The "predetermined state of the removable battery 100" can be determined based on the SOC, SOH, temperature, etc. of the removable battery 100, for example.

Here, the determination method of the “predetermined state of the removable battery 100 ” may be determined by, for example, a business operator that provides a replacement service for the removable battery 100 in the charging/discharging station device 200 . In this case, the business operator that provides the exchange service may, for example, for operational reasons, decide to recommend the removable battery 10 in a state in which the user actively wants to use it. be able to control.

For example, when the "predetermined state of the removable batteries 100" is determined based on the SOC, the removable batteries 100 can be ranked according to the length of time elapsed since the completion of charging obtained from the SOC. In this case, for example, each detachable battery 100 is determined with a tendency to determine that the detachable battery 100 is in a predetermined state as the elapsed time from the completion of charging increases. can be preferentially lent out. As a result, as with general storage batteries, business operators can reduce the deterioration of the detachable battery 100 as much as possible as the elapsed time from the completion of charging (longer the time in a fully charged state) is longer. A replacement service for the removable battery 100 can be provided with reduced operations. In other words, it is possible to provide a replacement service for the removable battery 100 in such an operation that the removable battery 100 is used as much as possible after charging is completed.

Further, for example, when the "predetermined state of the removable battery 100" is determined based on the SOH, the respective removable batteries 100 can be ranked according to the progress of deterioration obtained from the SOH. In this case, for example, each detachable battery 100 is determined with a tendency to determine that the detachable battery 100 is in a predetermined state as the progress of deterioration decreases, and the detachable battery 100 that is closer to new is preferentially rented out. can be As a result, the business operator can provide a replacement service for the removable batteries 100 in such an operation that the progression of deterioration of the respective removable batteries 100 becomes uniform. As a result, the operator can reduce the frequency of maintenance to replace the deteriorated and unusable detachable batteries 100 with new ones, and replace all the detachable batteries 100 with new ones at the same time. For example, maintenance work can be facilitated. Conversely, for example, each detachable battery 100 is determined with a tendency to determine that the detachable battery 100 is in a predetermined state as the deterioration progresses, and the detachable battery 100 is degraded (however, the detachable battery 100 is unusable). The detachable battery 100, whose deterioration has not progressed to a certain level, can be lent preferentially. As a result, the operator can prevent the detachable batteries 100 from deteriorating unevenly, that is, from deteriorating the detachable batteries 100 at the same time to an unusable level. A replacement service for the removable battery 100 can be provided by avoiding this operation. As a result, the operator averages the maintenance frequency of replacing the degraded and unusable detachable battery 100 with a new detachable battery 100 and replaces the detachable battery 100 with a new detachable battery in one maintenance operation. By reducing the number of 100, the cost required for maintenance work can be suppressed. Note that when the “predetermined state of the detachable battery 100” is determined based on the SOH, the degree of progress of deterioration of each detachable battery 100 is compared in an area within the image generated by the image generation unit 340. All the removable batteries 100 existing in all the charging/discharging station devices 200 may be targeted, or the removable batteries 100 existing in the same charging/discharging station device 200 may be targeted.

Further, for example, when the “predetermined state of the removable battery 100 ” is determined based on temperature, each removable battery 100 can be ranked according to the temperature of the removable battery 100 . In general storage batteries, when the temperature reaches a low temperature range (for example, 15° C. or lower), the reaction in the storage battery tends to deteriorate and the output capacity tends to decrease. Conversely, when the temperature of the storage battery approaches the upper limit temperature (for example, about 60° C. in the case of a ternary lithium battery), the efficiency of power supply tends to be affected. Therefore, when the "predetermined state of the removable battery 100" is determined based on the temperature, for example, if the detachable battery 100 is in the predetermined state when the temperature is within a predetermined range (for example, 20° C. or higher and 40° C. or lower). It is possible to determine each removable battery 100 based on the tendency to determine that there is a temperature, and preferentially lend the removable battery 100 whose temperature is within a predetermined range. This allows the operator to reduce the output capacity due to low temperatures, reduce the efficiency of power supply due to high temperatures, or detachable batteries that may be less efficient, similar to general storage batteries. A replacement service for the removable battery 100 can be provided in such an operation that the battery 100 is less likely to be lent out. "The efficiency of power supply decreases due to high temperature" means, for example, a decrease in supplied power due to a safety function that suppresses temperature rise of the removable battery 100 by decreasing the power supplied when the temperature rises. Also includes When the "predetermined state of the detachable battery 100" is determined based on the temperature, the determination of the temperature of each detachable battery 100 may be performed based on the current temperature. 200, that is, based on the temperature when the removable battery 100 is actually rented.

