The charging control unit 22 of the power supply circuit 120 determines that the susceptor 22 is in contact with the susceptor 22 and is connected to the pedestal of the electronic device 1 by detecting the coupling of the susceptor 22 and/or detecting the presence of the charging voltage. Terminal portion 154. In accordance with this determination, the charging control unit 122 causes the charging/discharging unit 124 to charge the secondary battery unit 140 to the second maximum ratio Pmax2 (e.g., 8 G%) of the maximum chargeable amount. Thereafter, the 'charge (four) portion 122 is stopped regardless of the coupling of the electronic device 1 and the susceptor 220, and when the amount of power remaining 16 201019567 of the secondary battery device 14 falls to the second minimum ratio Pmin2 of the maximum chargeable amount, the stop Charge and do not start charging. Thereby, the secondary battery unit 140 can be suppressed from being charged to the full state, and the life of the secondary battery unit 140 can be further extended. Further, when the remaining amount of electric power of the secondary battery device 140 is not full, and is lower than the third minimum ratio Pmin3 of the maximum chargeable amount of 5 (for example, 85%, 80%, or 75%), it is connected to a USB terminal of a personal computer PC or the like. The USB connector 236 is directly connected to the USB connector 156 of the electronic device 100. In this way, the detecting unit 电源3〇 of the power supply circuit 120 detects the higher voltage level 5 (5·0ν) of the power supply terminal #1 of the USB connector 236 via the power feeding terminal 182, and displays the display 10 to detect the USB. A signal (Η) coupled by the connector 236 is supplied to the charging control unit 122. The detecting unit 130 or the charging and discharging unit 124 can further detect a supply voltage (for example, 5 〇v) from the power feeding input terminal PS#3 of the power feeding terminal 182, and supply a signal (H/L) indicating the presence of the charging voltage to the charging. Control unit 122. The charging control unit 122 of the power supply circuit 120 determines that the USB connector 236 is connected to the USB connector 156 of the electronic device 100 by detecting the coupling of the USB connector 15 236 and/or detecting the presence of the charging voltage. According to this judgment, the charging control unit 122 causes the charging/discharging unit 124 to charge the secondary battery unit 140 to the third maximum ratio Pmax3 of the maximum chargeable amount. Thereafter, the charging control unit 122 stops charging when the power remaining amount of the secondary battery device 140 falls to the third minimum ratio pmin3 of the maximum chargeable amount irrespective of the coupling of the electronic device 1A and the USB connection device 236. And do not start charging. Thereby, it is possible to suppress the secondary battery unit 14 from being charged to the full state, and the life of the secondary battery unit 14 is further prolonged. Fig. 5 is a view showing another variation of the embodiment of Fig. 3, showing a possibility that the power supply circuit 120 in the electronic device 100 of the other aspect of the present invention is different from the AC to DC converter 202 for charging. Two types of coupling patterns. The cable connector (DC_CBL) 232 of the AC-DC converter 202 is the same as the aspect of FIG. 3, and includes the ground terminal 5 #1 (GND) and the power supply terminal #5 (5_4V) in the terminals #1 to #10. And the ground terminal #10 0 at this time, the spare terminal #6 (RSV) of the inverter 202 is not used. At this time, the ARIB connector 152 of the electronic device 100 includes the ground terminal 161, the power supply terminal 165, and the ground terminal 170 in the same manner as in the third and fourth aspects. The power supply terminal 165 is connected to the power input terminal 10 terminal PS' of the power supply circuit 120 and is not connected to the detecting portion 130. The cable connector detection terminal 166 of Figure 3 is not used. The susceptor 220 is similar to the embodiment of Fig. 4 and includes terminals - 261, 265, 270, contact terminals 222, 223 and permanent magnet 225. The base terminal portion 154 of the electronic device 100 is the same as that of Fig. 4, and includes a contact terminal 175, 180 and a magnetic sensor 155. The detection terminal of the magnetic sensor 155 is connected to the detecting portion 130 of the power supply circuit 120. The contact terminal 175 for power supply is connected to the grounding ® input terminal PS of the charging and discharging portion 124 of the power supply circuit 120. When the remaining amount of power of the secondary battery device 140 is not full and is lower than the first minimum ratio Pmin1 (for example, 90%, 85%, 80%) of the maximum chargeable amount of 20, the cable connector 232 of the AC-DC converter 202 It is directly connected to the ARIB connector 152 of the electronic machine 100. Thus, the detecting unit 130 of the power supply circuit 12 does not detect the detection signal (H) of the permanent magnet 255 by the magnetic sensor 155, and supplies the detection signal (L) in which the coupling of the display base 220 does not exist to 18 201019567 Charging control unit 12 2 . The detecting unit 130 or the charging/discharging unit 12 4 can further detect a supply voltage (e.g., 5.4 V) from the power supply terminal PS of the power supply terminal 165, and supply a signal (Η) indicating the presence of the charging voltage to the charging control unit 122. The charging control unit 122 of the power supply circuit 120 determines that the AC-DC converter 202 is directly connected to the ARIB connector 152 of the electronic device 100 without detecting the coupling of the susceptor 220 and detecting the presence of the charging voltage. In accordance with this determination, the charging control unit 122 causes the charging/discharging unit 124 to charge the secondary battery unit 140 to the first maximum ratio Pmax1 of the maximum chargeable amount. Thereafter, the charge control unit 122 stops when the power remaining amount of the secondary battery device 140 falls to the first minimum ratio Pmin1 of the maximum chargeable amount regardless of the coupling of the electronic device 1 and the electric gauge connection 10; Charge and do not start charging. Thereby, it is possible to suppress the secondary battery device 140 from being frequently charged to the full state, and the life of the secondary battery device 140 is further prolonged. Alternatively, the first minimum ratio Pmin1 may not be set, and as in general, when the remaining amount of electric power of the secondary battery unit 140 is slightly lowered from the full state, the secondary battery unit 140 is charged. On the other hand, when the remaining amount of electric power of the secondary battery device 140 is not full and is lower than the second minimum ratio Pmin2 (for example, 80%) of the maximum chargeable amount, the AC-DC converter 202 is connected to the susceptor 220 and the electrons. The machine 1 is placed on the 20 base 222, whereby the contact terminals 222, 223 of the base 220 are in contact with and connected to the contact terminals 175, 180 of the base terminal portion 154 of the electronic device 100. Thus, the power supply circuit 120 operates in the same manner as in the fourth embodiment. Thereby, the charging of the secondary battery device 140 to the full state can be suppressed, and the life of the secondary battery device 140 can be further extended. 19 201019567 Fig. 6 is a modification of the third embodiment or the fifth embodiment, and further shows that the power supply circuit 120' in the electronic device 1' of the other embodiment of the present invention and the AC current conversion for charging Two different types of coupling modes between the two 2nd and 2nd.

