In addition to the recording medium, an operation peculiar to the present embodiment can be executed using a program / data supplied externally via a transmission medium.

4 and 5 are flowcharts showing an outline of the overall operation of the contactless charging apparatus 1.
First, on the contactless charging device 1 side, when the power-on operation by the power switch 17a is performed on the charging control unit 11 (YES in step A1 in FIG. 4), which electronic device 2 is placed? Is detected (step A2), and it waits until the electronic device 2 is placed. However, when even one electronic device 2 is placed (YES in step A2), it waits for the operation of the charging start switch 17b. (Step A3). Although not shown in the drawing, this flowchart is terminated when a power-off operation is performed by the power switch 17a, but when it is detected that even one electronic device 2 is not mounted. You may make it complete | finish, and the method of the completion | finish is arbitrary.

  Here, when the charging start switch 17b is operated to start charging (YES in step A3), after all the electronic devices 2 currently placed are requested to transmit device information (step A4). ), Device identification information (device ID, device name, etc.), charging specification information (information indicating whether or not the electronic device 2 is compatible with batch charging), presence / absence of reception function as device information from all the electronic devices 2 Information (information indicating whether or not a reception function is provided) is received and acquired (step A5). And with reference to each acquired charging specification information, all the electronic devices 2 currently mounted correspond to collective charging, that is, are electronic devices 2 corresponding to the non-contact charging method. (Step A6).

  If at least one electronic device 2 does not support batch charging among all the electronic devices 2 placed now (NO in step A6), for example, if the electronic device 2 is not removed, Notification (informing and transmitting) that charging cannot be started (step A7). In this case, an electronic device 2 that does not support batch charging is identified and device identification information (device ID, device name) as the device information is displayed on the display unit 16 for notification or an alarm sound is generated. Information is sent to the electronic device 2 via the non-contact communication unit 14 to the effect that batch charging is not supported.

  Then, it is checked whether or not the mounting status of the electronic device 2 is changed within a predetermined time (for example, 10 seconds) (step A8). If there is no change in the mounting status within the predetermined time (YES in step A8), In order to invalidate the operation of the current charging start switch 17b, the process returns to the above-described step A2, but when the placement situation changes due to the removal of the electronic device 2 that does not support batch charging (step A8). NO), returning to the above-mentioned step A4, requesting transmission of device information to all the electronic devices 2 currently mounted, then device identification information and charging as device information from all the electronic devices 2 The specification information is reacquired (step A5).

  When all the electronic devices 2 currently mounted support batch charging (YES in step A6), the electronic devices 2 are requested to transmit the remaining battery power (step A9). The battery remaining amount is received and acquired from each electronic device 2 (step A10), and each acquired battery remaining amount is equal to or greater than a predetermined threshold (1) (for example, full charge: 100% charge), that is, the threshold (1 It is checked whether or not the above electronic device 2 is present (step A11). Here, if there is an electronic device 2 having a remaining battery level equal to or greater than the threshold (1) (YES in step A11), the electronic device 2 is notified of an instruction not to accept charging (step A12). That is, an instruction to suppress charging acceptance is transmitted to the electronic device 2, device identification information of the electronic device 2 is displayed on the display unit 16, and an alarm sound is generated. In this case, the user may confirm the display of the device identification information and remove the electronic device 2 from the contactless charging apparatus 1 or may leave it as it is.

  Then, in the next step A13, it is checked whether each battery remaining amount is less than the threshold (1), that is, whether there is an electronic device 2 less than the threshold (1), and there is no electronic device 2 less than the threshold (1). 4 (NO in step A13), the process moves to step A14 in FIG. 4 to check whether charging is in progress. However, since it is before the start of charging (YES in step A14), all the currently mounted electrons are Notify that charging is not started because the remaining battery level of the device 2 is equal to or greater than the threshold (1) (step A15). In this case, for example, all the electronic devices 2 are notified by displaying on the display unit 16 that the charging is not started due to full charge, or an alarm sound is generated. Then, in order to invalidate the operation of the current charging start switch 17b, the process returns to step A2 in FIG.

