Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a block diagram showing a configuration of a mobile phone 10 according to an embodiment of the present invention. Note that the configuration shown in FIG. 1 is simplified for the purpose of explaining the present invention, and is assumed to include components mounted on a normal mobile terminal.

  The cellular phone 10 includes a main control unit 11 that controls the entire apparatus, a transmission / reception unit 12 that performs communication by mobile communication with a mobile communication center (not shown) via a mobile communication network (not shown), A display unit 13 having an LCD (Liquid Crystal Display) configuration for displaying various data such as the operating state of the system, an input unit 14 for performing an input operation, and an instruction input via the input unit 14 as a main control unit 11, an input control unit 15 to be supplied to the application 11, an application control unit 19 that activates various applications installed or downloaded in the apparatus, a microphone 16 for inputting voice, and a function for outputting received voice data A speaker 17, a device connection unit 21 for connecting various devices, a boot control unit 22 for starting the system, and a standard for storing a standard operating system The quasi-OS storage unit 23, the emergency operation mode OS storage unit 24 that stores the operating system for the emergency operation mode, the emergency operation various information storage unit 25 that stores various types of emergency operation information, and the emergency operation An emergency operation mode control unit 26 that executes processing according to an emergency operation using various information, a connector C11 for connecting the battery pack 30, a connector C12 for connecting the external power source 29, the battery 30 or the external It is mainly composed of a power supply control unit 40 that supplies power to each unit using the power supplied from the power supply 29. In addition to controlling the power supply control unit 40, the main control unit 11 performs various controls such as storage and reading of information in the various emergency operation information storage unit 25.

  Here, in the present embodiment, for example, a lithium ion battery is used as the battery 31. In a battery such as a lithium ion battery, when the voltage drop progresses and reaches a battery overdischarge limit voltage (hereinafter referred to as a battery protection voltage), it becomes difficult to exhibit its original performance even if charging is performed. For this reason, in the mobile phone 10, the power supply control unit 40 includes a battery voltage detection unit 40b included in the power supply control unit 40 as a basic normal operation from the viewpoint of preventing abnormal operation of the mobile device and from the viewpoint of battery protection. Thus, while the battery voltage of the battery 31 is monitored, when the battery voltage falls below a predetermined voltage, control is performed to stop the system operation and stop the battery consumption. That is, in the power supply control unit 40, the operation limit voltage of the circuit existing inside the mobile device (mobile phone 10) (hereinafter referred to as the mobile device internal circuit operation limit voltage) and the overdischarge limit voltage of the battery 31 are set. In addition, a system operation limit voltage (hereinafter referred to as a mobile device operation limit voltage) is set, and a voltage region in which the voltage of the battery 31 is higher than the mobile device operation limit voltage is set in the mobile device (mobile phone 10). In this area, power is supplied to the system. When the voltage of the battery 31 falls below the mobile device operating limit voltage, the system is stopped and the battery 31 is consumed. Control not to do.

  In the case of the present embodiment, as shown in FIG. 2, in the battery 31 of the lithium ion battery configuration, the voltage in the fully charged state is 4.251 [V], and the battery protection voltage is 2.294 [V]. . In the voltage control unit 40, the mobile device operation limit voltage is set as 3.4 [V], and the mobile device internal circuit operation limit voltage of the mobile phone 10 is set as 2.9 [V] in advance. In the verification experiment, when the voltage of the battery 31 is the mobile device operation limit voltage, there is a remaining capacity of 37.15 [mAh], and when the mobile device internal circuit operation limit voltage is reached, It was found that there was a remaining capacity of 6.76 [mAh].

  FIG. 3 is a graph showing the battery voltage of the battery 31 and the remaining battery capacity (remaining battery capacity). As shown in FIG. 3, it is assumed that the remaining battery level changes as indicated by, for example, the characteristic curve C <b> 1 by using the mobile phone 10 from a fully charged battery 31. In this case, the mobile device operation limit voltage is Vl [V], the mobile device internal circuit operation limit voltage is Vc [V], and the battery protection voltage is Vp [V].

  When the battery voltage changes as described above, assuming that the power consumption required for the emergency operation is a known value Am [mAh], the relationship between the assumed threshold values, the battery voltage, and the remaining battery level is shown in FIG. There are 10 patterns (status (1) to status (10)).

  The status (1) shown in FIG. 3 indicates that the mobile phone 10 starts emergency operation when the power is on (battery voltage is greater than the mobile device operation limit voltage Vl), and the battery voltage remains at the mobile device operation limit even after the operation ends. The pattern is a voltage Vl or higher. Status (2) is a pattern in which an emergency operation is started when the mobile phone 10 is powered on (battery voltage is greater than the mobile device operation limit voltage Vl), and the battery voltage falls below the mobile device operation limit voltage Vl during operation. is there. Status (3) is a pattern in which an emergency operation is started when the mobile phone 10 is powered off (battery voltage is less than or equal to the mobile device operation limit voltage Vl), and the mobile device internal circuit operation limit voltage Vc or higher even after the operation ends. It is. Status (4) is a pattern in which the mobile phone 10 starts emergency operation from a power-off state (battery voltage is less than or equal to the mobile device operation limit voltage Vl), and the battery voltage falls below the mobile device internal circuit operation limit voltage Vc during operation. It is. Status (5) is a pattern in which the emergency operation is started from the state in which the mobile phone 10 is powered off (the battery voltage is equal to or lower than the mobile device internal circuit operation limit voltage Vc), and the battery voltage is equal to or higher than the battery protection voltage Vp even after the operation ends It is. The status (6) is a pattern in which an emergency operation is started from the state where the mobile phone 10 is powered off (the battery voltage is equal to or less than the mobile device internal circuit operation limit voltage Vc), and the battery voltage falls below the battery protection voltage Vp during the operation. . Status (7) is a pattern in which an emergency operation is started from a state in which the mobile phone 10 is powered off (battery voltage is equal to or lower than the battery protection voltage Vp). Status (8) is that emergency operation is started when the mobile phone 10 is powered on (battery voltage is greater than the mobile device operation limit voltage Vl), and the battery voltage falls below the mobile device internal circuit operation limit voltage Vc during operation. It is a pattern. Status (9) is a pattern in which an emergency operation is started from a state in which the mobile phone 10 is powered on (battery voltage is greater than the mobile device operation limit voltage Vl), and the battery voltage falls below the battery protection voltage Vp during the operation. The status (10) is a pattern in which an emergency operation is started from a state in which the mobile phone 10 is powered off (battery voltage is equal to or less than the mobile device operation limit voltage Vl), and the battery voltage falls below the battery protection voltage Vp during the operation.

