[1. First embodiment]
[1.1 Overall configuration]
First, the entire configuration will be described with reference to FIG. FIG. 1 shows a feed system 1. The terminal device 10, which is a smartphone having the function of a mobile phone, can be connected to a power transmission device (charging device, charger) 20 that can transmit (feed) power. That is, the terminal device 10 can receive power from the power transmission device 20 as an electronic device.

The terminal device 10 can be connected to the network NW via a mobile communication network such as LTE (Long Term Evolution) or 5G (5th Generation), a wireless LAN such as Wi-Fi, a wired LAN, or the like. A server 90 is connected to the network NW. The server 90 is a server that distributes an application that can be executed by the terminal device 10, for example. The terminal device 10 can implement various functions by downloading an application from the server 90 and executing the application.

[1.2 Functional configuration]
Next, the configuration of the power feeding system 1 in the present embodiment will be described with reference to FIG. As illustrated in FIG. 2, the power supply system 1 includes a terminal device 10 (electronic device) and a power transmission device 20.

[1.2.1 Terminal]
The terminal device 10 includes a control unit 100, a storage unit 110, a power reception unit 120, a communication unit 130, a secondary battery 140 as a power supply unit, a display unit 150, an operation unit 155, an audio output unit 160, The camera unit 170 and the wireless communication unit 180 are provided.

  The control unit 100 controls the entire terminal device 10. The control unit 100 implements various functions by reading and executing various programs stored in the storage unit 110, and is configured by, for example, one or more CPUs (Central Processing Units).

  Also, the control unit 100 reads out and executes the program stored in the storage unit 110, whereby the functions of the power reception processing unit 102 and the charge management unit 104 are realized.

  The power reception processing unit 102 realizes a process of supplying power to the secondary battery 140 based on the power received by the power reception unit 120. A method of controlling power supply to a general secondary battery 140, for example, a method in which power is not output to or received from the secondary battery 140 if charging of the secondary battery 140 is completed. For example, high-speed charging / low-speed charging is switched depending on the voltage value.

  The charge management unit 104 is realized by executing the charge management application 112 stored in the storage unit 110. The operation of the charge management unit 104 will be described later with reference to the operation flow.

  The storage unit 110 stores various programs necessary for the operation of the terminal device 10 and various data. The storage unit 110 is configured of, for example, a semiconductor memory (SSD: Solid State Drive), an HDD (Hard Disk Drive) which is a magnetic disk, or the like. The storage unit 110 may include not only an internal storage device but also an external storage device using a semiconductor memory or the like.

  Here, the storage unit 110 stores a charge management application 112. The charge management application may be downloaded and installed via the wireless communication unit 180 or the communication unit 130 described later, or may be stored in the storage unit 110 in advance. Further, it may be installed from an external storage device.

  The power receiving unit 120 receives power from the power transmission device 20. The power receiving unit 120 is configured of, for example, a power receiving coil, and receives power from the power transmission device 20 by an electromagnetic induction method. The method of receiving power may be, for example, a method based on any standard such as Qi, AirFuel Inductive, AirFuel Resonant.

  The communication unit 130 communicates with the power transmission device 20. The communication method may be, for example, short distance wireless communication (Bluetooth (registered trademark), ZigBee (registered trademark), wireless USB, etc.) or wireless communication such as Wi-Fi.

  The secondary battery 140 is a power source for driving the terminal device 10. Charging can be performed by the power received by the power receiving unit 120 being supplied. The secondary battery may be any rechargeable battery, and may be a lithium ion battery, a nickel hydrogen battery, an all solid battery or the like.

  The display unit 150 displays characters, figures, photos, and the like. The control unit 100 can display various information, an operation screen, and the like on the display unit 150. The display unit 150 is configured of, for example, an LCD (Liquid Crystal Display), an organic EL display (Organic LED Display), or the like.

  The operation unit 155 receives an operation input from the user. For example, it is realized by a hardware button or a software button using a touch panel. The present embodiment is realized by a touch panel integrated with the display unit 150.