  If there is an electronic device 2 having a remaining battery level less than the threshold (1) (YES in step A13 in FIG. 4), it is further checked whether there is an electronic device 2 having a remaining battery level equal to or less than the threshold (2) ( Step A17). Here, there is a relationship of threshold value (1)> threshold value (2), and threshold value (2) is, for example, a value just before the remaining battery level is 0 (zero). If there is at least one electronic device 2 whose remaining battery level is equal to or less than the threshold value (2) (YES in step A17), after energizing the charging primary coil 13a constituting the batch charging unit 1b, Therefore, a quick charging instruction is given to the charging switching unit 13b in the charging circuit unit 13 to switch to a state in which rapid charging is possible and to start rapid charging, and to display that the quick charging is being performed on the display unit 16 (Step A18).

  After starting the quick charge in this way, the charge control unit 11 checks whether or not the battery remaining amount acquisition timing generated by the time measuring unit 15 has been reached (step A19). For example, when the remaining battery level is acquired at intervals of one minute, the standby state is reached until the remaining battery level acquisition timing is reached while checking whether one minute has elapsed since the previous acquisition, but when the acquired timing is reached (step A19) And YES), the process returns to step A9 described above, and a request for transmission of the remaining battery level is sent to each electronic device 2. Then, the remaining battery level from each electronic device 2 is received and acquired (step A10), and it is checked whether the remaining battery level is greater than or equal to the threshold value (1) (step A11), and whether it is equal to or less than the threshold value (2). (Step A17).

  Here, when the remaining battery level of all the electronic devices 2 is equal to or greater than the threshold value (1) during the quick charge (NO in step A13), the process proceeds to step A14 in FIG. 4, but is currently being charged ( In step A14, NO), it is notified that the remaining battery level of all the electronic devices 2 currently mounted has reached the threshold value (1) or more, and charging is stopped (step A16). In this case, for example, the display unit 16 displays a notification that all the devices are fully charged, generates an alarm sound, and instructs the charge switching unit 13b in the charging circuit unit 13 to charge off. To stop charging. And it returns to step A2 of FIG.

  On the other hand, if there is no electronic device 2 whose remaining battery level is equal to or less than the threshold value (2) among the electronic devices 2 currently mounted, that is, if there is no device that requires emergency charging (see FIG. 4). In step A17, NO), it is checked whether or not the electronic device 2 having a receiving function is placed (step A20). That is, at the time of charging operation, there is a problem that noise generated by charging adversely affects the reception function of the electronic device 2 and lowers the reception sensitivity. However, the electronic device 2 having the reception function is contactless. If it is not placed on the charging device 1 (YES in step A20), there is no adverse effect on the reception function even if charging is started. Therefore, the process proceeds to step A18 described above, and quick charging is started, and the display unit 16 is displayed. Display that quick charging is in progress.

  In addition, the electronic device 2 whose battery remaining amount is equal to or less than the threshold (2), that is, the device that requires emergency charging is not placed (NO in step A17), and the electronic device 2 having a receiving function is placed. 5 (NO in step A20), the process proceeds to step A21 in FIG. 5 to request each electronic device 2 to transmit reception sensitivity, and receive and acquire the reception sensitivity from each electronic device 2 (step A22). ), The worst receiving sensitivity is specified from among them (step A23), and charging is performed at a charging speed corresponding to the receiving sensitivity (step A24). That is, as shown in FIG. 3, if the worst receiving sensitivity is less than the threshold value (a), normal charging (low speed charging) is performed, and if it is equal to or higher than the threshold value (a), rapid charging (high speed charging) is performed. Do.

  Then, each electronic device 2 is requested to transmit the remaining battery level (step A25), the remaining battery level is received from each electronic device 2 (step A26), and the acquired remaining battery level is a predetermined threshold value. (1) Whether the electronic device 2 is equal to or greater than (for example, full charge), that is, the electronic device 2 equal to or greater than the threshold (1) is checked (step A27). If an electronic device 2 having a remaining battery level equal to or greater than the threshold (1) is placed (YES in step A27), an instruction not to accept charging is sent to the electronic device 2 (step A28). ). In this case, an instruction to suppress charging acceptance is transmitted to the electronic device 2, the device identification information of the electronic device 2 is displayed on the display unit 16, and an alarm sound is generated. In this case, the user may confirm the display of the device identification information and remove the electronic device 2 from the contactless charging apparatus 1 or may leave it as it is.