  As shown in FIG. 3, status (6), status (7), status (9), and status (10) are patterns in which the battery voltage falls below the battery protection voltage Vp during the operation, and are highly urgent. This pattern is used only in cases. Status (1), Status (2), Status (3), Status (4), Status (5), and Status (8) are patterns in which the battery voltage is equal to or higher than the battery protection voltage Vp even after the operation is completed. It is a pattern that can be used both when the urgency is high and when the urgency is low. That is, when the urgency is high, one of status (1) to status (10) is selected, and the selected status is status (6), status (7), status (9), status (10 ), The battery protection is canceled and an emergency operation is executed. On the other hand, when the urgency is low, any of status (1), status (2), status (3), status (4), status (5), and status (8) that does not release battery protection Select. As a pattern when the emergency level is low, in addition to not performing battery protection cancellation, operations other than battery protection cancellation (shutdown cancellation, boot, boost operation) are performed first regardless of subsequent user operations. A pattern that can be freely used up to the battery protection limit can also be used.

  The case of high urgency is used in emergency disasters that are life-threatening, such as emergency calls to the police (110) and firefighting (119), or the use of GPS to identify the location of the mobile phone 10 On the other hand, the case where the emergency level is low is assumed to be used when the user of the mobile phone 10 wants to make another call for business, for example. It is what you are doing.

  The power supply control unit 40 (FIG. 1) of the mobile phone 10 indicates the state of the battery 31 at the time when the emergency operation is started, the power consumption amount Wh necessary for the emergency operation to be performed, and the various information storage unit 25 for emergency operation. To execute the emergency operation control procedure.

  4 to 7 show various information (data sheet 1 to data sheet 4) stored in the emergency operation various information storage unit 25. FIG. As shown in FIG. 4, in the data sheet 1, the relationship between the battery voltage Vbt and the remaining capacity Wbt corresponding to the battery voltage Vbt is described for each emergency level described later. As shown in FIG. 5, the data sheet 2 describes the relationship between the content of the assumed emergency operation and the power consumption amount Wh consumed by the emergency operation. Further, as shown in FIG. 6, the data sheet 3 describes the relationship between the battery voltage Vbt at the time of starting the emergency operation and the battery voltage Vbt2 after the various emergency operations (power consumption amount Wh) are executed. ing. Further, as shown in FIG. 7, the data sheet 4 shows the relationship between the battery voltage Vbt at the start of the emergency operation and the battery voltage Vbt2 at the end of the emergency operation, corresponding status numbers ((1) to (10)). It is described with.

  The power supply control unit 40 of the mobile phone 10 is configured to provide information on the current state of the battery 31 (battery voltage Vbt) and the specified emergency operation (based on each data sheet stored in the various types of emergency operation information storage unit 25 ( For example, the content of the emergency action to be executed by the operation of the input unit 14 (specified by the user) (when the urgency is high (hereinafter referred to as “high emergency level”) or when the urgency is low (hereinafter referred to as urgent) The system of the mobile phone 10 is controlled according to the level)), and an operating environment in which the battery 31 does not fall below the battery protection voltage Vp is selected. In this operating environment, the emergency designated by the user Completing an action or an alternative emergency action to replace the emergency action and, if the emergency level is “high”, the battery protection voltage V It is also adapted to select the operating environment below.

  FIGS. 8 to 11 and FIGS. 13 to 16 are flowcharts showing processing procedures during an emergency operation of the mobile phone 10. In FIG. 8, the main control unit 11 of the mobile phone 10 determines whether or not there is an emergency operation instruction (input of information regarding emergency operation) via the input unit 14 or the like in step ST101. If a negative result is obtained in step ST101, this means that there is no emergency operation instruction from the user or the like, and that the emergency operation is not required, and the main control unit 11 performs the emergency operation. The process of step ST101 is repeated until an instruction is input.

  On the other hand, if an affirmative result is obtained in step ST101, this means that an emergency operation is instructed by the user or the like, and the emergency control is required. Moving from step ST101 to step ST102, the emergency level is confirmed. After confirming the emergency level, the main control unit 11 proceeds to step ST103, and senses (detects) the battery voltage Vbt of the battery pack 30 by the battery voltage detection unit 40b (FIG. 1). When detecting battery voltage Vbt, it is necessary to keep the current consumption constant. Therefore, in step ST103, the main control unit 11 detects the battery voltage Vbt after making a transition to a preset state such as a standby state in which the LCD screen or LED of the display unit 13 is turned off.

  Then, the main control unit 11 moves to step ST104, and from the data sheet 1 (FIG. 4) stored in the various types of emergency operation information storage unit 25 (FIG. 1), the current control unit 11 detected in step ST103 described above. The battery remaining capacity Wbt (data sheet 1) corresponding to the battery voltage Vbt of the battery 31 is acquired, and from the data sheet 2 (FIG. 5) stored in the various types of emergency operation information storage unit 25 (FIG. 1), In step ST101, the power consumption amount Wh corresponding to the emergency operation designated via the input unit 14 is acquired. For example, if the current battery voltage Vbt is 4.2 [V] and the content of the designated emergency operation is “10 minutes incoming / outgoing call to emergency destination, GPS position transmission and LCD standard lighting”, the main control unit 11 obtains the remaining battery capacity Wbt (= 750 [mAh]) corresponding to the case where the current battery voltage Vbt is 4.2 [V] from the data sheet 1 and the emergency operation “to the emergency destination” from the data sheet 2. The power consumption amount Wh (= 51.2 [mAh]) corresponding to “10 minutes outgoing / incoming call, GPS position transmission and LCD standard lighting” is acquired.

