Figs. 8A and 8B are flowcharts for showing the charging control performed by the charging control unit 122 of the power supply circuit 12. Referring to Fig. 8A, in step 402, the charging control unit 122 of the power supply circuit 120 determines whether or not the charging voltage is detected by the charging/discharging unit 丨24 (voltage current detecting unit 丨25). When it is judged that the charging voltage is not detected, step 402 is repeatedly performed until the charging voltage is detected. When it is judged that the charging voltage is detected, the program proceeds to step 404. In step 404, the charging control unit 122 determines which of the USB connectors 236 is determined to be coupled to the coupling element of the electronic device 100, and is in the configuration of the cable connector 232, the susceptor 22, and the fourth figure. In step 404, when it is determined that the cable connector 232 is coupled to the electronic device 1, the program proceeds to step 412. In step 404, when it is determined that the cradle 220 is coupled to the electronic device, the program proceeds to step 412. In step 404, when it is determined that the USB connector 236 is coupled to the electronic device 100, the program proceeds to step 412. In step 412, the 'charging control unit 122' will correspond to the charging of the cable connector 232 by the memory 1〇4 or the thresholds Pmax 1 to Pmax3 and Pmin 1 to Pmin3 stored in the threshold 5 recall area 123. The remaining power amount (maximum ratio) pmaxl (for example, 1〇〇%) at the end of charging, and 23 201019567 power remaining amount (minimum ratio) Pminl (for example, 90%) at the start of charging are set as applicable threshold values. In step 414, the charging control unit 122 causes the power remaining amount detecting unit 128 to detect the value P(Ah) of the current remaining amount of the secondary battery device 130 or the ratio P (%). In step 416, the charging control unit 122 determines whether or not the current remaining amount of power P is smaller than the remaining amount of power (minimum ratio) pmin1 at the start of charging. Step 416 is repeatedly performed until it is judged that the current remaining amount p of power is equal to or less than the remaining amount of power Pminl at the start of charging. In step 416, when it is determined that the current remaining amount of power is equal to or less than the remaining amount (minimum ratio) Pmin1 at the start of charging, in step 418, the charging control unit 122 causes the charging and discharging unit 124 to start the secondary battery unit 130. Charging. In step 420, the charging control unit 122 causes the power remaining amount detecting unit 128 to detect the value P(Ah) or the ratio P (%) of the current remaining amount of the secondary battery device 130. In step 422, the charging control unit 122 determines whether or not the current remaining amount of power 15 P is the power remaining amount (maximum ratio) Pmax 1 or more at the end of charging. When it is determined that the current remaining amount P of electric power is equal to or greater than the remaining amount of electric power at the end of charging (maximum ratio) Pmax1, the routine shifts out the routine of Fig. 8A, and the charging is completed. When it is determined in step 422 that the current remaining amount of power p is not equal to or greater than the power remaining amount (maximum ratio) Pmax1 at the end of charging, the charging control unit 122 causes the charging and discharging unit 124 to continue the secondary battery device 130 in step 424. Charging. In step 426, the charging control unit 122 determines whether or not the charging voltage is detected by the charging/discharging unit 124 (voltage current detecting unit 125). When it is judged that the charging voltage is not detected, the program shifts out the routine of Fig. 8A, and the charging is completed. When the charging voltage is detected in step 426, the program returns to step 420, 201019567. In step 422 or step 426, steps 420-426 are repeated to the program to shift out the routine of Fig. 8A. In step 432, the 'charge control unit 122' is the remaining amount of power (maximum ratio) Pmax2 (for example, 80%) at the end of the charge 5 corresponding to the charging by the susceptor 220 among the threshold values Pmax1 to Pmax3 and Pmin1 to Pmin3. And the remaining amount of power (minimum ratio) Pmin2 (for example, 70%) at the start of charging is set as an applicable threshold. Step 434 is the same as step 414. In step 436, the charging control unit 122 determines whether or not the current remaining amount of power P is equal to or less than the remaining amount of power 10 (minimum ratio) Pmin2 at the start of charging. Step 436 is repeatedly performed until it is judged that the current power remaining P is equal to or less than the remaining power amount Pmin2 at the start of charging. When it is determined in step 436 that the current remaining amount of power p is equal to or less than the remaining amount of power (minimum ratio) Pmin2 at the start of charging, in step 438, the charging control unit 122 causes the charging and discharging unit 124 to align the secondary battery unit 13 with the charging/discharging unit 124. Start charging in 15 lines. Step 440 is the same as step 420. In step 442, the charging control unit 122 determines whether or not the current remaining amount of power p is equal to or greater than the remaining amount of power (maximum ratio) Pmax2 at the end of charging. When it is judged that the current remaining amount p of electric power is equal to or greater than the remaining amount of electric power (maximum ratio) Pmax2 at the end of charging, the routine shifts out the routine of Fig. 8A and the charging is completed. In step 442, when the current remaining amount p is not equal to or greater than the remaining power amount (maximum ratio) pmax2 at the end of charging, the charging control unit 122 causes the charging/discharging unit 124 to continue the secondary battery unit 13 in step 444. Charging. Step 446 is the same as step 426. 25 201019567 When the charging voltage is detected in step 446, the program returns to step 44, and in step 442 or step 446, steps 440 to 446 are repeatedly performed until the program shifts out the routine of Fig. 8A. Referring to Fig. 8B, in step 452, the charge control unit 122 sets the remaining amount of power at the end of charging corresponding to the charging by the USB connector 236 among the values max5 to Pmax1 to Pmax3 and Pmin1 to Pmin3 ( The maximum ratio) Pmax3 (for example, 90%), and the remaining power amount (minimum ratio) Pmin3 (for example, 80%) at the start of charging are set as applicable threshold values. Step 454 is the same as step 414. In step 456, the charging control unit 122 10 determines whether or not the current remaining amount of power P is equal to or less than the remaining amount of power (minimum ratio) Pmin3 at the start of charging. Step 456 is repeatedly performed until it is judged that the current remaining amount P is equal to or less than the remaining amount Pmin3 at the start of charging. In step 456, when it is determined that the current remaining amount of power p is equal to or less than the remaining amount of power (minimum ratio) Pmin3 at the start of charging, in step 458, the charging 15 control unit 122 causes the charging and discharging unit 124 to start with the secondary battery device 130.

