Explosion-proof performance detecting device with fire extinguishing function for battery production

Abstract

The invention relates to an explosion-proof performance detecting device with a fire extinguishing function for battery production, and relates to the technical field of an explosion-proof performancedetecting device for battery production. The explosion-proof performance detecting device comprises a bottom plate and a first spring plate; the upper end of the bottom plate is provided with first springs; the first spring plate is disposed at upper ends of the first springs; and a first pressure sensor is embedded in the upper end of the first spring plate. The beneficial effects of the invention are that the first spring plate is connected to the bottom plate by using the first springs, when the pressure plate starts to exert pressure to a battery and a first tray apply, the first spring plate is elastically lowered by the first springs on the bottom plate after being pressed, so that the first pressure sensor can be buffered, and when the applied pressure and the first pressure sensorpair are utilized to detect the explosion-proof performance of the battery, the first pressure sensor can be simultaneously protected to prevent the applied pressure from being excessively large to cause the first pressure sensor to be crushed.

Description

technical field [0001] The invention relates to the technical field of an explosion-proof performance detection device for battery production, in particular to an explosion-proof performance detection device with fire extinguishing function for battery production. Background technique [0002] Lithium-ion batteries have become the preferred battery for portable electronic products. This kind of battery has high capacity density and competitive price. It is expected to remain the mainstream in the market in the next few years. Explosion incidents also emerge in an endless stream, and they need to be tested for explosion-proof before producing a skin of lithium batteries. [0003] Disclosed in the Chinese Invention Patent Application Publication Specification CN107796441 A is a safety detection method for an explosion-proof lithium-ion traction battery power supply device. Inspection, inspection of the safety performance of single cells and battery packs, inspection of the pr...

[0003] Disclosed in the Chinese Invention Patent Application Publication Specification CN107796441 A is a safety detection method for an explosion-proof lithium-ion traction battery power supply device. Inspection, inspection of the safety performance of single cells and battery packs, inspection of the protection action performance of the battery management system, and inspection of the explosion-proof performance of the power supply device. Conduct a comprehensive inspection of the explosion-proof lithium-ion power battery power supply device to improve the explosion-proof performance, but it is only Use charging and temperature control to detect whether the battery will explode when charging at different temperatures, but there are many factors that affect battery explosion, temperature and overcharge are objective factors, and the entire detection device is not equipped with safety precautions. When the battery explodes, it will bring great harm
