DETAILED DESCRIPTION

[0029] Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments, however, can be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and fully convey the inventive aspects of example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and descriptions of the same or similar elements can be omitted.

[0030] The words expressing position and direction described in the present application are explained by taking the drawings as an example, but changes can also be made as needed, and the changes made are included in the protection scope of the present application.

[0031] Referring to Figures 1 to 4 , the present application discloses an energy storage power supply, comprising a box 1, a battery pack 2, a power board 3 and a fan 4.

[0032] Among them, the box 1 is internally separated into a first bin 11 and a second bin 12 (see Figure 1 and Figure 2 ), used to independently place the battery part and the inverter power part of the energy storage power supply, so as to maintain independence and isolate heat transfer from each other. As Figure 1 shown, in this example, the battery pack 2 and the power board 3 are respectively arranged in the first bin 11 and the second bin 12, and are electrically connected between the two to realize power and signal control.

[0033] It can be understood that the present application separates the battery pack 2 and the power board 3, so that the heat generated by the inverter power part of the energy storage power supply is isolated from the battery part, thereby reducing the baking of the battery part and improving the safety performance of the equipment.

[0034] On the other hand, in order to prevent the power board 3 from being overheated locally and causing performance degradation or damage, the second bin 12 of the box 1 is also configured with a fan 4 to disturb the flow (see Figure 1 and Figure 4 ), which is used to internally equalize the power board 3 and the second bin 12 to improve the heat dissipation efficiency and ensure stable operation of the equipment.

[0035] It should be noted that the energy storage power supply of this application is mainly used outdoors, therefore the entire enclosure 1 must generally be kept sealed to meet high IP protection requirements. This utility model achieves thermal isolation by separating the inverter power section and the battery section into separate compartments, and utilizes the built-in fan 4 to achieve internal temperature uniformity and noise reduction (reducing thermoelectric noise and blocking noise by the enclosure 1), which can well meet the high IP requirements and modular installation requirements.

[0036] See Figure 2 As shown, in some embodiments, a partition 5 is provided inside the housing 1, with the first compartment 11 and the second compartment 12 located on both sides of the partition 5. In this application, the partition 5 is preferably a semi-enclosed structure to facilitate the installation of the battery pack 2, and the partition 5 can be enclosed with the cover plate 14 of the housing 1 to form a closed space to ensure the heat insulation effect between the battery pack 2 and the power board 3.

[0037] Specifically, the partition 5 is made of heat-insulating material, such as silica fiber board, ceramic fiber board, etc., or the surface of the partition 5 is provided with a heat-insulating layer, such as a polyimide film layer, aluminum silicate layer, etc., without limitation.

[0038] See Figure 1 As shown, in some embodiments, a first connector 6 connected to the battery pack 2 is provided in the first compartment 11. The first connector 6 can be located on the BMS circuit board at the top of the battery pack 2, with its mating end facing the second compartment 12. Correspondingly, a second connector 7 connected to the power board 3 is provided in the second compartment 12, with its mating end facing the first compartment 11. During connection, the first connector 6 and the second connector 7 are mated and plugged in to quickly connect the battery pack 2 and the power board 3 together, realizing power and signal control.

[0039] See Figure 3 As shown, the partition 5 is provided with an opening 51 for the first connector 6 portion or the second connector 7 portion to pass through. The opening matches the first connector 6 portion or the second connector 7 portion so that the first connector 6 and the second connector 7 can be paired.

[0040] Furthermore, in some embodiments, a connector sealing ring 8 is provided inside the opening 51. The connector sealing ring 8 is used to fill the gap at the opening 51 to prevent the heat generated by the power board 3 from entering the battery pack 2, thereby affecting the heat insulation effect.

[0041] See Figure 1 and Figure 3As shown, in some embodiments, the housing 1 includes a frame 13 and several cover plates 14. The frame 13 has multiple openings 131, and each cover plate 14 is detachably mounted on a corresponding opening 131. Users can flexibly install the housing 1 and its internal components according to actual needs, meeting modular installation requirements. In this application, the housing 1 can be made of metal or plastic. Preferably, the frame 13 of the housing 1 is made of metal, and the cover plates 14 are made of plastic. This design ensures the structural strength of the housing 1 while significantly reducing the weight of the equipment, resulting in better economic efficiency.

[0042] Furthermore, the edge of the frame opening 131 is provided with a sealing groove 132 and a bolt hole 133, and a frame opening sealing ring 9 is provided in the sealing groove 132; wherein, each cover plate 14 is connected to the corresponding frame opening 131 by bolts to achieve a sealing function, thereby achieving high IP protection requirements to adapt to outdoor working conditions.

[0043] Furthermore, in each cover plate 14, at least the cover plate 14 closest to the power plate 3 has heat dissipation denticles 10 on its outer side. The heat generated by the power plate 3 can be transferred to the heat dissipation denticles 10 through the cover plate 14 closest to it, thereby improving the heat dissipation efficiency. Ideally, the cover plate 14 closest to the power plate 3 can be made of a material independent of the other cover plates 14, such as aluminum / copper, to improve thermal conductivity.

[0044] In addition, this application also discloses an outdoor energy storage system, including the above-mentioned energy storage power supply. While meeting IP protection requirements, the outdoor energy storage system can achieve thermal isolation between the inverter power section and the battery section, and achieve internal temperature uniformity and noise reduction through the built-in fan 4 turbulence.
