[0008] A control device according to one aspect of the present disclosure is configured to perform sequence processing with a mobile object and to control a charging / discharging device that charges and discharges a storage battery of the mobile object. After power transfer between the mobile object and the charging / discharging device is permitted in the sequence processing, the control device controls the charging / discharging device so that the charging / discharging device charges and discharges the storage battery. When at least one of a state in which a power value of charging power of the storage battery is equal to or less than a first threshold and a state in which a power value of discharging power of the storage battery is equal to or less than a second threshold continues for a predetermined period of time, the control device stops the sequence processing before receiving a request to stop the sequence processing from the mobile object.

[0009] A control method according to one aspect of the present disclosure is a control method for performing sequence processing with a mobile object and controlling a charging / discharging device that charges and discharges a storage battery of the mobile object. The control method includes a first process and a second process.

In the second process, if at least one of a state in which a power value of charging power of the storage battery is equal to or less than a first threshold or a state in which a power value of discharging power of the storage battery is equal to or less than a second threshold continues for a predetermined period of time, the sequence processing is stopped before receiving a request to stop the sequence processing from the mobile object.

[0010] Another control device according to one aspect of the present disclosure is configured to perform sequence processing with a mobile object and control a charging / discharging device that charges and discharges a storage battery of the mobile object. The control device controls the charging / discharging device so that the charging / discharging device charges and discharges the storage battery after the sequence processing allows power to be exchanged between the mobile object and the charging / discharging device. When at least one of a state in which a power value of the charging power of the storage battery is equal to or less than a first threshold and a state in which a power value of the discharging power of the storage battery is equal to or less than a second threshold continues for a predetermined period of time, the control device controls the charging / discharging device to forcibly charge and discharge the storage battery so that the power value of the charging power or the discharging power becomes equal to or greater than the first threshold or the second threshold before receiving a request to stop the sequence processing from the mobile object.

[0011] Another control method according to one aspect of the present disclosure is a control method for performing sequence processing with a mobile object and controlling a charging / discharging device that charges and discharges a storage battery of the mobile object.

[0015] Hereinafter, charging / discharging systems according to embodiments 1 and 2 will be described with reference to the drawings. Note that the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0016] (Embodiment 1) A charge / discharge system A1 according to the first embodiment will be described below with reference to FIGS.

[0017] (1) Charging and discharging system The charge / discharge system A1 includes a charge / discharge device 1, a control device 2, a power storage device 10, a power device 20, a solar cell module 30, and a remote control 40, as shown in FIG.

[0018] The charge / discharge system A1 is electrically connected to, for example, a mobile object 100, and charges a storage battery (first storage battery) 101 of the mobile object 100. The mobile object 100 is, for example, a vehicle (e.g., an electric vehicle) and has the first storage battery 101. The first storage battery 101 is, for example, a lithium-ion battery. The charge / discharge system A1 also discharges, for example, the first storage battery 101, and supplies the power stored in the first storage battery 101 to the power storage device 10 and a distribution board 80, which will be described later. Note that the first storage battery 101 is not limited to a lithium-ion battery, and may be, for example, a nickel-metal hydride battery, a lead battery, or the like.

[0019] (2) Components of the charging / discharging system (2.1)Charge / discharge device The charging / discharging device 1 charges and discharges a first storage battery 101 of a mobile object 100. The charging / discharging device 1 is electrically connected to the first storage battery 101. The charging / discharging device 1 is also electrically connected to a power storage device 10 and a power device 20.

[0020] (2.2) Control device The control device 2 is realized, for example, by a computer system having one or more processors and one or more memories. In other words, the functions of the control device 2 are realized by the one or more processors executing a program recorded in the memory. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided. The control device 2 is electrically connected to the charging / discharging device 1, the power device 20, and the power storage device 10. The control device 2 is also electrically connected to the mobile object 100. Note that the control device 2 is not limited to being realized by a computer having one or more processors and one or more memories, and may be realized, for example, by a processor composed of multiple components, or may be realized by a single processor combined with other functions and configurations.

[0021] The control device 2 controls, for example, the charging / discharging device 1. More specifically, the control device 2 controls, for example, the charging / discharging device 1 so that the charging / discharging device 1 charges and discharges the first storage battery 101.

[0022] The control device 2 also communicates with the mobile object 100. For example, the control device 2 communicates with the mobile object 100 via CAN (Controller Area Network). For example, the control device 2 transmits and receives signals including information related to processing to be performed with the mobile object 100. The control device 2 also performs sequence processing with the mobile object 100. More specifically, the control device 2 performs sequence processing with a controller of the mobile object 100. The controller of the mobile object 100 is, for example, an ECU (Electronic Control Unit). Note that the sequence processing is processing performed between the control device 2 and the mobile object 100, and refers to, for example, a series of processing including a plurality of processing steps in which an order is defined for starting or stopping the exchange of power between the mobile object 100 and the charging / discharging device 1.

[0023] The control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 charges / discharges the first storage battery 101 after the transfer of power between the moving object 100 and the charging / discharging device 1 is permitted in the sequence processing.

[0024] Incidentally, when the power value of the charging power of the first storage battery 101 remains equal to or less than a first threshold P1 (see FIG. 3) for a certain period (hereinafter referred to as the "first period"), the mobile object 100 requests the stop of the sequence processing performed between the mobile object 100 and the control device 2. The first threshold P1 is, for example, 1 kW. Furthermore, when the power value of the discharging power of the first storage battery 101 remains equal to or less than a second threshold P2 (see FIG. 3) for a certain period (hereinafter referred to as the "second period"), the mobile object 100 requests the stop of the sequence processing. The second threshold P2 is, for example, 1 kW. Note that the "power value of the charging power of the first storage battery 101" refers to the power value (positive value) of the power when the charging / discharging device 1 charges the first storage battery 101. Furthermore, the "power value of the discharging power of the first storage battery 101" refers to the power value (positive value) of the power when the charging / discharging device 1 discharges the first storage battery 101. The power values ​​of the charging power and discharging power of the first storage battery 101 are positive values, but in Fig. 3, in order to make it easier to visually understand the charging state and discharging state of the first storage battery 101, the power value of the charging power of the first storage battery 101 is expressed as a positive value and the power value of the discharging power of the first storage battery 101 is expressed as a negative value. Furthermore, the first threshold value P1 and the second threshold value P2 are positive values, but in Fig. 3, in order to make it easier to visually understand the charging state and discharging state of the first storage battery 101, the first threshold value P1 is expressed as a positive value and the second threshold value P2 is expressed as a negative value.

[0025] The first period is, for example, five minutes, and is a period from time t3 to time t5 in FIG. 3. The second period is, for example, a period of the same length as the first period, and is a period from time t7 to time t9 in FIG. 3. The second threshold P2 is, for example, the same value (absolute value) as the first threshold P1. Note that the second period is a period of the same length as the first period, but may be a period of a different length.

