In this image, a graphic such as an icon indicating the degree to which the charge / discharge station device 200 is recommended to the user (hereinafter, the recommended degree) is arranged at a position where each charge / discharge station device 200 is installed. Therefore, the image generation unit 340 ranks the charged removable batteries 100 existing in the charge / discharge station device 200 according to a predetermined condition, and ranks the charge / discharge station device 200 in which the detachable battery 100 having a higher rank is present. Select and generate an image in which the user can recognize the position where the selected charge / discharge station device 200 is installed. The "predetermined condition" is, for example, that at least the required number of charged batteries is required and the removable battery 100 satisfies the predetermined state. The "predetermined state of the removable battery 100" can be determined based on, for example, the SOC, SOH, temperature, and the like of the removable battery 100.

Here, the method for determining the "predetermined state of the detachable battery 100" may be determined by, for example, a business operator who provides a replacement service for the removable battery 100 in the charge / discharge station device 200. In this case, the business operator that provides the replacement service should recommend the removable battery 100 in a state in which the user wants the user to actively use the battery, depending on the intention of the business operator, for example, for operational reasons. You will be able to control it.

For example, when determining the "predetermined state of the removable battery 100" based on the SOC, each removable battery 100 can be ranked according to the length of time elapsed from the completion of charging obtained from the SOC. In this case, for example, the longer the elapsed time from the completion of charging, the more the detachable battery 100 tends to be determined to be in a predetermined state, and each detachable battery 100 is determined. Can be preferentially rented out. As a result, as with a general storage battery, the operator can deteriorate the removable battery 100, which progresses as the elapsed time from the completion of charging (the longer the time in which the battery is fully charged) increases. It is possible to provide a replacement service for the removable battery 100 with less operation. In other words, it is possible to provide a replacement service for the removable battery 100 in an operation in which the removable battery 100 is used as much as possible after charging is completed.

Further, for example, when determining the "predetermined state of the removable battery 100" based on the SOH, each removable battery 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 degree of deterioration is less, and the detachable battery 100 closer to a new one is preferentially lent out. Can be. As a result, the business operator can provide a replacement service for the removable battery 100 in an operation in which the degree of deterioration of each removable battery 100 is uniform. As a result, the operator reduces the frequency of maintenance for replacing the deteriorated and unusable removable battery 100 with a new one, and replaces all the removable batteries 100 with new ones at the same time. Such as, maintenance work can be facilitated. On the contrary, for example, as the deterioration progresses, each detachable battery 100 is determined with a tendency to determine that the removable battery 100 is in a predetermined state, and the deterioration progresses (however, it cannot be used). It is also possible to preferentially rent out the removable battery 100 (which has not deteriorated to a certain level). As a result, the operator makes the progress of deterioration of each of the removable batteries 100 uneven, that is, the plurality of removable batteries 100 deteriorate at the same time and become unusable. It is possible to provide a replacement service for the removable battery 100 in an operation that avoids it. As a result, the operator averages the frequency of maintenance to replace the deteriorated and unusable removable battery 100 with a new one, and replaces the removable battery 100 with a new one in one maintenance operation. It is possible to reduce the cost required for maintenance work, such as reducing the number of 100. When determining the "predetermined state of the removable battery 100" based on the SOH, the comparison of the degree of deterioration of each removable battery 100 is set in the area in the image generated by the image generation unit 340. It may be performed for all the removable batteries 100 existing in all the charge / discharge station devices 200, or may be performed for all the removable batteries 100 existing in the same charge / discharge station device 200.

