Further, at least a part of the processing by the server device 30 may be executed by the server device 10, or at least a part of the processing by the server device 10 may be executed by the server device 30.

[Functional configuration]
The functions of the server device 10 will be described with reference to FIG. 3. The server device 10 has a communication section 11, a database 12, and a control section 13 as main functional components.

The server device 10 may have other functional configurations that an information processing device such as a general information processing device or a dedicated device has. The functional configuration of the server device 10 is such that, for example, a control device such as a CPU (Central Processing Unit) included in the server device 10 reads and executes a computer program stored in a storage device, thereby processing a computer program (software) and hardware. This is realized through the cooperation of hardware.

The communication unit 11 receives and transmits various information through communication with external devices. For example, the communication unit 11 may transmit a control signal for controlling charging and power supply of the battery B to the terminal device 20 or the server device 30. The communication unit 11 may receive information corresponding to a user input to the terminal device 20 or the battery B from the terminal device 20 or the server device 30.

Further, the communication unit 11 may receive usage information indicating at least part of the usage period, charging status, or power supply status of the battery B from the terminal device 20 or the server device 30.

The database 12 stores various information including information received by the communication unit 11, information necessary for processing by the server device 10, or information generated by the server device 10. The database 12 may store, for example, optimization plan information indicating information regarding optimal charging of battery B or power supply by battery B. The optimization plan information may be stored in the database 12 based on information received from the terminal device 20 via the communication unit 11 in response to user input, for example.

The optimization plan information may include, for example, capacity information indicating the capacity for power supply for a predetermined power demand other than the vehicle EV, out of the dischargeable capacity of the battery B when charging is completed. Here, the predetermined power demand other than the vehicle EV is, for example, power demand other than the power demand of the vehicle EV, such as power for operating or driving the vehicle system of the vehicle EV and other on-vehicle equipment of the vehicle EV, It may also include the power demand of the above-mentioned power consumers. In this embodiment, the vehicle system is a system that drives a vehicle or operates an auxiliary device, and may include, for example, a motor or an engine. In the present embodiment, the predetermined power demand other than the vehicle EV may be, for example, power demand specified by the server device 10 receiving information. The capacity information may indicate the capacity for power supply to meet the power demand of the power consumer, out of the dischargeable capacity of the battery B when charging is completed.

The capacity information may be indicated by the absolute value (for example, Wh) of the capacity for power supply to meet the power demand of the power consumer among the dischargeable capacity at the time of completion of charging of battery B, or by the absolute value of the capacity (for example, Wh) of the dischargeable capacity Of these, the capacity may be expressed as a percentage (for example, %) of the capacity for power supply. The capacity information may include two types of capacity information (for example, an upper limit value and a lower limit value of the capacity (ratio) for power supply to a predetermined power demand), or may include three or more types of capacity information. .

The optimization plan information may include setting information regarding whether to set a charging completion time according to the time period in which the vehicle EV is driven regarding charging of the battery B. In addition, the optimization plan information includes a time period for charging battery B such that the amount of electricity billed for charging battery B is reduced based on rate information indicating a value corresponding to the electricity rate for each time period. It may also include setting information on whether to control or not. Furthermore, the optimization plan information is based on the demand information that is set according to the height of the predetermined power demand for each time period, and provides more preferential power supply for the predetermined power demand during the time period when the power demand is higher. It may also include setting information as to whether or not to perform.

The database 12 includes time zone information indicating a value according to the time zone in which the above-mentioned vehicle EV is operated, rate information indicating a value corresponding to the electricity rate for each time zone, or the height of a predetermined power demand for each time zone. At least a part of the demand information set according to the demand information may be stored.

The control unit 13 controls processing of various functions executed by the server device 10. For example, the control unit 13 may generate a control signal for controlling charging and power supply of battery B (that is, charging of battery B or power supply by battery B). The generated control signal may be transmitted to the terminal device 20 or the server device 30 via the communication unit 11, and charging and power supply of the battery B may be controlled. That is, the control unit 13 may control charging and power supply of the battery B. Further, the control unit 13 may control the battery B to supply power to a predetermined power demand (for example, the power consumer) based on the capacity information when the vehicle system of the vehicle EV is stopped.

That is, according to this embodiment, the server device 10 controls the battery B that can be mounted on the vehicle EV. Specifically, for example, the server device 10 includes a database 12 and a control unit 13. The database 12 may store capacity information indicating the capacity for supplying power to a predetermined power demand other than the vehicle EV (for example, the above-mentioned power consumer) out of the dischargeable capacity of the battery B when charging is completed. The control unit 13 may control the battery B to supply power for the predetermined power demand based on the capacity information when the vehicle system of the vehicle EV is stopped. In this way, when the vehicle system of the vehicle EV is stopped, the control unit 13 controls the battery B to supply power for the predetermined power demand based on the capacity information, thereby increasing the capacity of the battery of the vehicle EV. It is possible to utilize it more effectively.

Further, the server device 10 may control a plurality of batteries B. Specifically, for example, the database 12 stores, for each of the plurality of batteries B, the power supply for a predetermined power demand other than the vehicle EV (for example, the above-mentioned power consumer) out of the dischargeable capacity at the time of completion of charging of the battery B. Capacity information indicating the capacity for storage may be stored. The communication unit 11 may receive demand information indicating the capacity of the predetermined power demand. The control unit 13 may control each of the plurality of batteries B so that the battery B supplies power for a predetermined power demand based on the capacity information and the demand information. For example, the control unit 13 may control the plurality of batteries B so that more batteries B supply higher power when the demand information indicates a high power demand capacity.

