(1) Outline of Embodiment (1-1) FIG. 1 shows a management system 10 of one embodiment. The management system 10 is a system that manages the use of one or more mobile bodies 100 by one or more users. In particular, in the present embodiment, it is assumed that the management system 10 is a system that manages the use of a plurality of mobile objects 100 (100A to 100D) by a plurality of users. The management system 10 manages a plurality of mobile bodies 100 so that each user can use the mobile body 100 that meets the user's request (request, desire). The term "use" as used herein may include a use that does not require payment of a fee and a use that requires payment of a fee. For example, if the plurality of mobiles 100 are the property of a company and a user who is an employee of the company uses the mobile 100, no fee is required to be paid. On the other hand, when the company permits a user who is not an employee of the company to use the mobile body 100, that is, rents the mobile body 100, the user who is not an employee of the company pays for the use of the mobile body 100.

In the present embodiment, the mobile body 100 has a storage battery 110 used as a power source for the mobile body 100 (see FIG. 1). The storage battery (battery) 110 is used to drive a driving device (for example, a motor) of the mobile body 100. As an example, the mobile body 100 is an electric vehicle that travels using the electric energy stored in the storage battery 110. Examples of the electric vehicle include an electric vehicle that travels by the output of the electric motor, or a plug-in hybrid vehicle that travels by combining the output of the engine and the output of the electric motor. That is, an electric vehicle can mean an electric vehicle (meaning a vehicle that uses electricity as all or part of a power source). The moving body 100 is not limited to the electric vehicle, and may be a senior car, a two-wheeled vehicle (electric motorcycle), a three-wheeled vehicle, or an electric bicycle. In the following, for the sake of clarity, the moving body 100 is assumed to be an electric vehicle, and the moving body 100 is referred to as an electric vehicle 100, if necessary.

The management system 10 can be applied to a car sharing service or a rental car service as an example. In particular, in the present embodiment, the management system 10 can be used to provide a service of renting a vehicle owned by a corporation such as a company to a user. In this case, the user is not limited to a person (employee, etc.) belonging to the corporation, but may also include a person not belonging to the corporation. That is, the management system 10 can also be applied to a service of renting a vehicle that a person (employee, etc.) belonging to the corporation does not plan to use to a person who does not belong to the corporation.

As shown in FIG. 1, the management system 10 includes a charge management system 20, a usage management system 30, a power supply system 40, and a terminal device 50.

The request from the user is sent to the usage management system 30, and the usage management system 30 gives the request information to the charge management system 20 according to the request from the user (M12). The request information includes, for example, information regarding the required period of use of the electric vehicle 100. The charge management system 20 generates determination information based on the available electric energy of the storage battery 110 in the required period of the electric vehicle 100 obtained from the usage schedule and the required information of the plurality of electric vehicles 100 (S11). The determination information is information for determining whether or not there is an electric vehicle 100 that can be used in the required period among the plurality of electric vehicles 100. The charge management system 20 gives determination information to the use management system 30 (M13). The usage management system 30 determines whether or not the electric vehicle 100 can be used (that is, determines whether or not there is an electric vehicle 100 that matches the request from the user) by referring to the request from the user and the determination information. (S12). Then, if there is one or more usable electric vehicles 100, the usage management system 30 transmits information about the usable one or more electric vehicles 100 to the terminal device 50, and the usable one or more electric vehicles 100. Is presented to the user (M14). When the user selects the electric vehicle 100 desired to be used from one or more available electric vehicles 100 by the terminal device 50, the information of the electric vehicle 100 selected by the user is sent to the usage management system 30 (M15). In response to this, the usage management system 30 confirms the use of the electric vehicle 100 selected by the user, and notifies the terminal device 50 and the charge management system 20 that the use of the electric vehicle 100 is confirmed (M16, M17). Then, the usage management system 30 updates the usage schedule for the plurality of electric vehicles 100 (S13). Further, the charge management system 20 updates the charge schedule for the plurality of electric vehicles 100 (S14).

The reception unit 331 of the usage management system 30 receives the user's request regarding the mobile body 100 from the terminal device 50. The user's request for the electric vehicle 100 includes at least a request for the required period of use of the electric vehicle 100. The request period is a period during which the user requests the use of the electric vehicle 100. The user's request regarding the electric vehicle 100 may include the user's attribute information and the attribute information of the electric vehicle 100. The user attribute information can be information about whether or not the user belongs to a corporation. Further, the attribute information of the electric vehicle 100 may include at least one of a type, an application, an initial position, a destination, a planned travel distance, a planned number of people to travel, and a mode of use.

