  When the supply of power from the cell 1 is started, the power supply control unit 31 determines whether or not the voltage generated by the cell 1 is equal to or higher than the first voltage value.

  The first voltage value is the lowest voltage value at which it can be determined whether or not the battery pack 10 is a regular battery pack.

  When the voltage generated by the cell 1 is equal to or higher than the first voltage value, the power supply control unit 31 detects that the battery pack 10 is connected to the electronic device 50 and transmits the connection detection information to the main body side authentication unit 33 (specifically, Is output to the authentication information processing unit 34).

  On the other hand, when the voltage generated by the cell 1 is not equal to or higher than the first voltage value, the power supply control unit 31 waits until the cell 1 is charged and the voltage generated from the cell 1 becomes equal to or higher than the first voltage value. Specifically, when the battery pack 10 is connected to a charger, the battery pack 10 is charged until the voltage generated in the cell 1 becomes equal to or higher than the first voltage value. Thereafter, when the voltage supplied from the cell 1 becomes equal to or higher than the first voltage value, it is detected that the battery pack 10 is connected to the electronic device 50, and the connection detection information is sent to the main body side authentication unit 33 (specifically, authentication).

  The main body side signal switching unit 36 is controlled by the authentication information processing unit 34 and connects the main body side information terminal 22B to either the temperature information processing unit 35 or the authentication information processing unit 34.

  When the authentication information processing unit 34 receives the connection detection information from the power supply control unit 31, the authentication information processing unit 34 controls the main body side signal switching unit 36 to connect the main body side information terminal to itself (the authentication information processing unit 34). An identifier acquisition request for acquiring the identifier is output to the battery pack 10 via the main body side signal switching unit 36 and the main body side information terminal 22B.

  At this time, since the pack-side signal switching unit 6 connects the pack-side information terminal 22A and the authentication control unit 7, the authentication control unit 7 accepts an identifier acquisition request.

  When the authentication information processing unit 34 receives the identifier of the battery pack 10 from the authentication control unit 7, the authentication information processing unit 34 determines whether or not the battery pack 10 is a regular battery pack based on the received identifier.

  Specifically, the authentication information processing unit 34 holds an identifier indicating a regular battery pack, and determines whether or not the identifier received from the authentication control unit 7 matches the held identifier. . If these identifiers match, the authentication information processing unit 34 determines that the battery pack 10 is a regular battery pack. On the other hand, if these identifiers do not match, the authentication information processing unit 34 determines that the battery pack 10 is not a regular battery pack.

  Hereinafter, a case where the battery pack 10 is determined to be a regular battery pack will be described first, and then a case where it is determined that the battery pack 10 is not a regular battery pack will be described.

  When it is determined that the battery pack 10 is a regular battery pack, the authentication information processing unit 34 outputs authentication completion information indicating that the authentication is completed to the authentication control unit 7.

  Further, the authentication information processing unit 34 outputs charging permission information indicating charging permission of the power pack 10 (specifically, the cell 1) to the power control unit 31.

  When the authentication information processing unit 34 outputs the charging permission information, the authentication information processing unit 34 connects the main body side signal switching unit 36 to the temperature information processing unit 35.

  When the power supply control unit 31 receives the charging permission information from the authentication information processing unit 34, the power supply control unit 31 determines whether or not the battery pack 10 is connected to the charger.

  When the battery pack 10 is connected to the charger, the temperature information processing unit 35 receives temperature information from the temperature sensor unit 4 and outputs the received temperature information to the power supply control unit 31.

  When the temperature information received from the temperature sensor unit 4 is analog information, the temperature information processing unit 35 may convert the analog information into digital information and output the temperature information to the power supply control unit 31 as digital information.

  The power supply control unit 31 receives temperature information from the temperature information processing unit 35 and determines whether or not the temperature indicated by the received temperature information is included in a predetermined range.

  When it is determined that the temperature is included in the predetermined range, the power supply control unit 31 starts charging from the charger to the cell 1 and charges while the temperature is determined to be included in the predetermined range. Continue.

