The value notification unit 260 may notify the owner 80 of the information representing the value generated by the battery 100 periodically 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 , after the battery 100 supplies electric power to the electric motorcycle 40 by discharging the electric power corresponding to 75% in SOC conversion, the electric motorcycle 40 is discharged with the electric power corresponding to 75% in SOC conversion. , resulting in a profit of 48 yen, and a consideration of 24 yen is given to the owner 80. In addition, the battery 100 discharges electric power to the grid 160 by discharging the electric power equivalent to 25% in the SOC conversion, and then charges the electric power equivalent to 25% in the SOC conversion, generating a profit of 20 yen, and The owner 80 is given a consideration of 10 yen. Therefore, by charging and discharging one cycle, 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 per one cycle, and if 300 cycles of charging and discharging have been performed so far, a consideration of 10,200 yen is given to the owner 80 so far. Assume that the owner 80 invests 55,000 yen to purchase the battery 100 . Also, assume 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-discharge cycles, it can be considered that a profit of 47,600 yen will be generated 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 given to the owner 80 so far. Considering that the battery 100 can generate a profit of 47,600 yen in the future, it can be estimated that the battery 100 has a market value corresponding to the profit. Therefore, the owner 80 understands that it is possible to recover the investment amount by selling the battery 100 at the current point in time.

Thereby, the value notification unit 260 can calculate the value of the battery 100 based on the past usage history data of the battery 100 and notify the owner 80 of the value. In addition, the value notification unit 260 may calculate the value generated by the battery 100 in the future by referring to the battery information shown in FIG. For example, if the charging energy type is "natural energy", there are cases where a higher battery usage fee can be set than other batteries by emphasizing effects such as contributing to energy saving. In addition, the electricity bill for calculating the profit can be set in consideration of the future electric power situation in the area where the battery 100 is used. For example, the value notification unit 260 may predict the future electricity purchase unit price and the electricity sale unit price based on the future forecast of the solar power generation amount in the area where the battery 100 is used and the change in the purchase price of natural energy, and calculate the future profit generated by the battery 100 . In addition, in the region where the battery 100 is used, the future profit of the battery 100 can be calculated based on the future demand of the electric motorcycle using the battery 100 .

The manner in which one owner 80 holds one battery 100 has been described above. 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 investment ratio of the owner based on the profit generated by one battery 100 .

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

In addition, the profit calculation method in which the battery usage fee paid by the user 70 is defined by the fluctuation system corresponding to the amount of electricity supplied from the battery 100 to the user 70 and the battery lending period has been described above. However, it is also possible to use the The battery station 30 can be used at a fixed usage fee irrespective of the power supply of the battery and the loan period to the user 70 . For example, if it is assumed that the battery station 30 can be used at a fixed usage fee of 1,000 yen per month, the battery paid by the user 70 can be used if the average number of battery exchanges per month is 10 times. The fee is regarded as "100 yen". Therefore, the price 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, in the case where the battery usage fee paid by the user 70 is defined by a combination of a fixed basic usage fee and a fluctuating usage fee corresponding to the amount of electricity and/or the loan period, a combination of the above-mentioned calculation methods may be used. to calculate battery usage charges.

Alternatively, the owner 80 of the battery 100 may designate the battery usage fee. For example, the value determination unit 210 may calculate the profit obtained by lending to the user 70 based on the information of the supplied electric quantity specified for the owner 80 , the fluctuating unit price during the lending period, and the fixed usage fee of the specified battery.

In addition, a method of directly transmitting the information on the charge and discharge of the battery 100 from the battery 100 to the management server 20 may be employed. For example, the battery 100 may transmit information indicating the SOC, the charge level, the discharge level, and the current position of the battery 100 to the management server 20 . In this manner, the battery 100 can retain at least a part of the information contained in the usage event information and the transaction information in the internal recording medium. In this manner, the battery station 30 can transmit the information of the user 70 and the like to the management server 20 through the battery 100 by writing the information of the user 70 and the like into the battery 100 . In addition, the electric motorcycle 40 may read out the information held in the battery 100 and transmit it to the management server 20 .

Alternatively, the battery station 30 may include at least a part of the functions of the management server 20 . In this manner, the battery station 30 can use event information, submit At least a portion of the information contained in the easy information is sent to the blockchain network 180 for recording. According to this aspect, the management cost of the information for using the battery 100 can be reduced in some cases.

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