Description

Technical Field

[0001] This utility model relates to the field of batteries, and in particular to a device for simulating a battery module. Background Technology

[0002] In the research and development and production of battery modules, the verification of the tab welding process is a crucial step in ensuring battery performance and safety, typically requiring extensive and repeated experiments to optimize parameters. Traditional experimental methods directly use real battery modules for welding tests; however, battery modules are expensive and disposable, and frequent replacements lead to a sharp increase in research costs. Furthermore, the fixed size of real battery modules makes it difficult to adapt to different experimental scenarios (such as different module specifications or process verification requirements), limiting the flexibility and efficiency of experiments. While some simulation devices exist in existing technologies, their structures are often non-adjustable or their tab fixing methods are complex, failing to simultaneously meet the requirements of low cost, reusability, and high adaptability. Therefore, there is an urgent need for a device that can accurately simulate battery module dimensions, support rapid tab replacement, and possess highly adjustable characteristics to address the technical pain points of high experimental costs and poor flexibility. Utility Model Content

[0003] The purpose of this invention is to provide a simulated battery module device, specifically a low-cost, reusable, and size-adjustable simulated battery module device to replace a real battery module for tab welding experiments, solving the problems of high cost, fixed and non-adjustable size, and inconvenient tab replacement in traditional experiments.

[0004] This utility model is achieved by the following technical solution: a simulated battery module device, characterized in that it includes a tab fixing seat, an adjustable panel and a base, characterized in that: the adjustable panel is disposed on the upper end of the base, a plurality of tab fixing seats are fixed on a fixing plate, and the fixing plate is connected to the adjustable panel.

[0005] Furthermore, the electrode fixing base includes an electrode clamp body, two electrode fixing pieces, and two clamping plates. The two electrode fixing pieces are respectively disposed on both sides of the electrode clamp body, and the two clamping plates are disposed on different sides from the electrode fixing pieces. The inner side of the clamping plates is provided with an inclined surface, and the part of the electrode fixing piece that contacts the clamping plate is provided with a corresponding inclined surface. The clamping bolt connects the two clamping plates and passes through the electrode clamp body. By tightening the clamping bolt, the clamping plates move relative to each other, thereby pushing the electrode fixing pieces toward the electrode clamp body to clamp the electrode.

[0006] Furthermore, a spring is provided between the clamping plate and the main body of the electrode clamp, and the spring is sleeved on the clamping bolt.

[0007] Furthermore, the main body of the electrode clamp is provided with a through groove in the middle, and a spring is provided in the through groove to push the two electrode fixing pieces to reset.

[0008] Furthermore, the base is fixed by screws to two side plates, a support plate, and a bottom plate.

[0009] Furthermore, the adjustable panel includes an upper panel and a lower panel, which are fixed together by screws. The height of the adjustable panel can be adjusted by adjusting the height of the screws.

[0010] Furthermore, a gap is provided between the tab fixing plate and the tab clamp body for inserting the tab.

[0011] The advantages of the simulated battery module device described in this utility model include:

[0012] By using a simulation device to replace the real battery module, the consumption of expensive battery materials can be avoided. The device can be reused, and the cost of a single experiment can be reduced by more than 90%.

[0013] The base and adjustable panel are connected by multiple sets of screws, supporting vertical height adjustment to precisely match the size requirements of different battery module models and improve experimental compatibility.
