Description

Technical Field

[0001] This utility model relates to the technical field of large square battery cell clamps, and more particularly to a large square battery cell clamp with an upper and lower layer structure that is compatible with single-sided and double-sided output pole energy storage. Background Technology

[0002] In recent years, with the increasing popularity of electric vehicles, the technical requirements for electric vehicle batteries, such as rapid replacement, fast charging, and battery safety, have also gradually increased. Currently, the common electric vehicle battery is placed entirely in an independent storage space, using a sensing module for temperature monitoring. This structural design still has significant shortcomings, such as poor heat dissipation performance. Although it can effectively monitor the battery, it cannot fundamentally improve heat dissipation performance and reduce safety hazards. In the automated production process of square batteries, the fixture should also change with the length of the battery after the shape is changed. In order to position the battery more conveniently without changing the fixture, it is necessary to position the battery by its length and width separately and to allow it to be inserted into the fixture channel. However, existing equipment cannot position the length and width of the battery, resulting in poor equipment adaptability and low formation efficiency. Summary of the Invention

[0003] The purpose of this invention is to solve the aforementioned technical problems by providing a novel upper and lower layer structure compatible fixture for testing large square battery cells with single-sided and double-sided terminal posts. This fixture can simultaneously test two different types of square batteries: the upper layer tests single-sided terminal post batteries, and the lower layer tests double-sided terminal post batteries. The upper and lower layers do not interfere with each other and can be controlled in a coordinated manner. The upper and lower layer arrangement is more conducive to the circulation of hot air within the chamber between the fixtures, resulting in high temperature consistency and accuracy, high temperature control accuracy for the batteries, and better control of formation temperature. This achieves the goal of integrating and testing multiple types of batteries on the same equipment, as is common in research institutes and universities, improving testing efficiency, saving costs, and reducing equipment space requirements.
