Abstract
The present invention relates to a valve-controlled lead-acid storage battery charging method, adopting a three-stage type charging process, namely a constant high current limited voltage limited temperature rise charging stage, a normal constant voltage limited current charging stage and a constant low current unlimited voltage limited time charging stage. When the method of the present invention is adopted to charge a valve-controlled lead-acid storage battery, about 25 percent of charging time can be saved; charging efficiency is improved from 93.75 percent to 95.21 percent; the 100 percent DOD recycling use life span of the charged battery is improved from 500 times to 615 times.
Description
Technical field
The present invention relates to a kind of charging method of valve-control sealed lead acid battery, belong to the lead acid accumulator technical field.
Background technology
Lead acid accumulator is because low cost of manufacture, and capacity is big, and is cheap and be used widely, if but improper use, its cycle life will shorten greatly.The factor that influences the lead-acid battery life-span is a lot, and correct charging method is even more important.The syllogic charge technology of the common use constant current of valve-control sealed lead acid battery--constant voltage--floating charge is at present crossed charge and is generally 5%-20%, and the charging current of charging later stage floating charge is very little, causes the charging interval longer, generally more than 16h.Use the initial stage at battery, because the saturation of dividing plate is higher, oxygen cycle efficient is relatively low, this charging modes still is effectively, but owing to the corrosion of the separating out of gas, grid and the reasons such as redistribution of electrolyte from the dividing plate to the pole plate cause the loss of electrolyte and moisture in the barrier film, make the quantity of dividing plate hollow hole increase, oxygen cycle efficient increases, oxygen cycle has consumed a large amount of overcharge current and the electric weight that overcharges, thereby has reduced the charge efficiency of battery; When consumes power surpassed over-charging of battery power consumption certain proportion, battery will be in owed charged state, and capacity attenuation is very fast during discharge, has reduced the life-span that recycles of battery.Therefore, some battery damage, not equal to fill bad.
Summary of the invention
The technical problem to be solved in the present invention is the weak point that overcomes existing lead acid battery charge technology, provides a kind of and can save the charging interval, improves the charging method for valve sealing lead acid accumulator that charge efficiency and battery recycle the life-span.
Technical scheme of the present invention is: charging method for valve sealing lead acid accumulator adopts the syllogic charge technology, and improvements are that described syllogic charge technology was undertaken by following three charging stages:
The one, the permanent big electric current limit low voltage limit temperature rise charging stage is promptly with 0.5C
10A is charged to the 2.3V/ monomer, reduces to 0.2C to electric current
10A, temperature rise is less than 10 ℃; The 2nd, the normal modified constant-voltage charge stage is promptly with 0.2C
10A charges to electric current and reduces to 0.04C
10A, constant voltage 2.4V/ monomer; The 3rd, the not pressure limiting of permanent little electric current is prescribed a time limit the charging stage, promptly with 0.01C
10A charges to and charges into electric weight is that the charging in 105% o'clock of emitting electric weight finishes.
In the technique scheme, adopt 0.5C in first charging stage
10The big electric current of A helps to guarantee the even compactness of positive active material and interfacial structure, improves the capacity and the cycle life of pole plate, and pressure limiting is 2.3V in the charging, decomposition voltage less than water, prevent moisture loss, and the controlled current system temperature rise of adopting less than 10 ℃, thereby improve charge efficiency; Second charging stage was a transition stage, and the 3rd charging stage was adopted 0.01C
10The permanent little electric current of A than big several times of floating current commonly used at present, so just can shorten the charging interval, and total charging interval is controlled at about 12h.
Embodiment
Be example with GFMG-300 high power valve-control sealed lead acid battery below, further introduce charging method of the present invention and the influence of battery charge time, charge efficiency, cycle life.
This battery adopts the syllogic charge technology, promptly earlier charges to electric current with 150A and reduces to 60A, pressure limiting 2.3V/ monomer, temperature rise is less than 10 ℃, charge to electric current with 60A again and reduce to 12A, constant voltage 2.4V/ monomer charges to constant current 3A at last that to charge into electric weight be that the charging in 105% o'clock of emitting electric weight finishes.Discharge and recharge on μ C-XCF-200A/12V microcomputer storage battery cycle charge discharge electric tester and carry out.The discharging current of this battery circulation time is 30A, the final voltage of battery discharge is the 1.8V/ monomer, the fully charged time is 12h behind the battery discharge, save the charging interval about 25% than existing charging modes, charge efficiency brings up to 95.21% by original 93.75%, and battery 100%DOD recycles the life-span and brings up to 615 times by present 500 times.
