[0014] The following further details the overall solution of the present utility model in conjunction with the drawings and specific embodiments:

[0015] See Figure 1 , the structure of the specific embodiment of the present utility model includes a charging device, a DC-DC converter, a DC-AC converter, a battery charge and discharge management unit, a central controller, a built-in battery, a power display, a fast charging interface, and an emergency lighting device. The charging device and the battery charge and discharge management unit are respectively connected to the central controller. The central controller is connected to the fast charging interface through the DC-DC converter. The battery charge and discharge management unit is connected to the DC-AC converter. The built-in battery is connected to the battery charge and discharge management unit. The power display is connected to the central controller. The central controller is connected to the emergency lighting device through the DC-DC converter. In this embodiment, the central controller uses a DSP processor. The charging device includes a photovoltaic power generation device, a hand-cranked power generation device, and a foot-pedaled power generation device, all of which can be connected to the central controller.

[0016] The fast charging interface includes a USB PD protocol fast charging interface and an adaptive interface. The central controller is respectively connected to the USB PD protocol fast charging interface and the adaptive interface through the DC-DC converter. In this embodiment, the fast charging interface includes 4 USB PD protocol fast charging interfaces, which are respectively connected to the central controller through their own DC-DC converters.

[0017] The mains input is connected to the central controller through the AC-DC converter.

[0018] The battery charge and discharge management unit, the adaptive interface, the power display, the photovoltaic power generation device, the hand-cranked power generation device, and the foot-pedaled power generation device of the present utility model can all adopt existing structures.

[0019] The function descriptions of the functional modules of this utility model are as follows:

[0020] When the input is connected to a single-phase AC power grid, the voltage is converted from 110V / 220V high-voltage alternating current to variable low-voltage direct current by an AC-DC converter (built-in power adapter), and then converted to low-voltage direct current by the battery charge and discharge management unit to charge the built-in battery.

[0021] When the photovoltaic power generation device, hand-cranked power generation device, and foot-pedaled power generation device generate electricity, the battery charge and discharge management unit converts the direct current with a wide range of variations into direct current to charge the built-in battery.

[0022] When the output ports are simultaneously connected to a conventional device battery pack or various small mobile devices, the battery charge and discharge management unit supplies power and charges the electrical devices with the power of the built-in battery through each DC-DC converter and DC-AC converter.

[0023] During the charging process of the built-in battery, the central controller (DSP) realizes the maximization of the output power of the power generation unit on the one hand by combining the output characteristics of photovoltaics, hand-cranking, and foot-pedaling based on the monitoring results of the charge state of the built-in battery and the detection of the voltage circuit at the input port of the power generation unit; on the other hand, it realizes the fast charging requirement while extending the service life of the battery by combining the characteristics of the built-in battery.

[0024] During the discharge process of the built-in battery, the central controller (DSP) sets the output voltage and current commands of the corresponding DC-DC charging unit and DC-AC unit by detecting the voltage at the port of the conventional device battery pack on the output side, and realizes fast charging by combining the battery characteristics and the charging timing requirements. For the 5V voltage output of the general USB, this design adopts a type-C interface and is compatible with the full PD protocol, and the AC uses a general international standard three-phase waterproof socket to meet the short-time fast charging requirements of various small mobile devices.

[0025] The outputs of power generation units such as the mains adapter, photovoltaics, hand-cranking, and foot-pedaling generators are used to charge the built-in battery of the portable power supply device through the battery charging management unit;

[0026] The built-in battery directly charges communication devices, battery packs, and small portable mobile devices with different voltage levels through different DC-DC charging units. Its remarkable feature is that most of the energy of the power generation units needs to be stored in the battery pack first and then charge the load devices, and the number of battery charge and discharge cycles increases slightly. The advantage is that the built-in battery pack is directly connected in parallel to the DC bus, and the voltage variation range of the DC bus is relatively narrow, which helps to ensure that the DC-DC converter and DC-AC converter for charging the load operate at the optimal working point.

[0027] The technical content not specifically described in the content of this utility model and the above embodiments is the same as the prior art.

[0028] The above is only the specific implementation mode disclosed by the present utility model, but the protection scope disclosed by the present utility model is not limited thereto. The protection scope disclosed by the present utility model shall be subject to the protection scope of the claims.