[0026] The mobile object 100 requests the stop of the sequence processing when the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold value P1 for a first period of time, and when the power value of the discharging power of the first storage battery 101 remains equal to or less than the second threshold value P2 for a second period of time. Specifically, the controller of the mobile object 100 transmits a signal (stop request signal) to the control device 2 to request the stop of the sequence processing when, for example, the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold value P1 for a first period of time, and when the power value of the discharging power of the first storage battery 101 remains equal to or less than the second threshold value P2 for a second period of time.

[0027] Furthermore, the mobile object 100 requests the stop of the sequence processing when both a state in which the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold value P1 and a state in which the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold value P2 (for example, both states consecutively) continue for a third period. Specifically, the controller of the mobile object 100 transmits a stop request signal to the control device 2 when, for example, a state in which the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold value P1 and a state in which the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold value P2 continue for a third period.

[0028] Here, the controller of the moving body 100 times one of the first period, the second period, and the third period to determine whether or not to transmit a stop request signal to the control device 2. That is, the first period, the second period, and the third period are periods (timed periods) timed by the controller of the moving body 100. The timed period differs depending on, for example, the type of the moving body 100. Note that the first period, the second period, and the third period are, for example, the same period.

[0029] 1 also communicates with the power device 20. The control device 2 transmits and receives signals including information about the charging / discharging device 1 (for example, setting information), for example.

[0030] The control device 2 also controls, for example, the power storage device 10. More specifically, the control device 2 controls, for example, a power conversion device 11, which will be described later, in the power storage device 10. The control device 2 also controls the charging / discharging device 1 and the power conversion device 11 when power is exchanged between the first storage battery 101 and a second storage battery 12, which will be described later, in the power storage device 10. In other words, the control device 2 controls the charging / discharging device 1 and the power conversion device 11 when charging / discharging is performed between the first storage battery 101 and the second storage battery 12.

[0031] (2.3) Energy storage device The power storage device 10 is, for example, a device that stores power generated by a power generation device (in the example of FIG. 1, a solar cell module 30). The power storage device 10 includes, for example, a power conversion device 11 and a second storage battery 12. The second storage battery 12 is, for example, a lithium ion battery. Note that the second storage battery 12 is not limited to a lithium ion battery, and may be, for example, a nickel-metal hydride battery, a lead battery, or the like.

[0032] The power conversion device 11 converts first DC power into second DC power. The power conversion device 11 converts the first DC power from at least one of the charging / discharging device 1 and the power device 20 into second DC power, and supplies the second DC power to the second storage battery 12. The power conversion device 11 also converts the second DC power into first DC power. The power conversion device 11 converts the second DC power from the second storage battery 12 into first DC power, and supplies the first DC power to at least one of the charging / discharging device 1 and the power device 20. In short, the power conversion device 11 is a bidirectional converter (bidirectional DC-DC converter). The power conversion device 11 is electrically connected to the second storage battery 12, the charging / discharging device 1, and the power device 20.

[0033] (2.4) Power equipment The power device 20 includes, for example, a first power conversion device 21, a second power conversion device 22, and a power control device 23.

[0034] The first power conversion device 21 converts first DC power into first AC power. The first power conversion device 21 converts the first DC power from at least one of the charging / discharging device 1 and the power storage device 10 into first AC power, and supplies the first AC power to at least one of the distribution board 80 and the power grid 90. The first power conversion device 21 also converts the first AC power into first DC power. The first power conversion device 21 converts the first AC power from at least one of the distribution board 80 and the power grid 90 into first DC power, and supplies the first DC power to at least one of the charging / discharging device 1 and the power storage device 10. In short, the first power conversion device 21 is a bidirectional converter (bidirectional AC-DC converter). The first power conversion device 21 is electrically connected to the charging / discharging device 1, the power conversion device 11, and the second power conversion device 22. The first power conversion device 21 is electrically connected to a distribution board 80 via a power switching unit 70 (described later). The first power conversion device 21 is electrically connected to a power grid 90 via the power switching unit 70.

[0035] The power switching unit 70 is a device that electrically connects the first power conversion device 21 to the distribution board 80 or the power system 90. For example, in accordance with an instruction from the power control device 23 of the power device 20, the power switching unit 70 switches between one of a first connection state in which the first power conversion device 21 is electrically connected to the distribution board 80 and a second connection state in which the first power conversion device 21 is electrically connected to the power system 90.

[0036] The distribution board 80 is electrically connected to the power system 90 via the power switching unit 70. The distribution board 80 is also electrically connected to the first power conversion device 21 via the power switching unit 70. One or more loads are connected to the distribution board 80. The loads are, for example, lighting fixtures, electrical equipment, hot water supply equipment, electrical outlets, wiring devices, etc. The wiring devices are, for example, wall switches, etc.

[0037] The power system 90 is, for example, a commercial power supply. The power system 90 supplies the second AC power to at least one of the power device 20 and the distribution board 80.

[0038] The second power conversion device 22 converts the third DC power into the first DC power. The second power conversion device 22 is a DC-DC converter. The second power conversion device 22 converts the third DC power from the solar cell module 30 into the first DC power and supplies the first DC power to at least one of the first power conversion device 21, the charge / discharge device 1, and the power conversion device 11. The second power conversion device 22 is electrically connected to the first power conversion device 21, the charge / discharge device 1, and the power conversion device 11. The second power conversion device 22 is also electrically connected to the solar cell module 30.

[0039] The power control device 23 is realized, for example, by a computer system having one or more processors and one or more memories. That is, the functions of the power control device 23 are realized by the one or more processors executing a program stored in the memory. The program may be pre-stored in the memory, provided via a telecommunications line such as the Internet, or provided by being recorded on a non-transitory recording medium such as a memory card. The power control device 23 is electrically connected to the first power conversion device 21 and the second power conversion device 22. The power control device 23 is also electrically connected to the remote control 40, the control device 2, and the power switching unit 70.

[0040] The power control device 23 controls, for example, the first power conversion device 21 and the second power conversion device 22. The power control device 23 also accepts operations from a remote control 40. For example, the power control device 23 accepts a change in the settings of the charging / discharging device 1 from the remote control 40. When the power control device 23 accepts a change in the settings of the charging / discharging device 1 from the remote control 40, it transmits a signal including information related to the change in the settings of the charging / discharging device 1 to the control device 2. Note that the power control device 23 is not limited to only accepting changes in the settings of the charging / discharging device 1 from the remote control 40, but also accepts changes in the settings of the charging / discharging system A1 from the remote control 40.

[0041] (2.5) Solar Cell Module The solar cell module 30 includes, for example, a plurality of solar cells. The plurality of solar cells generate power using sunlight. The plurality of solar cells supply the generated power (third DC power) to the second power conversion device 22. In other words, the solar cell module 30 supplies the third DC power to the second power conversion device 22. The solar cell module 30 is electrically connected to the second power conversion device 22. Note that the number of solar cells is plural, but may be one.

