Description

Technical Field

[0002] Electricity is used in all aspects of modern society, and energy storage devices are essential components in these applications. Existing energy storage devices typically house two 1P10S cylindrical 40Ah lithium titanate battery modules. However, each cylindrical module is relatively heavy, and the base plate, subjected to significant stress, can deform, necessitating reinforcement. Since sheet metal work cannot enhance the base plate's load-bearing capacity through bending, welding blocks are the only viable method. Furthermore, if the two cylindrical modules are replaced with multiple horizontally placed 1P10S 30Ah lithium titanate battery modules to meet future needs, additional horizontal support plates will be required. These new support plates must be strategically placed within the existing space of the energy storage device without obstructing module replacement. Utility Model Content

Furthermore, alternative solutions are described for some mechanisms in different embodiments, and these alternatives can be applied to other identical or similar devices or mechanisms. As long as there is no conflict, the various embodiments and features in each embodiment of this utility model can be combined with each other, and the resulting technical solutions are all within the protection scope of this utility model.

[0024] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 6 As shown, this embodiment provides an energy storage device 100 that can store electrical energy and release it to an external circuit. Specifically, it includes a housing 10, a battery compartment 20, and N support plates 30.

[0026] The battery compartment 20 is installed inside the housing 10. The battery compartment 20 includes a first side compartment wall 21, a bottom compartment wall 22 and a second side compartment wall 23 connected in sequence. The first side compartment wall 21 and the second side compartment wall 23 are arranged opposite to each other. Specifically, the first side compartment wall 21 and the second side compartment wall 23 are arranged in parallel and perpendicular to the bottom compartment wall 22.

[0027] There are N support plates of size 30, where N>0 and is a natural number, specifically N=2, meaning two support plates of size 30.

[0028] The first side wall 21 is provided with N first support positions 211 at intervals from top to bottom, and the second side wall 23 is provided with N second support positions 231 corresponding to the first support positions 211. Each support plate 30 is detachably connected to the corresponding first support position 211 and second support position 231; and the N support plates 30 are detachably connected to the bottom wall 22.

[0029] Using the aforementioned energy storage device 100, different types of battery modules can be smoothly and easily replaced for use within the battery compartment 20. For example, when horizontally assembling prismatic battery modules, typically three prismatic battery modules are used, requiring two support plates 30. First, the support plates 30 are connected to the support positions on the side wall of the compartment. Then, the prismatic battery modules are placed on the support plates 30, from top to bottom, with one support plate 30 supporting one prismatic battery module. The last prismatic battery module is placed on the bottom wall 22 of the battery compartment 20, thus completing the assembly of the prismatic battery modules within the battery compartment 20. When it is necessary to replace the prismatic battery modules with cylindrical battery modules, generally... There are two cylindrical battery modules, which are assembled vertically. After the two support plates 30 are removed from the support positions of the side compartment wall, they are connected to the bottom compartment wall 22 of the battery compartment 20. The two support plates 30 and the bottom compartment wall 22 form a load-bearing base plate of the battery compartment 20 with a three-layer sheet metal reinforcement effect. At this time, the heavier cylindrical battery module is placed on the bottom compartment wall 22 of the battery compartment 20 to prevent the load-bearing base plate (bottom compartment wall 22) from deforming. As shown above, by adjusting and connecting N support plates 30 inside the battery compartment 20, it is possible to stably assemble the battery modules vertically and horizontally inside the battery compartment 20, ensuring the normal operation of the power storage device 100.

[0030] In this embodiment, preferably, the bottom of the first side wall 21 is provided with an outwardly expanding first expansion wall 212, and the second side wall 23 is provided with an outwardly expanding second expansion wall 232 corresponding to the first expansion wall 212. The larger space formed between the first expansion wall 212 and the second expansion wall 232 can accommodate the support plate 30. When the N support plates 30 are removed from the support positions of the above-mentioned side walls and then connected to the bottom wall 22 of the battery compartment 20, the setting of the two expansion walls makes it possible for the two side walls to have enough space to accommodate the support plates 30, avoid mutual interference between components, and facilitate the connection of the N support plates 30 and the bottom wall 22 to form a load-bearing base plate of the battery compartment 20 with a multi-layer sheet metal reinforcement effect.

