DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. In the drawings, the same reference numerals are used to designate the same or similar parts, and redundant explanations may be omitted.

[0011] (Overview of management system 100) 1 shows a schematic diagram of an example of the system configuration of a management system 100. In this embodiment, the management system 100 manages one or more (sometimes referred to as one or more) mobile batteries 20. The management system 100 may also manage one or more battery exchangers 120 configured to allow at least some of the multiple mobile batteries 20 to be detachable (sometimes referred to as freely detachable or easily detachable). Each of the one or more battery exchangers 120 is configured to be able to store, for example, one or more mobile batteries 20.

[0012] As described above, according to this embodiment, the mobile battery 20 is configured to be attachable to and detachable from other devices. For example, the mobile battery 20 is configured to be freely attachable to and detachable from other devices. For example, the mobile battery 20 is configured to be easily attachable to and detachable from other devices.

[0013] In one embodiment, the mobile battery 20 is configured so that even a general user who has less knowledge about maintenance than a maintenance technician who maintains the equipment to which the mobile battery 20 is attached can freely attach and detach the mobile battery 20 to the above-mentioned equipment. The mobile battery 20 is configured so that, for example, a general user can freely attach and detach the mobile battery 20 to the above-mentioned equipment without using a separate or special tool. The mobile battery 20 is configured so that a general user can freely attach and detach the mobile battery 20 to the above-mentioned equipment using a tool installed on the mobile battery 20 or the above-mentioned equipment.

[0014] In another embodiment, the mobile battery 20 is configured so that the integrity of the mobile battery 20 as a unit is not significantly impaired when the mobile battery 20 is attached to or detached from the above-mentioned device. As a result, even if a general user or a maintenance technician needs to disassemble the mobile battery 20 when removing the mobile battery 20 from the above-mentioned device, the general user or the maintenance technician can easily remove the mobile battery 20 from the above-mentioned device. Even if a general user or a maintenance technician needs to assemble the mobile battery 20 when attaching the mobile battery 20 to the above-mentioned device, the general user or the maintenance technician can easily attach the mobile battery 20 to the above-mentioned device.

[0015] For the purpose of simplifying the explanation, in this embodiment, an example of the management system 100 will be explained using as an example a case where the management system 100 provides a sharing service of the mobile battery 20 to users 40 of electric motorcycles 30. An overview of the sharing service of the mobile battery 20 will be described later.

[0016] In this embodiment, the electric motorcycle 30 is a three-wheeled motorcycle (sometimes called a rickshaw or tuk-tuk, etc.) for transportation services, and can carry luggage, passengers, etc. in addition to the operator. Examples of users 40 of the electric motorcycle 30 include the operator or passenger of the electric motorcycle 30 (sometimes called the user of the electric motorcycle 30), the owner of the electric motorcycle 30, and the manager of the electric motorcycle 30 (sometimes called the user of the electric motorcycle 30, etc.). The user 40 may be a natural person, a corporation, or an organization. The user 40 may be a manager or officer of a corporation or organization, or an employee or staff member of a corporation or organization.

[0017] In a sharing service for the mobile battery 20, the factors considered in determining the price of the service are not particularly limited. In one embodiment, the price of the sharing service is determined according to the number of times the mobile battery 20 is replaced. In another embodiment, the price of the sharing service is determined according to the degree of deterioration of the mobile battery 20 due to the user 40's use of the mobile battery 20. In another embodiment, the price of the sharing service is determined according to the amount of power used by the user 40. In another embodiment, the price of the sharing service is determined based on a combination of the above factors considered.

[0018] (Overview of management system 100) In this embodiment, the management system 100 includes one or more (sometimes simply referred to as one or more) battery exchangers 120 and a management server 140. In this embodiment, the battery exchanger 120 includes a power distribution unit 122, a battery storage unit 123, a control unit 124, a communication unit 125, an information providing unit 126, a power wiring 132, and a communication wiring 134.

[0019] According to the embodiment described in connection with FIG. 1 , the control unit 124, the communication unit 125, and the information providing unit 126 are implemented in a single housing or on a single circuit board (indicated by dotted lines in the figure). However, the battery exchange machine 120 is not limited to this embodiment. In other embodiments, the control unit 124, the communication unit 125, and the information providing unit 126 may be implemented in multiple housings or on multiple circuit boards. For example, at least two of the control unit 124, the communication unit 125, and the information providing unit 126 may be implemented in different housings or on different circuit boards.

[0020] In this embodiment, each unit of the management system 100 operates by consuming power received from the power grid 12. Each unit of the management system 100 may send and receive information to and from each other via a communication network 14.

[0021] For example, when power is normally supplied from the power system 12 to the battery exchange machine 120, the battery exchange machine 120 uses the power supplied from the power system 12 to operate the control unit 124 and charge the mobile battery 20. When an abnormality occurs in the power supply from the power system 12 to the battery exchange machine 120, the battery exchange machine 120 may operate by consuming the power stored in the mobile battery 20 stored in the battery exchange machine 120. In this case, the battery exchange machine 120 may use the power supplied from the mobile battery 20 to operate the control unit 124. Furthermore, when an abnormality occurs in the power supply from the power system 12 to the battery exchange machine 120, the battery exchange machine 120 may continue charging the mobile battery 20, or may interrupt or stop charging the mobile battery 20.

[0022] (Sharing service overview) A user 40 who has subscribed to a sharing service for the mobile battery 20 accesses the management system 100 using, for example, a communication terminal 42 and requests the rental of a mobile battery 20. The user 40 may reserve the rental of a mobile battery 20 by specifying the date, time, and location at which the user wishes to rent the mobile battery 20, as well as the number of mobile batteries 20 that the user wishes to rent. The communication terminal 42 may access the management system 100 via the communication network 14, or may access the management system 100 via the battery exchange machine 120. The user 40 may also operate the battery exchange machine 120 to request the rental of a mobile battery 20.

[0023] When the request is accepted, the user 40 can remove the mobile battery 20 stored in the battery exchange machine 120 (sometimes referred to as dispensing the mobile battery 20). This allows the user 40 to exchange the mobile battery 20 attached to the electric motorcycle 30 for the mobile battery 20 stored in the battery exchange machine 120.