  Then, the main control unit 11 moves from step ST104 to step ST105 shown in FIG. 9, and determines the designated emergency level. When the emergency level “high” is designated, the main control unit 11 moves from step ST105 to step ST106 by obtaining an affirmative result in step ST105, and acquires the necessary power amount (power consumption) acquired in step ST104 described above. It is determined whether or not the amount Wh) is equal to or less than the remaining battery capacity Wbt acquired in step ST104 described above. If a positive result is obtained in step ST106, this means that the remaining battery capacity Wbt of the battery 31 is larger than the capacity necessary for executing the designated emergency operation, and the designated emergency operation can be completed. This means that the main control unit 11 moves from step ST106 to step ST107, and from the data sheet 3 and the data sheet 4 of the various types of emergency operation information storage unit 25, the statuses (1) to (10) Get one.

  For example, the battery voltage Vbt at the time of emergency operation start is 4.2 [V], and consumption corresponding to the contents of the designated emergency operation (for example, “10 minutes incoming and outgoing calls to the emergency destination, GPS position transmission and LCD standard lighting”) Assuming that the electric energy Wh is 51.2 [mAh], the main control unit 11 determines from the data sheet 3 that the battery voltage Vbt = 4.2 [V] and the consumed electric energy Wh = 51.2 [mAh] after the emergency operation. The battery voltage Vbt2 = 3.85 [V] is acquired. From the data sheet 4 (FIG. 7), the relationship between the battery voltage Vbt and the battery voltage Vbt2 after the emergency operation, the mobile device operation limit voltage Vl, the mobile device internal circuit operation limit voltage Vc, and the battery protection voltage Vp is satisfied. Select a status. In the present embodiment, as described above with reference to FIG. 2, the mobile device operation limit voltage Vl = 3.4 [V], the mobile device internal circuit operation limit voltage Vc = 2.9 [V], and the battery protection voltage Vp = 2.294 [V]. Therefore, for example, when the battery voltage Vbt = 4.2 [V] and the battery voltage Vbt2 after emergency operation V3.82 [V], the relationship of Vl <Vbt and Vl ≦ Vbt2 is established, and the main control unit 11 Select the status (1) corresponding to the relationship.

  If a negative result is obtained in step ST106 described above, this means that the power consumption (required power amount) Wh corresponding to the designated emergency operation is larger than the battery remaining capacity Wbt, that is, the battery remaining capacity Wbt. This means that the designated emergency operation cannot be completed, and the main control unit 11 moves from step ST106 to step ST108 to determine whether or not the user has set emergency operation priority in advance. Judging. The priority setting means a setting in which a user assigns a priority in advance to an assumed emergency operation. When this setting is made, the main control unit 11 displays the setting result as various information for emergency operation. Store in the storage unit 25. As a result, the main control unit 11 can determine whether or not emergency operation priority settings have been made by checking the emergency operation various information storage unit 25.

  If an affirmative result is obtained in step ST108, this means that the user has made emergency operation priority settings in advance, and the main control unit 11 moves from step ST108 to step ST109 and sets in advance. For the emergency action being performed, an emergency action having a priority lower than that of the emergency action designated at this time is selected, and the selection result is displayed on the display unit 13, and then the process proceeds to step ST107. In this way, by re-specifying the emergency operation with the lowered priority, for example, as shown in FIG. 5, if the power consumption amount Wh is set to be smaller as the priority is lowered, priority is given. By respecifying the emergency operation with a low degree, an emergency operation that falls within the remaining battery capacity Wbt is designated.

  On the other hand, when the user has not set emergency operation priority in advance, the main control unit 11 obtains a negative result in step ST108 described above, and moves from step ST108 to step ST110 to set the remaining battery capacity Wbt. On the other hand, an emergency action that can be completed is selected and displayed on the display unit 13. When the user approves the operation displayed on the display unit 13, the user inputs that fact via the input unit 14. Then, the main control unit 11 determines whether or not the user's approval has been obtained in step ST111. If the approval has not been obtained, the main control unit 11 proceeds from step ST111 to step ST112 and displays an error on the display unit 13. After the display, the processing procedure ends. On the other hand, when the approval by the user is obtained, the main control unit 11 moves from step ST111 to step ST107, and selects the status corresponding to the operation for which the approval is obtained from the data sheet 3 and the data sheet 4. . Thus, when the user has not set a priority for the emergency action in advance, an emergency action that can be completed is selected according to the remaining battery capacity Wbt.

  On the other hand, when a negative result is obtained in step ST105 described above, this means that the emergency level designated by the user is low, and the main control unit 11 moves from step ST105 to step ST113. Operations that can be performed without the battery falling below the battery protection voltage Vp are displayed on the display unit 13 (FIG. 1), and in subsequent step ST111, it is determined whether or not an approval by the user has been obtained. As described above, when the user selects an operation with a low emergency level, the user selects an emergency operation that can be executed by the current remaining battery capacity Wbt.

  When the status is selected in step ST107, the main control unit 11 proceeds from step ST107 to step ST114 shown in FIG. 10, and confirms the status selected in step ST107 described above. Here, if a negative result is obtained in the above-described step ST105, that is, if the emergency level is “low”, the operation is selected so that the battery does not fall below the battery protection voltage Vp. The status is one of statuses (1) to (5) and (8). When the emergency level is “low” and the main control unit 11 determines that the status (6), (7), (9), and (10) are satisfied, the display is made in ST113. Since there is no action that can be performed, the above-described ST111 user approval is not obtained, the process proceeds to ST112, an error is displayed on the display unit 13, and the processing procedure is terminated. When the selected status is status (1), the main control unit 11 moves from step ST114 to step ST115 in FIG. 10, and designates the emergency action designated at this time (the emergency action designated in step ST101 described above). Operation). When this emergency operation is completed, the process proceeds to step ST116, and after completing the emergency operation, all control operations are returned to defaults in step ST117, and then the processing procedure is terminated. As described above, when the remaining battery capacity Wbt is sufficient for the designated emergency operation (when it is predicted that the shutdown function by the mobile device operation limit voltage Vl does not work), the designated emergency operation is executed. Will be.

