Belong to electronic technology 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 live part 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 not only charging but also the charging method of electric discharge, 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, the control valve how controlling Push And Release could be formed and fill and coexisting of putting, which type of circuit reliably could adjust the time of charging and the time of electric discharge with again, reach the allocation proportion of effective the best of charging interval and 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, and wherein innovate controllable silicon charhing unit and have been carried out charging work until terminate with innovation controllable silicon discharge cell to by rechargable battery.The feature one of charging is charging in a pulsed fashion, and two is in the one-period of pulse, oriented by the charging process of rechargable battery, also oriented process of being discharged by rechargable battery, but the time of charging is greater than the charging process of electric discharge.So overall physical process is charging.Three is that charge circuit is through the charging of innovation controllable silicon charhing unit.Discharge loop is by the electric discharge of innovation controllable silicon discharge cell.

In charging process, because during the work of ring oscillation formula impulse generating unit, ring oscillation formula impulse generating unit controls SCR control unit by charge display, constantly make two controllable silicons in innovation controllable silicon charhing unit be in open and off-state, so charge circuit generation is pulse current.

In the cycle in pulse current charge process, not only the effect of generation is in charging but also in special form of discharging.But the present invention also devises excision switch (9.11 in Fig. 2), allow innovation controllable silicon discharge cell without biased ,make this part be in excision state, and only adopt the form of pulse current charge, thus add selectivity flexibly.

The charge rule that charge and discharge coexists is, within a cycle of pulse, when when innovation controllable silicon charhing unit is opened, innovation controllable silicon discharge cell is closed, otherwise open-minded when innovating controllable silicon discharge cell when innovating controllable silicon charhing unit and closing.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 pulse current charge state.Such charging modes is conducive to the scientific maintenance to battery, simultaneously to the restitution also had by rechargable battery to a certain degree of partial destruction.

When not contacted by rechargable battery, battery terminal contact instruction lamp (16.3 in Fig. 2) in battery terminal contact display branch road has not worked, because the electric current of this part instruction is not when plugging alternating current, only derives from battery.Now, instruction user should be clipped by rechargable battery.

When not put in place by rechargable battery voltage, because innovation controllable silicon charhing unit conducting charging, after being put in place by rechargable battery charging, because charging output exports high-order, because threshold values adjustable elements output voltage has arrived the input threshold values of end unit, preposition shaping amplifier (14.1 in Fig. 2) exports anti-phase, second shaping amplifier (14.2 in Fig. 2) still keeps high-order, now terminate controllable silicon (14.3 in Fig. 2) to be triggered, thus clamper charging silicon controlled controls pole, makes the open circuit of innovation controllable silicon charhing unit.Finishing control diode (14.5 in Fig. 2) excitation charge display (8.0 in Fig. 2), charge display is made to export as low level, thus the control pole of clamper discharging thyristor, close innovation controllable silicon discharge cell, innovation controllable silicon discharge cell also quits work and becomes open-circuit condition, and thus whole circuit is closed.

Now connected trickle resistance (2.1 in Fig. 2) is to the tiny stream electric current being provided required maintenance by rechargable battery.

2, line feature analysis.

(1), the explanation of threshold values adjustable elements and end unit.

Wherein: threshold values adjustable elements is by starting inclined protective resistance (13.1 in Fig. 2) in adjustable inclined resistance (13.2 in Fig. 2), starting, starting and descend inclined resistance to form (13.3 in Fig. 2); End unit is by preposition shaping amplifier (14.1 in Fig. 2), the second shaping amplifier (14.3 in Fig. 2), feedback circuit, end controllable silicon (14.3 in Fig. 2), and finishing control diode (14.5 in Fig. 2) forms.

Feedback circuit is made up of Derivative Feedback electric capacity (14.6 in Fig. 2), feedback diode (14.7 in Fig. 2), discharge resistance (14.8 in Fig. 2).

Select two key benefit making preposition shaping amplifier and the second shaping amplifier respectively to have two in this unit, one is be a kind of model with the door of ring oscillation formula impulse generating unit, is convenient to produce.Two is threshold values that door has upset, once exceed threshold values, door just overturns, and three is after two series connection, has and amplifies shaping operation further, further shorten the switching process of door.Thus good performance is had.Start adjustable inclined resistance (13.2 in Fig. 2) and sampling voltage can be adjusted neatly, start upper inclined protective resistance (13.1 in Fig. 2), so excessive deviation can not be produced in debug process because connected again.Due to such circuit, threshold values is obvious, has again two amplifications of connecting, so there is very high sensitivity.And the effect of feedback circuit has just arrived threshold values when threshold values adjustable elements, accelerate the startup of end unit, thus proceed-to-send effect is more obvious.

When end unit has high-order output, a high position has been passed to the input of vibration three by finishing control diode (14.5 in Fig. 2), thus vibration is allowed to stop, high position transmission is also given charge display (8.0 in Fig. 2) by finishing control diode simultaneously, so make innovation controllable silicon discharge cell without pumping signal, the work of discharge portion stops.Terminate controllable silicon (14.3 in Fig. 2) clamper charging control point, make inner two silicon controlleds of live part control very low level, become cut-off, stop charging.Now, charge and discharge all quits work, and only has trickle resistance (2.1 in Fig. 2) to the tiny stream electric current being provided required maintenance by rechargable battery.

(2), SCR control unit.

This unit is made up of Pulse Width Control controllable silicon (6.1 in Fig. 2) and Pulse Width Control controllable silicon negative electrode diode (6.2 in Fig. 2).

The control pole of Pulse Width Control controllable silicon (6.1 in Fig. 2) is subject to the control of charge display (8.0 in Fig. 2), and Pulse Width Control silicon controlled anode direct clamper charging silicon controlled controls pole.