[0042] (2.6) Remote Control The remote controller 40 is configured to be able to change settings of the charging / discharging system A1, for example. The remote controller 40 includes a display unit 41, an operation unit 42, and a control unit, as shown in FIG.

[0043] The display unit 41 is, for example, a display (for example, a liquid crystal display). The display unit 41 is electrically connected to the control unit. The display unit 41 displays information from the control unit. In the example of FIG. 2, information (setting information) related to the type (vehicle type) of the moving body 100 is displayed on the display unit 41.

[0044] The operation unit 42 is configured to be able to change, for example, information (for example, setting information) displayed on the display unit 41. The operation unit 42 is, for example, an operation button. The operation unit 42 is electrically connected to the control unit.

[0045] The control unit transmits, for example, a signal including information regarding the setting change to the power control device 23 of the power device 20. The control unit is realized, for example, by a computer system having one or more processors and one or more memories. That is, the functions of the control unit are realized by the one or more processors executing a program recorded in the memory. The program may be pre-recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0046] (3) Operation of the charging / discharging system As shown in FIG. 3, the control device 2 shown in FIG. 1 stops the sequence processing performed between the control device 2 and the mobile object 100 before receiving a request to stop the sequence processing from the mobile object 100 (more specifically, before receiving a stop request signal from the mobile object 100) if the power value of the charging power of the first storage battery 101 remains equal to or less than a first threshold value P1 for a predetermined period T1. Furthermore, if the power value of the discharging power of the first storage battery 101 remains equal to or less than a second threshold value P2 for a predetermined period T2, the control device 2 stops the sequence processing before receiving a request to stop the sequence processing from the mobile object 100. The predetermined period T1 is, for example, 4 minutes and 45 seconds. The predetermined period T2 is, for example, the same period as the predetermined period T1. The first threshold value P1 and the second threshold value P2 are pre-stored in the memory of the control device 2.

[0047] Time t1 in FIG. 3 represents the time when the control device 2 starts the sequence processing. Time t2 in FIG. 3 represents the time when the transfer of power between the mobile object 100 and the charging / discharging device 1 is permitted. Time t3 in FIG. 3 represents the time when the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold P1. Time t4 in FIG. 3 represents the time when the control device 2 stops the sequence processing after the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold P1 for a predetermined period T1. Time t5 in FIG. 3 represents the time when the mobile object 100 transmits a stop request signal to the control device 2 after the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold P1 for a first period. Time t6 in FIG. 3 represents the time when the control device 2 resumes the sequence processing. Time t7 in FIG. 3 represents the time when the power value of the discharging power of the first storage battery 101 remains equal to or less than the second threshold P2. 3 indicates the time when the state in which the power value of the discharged power of the first storage battery 101 is equal to or less than the second threshold P2 continues for a predetermined period T2, and the control device 2 stops the sequence processing. Time t9 in Fig. 3 indicates the time when the moving object 100 transmits a stop request signal to the control device 2 when the state in which the power value of the discharged power of the first storage battery 101 is equal to or less than the second threshold P2 continues for a second period.

[0048] When the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold P1 for a predetermined period T1, or when the power value of the discharging power of the first storage battery 101 remains equal to or less than the second threshold P2 for a predetermined period T2, the control device 2 stops the sequence processing before receiving a request to stop the sequence processing from the mobile object 100. In other words, when the power values ​​of the charging power and discharging power of the first storage battery 101 are small, the charging efficiency and discharging efficiency of the first storage battery 101 may deteriorate, which may cause the mobile object 100 to transmit a stop request signal to the control device 2, so the control device 2 stops the sequence processing before receiving the stop request signal from the mobile object 100.

[0049] The control device 2 stops the sequence processing before receiving a request to stop the sequence processing from the moving object 100 when the state in which the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold P1 continues for a predetermined period T1, but may stop the sequence processing before receiving a request to stop the sequence processing from the moving object 100 when both states (e.g., both consecutive states) of the state in which the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold P1 and the state in which the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold P2 continue for the predetermined period T1 or a predetermined period T2. In other words, the control device 2 may stop the sequence processing before receiving a request to stop the sequence processing from the moving object 100 when at least one of the states in which the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold P1 and the state in which the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold P2 continues for the predetermined period T1 or a predetermined period T2.

[0050] Incidentally, if a stop request signal is transmitted from the mobile object 100 while the charging / discharging system A1 is charging / discharging the first storage battery 101 (when the mobile object 100 stops the sequence processing performed between the mobile object 100 and the control device 2), the control device 2 may enter a state in which it cannot operate. Therefore, when the charging / discharging system A1 is charging / discharging the first storage battery 101 and the power values ​​of the charging power and discharging power of the first storage battery 101 are small, the charging / discharging system A1 stops the sequence processing before receiving the stop request signal from the mobile object 100. As a result, in the charging / discharging system A1, for example, while the first storage battery 101 is being charged / discharged, the mobile object 100 does not stop the sequence processing, and it is possible to avoid a state in which the control device 2 cannot operate. Therefore, the charging / discharging system A1 can continue to operate continuously. Note that the "state in which the control device 2 cannot operate" refers to, for example, a state in which the control device 2 cannot control the power storage device 10 to charge / discharge the second storage battery 12 unless the control device 2 receives a stop request signal from the mobile object 100 and accepts a user operation on the remote control 40.

[0051] Furthermore, if a stop request signal is transmitted from the mobile object 100 while the first storage battery 101 is being charged or discharged, the connector of the charge / discharge cable connected to the mobile object 100 may be unlocked, possibly causing the charge / discharge cable to become unplugged from the mobile object 100. Therefore, as described above, while the first storage battery 101 is being charged or discharged, if the power values ​​of the charge power and discharge power of the first storage battery 101 are small, the charge / discharge system A1 stops the sequence processing before receiving the stop request signal from the mobile object 100. As a result, while the first storage battery 101 is being charged or discharged, the charge / discharge system A1 prevents the mobile object 100 from stopping the sequence processing and does not unlock the connector of the charge / discharge cable, thereby preventing the charge / discharge cable from becoming unplugged from the mobile object 100.

[0052] Furthermore, if the mobile object 100 stops the sequence processing while the charging / discharging system A1 is charging / discharging the first storage battery 101, for example, the user needs to disconnect the connector of the charging / discharging cable from the mobile object 100 after the operation of the charging / discharging system A1 itself stops. However, in the charging / discharging system A1, the mobile object 100 does not stop the sequence processing, so the user does not need to disconnect the connector of the charging / discharging cable from the mobile object 100. In other words, the charging / discharging system A1 can continue to operate without bothering the user.

[0053] Furthermore, the control device 2 of the charging / discharging system A1 is configured to perform sequence processing with the mobile object 100 and to control the charging / discharging device 1 that charges and discharges the first storage battery 101 of the mobile object 100, as described above. As described above, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 charges and discharges the first storage battery 101 after the transfer of power between the mobile object 100 and the charging / discharging device 1 is permitted in the sequence processing. Furthermore, as described above, the control device 2 stops the sequence processing before receiving a request to stop the sequence processing from the mobile object 100 when at least one of the states where the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold value P1 and the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold value P2 continues for a predetermined period T1 or a predetermined period T2. This allows the control device 2 to continue operating continuously, similar to the above-described charging / discharging system A1.