The determination unit 332 of the usage management system 30 determines whether or not there is an electric vehicle 100 that meets the user's request regarding the electric vehicle 100. In the present embodiment, the determination unit 332 selects the electric vehicle 100 that meets the user's request from the plurality of electric vehicles 100. The determination unit 332 refers to the determination information obtained from the charge management system 20 when selecting the electric vehicle 100 that meets the user's request from the plurality of electric vehicles 100. The determination unit 332 gives request information to the charge management system 20 in order to obtain determination information from the charge management system 20. The request information includes information regarding the required period of use of the electric vehicle 100. In the present embodiment, the required information includes information on the amount of electric power required to use the electric vehicle 100 for the required period. Here, the user's request regarding the electric vehicle 100 may include the user's attribute information and the attribute information of the electric vehicle 100. The attribute information of the electric vehicle 100 may include at least one of a type, an application, an initial position, a destination, a planned travel distance, a planned number of people to travel, and a mode of use. Examples of the types include the vehicle type of the electric vehicle 100 and the type of the electric vehicle 100 (ordinary vehicle, light vehicle, etc.). Examples of uses include travel, shopping, transportation, delivery and the like. An example of the initial position is a place where the electric vehicle 100 is placed at the beginning of the planned use period. This place may be a charging place of the electric vehicle 100. An example of a destination is a place where a user visits using the electric vehicle 100. For example, when the user uses the electric vehicle 100 for shopping, the store visited by the user is the destination. Further, when the user uses the electric vehicle 100 for a trip, the tourist destination or the accommodation facility visited by the user is the destination. The planned travel distance is the distance that the user plans to travel by the electric vehicle 100. For example, the distance required for the round trip between the initial position and the destination is the planned travel distance. The number of people scheduled to move is the number of people scheduled to move by the electric vehicle 100. As an example, the number of people scheduled to move is the number of people scheduled to ride in the electric vehicle 100. The usage mode is the usage mode of the electric vehicle 100. Here, as the usage mode, it is assumed that the usage mode is used by employees of the company (use in business) and the usage mode is used by non-employees of the company (use outside business, car sharing and rental car).

The determination unit 332 may obtain the required electric energy from the attribute information of the electric vehicle 100. For example, if the attribute information of the electric vehicle 100 includes the planned travel distance, the required electric energy can be estimated from the planned travel distance. In addition, the planned travel distance may be estimated from the initial position or the destination. For example, the type of the electric vehicle 100 and the number of people scheduled to move may affect the electric cost of the electric vehicle 100. Electricity costs can affect the amount of electricity required. Therefore, the required electric energy may be changed according to the type of the moving body (electric vehicle 100). Further, the required electric energy may be changed according to the use of the mobile body (electric vehicle 100). Examples of applications of the electric vehicle 100 include travel, shopping, and the like. Since travel is expected to travel a longer distance than shopping, if the purpose is travel, the required amount of electric power can be set more than when the purpose is shopping. Further, the request information may include the user's attribute information and the attribute information of the electric vehicle 100 included in the user's request regarding the electric vehicle 100. That is, the required electric energy does not necessarily have to be the electric energy required to operate (run) the electric vehicle 100 during the required period, and is set in consideration of various conditions such as attribute information of the electric vehicle 100. Can be done.

The acquisition unit 231 of the charge management system 20 receives request information including information on a request period for use of the electric vehicle 100 from the use management system 30 that manages the use of a plurality of electric vehicles 100 each having a storage battery 110 used as a power source. get. In the present embodiment, the determination unit 332 of the usage management system 30 transmits the request information to the charge management system 20, and the acquisition unit 231 of the charge management system 20 receives the request information through the communication network 60. In addition, the acquisition unit 231 acquires the usage schedule of the electric vehicle 100 from the usage management system 30. At this time, the acquisition unit 231 also acquires information on the planned usage amount of the scheduled usage period included in the usage schedule from the usage management system 30.

