[0002] In people's daily lives, the demand for electricity is increasing. However, due to the international situation, the depletion of fossil energy and environmental protection, some areas have problems such as excessively high electricity prices or different electricity prices during the day and night. In order to solve these problems, household energy storage systems have gradually become popular. It can store electricity when the electricity price is cheap and use it when the electricity price rises.

[0003] Nowadays, mobile power supplies and energy storage power supplies are pursuing centralized stacking of batteries to reduce the size of mobile power supplies or energy storage power supply devices, which can not only reduce costs but also make the devices look more refined and high-end. However, this method makes the internal space of the battery box extremely limited, especially for stacked mobile power supplies. There is no flow between the upper and lower battery packs, and the heat dissipation effect is very poor, which easily causes heat accumulation. Therefore, in response to this situation, the utility model proposes a new solution. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 2 As shown, the utility model provides a technical solution: a household stackable mobile power supply, comprising: a plurality of battery boxes 1 and control boxes 2, the battery boxes 1 and the control boxes 2 are stacked, a battery module 4 is arranged inside the battery box 1, and abutment frames 3 for limiting the battery module 4 are arranged on both sides of the battery module 4. By arranging the abutment frames 3 on both sides of the battery module 4, the movement range of the battery pack can be effectively limited to prevent unnecessary vibration or displacement during transportation or use, thereby protecting the safety of the battery module 4 and surrounding equipment, ensuring its stability and reliability, and also facilitating the operation of maintaining and replacing the battery module 4.

[0024] like Figure 1 and Figure 2 As shown, in order to ensure the smooth implementation of this embodiment, it is necessary to understand that each battery module 4 is provided with a number of battery packs, each group includes at least four battery blocks, the battery blocks are electrically connected in series, and the battery packs are electrically connected in parallel. By connecting the battery blocks in series, the voltage can be increased, and by connecting the battery packs in parallel, the current capacity can be increased. Such a design enables the battery module 4 to provide a more stable power output, and when a problem occurs in a certain battery, the entire system can still operate normally, and the overall performance will not be affected by the failure of a battery. In addition, this connection method can also improve the charging and discharging efficiency of the battery pack and extend the service life of the battery. The battery modules 4 between the upper and lower layers are electrically connected and can be connected by a detachable soft cable so that the upper and lower layers can be separated. After separation, the battery works normally. At the same time, when the battery module 4 fails, it is only necessary to remove the battery pack where the battery block fails, and after removal, the entire mobile power supply can be used normally in addition to battery life, and the practical effect is good.

[0025] There are multiple anti-frames 3 in the shape of a box, and a protrusion 301 extends from the top of the anti-frame 3 into the battery case 1 to press the battery block. The anti-frame 3 is not only used to limit the battery, but also has a gap between the anti-frames 3 and a certain thickness. Therefore, a gap is left between the battery block and the inner wall of the battery case 1, which can facilitate the flow of heat and provide sufficient space for the connection of lines between the upper and lower battery cases 1. The battery module 4 can be used to connect lines all around. A bottom plate 6 is provided at the bottom of the battery case 1. The length and width of the bottom plate 6 are both smaller than the length and width of the inner wall of the battery case 1. Both sides of the bottom plate 6 are connected to the battery case 1 through support plates 7. The structural setting of the bottom plate 6 allows the bottom of the battery case 1 to also have the effect of ventilation and heat dissipation, and the battery pack can also be installed. The battery pack is placed between the anti-frames 3 on both sides, and the protrusion 301 on the top of the anti-frame 3 can also press the battery pack to limit the battery pack.

[0026] like Figure 2 As shown, further, the battery box 1 and the control box 2 are both provided with a heat dissipation net 102, and the battery box 1 and the control box 2 are both provided with handle grooves 101 on both sides, which have good heat dissipation effect and are convenient for carrying.

[0027] like Figure 3 and Figure 4 As shown, with regard to this scheme, preferably, the bottom plate 6 is a grid plate-shaped plate body, and a vertically mounted partition 8 is fixed on the bottom plate 6. A gap is set between the partition 8 and the battery box 1, and a cooling fan 5 is installed in the gap. The mobile power supply may generate high temperature during operation. The heat in the battery box 1 is discharged by the fan to reduce the heat accumulation in the box. The partition 8 can also separate the fan and the battery to avoid interference between the two. The bottom plate 6 is a grid plate-shaped plate, and the box body also has a heat dissipation net 102 for heat dissipation. The overall heat dissipation effect is excellent. A limiting spacer 9 is set on the top of the battery module 4, and a hole is opened on the limiting spacer 9. The hole on the limiting spacer 9 is adapted to the protrusion on the top of the battery module 4. The thickness of the limiting spacer 9 is adapted to the gap between the battery module 4 and the inner wall of the top of the battery box 1, so that the battery module 4 can be limited on both sides and the top, effectively ensuring the stability of the battery module 4.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
