DETAILED DESCRIPTION OF THE INVENTION

[0012] 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.

[0013] (Embodiment 1) A charge / discharge system A1 according to the first embodiment will be described below with reference to FIGS.

[0014] (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.

[0015] 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.

[0016] (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.

[0017] (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.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] The control device 2 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.

[0022] 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.

[0023] (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.

[0024] 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.

[0025] (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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] (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.

[0034] (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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] (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 when the period during 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 is equal to or greater than a predetermined period T1. The control device 2 also stops the sequence processing when the period during 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 is equal to or greater than a predetermined period T2. The first threshold value P1 is a positive value, for example, 1 kW. The second threshold value P2 is, for example, the same value (absolute value) as the first threshold value P1. The predetermined period T2 is, for example, the same period as the predetermined period T1.

[0039] The first threshold value P1 and the second threshold value P2 are stored in advance in the memory of the control device 2. The "power value of the charging power of the first storage battery 101" is the power value (positive value) of the power when the charging / discharging device 1 charges the first storage battery 101. The "power value of the discharging power of the first storage battery 101" is 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, 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 Figure 3, in order to make it easier to visually understand the charging and discharging states of the first storage battery 101, the first threshold value P1 is represented as a positive value and the second threshold value P2 is represented as a negative value.

[0040] 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 exchange 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 the first threshold value P1. Time t4 in FIG. 3 represents the time when the period during 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 reaches the predetermined period T1. Time t5 in FIG. 3 represents the time when the control device 2 resumes the sequence processing. Time t6 in FIG. 3 represents the time when the power value of the discharging power of the first storage battery 101 is equal to or less than the second threshold value P2. Time t7 in FIG. 3 represents the time when the period during 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 reaches the predetermined period T2.

[0041] The control device 2 of the charge / discharge system A1 stops the sequence processing when the period during 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 is equal to or greater than a predetermined period T1, and when the period during 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 is equal to or greater than a predetermined period T2. That is, when the power values ​​of the charging power and discharging power of the first storage battery 101 are small, the control device 2 stops the sequence processing because the charging efficiency and discharging efficiency of the first storage battery 101 deteriorate and the power consumption of the mobile object 100 increases. This makes it possible to reduce the power consumption of the mobile object 100 in the charge / discharge system A1. In particular, when the controller of the mobile object 100 executes the sequence processing with the control device 2 of the charge / discharge system A1, the power consumption of the mobile object 100 tends to increase. Furthermore, when the vehicle 100 is a vehicle model with high power consumption (for example, a vehicle model equipped with a storage battery with a battery voltage of 800 V), the power consumption tends to be significantly higher than when the vehicle 100 is a vehicle model with low power consumption (for example, a vehicle model equipped with a storage battery with a battery voltage of 450 V). For example, when the upper limit of the voltage exchanged between the vehicle 100 and the charging / discharging device 1 is 450 V, a vehicle model equipped with a storage battery with a battery voltage of 800 V will need to step down the battery output voltage (step down the battery output voltage from 800 V to 450 V), resulting in high power consumption. Therefore, by using the charging / discharging system A1, the vehicle 100 can reduce its power consumption. Furthermore, the charging / discharging system A1 can also reduce the power consumption of the charging / discharging system A1.

[0042] The control device 2 stops the sequence processing when the period during 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 is equal to or greater than a predetermined period T1, but may stop the sequence processing when both periods (e.g., the total consecutive periods) of the period during 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 the period during 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 are equal to or greater than the predetermined period T1 or the predetermined period T2. That is, the control device 2 may stop the sequence processing when at least one of the period during 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 the period during 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 is equal to or greater than the predetermined period T1 or the predetermined period T2.

[0043] 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 / 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 / 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 when at least one of the period during 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 the period during 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 is equal to or less than the predetermined period T1 or the predetermined period T2. As a result, the control device 2 can reduce the power consumption of the mobile object 100, similar to the above-described charging / discharging system A1. Furthermore, the control device 2 can also reduce the power consumption of the charging / discharging system A1, similar to the above-described charging / discharging system A1.

[0044] The control method of 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, the sequence processing is stopped when at least one of a period during 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 period during 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 is equal to or less than a predetermined period T1 or a predetermined period T2. In other words, the control method is a control method for realizing the charging / discharging system A1. Therefore, the control method can reduce the power consumption of the mobile object 100, similar to the charging / discharging system A1 described above. Furthermore, in the above control method, similar to the above-described charging / discharging system A1, the power consumption of the charging / discharging system A1 can also be reduced.