The presentation unit 232 of the charge management system 20 presents the determination information to the usage management system 30. The determination information is information for determining whether or not the electric vehicle 100 can be used during the required period. The presentation unit 232 generates determination information based on the amount of available electric power of the storage battery 110 during the required period of the electric vehicle 100. In the present embodiment, the determination information includes basic information. The basic information includes information indicating the amount of available electric power (first available amount of electric power) in the required period of the electric vehicle 100. In addition, the determination information includes impact information as necessary. The impact information is information indicating the impact on the use of the electric vehicle 100 in one or more scheduled usage periods when the usable electric energy (first available electric energy) of the storage battery 110 in the required period is secured. In particular, the impact information is the available electric energy of the storage battery 110 (second available electric energy) in one or more planned usage periods when the available electric energy of the storage battery 110 in the required period (first available electric energy) is secured. ) Is included. In this way, the presentation unit 232 can include the basic information and the influence information in the determination information and present them to the usage management system 30.

The determination unit 332 of the usage management system 30 uses the determination information obtained from the presentation unit 232 of the charge management system 20 to determine whether or not there is an electric vehicle 100 that matches the user's request regarding the electric vehicle 100. The determination unit 332 sets the electric vehicle 100 in the required period in which the available electric power amount (first available electric power amount) of the electric vehicle 100 is equal to or larger than the required electric power amount required to use the electric vehicle 100 for the required period. It is selected as a candidate for 100 usable moving bodies (electric vehicles). However, even if the first available electric energy is equal to or greater than the required electric energy, if the second available electric energy is less than the planned usage amount, it is better not to enable the electric vehicle 100 during the required period. Therefore, the determination unit 332 determines that the moving body (electric vehicle) 100 in which the second available electric energy in the planned usage period after the required period is less than the planned usage amount is the mobile body (electric vehicle) that can be used in the required period. Exclude from 100 candidates. It should be noted that the determination unit 332 can use the determination unit 332 with ancillary conditions to present to the user even if the mobile body (electric vehicle) 100 has a second usable electric energy less than the planned usage amount in the scheduled usage period after the request period. It may be a candidate for a mobile (electric vehicle) 100 that can be used during the required period. Ancillary condition is that the user acknowledges that the second available electric energy of the mobile body 100 is less than the planned usage amount. It can be said that the user acknowledges that the mobile body 100 is charged by himself / herself. In this case, the usage management system 30 presents a discount on the charge required for using the mobile body 100 as a merit that the user acknowledges that the second available electric energy amount of the mobile body 100 is less than the planned usage amount. Can be done.

In this way, in the present embodiment, the determination unit 332 matches the user's request regarding the electric vehicle 100 with one or more mobile bodies (electric vehicles) 100 that can be used during the request period based on the determination information. Select as electric vehicle 100.

The notification unit 333 of the usage management system 30 transmits notification information for notifying the user of one or more electric vehicles 100 that match the user's request selected by the determination unit 332 to the terminal device 50. As a result, the terminal device 50 presents the information of one or more electric vehicles 100 that match the user's request selected by the determination unit 332 to the user by the input / output unit 51. The user can use the input / output unit 51 to select a desired electric vehicle 100 from one or more electric vehicles 100 presented to the input / output unit 51. The terminal device 50 transmits the information of the electric vehicle 100 selected by the user to the usage management system 30. If there is no electric vehicle 100 that meets the user's request, it may be notified that there is no electric vehicle 100 that meets the user's request.

The update unit 334 of the usage management system 30 receives the information of the electric vehicle 100 selected by the user from the terminal device 50. The update unit 334 notifies the terminal device 50 and the charge management system 20 that the planned use period of the electric vehicle 100 selected by the user is determined. The update unit 334 changes the usage schedule and sets a period corresponding to the requested period as the planned usage period for the electric vehicle 100 selected by the user. In this way, the update unit 334 changes (updates) the usage schedule according to the user's request. Further, the update unit 334 sets the required power amount for the required period as the planned usage amount for the period corresponding to the requested period (newly set scheduled usage period).

The determination unit 233 of the charge management system 20 has a function of determining a charge schedule. Specifically, the determination unit 233 is used to secure a plurality of electric energy consumptions based on the usage schedules of the plurality of electric vehicles 100 based on the chargeable period of each of the plurality of electric vehicles 100 obtained from the usage schedules. The charging schedule of the electric vehicle 100 is determined. Here, as described above, the usage schedule is acquired from the usage management system 30 by the acquisition unit 321. That is, the charge management system 20 acquires the usage schedule from the usage management system 30 by the acquisition unit 321.

