Description

Timing parallel connection type charger

Technical field

Belong to electronic technology field.

Background technology

This enterprise has applied for security personnel's product line for the previous period, and this product have to reserce cell, otherwise when without city During electricity, protection function will become a kind of illusory, and the when of without civil power, when being probably the peak that security personnel's accident occurs the most again Wait.So reserce cell is required.And the performance of reserce cell is directly connected to the performance of entirety.

But reserce cell is necessarily to its charge maintenance, the scientific maintenance to reserce cell, it is directly connected to backup electricity The life-span in pond, with capacity.Having data to think, battery is often not to be damaged, but charges improper and damage.In security personnel's equipment Battery, belong to reserve battery, volume capacity had particular/special requirement, be equipped with and make excessive demands in common product.The most how to ensure backup Battery life and unaffected this of capacity are one of problems.

The two of problem are tool repair information statistics, and to general charger, the active part that its internal charging controls, as opened Closing audion etc. to be easily damaged, it produces fault and accounts for the fault rate ratio of whole equipment very greatly, if therefore this pipe infringement, causes Complete machine can not use.Therefore these seem common technical problem, but become the serious major issue affecting a product quality.

Because above-mentioned reason, for ensureing the performance of this enterprise apllied security personnel product, the charged in parallel unit of this enterprise The common charging method to battery and common charging circuit can not be used.

The charging method of its routine is to use single DC charging method, and such method all can make electrolyte persistently produce hydrogen Carrier of oxygen, its oxygen, under internal high pressure effect, infiltrates into negative pole and generates CDO with cadmium plate effect, cause under pole plate available capacity Fall.If employing pulse charge, and use the method filled with put and deposit, i.e. fill certain time, such as 5 seconds, just put one Fix time such as 1 second.Major part is reduced into electrolyte under discharge pulse by the oxygen that so charging process produces, and can make analysis Tolerance is substantially reduced, and reduces gassing rate and concentration polarization and ohmic polarization can be made naturally to be eliminated, thus alleviate Lead-acid accumulator intrinsic pressure, makes the pulse charge of next stage more successfully carry out, so that lead-acid accumulator can absorb More electricity.Intermittent pulse makes lead-acid accumulator have more sufficient chemical time, thus decreases lead in charging process The gassing rate of acid accumulator, the charging current that improve lead-acid accumulator can accept ability.Pulse charging method charging certain time Such as 5 seconds, stop certain time such as electric discharge 1 second, so circulate.This charging method can make lead-acid accumulator in charging process Oxygen produced by and hydrogen are under stopping charging pulse, and oxygen and hydrogen that major part separates out have been reduced into again electrolysis Liquid, this not only reduces lead-acid accumulator gassing produced by the electrolysis of internal electrochemistry side reaction water in charging process Amount, and cause the lead-acid accumulator of inefficacy to also have repair to seriously polarizing, using this charging method to mistake After the certain number of times of lead-acid accumulator discharge and recharge of effect, the capacity of lead-acid accumulator can be made gradually to recover.Press according to data introduction again The charging method of the double electric discharge of charging, or charging again stops the way filled, not only helpful to lead battery, and to some alkali electricity Pond also helps positively.

But by above-mentioned charging method, also there are technological difficulties, because the circuit of routine is the most or not conventional circuit Being the circuit filling not only but also putting, its on-off control pipe is all the emphasis of fault, if allowing switching tube be in the state of pulse, it is easier to Becoming the probability of infringement, this is one, and it two is because circuit and has the control filled, and has again the control of discharge portion (or stopping filling), Therefore the position damaged adds again one times, if therefore by traditional design, must complex circuit, newly increased trouble point, How to solve these contradictions, become new difficult point.

Along with enriching of the modern life, get more and more by the kind of the electrical equipment of battery, the security personnel studied except this enterprise Outside equipment, the most a lot of products, such as digital machine machine, mobile phone, etc., the requirement of its charger, also there is this enterprise requirements similar Place, so the research to charger, not only involves the quality of charger itself, also involves and be electrically charged asking of two aspects in pond Topic.Because a little good charging measures have positive meaning.

Low-carbon environment-friendly should be picked up from drop, should pick up from trickle, is the most just beneficial to the permanent progress and development of society.

Further illustrate:

1, operation principle explanation.

After opening power supply, all unit are started working, and in charging process, because the work of impulse generating unit, it is not Disconnected control charged in parallel unit two audion is in be opened and off-state, and what therefore charge circuit produced is pulse current.