[0024] More specifically, the user 40 removes the mobile battery 20 that is attached to the electric motorcycle 30 from the electric motorcycle 30. The user 40 returns the mobile battery 20 that has been removed from the electric motorcycle 30 to the battery exchange machine 120. When the user 40 returns the mobile battery 20, the battery exchange machine 120 dispenses the charged mobile battery 20 that is stored in the battery exchange machine 120. The user 40 receives the charged mobile battery 20 from the battery exchange machine 120 and attaches the charged mobile battery 20 to the electric motorcycle 30. In this way, the mobile battery 20 is exchanged between the user 40 and the battery exchange machine 120.

[0025] (Outline of each part related to the management system 100) In this embodiment, the communication network 14 transmits information. The communication network 14 may be a wired communication transmission path, a wireless communication transmission path, or a combination of a wireless communication transmission path and a wired communication transmission path. The communication network 14 may include a wireless packet communication network, the Internet, a P2P network, a dedicated line, a VPN, a power line communication line, etc.

[0026] The communication network 14 may include (i) a mobile communication network such as a mobile phone network, or (ii) a wireless communication network such as a wireless MAN (e.g., WiMAX (registered trademark)), a wireless LAN (e.g., WiFi (registered trademark)), Bluetooth (registered trademark), Zigbee (registered trademark), or NFC (Near Field Communication). Wireless LAN, Bluetooth (registered trademark), Zigbee (registered trademark), and NFC may be examples of short-range wireless communication.

[0027] In this embodiment, the mobile battery 20 stores electric energy. The mobile battery 20 may be configured to be detachable from the electric motorcycle 30 (sometimes referred to as being detachable). The mobile battery 20 may be configured to be detachable from the battery exchanger 120. This allows the user 40 to exchange the mobile battery 20 attached to the electric motorcycle 30 with the mobile battery 20 housed in the battery exchanger 120.

[0028] In one embodiment, the mobile battery 20 is attached to the electric motorcycle 30 and supplies power to the electric motorcycle 30. In another embodiment, the mobile battery 20 is charged by the battery exchanger 120 while it is housed in the battery exchanger 120. In yet another embodiment, the mobile battery 20 supplies power to the battery exchanger 120 while it is housed in the battery exchanger 120. This allows the battery exchanger 120 to use some of the mobile batteries 20 housed in the battery exchanger 120 as an uninterruptible power supply (sometimes referred to as a UPS).

[0029] In this embodiment, the electric motorcycle 30 is equipped with a mobile battery 20. The electric motorcycle 30 may be equipped with a plurality of mobile batteries 20. The electric motorcycle 30 consumes power supplied from the mobile batteries 20 to run.

[0030] In this embodiment, the communication terminal 42 transmits and receives information to and from each unit of the management system 100 via the communication network 14. The communication terminal 42 may function as a user interface when the user 40 accesses the management system 100. The communication terminal 42 may be used for user authentication processing by the management system 100.

[0031] Examples of the communication terminal 42 include a personal computer and a mobile terminal. Examples of the mobile terminal include a mobile phone, a smartphone, a PDA, a tablet, a notebook computer or laptop computer, and a wearable computer.

[0032] In this embodiment, the battery exchanger 120 accommodates the mobile battery 20. The battery exchanger 120 may accommodate a plurality of mobile batteries 20. In this embodiment, the battery exchanger 120 charges each of the plurality of mobile batteries 20. The battery exchanger 120 may charge the mobile battery 20 until the charging rate or voltage of the mobile battery 20 reaches a predetermined set value.

[0033] In this embodiment, the battery exchange machine 120 makes the fully charged mobile battery 20 ready to be removed (sometimes referred to as dispensing). In response to a request from a user 40, the battery exchange machine 120 may dispense a mobile battery 20 that meets the request. The battery exchange machine 120 may acquire information indicating dispensing conditions, which are conditions related to the mobile battery 20 to be dispensed, from the management server 140, and may determine the mobile battery 20 to actually be dispensed from among the mobile batteries 20 that meet the dispensing conditions.

[0034] In this embodiment, the battery exchanger 120 may discharge at least some of the multiple mobile batteries 20. The battery exchanger 120 may operate by consuming power output by discharging the mobile batteries 20. When the battery exchanger 120 operates by consuming power output by discharging one mobile battery 20, it may stop or interrupt the charging operation of the other mobile batteries 20. Even in this case, the battery exchanger 120 may continue the dispensing operation of the mobile batteries 20.

[0035] This allows the battery exchange machine 120 to use some of the mobile batteries 20 housed in the battery exchange machine 120 as an uninterruptible power supply. According to the battery exchange machine 120 of this embodiment, for example, even if an abnormality occurs in the power supply from the power system 12 to the battery exchange machine 120, the power supply to the control unit 124 can be continued. As a result, for example, the battery exchange machine 120 can continue to dispense mobile batteries 20. Therefore, even if the battery exchange machine 120 is installed in an area where power outages occur relatively frequently, for example, an environment in which batteries can be exchanged stably can be provided.

[0036] In general, it is very difficult to predict the frequency and scale of power outages and install an uninterruptible power supply of an appropriate size. In particular, in applications such as a battery exchanger 120, the state of charge of one or more stored mobile batteries 20 varies significantly depending on the timing of the power outage. This makes it very difficult to determine the specifications of the uninterruptible power supply. Additionally, when installing uninterruptible power supply equipment, it is necessary to secure the cost and installation space. In contrast, the battery exchanger 120 according to this embodiment can solve the above-mentioned cost and installation space issues. Furthermore, by operating the battery exchanger 120, it is possible to secure mobile batteries 20 that can be used as uninterruptible power supply equipment, thereby enabling the system to respond to sudden power outages.

[0037] The types of operations that the battery exchanger 120 can perform may differ between when the battery exchanger 120 is operating on power from the power grid 12 and when the battery exchanger 120 is operating on power from the mobile battery 20 functioning as a UPS. For example, while the battery exchanger 120 is operating on power from the mobile battery 20 functioning as a UPS, the operations that can be performed by the battery exchanger 120 are limited.

[0038] The number of types of operations that can be performed while the battery exchange device 120 is operating on power from the mobile battery 20 functioning as a UPS may be fewer than the number of types of operations that can be performed while the battery exchange device 120 is operating on power from the power grid 12. For example, while the battery exchange device 120 is operating on power from the mobile battery 20 functioning as a UPS, the charging operation of the mobile battery 20 is stopped or interrupted. This allows the battery exchange device 120 to operate for a longer period of time on power from the mobile battery 20 functioning as a UPS.

