Technical Field

[0001] This application relates to the technical field of battery energy storage, and more specifically, to an energy storage system.

Background Art

[0002] Currently commercially available home battery systems are installed on the ground, occupying a large amount of space. If there is a need for expansion, it is necessary to reinstall the battery system, which is very inconvenient. Or, the battery system is mounted on the wall by screwing it on. Since the battery system is heavy, the installation is very inconvenient and there is a safety risk of collapse. Current home energy storage systems, whether installed on the ground or on the wall, have the problem of having a large amount of installation wiring, which affects the aesthetics of the substrate and is very inconvenient to install.

In this specification, the schematic expressions for the above terms do not necessarily refer to the same embodiment or implementation form. And the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or implementation forms in a suitable manner.

[0020] To solve the above technical problems, as shown in FIGS. 1 and 2, the present application provides an energy storage system mounted on a substrate 3. The energy storage system includes a connection unit, a cable 2, and a plurality of battery modules 1. The cable 2 is electrically connected to the connection unit, and the plurality of battery modules 1 are provided on the substrate 3 by the connection unit and are electrically connected by the connection unit.

[0021] Specifically, as shown in FIG. 2, the energy storage system is mounted on a wall surface, a plate surface, or other carrier on the ground 6, and includes a connection unit, a cable 2, and battery modules 1. The connection unit is mounted on the surface of the substrate 3. There may be a plurality of connection units. The plurality of connection units are integrally connected in series or in parallel by the cable 2. There may be a plurality of battery modules 1. Each battery module 1 corresponds to one connection unit. The battery module 1 is electrically connected to the connection unit. After the electric energy in the battery module 1 is led out by the connection unit, it is transmitted to the electrical equipment by the cable 2.

[0022] There may be one connection unit, and all of the plurality of battery modules 1 are connected to one connection unit.

[0023] In this embodiment, by arranging a plurality of the battery modules 1, the integrated battery system is divided into a plurality of parts. Compared with the prior art, the plurality of battery modules 1 are mounted on the base body 3 by the connection unit and distributed in a unitized manner. The battery modules 1 can be mounted according to needs to achieve a flexible arrangement of the power quantity. And the connection unit can be added according to needs to increase the battery modules 1 to meet the expansion needs. The plurality of battery modules 1 are electrically connected by the connection unit, and the connection unit is connected by the cable 2 to unify the power quantities of the plurality of battery modules 1. By directly connecting the plurality of battery units, it is avoided that the wiring becomes difficult and the cleanliness of the surface of the base body 3 is affected. The damaged battery module 1 can be replaced alone to facilitate inspection and repair. Since the surface area of the plurality of battery modules 1 is larger, it is convenient for heat dissipation to avoid the temperature of the battery module 1 being too high. At the same time, the length of the battery module 1 in a single direction is reduced. When the battery module 1 is mounted on the base body 3, the force of the battery on the base body 3 per unit area is reduced to avoid the drop of the battery module 1 and the damage of the base body 3.

[0028] Specifically, the female joint 5 includes an engagement groove 51. The shape and size of the engagement groove 51 match the shape and size of the male joint 4. The male joint 4 is arranged in the engagement groove 51 so as to be engaged with the engagement groove 51, thereby connecting the male joint 4 and the female joint 5 and connecting the battery module 1 to the base body 3.

Protrusion structures corresponding to the L-shaped structures are provided at both ends of the engaging groove 51. The L-shaped structures are engaged with the protrusion structures to connect the locking mechanism and the engaging groove 51 and achieve a locking effect. The connection method between the locking mechanism and the engaging groove 51 only needs to stably fix the locking mechanism to the engaging groove 51, and is not specifically limited here.

[0032] In this embodiment, after the male joint 4 and the engaging groove 51 are engaged by arranging the locking mechanism, the locking mechanism and the engaging groove 51 are connected and locked to fix the male joint 4 to the engaging groove 51, avoiding the male joint 4 and the engaging groove 51 from falling off, making the connection between the male joint 4 and the engaging groove 51 more firm and increasing the structural stability.