  The voice output unit 160 can output voice, alarm sound, music, and the like. For example, it is configured by a speaker or an external output terminal to which an external speaker can be connected. Also, the camera unit 170 can capture an image. The captured image is stored in the storage unit 110 as image data.

  The wireless communication unit 180 is a functional unit that is connected to a base station by, for example, LTE communication or the like, and communicates with an external server (for example, an application distribution server that distributes the charge management application 112, the server 90 in FIG. 1). In the present embodiment, the wireless communication unit 180 performs LTE communication, but may perform other communication such as 5G communication, LAA communication, or wireless LAN communication using IEEE802.11a / b / g / n / ac. Good. Also, when the wireless communication unit 180 performs communication other than LTE communication, the wireless communication unit 180 may not perform LTE communication.

[1.2.1 Power Transmission Device]
Subsequently, the functional configuration of the power transmission device will be described. The power transmission device 20 includes a control unit 200, a power transmission unit 210, and a communication unit 220.

  The control unit 200 controls the entire power transmission device 20. The control unit 200 implements various functions by reading and executing various programs stored in the storage unit, and is configured by, for example, one or more CPUs (Central Processing Units).

  The power transmission unit 210 transmits power to the power receiving device. For example, power is wirelessly supplied to the terminal device 10 which is a power receiving device using a power transmission coil. The method of supplying power may be any method as long as the power receiving unit 120 described above can receive power.

  The communication unit 220 communicates with the power receiving device. For example, short-range wireless communication such as Bluetooth is used to communicate with the terminal device 10 which is a power receiving device. Thereby, the power transmission device 20 can acquire the state of the terminal device 10 (for example, the operation mode or the like). The method by which the communication unit 220 communicates may be any method that can communicate with the communication unit 130 described above. For example, the communication unit 220 receives operation mode information indicating an operation mode (a normal operation mode (normal mode), a function restriction mode, or the like) of the terminal device 10. The control unit 200 can obtain the operation mode of the terminal device 10 based on the operation mode information.

[1.3 Flow of processing]
Subsequently, the flow of processing will be described with reference to FIG. This process is a process realized by the control unit 100 executing the charge management application 112 that is downloaded from a server or the like and stored (installed) in the storage unit 110. That is, the control unit 100 functions as the charge management unit 104 by executing the charge management application 112.

  First, when the communication unit 130 receives the identification information transmitted by the power transmission device 20, that is, when the control unit 100 (charge management unit 104) detects the power transmission device 20 with reference to the signal received by the communication unit 130 (step S102; Yes) It is determined whether the operation mode of the terminal device is the function restriction mode (step S104).

  Here, the function restriction mode is an operation mode in which a part of predetermined functions in the terminal device 10 is restricted. In the case of the normal mode, all the predetermined functions in the terminal device 10 can be executed, but in the case of the function restriction mode, for example, the function of the LTE communication is restricted.

  The function restriction mode is specifically described. For example, when the wireless communication unit 180 does not function, the terminal device 10 is restricted in the function of communication (data communication, voice communication, etc.). Furthermore, if the camera unit 170 does not function, shooting can not be performed.

  In addition, that a function is limited includes not only that the function is not available but also that some operations of the function are limited. For example, when the wireless communication unit 180 can also perform communication of a wireless LAN other than LTE communication, the function of the LTE communication may not be available, but the function of the wireless LAN may be limited. In addition, the operation of the display unit 150 (e.g., brightness, reaction rate, etc.) may be limited.

  As described above, in the function restriction mode, the operation of some of the functions of the terminal device 10 or their combination is restricted. The functions to be limited may be limited collectively or the functions set individually may be limited. Further, it may have a plurality of function restriction modes, and these function restriction modes may be set by the user or may be set in advance.

  Then, when the operation mode of the terminal device 10 is not the function restriction mode, the control unit 100 switches the operation mode of the terminal device 10 to the function restriction mode (Step S104; No → Step S106). In the present embodiment, the control unit 100 limits the function of the wireless communication unit 180. Thereby, the communication function of the terminal device 10 is limited.

