Description

  The present invention relates to a mobile device, a mobile device charge control method, a charge control program, and a program recording medium.

  A lithium ion battery or the like is used for a battery of a recent portable device, and the charge controller needs to be controlled by the charge controller. Even when such a portable device is connected to the charger, the battery is not always charged, but the state of charge is controlled in consideration of the remaining battery level. Here, in general, charging is started when the mobile device is connected to the charger, and charging is completed when the mobile device is fully charged. After that, the portable device operates with the power from the battery or the charger, but when operating with the power from the battery, it is determined in advance even if the portable device is connected to the charger. The charging operation is not started again unless power exceeding a certain threshold is consumed.

  When the mobile device operates with power from the battery, it is charged like this, so once charging is complete, it is essentially the same as when the mobile device is removed from the charger, and charging is complete Later, it is well known that the result is that the usable time that can be carried and used as a portable device has been shortened by the amount of battery power consumed before it is removed from the charger. It has been. It is desirable for the user to be able to carry and use the portable device that has been fully charged from the charger for the longest time, and the above-described situation is undesirable.

  In order to solve the above-mentioned problem that it is not possible to maximize the usable time that can be carried and used without suppressing the deterioration of the battery characteristics without leaving the portable device fully charged In Japanese Patent Laid-Open No. 2000-253596, “Secondary Battery Charging Device and Charging Method” of Patent Document 1, charging by the charger is completed when the battery is removed from the charger and starts to be used as a portable device. A technique for controlling the charging start time has been proposed.

  That is, in Patent Document 1, as a charger for charging a battery built in a portable device, remaining amount detecting means for detecting the remaining amount of the battery, and time setting means for setting the use start time input by the user And calculating the time required for the charging to be completed from the remaining amount of battery detected by the remaining amount detecting means so that the charging ends when the use start time set by the time setting means is reached. When the charging start time is reached and the charging start time is reached, the charging operation is started. As a result, when the use start time is reached, the battery reaches the fully charged state, and the time for leaving the portable device in which the battery is fully charged is reduced, thereby suppressing the deterioration of the battery characteristics. The usable time that can be carried and used can be maximized.

Terminal, PDA (Personal
The present invention can be applied to Digital Assistants) devices, notebook PCs (Personal Computers), portable audio devices, and the like.

(Features of the present invention)
Prior to the description of the embodiments of the present invention, an outline of the features of the present invention will be described first. The present invention controls the charging start time of the battery of the mobile device according to the usage status of the user's mobile device, thereby calculating the charging start time for each charging (in the case of Patent Document 1). The main feature is that the usable time that can be actually used with a portable device after charging the battery can be maximized without requiring the user to input information regarding the use start time). .

  In other words, the user usually uses the mobile device according to a predetermined schedule or the same as the usage status of the mobile device on a daily basis, so remove the mobile device from the charger and actually use it. The date and time (daily use start time) to start can be automatically estimated from the schedule information of the user of the mobile device or the past use history information of the mobile device. Therefore, the daily use start time estimated based on the schedule information or use history information is regarded as the time when the portable device is actually removed from the charger and actually used, and the use start time. Is characterized by controlling the daily charging start time so that becomes the charging completion time. Thus, even if the user does not have to perform troublesome operations such as inputting some information every time the battery is charged, the remaining battery level at the daily use start time is maximized, so that the mobile device is actually carried and used. The usable time that can be done can be maximized.

  Furthermore, by displaying the use start time estimated from the schedule information or use history information and presenting it to the user, the user can charge the portable device from the use start time different from the displayed use start time. If it is determined that the user wants to start using the device, the user can directly enter and specify the use start time while connected to the charger, and the use start time input by the user can be specified by the schedule information. Alternatively, it is characterized in that the charging start time is set in preference to the usage start time estimated from the usage history information.

(Configuration example of embodiment)
Next, a configuration example of an embodiment of the portable device according to the present invention will be described in detail with reference to FIG. FIG. 1 is a schematic diagram for explaining an example of the configuration of a portable device according to the present invention, and shows a state where the portable device is connected to a charger. As shown in FIG. 1, the mobile device 10 includes at least a battery 1, a storage unit 2, a charge controller 3, an operation unit 4, a display unit 5, and a clock 6.