It should be noted that the determination of the “predetermined state of the removable battery 100” is made when, for example, the usage status of the removable battery 100 by the user who requested replacement of the removable battery 100 is recorded in the user information management table 362. You may consider the usage situation. For example, the user who requested replacement of the removable battery 100 replaces the removable battery 100 early. ), it is possible to rent a detachable battery 100 with an SOC equal to or higher than a predetermined value, even if the detachable battery 100 is not fully charged. In this case, the standard of the SOC value in determining the "predetermined state of the removable battery 100" based on the SOC is set to a predetermined value (for example, the SOC is 100%) lower than the fully charged value (for example, the SOC is 100%). 80%), and the detachable battery 100 exceeding this predetermined value may be subject to determination. Then, for example, the detachable batteries 100 may be ranked such that the detachable battery 100 with an SOC value of 80% is ranked highest. Further, for example, if the user who requested replacement of the removable battery 100 is a user who tends to replace the removable battery 100 after using it until the charge is almost completely discharged, the position of the user (more specifically, Practically, the detachable battery 100 located closer to the position of the terminal device 400 may be rented. In this case, the SOC in the determination of the "predetermined state of the removable battery 100" based on the SOC is a fully charged value (for example, the SOC value is 100%), and the removable battery 100 closest to the user's current position is the closest. Each removable battery 100 may be ranked so as to be ranked higher. The usage status of the removable battery 100 by the user can be determined by, for example, machine learning, deep learning, AI (Artificial Intelligence), or the like. You may use it as data for learning etc.

It should be noted that the process of determining the "predetermined state of the removable battery 100", the process of ranking the removable batteries 100, and the process of selecting the charging/discharging station device 200 in which the removable battery 100 with the highest rank exists are performed by image generation. A component other than the unit 340 may perform this, and the image generation unit 340 may be configured to only generate an image that enables the user to recognize the position where the selected charge/discharge station device 200 is installed.

[First example of image]
FIG. 9 is a diagram showing an example of an image provided by the management server 300. As shown in FIG. The image IM1 shown in FIG. 9 is an image in which a triangular mark LT is superimposed as an icon representing the position of the terminal device 400 and a pin mark LB is superimposed as an icon representing the position of each charging/discharging station device 200 in the local map. is an example. In the image IM1, the ranking of the removable batteries 100 ranked according to a predetermined condition is indicated by pin marks LB with numbers representing the ranking. For example, the image IM1 shows the positions of the charging/discharging station devices 200 where the removable batteries 100 ranked up to the fourth rank are present. By transmitting this image IM1 to the terminal device 400 and displaying it on the display unit 420, the management server 300 can perform charging/discharging operations in which the detachable battery 100 having a small number (high ranking) indicated in the pin mark LB is present. Station device 200 can be presented to the user as charging/discharging station device 200 that recommends replacement of removable battery 100 . It should be noted that the number indicated by the pin mark LB is not limited to the rank itself of the removable battery 100 . For example, if the electric vehicle 10 can be equipped with two removable batteries 100, the required number of charged removable batteries 100 in the electric vehicle 10 is two. In this case, based on the ranking of the top two removable batteries 100 present in each charging/discharging station device 200, the ranking ranking of the charging/discharging station devices 200 may be indicated by the number indicated by the pin mark LB. For example, the rank of each removable battery 100 may be scored, and the charging/discharging station devices 200 may be ranked in descending order of the total points of the top two removable batteries 100 . In other words, the degree of recommendation may be judged comprehensively, and the order may be indicated by the number indicated by the pin mark LB.

Note that, for example, when a plurality of charge/discharge station devices 200 with a high degree of recommendation are installed nearby, pin marks LB representing the positions of the respective charge/discharge station devices 200 overlap in the image generated by the image generation unit 340. It will be. In this case, the image generation unit 340 displays the pin mark LB of the charging/discharging station device 200 with a higher recommendation degree closer to the front, and displays the pin mark LB of the charging/discharging station device 200 with a lower recommendation degree further back (in other words, For example, an image is generated that is displayed so as to be hidden behind the pin mark LB in front). In image IM1, of the two charging/discharging station devices 200 in region R1, the charging/discharging station device 200 indicated by the pin mark LB, which ranks first in the degree of recommendation, is displayed in the foreground, and the ranking in the degree of recommendation is fourth. shows a state in which the charging/discharging station device 200 indicated by the pin mark LB is hidden.

