[Figure 2] FIG. 10 is a schematic block diagram illustrating an asset management system according to a second embodiment of the present disclosure. [Figure 3] Figure 2. Schematic diagram of the asset management system [Figure 4] Figure 2: Control flow chart of the asset management system DETAILED DESCRIPTION OF THE INVENTION

[0012] (Background to this disclosure) Some electronic devices, such as PCs and tablets, have short-range wireless communication capabilities. Typically, the communication unit that provides the short-range wireless communication capability is built into the device itself and can be used when the device is powered on.

[0013] On the other hand, there is also a need to be able to use short-range wireless communication functions even when an electronic device is turned off. For example, there are cases where it is necessary to use short-range wireless communication functions to determine the location of an electronic device that is turned off. However, conventional electronic devices have a problem in that the short-range wireless communication functions cannot be used when the power is off.

[0014] The present inventors have studied a battery pack, an electronic device, a communication system, and a communication method that are capable of performing short-distance communication when the power of the electronic device is turned off, and have arrived at the following invention.

[0015] An embodiment of the present disclosure will be described below with reference to the accompanying drawings. Note that the following description is merely exemplary in nature and is not intended to limit the present disclosure, its applications, or its uses. Furthermore, the drawings are schematic, and the ratios of the dimensions and the like do not necessarily correspond to reality.

[0016] It should be noted that, in this specification, terms such as "first," "second," etc. are used for descriptive purposes only and should not be understood as expressing or implying the relative importance or ranking of technical features. Features qualified as "first" and "second" expressly or imply the inclusion of one or more of such features.

[0017] (Embodiment 1) [Overall configuration] 1 is a schematic block diagram illustrating a configuration of an electronic device according to a first embodiment of the present disclosure. An electronic device 10 can detachably mount a battery pack 20, and is supplied with power from a battery 21 of the battery pack 20.

[0018] <Battery pack> The battery pack 20 is detachably mounted on the electronic device 10 and supplies power to the electronic device 10. The battery pack 20 includes a battery 21, a first communication unit 22, and a setting holding unit .

[0019] The battery 21 is configured by a secondary battery such as a lithium ion battery. The battery 21 supplies power to the electronic device 10 and also supplies power to the first communication unit 22. Note that the supply of power from the battery 21 to the first communication unit 22 is performed based on the settings set in the setting holding unit 23 when the battery pack 20 is connected to the electronic device 10.

[0020] The first communication unit 22 includes a circuit that performs short-distance wireless communication with an external device (not shown) of the electronic device 10 in accordance with a predetermined communication standard. The predetermined communication standard includes, for example, Bluetooth (registered trademark). Short-distance wireless communication means wireless communication within, for example, several meters. For example, short-distance wireless communication may be wireless communication within 50 meters, preferably wireless communication within 10 meters, and more preferably wireless communication within 5 meters. The first communication unit 22 corresponds to the "communication unit" in this disclosure.

[0021] The setting holding unit 23 holds a setting related to power supply from the battery 21 to the first communication unit 22. The setting related to power supply is a value indicating whether or not power is to be supplied from the battery 21 to the first communication unit 22 when the battery pack 20 is connected to the electronic device 10. The setting related to power is held in the setting holding unit 23, for example, as a flag indicating whether power is to be supplied (ON) or not (OFF) from the battery 21 to the first communication unit 22. The setting holding unit 23 is configured by a storage medium such as a RAM, a ROM, a PROM, an EPROM, or a flash memory.

[0022] <Electronic equipment> The electronic device 10 is, for example, a battery-powered electronic device such as a laptop PC. The electronic device 10 includes a battery pack 20, a first processor 11, a switching unit 12, and an antenna 13, and is supplied with power by a battery 21 of the battery pack 20.

[0023] The first processor 11 controls each component of the electronic device 10. The first processor 11 can be realized by a semiconductor element or the like. The first processor 11 can be configured by a microcomputer, a CPU, an MPU, a GPU, a DSP, an FPGA, or an ASIC. The first processor 11 realizes predetermined functions by reading data and programs stored in a storage medium (not shown) and performing various arithmetic processing.