  Here, the storage unit 2 stores at least the schedule information 21 in which the schedule of the user 30 of the mobile device 10 is registered and the usage history information 22 in which the history of the usage status of the mobile device 10 is registered.

  The charge controller 3 refers to the schedule information 21 and the use history information 22 stored in the storage unit 2, the date / time information of the clock 6, and the remaining amount information of the battery 1. The operation of charging the battery 1 with the charger 20 connected to the mobile device 10 with reference to the information input from 4 (for example, the use start time when the mobile device 10 is actually used after charging) Is controlling.

  That is, the charge controller 3 refers to the schedule information 21 and use history information 22 stored in the storage unit 2 and the remaining amount information of the battery 1, and the portable device in which the user 30 is connected to the charger 20. 10 is removed from the charger 20, the use start time at which the use is actually started is estimated, and the battery 1 is fully charged at the estimated use start time or at the use start time designated by the user 30. The charging start time is calculated so as to enter the state. Furthermore, the charge controller 3 refers to the clock 6 to acquire the current date and time, and starts the charging operation for the battery 1 from the charger 20 when the current date and time reaches the calculated charging start time.

  Note that the user 30 can perform an operation on the mobile device 10 using the operation unit 4 and the display unit 5, and can also notify the charge controller 3 of an instruction regarding a charging operation.

  The charger 20 has an AC power cord, converts AC power supplied from the AC power source into DC power, and is connected to the portable device under the control of the charge controller 3 of the portable device 10. 10 battery 1 charging operations are performed. The charger 20 is detachable from the portable device 10.

(Description of operation of embodiment)
Next, an example of the charging operation of the mobile device 10 shown in FIG. 1 will be described in detail. First, the case where the charge controller 3 controls the charging operation of the battery 1 of the portable device 10 will be described with reference to the schedule information 21 stored in the storage unit 2 with reference to the flowchart of FIG. FIG. 2 is a flowchart for explaining an example of a charging operation procedure of the battery 1 of the mobile device 10 according to the present invention, and shows an operation example of the charge controller 3 of the mobile device 10.

  Here, even if the portable device 10 is connected to the charger 20, the charge controller 3 does not immediately start the charging operation to the battery 1, but the user 30 removes the portable device 10 from the charger 20. Based on the time required for completion of charging calculated from the remaining battery level and the use start time, the charge start time is determined so that the battery will be fully charged at the start of use when it is actually carried and used. Take action to determine. In addition, in the flowchart of FIG. 2, the schedule information 21 memorize | stored in the memory | storage part 2 is referred for the use start time when the user 30 removes the portable apparatus 10 from the charger 20, and actually carries out and starts use. It is guessed by doing.

  In the flowchart of FIG. 2, first, the charge controller 3 confirms whether or not the charger 20 is connected to the portable device 10 (step S1). When the charger 20 is connected (YES in step S1), the charge controller 3 can immediately start the charging operation to the battery 1 without starting the charging operation even when the portable device 10 is connected to the charger 20. 2 is read (step S2). Next, based on the read schedule information 21, the user of the portable device 10 estimates the use start time when the user removes the portable device 10 from the charger 20 and actually carries it and starts using it (step S3). .

  Thereafter, the charge controller 3 acquires information on the remaining battery level from the battery 1 (step S4). Furthermore, based on the acquired battery remaining amount and information on the use start time estimated in step S3, a charge start time at which the battery 1 can be charged to a fully charged state at the time of use start time is calculated. (Step S5).

  Further, the charge controller 3 acquires the current time from the clock 6 (step S6), and monitors whether or not the acquired current time has reached the charge start time calculated in step S5 (step S7). When the charging start time is reached (YES in step S7), the charging operation from the charger 20 to the battery 1 is started (step S8).

  After starting the charging operation, the charging controller 3 monitors the charging state of the battery 1 and confirms whether or not the battery 1 has reached the fully charged state (step S9). When the battery 1 has not reached the fully charged state (NO in step S9), the charging operation from the charger 20 is continued, but when the battery 1 has reached the fully charged state (YES in step S9), the charger The charging operation from 20 is terminated (step S10).

