[0035] Please refer to Figures 1 to 3 This utility model provides a multifunctional portable energy storage power supply, including a main body 1, a battery module 2, a control circuit 3, a charging module 4, and a control panel 5. The main body 1 includes a top cover 11, a side plate 12, and a bottom plate 13, which together form a hollow cavity 10. The battery module 2 is disposed within the cavity 10. The control circuit 3 is disposed within the cavity 10 and located above the battery module 2. The control circuit 3 is used to control the operation of the multifunctional portable energy storage power supply. The charging module 4 is disposed within the cavity 10 and includes a photovoltaic module 41 disposed on the inner wall of the top cover 11 and a charging control component 42 disposed above the control circuit 3. The photovoltaic module 41 is used to convert solar energy into electrical energy, and the charging control component 42 is used to convert AC power into DC power. The control panel 5 is disposed on the side plate 12 and includes a charging interface 51, which includes an AC interface 511 and a DC interface 512.
[0036] In this embodiment, the main body 1 is generally rectangular in shape and is assembled from a top cover 11, side plates 12, and a bottom plate 13. The interior of the main body 1 is a hollow receiving cavity 10, used to house and protect the battery module 2, control circuit 3, charging module 4, etc. The main body 1 can be made of engineering plastics, which can improve the strength of the main body 1, making it less susceptible to damage from external impacts and protecting the modules inside. Furthermore, engineering plastics are lightweight, reducing the overall weight of the portable energy storage power supply 100, making it easier for users to carry and improving the user experience. Of course, the above is only an example; the specific material of the main body 1 can be determined according to actual needs, and this utility model does not impose any limitations.
[0037] Please refer to Figure 3 The battery module 2 includes several cells 21 located below the control circuit 3. The charging module 4 can store electrical energy in several cells 21. When the user needs to use it, it connects to the charging interface 51 on the control panel 5 to supply power to external devices.
[0038] The control circuit 3 mainly includes a circuit board, which is located within the receiving cavity 10. For details, please refer to [reference needed]. Figure 3 The control circuit 3 is located above the battery cell 21. Its main function is to control the operation of the entire portable energy storage power supply 100, such as controlling the charging or discharging of the portable energy storage power supply 100.
[0039] Existing portable power storage devices typically use electricity for charging. When users are outdoors, especially in remote mountainous areas, deserts, or other areas without stable power grid coverage, it is difficult to find a suitable charging method once the portable power storage device runs out of power.
[0040] Therefore, please refer to Figure 3 The portable energy storage power supply 100 of this utility model has a solar charging and power supply function. Specifically, the charging module 4 is equipped with a photovoltaic module 41. When the battery module 2 is low on power, the photovoltaic module 41 can convert solar energy into electrical energy and store it in the battery module 2. When the battery module 2 is fully charged, while the battery module 2 supplies power to external loads, the photovoltaic module 41 can store part of the electrical energy converted from solar energy in the power supply module and transmit the remaining electrical energy to external devices for power supply.
[0041] In addition, please continue to refer to Figure 3 The portable energy storage power supply 100 of this utility model also has the function of mains power charging. Specifically, the charging module 4 is equipped with a charging control component 42, which can convert mains power into DC power suitable for the power supply module. When the battery module 2 is low on power and the photovoltaic panel is not working, the mains power is connected to the mains, and the mains power is converted into DC power by the charging control component 42 and stored in the battery module 2. When the battery module 2 is fully charged, the charging control component 42 can also store part of the DC power converted from mains power in the battery module 2, and transmit the other part of the DC power to external devices for power supply.
[0042] Please refer to Figure 2 To facilitate user use of the portable energy storage power supply 100, a control panel 5 is provided on the side panel 12. The control panel 5 includes a charging interface 51, a DC interface 512, and an AC interface 511, which can meet the different charging and discharging needs of users and improve the versatility and practicality of this utility model.
[0043] The beneficial effects of this utility model are as follows:
[0044] (1) By installing photovoltaic modules 41 on the inner wall of the top cover 11, the portable energy storage power supply 100 can be charged by solar energy in the presence of sunlight, thereby realizing the use of clean energy and reducing dependence on traditional mains power. It is especially suitable for outdoor scenarios where there is no mains power supply, increasing the flexibility and convenience of charging.
[0045] (2) The charging control component 42 in the charging module 4 can convert the mains power to DC power and connect to the mains power through the AC interface 511 on the control panel 5 for charging. It can quickly replenish the power of the portable energy storage power supply 100 indoors or in places with mains power sockets, ensuring convenient charging in different environments.