[0045] 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, it is possible to reduce the power consumption of the moving body 100, similar to the above control method. Furthermore, according to the above program, it is possible to reduce the power consumption of the charging / discharging system A1, similar to the above control method.

[0046] 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.

[0047] 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.

[0048] 1, for example, as shown in FIG. 4, when the number of stops of the sequential processing within a predetermined specified period (first specified period) T3 is equal to or greater than a first predetermined number, the control device 2 changes the first threshold value P1 (see FIG. 3) and the second threshold value P2 (see FIG. 3) so that the values ​​(absolute values) of the first threshold value P1 and the second threshold value P2 decrease (become smaller). In other words, when the control device 2 determines that the number of stops of the sequential processing within the first specified period T3 is equal to or greater than the first predetermined number, the control device 2 changes the first threshold value P1 and the second threshold value P2 so that the values ​​of the first threshold value P1 and the second threshold value P2 decrease (become smaller) than the values ​​at the time of determination. Furthermore, when the number of stops of the sequential processing within the first specified period T3 is less than the first predetermined number, the control device 2 changes the first threshold value P1 and the second threshold value P2 so that the values ​​(absolute values) of the first threshold value P1 and the second threshold value P2 increase (become larger). In other words, when the control device 2 determines that the number of times the sequential processing has stopped within the first specified period T3 is less than the first predetermined number, the control device 2 changes the first threshold value P1 and the second threshold value P2 so that the values ​​of the first threshold value P1 and the second threshold value P2 are greater than the values ​​at the time of determination (so that the values ​​are greater than the values ​​at the time of determination). In other words, when the number of times the sequential processing has stopped within the first specified period T3 is equal to or greater than the first predetermined number, the control device 2 changes the values ​​of the first threshold value P1 and the second threshold value P2 so that the number of times the sequential processing has stopped does not increase. Furthermore, when the number of times the sequential processing has stopped within the first specified period T3 is less than the first predetermined number, the control device 2 changes the values ​​of the first threshold value P1 and the second threshold value P2 so that the number of times the sequential processing has stopped increases. The first specified period T3 is, for example, half a day. The first specified period T3 and the first predetermined number are pre-stored in the memory of the control device 2. Time points t14 to t19 in FIG. 4 represent the times when the control device 2 stops the sequential processing. 4 shows the number of executions and stops of the sequence process in half a day, and represents a case where the sequence process is executed seven times. The first specified period T3 is not limited to half a day, and may be, for example, one day.

[0049] For example, when the first predetermined number of times is set to six, the control device 2, as shown in FIG. 4, changes the first threshold value P1 and the second threshold value P2 so that the values ​​of the first threshold value P1 and the second threshold value P2 become smaller when the number of times the sequence processing is stopped within the first specified period T3 is six. Furthermore, when the number of times the sequence processing is stopped within the first specified period T3 is four, the control device 2 changes the first threshold value P1 and the second threshold value P2 so that the values ​​of the first threshold value P1 and the second threshold value P2 become larger. This prevents the number of times the sequence processing is stopped within the first specified period T3 from increasing. This allows, for example, the lifespan of components (e.g., contact devices) used in the mobile object 100 and the charge / discharge system A1 to be extended. In particular, contact devices such as relays in the mobile object 100 are consumable parts with a finite number of times the contacts can be turned on and off (used). Therefore, for example, it is not desirable to repeatedly stop and restart the sequence processing. Therefore, in the charging / discharging system A1, for example, if the number of times the sequence process is stopped within the first specified period T3 is large, the values ​​of the first threshold value P1 and the second threshold value P2 are changed so as not to increase the number of times the sequence process is stopped, so as to prevent the lifespan of the parts used in the moving body 100 from reaching the end of their lives early. Also, in the charging / discharging system A1, for example, if the number of times the sequence process is stopped within the first specified period T3 is small, the number of times the sequence process is stopped can be increased, so that the power consumption of the moving body 100 can be further reduced.