[Ranking process]
Here, the ranking processing of the removable batteries 100 performed when the image generation unit 340 generates an image will be described. The ranking of the removable batteries 100 in the image generator 340 is performed based on the required number of charged batteries in the electric vehicle 10 and the predetermined state of the removable batteries 100 based on, for example, SOC, SOH, temperature, and the like. . In the following description, for ease of explanation, the required number of charged batteries in the electric vehicle 10 is one, and the "predetermined state of the removable battery 100" is determined based on the SOH. , to rank each removable battery 100 . The ranking of the removable battery 100 represents the degree of recommendation of the charging/discharging station device 200 to the user.

FIG. 10 is a flow chart showing an example of the process flow of ranking the removable batteries 100 in the image generator 340 . The process of this flowchart is executed each time the site providing unit 330 receives a request from the terminal device 400 and the image generating unit 340 generates the image IM.

When the site providing unit 330 outputs information indicating that the request from the terminal device 400 has been received, the image generating unit 340 acquires a local map centered on the position of the terminal device 400 from the map information 366 ( step S100).

Subsequently, the image generation unit 340 converts the battery information (here, SOH information) of the removable batteries 100 in each of the charging/discharging station devices 200 installed within the range of the acquired local map to the charging/discharging station device. Acquired from the state table 364 (step S110).

Subsequently, the image generation unit 340 confirms whether or not the provision of the removable battery 100 with a high SOH is prioritized as the degree of recommendation for recommending the charging/discharging station device 200 to the user (step S120). In other words, the detachable battery 100 whose deterioration has progressed (however, the deterioration has not progressed to an unusable level) is preferentially rented out, or the progress of deterioration is small (more new). close) confirms whether the removable battery 100 should be preferentially rented out. It should be noted that whether the detachable battery 100 that has deteriorated is preferentially rented or the detachable battery 100 that is less degraded is preferentially rented depends on the exchange service of the detachable battery 100. is determined in advance by a company that provides the image, and is set in the management server 300 or the image generation unit 340 .

If it is confirmed in step S120 that priority is given to providing the removable battery 100 with a high SOH (deterioration is not progressing), the image generation unit 340 selects each of the acquired removable batteries in descending order of the SOH value. 100 are ranked (step S132).

On the other hand, in step S120, priority is not given to providing the removable battery 100 with a high SOH (deterioration is not advanced), that is, priority is given to provision of the removable battery 100 with a low SOH (deterioration is progressing). is confirmed, the image generator 340 ranks the obtained removable batteries 100 in descending order of SOH value (step S134).

Subsequently, the image generation unit 340 determines whether or not the ranking of all the acquired removable batteries 100 has been completed (step S140). If it is determined in step S140 that the ranking of all the acquired removable batteries 100 has not been completed, the image generator 340 advances the process to step S120. Then, the image generator 340 repeats the ranking process (the process of steps S120 to S140) for each of the acquired removable batteries 100. FIG.

On the other hand, if it is determined in step S140 that the ranking of all of the acquired removable batteries 100 has been completed, the image generator 340 selects the ranked removable battery 100 based on the ranking of each of the removable batteries 100 with the highest ranking. The charging/discharging station device 200 with the type battery 100 is selected (step S150).

Next, image generation unit 340 places pin marks LB showing numbers indicating the ranking (degree of recommendation) of the selected charge/discharge station device 200 in the acquired local map to each corresponding charge/discharge station device 200. generates an image superimposed on the position of (step S160). In addition to superimposing the pin mark LB of each charging/discharging station device 200, the image generation unit 340 superimposes the triangular mark LT on the position of the terminal device 400 in the local map. Then, the image generator 340 ends the processing of this flowchart.

In this manner, image generator 340 generates image IM1 as shown in FIG. 9 and outputs generated IM1 to site provider 330 . The site providing unit 330 then transmits the image output by the image generating unit 340 to the terminal device 400 using the server communication unit 310 . As a result, the image generated by the image generation unit 340 is displayed on the display unit 420 of the terminal device 400, and information on the degree of recommendation of each charging/discharging station device 200 is presented to the user. Then, the user can select the charging/discharging station device 200 to replace the removable battery 100 based on the presented information on the degree of recommendation of each charging/discharging station device 200, and go to the selected charging/discharging station device 200. can.

Note that when the user selects any pin mark LB in the image displayed on the display unit 420 of the terminal device 400, the image generation unit 340 is installed at the position of the selected pin mark LB. An image that presents the order of the removable batteries 100 present in the charging/discharging station device 200 and battery information (for example, SOC information) by, for example, a pop-up screen may be generated. In this case, the user can check the state of the removable battery 100 in each recommended charging/discharging station device 200 and go to the selected charging/discharging station device 200 .

