[0029] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0030] In a typical implementation of the present invention, Figure 1-Figure 5 As shown, a household energy storage battery system is proposed, including: a hanging ear 1, a mounting plate 2, and a battery module. The hanging ear 1 and the mounting plate 2 are both provided with a plurality of bolt holes 7. The mounting plate 2 is detachably mounted on a structure such as a wall by bolts. The hanging ear 1 is detachably connected to the mounting plate 2 and the battery module by bolts. The battery module can be hung on the mounting plate 2 and fixed under the action of the hanging ear 1, which greatly facilitates the installation of the battery module.

[0031] The battery module consists of a battery pack 5, an interface component 3 and a display component 4. In this embodiment, the battery pack 5 is composed of 16 standard structure batteries arranged in series, with a rated capacity of 5.12kWh, a rated power of 2.5kW, a voltage range of 44.8-57.6V, and is equipped with a matching battery management system. The overall size is 120*155*460mm. The battery pack 5 is installed with an interface component 3 and a display component 4. The interface component 3 is located at the bottom of the battery pack 5 in the wall-mounted state for connecting cables; the display component 4 is located on the front of the battery pack 5 in the wall-mounted state.

[0032] The battery module's main shell has rounded corners at the bends, effectively reducing stress concentration and collision damage.

[0033] Among them, the interface component 3 includes a communication interface and a power interface, and the display component 4 includes an LED display screen, which can display information such as the SOC, voltage, current and temperature of the battery pack 5 to facilitate online monitoring of the working status of the battery pack 5.

[0034] It is understandable that the specific size of the battery pack 5 is determined according to actual needs, and no excessive restrictions are made here.

[0035] The mounting plate 2 is a long plate-like structure with a thickness of 3 mm. A plurality of bolt holes 7 are provided at intervals along the width direction at both ends of the mounting plate 2 for connection with a hangable structure such as a wall by bolts. In actual installation, the mounting plate 2 is located on the back of the battery pack 5, and the two ends of the mounting plate 2 extend outward from both sides of the battery pack 5 respectively.

[0036] It can be understood that the back side described in this embodiment is based on the battery pack 5 after being wall-mounted, and the side of the battery pack 5 adjacent to the wall is its back side.

[0037] Two baffles 6 are fixed on the mounting plate 2. The two baffles 6 are fixed by welding. The baffles 6 are L-shaped structures. The two baffles 6 are arranged opposite to each other. A mounting groove (such as Figure 5 As shown), the top and inner side (i.e., the side adjacent to another baffle 6) of the mounting groove are open to facilitate the insertion of the hanging ear 1 and to support the hanging ear at the same time. The number of the mounting grooves is the same as the number of the hanging ears 1 and corresponds one to one.

[0038] The baffle 6 consists of a vertical section and a horizontal section. The vertical section of the baffle 6 is provided with a plurality of bolt holes 7 at intervals along its length direction so as to be detachably connected to the hanging ear 1 by bolts, thereby improving the installation stability of the hanging ear 1 and the battery module.

[0039] There are also two hanging ears 1, which are detachably installed on both sides of the battery pack 5 by bolts. On the one hand, a handle 12 is installed on the hanging ear 1, which can facilitate the removal and placement of the entire battery module. On the other hand, the hanging ear 1 can be inserted into the installation groove between the baffle 6 and the mounting plate 2. The hanging ear 1 is supported by the baffle 6 to prevent the battery module from slipping during the process of bolt connection between the hanging ear 1 and the baffle 6. The safety is high, and there is no need for the staff to carry the battery module during the installation of the bolts, which greatly reduces the labor intensity and facilitates the installation.

[0040] Specific as Figure 4 As shown, the hanging ear 1 is composed of a connecting plate 11 and a handle 12. The connecting plate 11 is an L-shaped plate structure. The plate thickness of the connecting plate 11 is 3 mm. The handle 12 is fixedly mounted on the connecting plate 11 by welding.

[0041] The connecting plate 11 is composed of a long plate and a short plate, which are fixed together by welding. The long plate and the short plate are perpendicular to each other. A number of bolt holes 7 are provided on the long plate and the short plate. In actual installation, the long plate is detachably connected to the battery pack 5 by bolts, and the short plate is inserted into the installation groove and detachably connected to the corresponding baffle 6 by bolts.

[0042] Among them, the back side of the short plate of the connecting plate 11 is flush with the back side of the battery pack 5 to ensure that the back side of the battery pack 5 can be attached to the mounting plate 2 after installation, and the length of the long plate of the connecting plate 11 is not greater than the thickness of the battery pack 5 to avoid the connecting plate 11 extending outward, so that the connecting plate 11 does not hinder the stacking of the battery pack 5.

[0043] It is understandable that the length of the handle 12 is not greater than the length of the connecting plate 11 , and the specific length of the handle 12 can be determined according to actual needs, and no excessive restrictions are made here.

[0044] The specific working principle is:

[0045] When the battery modules need to be stacked, two hanging ears 1 are installed on both sides of the battery modules by bolts. The installer holds the two handles 12 on the hanging ears 1 to transfer the battery modules to the designated position for stacking, so that the battery pack 5 with the display component 4 is placed upward. After the battery modules are placed, it can be chosen whether to remove the hanging ears 1.

[0046] Since the length of the connecting plate 11 is not greater than the thickness of the battery pack 5 , whether the hanging ear 1 is removed or not does not affect the stacking of the battery modules, and the use is convenient.

[0047] When the battery module needs to be wall-mounted, firstly, the mounting plate 2 is fixed to the designated wall-mounting position by bolts;

[0048] Then, the two hanging ears 1 are detachably mounted on both sides of the battery pack 5 by means of bolts, so that the back side of the short plate of the connecting plate 11 is flush with the back side of the battery pack 5;

[0049] The installer holds the two handles 12 to move the battery module as a whole to the mounting plate 2, and inserts the short plates of the connecting plate 11 on both sides of the battery pack 5 into their corresponding mounting grooves. The ear hook 1 and the battery module as a whole are supported by the baffle 6, and the installer does not need to carry the battery module for a long time. Then, the short plate of the connecting plate 11 is connected to the baffle 6 with bolts to complete the wall-mounted installation of the entire energy storage battery system.

[0050] During the process of wall-mounting the battery module, supported by the baffle 6, the installer does not need to carry the battery module, which reduces labor intensity, facilitates installation, and improves the safety of the installation process.

[0051] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