The process of determining the charging schedule will be explained in more detail below. When the usage schedule is acquired by the acquisition unit 321, the determination unit 233 extracts each rechargeable period of the plurality of electric vehicles 100 from the usage schedule. The rechargeable period is a period that can be used for charging the storage battery 110 of the electric vehicle 100. In the present embodiment, in each electric vehicle 100, a period that does not overlap with the planned use period is extracted as a rechargeable period. For example, in the case of the usage schedule shown in FIG. 7, for the electric vehicle 100A, the periods of 00:00 to 08:00, 12:00 to 14:00, and 18:00 to 00:00 are the planned usage periods U11 and U12. Since none of them overlap, it is extracted as the rechargeable period. For the electric vehicle 100B, since the period from 00:00 to 08:00, 10:00 to 16:00, and 18:00 to 00:00 does not overlap with any of the planned usage periods U21 and U22, it is extracted as a rechargeable period. Will be done. For the electric vehicle 100C, the period from 00:00 to 08:00, 12:00 to 14:00, and 16:00 to 00:00 does not overlap with any of the planned usage periods U31 and U32, so it is extracted as a rechargeable period. Will be done. The electric vehicle 100D is extracted as a rechargeable period because the periods from 00:00 to 08:00 and 18:00 to 00:00 do not overlap with the planned use period U41.

In determining the charging schedule, the determination unit 233 sets the scheduled charging period in the rechargeable period so that the remaining amount of the storage battery 110 exceeds the planned usage amount in each of the plurality of electric vehicles 100. Here, as described above, the information regarding the planned usage amount is acquired from the usage management system 30 by the acquisition unit 321. That is, the charge management system 20 acquires information on the planned usage amount during the scheduled usage period from the usage management system 30 by the acquisition unit 321. As an example, it is assumed that the planned usage amount of the electric vehicle 100A is 40% in the planned usage period U11 and 40% in the planned usage period U12. It is assumed that the planned usage amount of the electric vehicle 100B in the planned usage period U21 is 20% and the planned usage amount in the planned usage period U22 is 20%. It is assumed that the planned usage amount of the electric vehicle 100C in the planned usage period U31 is 40% and the planned usage amount in the planned usage period U32 is 20%. It is assumed that the planned usage amount of the electric vehicle 100D during the planned usage period U41 is 100%.

The scheduled charging period is the period for charging the storage battery 110 (the period during which the storage battery 110 is scheduled to be charged). The length of the scheduled charging period may vary depending on the planned charging amount of the storage battery 110 and the performance of the charger 41 used for charging the storage battery 110 of the electric vehicle 100. The planned charging amount corresponds to the increase in the remaining amount of the storage battery 110 due to the charging of the electric vehicle 100. The planned usage amount for the scheduled usage period is acquired from the usage management system 30 by the acquisition unit 231. In this embodiment, the planned usage amount is expressed based on the remaining amount (remaining capacity) of the storage battery 110. Further, in the present embodiment, the remaining amount (remaining capacity) of the storage battery 110 is represented by SOC (State of Charge). However, the remaining amount of the storage battery 110 may be represented by an index other than SOC. The remaining amount of the storage battery 110 may be expressed by using a well-known unit as the unit of the remaining amount of the storage battery 110, and for example, watt hour (Wh), amp-hour (Ah) and the like can be used. Further, the remaining amount of the storage battery 110 may be represented by an index corresponding to the remaining amount of the storage battery 110. An example of such an index is a distance (km) that can be moved depending on the remaining amount of the storage battery 110. By expressing the remaining amount of the storage battery 110 by whether it can be moved or by the distance, it becomes easy for the user to grasp how much the electric vehicle 100 can be used.

In the electric vehicle 100A, in order for the remaining amount of the storage battery 110 to be equal to or more than the planned amount to be used during the planned use periods U11 and U12, the remaining amount of the storage battery 110 at 08:00 is 40% or more, and at 14:00. The remaining amount of the storage battery 110 needs to be 40% or more. In the electric vehicle 100B, in order for the remaining amount of the storage battery 110 to be equal to or more than the planned amount to be used during the planned use periods U21 and U22, the remaining amount of the storage battery 110 at 08:00 is 20% or more, and at 16:00. The remaining amount of the storage battery 110 needs to be 20% or more. In the electric vehicle 100C, in order for the remaining amount of the storage battery 110 to be equal to or more than the planned amount to be used during the planned use periods U31 and U32, the remaining amount of the storage battery 110 at 08:00 is 40% or more, and at 14:00. The remaining amount of the storage battery 110 needs to be 20% or more. In the electric vehicle 100D, in order for the remaining amount of the storage battery 110 to be equal to or more than the planned amount to be used in the planned use period U41, the remaining amount of the storage battery 110 at 08:00 must be 100% or more.