[0054] The control method for the charging / discharging system A1 is a control method for controlling the charging / discharging device 1 that performs sequence processing with the mobile object 100 and charges / discharges the first storage battery 101 of the mobile object 100. The control method includes a first process and a second process. In the first process, after the transfer of power between the mobile object 100 and the charging / discharging device 1 is permitted in the sequence processing, the charging / discharging device 1 is controlled so that the charging / discharging device 1 charges / discharges the first storage battery 101. In the second process, if at least one of a state in which the power value of the charging power of the first storage battery 101 is equal to or less than a first threshold value P1 or a state in which the power value of the discharging power of the first storage battery 101 is equal to or less than a second threshold value P2 continues for a predetermined period T1 or a predetermined period T2, the sequence processing is stopped before a request to stop the sequence processing is received from the mobile object 100. In other words, the control method is a control method for realizing the charging / discharging system A1. Therefore, the control method allows the charging / discharging system A1 to continue operating continuously, similar to the above-described charging / discharging system A1.

[0055] The above control method is realized by one or more processors executing a program (computer program). This program is, for example, a program for causing one or more processors of the control device 2 to execute the above control method. Therefore, according to the above program, like the above control method, the charging / discharging system A1 can continue to operate continuously.

[0056] 2 is configured to be able to change, for example, whether or not the first threshold value P1 and the second threshold value P2 are set. Furthermore, when the first threshold value P1 and the second threshold value P2 are set, the remote control 40 is configured to be able to change the values ​​of the first threshold value P1 and the second threshold value P2. This allows the charging / discharging system A1 to enable or disable the settings of the first threshold value P1 and the second threshold value P2, for example, based on the user's operation of the remote control 40. Furthermore, the charging / discharging system A1 can change the first threshold value P1 and the second threshold value P2 based on the user's operation of the remote control 40. In other words, the charging / discharging system A1 can meet various user needs.

[0057] The remote control 40 is also configured to be able to select the type of the moving object 100 (in the example of FIG. 2, a vehicle model type ID). The remote control 40, for example, determines whether or not to set the first threshold value P1 and the second threshold value P2 and changes the values ​​of the first threshold value P1 and the second threshold value P2 according to the type of the selected moving object 100. As a result, in the charging / discharging system A1, for example, the user can simply select the type of moving object 100 displayed on the display unit 41 to set the first threshold value P1 and the second threshold value P2 appropriate for the type of moving object 100. That is, in the charging / discharging system A1, optimal parameters (e.g., the first threshold value P1 and the second threshold value P2) corresponding to the vehicle model of the moving object 100 owned by the user can be set. For example, in the charging / discharging system A1, if the moving object 100 is a vehicle model with high power consumption, the first threshold value P1 is set higher and the second threshold value P2 is set lower than if the moving object 100 is a vehicle model with low power consumption. Note that the "vehicle model type ID" refers to, for example, an identification number used to identify a vehicle model by each automobile manufacturer.

[0058] The control device 2 shown in FIG. 1 may be configured to measure a period (the first period) from the time when the power value of the charging power of the first storage battery 101 reaches a first threshold P1 (time t3 in the example of FIG. 3) to the time when a request to stop the sequence processing is received from the mobile object 100 (time t5 in the example of FIG. 3). Alternatively, the control device 2 may be configured to measure a period (the second period) from the time when the power value of the discharging power of the first storage battery 101 reaches a second threshold P2 (time t7 in the example of FIG. 3) to the time when a request to stop the sequence processing is received from the mobile object 100 (time t9 in the example of FIG. 3). In this case, the control device 2 sets the predetermined period T1 and the predetermined period T2 to periods shorter than the measured first period and second period. This reliably prevents the charge / discharge system A1 from being unable to operate. Therefore, the charge / discharge system A1 can continue to operate continuously. In addition, the control device 2 is not limited to a configuration that measures the first period and the second period, but may also be configured, for example, to receive information on the first period and the second period from the mobile body 100 before the exchange of power between the mobile body 100 and the charging / discharging device 1 is permitted in the sequence processing.

[0059] The control device 2 shown in FIG. 1 resumes the sequential processing when, for example, the power value (first power value) of the power supplied from the power storage device 10 to the power grid 90, i.e., the so-called reverse flow power of the power grid 90, is equal to or greater than a third threshold P3 (see FIGS. 4 and 5). Furthermore, the control device 2 resumes the sequential processing when, for example, the power value (second power value) of the power supplied from the power grid 90 to the distribution board 80, i.e., the so-called forward flow power of the power grid 90, is equal to or less than a fourth threshold P4 (see FIGS. 4 and 5). The fourth threshold P4 is a value smaller than the third threshold P3. The third threshold P3 is set larger than the first threshold P1 (see FIG. 3). The fourth threshold P4 is set smaller than the second threshold P2 (see FIG. 3). The third threshold P3 and the fourth threshold P4 are pre-stored in the memory of the control device 2. The "reverse flow power of the power system 90" includes, for example, power (sold power) at the power receiving point (power switching unit 70 in the example of FIG. 1) when power is supplied from the power storage device 10 to the power system 90. Also, the "forward flow power of the power system 90" includes, for example, power (purchased power) at the power receiving point when power is supplied from the power system 90 to the distribution board 80.

[0060] That is, after stopping the sequential processing, the control device 2 resumes the sequential processing when the power value of the power grid 90 (e.g., backward flow power) becomes equal to or greater than the third threshold P3 and the power of the entire charging / discharging system A1 is in surplus (e.g., when enough power to charge the first storage battery 101 is secured). Furthermore, after stopping the sequential processing, the control device 2 resumes the sequential processing when the power value of the power grid 90 (e.g., forward flow power) becomes equal to or less than the fourth threshold P4 and the power of the entire charging / discharging system A1 is insufficient (e.g., when the second storage battery 12 is at its lower discharge limit). As a result, in the charging / discharging system A1, the sequential processing can be automatically resumed after the sequential processing has been stopped, without the user having to operate the remote control 40, for example. Therefore, in the charging / discharging system A1, the sequential processing can be automatically resumed, for example, when the charging efficiency and discharging efficiency of the first storage battery 101 improve (e.g., when the power of the entire charging / discharging system A1 is in surplus). That is, in the charging / discharging system A1, it is possible to frequently stop the sequence processing. Therefore, in the charging / discharging system A1, it is possible to reduce the power consumption of the mobile object 100. Furthermore, in the charging / discharging system A1, the third threshold P3 is set to be larger than the first threshold P1 and the fourth threshold P4 is set to be smaller than the second threshold P2, so that, for example, it is possible to prevent the sequence processing from being stopped immediately after it is resumed. Therefore, in the charging / discharging system A1, it is possible to efficiently charge and discharge, for example, the first storage battery 101. That is, the charging / discharging system A1 can operate efficiently and further reduce power consumption.