[0050] Here, when the number of times the sequence processing is stopped within the first specified period T3 is equal to or greater than the first predetermined number, the control device 2 may change the duration of the predetermined period T1 (see FIG. 3) and the predetermined period T2 (see FIG. 3) so that they increase (become longer). In other words, when the control device 2 determines that the number of times the sequence processing is stopped within the first specified period T3 is equal to or greater than the first predetermined number, the control device 2 may change the duration of the predetermined period T1 and the predetermined period T2 so that they increase (become longer) than the periods at the time of determination. Furthermore, when the number of times the sequence processing is stopped within the first specified period T3 is less than the first predetermined number, the control device 2 may change the duration of the predetermined period T1 and the predetermined period T2 so that they decrease (become shorter). In other words, when the control device 2 determines that the number of times the sequence process is stopped within the first specified period T3 is less than the first predetermined number, the control device 2 may change the duration of the predetermined period T1 and the predetermined period T2 so that the durations are shorter than those at the time of determination (so that the durations are shorter than those at the time of determination). In this way, in the charge / discharge system A1, for example, when the number of times the sequence process is stopped within the first specified period T3 is large, the increase in the number of times the sequence process is stopped can be further suppressed, thereby further extending the lifespan of the components used in the mobile object 100 and the charge / discharge system A1. Furthermore, in the charge / discharge system A1, for example, when the number of times the sequence process is stopped within the first specified period T3 is small, the number of times the sequence process is stopped can be further increased, thereby further reducing the power consumption of the mobile object 100.

[0051] The control device 2 shown in FIG. 1 preferably stops the sequence processing when the charging / discharging device 1 is not charging or discharging the first storage battery 101. In other words, the control device 2 preferably stops the sequence processing when the charging / discharging device 1 is not charging or discharging the first storage battery 101. This allows the charging / discharging system A1 to further reduce power consumption of the mobile object 100. Furthermore, it is more preferable for the control device 2 to stop the sequence processing when a state in which the charging / discharging device 1 is not charging or discharging the first storage battery 101 continues for a predetermined period of time (e.g., five minutes). This allows the charging / discharging system A1 to accurately detect a period in which the charging / discharging device 1 is not charging or discharging the first storage battery 101, thereby preventing, for example, erroneous stopping of the sequence processing.

[0052] Note that "when the charging / discharging device 1 is not in a period in which it charges or discharges the first storage battery 101" means, for example, a period other than a period in which the charging / discharging device 1 charges or discharges the first storage battery 101 (for example, a standby period of the charging / discharging device 1). Also, "a state in which the charging / discharging device 1 is not in a period in which it charges or discharges the first storage battery 101" means, for example, a state in which the charging / discharging device 1 is not charging or discharging the first storage battery 101 (in other words, the charging / discharging device 1 is in a standby state).

[0053] It is preferable that the control device 2 stops the sequence processing when the first storage battery 101 is fully charged after being charged by the charging / discharging device 1. More specifically, it is preferable that the control device 2 stops the sequence processing when the first storage battery 101 is fully charged in a mode in which the charging / discharging device 1 only performs charging (one of the operation modes described below). This allows the charging / discharging system A1 to further reduce power consumption of the mobile object 100. Furthermore, it is also preferable that the charging / discharging system A1 reduce deterioration of the first storage battery 101 of the mobile object 100. It is also more preferable that the control device 2 stops the sequence processing when the first storage battery 101 is charged by the charging / discharging device 1 and the first storage battery 101 remains fully charged for the certain period of time. This allows the charging / discharging system A1 to accurately detect whether the first storage battery 101 is fully charged, thereby preventing, for example, erroneous stopping of the sequence processing.

[0054] Note that "a state in which the first storage battery 101 is fully charged" refers to, for example, a state in which the first storage battery 101 cannot be charged, and includes, for example, a state in which the state of charge (SOC) of the first storage battery 101 is 100%. However, "a state in which the first storage battery 101 is fully charged" is not limited to a state in which the state of charge of the first storage battery 101 is 100%, and also includes, for example, a state in which the state of charge of the first storage battery 101 is 80% or higher, and also includes a case in which the state of charge of the first storage battery 101 is set to a state in which charging is not possible in a specific time period due to, for example, a setting of the state of charge of the first storage battery 101 by a user operation (for example, a user operation of the remote control 40).