[0039] In this embodiment, the power distribution unit 122 receives power supplied from the power grid 12. The power distribution unit 122 may convert the power received from the power grid 12 into DC power. The power distribution unit 122 may supply the DC power to the power wiring 132. Details of the power distribution unit 122 will be described later.

[0040] In this embodiment, the battery storage unit 123 stores one or more mobile batteries 20. The battery storage unit 123 charges the mobile batteries 20 using DC power (sometimes referred to as charging power) supplied from the power distribution unit 122. Details of the battery storage unit 123 will be described later.

[0041] In this embodiment, the control unit 124 controls the battery exchange machine 120. The control unit 124 may control the operation of each unit of the battery exchange machine 120 using DC power supplied from the power distribution unit 122. The control unit 124 may control the operation of the battery storage unit 123. In one embodiment, the control unit 124 controls the dispensing of the mobile battery 20. In another embodiment, the control unit 124 controls the return of the mobile battery 20. In yet another embodiment, the control unit 124 controls the charging and / or discharging of the mobile battery 20. The control unit 124 may operate by consuming DC power (sometimes referred to as control power) supplied from the power distribution unit 122.

[0042] In this embodiment, the communication unit 125 communicates with the outside. The communication unit 125 may communicate with an information processing device disposed outside the battery exchange machine 120. For example, the communication unit 125 transmits and receives information to and from the electric motorcycle 30. For example, the communication unit 125 transmits and receives information to and from the communication terminal 42. For example, the communication unit 125 transmits and receives information to and from the management server 140. The communication unit 125 may be compatible with multiple communication methods.

[0043] In this embodiment, the information providing unit 126 provides information to a user of the battery exchange machine 120 (for example, the above-mentioned user 40). Examples of the information providing unit 126 include a display, a projector, and a speaker. The information providing unit 126 may function as a user interface. In this case, the information providing unit 126 may not only provide information to the user of the battery exchange machine 120, but also receive input from the user of the battery exchange machine 120.

[0044] In this embodiment, the power wiring 132 is electrically connected to each unit of the battery exchange machine 120. The power wiring 132 may transmit power supplied from the power distribution unit 122 to each unit of the battery exchange machine 120. The power wiring 132 may include a high-voltage wiring and a low-voltage wiring. The power wiring 132 may also be referred to as an internal power bus. Details of the power wiring 132 will be described later.

[0045] In this embodiment, the communication wiring 134 is communicatively connected to each unit of the battery exchange machine 120. The communication wiring 134 may be a transmission path for wired communication, a transmission path for wireless communication, or a combination of a transmission path for wireless communication and a transmission path for wired communication.

[0046] In this embodiment, the management server 140 manages one or more mobile batteries 20. For example, the management server 140 manages the status of each of the one or more mobile batteries 20. The management server 140 may manage the return and payment of each of the one or more mobile batteries 20.

[0047] The management server 140 may manage one or more battery exchangers 120. The management server 140 may manage the status of each of the one or more battery exchangers 120. Examples of the status of the battery exchanger 120 include the external power supply status, the number of mobile batteries 20 that can be accepted, the number of mobile batteries 20 that can be dispensed, the presence or absence of mobile batteries 20 that can be used as uninterruptible power supplies, the number of such mobile batteries 20 or their identification information, and the charging status of the mobile batteries 20.

[0048] The management server 140 may determine dispensing conditions, which are conditions related to the mobile batteries 20 to be dispensed, for at least some of the one or more battery exchange machines 120. Examples of dispensing conditions include the priority order for dispensing each of the multiple mobile batteries 20 stored in the battery exchange machine 120, identification information of the mobile batteries 20 to be preferentially dispensed, and characteristics of the mobile batteries 20 to be preferentially dispensed.

[0049] The power grid 12 may be an example of an external power source. The mobile battery 20 may be an example of a power storage device. The management system 100 may be an example of a power device. The battery exchanger 120 may be an example of a power device. The control unit 124 may be an example of a control unit.

The return of the mobile battery 20 may be an example of receiving an item in the storage unit. The control unit 124 may be an example of a first control unit.

[0051] (An example of another embodiment) In this embodiment, the details of the management system 100 have been described using an example in which the battery exchanger 120 receives power from the power grid 12. However, the management system 100 is not limited to this embodiment. In other embodiments, the battery exchanger 120 receives power from, for example, a stationary power source. The battery exchanger 120 may receive AC power or DC power.

[0052] In this embodiment, the management system 100 has been described in detail using as an example a case where the electric motorcycle 30 consumes power supplied from the mobile battery 20. However, the device that consumes power supplied from the mobile battery 20 (sometimes referred to as a power consumption device) is not limited to the electric motorcycle 30. In other embodiments, the power consumption device may be a mobile object powered by an electric motor, or may be a stationary power storage device.

Examples of automobiles include gasoline-powered vehicles, diesel-powered vehicles, electric vehicles, fuel cell vehicles, hybrid vehicles, small commuters, and electric carts. Examples of motorcycles include motorbikes, three-wheeled bikes, and electric bicycles. Examples of ships include boats, hovercraft, jet skis, submarines, submersibles, and underwater scooters. Examples of aircraft include airplanes, airships, balloons, helicopters, and drones.

[0054] (Specific configuration of each part of the management system 100) Each unit of the management system 100 may be implemented by hardware, software, or a combination of hardware and software. At least a portion of each unit of the management system 100 may be implemented by a single server or multiple servers.

In this embodiment, the power distribution unit 122 includes a power terminal 210, an AC / DC power supply circuit 220, a control power supply circuit 230, and an interface board 240. In this embodiment, the power wiring 132 includes a high-voltage wiring 232 and a low-voltage wiring 233.

[0058] In this embodiment, the power terminal 210 is electrically connected to the power system 12. The power terminal 210 is electrically connected to an AC / DC power supply circuit 220 of the power distribution unit 122. This allows the battery exchange machine 120 to exchange power with the power system 12 via the power terminal 210.

[0059] In this embodiment, the AC / DC power supply circuit 220 is disposed on a power transmission path arranged inside the battery exchange machine 120 and converts power. The AC / DC power supply circuit 220 converts power in accordance with, for example, an instruction from the control unit 124.

