Description

Technical Field

[0001] The utility model belongs to the field of battery testing equipment, in particular to a device based on battery shell drilling. Background Art

[0002] As an important battery safety test method, the needle penetration test has attracted much attention in the battery industry. The needle penetration test is an internal short circuit test method, which is mainly used to test the safety performance of lithium-ion batteries under internal short circuit conditions. Specifically, this test method uses a steel nail to penetrate the battery to simulate the internal short circuit of the battery, and then observe whether the battery has abnormal phenomena such as smoking, fire, and rupture. This test method can effectively evaluate the safety performance of batteries under extreme conditions and is an indispensable part of the battery research and development and production process.

[0003] Before the needle penetration test, the outer shell of the needle-pierced battery cell must be drilled to expose the battery cell protective film under the outer shell. This operation needs to just penetrate the battery shell without damaging the battery cell protective film. There is currently no corresponding equipment for this operation, and it is difficult for personnel to operate manually. It is difficult to control the force, and it is easy to pierce the battery cell and cause a short circuit, thereby causing safety risks such as battery cell fire. Utility Model Content
