devices for electric vehicles as a to-be-guided device, it becomes possible for all the charging devices for electric vehicles to display an induction | guidance | derivation display.

  Further, in the charging priority order determination processing flow shown in FIG. 7, the insertion / removal frequency threshold is set as a variable based on the life of the electric vehicle charging device and the maximum insertion / removal number of the charging coupler 222. The number of times can be managed more accurately. That is, in order to determine the electric vehicle charging device suitable for charging by associating the lifetime of the electric vehicle charging device with the maximum number of insertions / removals of the charging coupler 222, the remaining life of the entire electric vehicle charging device and the charging coupler 222 are determined. It is possible to reduce the difference from the remaining life of the battery.

  FIG. 9 is a diagram showing another charging priority order determination processing flow. The flow shown in FIG. 9 is executed by the control unit 11 of the first management apparatus 10 by a computer program stored in the storage unit 12 of the first management apparatus 10.

  First, in step S501, the first management apparatus 10 determines priorities according to the charging priority order determination processing flow shown in FIG.

Then, in step S502, the first control apparatus 10 determines whether the number of electric vehicle charging system included in the first priority charging unit group G ₁ is greater than the number of the desired object inductive charging device. If the number of the electric vehicle battery charger included in the first priority charging unit group G ₁ is greater than the number of the desired object inductive charging device, the process is terminated. On the other hand, when the number of electric vehicle charging system included in the first priority charging unit group G ₁ is less than the number of the desired object inductive charging device, the process proceeds to step S503.

Next, in step S503, the first management apparatus 10 changes the temperature threshold value T _T from the temperature threshold value T _T ′, which is higher by a predetermined temperature, and the number of insertions / removals, which is greater by a predetermined number of times from the insertion / removal time threshold value T _N. Change to threshold T _N ′. Next, the process returns to step S501 to determine the priority order again.

FIG. 10 is a diagram illustrating classification of the charging device for the electric vehicle by the changed temperature threshold value T _T ′ and insertion / extraction frequency threshold value T _N ′. As shown in FIG. 10, the charging priority determining processing flow shown in FIG. 9, by changing the temperature thresholds and the insertion count threshold, electric vehicles included in the first priority charging device group G ₁ It is possible to add the number of charging devices.

In the charging priority order determination processing flow shown in FIG. 9, when the number of electric vehicle charging devices included in the first priority charging device group G ₁ is smaller than the desired number of induced charging devices, the temperature threshold value T _T. Further, the charging priority order is determined again by changing the insertion / extraction number threshold value _TN . For this reason, it is possible to add a suitable electric vehicle charging device 20a to the induced charging device in consideration of both the average internal temperature of the electric vehicle charging device 20a and the number of insertions / removals of the charging coupler 222.

  The configuration and function of the first electric vehicle charging device management system 1 have been described above with reference to FIGS. 1 to 10, but other embodiments will be described below.

  In the first electric vehicle charging device management system 1, it is determined in step S201 whether or not the vehicle is close, but the first management device 10 determines whether or not the vehicle is close. The process can be executed without In this case, the first management device 10 transmits the charging coupler insertion / removal information request signal and the temperature information request signal to the electric vehicle charging devices 20a to 20f at a constant cycle. Further, the vehicle detector 16 of the first management device 10 includes a moving body detection unit including an infrared sensor and an image capturing unit including a CCD sensor, and includes either the moving body detection unit or the image capturing unit. It may be. Similarly, each of the charging vehicle detectors 238 of the electric vehicle charging devices 20a to 20f includes a moving body detection unit including an infrared sensor and an image capturing unit including a CCD sensor. You may make it the structure which has either one.

  Moreover, although the 1st electric vehicle charging device management system 1 contains the six electric vehicle charging devices 20a-20f, the electric vehicle charging device should just be two or more. When the electric vehicle charging device management system includes 32 electric vehicle charging devices, the number of electric vehicle charging devices that display the inductive display is preferably 10% to 20%. For example, the number of electric vehicle charging devices that display an inductive display can be five. This is because if there are few electric vehicle charging devices that display the guidance display, a plurality of electric vehicles may face the single electric vehicle charging device, which may cause confusion.

  In addition, the first management device 10 includes charging units such as a charging cable 220, a charging coupler 222, and a switch 240, a status display unit 213, a charging display unit 214, and a charging coupler detector 236. You may have the component apparatus which has. Thereby, the 1st management apparatus 10 can charge an electric vehicle similarly to the charging devices 20a-20f for electric vehicles. In this case, since the 1st management apparatus 10 can be arrange | positioned instead of either of the charging devices 20a-20f for electric vehicles, the site of the parking lot 30 can be used effectively.