[0060] More specifically, the AC / DC power supply circuit 220 is electrically connected to the power terminal 210. The AC / DC power supply circuit 220 is electrically connected to the power grid 12 via the power terminal 210. In this embodiment, the AC / DC power supply circuit 220 receives AC power from the power grid 12. The AC / DC power supply circuit 220 converts the AC power received from the power grid 12 into DC power. The AC / DC power supply circuit 220 converts the voltage of the DC power into a voltage (e.g., DC 400 V) that can be used by electrical devices (sometimes referred to as internal devices) arranged inside the battery exchange machine 120. This generates, for example, charging power. The AC / DC power supply circuit 220 outputs the converted power to the control power supply circuit 230 and the high-voltage wiring 232.

The control power supply circuit 230 converts the voltage of the DC power received from the AC / DC power supply circuit 220 into a voltage (e.g., DC 12.5 V) that can be used by the control unit 124. This generates control power. The control power supply circuit 230 outputs the converted power to the low-voltage wiring 233 and the interface board 240. This allows the control unit 124 to operate using the power converted by the control power supply circuit 230.

[0063] In this embodiment, the high-voltage wiring 232 transmits the power output by the AC / DC power supply circuit 220.

[0069] (Slot 320 Overview) In this embodiment, the slot 320 accommodates the mobile battery 20. This allows the mobile battery 20 to be stored. The slot 320 is configured to be able to charge the mobile battery 20. The slot 320 has a function (sometimes referred to as a charging function) of supplying power from the battery exchanger 120 to the mobile battery 20 electrically connected to the power connector 322 of the slot 320.

The charger 328 may control the transfer of power between the power line 132 and the mobile battery 20. Examples of control related to the transfer of power include (i) starting, interrupting, or stopping the transfer of power, (ii) the direction in which power is transferred, and (iii) the amount of power transferred. The charger 328 may send and receive information to and from the control unit 124 via the interface board 326. The charger 328 may control the transfer of power from the power line 132 to the mobile battery 20 in accordance with commands from the control unit 124.

[0074] More specifically, the charger 328 is electrically connected to the high-voltage wiring 232. The charger 328 charges the mobile battery 20 electrically connected to the power connector 322, for example, using power supplied from the high-voltage wiring 232. The charger 328 does not have to be electrically connected to the low-voltage wiring 233. The charger 328 differs from the charger 348 described below in that it is not configured to be able to output power to the low-voltage wiring 233. The charger 328 will be described in detail below.

[0075] In this embodiment, the driving unit 329 performs various operations for storing, returning, dispensing, charging, and / or discharging the mobile battery 20. The driving unit 329 may send and receive information to and from the control unit 124 via the interface board 326. The driving unit 329 may perform the various operations described above in accordance with commands from the control unit 124. The driving unit 329 may be electrically connected to the high-voltage wiring 232 and / or the low-voltage wiring 233. The driving unit 329 may perform the various operations described above using power supplied from the high-voltage wiring 232 and / or the low-voltage wiring 233.

[0076] (Slot 340 Overview) In this embodiment, the slot 340 accommodates the mobile battery 20. This allows the mobile battery 20 to be stored. In this embodiment, the slot 320 is configured to be able to charge and discharge the mobile battery 20. The slot 340 differs from the slot 320 in that it includes a charger 348 instead of the charger 328 and has the function of charging and discharging the mobile battery 20. Except for the above differences, the slot 340 may have the same configuration as the slot 320.

[0077] In this embodiment, the charger 348 supplies power from the power line 132 to the mobile battery 20 via the power connector 322. The charger 328 may supply DC power to the mobile battery 20. The charger 348 may control the transfer of power between the power line 132 and the mobile battery 20. Examples of control related to the transfer of power include (i) starting, interrupting, or stopping the transfer of power, (ii) the direction in which power is transferred, and (iii) the amount of power transferred. The charger 348 may send and receive information to and from the control unit 124 via the interface board 326. The charger 348 may control the transfer of power from the power line 132 to the mobile battery 20 in accordance with commands from the control unit 124.

[0078] More specifically, the charger 348 is electrically connected to the high-voltage wiring 232. The charger 328 charges the mobile battery 20 electrically connected to the power connector 322, for example, using power supplied from the high-voltage wiring 232.

[0079] In this embodiment, the charger 348 is electrically connected to the low-voltage wiring 233 and configured to be able to supply power from the mobile battery 20 to the low-voltage wiring 233. The charger 348 may be configured to limit the supply of power from the low-voltage wiring 233 to the mobile battery 20. For example, the charger 348 is configured to prevent power from being supplied from the low-voltage wiring 233 to the mobile battery 20.

[0080] The charger 348 is configured to supply power from the mobile battery 20 to the low-voltage wiring 233 when the voltage of the low-voltage wiring 233 becomes lower than a predetermined value (sometimes referred to as a set value). The absolute value of the difference between the set value and the normal value of the output voltage of the control power supply circuit 230 may be 1 V or less, may be less than 1 V, or may be 0.5 V or less. As a result, if an abnormality occurs in the power supply from the power system 12 to the battery exchanger 120 due to a power outage or the like, power is automatically supplied from the mobile battery 20 to the low-voltage wiring 233. Details of the charger 348 will be described later.

[0081] The power connector 322 may be an example of a second connection section or a second input / output terminal. The charger 348 may be an example of a power conversion device or a DC power conversion device. The above set value may be an example of a voltage after conversion by the second power conversion section. The normal value of the output voltage of the control power supply circuit 230 may be an example of a voltage after conversion of the third power.

[0082] The slot 320 may be an example of a storage unit. The slot 340 may be an example of a storage unit. The interface board 326 may be an example of a second control unit.

[0083] (An example of another embodiment) In this embodiment, the slot 320 has been described in detail using an example in which a single slot 320 accommodates multiple mobile batteries 20. However, the slot 320 is not limited to this embodiment. In other embodiments, when a single slot 320 accommodates multiple mobile batteries 20, the slot 320 may have power connectors 322 and communication connectors 324 corresponding to the number of mobile batteries 20 accommodated. The slot 320 may have chargers 328 corresponding to the number of mobile batteries 20 accommodated.

[0084] In this embodiment, the slot 340 has been described in detail using an example in which a single slot 340 accommodates multiple mobile batteries 20. However, the slot 340 is not limited to this embodiment. In other embodiments, when a single slot 340 accommodates multiple mobile batteries 20, the slot 340 may have power connectors 322 and communication connectors 324 corresponding to the number of mobile batteries 20 accommodated. The slot 340 may have chargers 348 corresponding to the number of mobile batteries 20 accommodated.

