Please refer to FIG. 3, which is a schematic diagram of an energy storage unit 20 according to an embodiment of the present invention. Each energy storage unit 20 has an input terminal group 22 and an output terminal group 24 respectively disposed on opposite sides of the energy storage unit 20 . The input terminal group 22 includes an input positive terminal 221 and an input negative terminal 223 . The output terminal group 24 includes a positive output terminal 241 and a negative output terminal 243 . The input terminal group 22 is electrically connected to the human power generation module 14 and the AC charging module 16 , and the output terminal group 24 is used to connect another parallel energy storage module or any external electronic device. An external electronic device is any product that requires electrical power to maintain system operation. Because the energy storage unit 20 has two terminal groups for input and output, when the energy storage module 12 self-balances and outputs electric energy to other parallel batteries or external electronic devices, the energy storage module 12 can also receive signals from the human power generation module 14 and the external electronic device at the same time. /or the electric energy of the AC charging module 16 , that is, the energy storage unit 20 has the function of charging and discharging simultaneously.

In other words, the parallel self-balancing management circuit 28 can make the output/input voltage level of each energy storage unit 20 substantially the same as the output/input voltage level of other energy storage units 20 . Therefore, the energy storage module 12 can be charged and discharged stably and simultaneously at equal pressure.

Please refer to FIG. 6, which is a schematic diagram of the human power generation module 14 of the embodiment of the present invention. The human power generation module 14 includes a magnetic element 30 and an induction coil 32 , and the induction coil 32 is movably disposed on the magnetic element 30 . The induction coil 32 will be connected to the handle 34 as shown in FIG. 1 . The user operates the handle 34 to move the induction coil 32 relative to the magnetic element 30 , and at this time the induction coil 32 generates electric energy due to the principle of electromagnetic induction. The human power generation module 14 transmits the generated electric energy to the energy storage module 12 for storage or for external electronic devices to use. In particular, the induction coil 32 in this embodiment rotates relative to the magnetic element 30 ; but in other embodiments, the induction coil 32 can also move linearly relative to the magnetic element 30 , depending on the design of the human power generation module 14 . The power generating mechanism of the human power generating module 14 is not limited to that shown in the foregoing embodiments, and will not be described one by one here.

Please refer to FIG. 2 again, the AC charging module 16 includes a conversion element (not shown in the figure). The conversion element is an AC-DC converter. The commercial power received by the AC charging module 16 is AC power, and the energy storage unit 20 is used to store DC power. Therefore, the AC charging module 16 needs to convert the AC power into DC power through a conversion element. Generally speaking, the mains power is 100/250 volts of AC power, the AC charging module 16 of this embodiment will convert the mains power into 12V DC power, and transmit it to the energy storage module 12, so that the energy storage module 12 can stabilize And store electric energy for a long time.

The control unit 18 may be a maximum power point tracking circuit. For example, the control unit 18 will detect the power characteristics generated by the human power generation module 14, such as the main circuit DC voltage and output current, use the multiplier to calculate the combination of the voltage value and the current value to obtain the current power, and measure the human power generation module through the disturbance current. 14 Changes in output power before and after the disturbance, for example using a comparator to track the maximum power point. The generated power of the human power generating module 14 will change aperiodically due to the change of the user's operating force (corresponding to the rotation speed of the induction coil 32 ). The control unit 18 can detect the current electric power of the human power generating module 14 in real time, and compare it with the electric power of the previous moment (or memory value). By adjusting the duty cycle of the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET), the average current passing through the disturbance resistor is changed, resulting in a change in the output current/voltage, and the maximum power point is found accordingly , that is, when a power point meeting (for example, greater than) a preset threshold is found. The value of the preset threshold depends on the type of the power generation module and the environment in which it is located. In this way, the control unit 18 can make the human power generation module 14 always work at the maximum power point, so that the energy storage module 12 can be fully charged with electric energy quickly.

The solar power generation module 36 and the wind power generation module 38 are optional configurations, and each uses a maximum power point tracking circuit to collect power and charge it to the energy storage module 12 to replace or cooperate with the human power generation module 14 to generate clean electric energy. Since the generating power of the solar power generation module 36 will have non-periodical changes due to the strength of sunlight, the wind power generation module 38 will also have non-periodic changes due to the size of the wind, and the control unit 18 can detect the solar power generation module 36 and the wind power generation module 38. The characteristics of the generated electric energy are traced to the maximum value of the multiplier of the voltage value and the current value, so as to control the solar power generation module 36 and the wind power generation module 38 to always work at the maximum power point. Wherein, the solar power generation module 36 is preferably a portable foldable solar panel, and the wind power generation module 38 is preferably an external small-sized high-efficiency fan, but it is not limited thereto.

Please refer to FIG. 1 again, the portable energy storage power generation device 10 may further include a casing 40 , a control panel 42 and a light emitting element 44 . The energy storage module 12 , the human power generation module 14 and the control unit 18 are all disposed in the casing 40 . The control panel 42 is disposed on the outer surface of the casing 40 . The control panel 42 may have one or more DC battery parallel interfaces 42 a electrically connected to the input terminal group 22 of the energy storage module 12 . The DC battery parallel interface 42a is used to externally connect the solar power generation module 36 or the wind power generation module 38 to the energy storage module 12 charged by the maximum power point tracking circuit to collect power. The control panel 42 can also have a commercial power interface 42b (such as DC2.0), electrically connected to the AC charging module 16 . The control panel 42 can also have one or more DC power supply interfaces 42c and one or more DC12V output interfaces (such as inverters) 42d, which are electrically connected to the output terminal group 24 of the energy storage module 12 . The DC power supply interface 42c can be a universal serial bus (USB) transmission interface, and is usually used for charging portable electronic products such as mobile phones, or providing low-voltage DC power supply. The DC12V output interface 42d can be equipped with an inverter INVERTER (not shown in the figure). The inverter (INVERTER) converts the DC power of the energy storage module 12 into AC power, and outputs the AC power to household appliances of 100W~400W. However, the interface configuration types and related parameter settings of the control panel 42 are not limited thereto. The light-emitting element 44 is a high-brightness, high-color-rendering light-emitting diode, which has high photoelectric and color quality characteristics such as low power consumption, high color rendering index, and no flicker. The light emitting element 44 is electrically connected to the output terminal group 24 of the energy storage module 12 , and only needs to consume a very low DC power to provide required outdoor lighting.