  The first management apparatus 10 determines the charging priority using the charging coupler insertion / extraction information and the temperature information as the life related information, but determines the charging priority using other life related information. Also good. For example, the charging priority order may be determined based on other internal device life information in addition to the charging coupler insertion / extraction information or instead of the charging coupler insertion / extraction information. The internal device life information includes switch operation information corresponding to the number of operations of the switch 240, illumination lighting time information, status display unit lighting time information, display unit lighting time information, speaker operating time information, and fan rotation time information. included.

  When determining the charging priority order based on the switch operation information, the charging priority order of the charging device for the electric vehicle with the smallest number of operations of the switch 240 is determined to be first. In addition, when the charging priority is determined based on the lighting lighting time information, the status display portion lighting time information, the display portion lighting time information, the speaker operating time information, and the fan rotation time, the charging for the electric vehicle having the shortest cumulative operating time respectively. The charging priority of the device is determined to be first.

  Further, although the average internal temperature is used as the temperature information, the internal temperature detected by the internal temperature detector 239 may be used instead of the average internal temperature. Moreover, you may use only any one of internal apparatus lifetime information or temperature information as lifetime relevant information used when determining an induced charging apparatus.

  Further, in step S207, the charging device for the electric vehicle having the highest charging priority is determined as the induced charging device, but the first management device 10 adds the plurality of electric vehicle charging devices in descending order of the charging priority. You may determine as an induced charging device.

  Further, in step S210, the charging device for an electric vehicle determined as the inductive charging device lights up the status display unit 213 in blue light to display the guidance display, but the guidance display displayed on the status display unit 213 is Other colors may be displayed. For example, the guidance display displayed on the status display unit 213 may emit light from orange to a warm color centered on red when the temperature is low, and may emit a cool color centered on blue when the temperature is high. Here, the air temperature is estimated by the internal temperature detected by the internal temperature detector 239 and a look-up table indicating the relationship between the internal temperature and the air temperature stored in the charging storage unit 232.

Moreover, in step S604, the vehicle determination device 50 adds information indicating that the vehicle is a non-charged vehicle to the vehicle information, but may add information indicating that the vehicle is not an electric vehicle to the vehicle information. In this case, in step S612, the second management device 40 determines whether or not the vehicle is an electric vehicle based on the vehicle information received from the vehicle determination device 50. When it is determined that the vehicle is an electric vehicle, in step S613, the second management device 40 determines the electric vehicle charging device having the highest charging priority as the induced charging device. When it determines with a vehicle not being an electric vehicle, the 2nd management apparatus 40 determines the charging device for electric vehicles with the lowest charge priority as an induced charging device in step S614.

  In step S613, the charging device for the electric vehicle having the highest charging priority is determined as the induced charging device, but the second management device 40 selects the plurality of electric vehicle charging devices in descending order of the charging priority. It can be determined as an induced charging device.

  In step S614, the charging device for the electric vehicle having the lowest charging priority is determined as the induced charging device, but the second management device 40 selects the plurality of charging devices for the electric vehicle in ascending order of the charging priority. It can be determined as an induced charging device.

  In step S708, the second management device 40 determines the reserved charging device as the charging device for the electric vehicle having the lowest average internal temperature, but the charging device for the electric vehicle with the smallest number of insertion / removal of the charging coupler 222 is selected. You may decide as a reservation charging device.

  In step S709, the reservation information signal is transmitted only to the portable information terminal device 90, but the reservation information signal may be transmitted to the vehicle determination device 50. When the reservation information signal is received, the vehicle determination device 50 displays the position of the reserved parking space, the color of the reservation display, and the like on the determination display unit 55, and a user other than the reservation person parks the parking corresponding to the reserved parking position. Alerts can be made not to park the vehicle in space.

  Further, the processing shown in the flow of FIG. 5 can be performed not only in the first electric vehicle charging device management system 1 but also in the second electric vehicle charging device management system 2.

  In the second electric vehicle charging device management system 2, various services may be provided based on the charging priority determined by the second management device 40. For example, when using an electric vehicle charging device having a long remaining life, that is, a high charging priority, the system may be cheaper than using other electric vehicle charging devices. Moreover, when using the charging device for electric vehicles with a high charge priority, it is good also as a system which gives more points than the case where the charging device for other electric vehicles is used. In such a case, by setting the state display unit 213 of the electric vehicle charging device having a high charging priority to a specific display form, the usage fee of the electric vehicle charging device is low, or many points are given. To the user. By adopting such a configuration, it is possible to guide the user to the charging device for an electric vehicle having a high charge priority by notifying the user in advance that an incentive such as a point is given.
