Problems solved by technology

In reality, how to check whether the new equipment meets the technical requirements agreed in advance requires on-site testing. Since the real battery pack can only do a single experiment, its cost is relatively high, and the testers need to operate close to the test during the verification process. The battery pack may explode during the test process, so the real battery pack cannot be used for verification during the test
[0005] As a result, a test load device that simulates a battery cell appears. It simply uses a steel plate or an aluminum plate as a load. Even if the extrusion force can be achieved, the extrusion force and deformation cannot be obtained because the steel plate and the aluminum plate are solid. The displacement relationship cannot satisfy the experimental

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 .

Abstract

The invention discloses a test load device for simulating a battery cell, comprising: a casing, a housing cavity is arranged in the housing; a supporting unit, the supporting unit is located in the housing cavity, and the supporting unit is connected to one of the opposite side walls of the housing . The support unit is placed in the housing, and the internal structure achieves the similar anti-extrusion and deformation characteristics of the test load device that simulates the battery cell, which avoids the accident of the tester during the experiment and reduces the cost of the test , by simulating the test load device of the battery cell, the supplier and the user can test the equipment on site, which is convenient for testing.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a test load device for simulating a battery cell. Background technique [0002] Countries around the world are paying more and more attention to environmental protection, thus vigorously supporting the development of various new energy technologies. Automobile exhaust is an important source of air pollution, and major automobile manufacturers have begun to study new energy vehicles. Electric vehicles, as a type of new energy vehicles, truly achieve zero exhaust emissions. However, electric vehicles face more potential safety hazards than traditional vehicles, and more stringent safety monitoring standards must be implemented. [0003] The power battery is one of the core components of a pure electric vehicle. It not only involves the time-consuming and maximum mileage of a full charge, but also involves the safety guarantee of the car under various complex working conditions,...
