[0037] DETAILED DESCRIPTION

[0038] ​​​Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only, for the purpose of explanation, and are not to be understood as limiting the present application.

[0039] Reference is made below to Figures 1-9 A power supply device 10 according to an embodiment of the present application is described below, which comprises a base 11, a driving assembly 12 and a solar panel 13.

[0040] The driving assembly 12 is arranged on the base 11, and the driving assembly 12 comprises a first driving member 121 and a second driving member 122. The solar panel 13 is located on both sides of the base 11 along the width direction and is dynamically connected with the driving assembly 12, and the solar panel 13 comprises a first panel body 131 and a second panel body 132, the first panel body 131 is dynamically connected with the first driving member 121, and the end of the first panel body 131 and the end of the second panel body 132 are linked through a connecting member 133, and the connecting member 133 is dynamically connected with the second driving member 122. Wherein, the driving assembly 12 is adapted to drive the first panel body 131 and the second panel body 132 to act through the first driving member 121 and the second driving member 122 to switch the solar panel 13 between unfolding and shrinking, when the solar panel 13 is unfolded, the second panel body 132 is higher than the first panel body 131.

[0041] New energy vehicle charging relies on energy supplement facilities, such as battery swap stations, charging piles, etc., the normal operation of the energy supplement facilities highly depends on the developed power supply network, however, in the above-mentioned areas, a large amount of resources need to be additionally invested for line laying when constructing the energy supplement facilities, which increases the cost, and the later maintenance cost is high, such as line aging, natural disaster damage, etc., therefore, how to stably supply power to the energy supplement facilities such as battery swap stations and charging piles in remote areas is a technical problem.

[0042] To this end, an embodiment of the present application proposes a power supply device 10, which supplies power to the energy supplement facilities through the solar panel 13, and the solar panel 13 can be switched between unfolding and shrinking to cope with different environments, which ensures the stability and reliability of power supply.

[0043] Specifically, the power supply device 10 comprises a base 11, a driving assembly 12 and a solar panel 13. The base 11 can be installed on the upper surface of a power supply facility such as a battery swap station or a charging pile, so as to ensure that it can fully contact sunlight. Optionally, the base 11 can be detachably connected through screws or bolts, so as to facilitate subsequent maintenance and replacement of the power supply device 10. In some embodiments, the base 11 can be installed on the top of a new energy vehicle, so as to realize the function of supplying power to the vehicle. The driving assembly 12 can be arranged at the base 11, and the driving assembly 12 comprises a first driving member 121 and a second driving member 122. The solar panel 13 can be located on both sides of the base 11 along the width direction. It should be noted that the width direction can be the width direction of the base 11, and the solar panel 13 can be dynamically connected with the driving assembly 12. It can be understood that the driving assembly 12 can be used to drive the solar panel 13 to move.

[0044] Further, the solar panel 13 comprises a first panel body 131 and a second panel body 132. The first panel body 131 and the second panel body 132 can be arranged in sequence along the length direction of the base 11. The first panel body 131 is dynamically connected with the first driving member 121, and the end of the first panel body 131 and the end of the second panel body 132 are connected through a connecting member 133. The connecting member 133 can be dynamically connected with the second driving member 122. It can be understood that the first driving member 121 can drive the first panel body 131 to move relative to the base 11, and the second driving member 122 can drive the connecting member 133 to move relative to the base 11. The connecting member 133 is connected with the first panel body 131 and the second panel body 132 respectively. Therefore, the first driving member 121 and the second driving member 122 can drive the first panel body 131 and the second panel body 132 to move towards the base 11 and away from the base 11, and to rotate relative to the base 11.