[0024] The first processor 11 controls the switching unit 12 based on the setting of the setting holding unit 23. If the setting of the setting holding unit 23 is changed to "on," the first processor 11 controls the switching unit 12 to connect the battery 21 and the first communication unit 22 when the battery pack 20 is connected to the electronic device 10. If the setting of the setting holding unit 23 is changed to "off," the first processor 11 controls the switching unit 12 to not connect the battery 21 and the first communication unit 22 when the battery pack 20 is connected to the electronic device 10. The first processor 11 can update the setting of the setting holding unit 23 of the battery pack 20 when the battery pack 20 is connected to the electronic device 10. For example, the first processor 11 can update the setting of the setting holding unit 23 by executing a program such as an OS (Operating System) or a BIOS (Basic Input Output System). The first processor 11 corresponds to the "processor" in this disclosure.

[0025] The switching unit 12 is a circuit that switches the electrical connection between the battery 21 and the first communication unit 22 when the battery pack 20 is connected to the electronic device 10. The switching unit 12 switches whether to electrically connect the battery 21 and the first communication unit 22 when the battery pack 20 is connected to the electronic device 10, based on the setting of a setting holding unit 23 included in the battery pack 20. For example, when the setting holding unit 23 is set to "on," the switching unit 12 electrically connects the battery 21 and the first communication unit 22 when the battery pack 20 is connected to the electronic device 10, allowing power to be supplied from the battery 21 to the first communication unit 22. When the setting holding unit 23 is set to "off," the switching unit 12 cuts off the electrical connection between the battery 21 and the first communication unit 22 when the battery pack 20 is connected to the electronic device 10, preventing power from being supplied from the battery 21 to the first communication unit 22.

[0026] 1, the battery 21 and the first communication unit 22 are not electrically connected within the battery pack 20, and are electrically connected via the switching unit 12 when the battery pack 20 is connected to the electronic device 10. The switching unit 12 switches whether or not to connect the battery 21 and the first communication unit 22 based on the setting of the setting holding unit 23.

[0027] The antenna 13 is connected to the first communication unit 22 and transmits and receives radio waves for short-range wireless communication. When the first communication unit 22 uses the antenna 13 disposed in the main body of the electronic device 10, it is not necessary to mount an antenna on the battery pack 20, and therefore the battery pack 20 can be made smaller. Note that the antenna 13 may be disposed in the battery pack 20.

[0028] [Operation] The operations of the electronic device 10 and the battery pack 20 will now be described.

[0029] 1, in the battery pack 20 alone, the battery 21 and the first communication unit 22 are not electrically connected. When the battery pack 20 is connected to the electronic device 10, the battery 21 and the first communication unit 22 are connected via the switching unit 12. In other words, the battery 21 and the first communication unit 22 are electrically connected via the electronic device 10.

[0030] When the battery pack 20 is connected to the electronic device 10, the switching unit 12 switches the connection between the battery 21 and the first communication unit 22 between "on" and "off" based on the setting of the setting holding unit 23 of the battery pack 20. When the setting holding unit 23 is set to "on (connects the battery 21 and the first communication unit 22)", the battery 21 and the first communication unit 22 are electrically connected via the switching unit 12. When the setting holding unit 23 is set to "off (disconnects the battery 21 and the first communication unit 22)", the battery 21 and the first communication unit 22 are not electrically connected.

[0031] In this embodiment, when the power supply of the electronic device 10 is off, power is supplied from the battery 21 to the first communication unit 22. That is, the first communication unit 22 of the battery pack 20 can be used when the power supply of the electronic device 10 is off.

[0032] Furthermore, when the battery 21 and the first communication unit 22 are electrically connected, the first communication unit 22 and the antenna 13 are connected via the switching unit 12. The first communication unit 22 can perform short-range wireless communication with a device external to the electronic device 10 using the antenna 13.