[0055] Furthermore, it is preferable that the control device 2 stop the sequence processing when the first storage battery 101 is discharged by the charging / discharging device 1 and the first storage battery 101 is at its lower discharge limit. More specifically, it is preferable that the control device 2 stop the sequence processing when the first storage battery 101 is at its lower discharge limit in a mode in which the charging / discharging device 1 only performs discharge (one of the operation modes described below). This allows the charging / discharging system A1 to further reduce the power consumption of the mobile object 100. It is also more preferable that the control device 2 stop the sequence processing when the first storage battery 101 is discharged by the charging / discharging device 1 and the state in which the first storage battery 101 is at its lower discharge limit continues for the certain period of time. This allows the charging / discharging system A1 to accurately detect the state in which the first storage battery 101 is at its lower discharge limit, thereby preventing, for example, erroneous stopping of the sequence processing. Note that the "state in which the first storage battery 101 is at the lower discharge limit" refers to, for example, a state in which the first storage battery 101 cannot discharge, and includes, for example, a state in which the charge rate of the first storage battery 101 is 20% or less.

[0056] The control device 2 preferably stops the sequence processing when the first storage battery 101 or the second storage battery 12 is fully charged. More specifically, when power is exchanged between the first storage battery 101 and the second storage battery 12, the control device 2 preferably stops the sequence processing when the first storage battery 101 or the second storage battery 12 is fully charged. Furthermore, the control device 2 preferably stops the sequence processing when the first storage battery 101 or the second storage battery 12 is at its lower discharge limit. More specifically, when power is exchanged between the first storage battery 101 and the second storage battery 12, the control device 2 preferably stops the sequence processing when the first storage battery 101 or the second storage battery 12 is at its lower discharge limit. This allows the charging / discharging system A1 to further reduce the power consumption of the mobile object 100. Furthermore, the control device 2 more preferably stops the sequence processing when the first storage battery 101 or the second storage battery 12 remains fully charged for the certain period of time. Furthermore, it is more preferable that the control device 2 stops the sequence process when the state in which the first storage battery 101 or the second storage battery 12 is at the lower discharge limit continues for the above-mentioned certain time period. This allows the charge / discharge system A1 to accurately detect the state in which the first storage battery 101 or the second storage battery 12 is at the full charge or lower discharge limit, thereby preventing, for example, erroneous stopping of the sequence process.

[0057] (4) Variations 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] The charging / discharging system A1 may further include a power converter 3, as shown in FIG. 5 , 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.

[0063] 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.

[0064] The first embodiment and the modifications described above are merely a part of the various embodiments and modifications of the present disclosure.

[0065] (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 4) are denoted by the same reference numerals and will not be described.

[0066] The charge / discharge system A1 according to the second embodiment will be described below with reference to FIGS.

[0067] (1) Operation of the charging / discharging system 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 backward flow power of the power grid 90, is equal to or greater than a third threshold P3 (see FIGS. 6 and 7). 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. 6 and 7). The fourth threshold P4 is a value smaller than the third threshold P3. The third threshold P3 is set to be larger than the first threshold P1 (see FIG. 3). The fourth threshold P4 is set to be smaller than the second threshold P2 (see FIG. 3).

[0068] The third threshold value P3 and the fourth threshold value P4 are stored in advance in the memory of the control device 2. "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. Furthermore, "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.

[0069] 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 further 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, for example, efficiently charge and discharge the first storage battery 101. That is, the charging / discharging system A1 can operate efficiently and further reduce power consumption.

[0070] Note that "surplus power" refers to, for example, 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). Also, "power shortage" refers to, for example, the power remaining after subtracting the power generated by the power generation device from the power consumption of one or more loads. Also, time t8 in FIG. 6 represents the time when the first power value of the reverse flow power of the power grid 90 reaches the third threshold P3. Time t9 in FIG. 6 represents the time when the second power value of the forward flow power of the power grid 90 reaches the fourth threshold P4. Time t10 in FIG. 7 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 t11 in FIG. 7 represents the time when the control device 2 stops the sequence processing due to, for example, a user's operation on the remote control 40. 7 indicates the time when the second power value of the forward flow power of the power grid 90 reaches the fourth threshold P4 and the control device 2 resumes the sequence processing. Time t13 in Fig. 7 indicates the time when the control device 2 stops the sequence processing in response to, for example, a user's operation on the remote control 40.

[0071] 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 a 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 a 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 may be a period different 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, for example, charge / discharge the first storage battery 101 more efficiently. That is, the charging / discharging system A1 can operate more efficiently, further reducing power consumption.

