Specifically, the BMU 143 generates the power shortage information OE of "with power shortage" when the SOC is less than a predetermined threshold value. Further, the BMU 143 generates the power shortage information OE of "no power shortage" when the SOC is not less than a predetermined threshold value. The BMU 143 stores the generated power shortage information OE in the battery side storage unit 144, and outputs the power shortage information OE to the control device 124.

In this example, the charge state information CGI indicates the SOC of the removable battery 14 mounted on the motorcycle 12. The mobile information generation unit 1241 generates mobile information MBL in which the acquired location information LCI is associated with the charging state information CGI and the power shortage information OE, respectively. The mobile information generation unit 1241 stores the generated mobile information MBL in the storage unit 122. An example of the mobile information MBL generated by the mobile information generation unit 1241 will be described with reference to FIG.

FIG. 3 is a diagram showing an example of the mobile information MBL in the embodiment. The mobile body information MBL is information indicating a correspondence relationship between the location position of the motorcycle 12 and the charged state of the removable battery 14 mounted on the motorcycle 12. As an example, the location information LCI indicates the location of the motorcycle 12 by the global coordinate system (for example, north latitude N and east longitude E). The charge status information CGI is indicated by the ratio of the remaining charge to the full charge capacity of the removable battery 14. The power shortage information OE is "with power shortage" when the ratio of the remaining charge is less than a predetermined threshold value (for example, 10%), and "no power shortage" when it is above the predetermined threshold value. Are shown respectively.

It includes a control unit 167.

The display unit 161 includes, for example, an LCD (Liquid Crystal Display), an organic EL (Electroluminescence) display, a touch panel, and the like, and displays various types of information. For example, the display unit 161 displays an image generated by the station-side control unit 167, and displays a GUI (Graphical User Interface) for receiving various input operations from the operator.

The reading unit 162 is a device (reader) that reads a user ID from an IC card (not shown) carried by the user using, for example, NFC (Near Field Communication). For example, when the IC card is a credit card, the reading unit 162 reads personal information such as a credit number as a user ID. The reading unit 162 outputs the read user ID to the station side control unit 167.

One charging unit 163 is provided in each slot 21, for example. In the charging unit 163, when the connection unit 145 on the removable battery 14 side and the connection unit 164 on the charging station side are electrically or mechanically connected to each other, that is, the removable battery 14 is placed in the slot 21.

Further, the communication unit 165 may transmit information to another device connected via the network NW under the control of the station side control unit 167.
The communication unit 165 may be configured to be able to communicate with the mobile communication unit 123 of the motorcycle 12.

The station-side storage unit 166 is realized by, for example, a ROM, a RAM, an EEPROM, an HDD, a flash memory, or the like. In addition to storing the program, the station-side storage unit 166 stores the user ID of a user (hereinafter referred to as an authenticated user) who is authorized to use the share service of the detachable battery 14. ..

The station-side control unit 167 includes, for example, a charge control unit 1671, a communication control unit 1672, and an authentication unit 1673. This component is realized by executing a program (software) by a processor such as a CPU or GPU (Graphics Processing Unit). In addition, some or all of these components are determined by hardware (including circuit section; circuitry) such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), and FPGA (Field-Programmable Gate Array). It may be realized, or it may be realized by the cooperation of software and hardware. The program may be stored in the station-side storage unit 166 in advance, or is stored in a removable storage medium such as a DVD or a CD-ROM, and the storage medium is mounted on the drive device of the charging station 16. Therefore, it may be installed in the station side storage unit 166.

The charge control unit 1671 acquires information such as the SOC of the removable battery 14 loaded in the slot 21, and controls the charging current supplied to the removable battery 14.

The authentication unit 1673 compares the user ID acquired by the reading unit 162 with the user ID of the authenticated user stored in the station-side storage unit 166, and when the user IDs match each other, the reading unit 162 causes the reading unit 162 to match. It is determined whether or not the owner of the IC card that has read the user ID is an authenticated user. When the owner of the IC card determines that the user is an authenticated user, the authentication unit 1673 causes the display unit 161 to display information indicating that the authentication is successful. In response to this, the user who has the IC card read by the reading unit 162 takes out the charged removable battery 14 from the slot 21 and removes the charged removable battery 14 from the motorcycle 12 when the authentication is successful. The detachable battery 14 is shared by exchanging with the used detachable battery 14 mounted on the. When the used removable battery 14 is loaded in the slot 21, charging is started.

The communication control unit 1672 controls the communication unit 165 to send and receive information to and from the management server 18. For example, the communication control unit 1672 transfers the charge status information CGI transmitted from the motorcycle 12 to the management server 18.

