FIG. 1 briefly shows how the exchange battery system 10 is used. The battery exchange system 10 manages the battery 100. The battery 100 is a battery purchased by the owner 80. The exchange battery system 10 provides countermeasures to the owner 80 of the battery 100 whenever a profit is generated from the charging and/or discharging of the battery 100.

The battery exchange system 10 includes a management server 20, a battery station 30 and an electric motorcycle 40. The management server 20 is an example of a management system. The management server 20 can communicate with the battery station 30 through the communication network 190. The communication network 190 may include a transmission line for wired communication or wireless communication. The communication network 190 may include a communication network including the Internet, a P2P network, a dedicated line, a VPN, a wire communication line, a portable telephone line, and the like. The blockchain network 180 is constructed on the communication network 190. The blockchain network 180 may be a public blockchain/network. The blockchain network 180 may be a private blockchain/network.

The battery 100 is mounted on the electric motorcycle 40. The battery 100 is an exchange battery that can be attached to and detached from the electric motorcycle 40. The battery 100 is used to drive the power source of the electric motorcycle 40 That is, the power source of the electric motor. The battery 100 is a secondary battery such as a lithium ion battery, a nickel hydrogen battery, and a lead storage battery. The electric motorcycle 40 is an example of a vehicle. Vehicles are an example of conveying equipment. In addition, the electric motorcycle 40 may be a hybrid type motorcycle equipped with an internal combustion engine and an electric motor as power sources.

The battery station 30 holds a plurality of batteries. The battery station 30 receives the battery 100 used by the electric motorcycle 40 and provides the other battery 100 charged by the battery station 30 to the user 70 of the electric motorcycle 40. After charging the battery 100 used in the electric motorcycle 40, the battery station 30 provides the charged battery 100 to the user of the electric motorcycle 40 or other electric motorcycles.

The battery station 30 is installed in various facilities, for example. For example, the battery station 30 is installed in facilities such as a post office, a convenience store, a shopping mall, and a parking lot. The battery station 30 uses the electric power supplied from the electric power provider 150 through the grid 160 to charge the battery 100. The electric power provider 150 is an electric power operator including an electric power wholesaler of an electric power company, an operator of a facility where the battery station 30 is installed, and the like.

The battery station 30 lends the battery 100 held by it to the user 70 of the electric motorcycle 40. Specifically, the user 70 of the electric motorcycle 40 takes out the battery 100 from the battery station 30 and installs it on the electric motorcycle 40. The electric motorcycle 40 consumes the electric power stored in the battery 100 to run. When the battery 100 used in the electric motorcycle 40 is exchanged, the user 70 returns the battery 100 used in the electric motorcycle 40 to the battery station 30 and takes out other charged batteries from the battery station 30 instead. The management server 20 calculates the amount of power supplied from the battery 100 during the period in which the battery 100 is lent to the user 70 based on the remaining amount of the returned battery 100 (it may be described as "power provided to the user 70"). Management server The device 20 charges the user 70 an amount corresponding to the amount of power provided to the user 70 as a battery usage fee.

The battery station 30 fully charges the returned battery 100. The management server 20 calculates the profit generated by charging and discharging one set of the battery 100 based on the difference between the battery usage fee levied on the user 70 and the electricity fee required to fully charge the battery 100. In addition, one set of charging and discharging refers to discharging and charging with substantially the same amount of electricity. For example, it indicates discharge performed in a state where the remaining battery level is at a specific value and charging performed until the remaining battery level returns to the specific value. "Charging and discharging" does not limit the order of discharging and charging, and either charging or discharging may be performed first.

The management server 20 records transaction information indicating the amount of power provided to the user 70, the battery usage fee as a price for providing the power to the user 70, and the revenue generated by one set of charging and discharging. For example, the management server 20 records transaction information in the database managed by the management server 20 and the blockchain network 180. In addition, the management server 20 distributes a part of the profit generated by charging and discharging one set of the battery 100 to the owner 80 of the battery 100. The management server 20 notifies the owner terminal 82 of the owner 80 of information indicating the profit distributed to the owner 80.

The management server 20 considers the past profit generated by the charging and discharging of the battery 100 and the remaining life of the battery 100, and provides the owner 80 with information indicating the expected value of the profit generated by the battery 100 in the future. Since the market value of the battery fluctuates according to the energy situation and the like, there is a possibility that the owner 80 can obtain further profit by selling the battery 100 in addition to the profit from the use of the battery 100. According to the management server 20, since the expected value of the profit generated by the battery 100 in the future can be provided to the owner 80, The owner 80 can judge how much final profit can be obtained by selling the battery 100.