The charge rule coexisted at charge and discharge is, after opening power supply, impulse generating unit is started working, in pulse Within one cycle, when N pipe output of vibrating is high-order, charging two audion at charged in parallel unit is opened and is filled to being electrically charged pond Electricity, on the contrary when the N pipe that vibrates exports low level, charged in parallel unit is clamped closedown, owing to, within a cycle of pulse, charging Time long, and the time stopping filling is short, so charging process is in pulse charge state.Such charging modes is the most right The scientific maintenance of battery, partial destruction is electrically charged pond simultaneously also a certain degree of restitution.

When being electrically charged pond and being not in contact with, this part display lamp does not works, because the electric current of this part display lamp is not being inserted During upper alternating current, it is derived only from battery.Now, prompting user should be clipped it is electrically charged pond.

The requirement of time is had to devise timing end unit during for the charging for the first time of some batteries, when timing terminates, Export high pressure from the high-tension ultimate outfan of low-voltage output at the end of Ding Shi, trigger and terminate performance element, to charged in parallel The base stage clamper of unit two audion, allows charged in parallel unit quit work, becomes open-circuit condition.No longer it is charged function. The base stage of the N pipe of clamper impulse generating unit vibration simultaneously, allows impulse generating unit failure of oscillation.

The most connected tiny stream resistance (in Fig. 2 2.1) is to the tiny stream electric current of the maintenance being electrically charged needed for pond provides.

2, line feature analysis.

(1), the feature of charged in parallel unit and explanation.

Charged in parallel unit is by tiny stream resistance (in Fig. 2 2.1), equipotential diode one (in Fig. 2 2.52), equipotential diode Two (in Fig. 2 2.51), equipotential resistance (in Fig. 2 2.53), charging valve one (in Fig. 2 3.1), charging trigger resistance one (Fig. 2 In 3.2), charging valve two (in Fig. 2 4.1), charging trigger resistance two (in Fig. 2 4.2) composition.

Charged in parallel unit is a most important core in this measure.Tool maintenance statistics, for all of charger In fragile elements perform the audion of Push And Release in being exactly this charge circuit.So this point is weighed by this measure Point processes, by two audions mode in parallel, as the charged in parallel unit components of this measure.

The such form of this Measure Design is from energising at the beginning, it is simply that two charging valve shareds merit consumed Rate, owing to the base stage of two charging valves is all to connect an equipotential diode to arrive ground wire again to equipotential resistance, because the base stage electricity of two pipes Press identical, so the power consumption also approximately equal that two charging valves are undertaken, be equivalent to each charging valve and assume responsibility for 1/2nd, thus Make charged in parallel unit the most reliable.

The characteristic adding audion is good, pressure height, so for the charging of high capacity cell, it is only necessary to by two charging valves It is changed to powerful audion.

(2), impulse generating unit.

The feature of this unit is mainly clapp oscillator, has frequency and adjusts, adjust with dutycycle in this circuit.

Impulse generating unit.Having 3 effects in this measure, one is to control charged in parallel unit by isolating diode, The form making charging becomes the form of pulse charge.Two is the regulation realizing dutycycle.Make the overall process of charging, fill again in realization Electricity with stop the recombination process that fills, remain optimal allocation proportion.

A, the advantage forming the principle of vibration.

The complementation that this unit of this measure is made up of with vibration P pipe (in Fig. 2 7.5) vibration N pipe (in Fig. 2 7.4) Type oscillating circuit, oscillating capacitance (in Fig. 2 11) and pulse charge and discharge branch road (in Fig. 2 9) and the adjustable charging paths of pulse (figure In 2 8.1) collectively constitute.Wherein pulse charge props up route steering diode, charging adjustable resistance limits electricity with charging paths Resistance collectively constitutes.

The principle formed is: when the P pipe collector that vibrates has output, by charge and discharge branch road and charging paths and oscillating capacitance To the base stage of vibration N pipe, thus the base current of vibration N pipe is bigger, followed by and make vibration P pipe have bigger output, thus produce Raw strong positive feedback.Thus become the first half cycle of vibration.After oscillating capacitance is fully charged, vibration N pipe is put by saturated being withdrawn into Big state, now vibration P pipe collector output voltage reduces, and now oscillating capacitance starts opposite direction electric discharge, and its course of discharge is One end of oscillating capacitance is by vibration P pipe earth resistance (in Fig. 2 7.6) to ground, then the PN of reverse bias vibration N pipe saves by greatly To the little other end returning to oscillating capacitance.Thus make the acceleration of vibration N pipe exit saturated, produce strong positive feedback, form vibration The later half cycle.