[0031] Furthermore, one support plate 30 is stacked on the inner wall of the bottom silo wall 22, and the remaining support plates 30 are stacked on the outer wall of the bottom silo wall 22; N support plates 30 are distributed on the inner and outer walls of the bottom silo wall 22, and the main body of the support plate 30 is closely fitted with the main body of the bottom silo wall 22, resulting in a compact, coordinated and high-strength structure.

[0032] Furthermore, one support plate 30 is detachably connected to the bottom wall 22 in the opposite direction to the remaining support plates 30; N support plates 30 are distributed on the inner and outer walls of the bottom wall 22 to fasten the bottom wall 22 together to form the load-bearing base plate of the battery compartment 20, which has a stronger load-bearing effect.

[0033] In this embodiment, preferably, each support plate 30 is provided with a first connecting edge 31, a second connecting edge 32, and a third connecting edge 33, and the bottom wall 22 is provided with a fourth connecting edge 221. See [reference needed] Figure 1 and Figure 2 Each support plate 30 has a first connecting edge 31 connected to a first support position 211 and a third connecting edge 33 connected to a second support position 231, which can stably support each square battery module 60 laterally; and see Figures 3-5 The second connecting edge 32 of the N support plates 30 is connected to the fourth connecting edge 221 of the bottom compartment wall 22, which can stably support the cylindrical battery module 70. Both the support plates 30 and the bottom compartment wall 22 are provided with connecting edges, which realize the detachable connection between the support plates 30 and the support position, as well as the detachable connection between the support plates 30 and the bottom compartment wall 22. The operation is convenient and the connection is stable.

[0034] Furthermore, the first connecting edge 31 and the third connecting edge 33 are formed by bending the body of the support plate 30 in the same direction, while the first connecting edge 31 and the second connecting edge 32 are formed by bending the body of the support plate 30 in opposite directions. As configured above, the support plate 30 can be quickly and stably connected to the first side wall 21 and the second side wall 23, while facilitating the distribution of N support plates 30 on the inner and outer walls of the bottom wall 22 to fasten the bottom wall 22 together to form the load-bearing base plate of the battery compartment 20.

[0035] In this embodiment, the power storage device 100 further includes a first fixing member 40 and a second fixing member 50. The first support position 211 is provided with a first connecting hole 211a, and the first connecting edge 31 is provided with a second connecting hole 31a. The first fixing member 40 fixes the first connecting edge 31 to the first support position 211 through the first connecting hole 211a and the second connecting hole 31a. Simultaneously, the second connecting edge 32 is provided with a third connection 32a, and the fourth connecting edge 221 is provided with a fourth connecting hole 221a. The second fixing member 50 fixes the second connecting edge 32 to the fourth connecting edge 221 through the third connection 32a and the fourth connecting hole 221a. Preferably, both the first fixing member 40 and the second fixing member 50 in this embodiment are threaded connectors; this allows for quick disassembly and connection of the support plate 30 on the support position and the bottom wall 22.

[0036] In this embodiment, preferably, the battery compartment 20 is detachably connected to M horizontal locking strips 24. Each horizontal locking strip 24 is connected at both ends to the first side wall 21 and the second side wall 23, respectively. The connection can be a snap-fit ​​connection or a threaded connection using screws; there are no specific limitations, and M>0 is a natural number. (See also...) Figure 1 The battery compartment 20 is detachably connected to a horizontal locking strip 24, see [link / reference]. Figure 3 The battery compartment 20 is detachably connected to three horizontal locking strips 24. When the battery module is assembled in the battery compartment 20, it is locked by the horizontal locking strips 24 to prevent it from falling and being damaged and rendered unusable.

[0037] Finally, it should be noted that the above description is merely the preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible changes and simple substitutions to the technical solution of this utility model using the disclosed methods and technical content without departing from the scope of the technical solution of this utility model, and these all fall within the protection scope of the technical solution of this utility model.