  On the other hand, when it is determined that the temperature is not included in the predetermined range, the power supply control unit 31 stops charging the battery 1 from the charger and charges until it is determined that the temperature is included in the predetermined range. Continue to stop.

  On the other hand, when the battery pack 10 is not connected to the charger, the power supply control unit 31 determines whether or not the voltage generated in the cell 1 is equal to or higher than the second voltage value.

  The second voltage value is the lowest voltage value at which the electronic device 50 can perform a normal operation.

  The second voltage value is approximately the same as the first voltage value.

  The display unit 44 is, for example, a liquid crystal display and displays various types of information.

  When the function control unit 32 receives normal voltage information from the power supply control unit 31, the function control unit 32 outputs a normal display request for displaying the standby screen set by the user on the display unit 44 to the drive control unit 37.

  When receiving a normal display request from the function control unit 32, the drive control unit 37 causes the display unit 44 to display a standby screen set by the user.

  On the other hand, when it is determined that the voltage generated in the cell 1 is not equal to or higher than the second voltage value, voltage drop information indicating that the voltage generated in the cell 1 is not equal to or higher than the second voltage value is output to the function control unit 32.

  Upon receiving the voltage drop information from the function control unit 32, the drive control unit 37 operates the notification unit 60, for example, generates a warning sound in the speaker 43, and notifies the user of the lack of power in the battery pack 10.

  Next, a case where it is determined that the battery pack 10 is not a regular battery pack will be described.

  When it is determined that the battery pack 10 is not a regular battery pack, the authentication information processing unit 34 indicates to the power supply control unit 31 and the function control unit 32 that charging of the power supply pack 10 (specifically, cell 1) is not permitted. Outputs charging disapproval information.

  The function control unit 32 receives the charging non-permission information from the authentication information processing unit 34 and outputs the received charging non-permission information to the drive control unit 37.

  When the drive control unit 37 receives the charge non-permission information from the function control unit 32, the drive control unit 37 operates the notification unit 60 to notify the user that the battery pack 10 connected to the electronic device 50 is not a regular battery pack.

  For example, the drive control unit 37 causes the light emitting unit 41 to emit light, operates the vibrator motor 42 to vibrate the electronic device 50, operates the speaker 43 to generate a warning sound, or causes the battery pack 10 to be properly displayed on the display unit 44. A character or an image for notifying that the battery pack is not displayed.

  A plurality of these operations may be used. For example, the drive control unit 37 may cause the light emitting unit 41 to emit light and display a character or an image for notifying that the battery pack 10 is not a regular battery pack on the display unit 44.

  When the power supply control unit 31 receives the charging non-permission information from the authentication information processing unit 34, the power supply control unit 31 determines whether a battery charger is connected to the battery pack 10.

  When the charger is connected to the battery pack 10, the power supply control unit 31 stops charging the cell 1 from the charger.

  On the other hand, when the charger is not connected to the battery pack 10, the power supply control unit 31 determines whether or not the voltage generated in the cell 1 is equal to or higher than the second voltage value.

  When the voltage generated in the cell 1 is equal to or higher than the second voltage value, the power supply control unit 31 outputs voltage normality information to the function control unit 32.

  When function control unit 32 receives normal voltage information from power supply control unit 31, function control unit 32 outputs normal display information to drive control unit 37.

  Upon receiving the normal display information from the function control unit 32, the drive control unit 37 causes the display unit 44 to display a normal standby screen set by the user.

  After that, even if the charger is connected to the battery pack, the power supply control unit 31 does not charge the cell 1 from the charger.

  Next, the operation will be described.

  FIG. 4 is a flowchart for explaining the operation of the electronic device system.

  The pack side positive terminal 21A and the main body side positive terminal 21B, the pack side negative terminal 23A and the main body side negative terminal 23B, and the pack side information terminal 22A and the main body side information terminal 22B are connected. Further, the authentication control unit 7 controls the pack side signal switching unit 6 to connect the pack side information terminal to itself (the authentication control unit 7).

