Description

A kind of lithium battery leak test plant
Technical field
The present invention relates to a kind of lithium battery leak test plant, belong to detection apparatus field.
Background technology
" lithium battery " is a class by lithium metal or lithium alloy is negative material, the battery using non-aqueous electrolytic solution.By The most active in the chemical characteristic of lithium metal so that the processing of lithium metal, to preserve, use, the highest to environmental requirement.So, Lithium battery is not the most applied.Along with the development of science and technology, present lithium battery has had become as main flow.
Lithium battery is broadly divided into two classes: lithium metal battery and lithium ion battery.Lithium ion battery does not contains metallic state Lithium, and can charge.5th generation product lithium metal battery of rechargeable battery was born in 1996, its safety, ratio Capacity, self-discharge rate and the ratio of performance to price are superior to lithium ion battery.Owing to the high-tech of himself requires to limit, only have now The company of a few countries is producing this lithium metal battery.
The advantage of lithium battery is as follows:
Energy comparison is high.There is high storage energy density, reached 460-600Wh/kg, be about 6-7 times of lead-acid battery;
Service life is long, can reach more than 6 years service life, and LiFePO 4 is the battery 1C(100%DOD of positive pole) discharge and recharge, There is the record that can use 10,000 times;
Rated voltage is high (monomer running voltage is 3.7V or 3.2V), approximates 3 NI-Gs or the series electrical of nickel-hydrogen chargeable cell Pressure, it is simple to composition battery supply group;Voltage can be adjusted to by lithium battery by the technology of a kind of novel lithium battery pressure regulator 3.0V, with the use of applicable small electric apparatus.
Possessing high power endurance, ferrous phosphate lithium ion battery the most used for electric vehicle can reach 15-30C and fill The ability of electric discharge, it is simple to the Acceleration of starting of high intensity;
Self-discharge rate is the lowest, and this is one of the most prominent superiority of this battery, typically can accomplish below 1%/moon, less than ni-mh electricity The 1/20 of pond;
Lightweight, under same volume, weight is about the 1/6-1/5 of plumbic acid product;
High/low temperature strong adaptability, can be at-20 DEG C--uses in the environment of 60 DEG C, and through technologic process, can be at-45 DEG C Use under environment;
Environmental protection, no matter producing, using and scrap, does not all contain, does not the most produce the poisonous and harmful huge sum of moneys such as any lead, hydrargyrum, cadmium Belong to element and material.
Lithium battery, due to its special characteristic, is sampled detection before needing to dispatch from the factory, and current detection equipment is the most backward, Detecting comparatively laborious, relatively big by manual detection quantities, detection accuracy is the highest.
Summary of the invention
The present invention is directed to above-mentioned deficiency and provide a kind of lithium battery leak test plant.
The present invention adopts the following technical scheme that
A kind of lithium battery leak test plant of the present invention, including platform, vacuum leak hunting head, monitor station, sensor unit;Described Platform in be provided with placement standby inspection lithium battery, standby inspection lithium battery be arranged over vacuum leak hunting head, vacuum leak hunting head is arranged in inspection On scaffold tower, in monitor station, it is provided with sensor unit.
Lithium battery leak test plant of the present invention, described sensor unit is pressure sensor unit.
Lithium battery leak test plant of the present invention, in described platform, bottom is provided with spacing block.
Lithium battery leak test plant of the present invention, is provided with the groove placing spacing block in described platform.
Lithium battery leak test plant of the present invention, is provided with control unit in described monitor station.
Beneficial effect
The lithium battery leak test plant that the present invention provides, reduces manual detection fault rate, further enhancing the accuracy of detection.
The lithium battery leak test plant of the offer of the present invention, can detect according to the lithium battery equipment of different size, improves The level of application of this equipment.