  Then, in the next step A29, it is checked whether each battery remaining amount is less than the threshold value (1), that is, whether the electronic device 2 less than the threshold value (1) is mounted, and the remaining battery amount is the threshold value (1). If less than 2 electronic devices 2 are mounted (YES in step A29), it is checked whether or not the battery remaining amount acquisition timing generated by the time measuring unit 15 has been reached (step A30). For example, it is checked whether 1 minute has passed and the process returns to step A24 described above until the remaining battery charge acquisition timing is reached, and charging is continued at a speed corresponding to the current reception sensitivity. (YES in step A30), the process returns to the above-described step A21, makes a transmission request for reception sensitivity to each electronic device 2, acquires the reception sensitivity from each electronic device 2, and specifies the worst reception sensitivity. Then, charging is performed at a speed corresponding to them (steps A22 to A24).

  If there is no electronic device 2 whose remaining battery level is less than the threshold (1) due to such charging (NO in step A29), the remaining battery level of all electronic devices 2 currently mounted is equal to or higher than the threshold (1). Therefore, it is notified that all the electronic devices 2 have reached full charge, and charging is stopped (step A31). In this case, for example, the display unit 16 displays a notification that all the devices are fully charged, generates an alarm sound, and instructs the charge switching unit 13b in the charging circuit unit 13 to charge off. To stop charging. And it returns to step A2 of FIG.

FIG. 6 is a flowchart showing a characteristic operation on the electronic device 2 side that is started in response to detection of placement on the contactless charging apparatus 1.
First, when the central control unit 21 receives a device information transmission request from the contactless charging device 1 in a state where it is detected that the device is placed on the contactless charging device 1 (step B1), the storage unit The device identification information, the charging specification information, and the presence / absence information of the receiving function are read out and acquired from within 23 (step B2) and transmitted to the contactless charging apparatus 1 (step B3). Further, when information indicating that batch charging is not supported from the non-contact charging device 1 (YES in step B4), the fact is notified by a message display or an alarm sound (step B5). Further, when the battery remaining amount transmission request is received from the non-contact charging device 1 (YES in Step B6), the battery remaining amount (%) is detected and acquired with reference to the battery voltage detecting unit 22c (Step B7). It transmits with respect to the contact charging device 1 (step B8).

  When a charge acceptance suppression instruction is received from the contactless charging apparatus 1 (YES in step B9), an off switching signal is given to the charge control unit 22d to switch to a charge off state (charge acceptance suppression state) (step S9). B10). As a result, the reception of power energy from the contactless charging device 1 is suppressed, and the secondary battery 22a cannot be charged. And it is alert | reported by a message display or an alarm sound that it is a charge-off state (step B11). When the transmission request for the reception sensitivity is received from the contactless charging device 1 (YES in Step B12), the central control unit 21 detects and acquires the reception sensitivity from the reception sensitivity detection unit 25a (Step B13), It transmits to the charging device 1 (step B14). Thereafter, it is checked whether or not the contactless charging device 1 has been removed (the placement has been released) (step B15). If it is still placed (NO in step B15), the process returns to the above-described step B1, but the placement is continued. Is released from the non-contact charging device 1 to release (YES in step B15), this flow ends, and the flow returns to the main flow (not shown) of the electronic device 2.

  As described above, in the first embodiment, when the contactless charging apparatus 1 performs batch charging for a plurality of electronic devices 2, the electronic devices are collectively charged based on the device information acquired for each electronic device 2. If all of the electronic devices 2 support batch charging as a result, batch charging is performed, but if any of the electronic devices 2 does not support batch charging, Since the electronic device 2 is specified and notified, the user can know the electronic device 2 that does not support batch charging, and by removing the electronic device 2, batch charging can be performed. It can be carried out. As a result, it is possible to realize appropriate batch charging, which is highly practical.

  The non-contact charging device 1 can be configured not to perform batch charging for safety unless any of the electronic devices 2 supports batch charging.

  Since the contactless charging apparatus 1 acquires the device information of the electronic device 2 when the electronic device 2 is placed, the device information can be acquired when necessary. Power saving can be achieved.

  Since the contactless charging apparatus 1 re-acquires device information of the electronic device 2 when the mounting state of the electronic device 2 is changed, the electronic device 2 that does not support batch charging is removed. It is possible to efficiently determine whether or not all the electronic devices 2 are compatible with batch charging while saving power associated with acquisition of device information.