  Thereafter, in step 401, the power supply control unit 31 determines whether or not the voltage generated in the cell 1 is equal to or higher than the first voltage value. If the voltage is not greater than or equal to the first voltage value, power supply control unit 31 executes step 402, while if the voltage is greater than or equal to the first voltage value, step 404 is performed.

  In step 402, the power supply control unit 31 stands by until the voltage generated in the cell 1 becomes equal to or higher than the first voltage value. Specifically, when the battery pack 10 is connected to a charger, the battery pack 10 is charged until the voltage generated in the cell 1 becomes equal to or higher than the first voltage value. The power supply control unit 31 executes Step 403 after completing Step 402.

  In step 403, the power supply control unit 31 detects that the voltage generated in the cell 1 is equal to or higher than the first voltage value. When the power supply control unit 31 detects that the voltage has become equal to or higher than the first voltage value, the power supply control unit 31 executes Step 404.

  In step 404, the power supply control unit 31 detects that the battery pack 10 is connected to the electronic device 50, and outputs connection detection information to the authentication information processing unit 34.

  Upon receipt of connection detection information from the power supply control unit 31, the authentication information processing unit 34 connects the main body side signal switching unit 36 to the authentication information processing unit 34. Upon completion of step 404, the authentication information processing unit 34 executes step 405.

  In step 405, the authentication information processing unit 34 outputs an identifier acquisition request to the authentication control unit 7. When the authentication information processing unit 34 outputs an identifier acquisition request, the authentication control unit 7 executes Step 406.

  In step 406, upon receiving the identifier acquisition request from the authentication information processing unit 34, the authentication control unit 7 outputs the retained identifier to the authentication information processing unit 34. When the authentication information processing unit 34 receives the identifier from the authentication control unit 7, the authentication information processing unit 34 executes Step 407.

  In step 407, the authentication information processing unit 34 determines whether or not the battery pack 10 is a regular battery pack based on the received identifier.

  Specifically, the authentication information processing unit 34 holds an identifier indicating a regular battery pack, and determines whether or not the identifier received from the authentication control unit 7 matches the held identifier. . If these identifiers match, the authentication information processing unit 34 determines that the battery pack 10 is a regular battery pack. On the other hand, if these identifiers do not match, the authentication information processing unit 34 determines that the battery pack 10 is not a regular battery pack.

  The authentication information processing unit 34 executes Step 408 if the battery pack 10 is a regular battery pack, and executes Step 421 if the battery pack 10 is not a regular battery pack.

  In step 408, the authentication information processing unit 34 outputs authentication completion information indicating that the authentication has been completed to the authentication control unit 7. When the authentication information processing unit 34 outputs the authentication completion information, the authentication information processing unit 34 executes Step 409.

  In step 409, the authentication information processing unit 34 outputs charging permission information indicating charging permission of the cell 1 to the power supply control unit 31. When the authentication information processing unit 34 outputs the charging permission information, the authentication control unit 7 executes Step 410.

  In step 410, upon receiving the authentication completion information from the authentication information processing unit 34, the authentication control unit 7 connects the pack side signal switching unit 6 to the temperature sensor unit 4. When the authentication control unit 7 finishes step 410, the authentication information processing unit 34 executes step 411.

  In step 411, the authentication information processing unit 34 connects the main body side signal switching unit 36 to the temperature information processing unit 35. When the authentication information processing unit 34 finishes step 411, the power supply control unit 31 executes step 412.

  In step 412, the power supply control unit 31 determines whether or not the battery pack 10 is connected to the charger. If the battery pack 10 is connected to the charger, the temperature sensor unit 4 executes step 413. On the other hand, if the battery pack 10 is not connected to the charger, the power supply control unit 31 executes step 418.

  In step 413, the temperature sensor unit 4 detects the temperature of the battery pack 10 and outputs temperature information indicating the detected temperature to the temperature information processing unit 35. When the temperature information processing unit 35 receives temperature information from the temperature sensor unit 4, the temperature information processing unit 35 executes Step 414.

