Lithium ion battery detection device

Abstract

The invention relates to the battery detection technology field, and particularly relates to the lithium ion battery detection device. The lithium ion battery detection device comprises a needle bed mechanism and a heat radiation mechanism; the heat radiation mechanism is positioned inside the needle bed mechanism; the needle bed comprises an upper detection needle fixing plate, a lower detection needle fixing plate and a tray supporting plate. In the invention, a plurality of lithium ion batteries are placed on a battery tray of the tray supporting plate; the upper detection needle presses downwardly under the driving of a first elevation mechanism; the upper detection needle is connected to the anode of the ion battery, and the lower detection needle fixing plate jacks up under the driving of a second elevation mechanism. As a result, the lower detection needle is connected to the cathode of the lithium ion battery for simultaneously performing formation and charge and discharge detection on the big batch of the lithium ion batteries, wherein the detection process generates excessive heat which is discharged through a heat radiation mechanism, so that the detection accuracy and safety can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery detection, in particular to a lithium ion battery detection device. Background technique [0002] At present, with the rapid development of science and technology, more and more portable electronic products appear in daily life, such as mobile phones, notebook computers, PDAs, etc., and batteries are also increasingly used in these portable electronic products. [0003] As the functions of portable electronic products are gradually improved and their uses are diversified, they are used more frequently in life, so higher requirements are put forward for the quality of the batteries used to meet the needs of use. [0004] Lithium-ion battery is a rechargeable battery, which uses carbon material as the negative electrode and lithium-containing compound as the positive electrode. There is no metal lithium, only lithium ions. It is a representative of modern high-performance batteries; it mainly relies...

AI Technical Summary

Problems solved by technology

[0005]At present, in the production of lithium-ion batteries, only after being tested can they leave the factory. After the positive and negative electrodes are clamped and tested, the detection efficiency is low, the labor intensity is high, and the labor cost is also high. In addition, a large amount of heat will be generated during the formation and charge and discharge detection of lithium ions, which may cause safety accidents and pose potential safety hazards.
