As shown in FIG. 3, the battery module 12 has a residual capacity extreme value at about 15 degrees Celsius, so if the battery module 12 can be controlled to discharge near this temperature, the battery module 12 can be released. More energy is produced. It should be noted that, under other discharge rate discharge conditions, the battery module 12 also has a similar trend, so the overall S' can be regarded as a relationship between the residual capacity of the battery module 12 and the discharge temperature, so as to qualitatively show the residual capacity. Corresponding to the trend of the discharge temperature; as described above, in the present embodiment, the relationship between the residual capacity and the discharge temperature has a discharge temperature range with a low residual capacity, and 201234738 can cover 15 degrees Celsius, so the battery module 12 This discharge temperature range discharges, releasing more energy. In actual time, the battery module I2 is disposed in the portable electronic device 2, and the energy released by the battery module 12 is used in addition to the trees in the portable electronic device 2, and indirectly generates heat energy. The temperature at which the group 12 is discharged, so to effectively suppress the residual capacity of the battery module η, also needs to consider the influence of the portable electronic device 2 on the discharge temperature of the battery module during operation. Please refer to FIG. 4 , which is a schematic diagram showing the relationship between the discharge temperature and the discharge rate of the battery module 12 in the portable electronic device 2 . The discharge temperature of the battery module 12 shown in Fig. 4 has been reflected by the discharge of the battery module 12 itself and the heat generated by the operation of other electronic components in the portable electronic device 2. The battery module 12 does not cover the entire discharge rate range in FIG. 4 in the general operation of the portable electronic device 2. The discharge rate of the battery pack 12 in the present embodiment is limited to the range of the small pure 8C. The discharge temperature is in the range of less than 6 degrees Celsius.

In the present embodiment, the processing module 16 of the power management system 1 is directly implemented by the processing chipset of the portable electronic device 2, but the invention is not limited thereto. Moreover, in practice, the current sensing module 14 can be integrated into the battery module 12, and the battery module 12 can provide discharge current information to the processing module 16 through a single connection interface. In addition, the battery module 12 may contain a discharge temperature range of _ _ each of the low residual capacity, which is different in practice, so the implementation of the 'battery module! 2 can store the corresponding low residual capacity discharge temperature range or - identification code, the processing module 16 reads the identification code and uses the identification code to judge: = corresponding low residual capacity discharge temperature range, and then according to the corresponding identification The relationship between the discharge temperature of the code and the discharge rate (see Figure 4) and the discharge temperature range of the low residual capacity 'determines the corresponding discharge compensation, as the basis for the consumption of the portable electronic I. In the case where there may be a plurality of pool modules 12 available for gamma, the above procedure for determining the discharge rate range is implemented by a comparison table, and the pair is stored in the memory 162 (see the 丨_, processing module). The comparison table is used to read the identification code surface nuances.

Of course, the method of down-clocking the processor can also be used. The foregoing manner does not affect the user. The direct use experience is the principle 'but the invention is not limited thereto. If the system is predictable, the aforementioned monitoring procedure can also be omitted, and the comparison is made to: record ^ off; #讯 as control portable electronic device 2 The basis for energy consumption is added. In practice, the processing module 16 controls the energy-consuming base of the expandable electronic device 2, the tank gamma ^ iQgie, the card _ HA (Kalman fiitering), the neural network (n_l network) and recursive, self-learning methods and the like are implemented, but the invention is not limited thereto. In addition, in the embodiment, the power management system i further includes a temperature sensing module 18 electrically connected to the processing module 16 for sensing the temperature of the battery module 12. Therefore, the power management secret 1 can determine whether the temperature of the low residual Lugu amount is within the discharge temperature range of the group 12, and the energy consumption or feedback of the portable electronic device 2 can be adjusted according to the situation to correct the discharge rate. range. The foregoing has explained the functions of the components of the power management system according to the present invention, and the power management method according to the present invention will be further described below. Please refer to FIG. 5, which is a flow chart of a power management method in accordance with a preferred embodiment. For convenience of explanation, the power supply B method directly takes the power management system 1 as an example, so the related description of the power management system 1 is also applicable here. Please refer to the foregoing and its drawings, and no longer repeat. 11 201234738 This implementation of the power management method, _, or its combination is not limited to this. As shown in FIG. 5, the method of using the processing module 16 first reads and stores one of the battery modules 12, such as step S1, and then uses the processing module. Group 16 is based on the read_single S110.疋 疋 疋 , , , , , , , , , , , , , , , , , , , , , , , , 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋 疋12 According to the chargeable discharge rate of the portable money, the re-distribution group 16 is based on the discharge rate corresponding to the discharge rate and the discharge temperature of the low residual capacity is fine, and the mosquitoes should be placed in a group. In the present embodiment, the discharge temperature range of the low residual capacity is as in the temperature range 122 shown in Fig. 3, about 1 G to 35 degrees Celsius; and the discharge rate side is the discharge rate range 124 of the lion in Fig. 4. It is to be noted that when the portable electronic device 2 uses only a single type of battery module 12, the discharge rate range can be stored in the memory 162 in advance, and the processing module π can be directly read. The differences in the rate of electricity generation must be omitted. In addition, when the battery module 12 includes multiple types of situations, the comparison table can be used to directly record the discharge threshold of the f-pool module U corresponding to each surface, and the identification group can directly use the comparison table to read the identification. The code finds the discharge rate range. Moreover, if the difference between the discharge rates of the discharge temperatures of the different batteries 12 is not large, in practice, the discharge temperature range of the low residual capacity can be stored in the battery module 12, and the processing module 16 can utilize the self-battery. The discharge temperature range of the low residual capacity read by the module 12 and the discharge rate corresponding to the discharge rate determine the discharge rate range, whereby the setting of the a 12 201234738 comparison table can be omitted. Then, the power management method uses the current sensing module 14 to sense the discharge current of the battery module 12, as shown in step S120; then, it is determined whether the sensed discharge current falls within the discharge rate range, as in step S13. See also. If the result of the determination in the step S130 is affirmative, that is, the battery module 12 is discharged within the discharge rate range, the flow of the power supply method returns to the step S120. If the result of the determination in step S130 is negative, the power management method uses the processing module 丨6 to control the energy consumption of the portable electronic device 2 according to the sensed discharge current, as shown in step §14〇, thereby enabling the battery The discharge current of the module 12 can be corrected toward the discharge rate range; the flow of the power supply method then returns to step S120. In principle, the steps S1, s, s3, and s4 are formed into a loop process, so that the discharge current of the battery module 12 is continuously pressed, so that the battery module 12 can be discharged within the discharge rate range, thereby implementing the suppression battery module 12. The residual capacity improves the efficiency of the battery module 12 to release energy storage. In the implementation of the step S14, the means for controlling the energy consumption of the portable electronic device 2 has an evening mode, such as limiting the number of applications of the portable f-sub-device, and selecting __ portable The application program, program and software components of the electronic towel, and the amount of resources for limiting the running of the portable electronic device.