[0061] The term "surplus power" refers to the power remaining after subtracting the power consumed by one or more loads connected to the distribution board 80 (power consumption of one or more loads) from the power generated by a power generation device such as the solar cell module 30 (power generation power of the power generation device). The term "power shortage" refers to the power remaining after subtracting the power generated by the power generation device from the power consumption of one or more loads. The term "when the second storage battery 12 is at its lower discharge limit" includes, for example, a state in which the state of charge (SOC) of the second storage battery 12 is 20% or less. Time t16 in FIG. 4 represents the time when the first power value of the reverse flow power of the power grid 90 reaches the third threshold P3. Time t17 in FIG. 4 represents the time when the second power value of the forward flow power of the power grid 90 reaches the fourth threshold P4. Time t18 in FIG. 5 represents the time when the first power value of the reverse flow power of the power grid 90 reaches the third threshold P3 and the control device 2 resumes the sequence processing. Time point t19 in Fig. 5 represents the time point when the control device 2 stops the sequence processing. Time point t20 in Fig. 5 represents the time point when the second power value of the forward flow power of the power system 90 reaches the fourth threshold P4 and the control device 2 resumes the sequence processing. Time point t21 in Fig. 5 represents the time point when the control device 2 stops the sequence processing.

[0062] Here, the control device 2 may resume the sequence processing when the period during which the first power value is equal to or greater than the third threshold P3 is equal to or greater than the first predetermined period. The control device 2 may resume the sequence processing when the period during which the second power value is equal to or less than the fourth threshold P4 is equal to or greater than the second predetermined period. The second predetermined period is, for example, the same as the first predetermined period. The second predetermined period may be, for example, the same as the predetermined period T2 or a different period from the predetermined period T2. This can further prevent the sequence processing from being stopped immediately after it is resumed in the charging / discharging system A1. Therefore, the charging / discharging system A1 can charge / discharge the first storage battery 101 more efficiently. This means that the charging / discharging system A1 can operate more efficiently and further reduce power consumption. The first predetermined period and the second predetermined period are pre-stored in the memory of the control device 2. The second predetermined period is the same as the first predetermined period, but may be a different period. In the example of Figure 5, the control device 2 resumes sequence processing when the power value of the reverse flow power of the power system 90 becomes equal to or greater than the third threshold P3 and when the power value of the forward flow power of the power system 90 becomes equal to or less than the fourth threshold P4, so the first and second specified periods are not shown in Figure 5.

[0063] 6, for example, when the number of restarts of the sequence processing within a specified period (first specified period) T5 is equal to or greater than a predetermined number (first predetermined number), the control device 2 changes the third threshold P3 (see FIGS. 4 and 5) so as to increase (become a larger value), and changes the fourth threshold P4 (see FIGS. 4 and 5) so as to decrease (become a smaller value). In other words, when the control device 2 determines that the number of restarts of the sequence processing within the first specified period T5 is equal to or greater than the first predetermined number, the control device 2 changes the third threshold P3 so as to increase (become a larger value) than the value at the time of determination, and changes the fourth threshold P4 so as to decrease (become a smaller value) than the value at the time of determination. The first specified period T5 is, for example, half a day. Furthermore, when the number of restarts of the sequential processing within the first specified period T5 is less than the first predetermined number of times, the control device 2 changes the third threshold P3 so as to decrease the third threshold P3 and changes the fourth threshold P4 so as to increase the fourth threshold P4. In other words, when the control device 2 determines that the number of restarts of the sequential processing within the first specified period T5 is less than the first predetermined number of times, the control device 2 changes the third threshold P3 so as to decrease the third threshold P3 from its value at the time of determination and changes the fourth threshold P4 so as to increase the fourth threshold P4 from its value at the time of determination. In short, when the number of restarts of the sequential processing within the first specified period T5 is equal to or greater than the first predetermined number of times, the control device 2 changes the values ​​of the third threshold P3 and the fourth threshold P4 so as not to increase the number of restarts of the sequential processing. Furthermore, when the number of restarts of the sequential processing within the first specified period T5 is less than the first predetermined number of times, the control device 2 changes the values ​​of the third threshold P3 and the fourth threshold P4 so as to increase the number of restarts of the sequential processing. The first specified period T5 and the first predetermined number of times are stored in advance in the memory of the control device 2. The first specified period T5 is not limited to half a day, and may be, for example, one day. Time points t22 to t27 in Fig. 6 represent the times when the control device 2 resumes the sequence processing. The example in Fig. 6 also represents the number of times the sequence processing is executed and resumed in half a day, and represents a case where the sequence processing is executed seven times.

[0064] For example, when the first predetermined number of times is set to six, the control device 2, when the number of times the sequence process is restarted within the first specified period T5 is six, changes the third threshold P3 to a larger value and changes the fourth threshold P4 to a smaller value, as shown in Fig. 6. Furthermore, when the number of times the sequence process is restarted within the first specified period T5 is four, the control device 2 changes the third threshold P3 to a smaller value and changes the fourth threshold P4 to a larger value. As a result, in the charging / discharging system A1, for example, when the number of times the sequence process is restarted within the first specified period T5 is large, an increase in the number of restarts of the sequence process can be suppressed, thereby, for example, extending the lifespan of components used in the mobile body 100 and the charging / discharging system A1. Furthermore, in the charging / discharging system A1, for example, if the number of times the sequence processing is restarted within the first specified period T5 is small, the number of times the sequence processing is restarted can be increased, thereby making it possible to efficiently charge and discharge the first storage battery 101, for example.

[0065] Here, the control device 2 may change the duration of the first predetermined period and the second predetermined period so that the first predetermined period and the second predetermined period increase (become longer) when the number of times the sequence processing is restarted within the first specified period T5 is equal to or greater than the first predetermined number. In other words, when it is determined that the number of times the sequence processing is restarted within the first specified period T5 is equal to or greater than the first predetermined number, the control device 2 may change the duration of the first predetermined period and the second predetermined period so that the first predetermined period and the second predetermined period increase (become longer) than the periods at the time of determination. Furthermore, when the number of times the sequence processing is restarted within the first specified period T5 is less than the first predetermined number, the control device 2 may change the duration of the first predetermined period and the second predetermined period so that the first predetermined period and the second predetermined period decrease (become shorter). In other words, when the control device 2 determines that the number of restarts of the sequence process within the first specified period T5 is less than the first predetermined number, the control device 2 may change the first predetermined period and the second predetermined period so that the first predetermined period and the second predetermined period are shorter than the periods at the time of determination (so that the periods are shorter than the periods at the time of determination). This allows the charging / discharging system A1 to further suppress an increase in the number of restarts of the sequence process, for example, when the number of restarts of the sequence process within the first specified period T5 is large, thereby further extending the lifespan of components used in the moving body 100 and the charging / discharging system A1. Furthermore, when the number of restarts of the sequence process within the first specified period T5 is small, the charging / discharging system A1 can further increase the number of restarts of the sequence process, thereby enabling, for example, more efficient charging / discharging of the first storage battery 101.