That is, the communication unit 181 is an example of a receiving unit that receives the mobile information MBL transmitted by the transmitting unit of the motorcycle 12.
Further, the communication unit 181 may be configured to be able to receive the mobile information MBL from the motorcycle 12 without going through the charging station 16.

[Charge status map generation process]
Hereinafter, the process of generating the charge state map MP will be described.
FIG. 6 is a diagram showing an example of a charge state map MP generation process by the charge state map generation system 1 of the embodiment.

(Step S110) The mobile information generation unit 1241 of the motorcycle 12 acquires the location information LCI from the GPS 121. This location information LCI indicates the current position of the motorcycle 12.
(Step S120) The mobile information generation unit 1241 acquires the charge state information CGI from the BMU 143. The charge state information CGI indicates the current charge state (for example, the remaining charge amount) of the removable battery 14 mounted on the motorcycle 12.

In this example, the mobile information generation unit 1241 transmits the mobile information MBL when the remaining charge of the removable battery 14 is less than a predetermined remaining amount. Hereinafter, a specific processing example of the mobile information generation unit 1241 will be described.
(Step S130) The mobile body information generation unit 1241 determines whether or not the remaining charge of the removable battery 14 indicated by the charge state information CGI acquired in step S120 is less than a predetermined remaining amount. When the mobile body information generation unit 1241 determines that the remaining charge of the removable battery 14 is not less than the predetermined remaining amount (step S130; NO), the process returns to step S110. When the mobile body information generation unit 1241 determines that the remaining charge of the detachable battery 14 is less than the predetermined remaining amount (step S130; YES), the process proceeds to step S140.
(Step S140) The mobile information generation unit 1241 generates the mobile information MBL by associating the location information LCI acquired in step S110 with the charging state information CGI acquired in step S120. The mobile information generation unit 1241 transmits the generated mobile information MBL to the management server 18 via the mobile communication unit 123 and the network NW.

(Step S210) The information acquisition unit 1831 of the management server 18 receives the mobile information MBL transmitted in step S140 via the network NW and the communication unit 181. The information acquisition unit 1831 stores the received mobile information MBL in the server-side storage unit 182.

A plurality of mobile information MBLs received in the past are stored in the server-side storage unit 182. The mobile body information MBL includes the location information LCI of the motorcycle 12 and the charge status information CGI. In this example, the mobile information MBL is transmitted when the remaining charge of the removable battery 14 is less than a predetermined value. Therefore, the mobile body information MBL indicates a position where the remaining charge of the removable battery 14 mounted on the motorcycle 12 is low, that is, a position where the remaining charge is low 40. FIG. 7 shows an example of the remaining charge low position 40.

FIG. 7 is a diagram showing an example of the charge state map MP of the embodiment. In this example, there are five positions where the remaining charge of the removable battery 14 is reduced, which are the positions 40-a to 40-e where the remaining charge is reduced as shown in FIG. In this case, the information acquisition unit 1831 has acquired the mobile information MBL for the five remaining charge low positions 40-a to 40-e. In the server-side storage unit 182, the mobile information MBL for the remaining charge low position 40-a, the mobile information MBL for the remaining charge low position 40-b, ..., The charge remaining low position 40-e The mobile information MBL and about are stored. That is, the server-side storage unit 182 stores the mobile information MBL for each of the five remaining charge low positions 40.

(Step S220) Returning to FIG. 6, the map generation unit 1832 acquires the mobile information MBL stored in the server-side storage unit 182 in step S210. When a plurality of mobile information MBLs are stored in the server-side storage unit 182, the map generation unit 1832 acquires each of the plurality of mobile information MBLs. The map generation unit 1832 generates a charge state map MP based on the charge state information CGI and the location information LCI included in the acquired mobile body information MBL.
(Step S230) The output unit 184 outputs the charge state map MP generated in step S220 to a presentation device such as a display device (not shown) or a printing device (not shown). FIG. 7 shows an example of the charge state map MP output by the output unit 184.

In the example shown in FIG. 7, the map generation unit 1832 determines the position on the map of the motorcycle 12 whose remaining charge is low (that is, the position 40 where the remaining charge is low) and the position on the map of the charging station 16. A charge state map MP is generated, which is superimposed on the road figure indicated by the map information.
The map generation unit 1832 generates a charge state map MP indicating the positions of the charging stations 16 (charging stations 16-a and 16-b). In addition, the map generation unit 1832 generates a charge state map MP indicating the positions on the map (charge remaining decrease positions 40-a to 40-d) of the motorcycle 12 whose remaining charge is reduced.

