Pulse charging and discharging type environmental protection charger

Technical field

Belong to electronic technology technical field.

Background technology

This enterprise is applying for security personnel's product line for the previous period, and this product must reserce cell, otherwise when without civil power, protection function will become a kind of illusory, and time without civil power, when may be again exactly the peak that security personnel's accident occurs.So reserce cell is required.And the performance of reserce cell is directly connected to overall performance.

But reserce cell is necessarily to its charge maintenance, to the scientific maintenance of reserce cell, be directly connected to the life-span of reserce cell, with capacity.Have data to think, battery is not usually damaged, but charge improper and damage.Battery in security personnel's equipment, belongs to reserve battery, has particular/special requirement to volume capacity, is equipped with and makes excessive demands in common product.Therefore how to ensure that back-up battery life and unaffected this of capacity are one of problems.

Two of problem is tool repair information statistics, to general charger, and the charging of its inside active of controlling, as switch triode etc. easily damages, it produces fault and accounts for the failure rate ratio of whole equipment very greatly, if therefore this pipe infringement, causes complete machine 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 security personnel's product that this enterprise applies for, the charhing unit of this enterprise can not adopt the common charging method to battery and common charging circuit.

The charging method of its routine adopts single DC charging method, and such method all can make electrolyte continue to produce hydrogen or oxygen gas, and its oxygen, under internal high pressure effect, infiltrates into negative pole and the effect of cadmium plate generates CDO, causes pole plate available capacity to decline.If employing pulse current charge, and employing is filled and puts and the method for depositing, and namely fills certain hour, as 5 seconds, just puts certain hour as 1 second.Major part is reduced into electrolyte by the oxygen that such charging process produces under discharge pulse, gassing rate can be made greatly to reduce, reducing gassing rate can make concentration polarization and ohmic polarization naturally be eliminated, thus alleviate the interior pressure of lead acid accumulator, the pulse current charge of next stage is more successfully carried out, thus makes lead acid accumulator can absorb more electricity.Intermittent pulse makes lead acid accumulator have more sufficient chemical time, thus decreases the gassing rate of lead acid accumulator in charging process, and the charging current that improve lead acid accumulator can ability to accept.Pulse charging method charging certain hour, as 5 seconds, stopping certain hour as discharged for 1 second, so circulating.The oxygen that this charging method can make lead acid accumulator produce in charging process and hydrogen are under stopping charging pulse, the oxygen that major part is separated out and hydrogen have been reduced into again electrolyte, this not only reduces lead acid accumulator internal electrical chemical side reactions in charging process---the gassing rate that the electrolysis of water produces, and cause the lead acid accumulator of inefficacy to also have repair to seriously polarizing, after using this charging method to the certain number of times of lead acid accumulator discharge and recharge lost efficacy, the capacity recovery gradually of lead acid accumulator can be made.Not only according to data introduction by but also the charging method of the two electric discharge of charging, or charging stops the way of filling, not only helpful to lead accumulator, and also helps positively some alkaline cells.

But by above-mentioned charging method, also there are technological difficulties in conventional circuit, because the circuit of routine is not the circuit filling not only but also put, thus with which type of circuit could fill not only but also put, the charging interval could be allowed to become optimum state with the ratio of discharge time, if therefore by traditional design, must complex circuit, newly increase fault point, how to have solved 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, except security personnel's equipment that this enterprise is studied, also have a lot of product, as digital machine machine, mobile phone, etc., the requirement of its charger, also the place of similar enterprise requirements is had, so the research to charger, not only involve the quality of charger itself, also involve by the problem of rechargable battery two aspects.Because an a little good charging measure has positive meaning.

Further illustrate:

1, operation principle explanation.

After opening power supply, all unit are started working, wherein charhing unit and discharge cell, are greater than the process of electric discharge to being undertaken charging by rechargable battery.Until charging terminates.

In charging process, because impulse generating unit work, constantly inner two pipes of control charhing unit are in and open and off-state, so the whole course of work is the pulse current charge adopted.

Not only in pulse current charge process, the charging physical process of employing is, in charging but also in special form of discharging.Also excision switch can be adopted to be excised by discharge cell, and only adopt the form of pulse current charge, thus add selectivity flexibly.

The charge rule coexisted at charge and discharge is, within a cycle of pulse, when when charhing unit is opened discharge cell close, otherwise when when charhing unit is closed discharge cell open-minded.Due within a cycle of pulse, the time of charging is long, and the time of electric discharge is short, so charging process is in AC charging state.Such charging modes is conducive to the scientific maintenance to battery, also has restitution to a certain degree to the battery damaged simultaneously.

When not contacted by rechargable battery, or after being put in place by rechargable battery charging, because charging output exports high-order, end unit is through comparing amplification, export low level signal, the base stage of clamper interface triode (701 in Fig. 2), makes the base stage of interface triode be low level, thus makes this pipe collector for high-order, thus make the base stage of charging triode (301 in Fig. 2) for high-order, make charging triode be in reverse bias, thus make charging triode be in disconnection shape, stop charging to by rechargable battery.