[0066] Furthermore, the control device 2 may not restart the sequence process if the number of times the sequence process is stopped within a preset second specified period reaches a specified number. The second specified period is a period longer than the first specified period T5. The second specified period is, for example, one day. The specified number of times is, for example, greater than the first predetermined number of times. This allows the charging / discharging system A1 to suppress an increase in the number of times the sequence process is restarted in, for example, one day, thereby further extending the lifespan of the components used in the mobile object 100 and the charging / discharging system A1. The second specified period and the specified number of times are pre-stored in the memory of the control device 2. The second specified period is not limited to one day, and may be, for example, half a day or one week.

[0067] Furthermore, when the number of restarts of the sequence process within the second specified period reaches a specified number, the control device 2 may not stop the sequence process. This can prevent the number of stops of the sequence process per day from increasing in the charging / discharging system A1, for example, and further extend the lifespan of the components used in the moving body 100 and the charging / discharging system A1.

[0068] (4) Variations The control device 2 shown in FIG. 1 resumes the sequence processing if the first power value of the reverse flow power of the power grid 90 is equal to or greater than the third threshold P3 (see FIGS. 4 and 5) when the sequence processing is stopped. However, for example, the sequence processing may be resumed if the power value of the output power of the solar cell module 30 is equal to or greater than the third threshold P3. The output power of the solar cell module 30 is, for example, power output from the solar cell module 30 to one or more loads connected to the distribution board 80 via the power device 20 and the power switching unit 70. Note that the output power of the solar cell module 30 is not limited to power output from the solar cell module 30 to one or more loads, and may also be, for example, power output from the solar cell module 30 to the second storage battery 12 of the power storage device 10.

[0069] Furthermore, the control device 2 resumes the sequence processing if the first power value of the reverse flow power of the power system 90 is equal to or greater than the third threshold P3 when the sequence processing is stopped, but may also resume the sequence processing if, for example, the power value of the output power of the power device 20 is equal to or greater than the third threshold P3. The output power of the power device 20 is, for example, power output from the power device 20 to one or more loads via the power switching unit 70. Note that the output power of the power device 20 is not limited to power output from the power device 20 to one or more loads, and may also be, for example, power output from the power device 20 to the second storage battery 12 of the power storage device 10.

[0070] Furthermore, the control device 2 resumes the sequence processing if the first power value of the reverse flow power of the power system 90 is equal to or greater than the third threshold P3 when the sequence processing is stopped, but may also resume the sequence processing if, for example, the power value of the power that can be output from the second storage battery 12 is equal to or greater than the third threshold P3. Note that the "power value of the power that can be output from the second storage battery 12" may be, for example, the instantaneous value of the power value being output from the second storage battery 12, or the instantaneous value of a predetermined power value (for example, half the power value) of the power value being output from the second storage battery 12.

[0071] Furthermore, when the sequence processing is stopped, the control device 2 may resume the sequence processing, for example, if the power value of the total power of the power that can be output from the second storage battery 12 and the reverse flow power of the power grid 90 is equal to or greater than a third threshold value P3. That is, for example, when the sequence processing is resumed, the control device 2 calculates in advance the power value of the power that can be charged into the first storage battery 101 so that the charging / discharging device 1 can charge the first storage battery 101, and resumes the sequence processing if the calculated power value is equal to or greater than the third threshold value P3.

[0072] That is, when the sequence processing is stopped, the control device 2 resumes the sequence processing if the first power value of at least one of the reverse flow power of the power system 90, the output power of the solar cell module 30, the output power of the power device 20, and the power that can be output from the second storage battery 12 is equal to or greater than the third threshold value.

[0073] Furthermore, the control device 2 resumes the sequence processing if the second power value of the forward flow power of the power system 90 is equal to or less than the fourth threshold P4 when the sequence processing is stopped, but may also resume the sequence processing if, for example, the power value of the input power of the power device 20 is equal to or less than the fourth threshold P4. The input power of the power device 20 is, for example, power input to the power device 20 from the power system 90 via the power switching unit 70. Note that the input power of the power device 20 is not limited to only power input to the power device 20 from the power system 90, but may also be power input to the power device 20 from the solar cell module 30, for example.

[0074] Furthermore, the control device 2 resumes the sequence processing if the second power value of the forward flow power of the power system 90 is equal to or less than the fourth threshold P4 when the sequence processing is stopped. However, for example, the control device 2 may resume the sequence processing if the power value of the power that can be output from the second storage battery 12 is equal to or less than the fourth threshold P4 when the sequence processing is stopped. Furthermore, the control device 2 may resume the sequence processing if, for example, the power value of the total power of the power that can be output from the second storage battery 12 and the forward flow power of the power system 90 is equal to or less than the fourth threshold P4 when the sequence processing is stopped. In other words, the control device 2 may resume the sequence processing if the second power value of at least one of the forward flow power of the power system 90, the input power of the power device 20, and the power that can be output from the second storage battery 12 is equal to or less than the fourth threshold when the sequence processing is stopped.

[0075] The second threshold P2 is the same value (absolute value) as the first threshold P1, but may be a different value (absolute value). The predetermined period T2 is the same period as the predetermined period T1, but may be a different period.

[0076] The remote control 40 is configured to be able to change whether or not the first threshold value P1 and the second threshold value P2 are set, but is not limited to whether or not the first threshold value P1 and the second threshold value P2 are set. For example, the remote control 40 may be configured to be able to change whether or not the predetermined period T1, the first predetermined number of times, etc. Furthermore, the remote control 40 is configured to be able to change the values ​​of the first threshold value P1 and the second threshold value P2. For example, the remote control 40 may be configured to be able to change whether or not the first threshold value P1 and the second threshold value P2 are set.

[0077] The power generating device is a solar cell module 30, but is not limited to the solar cell module 30 and may be, for example, a fuel cell or the like.

[0078] The charging / discharging system A1 may include, for example, a power switching unit 70 and a distribution board 80. The charging / discharging system A1 includes a power device 20 and a solar cell module 30, but may not include the power device 20 and the solar cell module 30. In this case, the remote control 40 is electrically connected to the control device 2. The charging / discharging system A1 includes a remote control 40, but may not include the remote control 40. The charging / discharging system A1 includes a power storage device 10, but may not include the power storage device 10.

[0079] The charge / discharge system A1 supplies the power stored in the first storage battery 101 to the power storage device 10 and the distribution board 80, but may also supply the power to the power grid 90, for example.

[0080] The charging / discharging system A1 may further include a power converter 3, as shown in FIG. 7 , for example. The power converter 3 converts first AC power into first DC power. The power converter 3 also converts the first DC power into first AC power. In short, the power converter 3 is a bidirectional converter (bidirectional AC-DC converter). In this case, the power converter 3 is electrically connected to the charging / discharging device 1 and the first power converter 21 of the power device 20. The power converter 3 is also electrically connected to a distribution board 80 via a power switching unit 70. The power converter 3 is also electrically connected to a power system 90 via the power switching unit 70. The power converter 3 supplies the first DC power to the charging / discharging device 1. The power converter 3 also supplies the first AC power to at least one of the power device 20, the distribution board 80, and the power system 90.