[0045] The driving assembly 12 can drive the first plate body 131 and the second plate body 132 to act through the first driving member 121 and the second driving member 122 to switch the solar cell panel 13 between unfolding and shrinking. When the solar cell panel 13 is unfolded, the second plate body 132 is higher than the first plate body 131. When the solar cell panel 13 is shrunk, the solar cell panel 13 is kept horizontal with the side wall of the base 11. It needs to be noted that when the solar cell panel 13 is unfolded, the height of the second plate body 132 relative to the base 11 is higher than the height of the first plate body 131 relative to the base 11. Therefore, the first driving member 121 can drive the first plate body 131 to move, so that the second plate body 132 can be linked with the first plate body 131 through the connecting member 133. In this way, the solar cell panel 13 can be facilitated to dissipate heat, and the structural strength of the solar cell panel 13 can be enhanced. The unfolding or shrinking of the solar cell panel 13 can be related to the current external environment. For example, when the solar cell panel 13 is in a weather of gale, no sunlight, etc., the solar cell panel 13 can be shrunk to avoid being damaged by the extreme environment, so that the power supply device 10 can be self-protected. In addition, the solar cell panel 13 can be shrunk through the driving assembly 12, which can facilitate the transportation, recycling and replacement of the power supply device 10, so that the portability and versatility of the power supply device 10 can be improved.

[0046] In short, the base 11 of the power supply device 10 can be installed in a power supplementing facility such as a battery swap station and a charging pile to supply power to the power supplementing facility and meet the charging demand of the power supplementing facility. The power supply device 10 can drive the solar cell panel 13 to switch between unfolding and shrinking through the driving assembly 12, so that the solar cell panel 13 can cope with different environments and avoid being damaged by the extreme environment. In this way, the use stability and reliability of the power supply device 10 can be improved, and the power supply device 10 can stably supply power to the power supplementing facility such as the battery swap station and the charging pile.

The plurality of first cell panels 1311 can be connected in sequence. The plurality of first cell panels 1311 can be connected in series through a cable to realize power transmission. The first cell panels 1311 adjacent to each other can be rotationally connected through a first connecting shaft 1312. The first cell panels 1311 adjacent to the base 11 are drivingly connected with the first driving member 121. By arranging a plurality of first cell panels 1311, the energy absorption efficiency of the first plate body 131 can be improved, and the energy supplementing efficiency of the power supply device 10 can be improved. By arranging the first connecting shaft 1312, when the solar cell panel 13 is shrunk, the first cell panels 1311 can be rotationally arranged through the first connecting shaft 1312 and abut against the adjacent first cell panels 1311, so that the occupied space of the first plate body 131 can be reduced.

[0048] The second plate body 132 can include a plurality of second battery plates 1321, the plurality of second battery plates 1321 can be connected in sequence and realize power transmission in series by a cable, and two adjacent second battery plates 1321 can be rotationally connected through a second connecting shaft 1322, the second battery plate 1321 arranged adjacent to the base 11 is connected to the edge of the base 11 through a connecting piece 133, that is, the connecting piece 133 can be connected to the edge of the first plate body 131 close to the base 11 and the edge of the second plate body 132 close to the base 11, so as to realize linkage of the first plate body 131 and the second plate body 132. In this way, the second driving member 122 can be more easily connected to the connecting piece 133, and the length and occupied space of the second driving member 122 are shortened.

[0049] As shown in Figure 1 , in some embodiments of the present application, the power supply device 10 further includes a linkage assembly 14, the linkage assembly 14 can be arranged at the adjacent first connecting shaft 1312 and the second connecting shaft 1322, and the linkage assembly 14 can be connected with the adjacent two first battery plates 1311 or the adjacent two second battery plates 1321, and the linkage assembly 14 can link the adjacent two first battery plates 1311 or the adjacent two second battery plates 1321.

[0050] Further, as shown in Figure 3 , Figure 4 and Figure 9 , the linkage assembly 14 can include a first connecting rod 141 and a second connecting rod 142, both ends of the first connecting rod 141 are respectively connected with the adjacent first connecting shaft 1312 and the second connecting shaft 1322, the second connecting rod 142 can be two, and the two second connecting rods 142 can be arranged at the first connecting shaft 1312, the two second connecting rods 142 can extend to the adjacent two second battery plates 1321 in a direction away from each other and be connected therewith, or the two second connecting rods 142 can be arranged at the second connecting shaft 1322, the two second connecting rods 142 can extend to the adjacent two first battery plates 1311 in a direction away from each other and be connected therewith.

