The frame body includes a left frame, a right frame, multiple connecting pipes, and multiple fasteners. One end of each connecting pipe is fixedly connected to the left frame via the fastener, and the other end is fixedly connected to the right frame via another fastener. Multiple support frame groups are provided inside the frame body, and the multiple support frame groups are spaced apart along the height direction of the frame body to support the box-type batteries.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 4The vertical stacked energy storage device shown includes a frame body 1 and multiple box-type batteries 2. The frame body 1 includes a left frame 11, a right frame 12, multiple connecting pipes 14 and multiple fasteners 15. One end of each connecting pipe 14 is fixedly connected to the left frame 11 through the fastener 15, and the other end is fixedly connected to the right frame 12 through another fastener 15. Multiple support frame groups 13 are provided inside the frame body 1. The multiple support frame groups 13 are distributed at intervals along the height direction of the frame body 1 to support the box-type batteries 2. Since one end of the connecting pipe 14 is fixedly connected to the left frame 11 by a fastener 15, and the other end is fixedly connected to the right frame 12 by another fastener 15, when assembling the frame body 1, it is only necessary to splice the left frame 11, the right frame 12, and the connecting pipe 14, and then fix them together with the fastener 15. When disassembling the frame body 1, it is only necessary to remove the fastener 15 to complete the disassembly of the frame body 1. Assembly and disassembly are very convenient. In addition, multiple support frame groups 13 are distributed at intervals along the height direction of the frame body 1 to support the box-type battery 2, so that the box-type battery 2 is stacked along the height direction, occupying a small area. Different numbers of box-type batteries 2 can also be stacked to meet different user needs. The box-type battery 2 is a lithium iron phosphate plug-in battery.

[0025] As a specific implementation and not a limitation, the support frame assembly 13 includes a left support frame 131 disposed on the left frame 11 and a right support frame 132 disposed on the right frame 12. The left frame 11 has first connecting plates 111 on both sides, and the two ends of the left support frame 131 are respectively fixed to the two first connecting plates 111. The right frame 12 has second connecting plates 121 on both sides, and the two ends of the right support frame 132 are respectively fixed to the two second connecting plates 121. The first connecting plate 111 is a metal plate with mounting holes, which is set along the height direction of the left frame 11. In addition, the left support frame 131 also has through holes at both ends. After aligning the mounting holes with the through holes, the left support frame 131 can be installed on the left frame 11 by passing screws through the through holes and mounting holes. The bottom of the left support frame 131 extends to form an L-shaped frame. The box-type battery 2 abuts against the L-shaped frame formed by the bottom extension of the left support frame 131, thereby supporting the box-type battery 2. The right support frame 132 is installed in the same way as the left support frame 131. The left support frame 131 and the right support frame 132 correspond one-to-one and are parallel, together supporting the box-type battery 2.

[0026] Furthermore, to make the main frame 1 more stable, a reinforcing plate 16 is provided between the left frame 11 and the right frame 12, and the reinforcing plate 16 is inclined. There are three reinforcing plates 16, and the reinforcing plates 16, together with the left frame 11 and the right frame 12, form multiple triangles, thereby making the main frame 1 more stable.

[0027] As a specific implementation and not a limitation, multiple connecting pipes 14 are respectively disposed at the four corners of the frame body 1, and perpendicular to the left frame 11 and the right frame 12. The first end of each connecting pipe 14 is connected to one corner of the left frame 11, and the other end is connected to one corner of the right frame 12, together forming a cuboid or cube, preferably a cuboid.

[0028] Furthermore, to better assemble and fix the frame body 1 using the fastener 15, the fastener 15 is triangular. One side of the fastener 15 is fixedly connected to the connecting pipe 14, and the other side is fixedly connected to the left frame 11 or the right frame 12. Since the fastener 15 is triangular, and specifically a right-angled triangle, one side of the right-angled triangle is attached to the connecting pipe 14, and the other side is attached to the left frame 11 or the right frame 12. The fastener 15 is then fixed to the connecting pipe 14, the left frame 11, and the right frame 12 respectively using screws, thereby achieving fixation.

[0029] As a specific implementation and not a limitation, for the joint management of the box-type batteries 2, a controller module 3 is included. The controller module 3 is mounted on the support frame assembly 13, and multiple box-type batteries 2 are electrically connected to the controller module 3. The controller module 3 includes a first quick-connect terminal 31. Each box-type battery 2 includes a battery housing 21, a second quick-connect terminal 23, and a battery pack 22 disposed within the battery housing 21. One end of the battery pack 22 is connected to one end of the second quick-connect terminal 23, and the other end of the second quick-connect terminal 23 is electrically connected to the first quick-connect terminal 31. The control module 3 integrates a battery management system (BMS), which can monitor and control each box-type battery 2 individually, avoiding catastrophic impacts of a single box-type battery 2 on the entire energy storage device. In this application, each box-type battery 2 has two second quick-connect terminals 23, which are electrically connected to the positive and negative terminals of the battery pack 22, respectively. Additionally, the second quick-connect terminals 23 are electrically connected to the first quick-connect terminals 31 via wires. The box-type batteries 2 are connected in series or parallel via wires.

[0030] Furthermore, in order to monitor multiple box-type batteries 2 simultaneously, the controller module 3 is also provided with a first communication terminal 32, and each box-type battery 2 is provided with a second communication terminal 24. The first communication terminal 32 is connected to the second communication terminal 24. The first communication terminal 32 and the second communication terminal 24 are connected through a communication line for communication, enabling the controller module 3 to monitor the working status and condition of each box-type battery 2 in real time.

[0031] Furthermore, the side wall of the battery box 21 is provided with a limiting plate 25. When the box-type battery 2 is inserted into the frame body 1, the limiting plate 25 abuts against the frame body 1 to restrict the movement of the frame body 1.

[0032] As one specific implementation and not a limitation, to support the frame body 1, the frame body 1 also includes a plurality of support feet 17 disposed at the bottom of the frame body 1. The plurality of support feet 17 are respectively disposed at the four corners of the frame body 1. The support feet 17 are height-adjustable. When a height adjustment is needed, the nuts on the support feet 17 are loosened, the support feet 17 are adjusted to a certain length, and then the nuts are tightened to adjust the height of the support feet 17. In another embodiment, the support feet 17 can be replaced with casters. By having the casters disposed at the bottom of the frame body 1, the vertical stacked energy storage device has better mobility and greater flexibility.

[0033] The specific working principle of this energy storage device is as follows:

[0034] During charging, lithium ions are extracted from the positive electrode material in battery pack 22, migrate through the electrolyte to the negative electrode material of battery pack 22, and embed themselves into the lattice structure of the negative electrode. Each box-type battery 2 undergoes an independent charging and discharging process, which is connected in series with the controller module, enabling the entire energy storage device to work collaboratively.

[0035] During discharge, lithium ions return from the negative electrode to the positive electrode, while electrons flow from the negative electrode to the positive electrode through an external circuit, thus outputting frame energy. Connecting the box-type batteries 2 in series can increase the total voltage of the energy storage device; connecting them in parallel can increase the total capacity of the energy storage device.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