[0081] The moving body 100 is not limited to an electric vehicle, but may be, for example, a plug-in hybrid vehicle, an electric motorcycle, etc. Furthermore, the moving body 100 is not limited to a vehicle.

[0082] The first embodiment and the modifications described above are merely a part of the various embodiments and modifications of the present disclosure.

[0083] (Embodiment 2) The charge / discharge system A1 according to the second embodiment differs from the charge / discharge system A1 according to the first embodiment in the operation of the control device 2. Note that, in the charge / discharge system A1 according to the second embodiment, the same components as those in the charge / discharge system A1 according to the first embodiment (see FIGS. 1 to 6) are denoted by the same reference numerals and will not be described.

[0084] Hereinafter, a charge / discharge system A1 according to the second embodiment will be described with reference to FIG.

[0085] (1) Operation of the charging and discharging system As shown in FIG. 8 , when the state in which the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold P1 continues for a predetermined period T1, the control device 2 controls the charging / discharging device 1 to forcibly charge the first storage battery 101 so that the power value of the charging power of the first storage battery 101 becomes equal to or greater than the first threshold P1 before receiving a request to stop the sequence processing from the mobile object 100. Furthermore, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 forcibly charges the first storage battery 101 for a predetermined period T6. The predetermined period T6 is a period during which the timing of the above-mentioned measurement by the controller of the mobile object 100 can be reset. In other words, when the state in which the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold P1 continues for the predetermined period T1, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 forcibly charges the first storage battery 101 so that the timing of the above-mentioned measurement by the mobile object 100 can be reset.

[0086] Furthermore, when the state in which the power value of the discharge power of the first storage battery 101 is equal to or less than the second threshold P2 continues for a predetermined period T2, the control device 2 controls the charge / discharge device 1 to forcibly charge the first storage battery 101 so that the power value of the discharge power of the first storage battery 101 becomes equal to or greater than the first threshold P1 before receiving a request to stop the sequence process from the mobile object 100. Furthermore, the control device 2 controls the charge / discharge device 1 to forcibly charge the first storage battery 101 for a predetermined period T7. The predetermined period T7 is a period during which the timing of the above-mentioned measurement interval by the controller of the mobile object 100 can be reset. The predetermined period T7 is, for example, the same period as the predetermined period T6. That is, when the state in which the power value of the discharge power of the first storage battery 101 is equal to or less than the second threshold P2 continues for a predetermined period T2, the control device 2 controls the charge / discharge device 1 to forcibly charge the first storage battery 101 so that the timing of the above-mentioned measurement interval by the mobile object 100 can be reset. The predetermined period T7 is the same period as the predetermined period T6, but may be a period different from the predetermined period T6.

Time t29 in FIG. 8 represents the time when the transfer of power between the mobile object 100 and the charging / discharging device 1 is permitted. Time t30 in FIG. 8 represents the time when the power value of the charging power of the first storage battery 101 becomes equal to the first threshold value P1. Time t31 in FIG. 8 represents the time when the charging / discharging device 1 starts charging the first storage battery 101 after the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold value P1 for a predetermined period T1. Time t32 in FIG. 8 represents the time when the mobile object 100 transmits a stop request signal to the control device 2 after the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold value P1 for the first period. Time t33 in FIG. 8 represents the time when the control device 2 stops the sequence processing due to, for example, a user's operation of the remote control 40. Time t34 in FIG. 8 represents the time when the control device 2 resumes the sequence processing. Time point t35 in Fig. 8 represents the time point when the power value of the discharged power of the first storage battery 101 is equal to or less than the second threshold P2. Time point t36 in Fig. 8 represents the time point when the state in which the power value of the discharged power of the first storage battery 101 is equal to or less than the second threshold P2 continues for a predetermined period T2, and the charging / discharging device 1 starts charging the first storage battery 101. Time point t37 in Fig. 8 represents the time point when the mobile object 100 transmits a stop request signal to the control device 2 when the state in which the power value of the discharged power of the first storage battery 101 is equal to or less than the second threshold P2 continues for the second period.

[0088] When the power value of the charging power of the first storage battery 101 remains below the first threshold P1 for a predetermined period T1, or when the power value of the discharging power of the first storage battery 101 remains below the second threshold P2 for a predetermined period T2, the control device 2 controls the charging / discharging device 1 to forcibly charge the first storage battery 101 before receiving a request from the mobile body 100 to stop the sequence processing, so that the power value of the charging power or discharging power of the first storage battery 101 becomes above the first threshold P1, but this is not limited to this. When both states (e.g., both consecutive states) of the power value of the charging power of the first storage battery 101 being equal to or less than the first threshold P1 and the power value of the discharging power of the first storage battery 101 being equal to or less than the second threshold P2 continue for a predetermined period T1 or a predetermined period T2, the control device 2 may control the charging / discharging device 1 to forcibly charge the first storage battery 101 so that the power value of the charging power or discharging power of the first storage battery 101 becomes equal to or greater than the first threshold P1 before receiving a request from the mobile body 100 to stop the sequence processing. That is, when at least one of the states where the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold value P1 and the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold value P2 continues for the predetermined period T1 or the predetermined period T2, the control device 2 controls the charging / discharging device 1 to forcibly charge the first storage battery 101 before receiving a request to stop the sequence processing from the mobile object 100 so that the power value of the charging power or discharging power of the first storage battery 101 becomes equal to or greater than the first threshold value P1. This prevents the mobile object 100 from transmitting a stop request signal to the control device 2 in the charging / discharging system A1. In other words, in the charging / discharging system A1, for example, when the mobile object 100 is charging or discharging the first storage battery 101, the mobile object 100 will not stop the sequence processing, and it is possible to avoid a state in which the control device 2 cannot operate. Therefore, the charging / discharging system A1 can continue to operate continuously.

[0089] When the state in which the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold P1 continues for a predetermined period T1, the control device 2 may control the charging / discharging device 1 to forcibly discharge the first storage battery 101 so that the power value of the charging power of the first storage battery 101 becomes equal to or greater than the second threshold P2 before receiving a request to stop the sequence process from the mobile object 100. In this case, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 forcibly discharges the first storage battery 101 for a predetermined period T6. In other words, when the state in which the power value of the charging power of the first storage battery 101 remains equal to or less than the first threshold P1 continues for the predetermined period T1, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 forcibly discharges the first storage battery 101 so as to reset the timing of the timing interval by the mobile object 100.