  In step 414, the temperature information processing unit 35 outputs temperature information to the power supply control unit 31.

  The power supply control unit 31 receives temperature information from the temperature information processing unit 35. When the power supply control unit 31 receives the temperature information, the power supply control unit 31 executes Step 415.

  In step 415, the power supply control unit 31 determines whether or not the temperature indicated by the temperature information received from the temperature information processing unit 35 is included in a predetermined range. The cell 1 executes Step 416 when the temperature is included in the predetermined range, and executes Step 417 when the temperature is not included in the predetermined range.

  In step 416, cell 1 starts charging.

  In step 417, cell 1 stops charging.

  In step 418, the power supply control unit 31 determines whether or not the voltage generated in the cell 1 is equal to or higher than the second voltage value. The power supply control unit 31 executes step 419 if the voltage is equal to or higher than the second voltage value, and executes step 420 if the voltage is not equal to or higher than the second voltage value.

  In step 419, the power supply control unit 31 outputs voltage normal information indicating that the voltage generated in the cell 1 is equal to or higher than the second voltage value to the function control unit 32.

  The function control unit 32 receives normal voltage information from the power supply control unit 31, and outputs a normal display request for displaying the standby screen set by the user on the display unit 44 to the drive control unit 37.

  When receiving a normal display request from the function control unit 32, the drive control unit 37 causes the display unit 44 to display a standby screen set by the user. When the drive control unit 37 displays a standby screen, the power supply control unit 31 executes Step 418.

  On the other hand, in step 420, the power supply control unit 31 outputs voltage drop information indicating that the voltage generated in the cell 1 is not equal to or higher than the second voltage value to the function control unit 32.

  The function control unit 32 receives voltage drop information from the power supply control unit 31 and outputs the received voltage drop information to the drive control unit 37.

  Upon receiving the voltage drop information from the function control unit 32, the drive control unit 37 operates the notification unit 60, for example, generates a warning sound in the speaker 43, and notifies the user of the lack of power in the battery pack 10. When the drive control unit 37 ends step 420, the power supply control unit 31 executes step 412.

  In step 421, the authentication information processing unit 34 outputs charging non-permission information indicating charging non-permission of the cell 1 to the power supply control unit 31 and the function control unit 32. When the authentication information processing unit 34 outputs the charging non-permission information, the function control unit 32 executes Step 422.

  In step 422, the function control unit 32 receives the charging non-permission information from the authentication information processing unit 34 and outputs the received charging non-permission information to the drive control unit 37.

  When the drive control unit 37 accepts the charging non-permission information from the function control unit 32, the drive control unit 37 operates the notification unit 60, for example, causes the light emitting unit 41 to emit light, and the battery pack 10 connected to the electronic device 50 is authorized by the user. Notify that the battery pack is not. When the drive control unit 37 finishes step 422, the power supply control unit 31 executes step 423.

  In step 423, the power supply control unit 31 determines whether or not a charger is connected to the battery pack 10. The power supply control unit 31 executes Step 424 when the charger is connected, and executes Step 425 when the charger is not connected.

  In step 424, the power supply control unit 31 stops charging the cell 1.

  In step 425, the power supply control unit 31 determines whether or not the voltage generated in the cell 1 is equal to or higher than the second voltage value. The power supply control unit 31 executes step 426 if the voltage is equal to or higher than the second voltage value, and executes step 423 if the voltage is not equal to or higher than the second voltage value.

  In step 426, the power supply control unit 31 outputs voltage normal information indicating that the voltage generated in the cell 1 is equal to or higher than the second voltage value to the function control unit 32.

  When function control unit 32 receives normal voltage information from power supply control unit 31, function control unit 32 outputs normal display information to drive control unit 37.

  When the drive control unit 37 receives normal voltage information from the function control unit 32, the drive control unit 37 causes the display unit 44 to display a normal standby screen set by the user.