Start charging. Thereby, it is possible to suppress the secondary battery device 140 from being frequently charged to the full state, and the life of the secondary battery device 140 is further prolonged. Alternatively, the first minimum ratio Pmin1 may not be set, and as in general, the secondary battery device 140 is charged when the power remaining amount of the secondary battery device 140 is only slightly lowered from the full state. On the other hand, when the remaining power of the secondary battery device 14 is not full and is lower than the second minimum ratio pmin2 (for example, 80%) of the maximum chargeable amount, the AC-15 DC converter 202 is connected to the susceptor 220, Further, the electronic device 1 is placed on the base holder 222, whereby the contact terminals 222, 223 of the base 220 are in contact with and connected to the contact terminals 175, 180 of the base terminal portion 154 of the electronic device 100. Thus, the detecting portion 130' of the power supply circuit 120 detects a detection signal of a higher voltage level H (5 4 V) from the contact terminal 156 where the display base 220 is coupled, and detects the coupling of the display base 220. The signal (H) is supplied to the charging control unit 122.

The charging control unit 122 of the power supply circuit 120 determines that the susceptor 220 is in contact with and is connected to the susceptor terminal portion 154 of the electronic device 100 by detecting the presence of the susceptor 22 2010 21 201019567 and/or detecting the presence of the charging voltage. Based on this determination, the charging control unit 122 causes the charging/discharging unit 124 to charge the secondary battery unit 140 to the second maximum ratio 5 Pmax2 (e.g., 80%) of the maximum chargeable amount. Thereafter, the charging control unit 122 stops charging and does not start charging when the remaining amount of power of the secondary battery device 140 falls to the second minimum ratio Pmin2 of the maximum chargeable amount regardless of the coupling between the electronic device 100 and the susceptor 220. .

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 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.

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.

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.

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. Charge it.
Step 460 is the same as step 420. 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.

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).

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.
