Embodiment 1
[0037] refer to figure 1 with figure 2 , a test load device for simulating a battery cell, comprising a housing 1, a housing chamber 11 is arranged in the housing 1, a supporting unit is arranged in the housing chamber 11, the supporting unit is connected to the side wall of the housing 1, the supporting unit and The casing 1 constitutes a test load device for simulating the battery cell for testing to test its resistance to pressure and deformation. The placement direction of the casing 1 during the test is defined as the up-down direction, and the corresponding supporting units are arranged along the up-down direction.
[0038] refer to figure 1 with figure 2 , in this embodiment, the housing 1 is a closed structure, the housing 1 is composed of a bottom plate, a top plate and a side plate, the side plate is bent to form a structure with a back-shaped cross section, and the bottom plate, the top plate and the side plate are surrounded to form an accommodating cavity 11,...
Embodiment 2
[0044] The difference from Embodiment 1 is that the arrangement of the multiple support tubes 2 is different, with one of the support tubes 2 as the center, and the other support tubes 2 are circumferentially distributed outside the central support tube 2 .
Embodiment 3
[0046] The difference from Embodiment 1 is that the structure of the second positioning unit is different. The second positioning unit includes a first positioning ring 5 and a plurality of third positioning plates 6, and the plurality of third positioning plates 6 are uniformly connected to the first positioning ring in the circumferential direction. The outer wall of a positioning ring 5, the first positioning ring 5 and a plurality of third positioning plates 6 are located between the adjacent first positioning plates 3, wherein the support tube 2 near the center passes through the first positioning ring 5, and the corresponding support The tubes 2 are located between adjacent third positioning plates 6 .
