Description of the Invention: [Technical Field] The present invention relates to a hybrid power supply method for an electric device, and more particularly to a combination of a secondary battery and a fuel cell as a hybrid power source for supplying power to a power device . [Prior Art] • A power-on device such as a notebook computer uses a secondary battery as a power source in a place where there is no mains. The use of secondary batteries is convenient, but there are still disadvantages that require longer time charging. If the state of charge of the secondary battery is close to zero, if there is no other source of power at this time, the power device will be unable to be used due to lack of power supply. Therefore, the hybrid power including the secondary battery and other power sources is included. Born to respond. In the conventional hybrid power, a hybrid power combining a secondary battery and a fuel cell has begun to be applied to a consumer. Since the fuel cell has a charge-free characteristic, the fuel cell can generate electric power as long as the fuel is injected. Therefore, in the conventional hybrid power combining the secondary battery and the fuel cell, the fuel cell uses the main power as the main power. The secondary battery is used as a secondary power, that is, when only the Wei battery can generate enough power, it only depends on the battery's power, and when the fuel battery cannot generate electricity, or the power generated. When the power supply device is not enough, the power to the secondary battery is used. The third is not a combination of the secondary battery and the battery, and the power supply state diagram of the fuel cell and the secondary battery. The power output curve 1 is the power supply state of the relay battery. The electric residual state curve 2 is the power supply state of the 5 201021359 representing the secondary battery. Before the time T1, the hybrid electric power only supplies the electric power to the electric power device, and the secondary battery does not supply any electric power, so the secondary battery electric power state curve 2 is maintained. Between the time % and the time T2, the battery cannot supply power, but the power supply to the consumer is replaced by the secondary f-cell. The Staeof Charge of the secondary battery gradually decreases. Between the times L and _T3, the fuel cell has recovered to generate electric power, and therefore, the supply of electric power to the electric device is resumed, and at the same time, the secondary battery is charged. After the time point of time ❹3, the power of the secondary battery has been charged to the original state of charge. 'The hybrid power is only supplied by the fuel cell electric device again, and the secondary battery does not supply any electric power, so the state of charge state 2 remains the same. . The inventors of the present invention have improved the hybrid power supply in view of the above-mentioned problems, and have improved the hybrid power supply method of the paste electric device. SUMMARY OF THE INVENTION An object of the present invention is to provide a hybrid power supply method for an electric device, which can achieve a power supply function of hybrid electric power, and can also obtain an effect of a low attenuation rate of the secondary battery. Another object of the present invention is to provide a hybrid power supply method for an electric device, which can achieve a hybrid electric power supply function of a secondary battery and a fuel cell, can obtain a low attenuation rate of the secondary battery, and prolong the service life of the fuel cell. . Further, another object of the present invention is to provide a secondary battery capable of achieving hybrid power supply in combination with external power, and it is possible to obtain a low attenuation rate of the secondary battery. In order to achieve the above object, the present invention provides a hybrid power supply method for an electric device as claimed in the scope of the patent application, and a secondary battery as claimed in claims 7 and 5 of the patent application. In order to enable the reviewing committee to have a deeper understanding and understanding of the structure, features and functions of the present invention, the preferred embodiments are described in detail with reference to the drawings as follows: [Embodiment] The present invention is applied to an electrical device. The characteristic of the hybrid power supply method is that the main power supplier of the electric device is mainly a secondary battery, and only when the state of the secondary battery drops to the X!% state of charge, the fuel cell device starts to start and then the φ power supply . The operating fuel cell device charges the secondary battery and • can replace the secondary battery to supply power to the consumer, and always supply power to the secondary power. The battery state returns to the Y% state. When the state of the secondary battery returns to the Y% state of charge, the fuel cell device is turned off and the secondary battery is restored to supply power to the consumer. In the case where the fuel cell device supplies power to the electric device, if the total power generation amount of the fuel cell device cannot cope with the current power consumption of the electric device, the 'secondary battery will supply power to the electric device at this time' This provides hybrid power to the fuel cell device to power the electrical equipment 201021359. - The second A, B _ shows the silk diagram of the power supply method of the present invention, the third diagram shows that the specific method of the power supply method of the present invention is not applied, and the fourth figure shows the control unit of the secondary battery of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A block diagram, and a fifth diagram, show a state of charge state-time characteristic of a secondary battery in which the hybrid power supply method of the present invention is performed. The hybrid power supply method 1() is used as the hybrid electric power of the paste secondary battery 20 and the fuel cell device 30, and the electric power source of the electric