Display determination unit 413 and price determination unit 415 output the determined display mode and battery price of battery 200 to writing unit 417.

When the battery ID read by the reading unit 401 is input, the deterioration degree calculating unit 411 extracts the accumulated usage history information stored in the history storage unit 427 by the battery ID, and extracts the accumulated usage history information. Based on this, a degree of deterioration indicating the degree of deterioration of the battery 200 is calculated and output. Note that calculating the degree of deterioration of the battery 200 based on the accumulated usage history information includes calculating the degree of deterioration based on the accumulated operation history information, and calculating the degree of deterioration based on the accumulated usage history information.

The management device 400 further includes a lending processing unit 407 that performs lending processing on a specific battery 200 stocked in the station 300. When the lending processing unit 407 determines that the battery 200 can be lent, the lending processing unit 407 outputs an instruction to rent the battery 200 to the station 300.

In this case, when the vehicle ID read by the reading unit 401 matches the vehicle ID included in the vehicle ID list stored in the ID list storage unit 429, the lending processing unit 407 stores the stock ID in the station 300. It is determined that the used battery 200 may be lent. In addition to or instead of this, the lending processing unit 407 matches the user ID read by the reading unit 401 with the user ID included in the user ID list stored in the ID list storage unit 429. In such a case, it may be determined that the battery 200 may be lent out. Further, instead of or in addition to this, the lending processing unit 407 includes a battery ID that is included in the battery ID list in which the battery ID read by the reading unit 401 is stored in the ID list storage unit 429. May be determined to be lent out.

The lending processing unit 407 lends the battery 200 that is normally charged. However, when the prediction unit 503 of the server 500 predicts the excess or deficiency of the battery 200 at the station 300, the battery 200 having a charge amount corresponding thereto may be lent out.

FIG. 9 is a block diagram of the server 500. The server 500 includes a communication unit 501 that communicates with the power company terminal 32, the communication terminal 70, the management device 400, and the environment information distribution device 50, and a battery stocked in the station 300 based on information input from the communication unit 501. A prediction unit 503 that predicts 200 excesses and deficiencies. The communication unit 501 is an example of a reception unit and an environment acquisition unit.

The server 500 further transmits a recommendation information that recommends replacing the battery 200 at the specific station 300 from the communication unit 501 to the communication terminal 70 in order to eliminate the excess or deficiency predicted by the prediction unit 503. 505 and reward information for giving a reward to the user 60 who replaced the battery 200 at the specific station 300 in accordance with the recommendation by the recommendation unit 505 from the communication unit 501 to the communication terminal 70 of the user 60 And a reward section 507.

The server 500 further includes a storage unit 510 including a reward information storage unit 511, a management device information storage unit 513, and a cumulative usage history information storage unit 515. The reward information storage unit 511 stores reward information, and the management device information storage unit 513 stores information related to a plurality of management devices 400, such as the IP address and address information of each management device 400. The accumulated usage history information storage unit 515 stores accumulated usage history information. The accumulated usage history information includes information obtained by associating the usage history information with the user ID.

When the communication unit 501 receives the power saving notice information of each area from the power company terminal 32, the communication unit 501 outputs the information to the prediction unit 503. The communication unit 501 also outputs the usage history information and the user ID read from the battery 200 used in the vehicle 100 by the management device 400 to the reward unit 507 and the prediction unit 503 when received from the management device 400. In addition, when the communication unit 501 receives environment information of each area from the environment information distribution device 50, the communication unit 501 outputs the information to the prediction unit 503.

When the prediction unit 503 receives the power saving notice information from the communication unit 501, the power that can be accommodated from each station 300 to the power transformation device 35 in the time zone where a power saving request is expected in each area indicated in the power saving notice information, Prediction is made based on environmental information and usage history information of each area input from the communication unit 501. The prediction unit 503 further determines whether the predicted power that can be used is greater or less than the amount of power that is predetermined for the shortage of power in the time period indicated in the power saving notice information. To do. Thereby, the prediction unit 503 predicts whether the battery 200 is excessive or insufficient at each station 300.

When the prediction result of the excess or deficiency of the battery 200 is input from the prediction unit 503, the recommendation unit 505 stores the user stored in the accumulated usage history information storage unit 515 in order to eliminate the excess or deficiency of the battery 200 of each station 300. The recommended information is transmitted to the communication terminal 70 of the user 60 corresponding to the ID to prompt the user 60 to perform a specific action.