[0033] The external device is, for example, a user-portable information processing terminal such as a smartphone or tablet. When the information processing terminal can perform short-range wireless communication with the first communication unit 22, the information processing terminal can determine that the electronic device 10 is near the information processing terminal. "Near the information processing terminal" means a distance within which close-range wireless communication is possible, for example, within several meters, preferably within 5 meters. Therefore, the information processing terminal can detect the location of the electronic device 10 based on location information from a GPS installed in the information processing terminal. Because the first communication unit 22 of the battery pack 20 and the information processing terminal can perform short-range wireless communication even when the electronic device 10 is powered off, the location of the electronic device 10 can be detected even when the electronic device 10 is powered off.

[0034] [effect] According to the above-described embodiment, it is possible to provide a battery pack and an electronic device that can use a communication function even when the power of the electronic device is turned off.

[0035] By disposing the first communication unit 22 in the battery pack 20, even when the power supply of the electronic device 10 is turned off, power can be supplied from the battery 21 to the first communication unit 22, making it possible to use the short-range wireless communication function. Since the short-range wireless communication function can be used even when the power supply of the electronic device 10 is turned off, it becomes possible to detect the location of the electronic device 10 in a power-off state using an information processing terminal such as a smartphone. Furthermore, because power is supplied from the battery 21 to the first communication unit 22 based on the setting of the setting storage unit 23, power is not supplied when the first communication unit 22 is not being used, thereby enabling power saving.

[0036] Furthermore, for example, when the electronic device 10 is used in a country where the standards or specifications for short-range wireless communication are different, the battery pack 20 can be replaced with one having a corresponding first communication unit 22, thereby making it compatible with various standards or specifications.

[0037] (Embodiment 2) A second embodiment will be described with reference to Fig. 2. In the second embodiment, the same or equivalent configurations as those in the first embodiment will be denoted by the same reference numerals. In the second embodiment, descriptions that overlap with those in the second embodiment will be omitted.

[0038] 2 is a schematic block diagram illustrating an asset management system according to a second embodiment of the present disclosure. In the second embodiment, an asset management system 100 including the electronic device 10 and the battery pack 20 described in the first embodiment will be described.

[0039] The asset management system 100 includes an electronic device 10, a battery pack 20, and an information processing terminal 30. The electronic device 10 and the battery pack 20 are similar to those described in the first embodiment, and therefore a description thereof will be omitted.

[0040] The information processing terminal 30 is a mobile terminal that can be carried by a user and that can perform short-range wireless communication. The information processing terminal 30 has a position information detection unit 31. The information processing terminal 30 also has a second communication unit 32 and a second processor 33.

[0041] The position information detection unit 31 detects position information of the information processing terminal 30. The position information detection unit 31 is, for example, a Global Positioning System (GPS). The position information is, for example, information including latitude and longitude.

[0042] The second communication unit 32 includes a circuit that performs short-range wireless communication in accordance with a predetermined communication standard with the first communication unit 22 of the battery pack 20. The predetermined communication standard includes, for example, Bluetooth (registered trademark).

[0043] The second processor 33 controls each component of the information processing terminal 30. The second processor 33 can be realized by a semiconductor element or the like. The second processor 33 can be configured by a microcomputer, a CPU, an MPU, a GPU, a DSP, an FPGA, an ASIC, or the like.

[0044] When the electronic device 10 and the battery pack 20 are connected, the first communication unit 22 is supplied with power from the battery 21 and is in a state where short-range wireless communication is possible. When the second communication unit 32 performs short-range wireless communication with the first communication unit 22 of the battery pack 20, the information processing terminal 30 acquires position information using the position information detection unit 31. The information processing terminal 30 detects the position of the electronic device 10 based on the acquired position information and the fact that the second communication unit 32 and the first communication unit 22 of the information processing terminal 30 are in short-range communication.

[0045] Fig. 3 is a schematic diagram showing the asset management system of Fig. 2. With reference to Fig. 3, an example in which a plurality of electronic devices 10 are housed in a housing rack 40 and managed will be described.

[0046] For example, if the electronic device 10 is a device such as an inspection laptop PC that an inspector takes out of the storage rack 40, uses, and then returns to the storage rack after use, the asset management system 100 can be used to confirm whether the electronic device 10 has been returned.