Meanwhile because end unit is through comparing amplification, export low level signal, the clamper negative-phase input of operational amplifier (611 in Fig. 2), make the output of operational amplifier for high-order, allow the biased of discharge diode (9.1 in Fig. 2) be in reverse bias, stop by the electric discharge of rechargable battery.

After full by the battery charging of charging, charhing unit and discharge cell are closed, and now connected trickle resistance (201.1 in Fig. 2) is to the tiny stream electric current being provided required maintenance by rechargable battery.

2, line feature analysis.

(1), end unit.

This unit is by sampling adjustable resistance (501.4 in Fig. 2), the lower inclined resistance (501.3 in Fig. 2) of sampling, comparing on transport and placing device (501 in Fig. 2), homophase inclined voltage-stabiliser tube (501.2 in Fig. 2) under inclined resistance (501.1 in Fig. 2), homophase, sample 501.7 in adjustable limit value resistance (501.5 in Fig. 2), clamp diode 1(Fig. 2), 501.8 in clamp diode 2(Fig. 2) form.

Voltage-stabiliser tube has partially been connected into, so its comparative voltage is very stable under comparing the in-phase end of transport and placing device (501 in Fig. 2).The sampling adjustable resistance (501.4 in Fig. 2) of end of oppisite phase can adjust sampling voltage neatly, again because connected the adjustable limit value resistance of sampling (501.5 in Fig. 2), so can not produce excessive deviation in debug process.Because comparison amplifier has very high sensitivity.So start and stop successful.

(2), interface unit.

This unit is made up of interface triode (701 in Fig. 2), base resistance (701.2 in Fig. 2), door diode (701.1 in Fig. 2).

Interface triode (701 in Fig. 2) base series has door diode (701.1 in Fig. 2), and Main Function exports as low level once the operational amplifier (111 in Fig. 2) of pulse generator, can reliably make interface transistor base be zero-bit.

Interface triode mainly contains four large functions.

One is the pulse current charge logic producing charhing unit.Its reason is under the excitation of pulse unit, through the transmission of this pipe, makes the base stage of charging triode (301 in Fig. 2) produce the pulse change of height.(when interface transistor collector is low level, charhing unit is forward bias, for the state of energising, when otherwise interface transistor collector is high-order, charhing unit is without biased, for off state) thus make the collector electrode of charging triode produce the change of height shape, make whole charging process become pulse current charge shape.

Two is show luminous tube (in figure 801.1) with charging to show under the cooperation of protective resistance (in figure 801) with process, forms the display of charging process.

Three is as complete charge state of switch pipe.After being raised by rechargable battery voltage, end unit exports low level signal, clamper interface transistor base, causes interface transistor collector voltage for high-order, charging triode is closed.

Four is the expansions achieving voltage and current relationship, because this circuit can be used for higher being charged by the battery of rechargable battery and relatively high power, its charging voltage may be 12 volts as being 24 volts, the voltage that voltage high like this may bear higher than normal integrated circuit, simultaneously when being Large Copacity by rechargable battery, charging transistor base electric current may be very large, so can by expanding after mouth triode, and unfettered.

(3), process display unit.

This unit shows protective resistance (801 in Fig. 2) by display luminous tube (801.1 in Fig. 2) of charging with process and forms.

The principle formed is when interface transistor collector is for time high-order, and the branch road that the charging display luminous tube as load is formed becomes open circuit.Otherwise when interface transistor collector is low level, have filling electric current to flow to interface transistor collector from power supply, charging display luminous tube is bright.

(4), impulse generating unit.

The feature of this unit is not only a clapp oscillator, not only can adjust frequency in the line, and can adjust duty ratio.

Impulse generating unit.In this measure, have 3 effects, one is control charhing unit by interface triode, and the form of charging becomes the form of pulse current charge.Two is by interface triode controlled discharge unit, and in charging overall process, realizes the complex form of charging limit, limit electric discharge.Three is the adjustments realizing duty ratio.Make the overall process of charging, realizing and the recombination process of charge and discharge, remain best situation.

It forms pulse, and the principle of frequency-adjustable is, divided by the output of the operational amplifier (611 in Fig. 2) of pulse generator and the connected homophase of in-phase end and press inclined resistance (611.4 in Fig. 2) and to divide with in-phase end homophase over the ground and depress inclined resistance (611.5 in Fig. 2), become in-phase end comparative voltage, also threshold voltage is become, when the output of operational amplifier is high-order, charged to integrating capacitor (611.2 in Fig. 2) by the series arm of duty ratio adjustable resistance (611.7 in Fig. 2), when being charged to threshold values, output cataclysm is low level, at this moment integrating capacitor is discharged to output by the discharge resistance (611.1 in Fig. 2) in duty ratio unit, when current potential is lower than in-phase end, operational amplifier output terminal becomes a high position, start the charging process of second round.Frequency-adjustable resistance (611.3 in Fig. 2) defines frequency of oscillation coarse adjustment, can adjust frequency.