[0085] 4 schematically illustrates an example of the internal configuration of the charger 328. In this embodiment, the charger 328 includes a power transmission path 410, a positive terminal 412, a negative terminal 414, and a power connector 322. In this embodiment, the power transmission path 410 includes a unidirectional DC / DC converter 420. In this embodiment, the unidirectional DC / DC converter 420 includes an input positive terminal 422, an input negative terminal 424, an output positive terminal 426, and an output negative terminal 428.

In this embodiment, the negative electrode terminal 418 is electrically connected to the output-side negative electrode terminal 428 of the unidirectional DC / DC converter 420.

[0087] 5 schematically illustrates an example of the internal configuration of the charger 348. In this embodiment, the charger 348 includes a power transmission path 410, a positive terminal 412, a negative terminal 414, and a power connector 322. In this embodiment, the power transmission path 410 includes a unidirectional DC / DC converter 420. In this embodiment, the unidirectional DC / DC converter 420 includes an input positive terminal 422, an input negative terminal 424, an output positive terminal 426, and an output negative terminal 428. In this embodiment, the power connector 322 includes a positive terminal 416 and a negative terminal 418.

[0088] In this embodiment, the positive electrode terminal 412 is electrically connected to the positive wire 402 of the high-voltage wiring 232. The positive electrode terminal 412 is electrically connected to the input-side positive electrode terminal 422 of the unidirectional DC / DC converter 420. In this embodiment, the negative electrode terminal 414 is electrically connected to the negative wire 404 of the high-voltage wiring 232. The negative electrode terminal 414 is electrically connected to the input-side negative electrode terminal 424 of the unidirectional DC / DC converter 420. In this embodiment, the positive electrode terminal 416 is electrically connected to the output-side positive electrode terminal 426 of the unidirectional DC / DC converter 420. In this embodiment, the negative electrode terminal 418 is electrically connected to the output-side negative electrode terminal 428 of the unidirectional DC / DC converter 420.

[0089] In this embodiment, charger 348 includes a power transmission path 510, a positive terminal 516, and a negative terminal 518. In this embodiment, power transmission path 510 includes a unidirectional DC / DC converter 520 and a diode 540. In this embodiment, unidirectional DC / DC converter 520 includes an input positive terminal 522, an input negative terminal 524, an output positive terminal 526, and an output negative terminal 528.

[0090] In this embodiment, the power transmission path 410 electrically connects the high-voltage wiring 232 and the power connector 322. This electrically connects the power terminal 210 and / or the AC / DC power supply circuit 220 and the power connector 322. In this embodiment, the positive terminal 416 is electrically connected to a positive terminal (not shown) included in the electrode terminal 22 of the mobile battery 20. In this embodiment, the negative terminal 418 is electrically connected to a negative terminal (not shown) included in the electrode terminal 22 of the mobile battery 20.

[0091] In this embodiment, the unidirectional DC / DC converter 420 is disposed in the power transmission path 410 and converts DC power. In this embodiment, an input-side positive terminal 422 of the unidirectional DC / DC converter 420 is electrically connected to the positive terminal 412. An input-side negative terminal 424 of the unidirectional DC / DC converter 420 is electrically connected to the negative terminal 414. An output-side positive terminal 426 of the unidirectional DC / DC converter 420 is electrically connected to the positive terminal 416. An output-side negative terminal 428 of the unidirectional DC / DC converter 420 is electrically connected to the negative terminal 418.

[0092] In this embodiment, the power transmission path 510 electrically connects the low-voltage wiring 233 and the power transmission path 410. This electrically connects the control unit 124 and the power transmission path 410. Furthermore, it electrically connects the mobile battery 20 and the control unit 124. As a result, if an abnormality occurs in the power supply from the power grid 12 to the battery exchanger 120 due to a power outage or the like, power can be automatically supplied from the mobile battery 20 to the low-voltage wiring 233.

[0093] In this embodiment, the positive electrode terminal 516 is electrically connected to the positive wire 502 of the low-voltage wiring 233. The positive electrode terminal 516 is electrically connected to the output-side positive electrode terminal 526 of the unidirectional DC / DC converter 520. More specifically, the positive electrode terminal 516 is electrically connected to the output-side positive electrode terminal 526 via a diode 540.

[0094] In this embodiment, the negative terminal 518 is electrically connected to the minus wire 504 of the low-voltage wiring 233. The negative terminal 518 is electrically connected to the output-side negative terminal 528 of the unidirectional DC / DC converter 520. In other embodiments, the negative terminal 518 may be electrically connected to the output-side positive terminal 526 via a diode (not shown).

[0095] In this embodiment, the unidirectional DC / DC converter 520 is disposed in the power transmission path 510 and converts DC power. The unidirectional DC / DC converter 520 converts the voltage of DC power input to the unidirectional DC / DC converter 520 from the mobile battery 20, for example, and outputs the DC power with the converted voltage to the low-voltage wiring 233.

[0096] The unidirectional DC / DC converter 520 converts DC power in accordance with, for example, a command from the interface board 326. When the voltage of the low-voltage wiring 233 becomes lower than a predetermined set value, the unidirectional DC / DC converter 520 may convert DC power without receiving a command from the control unit 124. The absolute value of the difference between the set value and the normal value of the output voltage of the control power supply circuit 230 may be 1 V or less, may be less than 1 V, or may be 0.5 V or less.

[0097] For example, when power is normally supplied from the power grid 12 to the battery exchanger 120, the unidirectional DC / DC converter 520 controls the voltage of the DC power output to the low-voltage wiring 233 so that the voltage on the output side of the unidirectional DC / DC converter 520 (e.g., 12 V) is smaller than the voltage on the output side of the control power supply circuit 230 (e.g., 12.5 V). In this state, no current flows out from the mobile battery 20. Furthermore, since a diode 540 is arranged between the low-voltage wiring 233 and the unidirectional DC / DC converter 520, no current flows in from the low-voltage wiring 233 to the mobile battery 20.

[0098] The voltage on the output side of the unidirectional DC / DC converter 520 may be referred to as the converted voltage of the unidirectional DC / DC converter 520. The voltage on the output side of the control power supply circuit 230 (i.e., the power of the power supplied to the low-voltage wiring 233) may be referred to as the converted voltage of the control power supply circuit 230.