device 4〇 is executed by the hybrid power supply method 1 The secondary battery 20 (four) amount state and the fuel cell 20 determine the power supply state of the electric device 4A, and the hybrid power supply method 10 includes steps 100 to l9c, which are respectively described below. Step 100 is to provide secondary battery 2 〇 and fuel cell device 3 作 as hybrid electric power. Please refer to the third and fourth figures. The secondary battery 2 includes a control unit 21, a charging module 22, and a secondary battery unit (Battery Cel 1) 24. The electric power of the φ secondary battery core (group) 24 can be used as a power source for the electric device 40. The charging module 22 is for receiving power from the fuel cell device 3 and converting it into a charging current and a charging voltage that meet the charging electrical requirements of the secondary battery unit 24, and transferring the power of the fuel cell device 30. The power supply device 40 〇 control unit 21 is a hybrid power supply method for performing the present invention. The electronic switches 23a, 23b are controlled by the battery capacity detecting module 21B. The fuel cell device 30 includes a controller 31 (Controller), a booster (Booster) 32, 201021359, and a fuel cell 33. The power of the fuel cell 33 can be used as a source of electric power for the electric device. The booster 32 is used to convert the power of the fuel cell 33 into a voltage that meets the electrical requirements of the charging module 22. The controller 3 is used to control the operation of the fuel cell 33 and the booster 32, At the same time, the controller 31 transmits signals to the control unit 21 of the secondary battery 20 in both directions or in one direction by the communication means 27. The specific embodiment of the control unit 21 can be composed of the microcontroller 21A and the battery capacity detecting module 21B. Furthermore, the microcontroller 21A and the battery capacity detecting module 21B can be implemented as a single integrated circuit (ic). The battery capacity detecting module 21B functions to detect the SOC-State of Charge of the secondary battery cell 24, protect the secondary battery (to prevent overvoltage, overcurrent, etc.), and to charge the battery. The status signal is transmitted to the microcontroller 21A. Another function of the charging module 22 is to detect the current total power generation of the fuel cell stack at any time, and the charging module 22 transmits an electrical signal 22a (eg, a voltage signal) representing the current total power generation of the fuel cell 33. To the control unit 21. The control unit 21 can determine whether the current total power generation amount of the fuel cell 33 is sufficient according to the electrical signal 22a and the current secondary battery cell (group) 24 power consumption signal from the battery capacity detection module 21B. The current power consumption of the electric device 40 is dealt with. Step 102 is to supply power to the electric device 40 by using the secondary battery 20 (step 102a), and in the power supply state of the secondary battery 20, the control unit 21 detects the state of charge of the secondary battery unit (group) 24 with 201021359. When the control unit 21 detects that the state of charge of the secondary battery unit (group) 24 is less than 沁% (step i〇2b), the control unit 21 causes the fuel cell device 3 to start (step 1〇2c), and The secondary battery 2 〇 still supplies power to the electric device 40 before the fuel cell device 30 completes the startup (step 102d). On the other hand, if the state of charge of the secondary battery unit (group) 24 is greater than or equal to 沁%, the process returns to step 1〇2a. In step 102, please refer to the third figure, the period during which the secondary battery 20 supplies power to the power source device 40, that is, the state of charge of the secondary battery cell (group) 24 is greater than or equal to the secret lying, or During the two periods before the completion of the activation of the battery device 3, the control unit 21 keeps the electronic switches 23a, 23b turned on, so that the current of the secondary battery unit (group) 24 will enter the power supply. Device 40. When the control unit 21 detects that the state of charge of the secondary battery cell (group) 24 is less than the secret time, the control unit 21 transmits the activation signal to the control device 31 via the communication means 27, and processes the thief signal, and then receives the spurt signal. The controller 31 activates the fuel cell 33. The secondary battery 20 can supply the power required for the wire to the battery pack 30 during the period before the fuel cell device 30 completes the startup. Step 104: When the fuel cell device is fully activated, and the normal operation of the fuel cell device 3, the secondary battery cell 24 is charged and the power device 40 is powered. The controller 31 operates the booster 32, and the booster 32 outputs a charging voltage to the charging module 22 such that the fuel cell device 3() can charge the secondary 201021359 battery 20. At the same time, the operating charging module 22 can transfer the current output by the booster 32 to the powered device 4, so that the fuel cell device 30 can supply power to the powered device 40. In step 104, please refer to the third figure. After the fuel cell device is activated and operating normally, the charging module 22 transmits an electrical signal 22a (eg, a voltage signal) representing the current total power generation of the fuel cell 33. To the control unit 21. The control unit 21 can know from the electrical signal 22a that the fuel cell 30 has started the power generation operation. Alternatively, after the fuel cell device 30 is fully activated and operating normally, the controller 31 transmits the completion activation signal to the control unit 21 via the communication means 27, so that the control unit 21 can know that the fuel cell 30 has started the power generation operation. A specific example of the electrical signal 22a described above may include at least a power generation signal of the fuel cell 33 and a plug-in signal of the fuel cell 