[0047] 2, a plurality of electronic devices 10 can be housed in the housing rack 40. An information processing terminal 30 is operated near the housing rack 40 to detect an electronic device 10 that can perform short-range wireless communication with the information processing terminal 30. The information processing terminal 30 can determine that an electronic device 10 that can perform short-range wireless communication with the information processing terminal 30 is located near the information processing terminal 30. In practice, short-range wireless communication is performed between the second communication unit 32 of the information processing terminal 30 and the first communication unit 22 of the battery pack 20.

[0048] At this time, if the location information detected by the location information detection unit 31 indicates the vicinity of the location where the storage rack 40 is installed, the information processing terminal 30 can determine that an electronic device 10 capable of short-range wireless communication is stored in the storage rack 40.

[0049] By providing the first communication unit 22 in the battery pack 20, short-range wireless communication between the electronic device 10 and the information processing terminal 30 is possible even when the power of the electronic device 10 is off. Therefore, it is possible to easily determine whether the electronic device 10 is housed in the housing rack 40, thereby improving the convenience of managing the electronic device 10.

[0050] [Operation] Fig. 4 is a control flowchart of the asset management system of Fig. 2. The operation of the asset management system 100 will be described with reference to Fig. 4.

[0051] 4, in step S1, the battery pack 20 is attached to the electronic device 10. For example, when a user attaches the battery pack to the electronic device 10, the electronic device 10 and the battery pack 20 are connected to each other.

[0052] When the battery pack 20 is connected to the electronic device 10, in step S2, if the power supply of the electronic device 10 is off, power is supplied from the battery 21 of the battery pack 20 to the first communication unit 22. The supply of power from the battery 21 to the first communication unit 22 is performed via the electronic device 10. Specifically, as shown in FIG. 2 , the battery 21 and the first communication unit 22 are electrically connected via the switching unit 12 of the electronic device 10, and power is supplied from the battery 21 to the first communication unit 22. The switching unit 12 connects the battery 21 and the first communication unit 22 based on the setting of the setting holding unit 23 of the battery pack 20.

[0053] When power is supplied from the battery 21 to the first communication unit 22, the battery pack 20 enters a state in which short-range wireless communication is possible. In step S3, the information processing terminal 30 performs short-range wireless communication with the first communication unit 22 of the battery pack 20. In the present embodiment, the second communication unit 32 of the information processing terminal 30 and the first communication unit 22 of the battery pack 20 perform short-range wireless communication. At this time, the information processing terminal 30 can perform short-range wireless communication with the first communication units 22 of the multiple electronic devices 10.

[0054] In step S4, the information processing terminal 30 acquires the position information by the position information detection unit 31.

[0055] In step S5, the information processing terminal 30 detects the position of the electronic device 10 based on the detected position information. The information processing terminal 30 can determine that the electronic device 10 is near the information processing terminal 30 by being able to communicate by short-range wireless communication with the first communication unit 22 of the battery pack 20. Therefore, the position information of the information processing terminal 30 can be used as the position information of the electronic device 10. When the information processing terminal 30 is communicating by short-range wireless communication with multiple electronic devices 10, the information processing terminal 30 can detect the position information of those electronic devices 10 as the position information of the information processing terminal 30.

[0056] [effect] According to the above-described embodiment, it is possible to easily manage a plurality of electronic devices 10. In the asset management system 100 of the second embodiment, even when the power of the electronic device 10 is turned off, short-range wireless communication is possible by the first communication unit 22 of the battery pack 20. Therefore, when the information processing terminal 30 and the electronic device 10 are performing short-range wireless communication, it is possible to know that the electronic device 10 is in a predetermined position by using the location information of the information processing terminal.

[0057] For example, when it is desired to know the number of electronic devices 10 housed in the storage rack 40, all of the electronic devices 10 housed in the storage rack 40 can be known using the information processing terminal 30, thereby saving the user the trouble of counting.

[0058] In the above-described embodiment, the information processing terminal 30 is a smartphone, but the present invention is not limited to this. The information processing terminal 30 may be a mobile terminal having a short-range wireless communication function and a position information detection function. For example, the information processing terminal 30 may be a tablet PC or the like.