  Since the contactless charging apparatus 1 is configured to instruct the electronic device 2 to suppress collective charging if the remaining battery level of the electronic device 2 is equal to or greater than a predetermined threshold value, for example, the predetermined threshold value or greater. Even if a fully charged electronic device 2 is present (even if it is placed), it is possible to safely perform batch charging.

  Since the contactless charging apparatus 1 specifies and notifies the electronic device 2 when the remaining battery level of the electronic device 2 is equal to or greater than a predetermined threshold, the electronic device 2 is fully charged to the user. The device 2 can be notified, and it becomes possible to start using the device immediately, and it is useful for preventing overcharge.

  Since the contactless charging apparatus 1 stops the collective charging if the remaining battery level of all the electronic devices 2 is equal to or greater than a predetermined threshold, the collective charging can be stopped at an appropriate timing, thereby saving power. It helps to prevent overcharging while reducing the power consumption.

  The contactless charging apparatus 1 performs batch charging at a speed corresponding to the remaining battery level of each electronic device 2 when all the electronic devices 2 support batch charging. Rapid charging can be performed when there is a shortage, and it is possible to cope with a case where the user wants to start using the electronic device 2 immediately, and appropriate charging is possible.

  Since the contactless charging apparatus 1 performs batch charging at a speed corresponding to the remaining battery level of each electronic device 2, for example, if there is an electronic device in which the remaining battery level is near zero and quick charging is required , It is possible to perform batch charging according to the device.

  Since the contactless charging device 1 performs the batch charging by determining the charging speed based on the reception sensitivity of each electronic device 2 when all the electronic devices 2 support the batch charging, the charging operation It is possible to avoid as much as possible a situation in which noise that occurs sometimes adversely affects the reception of the electronic device 2 and reduces the reception sensitivity.

  Since the contactless charging device 1 performs batch charging at a charging speed corresponding to the electronic device having the worst receiving sensitivity among the receiving sensitivities for each electronic device 2, it is adapted to the electronic devices that are easily affected by charging. Batch charging can be performed at a speed.

  Since the contactless charging apparatus 1 periodically acquires the device information for each electronic device 2 and periodically controls the collective charging, the contactless charging device 1 performs suitable control over time and saves the control. Electricity can be achieved.

  When the electronic device 2 transmits its own device information to the contactless charging device 1, and in response thereto, the contactless charging device 1 side is notified that the electronic device 2 does not support batch charging. For example, when the user places the electronic device 2 on the contactless charging device 1, the user immediately determines whether the device is compatible with batch charging. It is possible to know, and by simply removing the electronic device 2 other than the corresponding device from the charging target, it is possible to appropriately charge the plurality of other electronic devices 2 at once, which is highly practical.

  In the above-described one embodiment, two types of charging speeds, normal charging and quick charging, are exemplified. However, referring to the reception sensitivity-charging speed table TBL shown in FIG. Either may be selected. This reception sensitivity-charging speed table TBL is provided in the storage unit 12, and is referred to when changing the charging speed according to the reception sensitivity of the call function when charging the electronic device 2, as shown in FIG. Table has items of “reception sensitivity” and “charge rate”. In the illustrated example, “reception sensitivity” stores “less than threshold (a1)” having the lowest reception sensitivity to “more than threshold (a3)” having the highest reception sensitivity. The “charging speed” stores the slowest “charging speed (1)” corresponding to “less than threshold (a1)” having the lowest receiving sensitivity, and “threshold (a3) having the highest receiving sensitivity. Corresponding to “above”, the fastest “charging speed (4)” is stored.

  On the other hand, as the “reception sensitivity”, the next worst “threshold (a1) or more and less than threshold (a2)” is stored, and the reception sensitivity is “threshold (a3) or more”. “Next to“ threshold (a2) or more and less than threshold (a3) ”is stored. The “charging speed” corresponds to “threshold (a1) or more and less than threshold (a2)” with the next lowest reception sensitivity, and “charging speed (2)” next to “charging speed (1)”. Is stored, and “charging speed (3)” next to “charging speed (4)” is stored corresponding to “threshold (a2) or more and less than threshold (a3)” having the next highest receiving sensitivity. ing.