For example, the recommended information is determined in advance from the above-mentioned time zone at the station 300 where the shortage of the battery 200 is predicted in order to secure the above-mentioned predetermined accommodation power amount in the time zone in which the power saving request is expected. The battery 200 should be replaced by a predetermined amount of time before, for example, two hours before. " Instead of or in addition to this, the recommended information is that "the battery 200 is not replaced in the time zone including two hours before and after the above time zone at the station 300 where the shortage of the battery 200 is predicted", "Return the charged battery 200 by the above-mentioned time zone at the station 300 where the shortage of the battery 200 is predicted", "Not the station 300 where the battery 200 is predicted to be insufficient but the station 300 where the battery 200 is predicted to be excessive “Replace the battery 200”.

When the usage history information and the user ID are input from the communication unit 501, the reward unit 507 refers to the cumulative usage history information storage unit 515, the user ID of the user 60 to whom the recommendation unit 505 has transmitted the recommended information, and the communication unit It is determined whether or not the user ID input from 501 matches. If they match, the reward information storage unit 511 is referred to, and the reward information is transmitted from the communication unit 501 to the communication terminal 70 corresponding to the matched user ID.

The prediction method by the prediction unit 503 of the server 500 will be further described using a specific example. The said prediction method is set based on the past performance or simulation, or by learning of AI. The prediction method is recorded in the prediction unit 503 as a mathematical formula, a part of software, or the like.

In the prediction method, for example, in each of the environmental information and the usage history information, the case is divided into a case where the number of batteries 200 exchanged in the corresponding station 300 is increased and a case where the number is decreased. In that case, it estimates using the ratio in each case of the number of the batteries 200 replaced | exchanged.

For example, when weather information, which is an example of environmental information, indicates that rain, snow, sleet, leopard, etc. falls in a specific area, the prediction method is compared with the case of sunny, cloudy, etc. The number of batteries 200 exchanged at the station 300 is predicted to be smaller by a certain percentage. In the case where the vehicle 100 is a four-wheeled vehicle, when it is shown that it will rain, the number of batteries 200 to be replaced may be predicted more than when it is sunny.

Also, when the traffic jam information indicates that there is a traffic jam on a road included in a specific area, the prediction method predicts a small number of batteries 200 to be exchanged at the station 300 in the area. In addition, when the construction information indicates that the road is closed on a road in a specific area, the prediction method predicts a small number of batteries 200 to be exchanged at the station 300 in the area. On the other hand, the number of batteries 200 exchanged at the station 300 in the area including the detour on the closed road is predicted to be large.

Furthermore, using the prediction method, the remaining charge of the battery 200 returned to the station 300 in a specific time zone is predicted based on, for example, a charge amount and a discharge amount which are an example of usage history information. Further, based on the remaining charge amount and the deterioration grade that is another example of the usage history information, the amount of power that can be accommodated from the battery 200 accommodated in the station 300 to the power system in a specific time zone is predicted. To do.

In this case, the higher the deterioration grade, that is, the lower the deterioration, the lower the power that can be accommodated, thereby extending the life of the battery. For example, 6 kW for a

new degradation grade

1, 5 kW for degradation grade 2, 4 kW for

degradation grade

3, 3 kW for degradation grade 4, 2 kW for degradation grade 5, and so on.

For the sake of further explanation of the specific example, the following situation is assumed in FIG. In areas A and B, stations A and B with the same number of batteries are installed. In addition, the power saving request notice information in each area is expected to have a power shortage of 3000 kW between 14:00 and 16:00 in area A, and a power shortage of 1000 kW between 8 and 9 in the area B and between 17:00 and 18:00. Is shown.

Further, in both the station A and the station B, it is predetermined that 1% of the shortage of power in each time zone is interchanged, that is, the station A interchanges 30 kW between 14:00 and 16:00, and the station B It is stipulated that 10 kW of power will be accommodated between 8 o'clock and 9 o'clock and 17 o'clock to 18 o'clock.