The determination unit 233 uses the remaining amount of the storage battery 110 at the reference time of each of the plurality of electric vehicles 100 in determining the planned charge amount. That is, the determination unit 233 determines the charging schedule based on the remaining amount of the storage battery 110 at the reference time of each of the plurality of electric vehicles 100. In the present embodiment, the reference time is the start time of the usage schedule (the start time of the designated period). In the example of FIG. 7, 00:00 on the right side is the start time of the usage schedule and is used as the reference time. As an example, the remaining amount of the storage battery 110 at the reference time of the electric vehicle 100A is 80%, the remaining amount of the storage battery 110 at the reference time of the electric vehicle 100B is 0%, and the remaining amount of the storage battery 110 at the reference time of the electric vehicle 100C is 20%. It is assumed that the remaining amount of the storage battery 110 at the time of reference of the electric vehicle 100D is 40%. The reference time is not limited to the above example, and may be a time when the remaining amount of the storage battery 110 of the electric vehicle 100 can be acquired. That is, at the reference time, the remaining amount of the storage battery 110 is directly detected by using the current sensor 43 or the like, or the remaining amount of the storage battery 110 calculated in the electric vehicle 100 is sent to the charge management system 20 via the communication network 60. It may be the timing when the remaining amount of the actual storage battery 110 can be obtained by sending or the like. Examples of the time when the remaining amount of the storage battery 110 of the electric vehicle 100 can be obtained are the start and end of the use of the electric vehicle 100 before the rechargeable period, and the electric vehicle before the scheduled use period. The start and end of charging 100 can be mentioned. Therefore, the reference time is periodically one of the start and end of the use of the electric vehicle 100 before the rechargeable period and one of the start and end of the charge of the electric vehicle 100 before the scheduled use period. It may be selected from a predetermined time, a predetermined time in a predetermined period, or the like, or it may be set in advance. Here, the predetermined period coincides with the specified period of the usage schedule. That is, the predetermined period is one day. The predetermined time is 08:00.

In the electric vehicle 100A, the remaining amount of the storage battery 110 at 00:00 is 80%, and the planned usage amount of the planned usage period U11 is 40%. Therefore, the battery is not necessarily charged during the rechargeable period from 00:00 to 08:00. There is no need to set a scheduled period. However, since there is a planned use period U12 after the planned use period U11, it is preferable to charge the storage battery 110. As an example, as shown in FIG. 8, it is scheduled to be charged from 00:00 to 02:00 during the rechargeable period from 00:00 to 08:00 so that the remaining amount of the storage battery 110 becomes 100% at 08:00. A scheduled charging period C11 with a volume of 20% can be set. In this case, since the remaining amount of the storage battery 110 at the end of the planned use period U11 (12:00) is 60% and the planned use amount of the planned use period U12 is 40%, it is from 12:00 to 14:00. It is not always necessary to set the scheduled charging period for the rechargeable period. Here, as shown in FIG. 8, a scheduled charging period C12 in which the scheduled charging amount is 20% or more can be set during the rechargeable period from 12:00 to 14:00. In this case, the remaining amount of the storage battery 110 at the end of the scheduled use period U12 (18:00) becomes 40%. During the rechargeable period from 18:00 to 00:00, the planned charge amount will be from 20:00 to 00:00 so that the remaining amount of the storage battery 110 at 00:00 on the next day will be a predetermined value (for example, 80%). A 40% scheduled charging period C13 can be set.

In the electric vehicle 100B, the remaining amount of the storage battery 110 at 00:00 is 0%, and the planned usage period U21 is 20%. Therefore, it is scheduled to be charged during the rechargeable period from 00:00 to 08:00. It is necessary to set a scheduled charging period in which the amount is 20% or more. As an example, as shown in FIG. 8, a scheduled charging period C21 in which the scheduled charging amount is 40% can be set from 00:00 to 04:00. In this case, since the remaining amount of the storage battery 110 at the end of the planned use period U21 (10:00) is 20% and the planned use amount of the planned use period U22 is 20%, it is from 10:00 to 16:00. It is not always necessary to set the scheduled charging period for the rechargeable period. Here, as an example, as shown in FIG. 8, a scheduled charging period C22 in which the scheduled charging amount is 60% or more can be set from 10:00 to 16:00. In this case, the remaining amount of the storage battery 110 at the end of the scheduled use period U22 (18:00) becomes 40%. During the rechargeable period from 18:00 to 00:00, the planned charge amount will be from 18:00 to 20:00 so that the remaining amount of the storage battery 110 at 00:00 on the next day will be a predetermined value (for example, 80%). A 20% scheduled charging period C23 and a scheduled charging amount C24 having a scheduled charging amount of 20% can be set from 22:00 to 00:00.