  Then, the control unit 100 notifies the power transmission device 20 of the function restriction mode from the communication unit 130 (step S108). The power transmission device 20 (the control unit 200) that has received from the communication unit 220 that it is in the function restriction mode starts power transmission from the power transmission unit 210.

  The content notified from the communication unit 130 to the power transmission apparatus 20 is not information indicating whether the terminal device 10 is in the function restriction mode, but information indicating whether the individual functions of the terminal device 10 are restricted. May be. For example, operation mode information is transmitted from the terminal device 10 to the power transmission device 20 as information on the operation mode of the terminal device.

  Accordingly, the terminal device 10 receives power from the power receiving unit 120 and performs power reception processing (charging) (step S110). That is, the power reception processing unit 102 charges the secondary battery 140 based on the received power.

  Here, if the charging is not completed, the process is repeatedly executed from step S104 (step S112; No → step S104). In addition, since what is necessary is just to continue charge, it should just be able to continue and perform at least step S110.

  The end of charging means that the power reception processing unit 102 determines that charging is unnecessary, determines that charging can not be continued, or the user cancels the charging process. In addition, the power reception processing unit 102 determines that charging is unnecessary, for example, when the secondary battery 140 is fully charged or when charging is not required (not charged) when it is in an abnormal state. The power reception processing unit 102 determines that charging can not be continued when the power reception processing unit 102 can not receive power from the power reception unit 120 for a predetermined time.

  Here, when the charging is completed (step S112; Yes), the function restriction mode is released (step S114). That is, all functions in the terminal device 10 can be used.

[1.4 screen example]
An example of the screen of the terminal device 10 will be described with reference to FIG. FIG. 4A is an example of the display screen W100 in the terminal device 10.

  On the display screen W100, an icon M100 indicating a state (remaining battery level) of the secondary battery indicated by an icon or the like and an icon M102 for identifying and displaying a communicable state in the wireless communication unit 180 are displayed. At this time, the operation mode of the terminal device 10 is not the function restriction mode but the normal operation mode.

  Here, when the communication unit 130 receives the identification information transmitted by the power transmission device 20, that is, when the control unit 100 detects the power transmission device 20 with reference to the signal received by the communication unit 130, the function is limited to the display screen W100. A confirmation button R102 for switching to the mode is displayed. Here, a confirmation button R102 is pop-up displayed in the region R100 together with a message indicating that charging is possible.

  Here, when the user selects the confirmation button R102, the operation mode of the terminal device 10 is switched to the function restriction mode, and charging is started. That is, the power transmission device 20 is notified that it is in the function restriction mode, and power transmission from the power transmission device 20 is started.

  FIG. 4B is a diagram showing an example of the display screen W110 being charged. In the icon M100 displayed on the display screen W110, the state of charge is identified and displayed. In addition, the fact that the function restriction mode is currently set is indicated by the icon M104 which is an identification display, and the user can recognize that it is in the restriction mode.

  Further, since the wireless communication unit 180 is limited in function because it is in the function restriction mode, communication can not be performed. An icon M102 indicating the state of the wireless communication unit 180 indicates a state in which communication can not be performed (out-of-service indication).

  In addition, although confirmation button R102 is displayed on area | region R100 in FIG. 4 (a), you may display a cancellation button collectively. Here, when the user selects not the confirmation button R102 but the cancel button, the switching of the operation mode of the terminal device 10 is canceled. That is, the power transmission device 20 is not notified that it is in the function restriction mode, and power transmission from the power transmission device 20 is not started. In this case, even if the power transmission device 20 is nearby, the user can select to continue using the normal mode without performing charging.

  4A, the confirmation button R102 is displayed in the region R100. However, the operation mode of the terminal device 10 may be automatically switched to the function restriction mode without displaying the confirmation button R102. . When the confirmation button R102 is not selected by the user for a predetermined time, the operation mode of the terminal device 10 may be automatically switched to the function restriction mode, or the switching of the operation mode may be canceled. Note that these operations may be set in the initial state of the charge management application 112, or may be set arbitrarily by the user.