  On the other hand, when the status selected in step ST107 described above is other than status (1), the main control unit 11 proceeds from step ST114 to step ST118, and first, the shutdown function by the mobile unit operation limit voltage Vl. Disable. In this way, when it is predicted that the shutdown function by the mobile device operation limit voltage Vl will work during the emergency operation, the shutdown function is invalidated so that the operation is originally stopped by the shutdown function. However, control is performed so that the emergency operation can be continued without shutting down.

  Then, the main control unit 11 moves to step ST119 and executes processing (operation mode) according to the status selected in step ST107 described above. For example, when the selected status is any one of the statuses (3), (4), and (10), the main control unit 11 proceeds from step ST119 to step ST121 shown in FIG. (FIG. 1) acquires the low power consumption setting information from the emergency operation various information storage unit 25 (FIG. 1), and shifts to the low power consumption emergency operation mode.

  Here, FIG. 12 shows the low power consumption setting information acquired from the various types of emergency operation information storage unit 25 (FIG. 1), and this setting information includes each status (status (1) to status (10)). The definition is shown. The status definition is information indicating whether or not various operation modes in each status are necessary. The operation mode listed in this definition is an operation mode related to battery protection. In this embodiment, “shutdown cancel”, “emergency operation boot”, “boost”, “battery protection release”, “ “Continue monitoring battery voltage” is set. “Shutdown cancellation” is a function installed in the mobile phone 10 to stop the power supply to the system when the battery voltage falls below a certain value to prevent abnormal operation of the mobile device and protect the battery. This mode cancels the operation. “Emergency operation boot” is an operation mode for starting from a power-off state when the battery voltage is equal to or lower than the mobile device operation limit voltage. “Boost” is an operation mode for boosting the battery voltage and ensuring the operation of the internal circuit when the battery voltage may fall below the mobile device internal circuit operation limit voltage Vc. “Battery protection release” is an operation mode for authenticating the battery and canceling the control of the shut-off unit for the main control unit of the battery, and this operation mode is used only when the emergency level is “high”. . “Continue monitoring battery voltage” is executed when the battery voltage may fall below the mobile device internal circuit operation limit voltage Vc or the battery protection voltage Vp during emergency operation by continuously monitoring the battery voltage. Mode of operation.

  For example, status (1) indicates that the emergency operation is started from the state where the mobile phone 10 is powered on (battery voltage is higher than the mobile device operation limit voltage Vl), and the battery voltage remains at the mobile device operation limit voltage Vl after the operation ends. Due to the above pattern, no load beyond normal use is considered for the battery 31, and any operation mode for protecting the battery becomes unnecessary. On the other hand, for example, in the status (2), an emergency operation is started from a state in which the mobile phone 10 is powered on (battery voltage is higher than the mobile device operation limit voltage Vl), and the battery voltage is operated during the operation. It is a pattern below the limit voltage Vl. In this case, the emergency operation is started from the power-on state, so that the “emergency operation boot” operation is unnecessary, and the battery voltage is assumed to be lower than the mobile device operation limit voltage Vl. In order to continue, the “shutdown cancel” operation is required. In addition, since it is unlikely that the mobile device internal circuit operation limit voltage Vc falls below, the “boost” operation is unnecessary, and therefore the “continuous monitoring of battery voltage” operation is unnecessary even if the “shutdown cancel” operation is executed. Become.

  The status (3) indicates that the emergency operation is started when the mobile phone 10 is powered off (battery voltage is lower than the mobile device operation limit voltage Vl), and the mobile device internal circuit operation limit voltage Vc is higher than the mobile device internal circuit operation limit voltage Vc. It is a certain pattern. In this case, the emergency operation is started from the power-off state, so that the “emergency operation boot” operation is necessary, and the battery voltage becomes the emergency operation in a state of being lower than the mobile device operation limit voltage Vl. “Shutdown cancel” operation is required. In addition, since it is unlikely that the mobile device internal circuit operation limit voltage Vc falls below, the “boost” operation is unnecessary, and therefore the “continuous monitoring of battery voltage” operation is unnecessary even if the “shutdown cancel” operation is executed. Become.

  In status (4), emergency operation is started when the mobile phone 10 is powered off (battery voltage is less than or equal to the mobile device operation limit voltage Vl), and during operation, the battery voltage is set to the mobile device internal circuit operation limit voltage Vc. The pattern is below. In this case, the emergency operation is started from the power-off state, so that the “emergency operation boot” operation is necessary, and the battery voltage becomes the emergency operation in a state of being lower than the mobile device operation limit voltage Vl. The “shutdown cancel” operation is required, and further, the “boost” operation is required because the battery voltage may fall below the mobile device internal circuit operation limit voltage Vc. Since this “boost” operation is necessary when the battery voltage falls below the mobile device internal circuit operation limit voltage Vc, the “continue battery monitoring” operation is executed, and the battery voltage is applied to the mobile device internal circuit operation. When the vicinity of the limit voltage Vc is detected, the “boost” operation is performed. In this way, by performing the “boost” operation for the first time when the “boost” operation is necessary, it is possible to avoid a decrease in efficiency by performing the “boost” operation from the beginning.

  The status (5) indicates that the emergency operation is started when the mobile phone 10 is powered off (battery voltage is lower than the mobile device internal circuit operation limit voltage Vc), and the battery voltage remains at the battery protection voltage Vp or higher after the operation ends. It is a certain pattern. In this case, the emergency operation is started from the power-off state, so that the “emergency operation boot” operation is necessary, and the battery voltage becomes the emergency operation in a state of being lower than the mobile device operation limit voltage Vl. The “shutdown cancel” operation is required, and further, the “boost” operation is required due to the emergency operation in a state where the battery voltage falls below the mobile device internal circuit operation limit voltage Vc.