33. After the fuel cell device 30 has started the power generation operation, the control unit 21 causes the charger module 22 to operate, and the control unit 21 maintains the electronic switches 23a, 23b conductive. From this point on, the secondary battery cell 24 is in a charged state. The charging current from the charging module 22 passes through the electronic switches 23a, 23b and enters the secondary battery cell (group) 24. Further, the charging module 22 transfers the current output from the booster 32 to the consumer 4, thus achieving power supply to the consumer 40 by the fuel cell device 3. The point in time at which the fuel cell slurry 30 is completed and operating normally is 11 201021359 which occurs at a certain point in time when the state of charge of the secondary battery cell (group) 24 is between χ2%. Step 106 is when the fuel cell device 30 cannot complete the startup, and the control unit 21 detects that the state of charge of the secondary battery 20 is less than X2%, so that the secondary battery 20 stops power supply to the power device 4〇, and controls The unit 21 further notifies the electric device 40 before the secondary battery 20 stops supplying power to the electric device 40, so that the electric device 40 enters the power saving mode or is turned off, and at the same time, the control unit 21 causes the fuel cell device 30 to be turned off. In step 106, please refer to the third figure, the possible situation that the fuel cell device 3 can not complete the startup, for example, the fuel cell device 3 is faulty; meanwhile, because the fuel cell device 30 is in the period before the startup is completed, Since the secondary battery 20 supplies power to the electric device 40, the state of charge of the secondary battery 2 持续 continues to decrease. When the control unit 21 detects that the state of charge of the secondary battery 2 is less than χ2%, the control unit 21 disables the electronic switches a 23a, 23b, thus electrically disconnecting the secondary battery 20 from the powered device 40. . Furthermore, before the control unit 21 causes the secondary battery 2 to stop supplying power to the consumer, the control unit 21 transmits a signal to the consumer via the communication means 28, notifying the consumer 40 to immediately enter the power saving mode or shut down. At the same time, the control unit 21 will shut down the fuel cell unit 30. In step 108, when the fuel cell device 3 is in the middle of the secondary battery 2, the control unit 21 turns off the fuel cell device 30 when the control unit 21 is at least γ 201021359%. At the same time, the control unit 21 causes the secondary battery 2 to directly supply power to the powered device 4, and then returns to step 102a to continue execution. In step 108, please refer to the third figure. The electric power generated by the fuel cell device 30 in normal operation is simultaneously supplied to the electric device and the secondary battery via the conversion of the booster 32 and the charging module.

In this way, it is difficult to prevent the fuel cell device 3Q from supplying power to the single power-generating device 40 alone. The power-on device 4 is a kind of system control in which the dynamic load battery of the power consumption is high and low, and the system control is increased. For example, if the power required by the device 40 is too low, the efficiency of the methanol fuel in the fuel cell device will decrease. Therefore, only the secondary battery directly supplies the power supply to the electric field. The use of the secret battery device 30 is a life. In the fuel-electric transposition 3Q _ gambling pool 20 can be used to ride Wei Wei 3 () ^ clothing for the power required for shutdown. The step is to supply power to the power device 40 in 201021359. When the current power consumption of the power device 40 is greater than the total power consumption of the fuel cell device 30, then the secondary battery 20 will directly contact the power device 4 The power is supplied to the fuel cell device 30 to supply power to the hybrid device 4A. If the total amount of power generated by the fuel cell device 3 is sufficient to cope with the current power consumption of the power unit 40, then the step is jumped. Step i〇9c is that the secondary battery 20 will supply power to the power unit 4 with the fuel cell unit 30. In steps 109a and 109c, please refer to the third figure, the control unit 21 ® controls the unit 21 _ based on the electrical signal 22a and the current power consumption signal from the battery capacity detecting module 21B. When the current power consumption is greater than the total power generation amount of the fuel cell device 30, the secondary battery 2 改变 will change from the charged state to the discharged state. At the same time, the control unit 2丨 keeps the electronic switches 23a, 23b turned on, the secondary battery 2 〇 thus supplies power to the electric device 4〇, and at the same time, the fuel cell device 30 simultaneously supplies power to the electric device 4〇, thereby achieving Power is supplied to the electric device 40 for hybrid electric power. ❺ In the step hall +, the re-powering of the secondary battery 2 能够 can make up the fuel cell device 30 can not provide the partial power, so that the excessive load of the fuel cell device 30 can be avoided, and the fuel cell device can be improved. 30 lifetime. In step 109b, when the state of the secondary battery 2 (four) is less than the secret state, the secondary battery 20 stops supplying power to the electric device. In step 109b, please refer to the third figure. Since the secondary battery 2〇 201021359 supplies power to the electric device 40, the state of charge of the secondary battery 20 continues to decrease. When the control unit 21 detects that the state of charge of the secondary battery cell (group) 24 is less than X2%, then the process proceeds to the step. Referring to the fifth figure, in the case where the control unit 21 of the secondary battery 20 performs the hybrid power supply method of the present invention, and under the power supply to the power device 4 for a long time, the state of charge 24d of the secondary battery 24 is Form a song