  Further, in the present embodiment, it is determined whether or not the terminal device 10 is in the function restriction mode, but the power transmission device 20 may determine whether or not the terminal device 10 is in the function restriction mode. . That is, the terminal device 10 transmits the information related to the restriction of the individual functions of the terminal device 10 to the power transmission device 20, and the power transmission device 20 determines whether to transmit power to the terminal device 10 based on the received information. You may judge.

[1.5 effect]
Thus, according to this embodiment, when charging the terminal device 10 which is an electronic device, the terminal device can be switched to the function restriction mode. Accordingly, for example, in an environment (for example, in an airplane, a movie theater, etc.) in which the user wants to change to the function restriction mode, the user is provided with the direct benefit of supplying power to the user to restrict the function of the terminal device 10. It is possible to ease the sense of burden that the user feels, and to effectively prompt switching to the function restriction mode.

  In particular, for example, in an environment where it is preferable to turn off the communication function, it is possible to give the user a positive motivation to stop using the communication function secretly and switch to the function restriction mode.

  In addition, since the operation mode can be easily switched without performing a complicated operation at the timing of starting or ending charging, it is possible to expect the effect of saving the trouble of switching the operation mode.

  In addition, by limiting a predetermined function during charging, it is also possible to suppress power consumption during charging. As a result, the secondary battery can be charged in a shorter time than usual, or the secondary battery can be charged in an environment with less burden.

[2. Second embodiment]
Subsequently, the second embodiment will be described. The second embodiment is an embodiment in which the termination of the power reception process is determined based on the communication state received by the communication unit 130. Note that the functional configuration is the same as that of the first embodiment, and the description will focus on parts that are different from the first embodiment.

  FIG. 5 is a charge management process according to the second embodiment, which replaces FIG. 3 of the first embodiment. Here, the same reference numerals as in FIG. 3 denote the same parts as in FIG. 3, and a description thereof will be omitted.

  In the present embodiment, when the power reception process is being performed (during charging), it is determined whether or not communication with the power transmission device 20 is possible (step S202). Here, when it is determined that the communication unit 220 of the power transmission device 20 and the communication unit 130 of the terminal device 10 can no longer communicate with each other (step S202; No), the charge management unit 104 stops the power reception process (charges). Discontinue. Then, the function restriction mode is canceled and switched to the normal operation mode (step S114).

  Here, the fact that the communication unit 220 and the communication unit 130 can no longer communicate means, for example, a case where the power transmission device 20 has notified the cancellation of the function restriction or the cancellation of the charging. In addition, when the communication unit 220 and the communication unit 130 can not communicate with each other, the power transmission device 20 may not know whether the terminal device 10 is in the function restriction mode, so power transmission may be stopped.

  As described above, according to the present embodiment, the charging operation of the terminal device 10 can be controlled not only from the terminal device 10 side but also from the power transmission device 20 side.

[3. Third Embodiment]
Subsequently, the third embodiment will be described. In the first embodiment, when receiving power from the power transmission device 20, the process of switching to the function restriction mode is performed. The present embodiment is an embodiment in which switching to the function restriction mode is performed by causing the user side to operate to restrict individual functions. Note that the functional configuration is the same as that of the first embodiment, and the description will focus on parts that are different from the first embodiment.

  FIG. 6 is a charge management process according to the third embodiment, which replaces FIG. 3 of the first embodiment. Here, the same reference numerals as in FIG. 3 denote the same parts as in FIG. 3, and a description thereof will be omitted.

  When the operation mode of the terminal device 10 is not in the function restriction mode, the control unit 100 performs confirmation display to restrict the function (step S302). That is, a confirmation display as to what function is to be restricted is displayed to the user, and the user switches the function restriction mode by restricting the function displayed.

Here, for example, the following method can be considered as the confirmation display for switching the function.
(1) Restrict all functions that can be restricted among the functions of the terminal device 10 (2) Restrict functions necessary for the terminal device 10 to enter the function restriction mode among the functions of the terminal device 10 In the above (2), the display content changes depending on the state of the terminal device 10. For example, it is assumed that the function restriction mode of the terminal device 10 is a mode in which the functions of the camera unit 170 and the wireless communication unit 180 are restricted. At this time, if the function of the wireless communication unit 180 is already restricted by the user (that is, LTE communication cannot be performed), if the function of the camera unit 170 is restricted here, the operation mode of the terminal device 10 is restricted. It will be in mode. Therefore, in this case, the control unit 100 displays a confirmation message for turning off the camera function to the user.