[0099] On the other hand, if an abnormality occurs in the power supply from the power grid 12 to the battery exchanger 120 due to a power outage or the like, the voltage of the low-voltage line 233 will be lower than the normal value (for example, 12.5 V). If the voltage value of the low-voltage line 233 is lower than the set value of the output voltage of the unidirectional DC / DC converter 520 (for example, 12 V), a current will flow from the mobile battery 20 toward the low-voltage line 233.

[0100] By operating the unidirectional DC / DC converter 520 according to the procedure described above, the mobile battery 20 used as a USP can be placed on standby in a state where it can respond immediately to any abnormality in the power supply from the power grid 12 to the battery exchanger 120. As a result, if an abnormality occurs in the power supply from the power grid 12 to the battery exchanger 120 due to a power outage or the like, power is automatically supplied from the mobile battery 20 to the low-voltage wiring 233. As a result, the control unit 124 can continue to control the battery exchanger 120.

[0101] According to this embodiment, the control power generated by the unidirectional DC / DC converter 520 is smaller than the charging power. Therefore, the capacity and size of the unidirectional DC / DC converter 520 are smaller than the capacity and size of the unidirectional DC / DC converter 420. Furthermore, according to this embodiment, the cost and size can be reduced compared to when a bidirectional DC / DC converter is used to achieve functions similar to those of the unidirectional DC / DC converter 420 and the unidirectional DC / DC converter 520.

[0102] In this embodiment, the input positive terminal 522 is electrically connected to the positive terminal 416. The input positive terminal 522 may be electrically connected to the positive terminal 416 and the output positive terminal 426. As a result, the connection point between the power transmission path 410 and the input positive terminal 522 of the unidirectional DC / DC converter 520 is disposed between the positive terminal 416 and the output positive terminal 426.

[0103] In this embodiment, the input negative terminal 524 is electrically connected to the negative terminal 418. The input negative terminal 524 may be electrically connected to the negative terminal 418 and the output negative terminal 428. As a result, the connection point between the power transmission path 410 and the input negative terminal 524 of the unidirectional DC / DC converter 520 is disposed between the negative terminal 418 and the output negative terminal 428.

[0104] In this embodiment, the output positive terminal 526 is electrically connected to the positive terminal 516. The output positive terminal 526 of the unidirectional DC / DC converter 520 is electrically connected to the positive terminal 516 via a diode 540.

[0105] In this embodiment, the output negative terminal 528 is electrically connected to the negative terminal 518. In other embodiments, the output negative terminal 528 may be electrically connected to the output negative terminal 528 via a diode (not shown).

[0106] In this embodiment, the diode 540 is arranged in the power transmission path 510. The diode 540 is arranged, for example, between the unidirectional DC / DC converter 520 and the control unit 124. The diode 540 allows a current to flow in the direction from the unidirectional DC / DC converter 520 to the control unit 124. For example, the diode 540 allows a current to flow in the direction from the unidirectional DC / DC converter 520 to the control unit 124. The diode 540 prevents a current from flowing in the direction from the control unit 124 to the unidirectional DC / DC converter 520. For example, the diode 540 does not substantially allow a current to flow in the direction from the control unit 124 to the unidirectional DC / DC converter 520.

[0107] The location of the diode 540 is not particularly limited. In one embodiment, the diode 540 is disposed between the unidirectional DC / DC converter 520 and the low-voltage wiring 233. In another embodiment, the diode 540 is disposed between the unidirectional DC / DC converter 520 and the power connector 322.

[0108] In this embodiment, one end of diode 540 is electrically connected to positive terminal 516. The other end of diode 540 is electrically connected to output positive terminal 526. In this embodiment, diode 540 allows current to flow in the direction from output positive terminal 526 to positive terminal 516. For example, diode 540 allows current to flow in the direction from output positive terminal 526 to positive terminal 516. Diode 540 prevents current from flowing in the direction from positive terminal 516 to output positive terminal 526. For example, diode 540 does not substantially allow current to flow in the direction from positive terminal 516 to output positive terminal 526.

[0109] The power transmission path 410 may be an example of a second power transmission path. The positive terminal 412 and the negative terminal 414 may be an example of a pair of first input / output terminals. The positive terminal 416 and the negative terminal 418 may be an example of a second connection portion or a pair of second input / output terminals. The input positive terminal 422 and the input negative terminal 424 may be an example of an input of a first power conversion unit. The output positive terminal 426 and the output negative terminal 428 may be an example of an output of the first power conversion unit. The power transmission path 510 may be an example of a third power transmission path. The positive terminal 516 and the negative terminal 518 may be an example of a pair of output terminals. The unidirectional DC / DC converter 520 may be an example of a second power conversion unit. The diode 540 may be an example of a unidirectional power transmission unit or a rectifier unit.

[0110] 6 schematically illustrates an example of the normal operation of battery exchange machine 120. For the purpose of simplifying the explanation, in this embodiment, the normal operation of battery exchange machine 120 will be explained using as an example a case in which battery storage unit 123 of battery exchange machine 120 includes multiple slots, including slot 620 having a configuration similar to slot 320, and slots 642 and 644 having a configuration similar to slot 340.

[0111] According to this embodiment, when an abnormality occurs in the power supply from the power grid 12 to the battery exchanger 120, the unidirectional DC / DC converter 520 in the slot 642 operates (sometimes referred to as UPS operation) so that power is supplied from the mobile battery 20 stored in the slot 642 to the low-voltage wiring 233. On the other hand, the unidirectional DC / DC converter 520 in the slot 644 is stopped.

[0112] Of multiple slots having the same configuration as slot 340, the slot that performs UPS operation is determined by control unit 124, for example, before an abnormality occurs in the power supply from power system 12 to battery exchange machine 120. Each of the multiple slots arranged in battery exchange machine 120 determines whether to perform UPS operation in accordance with an instruction from control unit 124.

[0113] When the remaining capacity or voltage of the mobile battery 20 stored in the slot performing the UPS operation becomes smaller than a predetermined value (for example, DC 36 to 60 V), the control unit 124 determines to supply power from another mobile battery 20 to the low-voltage wiring 233. The control unit 124 controls the slot storing the other mobile battery 20 to perform the UPS operation. The control unit 124 also controls the slot storing the mobile battery 20 whose remaining capacity or voltage has become smaller than a predetermined value to stop the UPS operation.