Further, for example, when determining the "predetermined state of the removable battery 100" based on the temperature, each removable battery 100 can be ranked according to the temperature of the removable battery 100. In a general storage battery, the reaction in the storage battery tends to deteriorate in a temperature range called low temperature (for example, 15 ° C. or lower), and the output capacity tends to decrease. On the contrary, 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 determining the "predetermined state of the removable battery 100" based on the temperature, for example, the removable battery 100 whose temperature is within the range of the predetermined value (for example, 20 ° C. or higher and 40 ° C. or lower) is set to the predetermined state. Each detachable battery 100 can be determined based on the tendency to determine that the battery 100 is present, and the detachable battery 100 whose temperature is within a predetermined value range can be preferentially rented out. As a result, the operator can reduce the output capacity due to the low temperature, reduce the efficiency of the power supply due to the high temperature, or reduce the efficiency, similar to a general storage battery. It is possible to provide a replacement service for the detachable battery 100 in an operation in which the battery 100 is less likely to be rented out. "The efficiency of power supply decreases due to high temperature" means that, for example, the power supply decreases due to a safety function that suppresses the temperature rise of the removable battery 100 by reducing the power supplied when the temperature rises. Also includes. When determining the "predetermined state of the removable battery 100" based on the temperature, the temperature of each removable battery 100 may be determined based on the current temperature, or the user may use the charge / discharge station device. It may be done in consideration of the time of arrival at 200, that is, based on the temperature at which the removable battery 100 is actually rented.

The determination of the "predetermined state of the removable battery 100" is made, for example, when the usage status of the removable battery 100 by the user who requested the replacement of the removable battery 100 is recorded in the user information management table 362. It may be performed in consideration of the usage situation. For example, a user who requests replacement of the removable battery 100 replaces the removable battery 100 as soon as possible, in other words, the removable battery 100 has a charge remaining (the SOC has not dropped to a level requiring replacement). ), Even if the user does not have the detachable battery 100 in the fully charged state, the detachable battery 100 having an SOC of a predetermined value or more can be rented out. In this case, the standard of the SOC value in the determination of the "predetermined state of the removable battery 100" based on the SOC is a predetermined value (for example, the SOC is 100%) lower than the fully charged value (for example, the value of the SOC is 100%). The value is 80%), and the removable battery 100 having a predetermined value or more may be the target of the determination. Then, for example, each removable battery 100 may be ranked so that the removable battery 100 having a SOC value of 80% has the highest rank. Further, for example, when the user who requested the replacement of the removable battery 100 is a user who tends to replace the removable battery 100 after using the battery until there is almost no charge remaining, the position of the user (more specifically). Specifically, the detachable battery 100 located closer to the position of the terminal device 400) may be rented out. 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 is a value of 100%), and the removable battery 100 closest to the user's current position is the most. Each removable battery 100 may be ranked so as to have a higher rank. It should be noted that the usage status of the removable battery 100 by the user can be examined by, for example, machine learning, deep learning, AI (Artificial Intelligence), etc., and the tendency of the user to use the removable battery 100 and the tendency of the replacement timing of the removable battery 100. It may be used as data for learning such as.

The process of determining the "predetermined state of the removable battery 100", the process of ranking the detachable battery 100, and the process of selecting the charge / discharge station device 200 in which the detachable battery 100 having a higher rank exists are image generation. A component other than the unit 340 may be used, and the image generation unit 340 may be configured to only generate an image in which the user can 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. 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 charge / discharge station device 200 in the local map. This is an example. In the image IM1, the rank of the removable battery 100 is represented by the pin mark LB on which the number representing the rank is shown, which is ranked according to a predetermined condition. For example, in the image IM1, the position of the charge / discharge station device 200 in which the removable battery 100 up to the fourth rank exists is shown. By transmitting this image IM1 to the terminal device 400 and displaying it on the display unit 420, the management server 300 charges and discharges a removable battery 100 having a small number (higher rank) shown in the pin mark LB. The station device 200 can be presented to the user as a charge / discharge station device 200 that recommends replacement of the removable battery 100. The number indicated by the pin mark LB is not limited to the value of the order of the removable battery 100 itself. For example, when 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, the order in which the charge / discharge station device 200 is ranked based on the order of the top two removable batteries 100 existing in each charge / discharge station device 200 may be represented by the numbers shown in the pin mark LB. For example, the order of each removable battery 100 may be scored, and the charge / discharge station device 200 may be ranked in ascending order of the total score of the top two removable batteries 100. In other words, the degree of recommendation may be comprehensively determined, and the ranking may be represented by a number indicated by a pin mark LB.

