Description

Technical Field

[0001] This utility model belongs to the field of battery module testing technology, specifically relating to a battery module for rapid reliability testing. Background Technology

[0002] Photovoltaic modules undergo frequent technological iterations and updates. Changes in the pattern of the solar cells, the number and spacing of the main grid and the fine grid all require relevant reliability tests. However, the solar cells may be further optimized during the testing cycle, so the testing needs to be rescheduled.

[0003] Currently, most battery modules used for testing are manufactured using conventional methods, which results in high testing costs. Utility Model Content

[0004] The purpose of this invention is to provide a battery module for rapid reliability testing, thereby solving the problems mentioned in the background section. The battery module provided by this invention effectively reduces testing costs.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a battery module for rapid reliability testing, comprising a backplate, battery cells, and several front glass panels arranged sequentially from bottom to top, wherein the several front glass panels are arranged at equal intervals, the battery cells are connected to the backplate through a back adhesive film, and the front glass panels are connected to the battery cells through a front adhesive film.

[0006] In this invention, the distance between two adjacent front glass panes is 10-15 mm.

[0007] Furthermore, in this utility model, the dimensions of the front glass are 240*400mm.

[0008] To achieve a voltage of 12V-14V after lamination, meeting the minimum voltage requirement of 10V for existing testing equipment, the battery module further comprises several equally spaced battery cell modules. Adjacent battery cell modules are connected via busbars. Each battery cell module comprises several half-cells. These half-cells are connected in series via solder strips.

[0009] To facilitate wiring, a junction box is further connected to the back of the back panel, and the battery cells are connected to the junction box via a busbar.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This utility model designs the traditional single piece of glass used for testing battery modules into several pieces of equally spaced front glass. While ensuring that the overall size of the battery module remains unchanged, it effectively reduces the use of glass, thereby reducing testing costs.

[0012] 2. After lamination, the battery module is sealed around its perimeter and between two adjacent front glass panels using aluminum foil sealing tape to prevent moisture from entering and affecting the test results due to lack of sealing.

[0013] 3. The battery cell of this utility model includes five battery cell modules arranged at equal intervals. Each battery cell module includes four half-cells, so that the voltage of the laminated battery module can reach 12V-14V, which meets the requirement of the minimum voltage of 10V required by existing testing equipment.

[0018] 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.

[0019] Example 1

[0020] Please see Figures 1-3 This utility model provides the following technical solution: a battery module for rapid reliability testing, comprising a backplate 5, battery cells 3, and five front glass panels 1 arranged sequentially from bottom to top. The five front glass panels 1 are arranged at equal intervals, with a spacing of 10-15mm between adjacent panels. The dimensions of each front glass panel 1 are 240*400mm. The battery cells 3 are connected to the backplate 5 via a back adhesive film 4, and the front glass panels 1 are connected to the battery cells 3 via a front adhesive film 2.

[0021] By adopting the above technical solution, this utility model transforms the traditional single piece of glass used in battery modules for testing into several equally spaced front glass panels 1. While maintaining the overall size of the battery module, this effectively reduces the amount of glass used, thereby lowering testing costs. After lamination, the battery module is sealed around its perimeter and between adjacent front glass panels 1 using aluminum foil sealing tape to prevent moisture from entering and affecting test results.

[0022] Specifically, a junction box 6 is connected to the back of the back panel 5, and the battery cell 3 is connected to the junction box 6 via a busbar 32.

[0023] By adopting the above technical solution, wiring becomes easier.

[0024] Example 2

[0025] The difference between this embodiment and Embodiment 1 is that, specifically, the battery cell 3 includes five battery cell modules 31 arranged at equal intervals, and the front glass 1 is correspondingly disposed with respect to the battery cell modules 31. Adjacent battery cell modules 31 are connected by busbars 32, and each battery cell module 31 includes four half-cells 311. The four half-cells 311 are connected in series by solder strips 312, and the half-cells 311 are selected as 182-gauge battery cells.

[0026] By adopting the above technical solution, the voltage of the laminated battery module can reach 12V-14V, which meets the requirement of the minimum voltage of 10V required by existing testing equipment.

[0027] In summary, this invention transforms the traditional single-piece glass used in battery modules for testing into several equally spaced front glass panels 1. While maintaining the overall size of the battery module, this effectively reduces the amount of glass used, thereby lowering testing costs. After lamination, the battery module is sealed around its perimeter and between adjacent front glass panels 1 using aluminum foil sealing tape to prevent moisture ingress that could affect test results. The battery cell 3 comprises five equally spaced battery cell modules 31, each module consisting of four half-cell battery cells 311. This allows the laminated battery module to achieve a voltage of 12V-14V, meeting the minimum voltage requirement of 10V for existing testing equipment.