FIG. 8 is a diagram showing how the charging speed is switched according to the receiving sensitivity with reference to the receiving sensitivity-charging speed table TBL of FIG.
FIG. 8 is a graph in which the horizontal axis corresponds to the reception sensitivity and the vertical axis corresponds to the charging speed. The predetermined points on the reception sensitivity are threshold values (a1), (a2), and (a3) for switching the charging speed. It is shown that. The illustrated example indicates that charging is performed at “charging speed (1)” when “reception sensitivity” is “less than threshold (a1)”, and “not less than threshold (a1) and less than threshold (a2)”. In this case, it indicates that charging is performed at “charging speed (2)”, and when “threshold (a2) is less than threshold (a3)”, charging is performed at “charging speed (3)”. In the case of “threshold (a3) or more”, it indicates that charging is performed at “charging speed (4)”. In this case, the charge switching unit 13b performs “charging speed (1)”, “charging speed (2)”, “charging speed (3)”, “charging speed (4)”, “charging off” according to the reception sensitivity. A configuration that can be switched to is sufficient.

  As described above, if any one of the four charging speeds is selected according to the reception sensitivity, appropriate charging control in consideration of the balance between the influence on reception and the charging time can be realized. Fine charge control is possible.

  In addition, it is limited to the case where the charging speed is controlled in 4 stages, and it is controlled in multiple stages (for example, 6 stages, 8 stages, 10 stages, etc.) of 4 stages or more according to the reception sensitivity, You may make it do. For example, as shown in FIG. 9, the charging speed may be changed smoothly in a curve while sequentially following the change in reception sensitivity. In this way, by making the charging speed follow the change in the reception sensitivity in a curved line, the charging control can be performed more finely.

  In the first embodiment described above, there is no electronic device 2 whose remaining battery level is equal to or less than the threshold value (2) among the electronic devices 2 currently mounted (NO in step A17 in FIG. 4). If no electronic device 2 having a receiving function is placed among the electronic devices 2 being used (YES in step A20), there is no adverse effect on the receiving function even if charging is started. Although rapid charging is started, normal charging may be started instead of rapid charging in order to save power during charging. Even when normal charging is started in this way, it is determined whether or not the remaining battery charge acquisition timing has been reached, and when the remaining battery charge acquisition timing is reached, the process returns to step A9 described above.

(Embodiment 2)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
In the first embodiment described above, the contactless charging apparatus 1 starts batch charging if all of the electronic devices 2 support batch charging, and any one of the electronic devices 2 supports batch charging. Otherwise, the electronic device 2 is specified and notified, but in this second embodiment, if any of the electronic devices 2 does not support batch charging, the electronic device 2 is used to suppress charging. An instruction related to charge control is transmitted to the device 2. Here, in both the embodiments, the same or the same names are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 10 is a flowchart showing an outline of the overall operation of the contactless charging apparatus 11 in the second embodiment.
First, similarly to the first embodiment described above, the contactless charging device 11 acquires device information according to the placement of the electronic device 2. That is, when the power is turned on by operating the power switch 17a (YES in step C1), the charging control unit 11 detects which electronic device 2 is placed (step C2), and the electronic device If at least one unit 2 is placed (YES in step C2), the operation waits for the charging start switch 17b (step C3). Here, when the charging start switch 17b is operated to start charging (YES in step C3), the charging primary coil 13a constituting the batch charging unit 1b is energized to start batch charging (step C4). . After charging is started in this manner, transmission of device information is requested to all electronic devices 2 currently mounted (step C5), and device information is transmitted from all the electronic devices 2 as device information. Identification information and charging specification information are received and acquired (step C6).

  And with reference to each acquired charging specification information, all the electronic devices 2 currently mounted correspond to collective charging, that is, are electronic devices 2 corresponding to the non-contact charging method. Whether or not (step C7). As a result, if at least one electronic device 2 among the plurality of mounted electronic devices 2 does not support batch charging (NO in step C7), the electronic device 2 that does not support batch charging. In order to display the device identification information (device ID, device name) on the display unit 16 for notification, generate an alarm sound, and notify the electronic device 2 not to accept charging. An acceptance suppression instruction is transmitted (step C8).