  Status (6) is a pattern in which the emergency operation is started from the state in which the mobile phone 10 is powered off (the battery voltage is equal to or less than the mobile device internal circuit operation limit voltage Vc), and the battery voltage falls below the battery protection voltage Vp during the operation. It is. In this case, an “emergency operation boot” operation is required by starting an emergency operation from a power-off state, and the battery voltage becomes an emergency operation in a state where the mobile device internal circuit operation limit voltage Vc is below. Thus, “shutdown cancellation” and “boost” operations are required. In addition, by performing the “Battery Protection Release” operation as necessary while performing the “Continue Monitoring Battery Voltage” operation, the battery voltage will only drop to a level that actually requires the protection release. The protection is released, and damage to the battery due to unnecessary protection release can be avoided.

  Status (7) is a pattern in which the mobile phone 10 starts an emergency operation from a power-off state (battery protection voltage Vp or less). In this case, the emergency operation is started in a state of the battery protection voltage Vp or less, so that the “boost” operation and the “battery protection release” operation are always required without performing the “continuous monitoring of the battery voltage” operation. It becomes. In addition, by starting emergency operation from the power-off state, an “emergency operation boot” operation is necessary, and the battery voltage becomes an emergency operation in a state of being lower than the mobile device operation limit voltage Vl. Naturally, a “shutdown cancel” operation is also required.

  In status (8), emergency operation is started when the mobile phone 10 is powered on (battery voltage is greater than the mobile device operation limit voltage Vl), and the battery voltage is changed to the mobile device internal circuit operation limit voltage Vc during operation. It is a pattern below. In this case, by starting the emergency operation from the power-on state, the “emergency operation boot” operation is unnecessary, and the battery voltage is lower than the mobile device operation limit voltage Vl (the boundary line of the mobile device operation limit power Vl). ) And lower than the mobile unit internal circuit operation limit voltage Vc in the middle (exceeding the boundary line of the mobile unit internal circuit operation limit voltage Vc). In addition, an operation of “continuously monitoring the battery voltage” is required for timing the “boost” operation. Note that the “battery protection release” operation is unnecessary because the battery voltage is assumed not to drop to the battery protection voltage Vp.

  Status (9) is a pattern in which an emergency operation is started when the mobile phone 10 is powered on (battery voltage is greater than the mobile device operation limit voltage Vl), and the battery voltage falls below the battery protection voltage Vp during the operation. is there. In this case, by starting the emergency operation from the power-on state, the “emergency operation boot” operation is unnecessary, and the battery voltage is assumed to be lower than the battery protection voltage Vp. An operation of “continuously monitoring the battery voltage” is required for the timing of the operation, “boost” operation, “battery protection release” operation, “boost” operation, and “battery protection release” operation.

  The status (10) is a pattern in which an emergency operation is started when the mobile phone 10 is powered off (battery voltage is less than or equal to the mobile device operation limit voltage Vl), and the battery voltage falls below the battery protection voltage Vp during the operation. is there. In this case, an “emergency operation boot” operation is required by starting an emergency operation from a power-off state, and the battery voltage is assumed to be lower than the battery protection voltage Vp. An operation of “continuously monitoring the battery voltage” is required for the timing of the operation, “boost” operation, “battery protection release” operation, “boost” operation, and “battery protection release” operation.

  As described above, based on the necessity / unnecessity of the operation mode in each status described with reference to FIG. 12, the main control unit 11 performs the emergency operation even when the battery voltage becomes the mobile device operation limit voltage Vl or less. Execute the operation mode using the battery.

  That is, when the operation mode is switched to the emergency operation mode in step ST121 of FIG. 11, the main control unit 11 moves to step ST122, and the boot control unit 22 makes an emergency operation with a small startup power from the emergency operation mode OS storage unit 24. Read and start the mode OS. In step ST123, an emergency operation is started. In step ST124, the status selected in step ST107 (FIG. 9) is confirmed.

  When the status (3) is selected, this means that the battery voltage Vbt does not fall below the mobile unit internal circuit operation limit voltage Vc, and the main control unit 11 moves from step ST124 to step ST125. Complete the emergency action. Then, after returning all control operations to the default, the processing procedure ends.

  On the other hand, if it is confirmed in step ST124 that the status selected at this time is either status (4) or status (10), the main control unit 11 performs steps ST124 to ST126. Then, the battery voltage detection unit 40b detects the battery voltage Vbt. In step ST127, the main control unit 11 determines whether or not the battery voltage Vbt ≦ the mobile device internal circuit operation limit voltage Vc. If a negative result is obtained in step ST127, this means that the battery voltage Vbt has not yet fallen below the mobile unit internal circuit operation limit voltage Vc, and the main control unit 11 proceeds to step ST126 described above. Returning, the detection of the battery voltage Vbt is continued.

  On the other hand, if a positive result is obtained in step ST127, this means that the battery voltage Vbt has fallen below the mobile device internal circuit operation limit voltage Vc, and the main controller 11 starts from step ST127. Moving to step ST128, the DC-DC booster 40a is turned on to boost the supplied power to the internal circuit operation limit voltage Vc or higher. As a result, the battery voltage Vbt, which is lower than the internal circuit operation limit voltage Vc, is boosted to the internal circuit operation limit voltage Vc and supplied to the system, so that the system operation stops halfway after the emergency operation is disclosed. Can be avoided.

  Then, in the subsequent step ST129, the main control unit 11 confirms the status selected in the above-described step ST107. When the status (4) is selected, this means that the battery voltage Vbt2 after the emergency operation does not fall below the battery protection voltage Vp, and the main control unit 11 moves to step ST125 and performs an emergency Complete the action. Then, after returning all control operations to the default, the processing procedure ends.