In the flowchart of the ranking process shown in FIG. 10, each removable battery 100 is ranked by determining the "predetermined state of the removable battery 100" based on the SOH. However, as described above, the "predetermined state of the removable battery 100" may be determined based on the SOC and temperature of the removable battery 100, and the removable batteries 100 may be ranked. Further, as described above, the "predetermined state of the removable battery 100" may be determined in consideration of the usage status of the removable battery 100 by the user, and the removable batteries 100 may be ranked. In this case, the "predetermined state of the removable battery 100" is determined in consideration of the SOC and temperature of the removable battery 100 and the user's usage of the removable battery 100, and an image is generated for ranking the removable batteries 100. The flow of processing of the unit 340 can be easily understood by considering it in the same way as the flow of processing in the flowchart shown in FIG. Therefore, a detailed description of the ranking process performed by the image generation unit 340 in this case will be omitted.

Further, in the flowchart of the ranking process shown in FIG. 10 , all acquired removable batteries 100 are ranked by receiving a request from the terminal device 400 . However, the ranking of the removable batteries 100 is not limited to the timing after receiving the request from the terminal device 400 . For example, the ranking of the removable batteries 100 is performed at the final timing of the process of updating the charging/discharging station device state table 364 by the management unit 320 or at the timing after the updating of the charging/discharging station device state table 364 is completed. good too. In this case, for example, the management unit 320 gives priority to providing the removable battery 100 with a high SOH (not deteriorating) or a low SOH ( The detachable batteries 100 are ranked according to any condition of giving priority to providing the detachable battery 100 (deteriorating). As a result, the image generation unit 340 can perform the processing from step S150 onwards, assuming that the processing from step S120 to step S140 shown in FIG. 10 has already been completed. At this time, for example, if the management unit 320 is to generate an image showing the positions of the charge/discharge station devices 200 ranked under conditions opposite to the conditions under which the removable batteries 100 were ranked, the image generation unit 340 selects the recommended charging/discharging station device 200 from the lowest ranked charging/discharging station device 200, and generates an image showing the position of the selected charging/discharging station device 200. The flow of processing of the image generator 340 in this case can also be easily conceived based on the flow of processing in the flowchart shown in FIG.

The information (SOC, SOH, temperature, usage status, etc.) for determining the above-described "predetermined state of the removable battery 100" may not be used individually, but may be combined with a plurality of pieces of information. For example, by combining information on the SOC, SOH, temperature, and usage status of the removable battery 100 by the user, it is determined whether or not the removable battery 100 is in a predetermined state, Each removable battery 100 may be ranked.

Note that in the image IM1 shown in FIG. 9, the number shown in the pin mark LB represents the degree of recommendation in each charging/discharging station device 200. As shown in FIG. However, the method of representing the degree of recommendation in each charge/discharge station device 200 may be a method other than the numbers shown in the pin marks LB. Some examples of images IM representing the degree of recommendation in each charging/discharging station device 200 by means other than the number shown in the pin mark LB are shown below.

[Second example of image]
FIG. 11 is a diagram showing another example of an image provided by the management server 300. As shown in FIG. The image IM2 shown in FIG. 11 is an image in which a triangular mark LT is superimposed as an icon representing the position of the terminal device 400 and a pin mark LBC is superimposed as an icon representing the position of each charging/discharging station device 200 in the local map. is an example. In the image IM2, the pin mark LB in the image IM1 shown in FIG. 9 has changed to a pin mark LBC. The pin mark LBC is an icon that indicates the ranking of the degree of recommendation in each charging/discharging station device 200 installed in the local map by the color shading of the pin mark LBC. For example, the image IM2 shows the order of the degree of recommendation in the charging/discharging station devices 200 up to the fourth. The lower charge/discharge station device 200 has a lighter colored pin mark LBC. With this pin mark LBC, in image IM2, information corresponding to the ranking of the recommendation degree can be represented, although the number itself does not represent the ranking of the recommendation degree of charging/discharging station device 200 . By transmitting this image IM2 to the terminal device 400 and displaying it on the display unit 420, the management server 300 recommends replacement of the detachable battery 100 of the charging/discharging station device 200 indicated by the dark pin mark LBC. can be presented to the user as the charging/discharging station device 200. Note that the ranking of the degree of recommendation of each charging/discharging station device 200 may be represented by different colors of the pin marks LBC instead of being represented by the color densities of the pin marks LBC as in the image IM2.