  According to the present embodiment, if the voltage generated in the battery pack 10 is not equal to or higher than the first voltage value, the power supply control unit 31 charges until the voltage of the cell 1 reaches the first voltage value. To do.

  When the voltage of the cell 1 becomes equal to or higher than the first voltage value, the authentication information processing unit 34 determines whether or not the battery pack 10 is a regular battery pack based on the identifier output from the authentication control unit 7.

  When it is determined that the battery pack 10 is a regular battery pack, the main body side signal switching unit 36 connects the main body side information terminal 22 </ b> B to the temperature information processing unit 35.

  The temperature information processing unit 35 receives temperature information from the temperature sensor unit 4 and outputs the received temperature information to the power supply control unit 31.

  The power supply control unit 31 receives temperature information from the temperature information processing unit 35 and controls charging of the battery pack 10 based on the received temperature information.

  Thereby, when the voltage generated in the battery pack 10 is less than the first voltage value, the battery pack 10 is charged until the voltage reaches the first voltage value, and then the battery pack 10 is a regular battery pack. It is determined whether or not. When it is determined that the battery pack 10 is a regular battery pack, charging is controlled. Therefore, authentication as to whether or not the battery pack 10 is a regular battery pack can be performed after sufficient power is supplied to perform authentication. Therefore, even after the battery pack 10 has insufficient power, it can be operated thereafter.

  In this embodiment, when it is determined that the battery pack 10 is not a regular battery pack, the notification unit 60 notifies the user that the battery pack 10 is not a regular battery pack.

  Thereby, the user can know that the battery pack 10 is not a regular battery pack.

  In the present embodiment, when the battery pack 10 is connected to the electronic device 50, the pack-side signal switching unit 6 connects the pack-side information terminal 22 </ b> A to the authentication control unit 7.

  The authentication control unit 7 outputs the identifier to the electronic device 50.

  When the authentication control unit 7 determines that the battery pack 10 is a regular battery pack, the pack-side signal switching unit 6 connects the pack-side information terminal 22 </ b> A to the temperature sensor unit 4.

  The temperature sensor unit 4 outputs temperature information to the electronic device 50.

  Thereby, when the battery pack 10 and the electronic device 50 are connected, an identifier is output. After that, when it is determined that the battery pack 10 is a regular battery pack, temperature information is output. Therefore, when the electronic device 50 receives the temperature information, the electronic device 50 controls the charging of the battery pack based on the received temperature information. Therefore, if the battery pack 10 is a regular battery pack, the electronic device 50 can charge the battery pack 10. It becomes possible.

  FIG. 2 is a block diagram showing an embodiment of the electronic device system of the present invention. Further, FIG. 2 shows that if the battery pack 10 is not a regular battery pack, the power supplied to the electronic device 50 can be stopped regardless of whether the battery pack 10 is connected to the charger. It is the block diagram which showed an example of the possible electronic device system. In the following, a configuration different from FIG. 1 will be mainly described.

  In FIG. 2, the electronic device system includes a battery pack 10 and an electronic device 50.

  The battery pack 10 has the same configuration as that shown in FIG.

  Electronic device 50 further includes a power supply switching unit 38 in addition to the configuration shown in FIG. In addition to the configuration shown in FIG. 1, the main body side authentication unit 33 further includes a main body side timer unit 39.

  The power supply control unit 31 supplies the power from the cell 1 to the devices in the electronic device 50, but the main body timer unit 39 uniquely receives the power from the cell 1.

  The power supply switching unit 38 is controlled by the authentication information processing unit 34 and the main body side timer unit 39, and switches the power supply control unit 31 between power supply and disconnection from the cell 1.

  The power supply switching unit 38 is connected to a side that supplies power from the cell 1 to the power supply control unit 31 as an initial state.

  When the authentication information processing unit 34 determines that the battery pack 10 is a regular battery pack, the electronic device system performs the operation described with reference to FIGS. 1 and 2.