In the above situation, according to the weather information, it is assumed that it will be cloudy all day tomorrow in Area A, but it will snow in Area B in the morning. Further, according to the use history information, tomorrow is a weekday and all batteries are being rented out from 14:00 to 16:00 in station A, and 4 batteries in station B from 8:00 to 9:00 and from 17:00 to 18:00. Suppose that there is a history of remaining.

Based on the weather information, for example, the prediction unit 503 determines that the battery lending amount is normal at the station A in the area A, but is smaller than normal at the station B in the area B, for example, about 80% of the normal battery lending amount. Predict. Further, the prediction unit 503 also refers to the use history information, and tomorrow, all the batteries are rented out from 14:00 to 16:00 in the station A, and the battery is 5 in the station B from 8:00 to 9:00 and from 17:00 to 18:00. Predict that it will remain.

Furthermore, the prediction unit 503 predicts that the power that can be accommodated between 14:00 and 16:00 is 0 kW because the station A has zero batteries. On the other hand, the prediction unit 503 uses the remaining charge amount and the deterioration grade included in the usage history information of the five batteries remaining between 8 o'clock and 9 o'clock and 17:00 to 18:00 in the station B to provide 15 kW of available power. Predict. The prediction unit 503 further compares the power required for accommodation with the power that can be accommodated, and station A has a shortage of 30 kW between 14:00 and 16:00, and station B has 8 to 9 and 17 to 18 Predicting over 5 kW over time.

As illustrated above, the excess or deficiency of the battery 200 predicted by the prediction unit 503 indicates the number of batteries 200 accommodated in the station 300, the amount of power that can be accommodated in the power system from the plurality of batteries 200 accommodated in the station 300, and the power Includes the amount of power that can be stored from the grid.

Based on the above prediction result, the recommendation unit 505 refers to the use history information. For example, there is a history that the vehicle 100 is not used during the weekday and the history of borrowing the battery 200 of the degradation class 1 at the station A. A plurality of, for example, five users 60 are extracted. Further, the recommendation unit 505 transmits recommended information that recommends returning the battery 200 to the station A by 12:00 to the communication terminal 70 of the user 60.

Instead, the recommendation unit 505 refers to the usage history information, and extracts, for example, six users 60 who have a history of coming to the station A in the morning on weekdays to borrow a battery 200 that has been charged with a degradation class 2. If you plan to borrow the battery 200 from the station A tomorrow as usual, we recommend that you borrow the battery 200 with a high degradation grade, or recommend information that recommends "borrowing to the station B" You may send it. In this case, the recommendation unit 505 may transmit the latter recommended information to the communication terminal 70 of the user 60 who has a history of using the station B with reference to the usage history information.

The recommendation unit 505 may include a recommendation rank according to the extent that the excess or deficiency of the battery 200 can be eliminated in the recommendation information. An example of such recommended information is: “If you have enough battery charge in your car and have time tomorrow, please return the battery to station A by 14:00 tomorrow. Reward rank is S. ”“ If you plan to borrow a charged battery at station A between 12:00 and 18:00 tomorrow, please go to station B instead of station A. The reward rank is A. "" If you plan to borrow a charged battery at station A by 14:00 tomorrow, please borrow a battery with a degradation grade of 5 or higher. B. " The reward rank is reflected, for example, on the extent of discounting the battery rental fee, giving points that can be used to pay the battery rental fee, and giving a product voucher at a partner store. In addition, the user 60 may be able to confirm the deterioration grade of the battery 200 that is currently rented by using the deterioration display unit 240 of the battery 200, for example.

FIG. 10 is a flowchart according to the first embodiment. When the battery 200 is attached to the vehicle 100, the vehicle 100 writes the use history information and the user ID in the battery 200 in advance (step S101). When the battery 200 is returned to the station 300, the management apparatus 400 reads the use history information and the user ID written in the battery 200 via the station 300 (step S103).

The management device 400 transmits the read usage history information and user ID to the server 500 (step S105), and the server 500 stores the received usage history information and user ID in association with each other (step S107). By repeating steps S101 to S107, the server 500 accumulates usage history information together with the user ID.

When the server 500 receives the power saving request notice information in the area including the station 300 from the power company terminal 32 (step S109), the server 500 acquires the environment information distributed to the communication network 40 by the environment information distribution device 50 (step S109). S111), based on the usage history information stored cumulatively and the environmental information, the excess or shortage of the battery 200 stocked in the station 300 in the time zone indicated in the power saving request notice information is predicted (step S111). S113).