The advantage of oscillating circuit that this complementary circuit is formed: one is easily vibration, reliably, two be have in oscillatory process existing High-order output, has again low level to export, and carrying is strong, thus is prone to and the charged in parallel unit matching in this measure.Three is unit Part is few.

B, oscillating capacitance and charge and discharge branch road define the coarse adjustment of frequency of oscillation.

In impulse generating unit, it is designed with pulse charge and discharge branch road, and wherein pulse charge and discharge branch road ratio has steering diode The pulse charge branch road resistance of composition is much bigger, so the frequency of oscillation of this unit is mainly fixed by pulse charge and discharge branch road, adjusting should The resistance of branch road, just can substantially determine the frequency of this agitator, (because frequency further depends on dutycycle accurately, I.e. relevant with pulse charge branch road).The minimum resistance of adjustable resistance has been played limit value effect by the fixed resistance of pulse charge and discharge branch road.

C, that this unit of this measure is designed with dutycycle is adjustable.

The meaning of dutycycle be pulse within a cycle, the ratio of high bit time and low bit time.

Dutycycle adjustable line is mainly collectively constituted with pulse charge branch road by oscillating capacitance.

Forming adjustable principle is: when the P pipe collector that vibrates has output, when oscillating capacitance charges, its charging current Through the parallel branch of extra pulse charge and discharge branch road Yu pulse charge branch road, then flow direction oscillation N pipe base stage, due to pulse charge branch road The resistance of series connection is smaller than pulse discharge and recharge branch road, so the charging current of pulse charge branch road is leading composition.Regulation charging Adjustable resistance, can regulate dutycycle further.Pulse charge branch road limiting resistance is the restriction to adjustable minima.Work as vibration After electric capacity charging terminates, oscillating capacitance starts electric discharge and forms the later half cycle of vibration, the passage of electric discharge be pulse charge and discharge branch road with The parallel circuit of pulse charge branch road, owing in two branch roads, pulse charge branch road has the existence of steering diode, its reverse bias For infinity, so the main branch road of electric discharge is pulse discharge and recharge branch road.It should be noted that owing to vibration N pipe controls parallel connection The audion of charhing unit, the charging interval is the shortest, then the time that charged in parallel unit is opened is the longest, so this becomes this unit The adjustable charging paths that is built up in of dutycycle, and the major reason not being built up on charge-discharge circuit.Such situation is implemented To when battery is charged, within a cycle time of pulse, be charging interval length and time of discharging short, and the most right Be electrically charged pond formation is the situation of charging.

Due to impulse generating unit, to have frequency-adjustable adjustable with dutycycle, so the charging to being electrically charged pond can be real Now relative to maximum scientific.

D, the impulse generating unit logical relation to charged in parallel unit.

When N pipe output of vibrating is high-order, to charged in parallel unit not clamper, the audion of charged in parallel unit has output, Charged in parallel unit turns on, charging.

Otherwise, when the N pipe that vibrates exports low level, to charged in parallel unit clamper, the transistor base of charged in parallel unit It is clamped, without output, does not charges.

(3), timing unit and end performance element.

Regularly end unit is by intervalometer (in Fig. 2 6.0), regularly oscillation resistance (in Fig. 2 6.9), timing vibration electricity Hold (in Fig. 2 6.10), reset electric capacity (in Fig. 2 6.15), differential audion (in Fig. 2 6.17), earth resistance (in Fig. 2 6.16), ground capacity (in Fig. 2 6.11), the protective resistance (in Fig. 2 6.12) of intervalometer, the power supply voltage stabilizing of intervalometer Pipe (in Fig. 2 6.13) composition.

Intervalometer has 8 feet, the power input (in Fig. 2 6.8) of intervalometer, the i.e. the 8th foot；The ground terminal of intervalometer (in Fig. 2 6.4), the i.e. the 4th foot；The Non-follow control input (in Fig. 2 6.1) of one intervalometer, the i.e. the 1st foot；One timing The reset terminal (in Fig. 2 6.7) of device, the i.e. the 7th foot；The oscillation inputs (in Fig. 2 6.6) of one intervalometer, the i.e. the 6th foot；One The oscillation output end (in Fig. 2 6.5) of individual intervalometer, the i.e. the 5th foot；Two ultimate outfans (in Fig. 2 6.2,6.3)；Wherein One ultimate outfan is to export low-voltage, the i.e. the 2nd foot from high voltage at the end of timing, and another ultimate outfan be that timing is tied Shu Shicong low-voltage output high voltage, the i.e. the 3rd foot.

