Technical Field

[0001] This utility model relates to the field of household energy storage technology, specifically to a household energy storage device. Background Technology

[0002] In recent years, with the development of new energy sources and the transformation of the power system, residential energy storage (hereinafter referred to as residential storage) has gradually become an important way to address energy supply and demand issues and ensure grid stability. When the grid is unstable, residential storage can provide timely support; when electricity supply exceeds demand, it can store electrical energy; furthermore, residential storage can store electricity during off-peak hours and release it during peak hours to generate revenue. Residential storage flexibly responds to power fluctuations, providing users with convenient electricity access and saving on energy costs.

[0003] When user-grade battery cells are performing the above functions, higher and faster charge and discharge rates are also a major requirement. High-rate charge and discharge of battery cells releases a large amount of heat, which puts a significant strain on the cell's charge and discharge performance, battery capacity, and lifespan.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] according to Figure 1 As shown, this embodiment provides a residential energy storage device, which includes a high-voltage top box 10, a bottom plate 20, a decorative panel 30, and a battery pack 40. The high-voltage top box 10 is assembled with the decorative panel 30 and the bottom plate 20 to form a residential energy storage device that can accommodate multiple battery packs 40. The battery packs 40 are stacked in the residential energy storage device. Taking this embodiment as an example, the battery packs 40 are stacked in a 2-row × 3-column configuration, with a gap of 40-60mm between each column of battery packs 40.

[0037] according to Figure 2-3 As shown, the top of the high-voltage top box 10 is provided with a floating terminal 12 and a first installation mark 15. The floating terminal 12 on the top of the high-voltage top box 10 is a reserved interface for the connection of the inverter. The first installation mark can be used to install the high-voltage top box 10 according to the mark, so as to prevent errors when assembling the household energy storage device.

[0038] The high-voltage top box 10 is in the shape of an "I" and has fans 11 on both sides. The fans 11 are fixed to the sides of the high-voltage top box 10 by brackets (not shown in the figure). The high-voltage top box 10 is provided with air ducts 16. The air ducts 16 extend from the installation position of the fans 11 to the bottom of the high-voltage top box 10. The air ducts 16 are directly opposite the gap between the battery packs 40. The heat of the battery packs 40 is discharged through the gap and then discharged from the residential energy storage device by the fans 11 through the air ducts 16.

[0039] The high-voltage top box 10 has a central groove with a connector, which includes a low-voltage connector 13 and a high-voltage connector 14. The connector is connected to the battery pack 40 via a wire harness. By setting the connector in the groove, space is left for the connector to connect to the wire harness, thus enabling connection to the battery pack 40. This design is both aesthetically pleasing and space-saving.

[0040] according to Figure 7 As shown, the high-voltage top box 10 is provided with a detachable handle 50. The handle 50 is fixed to both sides of the high-voltage top box 10 by bolts 17. When it is necessary to install or disassemble the high-voltage top box 10, the handle 50 facilitates the movement of the high-voltage top box 10, making it convenient for the installation or disassembly of the high-voltage top box 10.

[0041] according to Figure 1 As shown, the decorative panel 30 has four parts: a front decorative panel, a rear decorative panel, a left decorative panel, and a right decorative panel. The bottom of the front and rear decorative panels is provided with a first ventilation hole 31. Figure 8 As shown, the first ventilation hole 31 is connected to the gap, and the air duct 16, the gap, and the first ventilation hole 31 are connected to form a heat dissipation channel. The fan 11 removes the heat from the household energy storage device, and the cool air brought by the first ventilation hole 31 cools and dissipates heat from the battery pack 40, improving the heat dissipation effect of the battery pack 40. The top of the left and right decorative panels is provided with a second ventilation hole 32. The second ventilation hole 32 dissipates heat from the household energy storage device and also dissipates the heat generated by the fan 11.

[0042] according to Figure 4 As shown, the base plate 20 is provided with a first positioning pin 21 and a second installation mark 22. The first positioning pin 21 is used to fix the battery pack 40, and the second installation mark 22 facilitates the installation of the battery pack 40. Figure 4 It can be seen that the arrows of the second installation mark 22 are not in the same direction, indicating that the direction of the battery pack 40 has changed. The first or third column battery pack 40 and the middle column battery pack 40 share a heat dissipation channel, so that all the battery packs 40 can dissipate heat through the heat dissipation channel.

[0043] according to Figure 5-6 As shown, the top of the battery pack 40 is provided with a third mounting mark 41 and a second positioning pin 42. The third mounting mark 41 facilitates the stacking of the battery packs 40, and the second positioning pin 42 is used to fix the stacked battery packs 40. The battery pack 40 is provided with a detachable handle 50, which is fixed to both sides of the battery pack 40 by bolts. When the battery pack 40 needs to be installed or removed, the battery pack 40 can be fixed in the household energy storage device by manually or mechanically gripping the handle 50, or the battery pack 40 can be removed from the household energy storage device by manually or mechanically gripping the handle 50, which facilitates the installation or removal of the battery pack 40.

[0044] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