For example, when a plurality of charge / discharge station devices 200 with a high degree of recommendation are installed nearby, pin marks LB indicating 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 is displayed in front of the pin mark LB of the charge / discharge station device 200 with a higher recommendation level, and is displayed in the back of the pin mark LB of the charge / discharge station device 200 with a lower recommendation level (in other words). For example, it is displayed so as to be hidden behind the pin mark LB in the foreground). In the image IM1, of the two charge / discharge station devices 200 in the region R1, the charge / discharge station device 200 whose recommended degree rank is indicated by the first pin mark LB is represented in the foreground, and the recommended degree rank is the fourth. Indicates a state in which the charge / discharge station device 200 indicated by the pin mark LB is hidden.

[Ranking process]
Here, the ranking process of the detachable battery 100 performed when the image generation unit 340 generates an image will be described. The ranking of the removable batteries 100 in the image generation unit 340 is performed based on the required number of charged batteries in the electric vehicle 10 and a predetermined state of the removable batteries 100 based on, for example, SOC, SOH, temperature, and the like. .. In the following description, in order to facilitate the 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. , Each detachable battery 100 shall be ranked. Then, the order of the detachable battery 100 indicates the recommended degree of the charge / discharge station device 200 recommended to the user.

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

When the site providing unit 330 outputs information indicating that the request from the terminal device 400 has been received, the image generation 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 applies the battery information (here, SOH information) of the removable battery 100 in each charge / discharge station device 200 installed within the range of the acquired local map to the charge / discharge station device. Obtained from the state table 364 (step S110).

Subsequently, the image generation unit 340 confirms whether or not to give priority to the provision of the removable battery 100 having a high SOH as the recommended degree of recommending the charge / discharge station device 200 to the user (step S120). In other words, preferentially lend out the removable battery 100 that has deteriorated (however, it has not deteriorated to an unusable level), or the degree of deterioration is less (more new). (Near) Confirm whether to preferentially lend the removable battery 100. Whether to preferentially rent out the detachable battery 100 that is deteriorating or to preferentially rent out the detachable battery 100 that is less deteriorated is a replacement service for the detachable battery 100. Is determined in advance by the business operator that provides the above, and is set in the management server 300 or the image generation unit 340.

When it is confirmed in step S120 that priority is given to the provision of the removable battery 100 having a high SOH (deterioration has not progressed), the image generation unit 340 has acquired each removable battery in descending order of the SOH value. The 100 are ranked (step S132).

On the other hand, in step S120, the provision of the removable battery 100 having a high SOH (deterioration has not progressed) is not prioritized, that is, the provision of the removable battery 100 having a low SOH (deterioration has progressed) is prioritized. When the above is confirmed, the image generation unit 340 ranks the acquired removable batteries 100 in ascending order of the 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 generation unit 340 proceeds to the process in step S120. Then, the image generation unit 340 repeats the ranking process (processes of steps S120 to S140) for each of the acquired removable batteries 100.

On the other hand, when it is determined in step S140 that the ranking of all the acquired removable batteries 100 has been completed, the image generation unit 340 attaches / detaches in a higher order based on the ranking of each of the ranked removable batteries 100. The charge / discharge station device 200 with the formula battery 100 is selected (step S150).

Subsequently, the image generation unit 340 displays a pin mark LB showing a number indicating the rank (recommended degree) in the selected charge / discharge station device 200 in the acquired local map, and each corresponding charge / discharge station device 200. An image superimposed on the position of is generated (step S160). The image generation unit 340 superimposes the pin mark LB of each charge / discharge station device 200 and superimposes the triangular mark LT on the position of the terminal device 400 in the local map. Then, the image generation unit 340 ends the processing of this flowchart.