[0072] The first and second predetermined periods are stored in advance 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 Fig. 7, the control device 2 resumes the sequence processing when the power value of the backward flow power of the power grid 90 becomes equal to or greater than the third threshold value P3 and when the power value of the forward flow power of the power grid 90 becomes equal to or less than the fourth threshold value P4. Therefore, the first and second predetermined periods are not shown in Fig. 7.

[0073] 8, for example, when the number of restarts of the sequence processing within the first specified period T3 is equal to or greater than a second predetermined number of times, the control device 2 changes the third threshold value P3 (see FIGS. 6 and 7) so as to increase the third threshold value P3 (to a larger value), and changes the fourth threshold value P4 (see FIGS. 6 and 7) so as to decrease the fourth threshold value P4 (to a smaller value). In other words, when it is determined that the number of restarts of the sequence processing within the first specified period T3 is equal to or greater than the second predetermined number of times, the control device 2 changes the third threshold value P3 so as to increase the third threshold value P3 from the value at the time of determination (to a value larger than the value at the time of determination), and changes the fourth threshold value P4 so as to decrease the fourth threshold value P4 from the value at the time of determination (to a value smaller than the value at the time of determination). Furthermore, when the number of restarts of the sequential processing within the first specified period T3 is less than the second predetermined number, the control device 2 changes the third threshold P3 to decrease the third threshold P3 and changes the fourth threshold P4 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 T3 is less than the second predetermined number, the control device 2 changes the third threshold P3 to decrease the third threshold P3 from its value at the time of determination and changes the fourth threshold P4 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 T3 is equal to or greater than the second predetermined number, the control device 2 changes the values ​​of the third threshold P3 and the fourth threshold P4 so that the number of restarts of the sequential processing does not increase. Furthermore, when the number of restarts of the sequential processing within the first specified period T3 is less than the second predetermined number, the control device 2 changes the values ​​of the third threshold P3 and the fourth threshold P4 so that the number of restarts of the sequential processing increases. The second predetermined number of times is stored in advance in the memory of the control device 2. Time points t20 to t25 in Fig. 8 represent the times when the control device 2 resumes the sequence processing. The example in Fig. 8 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.

[0074] 8, when the second predetermined number of times is set to six, if the number of times the sequence process is restarted within the first specified period T3 is six, the control device 2 changes the third threshold P3 to a larger value and changes the fourth threshold P4 to a smaller value. Furthermore, if the number of times the sequence process is restarted within the first specified period T3 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, if the number of times the sequence process is restarted within the first specified period T3 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 T3 is small, the number of times the sequence processing is restarted can be increased, thereby making it possible to charge and discharge the first storage battery 101 efficiently, for example.

[0075] 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 T3 is equal to or greater than the second predetermined number. In other words, when it is determined that the number of times the sequence processing is restarted within the first specified period T3 is equal to or greater than the second 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 T3 is less than the second 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 T3 is less than the second specified number of times, the control device 2 may change the first specified period and the second specified period so that the first specified period and the second specified 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 T3 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 T3 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.

[0076] The control device 2 is configured to control the charging / discharging device 1 based on an operation mode for determining the operation of the charging / discharging device 1. The operation modes include, for example, a mode in which the charging / discharging device 1 only charges, a mode in which the charging / discharging device 1 only discharges, and a mode in which the charging / discharging device 1 neither charges nor discharges (standby mode). The modes in which the charging / discharging device 1 only charges include, for example, a forced charging mode (hereinafter referred to as a "first operation mode") and a surplus charging mode (hereinafter referred to as a "second operation mode"). The first operation mode is, for example, an operation mode in which the first storage battery 101 is forcibly charged with power purchased from the power grid 90. The second operation mode is, for example, an operation mode in which the power of the entire charging / discharging system A1 is surplus power and the first storage battery 101 is charged with the surplus power.

[0077] When the operation mode is the first operation mode, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 charges the first storage battery 101, for example, at a preset time (for example, a charging start time). Furthermore, when the operation mode is the first operation mode, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 charges the first storage battery 101, for example, when the user operates the remote control 40 (for example, pressing a charge start button). Note that when the operation mode is the first operation mode, the control device 2 may control the charging / discharging device 1 so that the charging / discharging device 1 charges the first storage battery 101 not only when the user operates the remote control 40 (for example, pressing a charge button), but also, for example, when the user operates an operation button electrically connected to the control device 2 (for example, pressing a charge button).