[Example of generating charge status map MP (1)]
In this example, the map generation unit 1832 has a low charge position 40 that is relatively close to the position of the charging station 16 and a low charge position that is relatively far from the position of the charging station 16 among the low charge positions 40. Distinguishing from 40, a charging state map MP is generated.
As a specific example, the distance between the remaining charge lowering position 40-e and the charging station 16-a is the distance L1. The distance between the remaining charge lowering position 40-b and the charging station 16-a is a distance L2 that is farther than the distance L1. In the case of this example, the map generation unit 1832 makes the display mode of the remaining charge lowering position 40-e (for example, a broken line) and the display mode of the remaining charge lowering position 40-b (for example, a solid line) different from each other. To generate a charge status map MP.
The cause of the decrease in the remaining charge may be different depending on whether the position 40 where the remaining charge is low is far from the charging station 16 or close to the charging station 16. For example, when the remaining charge lowering position 40 is far from the charging station 16, it can be inferred that the motorcycle 12 cannot reach the charging station 16 and the remaining charge is reduced. On the other hand, when the remaining charge lowering position 40 is close to the charging station 16, the remaining charge is due to another cause (for example, the driver of the motorcycle 12 forgets to charge) even though the charging station 16 can be reached. It can be inferred that the amount has decreased.
As in this example, the map generation unit 1832 is expanded by configuring the display mode of the remaining charge lowering position 40 to be different from each other according to the distance between the remaining charge lowering position 40 and the charging station 16. The position of the charging station 16 to be used can be presented more accurately.

[Example of generating charge status map MP (2)]
As shown in FIG. 7, the map generation unit 1832 may present the remaining charge low area OEA on the charge state map MP. This remaining charge low area OEA indicates a range in which the density of the remaining charge low position 40 is high in the range in the map indicated by the charge state map MP. In this example, the remaining charge low area OEA includes the remaining charge low positions 40-b to 40-d.

[Example of generating charge status map MP (3)]
The map generation unit 1832 does not show all of the plurality of charge remaining amount reduction positions 40 indicated by the mobile information MBL stored in the server-side storage unit 182 in the charge state map MP, but rather displays the plurality of charge remaining amount reduction positions 40. A part of them may be configured as shown in the charge status map MP.
For example, the map generation unit 1832 may refer to the remaining charge low position 40, which is relatively close to the position of the charging station 16, among the remaining charge low positions 40 indicated by the mobile information MBL stored in the server-side storage unit 182. It can be configured not to be presented on the charge status map MP. That is, the map generation unit 1832 presents the remaining charge low position 40, whose position on the map is relatively far from the position of the charging station 16, to the charge state map MP among the remaining charge low positions 40, and presents the position on the map to the charge state map MP. Can be configured not to present to the charge state map MP about the charge remaining amount drop position 40, which is relatively close to the position of the charge station 16.
Here, when the remaining charge low position 40 is relatively close to the position of the charging station 16, the motorcycle 12 reaches the charging station 16 before the remaining charge is 0 (zero), that is, it becomes impossible to travel. You may be able to do it. On the other hand, when the remaining charge lowering position 40 is relatively far from the position of the charging station 16, the motorcycle 12 may have a remaining charge of 0 (zero) before reaching the nearest charging station 16. be. In the case of this example, among the remaining charge lowering positions 40, the charging remaining charge lowering position 40, which is relatively far from the charging remaining amount lowering position 40, which is relatively close to the position of the charging station 16, is the charging station to be added. The 16 positions are shown more appropriately.
By configuring so as not to present the remaining charge low position 40 which is relatively close to the position of the charging station 16 as in this example, the map generation unit 1832 presents the position of the charging station 16 to be added more accurately. be able to.

[Modification example]
FIG. 8 is a diagram showing a modified example of the generation process of the charge state map MP by the charge state map generation system 1. FIG. 8 is different from the example shown in FIG. 6 in that the mobile body information MBL is transmitted from the motorcycle 12 to the management server 18 via the charging station 16.
More specifically, the mobile information MBL is stored in the storage unit 122 of the motorcycle 12, and when the motorcycle 12 arrives at the charging station 16, the mobile information is transmitted via the communication unit 165 of the charging station 16. It differs from the process shown in FIG. 6 in that the MBL is transmitted to the management server 18.
Since the processing contents of each step of steps S110 to S130 and steps S210 to S230 are the same as those of step S having the same reference numerals as shown in FIG. 6 described above, the description thereof will be omitted.

(Step S140) The mobile information generation unit 1241 stores the generated mobile information MBL in the storage unit 122.
(Step S150) The control device 124 of the motorcycle 12 determines whether or not the motorcycle 12 has arrived at the charging station 16. As a specific example, the control device 124 determines that the motorcycle 12 has arrived at the charging station 16 when the communication with the charging station 16 is possible via the mobile communication unit 123.
When the control device 124 determines that the motorcycle 12 has not arrived at the charging station 16 (step S150; NO), the process returns to step S110. When the control device 124 determines that the motorcycle 12 has arrived at the charging station 16 (step S150; YES), the process proceeds to step S160.