The server 500 transmits the recommended information to the communication terminal 70 of the specific user 60 based on the excess / deficiency prediction result (step S115). The user 60 who has recognized the recommended information via the communication terminal 70 can connect the battery 200 to the station 300 or another station 300 during or before or after the time period according to the recommendation indicated by the recommended information. To return. Also in this case, as in steps S101 to S105, when the user 100 is mounted on the vehicle 100, the vehicle 100 writes the use history information and the user ID into the battery 200 (step S117). When the battery 200 is returned to the station 300, the management apparatus 400 reads the use history information and user ID written in the battery 200 via the station 300 (step S119), and reads the read use history information and user. The ID is transmitted to the server 500 (step S121).

The server 500 stores the received usage history information and the user ID, and whether or not the user ID matches the user ID of the user 60 who transmitted the recommended information, in other words, by the user 60 who transmitted the recommended information. It is determined whether or not the battery is returned (step S123). When the battery is returned by the user 60 who sent the recommended information (step S123: YES), the reward information is transmitted to the communication terminal 70 of the user 60 (step S125), and the battery is not returned by the user 60 who sent the recommended information. In the case (step S123: NO), the reward information is not transmitted to the communication terminal 70 of the user 60.

When the power transformation device 35 determines that its own area is in a power shortage state, the power transformation device 35 transmits power saving request information to the management device 400 (step S127). Upon receiving the power saving request information from the power transformation device 35, the management device 400 discharges the charged battery 200 stocked in the station 300, thereby allowing power to be passed to the power transformation device 35 (step S129).

If the power transformation device 35 determines that the power interchange has been received from the station 300 in response to the distribution of the power saving request information, it provides the server 500 with a reward corresponding to the amount of interchanged power (step S131). As described above, the flow of FIG. 10 is repeatedly executed while each device such as the server 500 is operating.

In steps S101 to S107, the user ID is transmitted / received together with the usage history information, but the user ID may not be transmitted / received instead. In this case, in step S113, the server 500 statistically predicts whether the battery 200 is excessive or insufficient.

In the above embodiment, when the prediction unit 503 predicts the excess or deficiency of the number of the batteries 200 in the station 300, instead of sending the recommended information, the excess or deficiency is solved for the terminal of the management company of the management system 20. An instruction may be sent. For example, an instruction to transport at least one empty battery 200 from the station 300 in the area A to the station 300 in the area B by 9:00 today may be transmitted from the communication unit 501 to the terminal of the management company. Similarly, the predicting unit 503 prepares at least two batteries 200 charged by 14:00 today so that at least two extra batteries 200 charged by 14:00 today can be prepared at the station 300 in area A. In addition, an instruction for conveying from the station 300 in the area B to the station 300 in the area A may be transmitted from the communication unit 501 to the terminal of the management company. An instruction to transport at least two batteries 200 that are not sufficiently charged from the station 300 in the area B to the station 300 in the area A may be transmitted from the communication unit 501 to the terminal of the management company.

In the above embodiment, the server 500 receives the power saving request notice information from the power company terminal 32. Instead, the server 500 itself calculates the power supply / demand balance of the power system and generates the power saving request notice information. Also good. In this case, the server 500 may calculate the supply and demand balance of the power system using environment information and usage history information in the plurality of stations 300.

Further, in this case, instead of or in addition to the power saving request notice information, the server 500 predicts a time zone in which the power system is oversupplied and charges the battery 200 with the excess supply. The excess or deficiency of the battery 200 may be predicted. The prediction is more effective when a power generation device that generates power using renewable energy such as sunlight is incorporated in the power system.

In the above embodiment, the prediction unit 503 predicts the excess or deficiency of the battery 200 in the time zone indicated in the power saving request notice information. Instead, the prediction unit 503 predicts the excess or deficiency of the battery 200 in any time zone. Also good.