In this way, the image generation unit 340 generates the image IM1 as shown in FIG. 9, and outputs the generated IM1 to the site providing unit 330. Then, the site providing unit 330 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 included in the terminal device 400, and information on the recommended degree of each charge / discharge station device 200 is presented to the user. Then, the user may select the charge / discharge station device 200 to replace the removable battery 100 based on the information on the recommended degree of each of the presented charge / discharge station devices 200, and go to the selected charge / discharge station device 200. it can.

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

In the flowchart of the ranking process shown in FIG. 10, each removable battery 100 was 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 battery 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 battery 100 may be ranked. In this case, an image generation that determines the "predetermined state of the removable battery 100" in consideration of the SOC and temperature of the removable battery 100 and the usage status of the removable battery 100 by the user, and ranks the removable battery 100. The processing flow of part 340 can be easily understood by considering the same as the processing flow 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 the acquired removable batteries 100 are ranked by receiving the request from the terminal device 400. However, the ranking of the removable battery 100 is not limited to the timing after receiving the request from the terminal device 400. For example, the detachable battery 100 is ranked at the final timing of the process in which the management unit 320 updates the charge / discharge station device status table 364 or at the timing after the update of the charge / discharge station device status table 364 is completed. May be good. In this case, for example, the management unit 320 gives priority to the provision of the removable battery 100 having a high SOH (deterioration has not progressed) or has a low SOH (as a recommendation degree for recommending the charge / discharge station device 200 to the user). The removable battery 100 is ranked according to any condition that gives priority to the provision of the removable battery 100 (which is in progress of deterioration). As a result, the image generation unit 340 can perform the processing after step S150, assuming that the processing of steps S120 to S140 shown in FIG. 10 has already been completed. At this time, for example, when the management unit 320 is to generate an image showing the position of the charge / discharge station device 200 ranked under the condition opposite to the condition in which the detachable battery 100 is ordered, the image generation unit 340 Reverses the order ranked by the management unit 320, that is, selects the recommended charge / discharge station device 200 from the one with the lowest order, and generates an image showing the position of the selected charge / discharge station device 200. Since the processing flow of the image generation unit 340 in this case can be easily considered based on the processing flow in the flowchart shown in FIG. 10, detailed description thereof will be omitted.

Note that the information (SOC, SOH, temperature, usage status, etc.) for determining the above-mentioned "predetermined state of the removable battery 100" may be a combination of a plurality of information, not information used individually. For example, the SOC, SOH, temperature, and usage status of the removable battery 100 by the user are combined to determine whether or not the removable battery 100 is in a predetermined state. Each removable battery 100 may be ranked.

In the image IM1 shown in FIG. 9, the recommended degree in each charge / discharge station device 200 was indicated by the numbers shown in the pin mark LB. However, the method for expressing the recommended degree in each charge / discharge station device 200 may be a method other than the numbers shown in the pin mark LB. Below are some examples of image IMs that represent the degree of recommendation in each charge / discharge station device 200 by means other than the numbers shown in the pin mark LB.