[0090] Furthermore, when the state in which the power value of the discharge power of the first storage battery 101 is equal to or less than the second threshold P2 continues for a predetermined period T2, the control device 2 may control the charge / discharge device 1 to forcibly discharge the first storage battery 101 so that the power value of the discharge power of the first storage battery 101 becomes equal to or greater than the second threshold P2 before receiving a request to stop the sequence process from the mobile object 100. In this case, the control device 2 controls the charge / discharge device 1 so that the charge / discharge device 1 forcibly discharges the first storage battery 101 for a predetermined period T7. In other words, when the state in which the power value of the discharge power of the first storage battery 101 is equal to or less than the second threshold P2 continues for a predetermined period T2, the control device 2 controls the charge / discharge device 1 so that the charge / discharge device 1 forcibly discharges the first storage battery 101 so as to reset the timing of the timing interval by the mobile object 100.

[0091] When the power value of the charging power of the first storage battery 101 remains below the first threshold P1 for a predetermined period T1, or when the power value of the discharging power of the first storage battery 101 remains below the second threshold P2 for a predetermined period T2, the control device 2 controls the charging / discharging device 1 to forcibly discharge the first storage battery 101 so that the power value of the charging power or discharging power of the first storage battery 101 becomes above the second threshold P2 before receiving a request from the mobile body 100 to stop the sequence processing, but this is not limited to this. When both states (e.g., both successive states) of the power value of the charging power of the first storage battery 101 being equal to or less than the first threshold value P1 and the power value of the discharging power of the first storage battery 101 being equal to or less than the second threshold value P2 continue for a predetermined period T1 or a predetermined period T2, the control device 2 may control the charging / discharging device 1 to forcibly discharge the first storage battery 101 so that the power value of the charging power or discharging power of the first storage battery 101 becomes equal to or greater than the second threshold value P2 before receiving a request from the mobile body 100 to stop the sequence processing. In other words, when at least one of the states where the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold value P1 and the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold value P2 continues for a predetermined period T1 or a predetermined period T2, the control device 2 controls the charging / discharging device 1 to forcibly discharge the first storage battery 101 so that the power value of the charging power or discharging power of the first storage battery 101 becomes equal to or greater than the second threshold value P2 before receiving a request from the mobile body 100 to stop the sequence processing.

[0092] As described above, the control device 2 of the charging / discharging system A1 of the second embodiment is configured to perform sequence processing with the mobile object 100 and to control the charging / discharging device 1 that charges and discharges the first storage battery 101 of the mobile object 100. As described above, after the transfer of power between the mobile object 100 and the charging / discharging device 1 is permitted in the sequence processing, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 charges and discharges the first storage battery 101. Furthermore, as described above, when at least one of a state in which the power value of the charging power of the first storage battery 101 is equal to or less than the first threshold value P1 and a state in which the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold value P2 continues for a predetermined period T1 or a predetermined period T2, the control device 2 controls the charging / discharging device 1 to forcibly charge and discharge the first storage battery 101 so that the power value of the charging power or the discharging power becomes equal to or greater than the first threshold value P1 or the second threshold value P2 before receiving a request to stop the sequence processing from the mobile object 100. This allows the control device 2 to continue operating continuously, similarly to the charge / discharge system A1 of the second embodiment.

[0093] The control method of the charging / discharging system A1 of the second embodiment is a control method for controlling a charging / discharging device 1 that performs sequence processing with a mobile object 100 and charges / discharges a first storage battery 101 of the mobile object 100. The control method includes a first process and a second process. In the first process, after the transfer of power between the mobile object 100 and the charging / discharging device 1 is permitted in the sequence processing, the charging / discharging device 1 is controlled so that the charging / discharging device 1 charges / discharges the first storage battery 101. In the second process, when at least one of a state in which the power value of the charging power of the first storage battery 101 is equal to or less than a first threshold value P1 and a state in which the power value of the discharging power of the first storage battery 101 is equal to or less than a second threshold value P2 continues for a predetermined period T1 or a predetermined period T2, the charging / discharging device 1 forcibly charges / discharges the first storage battery 101 before receiving a request to stop the sequence processing from the mobile object 100, and controls the charging / discharging device 1 so that the power value of the charging power or the discharging power becomes equal to or greater than the first threshold value P1 or the second threshold value P2. That is, the above control method is a control method for realizing the charge / discharge system A1 of embodiment 2. Therefore, the above control method allows the charge / discharge system A1 to continue operating continuously, similar to the charge / discharge system A1 of embodiment 2.

[0094] The above control method is realized by one or more processors executing a program (computer program). This program is, for example, a program for causing one or more processors of the control device 2 to execute the above control method. Therefore, according to the above program, like the above control method, the charging / discharging system A1 can continue to operate continuously.

[0095] Here, it is preferable that the control device 2 stop the sequence processing when the number of times the charging / discharging device 1 forcibly charges the first storage battery 101 reaches a predetermined number (second predetermined number). The control device 2 may stop the sequence processing not only when the number of times the charging / discharging device 1 forcibly charges the first storage battery 101 reaches the second predetermined number, but also, for example, when the charging / discharging device 1 forcibly charges the first storage battery 101 the second predetermined number of times within a preset third specified period. In short, the control device 2 may stop the sequence processing when the number of times the charging / discharging device 1 forcibly charges the first storage battery 101 reaches the second predetermined number of times, or when the charging / discharging device 1 forcibly charges the first storage battery 101 the second predetermined number of times within a preset third specified period.

[0096] Furthermore, the control device 2 may stop the sequence processing when the number of times the charging / discharging device 1 forcibly discharges the first storage battery 101 reaches a second predetermined number. The control device 2 may stop the sequence processing not only when the number of times the charging / discharging device 1 forcibly discharges the first storage battery 101 reaches the second predetermined number, but also, for example, when the charging / discharging device 1 forcibly discharges the first storage battery 101 the second predetermined number of times within a preset third specified period. In short, the control device 2 may stop the sequence processing when the number of times the charging / discharging device 1 forcibly discharges the first storage battery 101 reaches the second predetermined number of times, or when the charging / discharging device 1 forcibly discharges the first storage battery 101 the second predetermined number of times within a preset third specified period.

[0097] That is, even if the charging / discharging device 1 forcibly charges / discharges the first storage battery 101 and continues the sequence processing performed between the charging / discharging device 1 and the mobile object 100, if the charging efficiency and discharging efficiency of the first storage battery 101 are poor, the power consumption of the mobile object 100 will increase, and the control device 2 will stop the sequence processing. This allows the charging / discharging system A1 to reduce the power consumption of the mobile object 100.

[0098] (2) Variations As a modification of the second embodiment, the same modifications as those of the charge / discharge system A1 according to the modification of the first embodiment are possible. Therefore, the charge / discharge system A1 according to the modification of the second embodiment also achieves the same effects as those of the charge / discharge system A1 according to the second embodiment.

[0100] Furthermore, the charging / discharging system according to one embodiment of the present disclosure does not necessarily have to be integrated into a single housing. For example, the components of the charging / discharging system may be integrated and distributed in multiple housings.

The control device (2) sets the predetermined period (T1; T2) to a period shorter than the period.