  When it is determined that the function is restricted by the user and the function is switched to the function restriction mode (step S304; Yes), the control unit 100 notifies the power transmission apparatus 20 that the function is in the function restriction mode (step S108).

  A screen example in this case is shown in FIG. FIG. 7A shows an example of a display screen W300 in which a state where power can be received from the power transmission device 20 is detected, but only the camera function is turned on among the functions that must be turned off in the function restriction mode. FIG. That is, in the function restriction mode in the present embodiment, the functions of the camera unit 170 and the wireless communication unit 180 are restricted, and here, the wireless communication unit 180 is already restricted. In the display screen W300, the icon M302 indicates that the function of the wireless communication unit 180 is restricted and that LTE communication can not be performed. Further, the icon M300 indicates that charging has not started.

  Then, on the display screen W300, a message "Please turn off the camera" is displayed in the area R300. Here, the state where the camera is turned off is the display screen W310 shown in FIG. 7 (b).

  In the drawing, since the mode is switched to the function restriction mode, an icon M304 indicating the function restriction mode is displayed. Further, since power reception unit 120 receives power and charges secondary battery 140, icon M300 is switched to the charge display.

[4. Fourth embodiment]
Subsequently, the fourth embodiment will be described. The fourth embodiment is an embodiment in which the installation is performed when the charge management application (program) is not installed. For example, this embodiment is applicable to the case where the provider of the power supply system is executed from another content application. Note that the functional configuration is the same as that of the first embodiment, and the description will focus on parts that are different from the first embodiment.

  FIG. 8 is a charge management process according to the fourth embodiment, which replaces FIG. 3 of the first embodiment. Here, the same reference numerals as in FIG. 3 denote the same parts as in FIG. 3, and a description thereof will be omitted.

  When detecting the power transmission device 20, the control unit 100 determines whether the charge management application 112 is installed (step S402). Here, the detection method of the power transmission device 20 may be based on a request signal from the power transmission device 20 or may be control by another application or the like. For example, the position of the power transmission device 20 is acquired from a server or the like, the current position of the terminal device 10 is acquired from the GPS (not shown) included in the terminal device 10, and the distance between the two is less than a predetermined value. It may be determined that 20 has been detected.

  Then, when the charge management application 112 is not installed, an installation process of the charge application is executed (Step S402; No → Step S404). In the installation process, the home page of the server distributing the charge management application may be automatically displayed to prompt the user for the installation operation, or may be installed automatically. The power transmission device 20 may transmit an application via the communication unit 220, and the terminal device 10 may receive the transmitted application via the communication unit 130 and automatically install the application.

  In step S104 and subsequent steps, the installed charge management application 112 is executed, whereby the control unit 100 functions as the charge management unit 104. That is, when the operation of the predetermined function of the terminal device 10 is restricted, the charge management application 112 realizes a function of transmitting information related to the restriction of the operation to the power transmission device 20 via the communication unit 130. .

  Thus, according to the present embodiment, even when the application is not installed, the charge management application 112 can be installed in the terminal device 10 by the request from the communication unit 220 to the communication unit 130. .

[5. Fifth Embodiment]
Subsequently, the fifth embodiment will be described. In the fifth embodiment, a management server 30 is connected to the power transmission device 20, and the function restriction mode is controlled from the management server 30. Note that the functional configuration is the same as that of the first embodiment, and the description will focus on parts that are different from the first embodiment.

[5.1 Functional configuration]
FIG. 9 is a diagram for explaining a functional configuration in the fifth embodiment. A part of FIG. 2 of the first embodiment is replaced, and the configuration of the terminal device 10 is the same as that of the first embodiment, but the configuration of the wireless communication unit 180 is different.