[0114] As described above, under normal circumstances, power is normally supplied from the power grid 12 to the battery exchanger 120. In this case, the voltage after conversion by the control power supply circuit 230 is a normal value, and no current flows from the mobile battery 20 to the low-voltage wiring 233 via the power transmission path 510.

[0115] According to this embodiment, charging power is supplied from the AC / DC power supply circuit 220 to the high-voltage wiring 232. The slots 620 and 644 charge the mobile batteries 20 stored therein. The slot 642 does not need to charge the mobile battery 20 stored therein.

[0116] Furthermore, according to this embodiment, DC power is supplied from the AC / DC power supply circuit 220 to the control power supply circuit 230. As a result, the control power supply circuit 230 generates control power and supplies the power to the low-voltage wiring 233.

[0117] FIG. 7 schematically illustrates an example of the operation of the battery exchange machine 120 during a power outage. During a power outage, the supply of power from the power grid 12 to the battery exchange machine 120 is interrupted. As a result, the voltage of the charging power supplied from the AC / DC power supply circuit 220 to the high-voltage wiring 232 drops. Furthermore, the converted voltage of the control power supply circuit 230 drops, and the voltage of the low-voltage wiring 233 also drops. As described above, when the voltage of the low-voltage wiring 233 falls below a predetermined set value, power is supplied to the low-voltage wiring 233 from the mobile battery 20 stored in the slot 642. This allows the control unit 124 to continue controlling the battery exchange machine 120. For example, the control unit 124 interrupts or stops the charging operations in the slots 620 and 644.

[0118] Thereafter, when power is normally supplied from the power system 12 to the battery exchange machine 120, the control unit 124 resumes the charging operation, for example, in the slots 620 and 644. This returns the state of the battery exchange machine 120 to the state described in relation to FIG.

[0119] 8 schematically illustrates an example of the overall configuration of the battery exchange machine 120. In this embodiment, the battery exchange machine 120 includes a power distribution unit 122 and a battery storage unit 123. In this embodiment, the battery storage unit 123 includes a plurality of slots installed at different heights. For example, the battery storage unit 123 includes three slots 832 arranged at the highest position, three slots 834 arranged at a lower position than the slots 832, three slots 836 arranged at a lower position than the slots 832 and 834, and three slots 838 arranged at the lowest position.

[0120] According to this embodiment, two or more of the multiple slots have a configuration similar to slot 340. For example, the slots having a configuration similar to slot 340 are installed at a relatively low position. On the other hand, the slots having a configuration similar to slot 320 are installed at a relatively high position. The proportion of slots having a configuration similar to slot 340 among the multiple slots installed at a first height may be greater than the proportion of slots having a configuration similar to slot 340 among the multiple slots installed at a second height higher than the first height. For example, slot 832, slot 834, and slot 836 have a configuration similar to slot 320, and slot 838 has a configuration similar to slot 340.

[0121] 9 schematically shows an example of the internal configuration of the interface board 326. In this embodiment, the interface board 326 includes a communication control unit 912, a drive control unit 914, and a setting storage unit 920. In this embodiment, the setting storage unit 920 includes a DIP switch 922.

[0122] The communication control unit 912 controls communication between the slot (for example, slot 320 or slot 340) in which the interface board 326 is arranged and the control unit 124. The communication control unit 912 and the control unit 124 transmit and receive, for example, various data and / or commands related to the slot in which the interface board 326 is arranged. The communication control unit 912 and the control unit 124 may transmit and receive the above data and / or commands in association with identification information for identifying each of the multiple slots included in the battery receptacle 123. Details of the above identification information will be described later.

[0123] The drive control unit 914 controls the operation of the drive unit 329. The drive control unit 914 controls the operation of the drive unit 329 in accordance with, for example, an instruction from the control unit 124.

[0124] The setting storage unit 920 stores various settings related to control by the communication control unit 912 and the drive control unit 914. The DIP switch 922 includes n switches (not shown) that can be positioned in m different positions. This allows the DIP switch 922 to switch between m to the power of n states (sometimes referred to as switching states). For example, each switch can be positioned in two positions: a 0 position and a 1 position. The switching states are operated so that each slot has a unique or specific switching state that does not overlap among multiple slots. This allows the switching states of the DIP switch 922 to be used to identify each of multiple slots.

[0125] Information indicating the positions of the n switches of the DIP switch 922 (sometimes referred to as the setting values ​​of the DIP switch 922) is used, for example, for settings related to communication between the communication control unit 912 and the control unit 124. The setting values ​​of the DIP switch 922 indicate the switching state of the DIP switch 922.

[0126] For example, at least one of the communication control unit 912 and the control unit 124 generates data identification information indicating that the data (including commands and requests) is intended for each slot as a source or destination, based on a basic ID assigned to each slot or each interface board and information indicating the switching state of a DIP switch 922 arranged on each interface board. This allows the data to be accurately transmitted and received between the communication control unit 912 and the control unit 124, even when the communication control unit 912 and the control unit 124 transmit and receive data and / or commands using a communication method in which multiple devices share a single transmission path, such as a controller area network (CAN).

[0127] For example, the communication control unit 912 reads information indicating the switching state of the DIP switch 922 from the DIP switch 922. The communication control unit 912 changes the ID of the CAN communication in accordance with the switching state of the DIP switch 922. Specifically, the communication control unit 912 changes the ID of the CAN communication for the basic ID data handled on each interface board in accordance with the setting value of the DIP switch 922. The communication control unit 912 may change the ID of the CAN communication based on the setting value of the DIP switch 922 by referring to a predetermined data table. The communication control unit 912 may send data to the control unit 124 using the changed ID.

[0128] This allows the communication control unit 912 to transmit data obtained from each of the multiple slots onto a single CAN bus shared by the multiple slots using unique IDs, allowing the control unit 124 to appropriately monitor the status of each slot and appropriately control each slot.

[0129] The communication control unit 912 may be an example of a second control unit. The drive control unit 914 may be an example of a second control unit. The DIP switch 922 may be an example of a switching unit. Each of the n switches included in the DIP switch 922 may be an example of a first operator. The basic ID may be an example of first identification information, and the data identification information may be an example of second identification information.

[0130] 10 and 11 , an example of identification information used by the control unit 124 to identify each of the multiple slots included in the battery housing unit 123 will be described. In this embodiment, details of the above identification information will be described using an example in which the interface board 326 arranged in each of the multiple slots included in the battery housing unit 123 includes a DIP switch 922. According to this embodiment, details of the above identification information will be described using an example in which the DIP switch 922 includes four switches that can be positioned at two positions, a 0 position and a 1 position.

