Description

Technical Field

[0001] This utility model relates to the field of new energy batteries, and in particular to a stacked battery pack that facilitates cell replacement. Background Technology

[0002] New energy stacked battery packs (or stacked battery packs) refer to the process in new energy systems (such as electric vehicles and energy storage systems) where multiple battery cells are stacked in a specific arrangement to form a single battery module or pack, meeting the system's requirements for voltage, capacity, and power. This design aims to optimize space utilization, increase energy density, enhance system reliability, and facilitate management and maintenance.

[0003] Traditional stacked battery packs are widely used in the new energy field for electric vehicles, energy storage systems, and portable devices. However, with increasing demand and technological advancements, traditional stacked battery packs have revealed some significant drawbacks in practical applications. These mainly include difficulty in disassembling and replacing individual cells and poor heat dissipation. Traditional stacked battery packs typically use fixed connection methods (such as welding and bonding) to stack multiple cells together, resulting in complex operations for disassembling and replacing individual cells.

[0004] Therefore, a stacked battery pack that facilitates cell replacement is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a stacked battery pack that facilitates the replacement of battery cells, thereby achieving efficient use by conveniently replacing the battery cells in the stacked battery pack.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A stacked battery pack that facilitates cell replacement includes two cell positioning plates arranged vertically and parallel to each other.

[0008] Heat sinks are attached to the other side of both of the battery cell positioning plates.

[0009] It also includes at least two sets of first limiting members; the two sets of first limiting members are arranged laterally at intervals along the battery cell positioning plate;

[0010] The first limiting member includes an upper positioning plate and a lower positioning plate, which are respectively disposed on the side of one of the heat dissipation copper sheets and are arranged opposite each other.

[0011] It also includes four sets of second limiting members, which are spaced apart along the transverse direction of the cell positioning plate; each second limiting member includes a U-shaped clamping plate.

[0012] The two sets of second limiting members in the middle are jointly equipped with side plates, and cooling fans are mounted on the side plates.

[0013] Temperature sensors and humidity sensors are respectively installed on the sides of the two sets of second limiting members located on both sides.

[0014] Furthermore, a connecting screw is inserted between the upper positioning plate and the lower positioning plate. The connecting screw passes through the cell positioning plate and the heat dissipation copper sheet, and its bottom end is threaded with a connecting nut.

[0015] Furthermore, the second limiting member also includes a locking bolt inserted into the clamping plate, the other end of which passes through the clamping plate and is threaded with a locking nut.

[0016] Furthermore, each of the two battery cell positioning plates has corresponding holes, and the battery cell body is installed between two adjacent holes.

[0017] Furthermore, the heat dissipation copper plate has several holes.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. Through the mutual movement and cooperation of multiple structures set within the first and second limiting members, the two cell positioning plates, which are positioned vertically opposite each other, can clamp and install the cell body. Simultaneously, with the installation of the first and second limiting members, the two cell positioning plates and two heat dissipation copper plates can stably clamp and install the cell body. Similarly, when the cell body needs to be replaced, it is only necessary to remove the first and second limiting members from the cell body. Compared with the traditional integrated packaging, the cell body of this application can be easily disassembled by simply removing and installing the first and second limiting members, without complicated operating steps. At the same time, the faulty cell body can be replaced individually without disassembling the entire battery pack, saving time and labor costs.

[0020] 2. The cooling fan installed on the side of the side plate can achieve efficient heat dissipation of the battery cell body, thereby further improving the heat dissipation capacity of the battery cell body when stacked; during use, the cooling fan can dissipate heat in time to prevent the battery cell from overheating, and improve the stability and safety of the system.

[0041] In this embodiment, after the cell positioning plate 1 has finished clamping the cell body 2, the user can install the upper positioning plate 41 and the lower positioning plate 42 on the two cell positioning plates 1, and at the same time, let one end of the connecting screw 43 pass through the upper positioning plate 41 and the lower positioning plate 42, and then tighten the connecting nut 44 on the bottom end of the connecting screw 43. At this time, through the clamping between the upper positioning plate 41 and the lower positioning plate 42, the two cell positioning plates 1 and the two cell bodies 2 can stably clamp and install the cell body 2.

[0042] Furthermore, the connecting nut 44 can be used to limit the movement of the connecting screw 43; simultaneously, as in the embodiment... Figure 2As shown, the top of the connecting screw 43 is integrally provided with a nut. In use, the battery cell positioning plate 1 and the heat sink copper plate 3 are provided with through holes for the connecting screw 43 to pass through, and the through holes are located away from the installation area of ​​the battery cell body 2.

Then, the user passes the locking bolt 52 through the clamping plate 51 and uses the locking nut 53 to lock the locking bolt 52. At this time, the battery cell positioning plate 1 and the heat dissipation copper plates 3 are clamped by the four sets of second limiting members 5, and the machine can further complete the stable installation of the battery cell body 2.

[0049] In this embodiment, when the user needs to install the battery cell body 2, firstly, several battery cell bodies 2 are vertically inserted into the bottom battery cell positioning plate 1 in a rectangular array, and at the same time, the bottom end of the battery cell body 2 is inserted into the hole of the battery cell positioning plate 1. Then, another battery cell positioning plate 1 is pressed onto the top of several battery cell bodies 2.

The two heat sink copper plates 3 and the two battery cell positioning plates 1 can be clamped by the U-shaped clamping plate 51. Then the user passes the locking bolt 52 through the clamping plate 51 and uses the locking nut 53 to lock the locking bolt 52. At this time, by clamping the battery cell positioning plate 1 and the heat sink copper plates 3 with the four sets of second limiting members 5, the machine can further complete the stable installation of the battery cell body 2.

[0057] Step 4: When the user needs to replace the battery cell body 2, simply unscrew the locking nut 53 and the connecting nut 44 to disassemble the first limiting member 4 and the second limiting member 5. At this time, the two heat dissipation copper plates 3 and the two battery cell positioning plates 1 can be disassembled. Then the user can replace the single battery cell body 2.