Intervalometer uses CMOS technology integrated circuit HL2203.It has the logics such as built-in agitator, frequency divider, d type flip flop Unit；Having two-phase outfan and reset and terminate timing function the most halfway, quiescent dissipation is little；Operating voltage range width.Can be square Just multiple timing, delay circuit are constituted.

Structure within intervalometer is, the 5th foot of intervalometer is oscillation output end, that is to say the outfan of interior door 1, fixed Time device the 6th foot be the input of interior door 2, when the input of door 2 is low level, the outfan of door 1 is high-order.Otherwise, when door 2 Input be high-order, the outfan of door 1 is low level.So the principle forming vibration is, after energising, because timing oscillating capacitance Uncharged, so an oscillation output end output high position, by timing oscillation resistance to the charging of timing oscillating capacitance, become vibration First half cycle, after the electricity of timing oscillating capacitance is charged to threshold value, oscillation output end has been become low level from a high position again, so timing is shaken Swing electric capacity to discharge further through timing oscillation resistance, form the later half cycle of vibration.

The oscillation principle vibrated according to this intervalometer, so this measure is that timing oscillation resistance becomes fixing with adjustable two The cascade of resistance, to realize the adjustable of frequency, ensures the adjustable in certain limit of frequency simultaneously, so adding fixing electricity Hinder the minima as adjustable resistance to limit.

Its adjustment law is that regularly oscillation resistance is the biggest, and the cycle is the longest, and timing is the longest, otherwise the shortest.Add frequency i.e. Cycle, adjustable benefit was, was adapted to the multiple needs being electrically charged pond.

Reset at intervalometer has terminated clear circuit, by resetting electric capacity, differential audion, earth resistance and ground capacity Composition, its benefit is energising every time, all once resets intervalometer, it is ensured that the accuracy of timing every time.

Due to the 3rd foot of intervalometer be timing at the end of become the ultimate outfan of high level (Fig. 2 from low level 6.3), so ought regularly terminate, a 3rd foot output high position, triggers and terminates to perform audion (in Fig. 2 10.1), make end perform The current collection of audion is the lowest, closes charged in parallel unit, allows the vibration failure of oscillation of impulse generating unit simultaneously.

(4), charging display unit.

When impulse generating unit works, when vibration P pipe (in Fig. 2 7.5) colelctor electrode has output, excitation charging display lamp (in Fig. 2 12.2) are luminous.At the end of charging, failure of oscillation, vibration P pipe collector, without output, represents that charging terminates.

This measure has a prominent advantage after implementing:

1, being the life-span substantially increasing charger by this measure one, decrease the scrappage of charger, two is to being filled Battery achieves science charging, enhances maintenance, extends the life-span being electrically charged pond, decrease scrappage.And both products, Either chargeable battery, or supporting charger, be all the commonly used kind of the modern life, so two kinds of products can be strengthened Environmental protection.Environmental protection is without minor matter, so this measure has positive effect.

2, also there is important economic worth, for the value of common electronic product, such as this series products of charger, do not having Having under famous and precious first material, so first is Value of Science & Technology, second is manually to add expense, and the 3rd is only the cost of element, and originally arranges Execute increased element limited.After this measure is implemented, can be clearly felt that one is charger life-time dilatation after user, two are Being electrically charged pond life, three is that capacity will not occur significant change, and therefore society is bound to accept, and recognizes its scientific value, The most this excellent product can replace the product of inferior quality.Owing to, in the modern life, this product purpose is extremely widespread, so can produce Significantly economic worth.

3, using the charged form filling not only but also stopping, have significant maintenance effects to being electrically charged pond, some critics claim on the net can Rechargable battery is filled bad rather than is damaged, and this measure can be closed and to be electrically charged the maximum scientific maintenance that the charging in pond is relative, special It is not to acid battery.And by such charging and discharging mode, the capacity of battery and life-span can not only be made to reduce, even make Defective cell can obtain a certain degree of recovery, so meaning is the biggest.

4, this measure excellent performance, one is the most adjustable to the ratio being electrically charged between the charging in pond, dwell time, is i.e. Dutycycle is adjustable, and two is the frequency-adjustable to pulse, and three is the most adjustable to being electrically charged pressure end, so from multi-angle multilamellar Face, adapted to variety classes model is electrically charged pond model.Another important point is can to charge jumbo battery, this As long as time the audion of charged in parallel unit Yu discharge portion is changed to large power triode.In addition this measure is not also afraid of Overcharge etc. advantage.

5, easily produce, easily debug, be well suited for minuscule-type-enterprise and produce.