And soft navigation, and 13 201234738 information on power consumption, central processing unit rate, pre-production background execution, and system temperature of the portable electronic device; thereby, the power management method can use the information obtained by the monitoring Energy consumption adjustment of the playable electronic device 2. For other explanations about energy consumption control, please refer to the previous description and we will not repeat them. In addition, since the discharge rate range is based on the discharge temperature range of the low residual capacity, the battery module 12 is used when the original shame t battery is difficult to discharge within the discharge rate range. The temperature is also in the discharge temperature range of the low residual capacity. In the case of the threat, the electricity-saving method can ride the temperature of the monitoring group η❿ to confirm the temperature difference of the battery pool 12 and the discharge temperature of the low residual wire amount, and adjust the portable electronic device 2 as the case may be. Energy consumption reference or feedback correction related control parameters. Please refer to FIG. 6, which is a flowchart of a power management method according to an embodiment. The recording of FIG. 6 is substantially the same as the flowchart of FIG. 5, except that the power supply method of the embodiment further includes: when the determination result of the step sl3 is affirmative, the temperature sensing is not required to be used first. The module 18 senses the temperature of the battery module 12 as shown in step si5 ;; and then determines the temperature gambling _ low discharge capacity discharge temperature range of the battery module 12, as shown in step S16G. If the result of the determination in the step S16Q is affirmative, that is, the battery gas group 12 is discharged within the discharge rate range and the discharge temperature range of the low residual capacity, the flow of the power management method returns to the step sl2. If the result of the determination in the step S160 is negative, the power management method continues to step 314. 14 201234738 _ Explain that, since step S120 to step sl4 〇 form a loop process, in practice, the step of measuring the energy consumption of the light-collar electronic device 2 that needs the second-time coffee is self-borrowing The battery module 12 is discharged within the discharge temperature range of the discharge rate range and the low residual capacity by continuously and periodically adjusting the operation; however, the invention is not limited thereto. In addition, the power management method can be implemented - the number of steps from step S16G to the step is measured to start the operation of correcting the range of the electric power rate. This can solve the components that may be generated after the long-term use of the portable electronic device 2. The aging Lu phenomenon or other factors cause the setting of the original discharge rate range to deviate from the problem of achieving the purpose of suppressing the residual capacity of the battery module 12. The foregoing embodiments mainly sense the discharge current of the battery amount 12 as a basis for controlling the energy consumption of the portable electronic device, but the invention is not limited thereto. See the first! Figure 7 and '7' are flowcharts of a power management method in accordance with another preferred embodiment. For the sake of convenience, the foregoing electrical age system is still taken as an example, but the invention is not limited thereto. The flowchart of FIG. 7 is substantially the same as the flowchart of FIG. 5, except that the power management method of the present embodiment senses the temperature of the battery module 12 as a basis for controlling the reduction of the portable device 2 . Therefore, if the power management method is to read the battery module, the identification code of the group 12 (as shown in step 1), then determine the discharge temperature range of a low residual capacity, such as the step 1 Shown. After that, the power management method first senses the temperature of the battery module 12, as shown in step 20; then, it is determined whether the sensed temperature falls within the discharge temperature range of the low residual capacity, as shown in step S230. . If the result of the determination in step S230 is affirmative, 15 201234738, the flow of the power management method returns to step (10); if the result of the determination in step (4) is negative, the power management method utilizes the processing module 16 according to the sensed temperature.