[0078] Here, when the sequential process is stopped, it is preferable that the control device 2 resumes the sequential process if there is a change in the operation mode at a preset time (e.g., charging start time, etc.) (e.g., when the operation mode is changed from the first operation mode to the second operation mode). Also, when the sequential process is stopped, it is preferable that the control device 2 resumes the sequential process if there is a change in the operation mode due to a user operation (e.g., a user operation on the remote control 40) (e.g., when the operation mode is changed from the first operation mode to the second operation mode). This makes it possible for the charge / discharge system A1 to efficiently charge and discharge, for example, the first storage battery 101.

[0079] Furthermore, the control device 2 may resume the sequence processing when a certain time (e.g., 60 minutes) has elapsed since the sequence processing was stopped. This allows the charge / discharge system A1 to efficiently charge and discharge, for example, the first storage battery 101. Note that, for example, the control device 2 may change the certain time so that the certain time increases (becomes longer) when the number of times the sequence processing is stopped within the first specified period T3 is equal to or greater than a first predetermined number. In other words, when it is determined that the number of times the sequence processing is stopped within the first specified period T3 is equal to or greater than the first predetermined number, the control device 2 may change the certain time so that the certain time increases (becomes longer) than the time at the time of determination. Furthermore, for example, when the number of times the sequence processing is stopped within the first specified period T3 is less than the first predetermined number, the control device 2 may change the certain time so that the certain time decreases (becomes shorter). In other words, when the control device 2 determines that the number of times the sequence processing is stopped within the first specified period T3 is less than the first predetermined number of times, the control device 2 may change the above-mentioned fixed time so that the above-mentioned fixed time is shorter than the time at the time of determination (so that the time is shorter than the time at the time of determination).

[0080] Furthermore, the control device 2 may not restart the sequence process if the number of times the sequence process is stopped within a predetermined second specified period reaches a specified number. The second specified period is a period longer than the first specified period T3. 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.

[0081] 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.

[0082] 9, for example, the control device 2 may control the power storage device 10 so that the power storage device 10 charges and discharges the second storage battery 12 when the sequence processing is stopped. For example, the control device 2 controls the power storage device 10 so that the power storage device 10 supplies the power generated by the solar cell module 30 to the second storage battery 12 when the sequence processing is stopped. Furthermore, the control device 2 controls the power storage device 10 so that the power storage device 10 supplies the power stored in the second storage battery 12 to the distribution board 80 when the sequence processing is stopped between the charging and discharging system A1 and the mobile object 100 (when power is not exchanged with the mobile object 100), for example, so that the power generated by the solar cell module 30 is supplied to the second storage battery 12 and the power stored in the second storage battery 12 is supplied to the distribution board 80. That is, in the charging / discharging system A1, the sequence process between the charging / discharging system A1 and the moving object 100 can be stopped without wasting the power of the entire charging / discharging system A1.

[0083] Note that time point t26 in Fig. 9 represents the time point when the second storage battery 12 is fully charged and the time point when the control device 2 resumes the sequence processing. Time point t27 in Fig. 9 represents the time point when the first storage battery 101 is fully charged and the time point when the control device 2 stops the sequence processing. Time point t28 in Fig. 9 represents the time point when the second storage battery 12 reaches the lower discharge limit and the time point when the control device 2 resumes the sequence processing. Time point t28 in Fig. 9 also represents the time point when the charging / discharging device 1 starts discharging the first storage battery 101. Time point t29 in Fig. 9 represents the time point when the control device 2 stops the sequence processing.

[0084] Furthermore, the control device 2 may resume the sequential process, for example, when the second storage battery 12 is fully charged (at time t26 in the example of FIG. 9 ) when the sequential process is stopped. More specifically, the control device 2 may resume the sequential process, for example, when the power of the entire charging / discharging system A1 is surplus power and the second storage battery 12 is fully charged when the sequential process is stopped. In this case, it is preferable that the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 charges the first storage battery 101 and controls the power storage device 10 so that the power stored in the second storage battery 12 is supplied to the first storage battery 101 when the sequential process is resumed (the period from time t26 to time t27 in the example of FIG. 9 ). Specifically, for example, when the sequential process is resumed, the control device 2 controls the charging / discharging device 1 so that the charging / discharging device 1 supplies power generated by the solar cell module 30 or power (forward flow power) from the power grid 90 to the first storage battery 101. Furthermore, the control device 2 controls the power storage device 10 so that, for example, when the sequence processing is resumed, the power storage device 10 supplies the power stored in the second storage battery 12 to the first storage battery 101. As a result, in the charging / discharging system A1, the charging time of the first storage battery 101 of the mobile object 100 is shortened. That is, in the charging / discharging system A1, the execution time of the sequence processing between the mobile object 100 and the control device 2 can be shortened, thereby further reducing the power consumption of the mobile object 100. Furthermore, in the charging / discharging system A1, if the second storage battery 12 is fully charged when the sequence processing is stopped, the control device 2 resumes the sequence processing. Therefore, for example, the user does not need to operate the remote control 40 to resume the sequence processing, and the sequence processing can be resumed automatically. Therefore, in the charging / discharging system A1, the sequence processing can be frequently stopped, thereby further reducing the power consumption of the mobile object 100.