In step 462, the charging control unit 122 determines whether or not the current remaining amount of power P is equal to or greater than the remaining amount of power (maximum ratio) Pmax3 at the end of charging. When it is judged that the current remaining amount P of power is equal to or greater than the remaining amount of power (maximum ratio) Pmax3 at the time of charging the bundle 20, the program shifts out the routine of Fig. 8B, and the charging is completed. In step 462, when it is determined that the current remaining amount of power p is not equal to or greater than the power remaining amount (maximum ratio) Pmax3 at the end of charging, the charging control unit 122 causes the charging/discharging unit 124 to continue the secondary battery device 130 in step 464.

In step 462 or step 466, steps 460 to 466 are repeated to the routine of flowchart 8A. 5 Fig. 9A is a flow chart showing the display operation in the display device 108 at the start of charging performed by the CPU 102 of the electronic device 100 according to the power management function in the application 110. This display operation is a display operation initiated by the execution of steps 418, 438, and 458 (charge start) in Figs. 8A and 8B. 10 Fig. 9B shows an example of a display screen of the display device 108 in the display operation of Fig. 9A. Referring to Fig. 9A, in step 502, the CPU 102 reads the required maximum charge amount or ratio 15 Pmax which is set among the maximum charge amounts pmax1 to Pmax3 stored in the threshold setting memory area of the charge control unit 122. In step 504, as shown in the display screen example of FIG. 9B, the CPU 102 displays the maximum amount of charge or the ratio Pmax (for example, 80%) required for reading in a predetermined position on the display screen of the display device 108, and displays the charging. The pattern of the state (such as the socket, the map of the transplant). In this way, the town informs the user of the current level of charge required. In step 506, as shown in FIG. 9B, the CPU 102 is attached to a predetermined position in the display screen of the display device 108, and the maximum charge amount or ratio Pmax required for notification is displayed only for a predetermined time (for example, 5 seconds).

This allows the user to strongly identify the current level of charge required. 27 201019567 5 Figure 10A shows a flow chart showing the display operation in the display 108 at the end of charging of the CPU1G2 (4) line of the electronic camera according to the power management function in the application 110. This display operation is performed by the end of the routine in Fig. 8B (the end of charging). Fig. 1B shows an example of the display device 1〇8 in the display operation of Fig. 10A. When the CPU 1〇2 is in the step S512, the CPU 1〇2 is charged by the electric power remaining amount detecting unit 128 by the charging control unit 122 as the amount of charge or the ratio P (for example, Pmax). It is detected and read in the amount or ratio of the charge. In step 514, as an example of the display screen of Fig. 1B, the CPU 102 is displayed at a predetermined position in the display screen of the display device 108, and the charge amount P (e.g., 80%) is displayed. In step 516, the CPU 102 detects the electric power remaining amount as the charging amount or the ratio P by the electric power remaining amount detecting unit 128 via the charging control unit 122 while the electronic device 1 is operating, and reads the charging amount or proportion. In step 518, the CPU 1 判断 2 determines whether the detected current remaining amount of power is less than the amount of charge P at the end of charging - a predetermined amount Pr (for example, 1%) (p - P (%)), that is, by the end of charging The amount of charge P at the time is judged whether it is lower than the predetermined amount Pr or more. When it is judged that the amount of charge p_ is less than the predetermined amount pr(p - Pr) at the end of charging, the routine proceeds to step 520. In step 518, steps 516-518 are repeated to determine that the amount of charge P is less than the predetermined amount pr(p - pr) at the end of charging. In step 520, the CPU 102 stops the display of the amount of charge p at the end of charging. In this way, excessive information display can be suppressed to reduce power consumption.
