Technical Field

[0001] The present invention relates to the technical field of new energy energy storage, and particularly to a flexible photovoltaic energy storage device. Background Art

[0002] Compared with conventional power generation resources, new energy power generation has strong randomness and volatility. The large-scale grid connection of new energy will have a great impact on the safe operation of the power system, leading to difficulties in power balance. The new power system requires more flexible resources to solve the problems of wind and light consumption and volatility. The intelligent system can realize the spatio-temporal transfer of energy and enhance the flexibility of the system. In particular, new energy storage technologies represented by electrochemistry and hydrogen storage have developed significantly faster in recent years.

[0003] However, the current mainstream new energy energy storage devices are limited by bottlenecks such as rigid structure design and insufficient control intelligence, and generally have defects such as fixed form and weak adaptability. Such devices are difficult to achieve wearable integration that fits the human body surface and cannot meet the dynamic adjustment requirements in complex application scenarios, which to a certain extent restricts the in-depth application and value release of distributed energy storage.

[0028] The following further describes in detail the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] Example 1:

[0030] As shown in the attached Figure 1 to the attached Figure 7 The present invention provides a flexible photovoltaic energy storage device, including a device body 1, a magic hook tape 2 and a magic loop tape 3. The magic hook tape 2 and the magic loop tape 3 are respectively movably installed on the left and right sides of the device body 1 for wearing the device body 1 on the outside of the human body. The device body 1 is composed of a power generation unit 101, an energy storage unit 102 and a contact unit 103. The control module 1031 is electrically connected to both the sheet battery film 1011 and the battery matrix 1022.

[0031] As can be seen from the above, through the opening and closing design of the magic hook tape 2 and the magic loop tape 3, the adaptive fitting of the device body 1 to the human body curve is realized, solving the pain point of the uncomfortable wearing of rigid energy storage devices. The power generation unit 101 can continuously capture energy for power generation. The energy storage unit 102 dynamically stores the photovoltaic energy of the power generation unit 101, and the contact unit 103 makes the human body wear more comfortable. And through the integrated electrical connection of the control module 1031, the intelligent allocation of photovoltaic power generation and battery energy storage is realized.

[0032] Example 2:

[0033] As shown in the attached Figure 3 to the attached Figure 4 The present embodiment is basically the same as the previous embodiment, except that the power generation unit 101 includes a sheet battery film 1011 and a flexible connection block 1012. A plurality of the sheet battery films 1011 are arranged in an array and are diamond-shaped. Each of the sheet battery films 1011 is connected by a flexible connection block 1012. Flexible wires are arranged inside the flexible connection block 1012, and a plurality of the sheet battery films 1011 are connected in series through the flexible wires.

[0034] As can be seen from the above, the topological arrangement of several sheet-like battery films 1011 combined with the hinge design of the flexible connection block 1012 realizes the multi-directional bending ability while ensuring the photoelectric conversion efficiency. The series circuit design reduces the leakage risk through the flexible connection block 1012, significantly superior to the energy transmission stability of traditional rigid photovoltaic modules in the bent state.

[0035] Embodiment Three:

[0036] As shown in the attached Figure 5 to the attached Figure 6 figures, this embodiment is basically the same as the previous embodiment, except that the energy storage unit 102 is composed of a composite layer 1021 and a battery matrix 1022. The composite layer 1021 is composed of flexible TPU and ceramic fibers, and the battery matrix 1022 is arranged in a vertical strip.

[0037] As can be seen from the above, the composite layer structure of flexible TPU and ceramic fibers provides excellent thermal conductivity and tensile properties while achieving electromagnetic shielding. The mechanical design of the vertical strip battery matrix enables the energy storage unit to maintain elastic deformation during axial tension and still maintain a high capacity retention rate after multiple bends.

[0038] Embodiment Four:

[0039] As shown in the attached Figure 7 figures, this embodiment is basically the same as the previous embodiment, except that the contact unit 103 is composed of a control module 1031, a silicone layer 1032, and bumps 1033. The bumps 1033 are arranged in an array on the inner side of the silicone layer 1032.

[0040] As can be seen from the above, the silicone layer 1032 cooperates with the hemispherical bump 1033 array to form an air convection channel through the micro-convex structure, which not only effectively reduces the contact surface temperature but also effectively discharges the sweat of the human body. The dynamic efficiency tracking algorithm integrated in the control module 1031 combined with the distributed temperature sensing network provides stable and efficient operation for the entire device.

[0041] The embodiments of the present invention are given for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