  In the above charging operation, as shown in step S2 of FIG. 2, the user 30 uses the schedule information 21 of the user of the portable device 10 to connect the charger 20 to charge the portable device. After charging 10, the use start time at which use is started after being removed from the charger 20 is automatically estimated as the time according to the daily schedule. Thus, since the user 30 does not need to bother to input information such as the use start time by operating the operation unit 4 each time the battery is charged, the operability of the user 30 is eliminated. The power consumption of the battery 1 until reaching the use start time can be suppressed, and the usable time during which the portable device 10 can be carried and used can be maximized.

  In the flowchart of FIG. 2 described above, a case where the user 30 estimates the use start time when the user actually starts using the charged portable device 10 based on the schedule information 21 stored in the storage unit 2. Although described, the present invention is not limited to such a case. For example, in step S <b> 2 of FIG. 2, an operation of reading the usage history information 22 stored in the storage unit 2 is performed, and the usage history information 22 is used instead of the schedule information 21. You may make it guess the use start time which actually starts using the apparatus 10.

  Here, as the usage history information 22, historical information related to the usage start time of the mobile device 10 for each day of the week and each day is accumulated in the storage unit 2, and the past is determined according to the day of the week and date of the charging operation. The use start time may be estimated from the use history information. Furthermore, the use start time may be extracted by performing a weighting calculation with a greater weight for each use history information. In addition, the use start time estimated using the schedule information 21 and the use history information 22 is not limited to only one time, but a plurality of times are estimated, and from that time to the earliest arrival time It may be controlled to complete charging.

  Further, as another embodiment of the charging operation of the battery 1, it is estimated when the use start time is estimated based on the schedule information 21 and the use history information 22 stored in the storage unit 2 in step S3 of FIG. The use start time may be displayed on the display unit 5 and confirmed with the user 30.

  Here, in the case where the estimated use start time is displayed on the display unit 5 and the user 30 determines that the displayed use start time is acceptable, the processing after step S4 in the flowchart of FIG. And the charging operation is controlled so that the battery 1 is fully charged when the use start time is reached.

  On the other hand, when the user 30 decides to newly set a time different from the displayed use start time as the use start time, the user 30 operates the operation unit 4 to use the use start time that the user 30 wants to set. Is input to the charge controller 3. When the use start time is notified from the operation unit 4, the charge controller 3 is notified from the operation unit 4 rather than the use start time estimated based on the schedule information 21 and the use history information 22 in step S <b> 3. Further, the use start time designated by the user 30 is preferentially used, and the use start time designated by the user 30 is used to execute the processes after step S4 in the flowchart of FIG. When the use start time designated by the user 30 is reached, the charging operation is controlled so that the battery 1 is just fully charged.

  In addition, after displaying the use start time on the display unit 5 as an operation of displaying the use start time estimated based on the schedule information 21 and the use history information 22 on the display unit 5 and confirming to the user 30, If the use start time is not input from the operation unit 4 or the information indicating “OK” is input before the predetermined time elapses, the user 30 is inferred. On the other hand, it is considered that the use start time is acceptable. On the other hand, when time information is input from the operation unit 4 until the predetermined time elapses, information indicating "NG" is input. If there is a problem, the user 30 may consider that a time different from the estimated use start time is designated as the use start time.

  Further, as a further different embodiment of the charging operation of the battery 1, when the portable device 10 is connected to the charger 20, the charging controller 3 immediately starts the charging operation until the battery 1 is once fully charged. The battery is charged, and then, in a state where the charger 20 is connected, the operation of monitoring whether or not a situation in which the remaining amount of the battery 1 is lower than the fully charged state has occurred is continued. If a situation occurs in which the charging is reduced, as described above, the charging operation is performed again so that the battery is fully charged at the estimated use start time or the use start time designated by the user 30. You may control. Even if the mobile device 10 is used unexpectedly at a time other than the estimated use start time or the use start time specified by the user 30 by performing such a recharging operation, As in the case of the above-described embodiments, it is possible to maximize the usable time during which the portable device 10 can be detached from the charger 20 and used while maintaining the operability of the user 30.