[0131] Fig. 10 schematically shows an example of a data table 1000 in which the position of each switch is associated with the numbers of each of the 12 slots included in the battery exchange machine 120 described in relation to Fig. 8. As shown in Fig. 10, the data table 1000 stores information indicating the correspondence between slot addresses 1022, which are combinations of the positions of each switch, and slot numbers 1024 in which each switch is arranged. Fig. 11 schematically shows an example of a data table 1100 in which a basic ID 1122 handled by each slot, a slot number 1124, and an ID 1126 for CAN communication are associated with each other.

[0132] 10, the communication control unit 912 can read information indicating the switching state of the DIP switch 922 from the DIP switch 922, and can acquire the slot number associated with the slot address indicated by the switching state by referring to a data table 1000. As shown in Fig. 11, the communication control unit 912 can acquire the ID for CAN communication associated with the basic ID and the slot number by referring to a data table 1100. This allows the communication control unit 912 to transmit data obtained from each of the multiple slots onto a single CAN bus shared by the multiple slots, using unique IDs.

[0135] In another embodiment, the power adapter 1220 and the main body 1240 are fixed or physically coupled to each other. Even in this case, the main body 1240 may be configured to be able to mount multiple types of power adapters 1220.

[0179] 18 shows an example of a computer 3000 in which aspects of the present invention may be embodied in whole or in part. At least a part of the management system 100 may be realized by the computer 3000. For example, the control unit 124 or a part thereof may be realized by the computer 3000. The management server 140 or a part thereof may be realized by the computer 3000.

[0180] A program installed on the computer 3000 can cause the computer 3000 to function as or perform operations associated with an apparatus according to an embodiment of the present invention or one or more "parts" of the apparatus, and / or to perform a process or steps of the process according to an embodiment of the present invention. Such a program can be executed by the CPU 3012 to cause the computer 3000 to perform specific operations associated with some or all of the blocks of the flowcharts and block diagrams described herein.

[0181] A computer 3000 according to this embodiment includes a CPU 3012, a RAM 3014, a GPU 3016, and a display device 3018, which are interconnected by a host controller 3010. The computer 3000 also includes input / output units such as a communication interface 3022, a hard disk drive 3024, a DVD-ROM drive 3026, and an IC card drive, which are connected to the host controller 3010 via an input / output controller 3020. The computer also includes legacy input / output units such as a ROM 3030 and a keyboard 3042, which are connected to the input / output controller 3020 via an input / output chip 3040.

[0182] The CPU 3012 operates according to programs stored in the ROM 3030 and RAM 3014, thereby controlling each unit. The GPU 3016 acquires image data generated by the CPU 3012 into a frame buffer or the like provided in the RAM 3014 or into the GPU 3016 itself, and causes the image data to be displayed on the display device 3018.

[0183] The communication interface 3022 communicates with other electronic devices via a network. The hard disk drive 3024 stores programs and data used by the CPU 3012 in the computer 3000. The DVD-ROM drive 3026 reads programs or data from the DVD-ROM 3001 and provides the programs or data to the hard disk drive 3024 via the RAM 3014. The IC card drive reads programs and data from an IC card and / or writes programs and data to an IC card.

[0184] The ROM 3030 stores therein a boot program or the like that is executed by the computer 3000 upon activation, and / or programs that depend on the hardware of the computer 3000. The input / output chip 3040 may also connect various input / output units to the input / output controller 3020 via a parallel port, a serial port, a keyboard port, a mouse port, etc.

[0185] The programs are provided by a computer-readable storage medium such as a DVD-ROM 3001 or an IC card. The programs are read from the computer-readable storage medium, installed in the hard disk drive 3024, RAM 3014, or ROM 3030, which are also examples of computer-readable storage media, and executed by the CPU 3012. The information processing described in these programs is read by the computer 3000, and brings about cooperation between the programs and the various types of hardware resources described above. An apparatus or method may be configured by implementing operations or processing of information in accordance with the use of the computer 3000.

[0186] For example, when communication is performed between computer 3000 and an external device, CPU 3012 may execute a communication program loaded into RAM 3014 and instruct communication interface 3022 to perform communication processing based on the processing described in the communication program. Under the control of CPU 3012, communication interface 3022 reads transmission data stored in a transmission buffer area provided in RAM 3014, hard disk drive 3024, DVD-ROM 3001, or a recording medium such as an IC card, and transmits the read transmission data to the network, or writes received data received from the network to a reception buffer area or the like provided on the recording medium.

[0187] Furthermore, CPU 3012 may cause all or a necessary portion of a file or database stored on an external recording medium such as hard disk drive 3024, DVD-ROM drive 3026 (DVD-ROM 3001), IC card, etc. to be read into RAM 3014, and may perform various types of processing on the data on RAM 3014. CPU 3012 may then write back the processed data to the external recording medium.

[0188] Various types of information, such as various types of programs, data, tables, and databases, may be stored on the recording medium and subjected to information processing. The CPU 3012 may perform various types of processing on data read from the RAM 3014, including various types of operations, information processing, conditional judgment, conditional branching, unconditional branching, information search / replacement, etc., as described throughout this disclosure and specified by the instruction sequences of the programs, and write the results back to the RAM 3014. The CPU 3012 may also search for information in a file, database, etc. on the recording medium. For example, if multiple entries, each having an attribute value of a first attribute associated with an attribute value of a second attribute, are stored on the recording medium, the CPU 3012 may search for an entry whose attribute value of the first attribute matches a specified condition from among the multiple entries, read the attribute value of the second attribute stored in the entry, and thereby obtain the attribute value of the second attribute associated with the first attribute that satisfies a predetermined condition.

[0189] The above-described programs or software modules may be stored in a computer-readable storage medium on or near the computer 3000. A recording medium such as a hard disk or RAM provided in a server system connected to a dedicated communication network or the Internet can also be used as a computer-readable storage medium, thereby providing the above-described programs to the computer 3000 via the network.

[0190] Although the present invention has been described above using embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It will be apparent to those skilled in the art that various modifications and improvements can be made to the above embodiments. Furthermore, the details described for a particular embodiment can be applied to other embodiments to the extent that they are not technically inconsistent. Furthermore, each component may have the same features as other components with the same name but different reference numerals.