[Third example of image]
FIG. 12 is a diagram showing still another example of the image provided by the management server 300. As shown in FIG. The image IM3 shown in FIG. 12 is an image in which a triangular mark LT is superimposed as an icon representing the position of the terminal device 400 and a pin mark LBS is superimposed as an icon representing the position of each charging/discharging station device 200 in the local map. is an example. In the image IM3, the pin mark LB in the image IM1 shown in FIG. 9 is changed to a pin mark LBS. The pin mark LBS is an icon that indicates, by size, the ranking of the degree of recommendation in each charging/discharging station device 200 installed in the local map. With this pin mark LBS, the image IM3 does not represent the ranking of the degree of recommendation of the charging/discharging station device 200, but represents information corresponding to the ranking of the degree of recommendation, like the image IM2 shown in FIG. can be done. By transmitting this image IM3 to the terminal device 400 and displaying it on the display unit 420, the management server 300 allows the charging/discharging station device 200 with the large pin mark LBS to be charged and recommended to replace the detachable battery 100. It can be presented to the user as the discharge station device 200 .

[Fourth example of image]
FIG. 13 is a diagram showing still another example of the image provided by the management server 300. As shown in FIG. The image IM4 shown in FIG. 13 is an image in which a triangular mark LT is superimposed as an icon representing the position of the terminal device 400 and a pin mark LBF is superimposed as an icon representing the position of each charging/discharging station device 200 in the local map. is an example. In the image IM4, the pin mark LB in the image IM1 shown in FIG. 9 is changed to a pin mark LBF. The pin mark LBF is an icon that indicates the ranking of the degree of recommendation in each charging/discharging station device 200 installed in the local map by different shapes. With this pin mark LBF, in the image IM4, like the image IM2 shown in FIG. 11 and the image IM3 shown in FIG. Information corresponding to ranking can be displayed. By transmitting this image IM4 to the terminal device 400 and displaying it on the display unit 420, the management server 300 can notify the user of the charging/discharging station device 200 that recommends replacement of the removable battery 100 due to the difference in the shape of the pin mark LBF. can be presented to For example, in the image IM4, the star-shaped pin mark LBF has the highest degree of recommendation, the round pin mark LBF, the square pin mark LBF have the lowest recommendation degree, and the triangular pin mark LBF has the highest degree of recommendation. It is presented to the user as the charging/discharging station device 200 having a low recommendation degree.

As described above, according to the management server 300 using the information providing device of the embodiment, the first battery (100) detachable from the moving object (for example, the electric vehicle 10) is replaced with the pre-charged second battery. Acquisition units (310, 320) for acquiring first information (e.g., upload information) indicating the state of the second battery in a facility (200) that provides a service to be exchanged with (100), and a user (user) a providing unit (330, 340) for providing second information (e.g., IM1) to the terminal device (400), the second information presenting a facility where a second battery that can be provided to the user is present. This is information for displaying an image on a display unit (for example, display unit 420) of the terminal device, and the providing unit refers to the first information, and based on the state of the second battery that can be provided to the user, In order to determine the presentation form of the facility (for example, the order of the degree of recommendation), it is possible to actively rent out the detachable batteries that the business operator wants to use for operational reasons.

In the information providing apparatus of the embodiment, the image generating unit 340 included in the management server 300 acquires the local map, and the supplied charged detachable battery 100 installed within the range of the acquired local map is required. The configuration for generating the image IM in which the pin mark LB and the triangular mark LT indicating the positions at which the charging/discharging station devices 200 existing for a few minutes are superimposed and transmitting the image IM to the terminal device 400 has been described. In other words, in the information providing apparatus of the embodiment, the image generation unit 340 included in the management server 300 generates an image to be presented to the user and transmits the image to the terminal device 400 . In the information providing apparatus, the image presented to the user is not limited to the configuration generated by the image generating section 340 included in the management server 300 . For example, an image generation unit (not shown) included in the terminal device 400 generates a local map, and based on the position information of the charging/discharging station device 200 transmitted by the management server 300, within the range of the generated local map A configuration may be employed in which a pin mark LB indicating the position of the charging/discharging station device 200 is superimposed and presented to the user. In this case, the management server 300 receives the request from the terminal device 400 along with the position information of the terminal device 400, and based on the received position of the terminal device 400, the management server 300 is installed within the range of the local map generated by the terminal device 400. The charging/discharging station device 200 is selected, and only the position information of the selected charging/discharging station device 200 is transmitted to the terminal device 400 . Note that the map information when an image generation unit (not shown) included in the terminal device 400 generates the local map is the map information extracted from the map information 366 based on the received position of the terminal device 400, and It may be one sent to the device 400 or one acquired by the terminal device 400 from another server (for example, a map server, not shown) different from the management server 300 .