Thus, according to the battery exchange system 10, the profit generated from the use of the battery 100 can be appropriately evaluated, and the profit can be appropriately distributed to the owner 80. In addition, the remaining life of the battery 100 can be considered based on the transaction information of the battery 100, so that the future value of the battery 100 can be appropriately evaluated.

In addition, for ease of description, only one battery station 30 is shown in FIG. 1. However, the battery exchange system 10 may include a plurality of battery stations, and the user 70 may return the battery 100 to a battery station different from the battery station where the battery 100 was lent.

In the management server 20, the recording unit 250 generates and records battery usage information including usage event information received from the battery station 30.

After the battery 100 is used by the electric motorcycle 40, if the battery 100 is returned to the battery station 30, the battery station 30 will include the battery ID read from the returned battery 100, the station ID of the battery station 30, and read from the returned battery 100 The SOC of, the "return" as the content of use, and the use event information of the user ID of the user 70 are sent to the management server 20.

In the management server 20, the value determination unit 210 reads the SOC when the battery 100 is lent out from the storage unit 290, and calculates the battery loaned out to the user 70 based on the difference between the remaining battery level and the SOC when the battery is returned to the battery station 30 The amount of electricity provided to the user 70 during the 100 loan period. The value determination unit 210 determines the battery usage fee to be levied on the user 70 based on the power consumption. For example, the value determining unit 210 multiplies the variable unit price by the power consumption to calculate the battery usage fee. The recording unit 250 generates and records battery usage information including usage event information received from the battery station 30 and cost information indicating a battery usage fee.

When the battery station 30 generates surplus power in the grid 160, the battery 100 is charged to restore the SOC of the battery 100 to the SOC when the battery 100 was lent. Examples of surplus power include power during the day when it is fine during the day and the power generated during the surplus time period supplied by solar power generation, midnight power, and the like. The battery station 30 sends the battery ID of the battery 100, the station ID of the battery station 30, the SOC of the battery 100, "3kWh charge" as the content of use, and the usage event information of the "electric company" as the purchaser to the management server器20 sends.

In the management server 20, the recording unit 250 generates and records the battery usage information including the usage event information received from the battery station 30 and cost information indicating the electricity charges related to the charging of the battery 100. In addition, the electricity rate is calculated based on the unit price of electricity and the charge amount of electricity in the time zone during which the battery 100 is charged.

The value determination unit 210 calculates the profit due to the loan of the battery 100 based on the battery usage fee and the electricity fee. As described above, in the case where the battery usage fee is 72 yen and the electricity purchase fee is 24 yen, the value determining unit 210 sets the profit generated by the loan of the battery 100 to 48 yen. The consideration determination unit 220 multiplies the profit of 48 yen by the distribution coefficient 0.5, thereby setting the consideration given to the owner 80 of the battery 100 to 24 yen. The consideration providing unit 230 increases the balance of the transaction account of the owner 80 based on the consideration determined by the consideration determining unit 220. In addition, the consideration notification unit 240 notifies the owner 80 of the consideration determined by the consideration determination unit 220. For example, the counter price notification unit 240 notifies the owner terminal 82 of the owner 80 of the counter price determined by the counter price determination unit 220.

The recording unit 250 records transaction information including the user ID, station ID, power, usage fee, charging fee, revenue, consideration, and date when the charging ends of the user 70. For example, the recording unit 250 records transaction information in the storage unit 290 or the blockchain network 180.

Next, when a power shortage occurs in the power grid 160, the battery station 30 discharges the battery 100 to thereby discharge power to the power grid 160. The battery station 30 manages the usage event information including the battery ID of the battery 100, the station ID of the battery station 30, the SOC of the battery 100, "1kWh selling electricity" as the content of use, and the usage event information of the "electric company" as the seller of electricity. The server 20 sends.

In the management server 20, the recording unit 250 records the The received usage event information and battery usage information indicating the price information for selling electricity. In addition, the electricity selling fee is calculated based on the unit price of electricity purchased by the electricity provider 150 in the time zone during which the electricity was sold and the amount of electricity discharged from the battery station 30 to the grid 160.