  On the other hand, when it is confirmed in step ST129 that the status selected at this time is status (10), the main control unit 11 moves from step ST129 to step ST131 shown in FIG. The battery voltage detection unit 40b detects the battery voltage Vbt. Then, in step ST132, main controller 11 determines whether or not battery voltage Vbt ≦ battery protection voltage Vp. If a negative result is obtained in step ST132, this means that the battery voltage Vbt has not yet fallen below the battery protection voltage Vp, and the main control unit 11 returns to step ST131 described above, and The detection of the voltage Vbt is continued.

  On the other hand, if a positive result is obtained in step ST132, this means that the battery voltage Vbt has fallen below the battery protection voltage Vp, and the main control unit 11 moves from step ST132 to step ST133. Thus, based on the value of the changeable remaining number counter 33 in the battery pack 30, it is determined whether or not the number of changes of the battery protection (shutoff) condition has reached a specified value, that is, whether there is a changeable remaining number. Here, the number of times the battery protection condition can be changed is the allowance for canceling the battery protection operation for protecting the battery by stopping the battery consumption by blocking the connection of the battery 31 by the blocking unit 36 (FIG. 1). This means the number of times (stored in the limit value data storage unit 32), and the changeable remaining number counter 33 is decremented each time the main control unit 35 of the battery pack 30 performs the battery protection release operation. In this way, the battery protection release history is held in the battery pack 30. When the number of times of release reaches the specified number, the subsequent battery protection cannot be released. For example, the remaining battery can be replaced once. By prompting, it is possible to avoid a situation in which an emergency call is not completed because battery protection cannot be canceled in an emergency.

  The battery protection is released by performing authentication using the authentication data 34 between the main control unit 11 and the main control unit 35 of the battery pack 30 and changing the blocking condition of the blocking unit 36 after the authentication is performed. It is executed by doing. That is, the main control unit 35 of the battery pack 30 authorizes the mobile phone 10 that is the power supply destination and permits the protection release. In this case, an authentication communication pin is added to the battery pack 30, and an authentication memory (authentication data 34) is provided in the battery pack 30. As the authentication method, plain text password / encrypted password (challenge response method using common key encryption) or the like is used. Examples of the authentication command include control value (restriction release) setting, default value (restriction release cancellation) setting, restriction value (restriction release) changeable remaining number inquiry, and the like. By enabling protection cancellation through authentication in this way, it is possible to ensure the possibility of battery use in an emergency, and it is difficult to intentionally cancel protection by a third device, thus ensuring safety. Can do. In the mobile phone 10, the decrement result of the changeable remaining number counter 33 may be displayed on the display unit 13 to notify the user of the battery state.

  If a negative result is obtained in step ST133, this means that the changeable remaining number determination is not OK, that is, the count value of the changeable remaining number counter 33 is “0”. The main control unit 11 moves from step ST133 to step ST134, displays an error on the display unit 13 (FIG. 1), moves to step ST139, completes the emergency operation, and defaults all control operations. Then, the processing procedure ends. As a result, when the number of cancellations of the battery protection operation reaches a predetermined number set in advance, the user is notified of the fact by an error display and the emergency operation is completed. Measures such as battery replacement can be taken.

  On the other hand, if an affirmative result is obtained in step ST133, this means that the number of times the battery protection operation has been released has not reached the predetermined number of times set in advance. Moving from ST133 to step ST135, the display unit 13 displays that the battery protection has been released within the specified number of times (wording display regarding safety). Then, the main control unit 11 moves to step ST136 and determines whether or not the user has approved the release of the battery protection. The user inputs whether or not to approve the release of the battery protection via the input unit 14 by looking at the display on the display unit 13 in step ST135. If the user does not approve the release of the battery protection, the main control unit 11 moves from step ST136 to step ST134, displays an error on the display unit 13 (FIG. 1), moves to step ST139, and performs an emergency operation. After completion and returning all control operations to the default, the processing procedure is terminated.

  On the other hand, when the user approves the cancellation of the battery protection, the main control unit 11 moves from step ST136 to step ST137, releases the battery protection, and then decrements the changeable remaining number counter 33 in step ST138. Then, the process proceeds to step ST139, the emergency operation is completed, and all control operations are returned to the default, and then the processing procedure is ended. Thus, when there is a possibility that the battery protection voltage Vp may be decreased, the battery protection is canceled as necessary while detecting the battery voltage Vbt, so that the use of the battery can be continued and the emergency operation can be completed. it can.

  On the other hand, if it is confirmed in step ST119 shown in FIG. 10 that status (2), status (8), or status (9) is selected, this indicates that the current battery voltage Vbt is the mobile unit operation. Although it is not lower than the limit voltage Vl, it means that there is a possibility that the mobile unit operation limit voltage Vl may be lowered during the emergency operation, and the main control unit 11 moves from step ST119 to step ST141 shown in FIG. After the emergency operation is started, the status is confirmed in the subsequent step ST142. Here, in the above-described step ST107, when the status (2) is selected, this means that the battery voltage Vbt2 after the emergency operation does not fall below the mobile device internal circuit operation limit voltage Vc. The main control unit 11 moves from step ST142 to step ST147, completes the emergency operation, returns all control operations to the default, and then ends the processing procedure.

  On the other hand, when it is confirmed in step ST142 that the status (8) or the status (9) is selected, this indicates that the battery voltage Vbt2 after the emergency operation is the mobile device internal circuit operation limit voltage Vc. The main control unit 11 moves from step ST142 to step ST143, and the battery voltage detection unit 40b detects the battery voltage Vbt. Then, in subsequent step ST144, it is determined whether or not Vbt ≦ Vc (mobile device internal circuit operation limit voltage) for battery voltage Vbt detected in step ST143 described above.