At least some of the batteries B controlled by the server device 10 may be used batteries removed from the vehicle EV. At this time, the used battery plant 3 may be formed as a part of the virtual plant 2 as described above.

The capacity information is set using any method. For example, the capacity information may be set according to a user input of the terminal device 20, or may be set from the viewpoint of optimizing the life of the battery B.

The capacity information may include an upper limit value (e.g., 80 Wh) and a lower limit value (e.g., 20 Wh) of the capacity for power supply for a predetermined power demand among the dischargeable capacity of battery B upon completion of charging. In this case, the control unit 13 supplies power from battery B to a predetermined power demand up to a capacity corresponding to the upper limit value among the dischargeable capacity of battery B upon completion of charging, and then supplies power to a capacity corresponding to the lower limit value. Battery B may be controlled so as to charge battery B up to the maximum.

Generally, battery deterioration can be suppressed by keeping the charging rate within a predetermined range (for example, about 50% to 80%). Further, deterioration of the battery can be suppressed in some cases by refreshing the battery by discharging the stored power. Therefore, in order to refresh, the control unit 13 supplies power from battery B for a predetermined power demand to a capacity corresponding to the upper limit value (for example, 80%) of the dischargeable capacity of battery B at the time of completion of charging. Thereafter, deterioration of battery B can be suppressed by charging battery B to a capacity corresponding to the lower limit value (for example, 20%) and controlling the charging rate to be within a predetermined range.

The control unit 13 controls charging of the battery B so that charging is completed a predetermined time before the time period in which the vehicle EV is driven, based on time period information indicating a value corresponding to the time period in which the vehicle EV is driven. May be controlled. The "predetermined time before the time period in which the vehicle is operated" is arbitrarily set, and may be, for example, 10 minutes or 30 minutes before the start of operation. The time zone information may be, for example, information stored in a storage unit such as the database 12 based on information received via the communication unit 11. The time zone information may be, for example, information predicted based on the driving history of the vehicle EV received via the communication unit 11, or may be a set value received by the user via the communication unit 11. Alternatively, it may be based on the actual start time and end time of driving the vehicle EV. The time zone information may include, for example, information from 7:00 a.m. to 8:00 a.m. or from 6:00 p.m. to 7:00 p.m.

In this way, under the control of the control unit 13, charging is completed immediately before the time period in which the vehicle EV is driven, and the charging rate in the previous time period is maintained within a predetermined range (for example, about 50% to 80%). Therefore, deterioration of battery B can be suppressed.

The control unit 13 controls, based on the capacity information and the time zone information, to supply power from the battery B to meet the predetermined power demand of the power consumer or the like during a time zone when the vehicle EV is not operated. Good too. Thereby, the charging rate of battery B may be maintained within a predetermined range (for example, about 50% to 80%) during a time period when the vehicle EV is not driven.

The control unit 13 may control the time for charging the battery B so that the amount of electricity billed is reduced based on rate information indicating a value corresponding to the electricity rate for each time zone. The fee information may be, for example, information stored in a storage unit such as the database 12 based on information received via the communication unit 11. Electricity rates may vary depending on the time of day, such as being cheaper at night than during the day. In such a case, by controlling battery B to be charged during a time period when electricity rates are relatively low, the amount of electricity billed due to charging battery B can be reduced.

The control unit 13 controls a predetermined amount of power during a time period when the predetermined power demand is higher based on demand information indicating a value corresponding to the height of the predetermined power demand (for example, the power demand by the above-mentioned electricity consumer) for each time period. Battery B may be controlled so that power is supplied more preferentially than the power demand. The demand information may be, for example, information stored in a storage unit such as the database 12 based on information received via the communication unit 11. The demand information may be, for example, information based on actual power demand for each time period, or may be a predicted value of power demand for each time period.

In this way, the control unit 13 controls the electric power stored in the battery of the vehicle EV and not used to be supplied to the electric power consumer based on the demand information, so that it is possible to balance the electric power supply and demand. be.

The control unit 13 may specify optimization information including information regarding replacement of the battery B based on usage information indicating at least part of the usage period, charging status, or power supply status of the battery B. The usage information may be, for example, information stored in a storage unit such as the database 12 based on information received via the communication unit 11. The optimization information may include information regarding a recommended time to replace battery B with a new one, which is specified based on at least part of the usage period, charging status, or power supply status of battery B. The above-mentioned optimization information relates to the recommended optimal specifications (including, for example, battery capacity) of the battery after replacement, which is specified based on at least a part of the period of use, charging status, or power supply status of battery B. May contain information. The communication unit 11 may transmit the optimization information to the terminal device 20 of the user of battery B. The user of battery B may be able to check the optimization information via the display unit of the terminal device 20.

In the above, a method of controlling the charging and power supply of battery B using the functions of the server device 10 has been described, but the method is not limited to this, and the terminal device 20 or the server device 30 can charging and power supply may be controlled. For example, the terminal device 20 or the server device 30 each has a storage section and a control section. The storage unit stores capacity information indicating the capacity for power supply to a predetermined power demand other than the vehicle EV (for example, the above-mentioned power consumer) out of the dischargeable capacity of battery B upon completion of charging, and may control such that when the vehicle system of the vehicle EV is stopped, power is supplied from battery B for the predetermined power demand based on the capacity information. At least a part of the processing by the server device 10 described below may also be executed by the terminal device 20 or the server device 30.