6, this measure is after achieving above-mentioned main feature, has following unique distinction: circuit is more simplified, and therefore produces more Easily, operability is enhanced.

Detailed description of the invention

Fig. 1, Fig. 2, Fig. 3 example goes out the making example approach a kind of with detection that timing parallel connection type charger is implemented.

One, element is selected: all diodes are face contact diode.Oscillating capacitance in impulse generating unit is with fixed Clearing electric capacity in Shi Danyuan is electrodeless electric capacity.Intervalometer is CMOS technology integrated circuit HL2203.

Two, making sheet, welding: make circuit control panel as shown in Figure 2, and the schematic diagram of map interlinking 2 carries out circuit welding.

Three, energising checks and debugging.

1, terminate to start adjustable elements with to terminating the energising inspection of startup control unit and debugging, as shown in Figure 3.

Weld fictitious load as shown in Figure 3.

Debugging fictitious load, allows the voltage gear in circuit tester be shown as different magnitude of voltage, such as 6 volts, and 12 volts, 18 volts, 24 volts.

Supplemental instruction, is linked to be the form of adjustable stabilivolt analog circuit with an audion, when the upper inclined resistance of this pipe When uprising, the voltage of charging end to increase the bias voltage that just can puncture this pipe, makes this pipe enter magnifying state, this fictitious load three The collector voltage of pole pipe has a scope changed, thus can be modeled to a different Zener diode, thus permissible Simulate 6 volts, 12 volts, the value of 18 volts 24 volts.

2, be energized the inspection debugging with frequency to impulse generating unit.

Fictitious load in connection.The colelctor electrode of vibration P pipe, cold termination ground wire is connected with oscillographic hot junction.

After being powered up, the vibration figure that oscillograph has shows.

If showing incorrect, then it is probably element welding wrong, or quality is not to be probably oscillating capacitance (in Fig. 2 11) Good, serious drain.

Regulating frequency, the main resistance adjusted on charge and discharge branch road, make shown by oscillograph frequency meet design Requirement, its rule is that resistance is the biggest, and frequency is the slowest, otherwise the fastest.

When N pipe (in Fig. 2 7.4) that vibrates is in saturation, two audions in charged in parallel unit, without output, shake The current collection swinging P pipe (in Fig. 2 7.5) is the most high-order.The display lamp (in Fig. 2 12.2) that now charges is bright.If charged in parallel list Two audions in unit have output, then go up isolating diode welding anti-.Otherwise charging display lamp does not works.

3, the energising inspection to charged in parallel unit.

Connect fictitious load, fictitious load is adjusted to the voltage status of battery underfill.

The base stage shorted to earth of vibration N pipe (in Fig. 2 7.4) will be connect, survey the output of charhing unit, now electricity with voltmeter Pressure table has voltage to indicate.

The base stage of vibration N pipe is connect a resistance to power supply, be output as zero with voltmeter survey charhing unit.

Correct above, then explanation charhing unit is working properly with the energising of discharge cell, as incorrect, is then to connect to have Miss, or audion has damage.

4, the detection to timing end unit.

A, inspection to clear circuit.

Connect the colelctor electrode of differential audion (in Fig. 2 6.17) with circuit tester, when being initially powered up, this colelctor electrode should be zero volt, Otherwise should strengthen the capacity resetting electric capacity (in Fig. 2 6.15).

B, frequency check to intervalometer.

Fictitious load in connection.Intervalometer the 5th foot or the 6th foot is connected with oscillographic hot junction.

After being powered up, the vibration figure that oscillograph has shows, it can be seen that frequency, can calculate the cycle from frequency, In the case of oscillating capacitance is fixed, regulates adjustable resistance, frequency is transferred to design load.It is 20 countings inside this intervalometer Device, therefore can calculate timing.

C, inspection to intervalometer.

With the little resistor coupled in parallel of resistance at the two ends of frequency-adjustable branch road, frequency will become to be exceedingly fast, the 3rd of intervalometer Foot quickly has output, errorless if any output then explanation line.

5, to the detection terminating performance element.

3rd foot of end trigger resistance with intervalometer is disconnected, triggering resistance is connected on ground wire, survey parallel connection with voltmeter The output of charhing unit, has voltage to show, swings the colelctor electrode of P pipe with oscillograph vibration measuring simultaneously, has oscillogram to show, above correctly Show to charge with impulse generating unit in work.

End trigger resistance is connected on signal input on, with voltmeter survey charged in parallel unit output, Non voltage output, Swinging the colelctor electrode of P pipe simultaneously with oscillograph vibration measuring, show without figure, above correctly showing stops charging and failure of oscillation.