  If a negative result is obtained in step ST144, this means that the battery voltage Vbt has not yet fallen below the mobile device internal circuit operation limit voltage Vc, that is, the battery is continuously used without turning on the booster. The main control unit 11 returns to step ST143 and continues to detect the battery voltage Vbt. On the other hand, if an affirmative result is obtained in step ST144, this means that the battery voltage Vbt is lower than the mobile device internal circuit operation limit voltage Vc, and boosting is necessary. Moves from step ST144 to step ST145, turns on the DC-DC booster 40a, and boosts the supplied power to the internal circuit operation limit voltage Vc or higher. As a result, the battery voltage Vbt, which is lower than the internal circuit operation limit voltage Vc, is boosted to the internal circuit operation limit voltage Vc and supplied to the system, so that the system operation stops halfway after the emergency operation is disclosed. Can be avoided.

  Then, the main control unit 11 proceeds to subsequent step ST146 to confirm the status selected at this time. When the status (8) is selected, this means that the battery voltage Vbt2 after the emergency operation does not fall below the battery protection voltage Vp, and the main control unit 11 moves from step ST146 to step ST147. Then, the emergency operation is completed and all the control operations are returned to the default, and then the processing procedure ends.

  On the other hand, when it is confirmed in step ST146 that the status (9) is selected, this means that the battery voltage Vbt2 after the emergency operation is lower than the battery protection voltage Vp. The control unit 11 moves from step ST146 to step ST131 shown in FIG. 13, and executes the processes of steps ST131 to ST139. As a result, status (2), status (8), or status (9) is selected, and the battery voltage Vbt falls below the mobile unit operation limit voltage Vl during the emergency operation, and further falls below the battery protection voltage Vp. In the case (that is, when the status (9) is selected), the battery protection is released and the emergency operation is continued.

  On the other hand, if it is confirmed in step ST119 shown in FIG. 10 that the status (5) or status (6) is selected, this means that the current battery voltage Vbt becomes the mobile device internal circuit operation limit voltage Vc. The main control unit 11 moves from step ST119 to step ST151 shown in FIG. 15, turns on the DC-DC boosting unit 40a, and supplies power to the internal circuit operation limit voltage Vc or higher. Boost to. As a result, the battery voltage Vbt, which is lower than the internal circuit operation limit voltage Vc, is boosted to the internal circuit operation limit voltage Vc or higher and supplied to the system so that the system can be operated when the emergency operation is disclosed. Power can be supplied.

  Then, the main control unit 11 moves to step ST152, acquires the low power consumption setting information from the emergency operation mode information storage unit 25 (FIG. 1) by the emergency operation mode control unit 26 (FIG. 1), and reduces the low power consumption. Transition to emergency power operation mode. When the mode is switched to the emergency operation mode, the main control unit 11 moves to step ST153, and the boot control unit 22 reads out and starts the emergency operation mode OS with a small activation power from the emergency operation mode OS storage unit 24. Then, in step ST154, an emergency operation is started, and in the subsequent step ST155, the status selected in the above-described step ST107 (FIG. 9) is confirmed.

  When the status (5) is selected, this means that the battery voltage Vbt does not fall below the battery protection voltage Vp, and the main control unit 11 moves from step ST155 to step ST156 to perform emergency operation. To complete. Then, after returning all control operations to the default, the processing procedure ends.

  On the other hand, when it is confirmed in step ST155 that the status selected at this time is status (6), this means that the battery voltage Vbt falls below the battery protection voltage Vp during the emergency operation. The main control unit 11 moves from step ST155 to step ST131 shown in FIG. 13, and executes the processes of steps ST131 to ST139. Thereby, when the status (5) or the status (6) is selected and the battery voltage Vbt is lower than the mobile device internal operation limit voltage Vc at the start of the emergency operation, and further lower than the battery protection voltage Vp ( That is, when the status (6) is selected, the battery protection is released and the emergency operation is continued.

  On the other hand, when it is confirmed in step ST119 shown in FIG. 10 that the status (7) is selected, this means that the emergency level is “high” and the current battery voltage Vbt is the battery protection voltage. The main control unit 11 moves from step ST119 to step ST161 shown in FIG. 16 and performs battery protection (blocking) according to the value of the changeable remaining number counter 33 in the battery pack 30. It is determined whether or not the number of times of change in the condition (1) has reached a specified value, that is, whether there is a remaining number that can be changed.

  If a negative result is obtained in step ST161, this means that the changeable remaining number determination is not OK, that is, the count value of the changeable remaining number counter 33 is “0”. The main control unit 11 moves from step ST161 to step ST162, displays an error on the display unit 13 (FIG. 1), moves to step ST163, returns all control operations to default, and then performs the processing. End the procedure. Thereby, when the cancellation | release number of battery protection operation is the preset number of times set beforehand, the fact is notified to a user by an error display, and a process is complete | finished.

  On the other hand, if an affirmative result is obtained in step ST161, this means that the number of times the battery protection operation has been released has not reached the predetermined number of times set in advance. Moving from ST161 to step ST164, the display unit 13 displays that the battery protection is released within the specified number of times (a wording display regarding safety). Then, the main control unit 11 moves to step ST165 and determines whether or not the user has approved the release of the battery protection. The user inputs whether or not to approve the release of the battery protection via the input unit 14 by looking at the display on the display unit 13 in step ST164. If the user does not approve the release of the battery protection, the main control unit 11 moves from step ST165 to step ST162, displays an error on the display unit 13 (FIG. 1), moves to step ST163, and performs an emergency operation. After completion and returning all control operations to the default, the processing procedure is terminated.

  On the other hand, when the user approves the cancellation of the battery protection, the main control unit 11 moves from step ST165 to step ST166, releases the battery protection, and then decrements the changeable remaining number counter 33 in step ST167. Thereafter, the process proceeds to step ST151 shown in FIG. 15, and the same processing is executed in steps ST151 to ST155. In step ST155, when it is confirmed that the status (7) is selected, the process proceeds from step ST155 to step ST131 shown in FIG. 13, and the processes in steps ST131 to ST139 are executed. As a result, when the emergency level is “high” and the battery voltage Vbt at the start of the emergency operation is lower than the battery protection voltage Vp, the main control unit 11 defines the number of battery protection release times. The battery protection is canceled on the condition that the number of times has not been reached and the user's approval is obtained, and the emergency operation is executed by boosting the output of the battery.