[Second example of image]
FIG. 11 is a diagram showing another example of the image provided by the management server 300. 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 charge / discharge station device 200 in the local map. This is an example. In the image IM2, the pin mark LB in the image IM1 shown in FIG. 9 is changed to the pin mark LBC. The pin mark LBC is an icon indicating the order of the recommended degree in each charge / discharge station device 200 installed in the local map by the shade of color of the pin mark LBC. For example, in the image IM2, the order of the recommended degree in the charge / discharge station device 200 is shown up to the fourth, but the charge / discharge station device 200 having the higher recommended degree has a darker pin mark LBC, and the order of the recommended degree is higher. The lower charge / discharge station device 200 has a lighter color pin mark LBC. With this pin mark LBC, the image IM2 can represent information corresponding to the rank of the recommended degree, although it is not the number itself indicating the rank of the recommended degree of the charge / discharge 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 that the charge / discharge station device 200 indicated by the dark pin mark LBC be replaced with the removable battery 100. It can be presented to the user as the charging / discharging station device 200. The order of the recommended degree of each charge / discharge station device 200 may be expressed by making the color of the pin mark LBC different, instead of expressing it by the shade of the color of the pin mark 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. 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 charge / discharge station device 200 in the local map. This is an example. In the image IM3, the pin mark LB in the image IM1 shown in FIG. 9 is changed to the pin mark LBS. The pin mark LBS is an icon indicating the rank of the recommended degree in each charge / discharge station device 200 installed in the local map. By this pin mark LBS, the image IM3, like the image IM2 shown in FIG. 11, is not the number itself indicating the order of the recommended degree of the charge / discharge station device 200, but represents the information corresponding to the order of the recommended degree. 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 recommends that the charge / discharge station device 200 having a large pin mark LBS be replaced with the removable battery 100. It can be presented to the user as a 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. 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 charge / discharge station device 200 in the local map. This is an example. In the image IM4, the pin mark LB in the image IM1 shown in FIG. 9 is changed to the pin mark LBF. The pin mark LBF is an icon indicating the order of the recommended degree in each charge / discharge station device 200 installed in the local map by a difference in shape. Due to this pin mark LBF, in the image IM4, like the image IM2 shown in FIG. 11 and the image IM3 shown in FIG. 12, it is not the number itself indicating the order of the recommended degree of the charge / discharge station device 200, but the recommended degree. Information corresponding to the ranking can be represented. By transmitting this image IM4 to the terminal device 400 and displaying it on the display unit 420, the management server 300 uses the charge / discharge 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 recommendation level, the round pin mark LBF and the square pin mark LBF have the lowest recommendation level, and the triangular pin mark LBF has the highest recommendation level. It is presented to the user as a charge / discharge 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) that can be attached to and detached from the moving body (for example, the electric vehicle 10) is precharged with the second battery. Acquiring units (310, 320) for acquiring first information (for example, upload information) indicating the state of the second battery in a facility (200) that provides a service for exchanging with (100), and a user (user). The terminal device (400) is provided with a providing unit (330, 340) that provides second information (for example, IM1), and the second information presents a facility in which a second battery that can be provided to the user exists. Information for displaying an image on a display unit (for example, display unit 420) of a terminal device, the providing unit refers to the first information and is 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 recommendation degree), it is possible to actively rent out the removable battery that the operator wants to use for operational reasons.

The information providing device of the embodiment requires an image generation unit 340 included in the management server 300 to acquire a local map, and a rechargeable removable battery 100 that can be provided and is installed within the range of the acquired local map. The configuration of generating an image IM on which the pin mark LB and the triangular mark LT indicating the positions where the charge / discharge station devices 200 existing for several minutes are installed and transmitting them to the terminal device 400 has been described. That is, in the information providing device of the embodiment, the configuration in which the image generation unit 340 included in the management server 300 generates an image to be presented to the user and transmits it to the terminal device 400 has been described. In the information providing device, the image presented to the user is not limited to the configuration generated by the image generation unit 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 charge / discharge station device 200 transmitted by the management server 300, the local map is within the range of the generated local map. The pin mark LB indicating the position of the charge / discharge station device 200 may be superimposed and presented to the user. In this case, the management server 300 receives information on the position of the terminal device 400 together with a request from the terminal device 400, and is installed within the range of the local map generated by the terminal device 400 based on the received position of the terminal device 400. The charge / discharge station device 200 is selected, and only the position information of the selected charge / discharge station device 200 is transmitted to the terminal device 400. As for the map information when the image generation unit (not shown) included in the terminal device 400 generates a local map, the management server 300 terminals the map information cut out from the map information 366 based on the position of the received terminal device 400. It may be transmitted to the device 400, or may be acquired by the terminal device 400 from another server (for example, a map server, etc .: not shown) different from the management server 300.

Although the embodiments for carrying out the present invention have been described above using the embodiments, the present invention is not limited to these embodiments, and various modifications and substitutions are made without departing from the gist of the present invention. Can be added.