In the electric vehicle 100C, the remaining amount of the storage battery 110 at 00:00 is 20%, and the planned usage period U31 is 40%. Therefore, it is scheduled to be charged during the rechargeable period from 00:00 to 08:00. It is necessary to set a scheduled charging period in which the amount is 20% or more. As an example, as shown in FIG. 8, a scheduled charging period C31 in which the scheduled charging amount is 60% can be set from 00:00 to 06:00. In this case, since the remaining amount of the storage battery 110 at the end of the planned use period U31 (12:00) is 20% and the planned use amount of the planned use period U32 is 20%, it is from 12:00 to 14:00. It is not always necessary to set the scheduled charging period for the rechargeable period. Here, as an example, as shown in FIG. 8, a scheduled charging period C32 in which the scheduled charging amount is 20% can be set from 12:00 to 14:00. In this case, the remaining amount of the storage battery 110 at the end of the scheduled use period U32 (16:00) becomes 20%. During the rechargeable period from 16:00 to 00:00, the planned charge amount will be from 16:00 to 22:00 so that the remaining amount of the storage battery 110 at 00:00 on the next day will be a predetermined value (for example, 80%). A 60% scheduled charging period C33 can be set.

In the electric vehicle 100D, the remaining amount of the storage battery 110 at 00:00 is 40%, and the planned usage amount of the planned usage period U41 is 100%. Therefore, charging is performed during the rechargeable period from 00:00 to 08:00. It suffices to set a scheduled charging period in which the planned amount is 60%. Here, as shown in FIG. 8, a scheduled charging period C41 in which the scheduled charging amount is 60% can be set from 02:00 to 02:00. In this case, the remaining amount of the storage battery 110 at the end of the scheduled use period U41 (18:00) becomes 0%. During the rechargeable period from 18:00 to 00:00, the planned charge amount will be from 18:00 to 00:00 so that the remaining amount of the storage battery 110 at 00:00 on the next day will be a predetermined value (for example, 60%). A 60% scheduled charging period C42 can be set.

In the present embodiment, the determination unit 233 determines the charging schedule so that the total electric power used for charging the plurality of electric vehicles 100 does not exceed the threshold value. For example, in FIG. 8, from 00:00 to 02:00, the scheduled charging periods C11, C21, and C31 overlap, but the total value of the electric power used for charging the electric vehicles 100A to 100C does not exceed the threshold value. It is adjusted so that. Similarly, from 20:00 to 22:00, the scheduled charging periods C13, C33, and C42 overlap, but the total value of the electric power used for charging the

electric vehicles

100A, 100C, and 100D does not exceed the threshold value. Is adjusted to. In this way, the total power used to charge the plurality of electric vehicles 100 is adjusted so as not to exceed the threshold value throughout the charging schedule.

In the present embodiment, the power supply system 40 can charge a plurality of electric vehicles 100 by using a plurality of power sources including a commercial AC power source 210 and a distributed power source 300. That is, a plurality of power sources can be used to charge the plurality of electric vehicles 100. In this case, the threshold value is set so that the power from a specific power source among the plurality of power sources is equal to or less than a specified value. In this embodiment, the specific power source is a commercial AC power source 210. The specified value may be the upper limit of the electric power that can be used for charging the electric vehicle 100 among the electric power from the commercial AC power source 210. The upper limit can be set, for example, based on the contracted power of the electric utility's electricity rate plan. For example, in the facility 400, an upper limit value of the electric power that can be used for charging the electric vehicle 100 can be set so that the electric power from the commercial AC power source 210 does not exceed the contract electric power. Therefore, by setting the threshold value, it is possible to prevent the electric power from the commercial AC power source 210 from exceeding the contract electric power due to the charging of the plurality of electric vehicles 100. The threshold value and the specified value may be changed depending on the time zone. As an example, the daytime time zone may be set to have a lower threshold value or a specified value than the midnight time zone.