(Step S160) The control device 124 transmits the mobile information MBL stored in the storage unit 122 to the charging station 16 via the mobile communication unit 123.
(Step S310) The communication unit 165 of the charging station 16 receives the mobile information MBL transmitted by the motorcycle 12, and transmits the received mobile information MBL to the management server 18. That is, the communication unit 165 transfers the mobile information MBL transmitted by the motorcycle 12 to the management server 18.
(Steps S210 to S230) In the same manner as the process shown in FIG. 6 described above, the management server 18 generates a charge state map MP and outputs the generated charge state map MP.

According to the embodiment described above, the charge state map generation system 1 presents the charge state map MP. The charge state map MP shows a position where the remaining charge of the removable battery 14 mounted on the motorcycle 12 is low, that is, a position 40 where the remaining charge is low. Since the removable battery 14 is charged at the charging station 16, the remaining charge low position 40 indicates that the charging station 16 should be added in the vicinity thereof.
Therefore, according to the charging state map generation system 1 of the embodiment, it is possible to provide information for examining the area where the charging station should be installed.

Further, according to the above-described embodiment, the map generation unit 1832 indicates on the map the location of the motorcycle 12 in which the remaining charge of the attached removable battery 14 is less than a predetermined amount. Generates the charge status map MP shown in. More specifically, when the power deficiency information OE included in the moving body information MBL transmitted from the motorcycle 12 indicates "there is a power deficiency", the map generation unit 1832 automatically transmits the power deficiency information OE. The location of the motorcycle 12 is shown in the charge status map MP. According to the charge state map generation system 1 configured in this way, the remaining charge of the detachable battery 14 is binarized into “without power shortage” and “with power shortage”. Based on the remaining charge of the binarized removable battery 14, the map generation unit 1832 indicates that the remaining charge of the attached removable battery 14 is less than the predetermined remaining amount among the motorcycles 12. A charge state map MP showing the location of the only motorcycle 12 on the map is generated.
Here, when the remaining charge of the detachable battery 14 is not binarized into "without power shortage" and "with power shortage", for example, the remaining charge of the removable battery 14 is displayed in the charge status map MP. Even when the amount rate is presented on the charge state map MP, or when the remaining charge is relatively large, a situation may occur in which the remaining charge lower position 40 is presented on the charge state map MP. In this case, the information presented on the charging status map MP becomes complicated, which may hinder the examination of the area where the charging station should be installed. According to the charge state map generation system 1 of the embodiment, among the positions where the remaining charge of the removable battery 14 is low, the position determined to be "insufficient" is presented to the charge state map MP, and the charge state map is presented. Since the content presented to the MP is simplified, it is possible to provide a charging status map MP that makes it easier to consider the area where the charging station should be installed.

Further, according to the above-described embodiment, the map generation unit 1832 generates a charging state map MP in which the position of the charging station 16 is presented on the map. According to the charging state map generation system 1 configured in this way, it is possible to easily grasp the area where the installation density of the charging station 16 is relatively low on the map.

Further, according to the above-described embodiment, the mobile body information generation unit 1241 transmits the mobile body information MBL when the remaining charge of the removable battery 14 indicated by the charge state information CGI is less than a predetermined remaining amount. .. That is, when the remaining charge of the removable battery 14 indicated by the charge status information CGI is not less than the predetermined remaining amount, that is, when the remaining charge of the detachable battery 14 is relatively large, the mobile body information generation unit 1241 Do not send mobile information MBL. According to the charge state map generation system 1 configured in this way, the frequency with which the motorcycle 12 transmits the mobile information MBL can be reduced, the communication amount of the network NW can be reduced, and the motorcycle 12 can be controlled. The power consumption of the device 124 can be reduced.

Further, according to the above-described embodiment, the motorcycle 12 transmits the mobile information MBL to the management server 18 via the charging station 16. Here, when the motorcycle 12 communicates with the management server 18 without going through the charging station 16, the motorcycle 12 needs to have a connection function to a public communication network such as a mobile phone communication network. According to the charging state map generation system 1 of the embodiment, the motorcycle 12 may communicate with the charging station 16, and even if the motorcycle 12 does not have a connection function to the public communication network, the mobile information MBL Can be sent to the management server 18. That is, according to the charge state map generation system 1 of the embodiment, the configuration of the communication function of the motorcycle 12 can be simplified.

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.