[0046] (3) The control circuit 3 is located above the battery module 2 and is used to control the operation of the multifunctional portable energy storage power supply. It can intelligently manage the charging and discharging process, such as monitoring the charging status, controlling the charging current and voltage, preventing overcharging and over-discharging, protecting the battery module 2, extending its service life, and ensuring the safety and stability of the charging process.
[0047] (4) The control panel 5 is equipped with a charging interface 51 including an AC interface 511 and a DC interface 512. In addition to AC charging from the mains, it can also be connected to other DC power sources for charging, such as vehicle power supply, through the DC interface 512, which further enriches the charging sources and meets the charging needs of different users in different scenarios.
[0048] In some embodiments, the photovoltaic module 41 includes a photovoltaic panel connected to the inner wall of the upper cover 11. The upper cover 11 of the main body 1 has a light inlet communicating with the receiving cavity 10 and a sealing plate adapted to the light inlet. When the photovoltaic panel is not in use, the sealing plate can block the light inlet to prevent external moisture, dust and other foreign objects from entering the receiving cavity 10 and affecting the module inside. When the photovoltaic panel is needed, the sealing plate is opened to expose the light inlet, and light is taken into the photovoltaic panel through the light inlet. The semiconductor material in the photovoltaic panel absorbs photon energy and generates current. In this way, the photovoltaic panel converts solar energy into direct current, which is then stored in the battery module 2. In addition, the photovoltaic panel is installed on the inner wall of the upper cover 11, making use of the idle space of the device. Without changing the overall size and portability of the portable energy storage power supply 100, it adds solar charging function and improves space utilization.
[0049] In some embodiments, the charging control component 42 includes an AC-DC converter board that can convert the input AC power into DC power suitable for charging the battery module 2.
[0050] The charging control component 42 receives mains power to supply power to the power module, and the mains power in my country is usually 220V AC. When external AC power is input to the charging control component 42 through the charging interface 51, the AC-DC conversion board first converts the AC power from AC to DC, which is suitable for charging the battery module 2. This makes the portable energy storage power supply 100 compatible with various AC power sources, whether it is mains power or other AC power generation equipment, thus broadening the charging sources of the energy storage power supply and improving its applicability and flexibility.
[0051] In some embodiments, the multifunctional portable energy storage power supply also includes a BMS component, which is disposed on the inner wall of the side panel 12 and is electrically connected to the control circuit 3.
[0052] The BMS component comprises a battery management chip, sensors, circuitry, and a communication interface. The battery management chip analyzes real-time data collected by the sensors to assess the state of the battery module 2, such as calculating remaining charge and health status. Furthermore, the BMS component, in conjunction with the control circuit 3, precisely controls the charging and discharging processes of the portable energy storage power supply 100 based on the state of the battery module 2 and external charging demands. For example, during charging, it ensures that the battery module 2 is charged with appropriate current and voltage to avoid overcharging; during discharging, it prevents over-discharging of the battery module 2, protecting its performance and lifespan.
[0053] The BMS component also provides safety protection for the portable energy storage power supply 100, enhancing its safety and stability. The BMS component can detect abnormal states of the battery module 2, such as overvoltage, overcurrent, overheating, and short circuits, and take corresponding protective measures, such as cutting off the circuit and stopping charging and discharging, to prevent battery damage or even safety accidents. This significantly reduces the risk of fires, explosions, and other safety accidents caused by problems with the battery module 2.
[0054] Please refer to Figure 3 The multifunctional portable energy storage power supply also includes a heat dissipation component 7, which is located inside the housing cavity 10 and is electrically connected to the control circuit 3 so as to be driven by the control circuit 3 to dissipate heat.
[0055] During the charging and discharging process, the battery module 2 and control circuit 3 within the housing cavity 10 of the portable energy storage power supply 100 continuously generate heat. The heat dissipation component 7 is electrically connected to the control circuit 3 and is controlled by the control circuit 3. When the BMS component detects that the battery module 2 is overheating, it transmits the signal to the control circuit 3. The control circuit 3 then controls the heat dissipation component 7 to operate. The heat dissipation component 7 effectively dissipates heat, reducing the overall temperature of the battery module 2 and the housing cavity 10, thus preventing the internal modules from being affected and causing safety accidents such as explosions of the portable energy storage power supply 100.