Further, the determination unit 233 may determine the charging schedule so that the electric power is supplied according to the priority of the plurality of electric vehicles 100. That is, the electric vehicle 100 having a high priority may be charged preferentially. Further, the determination unit 233 may determine the charging schedule so that the charging speed is changed according to the priority of the plurality of moving bodies (electric vehicle 100). That is, the electric vehicle 100 having a high priority may be set to have a large charge amount per unit time. For example, the electric vehicle 100 having a high priority may be charged by a charger for quick charging, and the electric vehicle 100 having a low priority may be charged by a charger for normal charging. Here, the priority is based on at least one of the usage mode of each of the plurality of electric vehicles 100, the frequency of use of each of the plurality of electric vehicles 100, and the remaining amount of the storage battery 110 of each of the plurality of electric vehicles 100. Can be set. The usage mode is obtained from the attribute information of the electric vehicle 100. As described above, as the usage mode, it is assumed that the company employee uses it (in-business use) and the non-company employee uses it (non-business use, car sharing and rental car). There is. For example, in the case of use within business, the priority may be set high, and in the case of use outside business, the priority may be set low. The frequency of use may be, for example, the number of times the electric vehicle 100 has been used within a certain period of time. The frequency of use can be determined by the usage management system 30 from the usage history of each electric vehicle 100. For example, the higher the frequency of use, the higher the priority, and the lower the frequency of use, the lower the priority. The remaining amount of the storage battery 110 can be obtained from each electric vehicle 100. For example, the lower the remaining amount of the storage battery 110, the higher the priority, and the larger the remaining amount of the storage battery 110, the lower the priority. The priority of the electric vehicle 100 can be changed as appropriate.

When the update unit 334 notifies that the determination unit 233 of the charge management system 20 confirms the planned usage period of the electric vehicle 100 selected by the user, the usage schedule is changed according to the determination of the scheduled usage period. , Determine the charging schedule. That is, the charging schedule is reset in order to reduce the possibility that the remaining amount of the storage battery 110 of the electric vehicle 100 becomes insufficient when it is required by increasing the new scheduled usage period in the usage schedule.

Along with this, the charging schedule is decided. Here, the determination unit 233 changes the charging schedule so as to compensate for the decrease in the remaining amount of the storage battery 110 of the electric vehicle 100A at the end of the usage schedule. As an example, as shown in FIG. 10, for the electric vehicle 100A, the scheduled charging period C13 from 20:00 to 00:00 is changed to the scheduled charging period C14 from 18:00 to 00:00. Along with this change, the scheduled charging period C23 has been canceled for the electric vehicle 100B. In this example, the electric vehicle 100A has a higher priority than the electric vehicle 100B, and the charging of the electric vehicle 100A is prioritized over the electric vehicle 100B.

For example, FIG. 11 shows an example in which the usage schedule is changed by the update unit 334 for the request period from 12:00 to 14:00 as in FIG. 9. In FIG. 11, the update unit 334 changes the usage schedule and sets the period corresponding to the requested period (12:00 to 14:00) as the scheduled usage period U33 for the electric vehicle 100C selected by the user. Then, when the update unit 334 notifies that the determination unit 233 of the charge management system 20 determines the scheduled use period of the electric vehicle 100C selected by the user, the usage schedule according to the determination of the scheduled use period U33 is set. With the change, the charging schedule will be decided. Here, the determination unit 233 changes the charging schedule so as to compensate for the decrease in the remaining amount of the storage battery 110 of the electric vehicle 100C at the end of the usage schedule. As an example, as shown in FIG. 12, for the electric vehicle 100C, the scheduled charging period C33 is changed from the period of 16:00 to 22:00 to the period of 16:00 to 00:00. Along with this change, the scheduled charging period C24 has been canceled for the electric vehicle 100B. In this example, the electric vehicle 100C has a higher priority than the electric vehicle 100B, and is the result of prioritizing the charging of the electric vehicle 100C over the electric vehicle 100B.

For example, FIG. 13 shows an example in which the usage schedule is changed by the update unit 334 for the request period from 12:00 to 14:00 as in FIGS. 9 and 11. In FIG. 13, the update unit 334 changes the usage schedule and sets the period corresponding to the requested period (12:00 to 14:00) as the scheduled usage period U23 for the electric vehicle 100B selected by the user. Then, when the update unit 334 notifies that the determination unit 233 of the charge management system 20 determines the scheduled use period of the electric vehicle 100B selected by the user, the usage schedule according to the determination of the scheduled use period U23 is set. With the change, the charging schedule will be decided. Here, the determination unit 233 changes the charging schedule so as to compensate for the decrease in the remaining amount of the storage battery 110 of the electric vehicle 100B at the end of the usage schedule. As an example, as shown in FIG. 14, for the electric vehicle 100B, the scheduled charging periods C23 and C24 are changed to the scheduled charging period C25 (18:00 to 00:00) including these. Along with this change, for the electric vehicle 100C, the scheduled charging period C33 is changed to the scheduled charging period C35 (16:00 to 20:00), which is shorter than the scheduled charging period C33. In this example, the electric vehicle 100B has a higher priority than the electric vehicle 100C, and the charging of the electric vehicle 100B is prioritized over the electric vehicle 100C.