  Next, the display contents of the display unit 13 in the emergency operation control processing procedure of the mobile phone 10 described above are shown in FIGS. As shown in FIG. 17, when the mobile phone 10 is in a standby state, a standby screen is displayed on the display unit 13 (ST201). When the emergency level confirmation process (step ST102 (FIG. 8)) is executed, an image for selecting the emergency level “high” or “low” is displayed on the display unit 13 (ST202). Choose one.

  When the emergency level “high” is selected (step ST105: YES (FIG. 9)), the battery voltage detection unit 40b detects the battery voltage Vbt, and the remaining capacity Wbt of the battery 31 from the data sheet 1 (FIG. 4). Further, the contents of the emergency operation and the power consumption amount (necessary power amount) Wh are obtained from the data sheet 2 (FIG. 5) (ST203). The contents of the emergency action are selected by the user's selection or in a preset priority order.

  From these pieces of information, the emergency operation priority control algorithm is executed (ST204), and when the required power amount ≦ the remaining capacity, the minimum and optimum control operation necessary for completing the emergency operation is executed ( ST206). In this control operation, the battery voltage Vbt2 after the emergency operation corresponding to the content of the selected emergency operation is obtained from the data sheet 3 (FIG. 6), and the current battery voltage Vbt, the battery voltage Vbt2 after the emergency operation, A status is selected from the data sheet 4 (FIG. 7) based on the mobile device operation limit voltage Vl, the mobile device internal circuit operation limit voltage Vc, and the battery protection voltage Vp set in the telephone 10 (step ST107 (FIG. 9). )). Based on these pieces of information, an emergency operation (FIGS. 10 to 16) is executed (ST207).

  On the other hand, in the emergency operation priority control algorithm (ST204), when the required power amount> the remaining capacity of the battery and the priority order of the emergency operation is set in advance (step ST108: YES (FIG. 9)), an emergency action with a lower priority is selected from the data sheet 2 and displayed on the display unit 13 (ST205). Then, the priority control algorithm (ST204) of the emergency action is executed again with the displayed emergency action content with the low priority, and the necessary power amount ≦ the emergency action with the low priority (that is, the low power consumption amount) ≦ When the remaining capacity is satisfied, the control operation is executed (ST206).

  On the other hand, when the required power amount> the remaining capacity of the battery and the priority order of the emergency operation is not set in advance (step ST108: NO (FIG. 9)), the emergency operation that can be completed is performed. It is selected and displayed on the display unit 13 (ST208). If the user's consent is obtained with this content, the control operation is executed (ST206). If the user's consent is not obtained, the execution of the emergency operation is canceled (ST209).

  On the other hand, when the emergency level selection screen is displayed on the display unit 13 (ST202), when the emergency level “low” is selected (step ST105: NO (FIG. 9)), as shown in FIG. When the remaining capacity is insufficient, the display unit 13 displays “no remaining battery power” and cancels the emergency operation (ST211). If the remaining capacity of the battery is present, the content of the emergency operation that can be completed with the remaining capacity is displayed on the display unit 13 (ST212). If the user's approval is obtained from the content, the emergency operation is performed. Is displayed (ST213). On the other hand, if the user's consent is not obtained, a message indicating that execution is to be stopped is displayed on the display unit 13 (ST214).

  As described above, in the mobile phone 10 according to the present embodiment, it is determined whether or not the input (or preset) emergency operation can be completed from the remaining battery capacity and the required power amount. If it can be completed, the emergency operation can be surely completed by executing it in an operating environment where the emergency operation can be completed. This avoids inconveniences such as an emergency operation being stopped midway. In addition, when the emergency action cannot be completed, an alternative emergency action that can be completed is presented. As a result, if it is determined that there is no guarantee that the selected emergency operation will be completed by the remaining battery capacity at that time, another means will be presented as the emergency operation, and the emergency operation will be stopped halfway. Inconvenience in an emergency is avoided.

  Further, even when an emergency operation has already been performed, even if a situation occurs in which the battery voltage Vbt falls below the mobile device operation limit voltage Vl, the mobile device internal circuit operation limit voltage Vc, or the battery protection voltage Vp, The possibility is recognized based on the status in advance, and the emergency operation is controlled before the emergency operation is stopped. This avoids inconveniences such as an emergency operation being stopped midway.

  In addition, since an emergency operation is started in accordance with the remaining battery capacity even at the time of shutdown, an inconvenience in an emergency such that no emergency operation is executed is avoided.

  Also, depending on the status, whether or not the emergency operation can be completed based on the remaining battery capacity and the amount of power required for the emergency operation, and control (such as disabling shutdown and canceling battery protection) By making the selection, it becomes unnecessary to constantly monitor the battery voltage, and it becomes possible to uniquely determine the control necessary for completing the emergency operation based on the status.

  Thus, according to the mobile phone 10 of the present embodiment, an emergency operation can be completed by selecting an operation environment and an emergency operation that can be completed in an emergency.

  In the above-described embodiment, the emergency operation stored in the emergency operation mode OS storage unit 24 when the mobile phone 10 is turned off to perform an emergency operation when the power is off. The case where the boot control unit 22 executes the mode OS to start up with low power consumption for emergency operation has been described, but the present invention is not limited to this, for example, the emergency operation mode OS A method of reducing the power consumption by slowing down the operation speed of the main control unit 11 may be used.

  Further, when the battery voltage is detected from the battery voltage detection unit 40, the approximate battery deterioration level is uniquely determined from the response time until the battery voltage rises to the specified value due to charging, and the predetermined deterioration level is obtained. By using the fact that the corresponding discharge curve is uniquely associated, the information on the available power amount in the emergency operation information storage unit 25 is automatically corrected from the most recent usage information every time the battery is charged.