In the above-described embodiment, when the predicting unit 503 determines that the power available for the specific station 300 is less than the predetermined amount of power, the recommendation unit 505 performs the action of the user 60. Prompts. Instead of this or in addition to this, the prediction unit 503 may output an instruction to the management apparatus 400. For example, in order to secure as much as possible of a predetermined proportion of interchangeable power as much as possible, the rental of the battery 200 at the station 300 is suspended from before the above time period until at least the time period ends. An instruction to restrict or raise the rental fee may be transmitted from the communication unit 501 to the management device 400 that controls the station 300 with reference to the management device information storage unit 513. For example, when the prediction unit 503 determines that the power available for the specific station 300 is greater than the amount of the predetermined amount of power, for example, the prediction unit 503 from the station 300 to the transformer 35 in the time period described above. In addition, an instruction to accommodate surplus power may be transmitted from the communication unit 501 to the specific management device 400 with reference to the management device information storage unit 513.

In the above embodiment, the SOC calculation unit 105 updates the SOC-OCV curve read from the battery 200, and based on the updated SOC-OCV curve and the current voltage of the battery 200 input from the charge / discharge amount measurement unit 103. Thus, the current SOC of the battery 200 is calculated. Instead, the SOC calculation unit 105 reads the nominal capacity of the battery 200 measured under a specific condition from the battery 200, and the battery under the same specific condition. The current discharge capacity of 200 may be measured, and the SOC may be calculated as the ratio of the current discharge capacity to the nominal capacity. Alternatively, the SOC calculation unit 105 reads the SOC-OCV curve of the battery 200 measured in advance under a specific condition from the battery 200, measures the current voltage of the battery 200 under the same specific condition, and determines the SOC. The SOC may be measured roughly by comparing it with the OCV curve.

As described above, according to the present embodiment, the server 500 predicts the excess or deficiency of the battery 200 at each station 300 based on the environmental information of each station 300 and the usage history information of the battery 200. Can be used. In particular, since power is interchanged between each station 300 and the power system based on the excess or deficiency, each station 300 can function as a VPP in the power network 10.

In particular, since the battery 200 is an exchangeable mobile battery at the station 300, the battery 100 can be moved from the station 300 when the battery 200 is replaced without causing the station 100 to wait for the station 300 when power is exchanged. Therefore, further utilization of the battery 200 can be promoted. Further, when the vehicle 100 is a motorcycle, the motorcycle is smaller than other vehicles and the size of the battery 200 necessary for driving is small, so that the user 200 can easily replace the battery 200. Therefore, it is possible to prompt the user 60 to replace the battery 200 at the station 300, and the management system 20 of this embodiment is suitable.

FIG. 11 is a schematic diagram of the power network 12 according to the second embodiment, and FIG. 12 is a flowchart according to the second embodiment. The power network 12 predicts the excess or deficiency due to the replacement of the battery 200 at each station 300, and allows the batteries 200 to be interchanged between the plurality of stations 300.

11 and 12, the same components as those in FIGS. 1 to 10 are denoted by the same reference numerals and description thereof is omitted. Further, unless otherwise specified, the area A and the area B perform the same operation, so only the operation in the area A is described and the description in the area B is omitted. Furthermore, steps S201 to S207 in FIG. 12 are the same as steps S101 to S107 in FIG. In the present embodiment, the server 500 cumulatively stores usage history information together with the user ID for each management device A and station A and each management device B and station B in area A and area B.

For example, when a predetermined time such as midnight every day elapses, the server 500 acquires the environmental information distributed to the communication network 40 by the environmental information distribution device 50 (step S211) and stores it cumulatively. Based on the usage history information and the environmental information, the excess or shortage of the battery 200 stocked in the station A and the surplus or shortage of the battery 200 stocked in the station B in an arbitrary time zone of the day. Prediction is made (step S213).

The server 500 transmits recommended information to the communication terminal 70 of the specific user 60 based on the prediction result of excess or deficiency (step S215). The recommended information is, for example, a content that prompts replacement at a station 300 that has more than the station 300 that runs out of battery 200. Specifically, "If you plan to borrow a charged battery at station B between 12:00 and 18:00 today, please go to station A instead of station B. Award rank is A . "Is included.

When the user 60 returns the battery 200 in accordance with the recommendation indicated in the recommendation information, the usage history information and the battery 200 attached to the vehicle 100 of the user 60 are transmitted from the vehicle 100 to the user 200 as in steps S201 to S205. The user ID is written (step S217).