The above-described embodiment can be changed in various ways depending on the design and the like as long as the subject of the present disclosure can be achieved. The modifications of the above embodiment are listed below. The modifications described below can be applied in combination as appropriate.

In one modification, the determination unit 233 may redetermine the charging schedule in response to a request from the usage management system 30. For example, when the determination unit 332 determines that there is no electric vehicle 100 that matches the user's request regarding the electric vehicle 100, the determination unit 332 may request the determination unit 233 to redetermine the charging schedule. In this case, the determination unit 233 may determine the charging schedule again from the usage schedule tentatively set with the request period corresponding to the user's request as the scheduled usage period. As a result, if the amount of electric power to be used can be secured during the planned use period included in the use schedule, the determination unit 332 can determine that there is an electric vehicle 100 that meets the user's request regarding the electric vehicle 100.

In one modification, a period for preferentially charging the storage battery 110 of the electric vehicle 100 may be provided during the rechargeable period. In general, electricity charges tend to be cheaper during midnight hours than during daytime hours. Therefore, when the rechargeable period includes the midnight time zone and the daytime time zone, the amount of electric power used for charging the storage battery 110 of the electric vehicle 100 is larger than that in the daytime time zone in the midnight time zone. Good. For example, the determination unit 233 may set the scheduled charging amount in the scheduled charging period belonging to the midnight time zone to be larger than the scheduled charging amount in the scheduled charging period belonging to the daytime time zone.

In one modification, the determination unit 233 may determine the charge amount of the storage battery 110 of the plurality of electric vehicles 100 based on the attribute information of each of the plurality of electric vehicles 100. As an example, the charge amount may be the upper limit value of the remaining amount of the storage battery 110 of the electric vehicle 100 during the rechargeable period. For example, the attribute information may include at least one of the type, use, initial position, destination, planned distance traveled, number of people traveled, and mode of use, as described above. Examples of these attribute information are as described above. For example, when it is determined that the electric cost of the electric vehicle 100 is relatively good from the types included in the attribute information, the determination unit 233 may set the charge amount to be small. Further, when it is determined that the required electric power amount of the electric vehicle 100 is relatively small from the usage, the initial position, the destination, the planned travel distance, etc. included in the attribute information, the determination unit 233 sets the charge amount to be small. You can do it. Further, when the number of people scheduled to move included in the attribute information is large, the determination unit 233 may set a large amount of charge.

The charging location may be determined by the determination unit 233 based on the charging schedule. For example, in the power supply system 40, when a plurality of chargers 41 include a charger 41 (41A) capable of quick charging, when determining a charging schedule, a specific electric vehicle 100 is rapidly charged by the charger 41A. The scheduled charging period can be set so that charging takes place. In this case, the specific electric vehicle 100 is required to be arranged in a place where it can be charged by the charger 41A at the start of the scheduled charging period. In this case, the notification unit 235 notifies the usage management system 30 of the charging location where the moving body (electric vehicle 100) is arranged at the end of the scheduled usage period included in the usage schedule. Then, the usage management system 30 may send guidance information for arranging the electric vehicle 100 at the charging place to the terminal device 50. This makes it possible to encourage the user to place the electric vehicle 100 at the charging location at the end of the planned use period. Further, the charging location may be determined so that the electric vehicle 100 is charged only by a specific power source among the plurality of power sources. The particular power source may be, for example, a distributed power source 300 that utilizes only renewable energy. For example, in the power supply system 40, when a plurality of chargers 41 include a specific charger 41 that can be charged only by power from a distributed power source 300 that utilizes renewable energy, when determining a charging schedule, The charging location may be set so that the specific electric vehicle 100 is charged by the specific charger 41. Since the electric vehicle 100 charged only with renewable energy has an advantage in calculating the carbon dioxide emission amount, it is possible to increase the value of the electric vehicle 100.

In one modification, the determination unit 233 notifies that the charging schedule cannot be set when the charging schedule that can secure the amount of power used based on the usage schedules of the plurality of mobile bodies (electric vehicles) 100 cannot be set. The usage management system 30 may be notified from the unit 235. As a result, the usage management system 30 can review the usage schedule.