  On the other hand, when it is determined that the battery pack 10 is not a regular battery pack, the authentication information processing unit 34 does not permit the power supply control unit 31 and the function control unit 32 to charge the power supply pack 10 (specifically, the cell 1). Is output, and the power source switching unit 38 is switched to the power source control unit 31 so that the power from the cell 1 is cut off.

  Thereby, the supply of power from the cell 1 to the electronic device 50 is stopped.

  When the authentication information processing unit 34 switches the power source switching unit 38 to the power source control unit 31 so that the power from the cell 1 is cut off, the main body side timer unit 39 controls the power source switching unit 38 when the predetermined time elapses. Setting is made to switch the unit 31 to the power supply side.

  When the predetermined time set by the authentication information processing unit 34 has elapsed, the main body side timer unit 39 switches the power supply switching unit 38 to the side supplying power to the power supply control unit 31, and switches the power supply control unit 31 from the cell 1.

  When the authentication information processing unit 34 switches the power source switching unit 38 to the power source control unit 31 so as to cut the power from the cell 1, the main body side timer unit 39 controls the power source switching unit 38 when the predetermined time elapses. Setting to switch to the side for supplying power to the unit 31 is performed. When the authentication information processing unit 34 ends Step 502, the main body side timer unit 39 executes Step 503.

  In step 503, the main body timer unit 39 detects that a predetermined time set by the authentication information processing unit 34 has elapsed. When the main body side timer unit 39 finishes step 503, it executes step 504.

  The main body timer unit 39 switches the connection of the power supply switching unit 38 to the power supply unit 31 that supplies power from the cell 1. When the main body side timer unit 39 finishes step 503, the power supply control unit 31 executes step 401.

  According to the present embodiment, if the battery pack 10 is not a regular battery pack, the power supply switching unit 38 cuts power to the power supply control unit 31. Thereafter, when a predetermined time elapses, the power supply switching unit 38 supplies power to the power supply control unit 31.

  Thereby, if the battery pack 10 is not a regular battery pack, the electronic device 50 cannot be used. Since electric power is supplied after a predetermined time has elapsed, the electronic device 50 can be used if the battery pack 10 is replaced with a regular battery pack while the electronic device 50 cannot be used.

  When the retry control unit 40 receives the authentication nonconformity information from the authentication information processing unit 34, the retry control unit 40 adds 1 to the number of authentication nonconformances held and updates the number of authentication nonconformances. When the retry control unit 40 updates the number of authentication nonconformances, the retry control unit 40 executes Step 802.

  In step 802, the retry control unit 40 determines whether or not the updated number of times of authentication nonconformity is a predetermined number or more. The retry control unit 40 executes step 803 if the number of authentication nonconformities is equal to or greater than a predetermined number, and executes step 804 if the number of authentication nonconformities is not equal to or greater than the predetermined number.

  In step 803, the retry control unit 40 outputs a determination end request to the authentication information processing unit 34 to end the determination of whether or not the battery pack 10 is a regular battery pack. When the authentication information processing unit 34 receives a determination end request from the retry control unit 40, the authentication information processing unit 34 executes Step 421.

  On the other hand, in step 804, the retry control unit 40 outputs a re-determination request to the authentication information processing unit 34 to determine whether or not the battery pack 10 is a regular battery pack. When the authentication information processing unit 34 receives a re-determination request from the retry control unit 40, the authentication information processing unit 34 executes Step 404.

  According to the present embodiment, the retry control unit 40 determines whether or not the updated number of times of authentication nonconformity is a predetermined number or more.

  If it is determined that the number of authentication nonconformities is not equal to or greater than the predetermined number, the authentication information processing unit 34 outputs an identifier acquisition request to the authentication control unit 7. When the authentication information processing unit 34 receives the identifier output from the authentication control unit 7, the authentication information processing unit 34 again determines whether or not the battery pack 10 is a regular battery pack based on the received identifier. In other words, when it is determined that the number of times of authentication nonconformity updated by the retry control unit 40 is not equal to or greater than a predetermined number, the authentication control unit 7 determines again whether or not the battery pack 10 is a regular battery pack.