  Next, of all the electronic devices 2 that are currently mounted, each electronic device 2 that supports batch charging is requested to transmit the remaining battery power (step C9). The battery remaining amount is received and acquired (step C10), and each battery remaining amount is not less than a predetermined threshold (1) (for example, not less than full charge), that is, the electronic device 2 having the threshold (1) or more is placed. (Step C11). Here, if an electronic device 2 having a remaining battery level equal to or greater than the threshold value (1) is placed (YES in step C11), the acceptance suppression is performed to instruct the electronic device 2 not to accept charging. An instruction is transmitted, the device identification information of the electronic device 2 is displayed on the display unit 16 for notification, or an alarm sound is generated (step C12).

  And it is investigated whether the electronic device 2 with a battery remaining amount less than a threshold value (1) is mounted (step C13), and if the electronic device 2 with a battery remaining amount less than a threshold value (1) is not mounted by charging, (NO in step C13), since the remaining battery level of all electronic devices 2 currently mounted is greater than or equal to the threshold value (1), it is indicated that all the electronic devices 2 have reached the threshold value (1) or more. 16 is displayed and notified, and the charge switching unit 13b in the charging circuit unit 13 is instructed to be turned off by stopping the charging (step C14), and then the process returns to the above-described step C2. If the electronic device 2 having a remaining battery level less than the threshold (1) is placed (YES in step C13), the remaining battery level acquisition timing generated by the time measuring unit 15 is reached in order to continue charging. (Step C15), the process returns to Step C9 described above until the battery remaining amount acquisition timing is reached.

FIG. 11 is a flowchart illustrating a characteristic operation on the electronic device 2 side that is started in response to detection of placement on the contactless charging device 1 in the second embodiment.
First, when the central control unit 21 receives a device information transmission request from the contactless charging device 1 in a state where it is detected that the device is placed on the contactless charging device 1 (step D1), the storage unit The device identification information, the charging specification information, and the presence / absence information of the receiving function are read out and acquired from within 23 (step D2) and transmitted to the contactless charging apparatus 1 (step D3). Moreover, when the instruction | indication suppression suppression of charge reception is received from the non-contact charging device 1 (it is YES at step D4), an OFF switching signal is given with respect to the charge control part 22d, and it switches to a charge OFF state (charge reception suppression state). (Step D5). As a result, the reception of power energy from the contactless charging device 1 is suppressed, and the secondary battery 22a cannot be charged. And it is alert | reported by a message display or an alarm sound that it is a charge-off state (step D6).

  When the battery remaining amount transmission request is received from the non-contact charging device 1 (YES in step D8), the battery remaining amount (%) is detected and acquired with reference to the battery voltage detecting unit 22c (step D9). It transmits to the non-contact charging device 1 (step D9). Thereafter, it is checked whether or not the contactless charging device 1 has been removed (step D10), and if it is placed (NO in step D10), the process returns to the above-described step D1, but the contactless charging device is used to release the placement.

It is determined whether or not the electronic device 2 is compatible with batch charging. If the electronic device 2 is not compatible with batch charging, an instruction regarding charge control is transmitted to the electronic device 2 in order to suppress charging.

Since charging is suppressed in response to this instruction when it is received, batch charging is possible even if the electronic device 2 does not support batch charging (even when it is still mounted on the contactless charging device 1). Can be continued as it is without adversely affecting the battery, and by realizing appropriate collective charging, it becomes practical.

  Since the electronic device 2 transmits the battery remaining amount to the contactless charging device 11, the contactless charging device 1 side can control charging according to the battery remaining amount.

  In each of the above-described embodiments, the contactless charging apparatus 1 transmits an instruction related to charge control to the electronic device 2 if the remaining battery level of the electronic device 2 is a full charge that is equal to or greater than a predetermined threshold. However, a charging stop function may be provided on the electronic device 2 side. In other words, the electronic device 2 detects whether or not the battery level of the electronic device 2 is fully charged equal to or greater than a predetermined threshold value. The charging may be stopped by switching to the off state. In this case, the contactless charging apparatus 1 may be notified that charging has been stopped.

However, the connection may be detected using, for example, an electromagnetic induction action. In this case, you may make it detect that the electronic device 2 was mounted in the non-contact charging device 1 by whether the electromotive force generated by the electromagnetic induction action was larger than a predetermined value.

  In each of the above-described embodiments, the remaining battery level is acquired based on the battery voltage, but may be acquired by another method (algorithm).