This Measure Design has duty ratio adjustable line, to realize by the adjustment of the discharge and recharge time of rechargable battery.The meaning of duty ratio be pulse in one-period, the ratio of high bit time and low bit time.

Realize that duty ratio is adjustable to be formed by the duty ratio adjustable resistance (611.7 in Fig. 2) of capacitor charging, steering diode (611.6 in Fig. 2), duty limiting resistance (611.8 in Fig. 2) series arm and discharge resistance (611.1 in Fig. 2).

Form pulse duty factor different and adjustable principle can be realized be: the resistance (611.1) of discharge resistance is very large in this unit, and the resistance carrying out the duty ratio adjustable resistance of charging and duty limiting resistance in series arm is very little, so when the operational amplifier in pulse generator is for exporting as time high-order, to the charging of integrating capacitor, complete (because this branch road series resistance value is little) primarily of series arm, otherwise when capacitor discharge, because steering diode is in reverse bias, so become open circuit, integrating capacitor electric discharge can only be completed by discharge resistance, to form output voltage low time long, and export short situation of high time.

When such situation implements to and charges to battery, within the one-period time of pulse, be that the charging interval is long and the time that is electric discharge is short, and be the situation of charging to what formed by rechargable battery on the whole.

Because the charging paths in this unit is two resistant series, and one of them resistance is adjustable, series connection total resistance value is little then fast to integrating capacitor charging, so the time of an output high position for the large device of computing is shorter, otherwise longer, thus achieve duty ratio adjustable resistance.What connect with adjustable resistance is in duty ratio adjustable resistance process because determining resistance meaning, even if adjustable resistance is zero, the resistance value being unlikely to this branch road is zero.

Because generating unit has frequency-adjustable resistance and duty ratio adjustable resistance, so relative maximum scientific to being realized by the charging of rechargable battery.

(5), charhing unit is made up of the triode that charges (301 in Fig. 2) and biasing resistor (301.1 in Fig. 2): when in the one-period of pulse, the collector electrode of interface triode (701 in Fig. 2) has height two states, therefore control charging triode and form Push And Release two states, form the charged form of pulse.

(6), discharge cell is become to form by discharge diode (9.1 in Fig. 2), electric discharge base resistance (9.2 in Fig. 2), electric discharge excision switch (9.5 in Fig. 2), discharge resistance group (9.6 in Fig. 2).

Electric discharge base resistance is by the control of operational amplifier (611 in Fig. 2), when the output of operational amplifier is high-order, now charhing unit is open-minded, charges to by rechargable battery, and discharge diode (9.1 in Fig. 2) is because be reverse bias, therefore be off state, when the output of operational amplifier is low level, now charhing unit is closed, and discharge diode is forward bias, therefore be opening state, discharge to by rechargable battery.

Discharge resistance because bear discharging current, therefore its power >=3W.

The base stage of discharge diode is connected with excision switch (9.5 in Fig. 2) over the ground, when excising switch connection, only formed to by the charging of rechargable battery with stop the state of filling, add flexibility.

(7), operational amplifier is use integrated circuit 4558 with comparing transport and placing device, its withstand voltage higher, therefore more not fragile than LM324.

This measure has outstanding advantage after implementing:

1, be the life-span substantially increasing charger by this measure one, decrease the scrappage of charger, two is to being achieved science charging by rechargable battery, enhancing maintenance, extend by the life-span of rechargable battery, decrease scrappage.And these two kinds of products, no matter be chargeable battery, or supporting charger, be all the kind that the modern life is generally applied, so the environmental protection of two kinds of products can be strengthened.Environmental protection is without minor matter, so this measure has positive effect.

2, this measure also has important economic worth, for the value of common electronic product, as this series products of charger, do not having under valuable first material, its main points: first is Value of Science & Technology, second is manually add expense, 3rd cost being only element, and the element that this measure increases is limited.After this measure is implemented: one by rechargable battery life, and two is that capacity significant change can not occur, therefore society is bound to accept, and admit its scientific value, therefore this excellent product can replace the product of inferior quality.Due in the modern life, this product purpose is very general, so can produce significant economic worth.

3, the charged form filling not only but also put is adopted, there is significant maintenance effects to by rechargable battery, some critics claim that chargeable battery is filled on the net bad, instead of damage, and this measure can be closed by the relative maximum scientific maintenance of the charging of rechargable battery, particularly 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 recovery to a certain extent, so meaning is very large.

4, this measure excellent performance, one is to adjustable flexibly by the ratio between the charging and discharging time of rechargable battery, namely be that duty ratio is adjustable, two is frequency-adjustable of paired pulses, three is to adjustable flexibly by charging voltage complete charge value, so from multi-angle stage construction, adapted to variety classes model by rechargable battery model.Another important point can charge to jumbo battery, as long as now the triode of charhing unit and discharge cell is changed to large power triode.In addition this measure is not afraid of in addition and is overcharged etc. advantage.

5, be connected between each unit of this measure science, and accomplished comprehensive utilization, and thus line circuit is simplified, reliability is high.

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