[0085] The control device 2 may resume the sequence processing not only when the second storage battery 12 is fully charged when the sequence processing is stopped, but also when the charge rate of the second storage battery 12 is a preset charge rate (e.g., 70%), for example. In short, the control device 2 may resume the sequence processing only when the second storage battery 12 is at least fully charged when the sequence processing is stopped. The preset charge rate is set, for example, by the user operating the remote control 40.

[0086] Furthermore, it is preferable that the control device 2 stop the sequence processing when, for example, the first storage battery 101 is fully charged (at time t27 in the example of FIG. 9 ) after resuming the sequence processing. It is also preferable that the control device 2 stop the sequence processing when, for example, the second storage battery 12 is at its lower discharge limit after resuming the sequence processing. This makes it possible to prevent the charge / discharge system A1 from continuing to execute the sequence processing even when, for example, the first storage battery 101 is fully charged or the second storage battery 12 is at its lower discharge limit. Therefore, it is possible to further reduce the power consumption of the mobile object 100 in the charge / discharge system A1. It is also preferable that the control device 2 stop the sequence processing when, for example, the first storage battery 101 is fully charged after resuming the sequence processing. Furthermore, the control device 2 may stop the sequence processing not only when the second storage battery 12 is at the lower discharge limit after resuming the sequence processing, but also when the charge rate of the second storage battery 12 is a preset charge rate (e.g., 30%), for example. In short, the control device 2 may stop the sequence processing when the second storage battery 12 is at least at the lower discharge limit after resuming the sequence processing.

[0087] Furthermore, the control device 2 may resume the sequential process if the second storage battery 12 is at its lower discharge limit when the sequential process is stopped (at time t28 in the example of FIG. 9). More specifically, the control device 2 may resume the sequential process if, for example, the power of the entire charging / discharging system A1 is insufficient and the second storage battery 12 is at its lower discharge limit when the sequential process is stopped. In this case, the control device 2 may, for example, control the charging / discharging device 1 so that the charging / discharging device 1 supplies the power stored in the first storage battery 101 to the second storage battery 12 when the sequential process is restarted. Furthermore, the control device 2 may, for example, control the charging / discharging device 1 so that the charging / discharging device 1 also supplies the power stored in the first storage battery 101 to the distribution board 80 when the sequential process is restarted (for example, during the period from time t28 to time t29 in the example of FIG. 9). As a result, in the charging / discharging system A1, the discharge time of the first storage battery 101 of the mobile object 100 is shortened after the sequential process is restarted. That is, in the charging / discharging system A1, the execution time of the sequence processing between the mobile object 100 and the charging / discharging system A1 can be shortened, thereby further reducing the power consumption of the mobile object 100. Furthermore, in the charging / discharging system A1, the control device 2 resumes the sequence processing if the second storage battery 12 is at the lower discharge limit when the sequence processing is stopped, so that the sequence processing can be resumed automatically without the need for the user to operate the remote control 40, for example. Therefore, in the charging / discharging system A1, the sequence processing can be frequently stopped, thereby further reducing the power consumption of the mobile object 100.

[0088] The control device 2 may resume the sequential process not only when the second storage battery 12 is at the lower discharge limit but also when the charge rate of the second storage battery 12 is a preset charge rate (e.g., 30%) when the sequential process is stopped. In short, the control device 2 may stop the sequential process if the second storage battery 12 is at least at the lower discharge limit when the sequential process is stopped. Furthermore, when the sequential process is resumed, the control device 2 causes the charging / discharging device 1 to supply the power stored in the first storage battery 101 to the second storage battery 12. Alternatively, for example, the control device 2 may control the charging / discharging device 1 so that the charging / discharging device 1 supplies the power stored in the first storage battery 101 to the distribution board 80. In other words, the control device 2 may control the charging / discharging device 1 so that the charging / discharging device 1 supplies the power stored in the first storage battery 101 to at least the second storage battery 12 when the sequential process is resumed.

