Description
Technical field
The utility model relates to the supervision field of lead-acid battery, specifically refers to a kind of test module and monitoring system of lead-acid battery.
Background technology
Lead-acid battery (lead-acid battery), is that a kind of electrode is mainly made by lead and oxide thereof, and electrolytic solution is the accumulator of sulfuric acid solution.Under lead-acid battery state-of-charge, anodal principal ingredient is brown lead oxide, and negative pole principal ingredient is plumbous; Under discharge condition, the principal ingredient of both positive and negative polarity is lead sulfate.Frenchman Pulan spy was in utility model lead-acid accumulator in 1859, experienced the development course of nearly 150 years, lead-acid accumulator is aspect theoretical research, at aspects such as product category and kind, product electric properties, all obtained significant progress, no matter be in traffic, communication, electric power, military affairs or in navigation, each economic field of aviation, lead-acid accumulator has all played indispensable vital role.According to lead acid storage battery pool structure and purposes difference, roughly battery is divided into four large classes: 1, startup lead-acid accumulator; 2, power lead-acid storage battery; 3, fixed valve-regulated sealed lead-acid batteries; 4, other class, comprises pet-valve controlled sealed lead-acid storage battery, mine lead-acid accumulator etc.
Country will strengthen financial fund supporting dynamics, and the development of state revenue industry and technological transformation special project will be paid the utmost attention to projects such as plumbous recycling utilization (lead-acid accumulator recycling) in process is assigned in project appraisal and plan; State revenue cleaner production special fund strengthens the support to lead-acid accumulator, reviver clearer production technology project; Plumbous smelting, lead-acid accumulator, reviver backward production facilities are eliminated in the state revenue prize funds support that eliminates the backward production facilities.Local industry and information-based competent authorities make full use of the special funds such as energy-saving and emission-reduction, technological transformation, medium-sized and small enterprises special campaigns are supported.The constraint of strengthening standard simultaneously and supervision and check, implement access management to lead-acid accumulator, reviver.Supervision checks, organizes energy consumption limit standard implementation status and highly energy-consuming and falls behind the special supervisors such as motor is eliminated, backward production facilities are eliminated.And according to < < about promoting the suggestion > > of lead-acid accumulator and the normal development of reviver industry, set up interagency coordination working mechanism, relevant task is implemented in the division of labor.
For lead-acid accumulator industry, only resolve the pollution problem in production link, be still nowhere near.What than production link, more likely pollute is to reclaim link.Lead-acid accumulator Professional Committee of China Institute of Electrical Engineering Technology secretary general Xu Hong says, does not obtain the discarded lead-acid accumulator of specification handles, and ratio reaches seventy percent.At present, national Ministry of Industry and Information has mentioned quite urgent schedule the problem that solves lead-acid battery recovery, but up to now, goes back neither one scheme fairly perfect, that use.Developed at present the hand-held electric conductance test instrument of first generation lead-acid battery, be mainly applicable to lead-acid battery factory, dealer and Automobile Service Factory, 4S shop.But there is more problem in the hand-held electric conductance test instrument of current lead-acid battery: the volume of manual testing device is large, belongs to specialized equipment, and price is high, test speed is slow, consumables cost is high, be applicable to maintenance factory and sell shop, carrying inconvenience, using and be difficult for the problems such as universal.
Utility model content
The purpose of this utility model is to provide a kind of test module and monitoring system of lead-acid battery, solves current hand-held lead-acid accumulator and measures the problem that volume is large, testing efficiency is low existing; Reach the object that changes method of testing, promotes the recovery of lead-acid battery.
The purpose of this utility model is achieved through the following technical solutions:
A test module for lead-acid battery, comprises