When the battery station 30 generates surplus power in the power grid 160, it uses the power supplied from the power grid 160 to charge the battery 100 until it is fully charged. The battery station 30 manages the usage event information including the battery ID of the battery 100, the station ID of the battery station 30, the SOC of the battery 100, the "1kWh purchase of electricity" as the content of use, and the usage event information of the "electric company" as the purchaser of the electricity. The server 20 sends.

In the management server 20, the recording unit 250 records battery usage information including usage event information received from the battery station 30 and cost information indicating the cost of electricity purchase. In addition, the electricity purchase fee is calculated based on the unit price of electricity and the charge amount of electricity in the time zone during which the electricity purchase was performed.

The value determination unit 210 calculates the profit generated from the electricity trading based on the electricity selling fee and the electricity buying fee. For example, as described above, when the electricity selling fee is 28 yen and the electricity buying fee is 8 yen, the value determining unit 210 sets the income generated by the electricity trading to 20 yen. The consideration determination unit 220 multiplies 20 yen by the distribution coefficient 0.5, thereby setting the consideration given to the owner 80 of the battery 100 to 10 yen. The consideration providing unit 230 increases the balance of the transaction account of the owner 80 based on the consideration determined by the consideration determining unit 220. In addition, the consideration notification unit 240 notifies the owner 80 of the consideration determined by the consideration determination unit 220. For example, the counter price notification unit 240 notifies the owner terminal 82 of the owner 80 of the counter price determined by the counter price determination unit 220.

The recording unit 250 records transaction information including the user ID of the user 70, the station ID, the amount of electricity, the electricity selling fee, the electricity buying fee, the income, the consideration, and the date when the charging ends. example For example, the recording unit 250 records transaction information in the storage unit 290 or the blockchain network 180. In this way, every time a set of charging and discharging is performed, the profit due to the charging and discharging is determined and the owner 80 is given a consideration.

FIG. 7 is a flowchart showing the processing executed by the management server 20. The processing of this flowchart starts when the usage event information from the battery station 30 is received.

In S702, the recording unit 250 generates the battery usage information shown in FIG. 4 based on the usage event information received from the battery station 30 and stores it in the storage unit 290. In S704, the value determination unit 210 determines whether one set of charging and discharging is completed. If one set of charging and discharging has not ended, the processing is ended. When one set of charging and discharging ends, in S706, the value determining unit 210 calculates the profit due to the charging and discharging, and the consideration determining unit 220 calculates the consideration to be given to the owner 80 based on the calculated profit.

Next, in S708, the consideration providing unit 230 provides the owner 80 with consideration. In S710, the consideration notification unit 240 notifies the owner terminal 82 of the owner 80 of the consideration paid to the owner 80. In S712, the recording unit 250 records the transaction information. For example, the recording unit 250 stores the transaction information in the storage unit 290. In addition, the recording unit 250 sends the transaction information to the blockchain network 180, thereby recording the transaction information on the blockchain network 180.

In addition, together with the processing of S710 shown in FIG. 7 or independently of the processing of S710 shown in FIG. 7, the value notification unit 260 may notify the owner 80 of information indicating the value generated by the battery 100. The value notification unit 260 may notify the owner 80 of information indicating the value generated by the battery 100 on a regular basis and/or according to a request from the owner 80.

For example, the value notification unit 260 may calculate the value generated by the battery 100 based on the battery usage information and/or transaction information shown in FIG. 4. For example, in the example shown in FIG. 4, the battery 100 supplies electric power to the electric motorcycle 40 by discharging the electric power equivalent to 75% in SOC conversion, and then performs the electric power equivalent to 75% in SOC conversion. The charging of the company generates a profit of 48 yen, and a consideration of 24 yen is given to the owner 80. In addition, the battery 100 discharges power to the grid 160 by discharging the power equivalent to 25% in SOC conversion, and then charges the power equivalent to 25% in SOC conversion to generate a profit of 20 yen, and A consideration of 10 yen is given to the owner 80. Therefore, through one cycle of charging and discharging, a profit of 68 yen is generated, and a consideration of 34 yen is given to the owner 80.