  The wireless communication unit 180 has functions of the WAN communication unit 182 and the LAN communication unit 184, and can control each communication. The WAN communication unit 182 is a functional unit that performs communication using LTE or the like, and the LAN communication unit 184 is a functional unit that performs communication using a wireless LAN (eg, IEEE802.11a / b / g / n / ac). The LAN communication unit 184 may communicate with an external device existing near the terminal device 10 using a communication method such as Bluetooth.

  The power receiving unit 120, the communication unit 130, and the wireless communication unit 180 in FIG. 9 are connected to the control unit 100 as shown in FIG.

  The management server 30 at least includes a control unit 300, a storage unit 310, and an NW 320 as functions required in the present embodiment. Further, the control unit 300 functions as the terminal function control unit 302 by executing the program stored in the storage unit 310.

  The control unit 300 controls the entire management server 30. The control unit 300 realizes various functions by reading and executing various programs stored in the storage unit 310, and is configured of, for example, one or more CPUs (Central Processing Units).

  The storage unit 310 is a functional unit in which various programs necessary for the operation of the management server 30 and various data are stored. The storage unit 310 is configured of, for example, a semiconductor memory (SSD), an HDD, or the like.

  The storage unit 310 stores a function restriction setting table 312. In the function restriction setting table 312, functions to be restricted in the function restriction mode of the terminal device 10 are stored as function restriction setting information.

  For example, FIG. 10 shows an example of the data configuration of the function restriction setting table 312. The function restriction setting table 312 includes one or more function restriction setting information including a condition (for example, "condition 1"), a function (for example, "LTE communication"), and a restriction (for example, "OFF") It is remembered. Here, the conditions are conditions under which the function restriction setting information is used, and include, for example, date and time, time, place, terminal model name, performance, and the like.

  Here, with regard to the restriction, when "OFF" is stored, the execution of the function is restricted. That is, the function cannot be executed. In the case of “ON”, it can be executed without any particular limitation.

  The NW (network) unit 320 communicates with the power transmission device 20. The NW unit 320 is configured by, for example, a LAN interface, a USB interface, or the like. The power transmission device 20 also includes an NW unit 230 that communicates with the management server 30. The NW unit 320 and the NW unit 230 may be connected so as to be communicable. For example, the NW unit 320 and the NW unit 230 may be indirectly connected via a LAN or the Internet, or may be directly connected via a USB cable or the like. Moreover, although the power transmission apparatus 20 has the communication part 220 and the NW part 230 for convenience of explanation, it may be implement | achieved by one function part by wireless LAN etc., for example.

[5.2 Flow of processing]
FIG. 11 shows a charge management process according to the fifth embodiment, which replaces FIG. 3 of the first embodiment. Here, the same reference numerals as in FIG. 3 denote the same parts as in FIG.

  If the power transmission device 20 is detected (step S102; Yes), the control unit 100 receives the function restriction setting information from the power transmission device 20 via the communication unit 130 (step S502). The control unit 100 stores the received function restriction setting information in the storage unit 110.

  Here, the function restriction setting information transmitted from the power transmission device 20 is transmitted from the management server 30 to the power transmission device 20 according to the installation environment of the power transmission device 20. Since the terminal device 10 receives the function restriction setting information from the power transmission device 20 and sets the function restriction mode according to the function restriction setting information, the function restriction of the terminal device 10 corresponds to the installation environment of the power transmission device 20. It will be a thing.

  In step S104, the control unit 100 determines that the terminal device 10 is in the function restriction mode when the execution of each functional unit is restricted to the function restriction mode in accordance with the function restriction setting information.

  In addition, when there is a change in the function restriction setting information during power reception processing (during charging) (step S504; Yes), the function restriction setting information is received again (step S502), and the terminal device 10 is in the function restriction mode. It is determined whether or not.

  Here, the determination as to whether the function restriction setting information has been changed may be performed periodically by the terminal device 10 or may be performed at the timing when the notification signal is received from the power transmission device 20. When the condition is transmitted to the terminal device 10, it may be determined that the function restriction setting information has changed when the condition is not met.

[5.3 Application example]
Subsequently, an application example in the present embodiment will be described with reference to FIG. 12A shows function restriction setting information in the power supply system provided in the airplane, and FIG. 12B shows function restriction setting information in the power supply system provided in the movie theater.