[0051] As shown in Figures 1-4As shown, in specific embodiments, linkage assembly 14 is configured as two, when first driving member 121 drives first solar panel 1311 to move, second driving member 122 fixes connecting member 133, due to first driving member 121 drives first solar panel 1311 to rotate relative to base 11, first driving member 121 will drive first connecting shaft 1312 to move in the process of rotation, first connecting shaft 1312 drives second connecting shaft 1322 to move through first connecting rod 141, second connecting shaft 1322 will drive a group of adjacent two second solar panels 1321 to rotate towards each other in the process of movement, finally makes two second solar panels 1321 adhere, due to linkage of first solar panel 1311 and second solar panel 1321, the movement form of first solar panel 1311 and second solar panel 1321 is same, adjacent two first solar panels 1311 rotate towards each other, complete the contraction of solar panel 13.

[0052] When the number of first solar panel 1311 and second solar panel 1321 is three, two first solar panels 1311 close to base 11 can be folded towards each other, in the process of folding, it will drive two second solar panels 1321 to move synchronously, due to the action of second linkage assembly 14, two second solar panels 1321 away from base 11 will be folded, thereby driving the corresponding first solar panel 1311 to move synchronously, complete the contraction of solar panel 13.

[0053] Among them, two linkage assemblies 14 need to be arranged symmetrically, that is, two second connecting rods 142 of linkage assembly 14 close to base 11 can extend to adjacent two second solar panels 1321 and be connected with them in the direction away from each other, two second connecting rods 142 of another linkage assembly 14 can extend to adjacent two first solar panels 1311 and be connected with them in the direction away from each other, such arrangement can ensure that solar panel 13 can form a wave-like folding state.

By configuring the first connecting rod 141 as a hollow structure, the overall weight of the linkage assembly 14 can be further reduced, thereby reducing the power output by the driving assembly 12 and reducing energy consumption. The two second connecting rods 142 are respectively located on both sides of the first connecting rod 141 along the length direction of the base 11, and can be attached to the first connecting rod 141 to limit the first connecting rod 141 and prevent it from falling off.

[0061] The charging method of the embodiment of the present application will be described below with reference to Figures 10-11

[0062] ​According to the charging method for a power supply device according to the embodiments of this application, the charging method is applied to the power supply device of the above embodiments, and the charging method may include:

[0063] S1. Detect whether the device to be charged needs charging. The power supply device first detects whether the device to be charged needs charging. That is, the power supply device can determine the current power of the device to be charged, which can also be understood as the minimum energy consumption required for the device to perform its task. The device to be charged can be a new energy vehicle, etc.

[0064] S2. When the device to be charged needs charging, obtain the minimum reserve capacity Q0 and the current capacity Q1 of the power supply device. When the power supply device needs to charge the device to be charged, the power supply device can obtain the minimum reserve capacity Q0 and the current capacity Q1 through the control system. It should be noted that the minimum reserve capacity Q0 of the power supply device can be the minimum capacity required for the power supply device to operate, ensuring that when the power supply device's capacity is insufficient, it can control the solar panel to absorb solar energy and convert it into electrical energy to realize the power supply within the power supply device. In some embodiments, the minimum reserve capacity Q0 can satisfy the relationship: Q0≤30%, where 30% can be understood as 30% of the total battery capacity.

[0065] S3. When Q0 ≥ Q1, the power supply device is controlled to charge the device to be charged; when Q0 < Q1, the power supply device is controlled to stop charging. When the minimum reserved power is greater than or equal to the current power, the power supply device can charge the device to be charged; when the minimum reserved power is less than the current power, the power supply device stops charging, so that the power supply device can retain the minimum power required for operation, so that the power supply device can charge itself by solar energy later. In some embodiments, when the power supply device's power is extremely low, a backup power source can be activated or a low-power mode can be entered to maximize the preservation of power.

[0066] In short, the charging method for a power supply device according to the embodiments of this application can be applied to a power supply device that can be installed in energy replenishment facilities such as battery swapping stations and charging piles to supply power to the energy replenishment facilities, enabling the energy replenishment facilities to charge charging equipment. Furthermore, by obtaining the minimum reserve power and current power of the power supply device, the power supply device can replenish power in a timely manner, improving the stability and reliability of the power supply device and ensuring that the power supply device can provide stable power to energy replenishment facilities such as battery swapping stations and charging piles.