[0056] The heat dissipation component 7 includes a cooling fan 71 and a heat sink 72. The cooling fan 71 is located on the side plate 12, and the heat sink 72 is located above the control circuit 3 and is positioned directly opposite the cooling fan 71.
[0057] The main function of the cooling fan 71 is to guide airflow and remove heat. Specifically, the cooling fan 71, located on the side panel 12, makes efficient use of the space in the portable power storage device 100, reducing its overall size and improving portability. The heat sink 72, located above the control circuit 3, absorbs heat generated by the control circuit 3 and surrounding modules, reducing their temperature. Furthermore, the heat sink 72 is positioned directly opposite the cooling fan 71. When the cooling fan 71 rotates, the airflow it generates passes over the heat sink 72, carrying away the heat absorbed by the heat sink 72 and ensuring that it does not remain saturated for extended periods, allowing for continuous operation. This dual cooling system of the cooling fan 71 and the heat sink 72 significantly enhances the heat dissipation effect of the portable power storage device 100, giving it excellent heat dissipation capabilities.
[0058] In some embodiments, the heat sink 72 can be a metal material with excellent thermal conductivity, such as aluminum or copper. For example, the heat sink 72 is made of aluminum. Aluminum has excellent thermal conductivity and is lightweight. Using an aluminum heat sink 72 ensures good heat dissipation performance while maintaining portability and stability without increasing the overall weight of the portable energy storage power supply 100, thus improving safety, stability, and user experience. Of course, the above is merely an example, and specific designs can be made according to actual needs; this invention does not impose limitations.
[0059] In some embodiments, the number of cooling fans 71 is provided to be at least two, and the at least two cooling fans 71 are spaced apart on the side plate 12; the number of heat sinks 72 is provided to be at least two, and the at least two heat sinks 72 are spaced apart opposite to the at least two cooling fans 71.
[0060] Two cooling fans 71 are spaced apart on one side panel 12, which helps to create uniform airflow in different parts of the portable power storage power supply 100, better covering areas that need heat dissipation. The two heat sinks 72 facing the cooling fans 71 can quickly absorb and conduct heat from the control circuit 3 they contact onto their larger surface areas. The cool air blown out by the cooling fans 71 flows over the surface of the heat sinks 72, carrying away heat and achieving the purpose of cooling. The multiple cooling fans 71 and heat sinks 72 work together to form a relatively efficient and uniform heat dissipation system, ensuring that heat is effectively dissipated from all areas inside the portable power storage power supply 100.
[0061] In some embodiments, the multifunctional portable energy storage power supply also includes an inverter, which is disposed on the inner wall of the upper cover 11. The inverter is used to convert direct current (DC) to alternating current (AC). The main function of the inverter is to convert the DC power in the portable energy storage power supply 100 into AC power, enabling the portable energy storage power supply 100 provided by this invention to power various devices that require AC power, such as laptops, televisions, and small household appliances, greatly expanding the application range of the portable energy storage power supply 100 and improving its versatility and practicality.
[0062] The inverter is located on the inner wall of the upper cover 11, which can utilize the unused space of the upper cover 11 and avoid occupying the space of the housing cavity 10, thus ensuring that the overall size of the portable energy storage power supply 100 is reduced, making it easier for users to carry and move.
[0063] The portable energy storage power supply 100 provided by this utility model also has an emergency lighting function. For details, please refer to... Figure 2 The control panel 5 also includes a lighting component 52. The light source for this component can be LED bulbs. In emergency situations, such as power outages or outdoor nighttime activities, the LED light poles can provide immediate illumination, facilitating various operations such as finding items or checking equipment status. Furthermore, integrating the lighting function into the control panel 5 diversifies the functionality of the portable energy storage power supply 100, providing additional practical functions and improving the user experience without significantly increasing size or cost.
[0064] Please continue to refer to this. Figure 2 In this embodiment, to facilitate users' viewing of the status of the portable energy storage power supply 100 and timely access to information, the control panel 5 also includes a display screen 53. The display screen 53 is connected to the internal modules and can receive signals and display information in real time. For example, if the BMS component detects that the battery module 2 is overheating, it will display text information on the display screen 53 to remind the user. Users can also view information such as battery level and voltage through the display screen 53.
[0065] This portable energy storage power supply 100 can power not only household appliances and other devices, but also mobile devices. For details, please refer to... Figure 2 The control panel 5 also includes a USB charging port 513. When users encounter a power outage or are outdoors and their mobile devices such as phones and tablets run out of power, they can use the USB charging port 513 to provide appropriate DC power to the phones and tablets.
