Abstract
A fast charger comprises the parts of a transformer (1), a rectifier (2), a controller (3), a box etc. A charging method of chopping modulation voltage-regulation is adopted, which is that the volume of a charge current is controlled automatically according to the capacity loss degree of an electrified storage battery, and the method is scientific with the fast charging speed and has the obvious desulphurization function. The charging course does not bubble up a plurality of air bubbles, which does not damage a polar plate of the storage battery; the storage battery has long life; the charger can save electrical energy and reduce the environmental pollution, does not over charge or charge less, has good charging performance and low cost and works reliably. The charger can be used as a charging device of the storage batteries of a lead-acid battery, a nickel-cadmium or nickel-hydrogen battery, a lithium ion battery etc. and especially fit for electrifying an automobile storage battery, a dynamic storage battery of an electric automobile and the dynamic storage battery of a electric locomotive under a well.
Description
Technical field
A kind of quick charger can be used as lead acid accumulator, and nickel is particularly suitable for automobile storage battery, the usefulness of the charging of the power accumulator of the power accumulator of electric automobile and down-hole power locomotive every the charging device of storage batterys such as, Ni-MH battery and lithium ion battery.
Background technology
Popular charging device has two kinds at present, i.e. constant current charge machine and fast pulse charging machine.
1, constant current charge machine.In charging process, charging current is invariable, and following deficiency is arranged:
A, charging interval are long.Generally more than 10 hours.
B, energy consumption are big.In the later stage of charging process, occur overcharging, must increase energy consumption.
C, damage storage battery.Overcharge electric current and all be used for producing a large amount of bubbles, plate active material is come off and cause shorten the useful life of storage battery.
2, fast pulse charging machine.This charger also is interspersed with the process of discharge in charging process, that is: the charging (positive pulse)---stop filling---discharge (negative pulse)---park---charging ..., in each circulation of charging, the technical parameter of each link all has strict requirement.So fast pulse charging machine has following deficiency:
A, control technology require high.
B, complex structure, cost height.
The utility model content
It is fast that the utility model provides charging rate, neither overcharge also not owe to fill, and also simple in structure, reliable operation, the charging device that cost is low, i.e. chopping modulation voltage stabilizing quick charger.This machine partly is made of transformer (1), rectifier (2), controller (3) and cabinet etc., as shown in Figure 1.It is characterized in that: controller (3) is a chopping modulation pressurizer, its structure as shown in Figure 2, by reference voltage source (5), comparison circuit (6), circuits for triggering (7), adjust element (8) and sample circuit formations such as (9).
At the initial stage of charging, filled the terminal voltage U of storage battery (4)
0Lower, to adjust element (8) and be in normal copped wave state, then a rolling land is to charge in batteries for a ripple, and charger can provide very big charging current.This process can shorten the charging interval, promptly improves charging rate.Along with the carrying out of charging process, the increase of battery capacity, its terminal voltage U
0Constantly rising, will adjust when reaching a certain set point, is example with the lead acid accumulator, when cell tension was charged to 2.4V, charge volume reached 70～80%, and tangible bubble begins in the electrolyte to emerge, this voltage claims the bubble point, just stops charging to this, obviously owes to fill too many.If continue charging by traditional constant current charge method, a large amount of bubbles of then can emerging promptly overcharge, and will increase energy consumption, the more important thing is the damage accumulator plate, shorten storage battery useful life.The charging device that the utility model designs in order to solve " owing to fill " and " overcharging " problem exactly.When sample circuit (9) detects accumulator voltage U
0When reaching set point, after reference voltage (5) comparison, comparison circuit (6) output pick-off signal, circuits for triggering (7) do not provide triggering signal, adjust element (8) and are in cut-off state, stop charging.Stop filling after-polarization voltage and eliminate terminal voltage U
0Descend, drop to setting voltage when following,, adjust element (8) and begin conducting again and charge by a series of control.But, through moment stop fill, cut away one or several ripple.Charging once more, terminal voltage rises again, reaches set point and is stopped filling again, regulates so again and again, and charging voltage is no longer raise, and charging current is more and more littler, and sufficient after-current levels off to 0.According to the power shortage degree of being filled storage battery, control the size of charging current automatically, neither owe to fill, fill only, charging rate is fast, realizes the purpose of this utility model.
