Description

Technical Field

[0001] This invention relates to the field of battery manufacturing equipment technology, and more particularly to an integrated machine for room temperature capacity testing of double-layer soft-pack batteries. Background Technology

[0002] With the rapid development of electric vehicles, the power battery industry has been fully explored and has grown rapidly. To improve the battery density of power batteries, the country is now vigorously developing soft-pack lithium-ion batteries. All battery cells undergo rigorous testing, aging, and screening processes before leaving the factory, and battery testing fixtures are indispensable components in these processes.

[0003] During battery design and production, batteries frequently require testing equipment to examine various parameters and assess their electrical performance. In this testing process, the contact between the positive and negative terminals of the battery under test and the test points on the testing equipment is crucial. Poor contact can lead to increased contact resistance, affecting the accuracy of the test results. Therefore, the connection between the battery under test and the testing equipment places high demands on the system. During testing, fixtures are primarily used to connect the battery under test to the testing equipment, ensuring accurate transmission of information from the battery to the testing equipment.

[0004] In current battery manufacturing, due to different needs, there are various types and specifications of batteries, and the sizes of batteries of different specifications and types are also different. The distance between the positive and negative tabs of the battery varies greatly. As a result, when testing different models of batteries, it is necessary to use test fixtures corresponding to different models of batteries.

[0005] Currently, most battery testing fixtures use circular spring test probes to contact the positive and negative terminals of the battery. However, it is difficult to ensure that the circular spring test probes can make full contact with the positive and negative terminals of this type of pouch battery. Summary of the Invention