  For example, in the case of the plane of FIG. 12A, time t10 to time t12 indicates takeoff, time t12 to time t14 indicates flight, and time t14 to time t16 indicate time of landing. These times are stored as conditions, and operation restrictions of each function are determined according to the conditions.

  At the time of takeoff and landing, execution of the WAN communication unit 182 (for example, LTE communication) of the wireless communication unit 180 and the LAN communication unit 184 (for example, wireless LAN) is restricted as the function restriction mode. On the other hand, at the time of flight, the functions of the WAN communication unit 182 are restricted, but the other functions are not restricted. Therefore, the user can use functions other than the function (LTE) of the WAN communication unit 182.

  In the case of the movie theater of FIG. 12 (b), the screening time is set as the condition. Here, the time from t22 to t26 is the movie showing time. Therefore, no functional restriction is performed before (t20 to t22) and after (t26 to t28) the screening time.

  Here, at the screening time, the camera and the recording function are limited and can not be performed (time t22 to time t26) for the purpose of preventing recording and recording. In addition, the function (LTE) of the WAN communication unit 182 is also restricted, and the call is prohibited.

  In addition, the function (wireless LAN) of the LAN communication unit 184 is limited when the screening of the main feature starts (time t24 to time t26). As described above, the function restriction of the terminal device 10 can be performed according to the schedule intended by the administrator (the host, the operator of the power supply system).

[6. Sixth embodiment]
Subsequently, a sixth embodiment will be described. The sixth embodiment is an embodiment in which the function restriction mode is set on the side of the terminal device 10 according to the environment and the power transmission device to be connected. Note that the functional configuration is the same as that of the first embodiment, and the description will focus on parts that are different from the first embodiment.

  FIG. 13 is a table showing the function restriction mode in this embodiment. For this table, the operation in the function restriction mode is set for each function according to the environment. This table is stored in the storage unit 110.

  For example, as shown in FIG. 13A, this table stores the correspondence between functions, environments, and ON / OFF (whether or not to limit functions). For example, when using the power transmission device 20 in an airplane, LTE communication is “OFF”. That is, the function is limited. The wireless LAN is “ON” (available), and NFC is “ON” (available).

  This setting is set as necessary. For example, the reason why LTE communication is turned off is to avoid affecting the control device in the plane. The camera is turned off in order to prevent illegal shooting in a movie theater or the like. The recording is turned off in order to prevent illegal recording at a concert hall or the like. The wireless LAN is turned on in order to provide a wireless LAN environment as an alternative means in an environment in which the LTE communication is turned off. The NFC is turned on so that it can be searched whether the NFC card is in the vicinity at the time of charging.

  Thus, in the present embodiment, the function restriction mode is set so that the necessary functions are controlled according to the environment. Further, whether or not to restrict a plurality of functions may be collectively set according to these environments.

  For example, FIG. 13B is a table for collectively setting whether or not to restrict a plurality of functions for each environment. For example, when receiving power from a power transmission device installed in an airplane, LTE communication "OFF", wireless LAN "ON", camera "ON", recording "ON", music reproduction "ANY", NFC "ON" as function restriction mode Is set.

  Here, "ANY" indicates that either "ON / OFF" is acceptable. That is, functions that are not controlled in the function restriction mode are shown.

  In the present embodiment, the charge management process of FIG. 3 is executed. At this time, when the power transmission device 20 is detected in step S102, the control unit 100 determines the setting of the function restriction mode according to the environment of the power transmission device 20.

  For example, if the installation place of the power transmission device 20 is a movie theater, it is determined that the function restriction mode suitable for the movie theater is set. Thus, the terminal device is automatically set to a state according to the environment of the power transmission device 20.

  The environment (place) of the power transmission device 20 may be notified from the power transmission device 20, or the terminal device 10 may acquire information on the installation place of the power transmission device 20. Also, for example, position information of the terminal device 10 may be acquired from a GPS or an LTE base station, and the environment (the installation place of the power transmission device 20) may be determined according to the position information.