[0089] Furthermore, it is preferable that the control device 2 stop the sequence processing when the second storage battery 12 is fully charged (at time t29 in the example of FIG. 9 ) after resuming the sequence processing. It is also preferable that the control device 2 stop the sequence processing when the first storage battery 101 is at its lower discharge limit after resuming the sequence processing. This makes it possible to prevent the charge / discharge system A1 from continuing to execute the sequence processing even when, for example, the second storage battery 12 is fully charged or the first storage battery 101 is at its lower discharge limit. Therefore, it is possible to further reduce the power consumption of the mobile object 100 in the charge / discharge system A1.

[0090] Note that the control device 2 may stop the sequence processing not only when the second storage battery 12 is fully charged after the sequence processing is resumed, but may also stop the sequence processing, for example, when the state of charge of the second storage battery 12 is 70%. In short, the control device 2 may stop the sequence processing only when the second storage battery 12 is at least fully charged after the sequence processing is resumed. Furthermore, the control device 2 may stop the sequence processing not only when the first storage battery 101 is at the lower discharge limit after the sequence processing is resumed, but may also stop the sequence processing, for example, when the state of charge of the first storage battery 101 is at a preset charge limit (for example, 30%). In short, the control device 2 may stop the sequence processing only when the first storage battery 101 is at least at the lower discharge limit after the sequence processing is resumed.

[0091] (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.

[0092] The control device 2 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 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.

[0093] 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.

[0094] 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.

[0095] Furthermore, when the sequential process is stopped, the control device 2 may resume the sequential process, 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 P3. That is, for example, the control device 2 calculates in advance the power value of the power that can be charged into the first storage battery 101 when the sequential process is resumed so that the charging / discharging device 1 can charge the first storage battery 101, and resumes the sequential process if the calculated power value is equal to or greater than the third threshold P3.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] The control device 2 resumes the sequence processing if the operation mode is changed at a preset time when the sequence processing is stopped, but may resume the sequence processing at a preset time regardless of the change in the operation mode, for example. Furthermore, the control device 2 resumes the sequence processing if the operation mode is changed by a user operation when the sequence processing is stopped, but may resume the sequence processing if the user operates the remote control 40 regardless of the change in the operation mode, for example.

[0100] The present disclosure is not limited to the above-described embodiments, and at least some of the configurations of the embodiments and modified examples can be combined as appropriate and applied.

[0101] 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.

[0102] (Aspect) The present specification discloses the following aspects.

[0103] A charging / discharging system (A1) according to a first aspect includes a charging / discharging device (1) that charges / discharges a storage battery (101) of a mobile object (100), and a control device (2) that performs sequence processing between the charging / discharging device (1) and the mobile object (100) and controls the charging / discharging device (1).

When the number of stops is less than the first predetermined number, the control device (2) changes the first threshold value (P1) and the second threshold value (P2) so that the first threshold value (P1) and the second threshold value (P2) increase.

A control device (2) controls the charging / discharging device (1) to perform charging / discharging between the first storage battery (101) and the second storage battery (12). The control device (2) stops sequence processing when the first storage battery (101) or the second storage battery (12) is fully charged or at a lower discharge limit.

[0147] A charge / discharge system (A1) according to a 23rd aspect is the 22nd aspect, in which, when the sequence processing is resumed, the control device (2) controls the charge / discharge device (1) so that the charge / discharge device (1) charges the first storage battery (101), and controls the storage device (10) so that the storage device (10) supplies the power stored in the second storage battery (12) to the first storage battery (101).

[0148] According to this embodiment, the charging time of the first storage battery (101) of the mobile object (100) can be shortened, and the execution time of the sequence process can be shortened, thereby further reducing the power consumption of the mobile object (100).

[0149] In the charge / discharge system (A1) according to a 24th aspect, in the 23rd aspect, the control device (2) stops the sequence processing when the first storage battery (101) is fully charged or when the second storage battery (12) is at a lower discharge limit.