Here, it is assumed that a profit of 34 yen is generated for each cycle performed. If 300 cycles of charging and discharging have been performed so far, a consideration of 10,200 yen will be given to the owner 80 so far. Assume that owner 80 invests 55,000 yen to purchase battery 100. In addition, it is assumed that the battery life of the battery 100 is 1000 cycles. At this time, since the battery 100 currently has a remaining life of 700 charge and discharge cycles, it can be considered that it will generate a profit of 47,600 yen in the future. At this time, the value notification unit 260 notifies the owner 80 that the future value of the battery 100 is “47,600 yen”. In addition, the value notification unit 260 notifies the owner 80 that a consideration of 10,200 yen has been paid to the owner 80 so far. Since it is considered that the battery 100 can generate a profit of 47,600 yen in the future, it can be evaluated that the battery 100 has a market value equivalent to the profit. Therefore, the owner 80 understands that by selling the battery 100 at the current point in time, it is possible to recover the investment amount.

In this way, the value notification unit 260 can calculate the value of the battery 100 based on the past use history data of the battery 100 and notify the owner 80 of the value. In addition, the value notification unit 260 may also refer to the battery information shown in FIG. 4 and consider attributes such as "region", "charging energy type", and "use item" to calculate the future value of the battery 100. For example, if the type of charging energy is “natural energy”, it may be possible to set a higher battery usage fee than other batteries by emphasizing the effect of contributing to energy saving and the like. In addition, it is possible to set the electricity bill for calculating the profit in consideration of the future power situation of the area where the battery 100 is used. For example, the value notification unit 260 may predict the future unit price of electricity purchase and the unit price of electricity sale based on the future forecast of solar power generation in the area where the battery 100 is used and changes in the purchase price of natural energy, and calculate the future revenue generated by the battery 100 . In addition, in the area where the battery 100 is used, the future revenue generated by the battery 100 can be calculated based on the future demand of the electric motorcycle using the battery 100.

In the above, the manner in which one owner 80 holds one battery 100 has been described. However, it is also possible to adopt a method in which a plurality of owners 80 share one battery 100. At this time, the consideration determination unit 220 may determine the consideration corresponding to the owner's investment ratio based on the profit generated by one battery 100.

In addition, it is also possible to adopt a method in which multiple owners have multiple batteries. At this time, the consideration determination unit 220 may determine the consideration corresponding to the owner's investment ratio based on the profit generated by the one set of charge and discharge every time one set of charge and discharge occurs in any battery.

In addition, the above has explained the profit calculation method in the manner of specifying the battery usage fee paid by the user 70 by a variable system corresponding to the amount of power supplied from the battery 100 to the user 70 and the period of battery lending. However, it is also possible to use the battery 100 to the user 70 The battery station 30 can be used for a fixed fee regardless of the amount of electricity provided to the user 70 and the loan period to the user 70. For example, assuming that the battery station 30 can be used with a monthly fixed fee of 1,000 yen, if the average number of battery exchanges per month is 10, the battery paid by the user 70 can be used The fee is regarded as "100 yen". Therefore, the consideration notification unit 240 may determine the profit by considering the amount calculated based on the fixed usage fee and the average number of battery exchanges as the battery usage fee. In addition, when the battery usage fee paid by the user 70 is specified by a combination of a fixed basic usage fee and a variable usage fee corresponding to the amount of electricity and/or the loan period, a combination of the above calculation methods can also be used. To calculate the battery usage fee.

In addition, a method in which the owner 80 of the battery 100 specifies the battery usage fee may also be adopted. For example, the value determining unit 210 may calculate the income obtained by lending to the user 70 based on information on the amount of electricity provided by the owner 80, the variable unit price during the lending period, and the fixed usage fee of the designated battery.

In addition, a method of directly transmitting information related to the charging and discharging of the battery 100 from the battery 100 to the management server 20 may be adopted. For example, the battery 100 may send information indicating the SOC, charge power, and discharge power of the battery 100 and the current position of the battery 100 to the management server 20. In this manner, the battery 100 can store at least a part of the information contained in the usage event information and the transaction information in an internal recording medium. In this manner, the battery station 30 can write information of the user 70 and the like into the battery 100 to send the information to the management server 20 through the battery 100. In addition, the electric motorcycle 40 can also read the information held in the battery 100 and send it to the management server 20.

In addition, a method in which the battery station 30 has at least a part of the function of the management server 20 may be adopted. In this way, the battery station 30 can use event information, submit At least a part of the information contained in e-info is sent to the blockchain network 180 for recording. According to this method, it is possible to reduce the management cost of information for using the battery 100 in some cases.

As described above, according to the exchange battery system 10, in a system that supplies power from a battery owned by a third party, it is possible to evaluate the appropriate consideration given to the owner of the battery.