Thus Pulse Width Control controllable silicon mainly contains two large functions,

One is the AC charging logic producing innovation controllable silicon charhing unit.Its reason is under the excitation of ring oscillation formula pulse unit, this Pulse Width Control controllable silicon is controlled through charge display (8.0 in Fig. 2), make Pulse Width Control silicon controlled anode produce high and low pulse change, thus make two silicon controlleds in innovation controllable silicon charhing unit control the pulse change that pole produces height.When Pulse Width Control silicon controlled anode is high-order, in charhing unit, two silicon controlleds control poles are encouraged, for saturated opening state, otherwise Pulse Width Control controllable silicon current collection very low level time, in charhing unit, two silicon controlleds control pole by clamper, in charhing unit, two controllable silicons are cut-off off state, thus make the output of innovation controllable silicon charhing unit produce the change of height shape.Whole charging process is made to become pulse current charge shape.

Two is the expansions realizing 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, the silicon controlled of live part controls electrode current may be very large, so can by expanding after Pulse Width Control controllable silicon, and unfettered.

(3), charging display unit.

This unit is made up of charge display (8.0 in Fig. 2), charging display branch road.

Charging display route charging display protective resistance (8.1 in Fig. 2) is in series with charging indicator light (8.2 in Fig. 2).

When ring oscillation formula impulse generating unit works, charging display controller height Changing Pattern is identical with the rule of ring oscillation formula impulse generating unit, thus the display of excitation charging indicator light, when charging terminates, end unit exports high-order, causes charging display controller to export as low level.Charging indicator light is excited target not, thus not luminous.

(4), impulse generating unit.

Ring oscillation formula impulse generating unit is made up of three vibration doors, oscillating capacitance, charge and discharge branch road, charging paths, ring resistances.

Charge and discharge is propped up route frequency adjustable resistance (7.4 in Fig. 2) and is in series with frequency limitation resistance (7.5 in Fig. 2), and charging paths is in series than limiting resistance (7.8 in Fig. 2), duty ratio adjustable resistance (7.7 in Fig. 2) by steering diode (7.6 in Fig. 2), some sky.

The feature of this unit is a clapp oscillator, has frequency adjustment, adjust with duty ratio in this circuit.

Impulse generating unit.Have 3 effects in the present invention, one is by Pulse Width Control SCR control innovation controllable silicon charhing unit, makes the form of charging become the form of pulse current charge.Two is control innovation controllable silicon discharge cell by charge display, makes in charging overall process, realizes charging limit, limit electric discharge complex form.Three is the adjustments realizing duty ratio.Make the overall process of charging, realizing and the recombination process of charge and discharge, remain best allocation proportion.

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

Its reason constitutes a ring oscillator by vibration one (7.1 in Fig. 2), vibration two (7.2 in Fig. 2), vibration three (7.3 in Fig. 2) with above-mentioned circuit, and the charging paths resistance that charge and discharge branch road ratio wherein has steering diode (7.6 in Fig. 2) to form is much bigger, so the frequency of ring oscillator is fixed primarily of charge and discharge branch road, adjust the adjustment of the resistance of this branch road, just the frequency of this oscillator can roughly be determined, (because frequency is also decided by that duty ratio is namely relevant with charging paths accurately).The minimum resistance of the frequency limitation impedance versus frequency adjustable resistance of charge and discharge branch road plays limit value effect.

The oscillation principle that ring oscillator is formed is, when the output of vibration one (7.1 in Fig. 2) is high-order, the output of two (7.2 in Fig. 2) of vibrating is low level, if there is no oscillating capacitance (7.9 in Fig. 2) for open circuit, then because of the existence of charge and discharge branch road, the input of vibrate three (7.3 in Fig. 2) should be low.But because there is the existence of oscillating capacitance, can not transition, directly a high position is passed to the input of vibration three, so the input of vibration three is in the charging process of electric capacity, become a high position.At this moment the output of vibration three is low, the output of vibration one is caused to continue as height, this state continuance terminates to oscillating capacitance charging, be split into the front half period of vibration, after first half end cycle, three gate output terminal fusions of vibrating are low, cause vibration two gate output terminal for high-order, therefore form the reciprocal electric discharge of oscillating capacitance, form the later half cycle of vibration.

B, this Unit Design have duty ratio adjustable.

The meaning of duty ratio be pulse in one-period, the ratio of high bit time and low bit time.

Duty ratio adjustable line forms jointly primarily of oscillating capacitance and charging paths.

Forming adjustable principle is: when vibration one (7.1 in Fig. 2) output is for time high-order, this high-order output end current is through the parallel branch of oscillating capacitance charge and discharge branch road and charging paths, then the low level output of flow direction oscillation two (7.2 in Fig. 2), what the resistance due to charging paths series connection was larger is less than charge and discharge branch road, so there is the charging current of charging paths to be leading composition.Regulate the adjustable of this branch road, duty ratio can be regulated further.Duty-cycle limit resistance (7.8 in Fig. 2) in this is the restriction to duty ratio adjustable resistance (7.7 in Fig. 2) minimum value.After oscillating capacitance (7.9 in Fig. 2) charging terminates, when the output of two of vibrating is high-order, the high-order output of two of vibrating does reciprocal electric discharge by the parallel branch of charge and discharge branch road and charging paths to oscillating capacitance, because charging paths in two branch roads has the existence of steering diode (7.6 in Fig. 2), its reverse bias is infinitely great, so the main branch road of electric discharge is charge and discharge branch road.It should be noted that, because the output of this unit is after Pulse Width Control controllable silicon (6.1 in Fig. 2) is anti-phase, control charging controllable silicon (3.1 in Fig. 2), the time of oscillating capacitance charging is shorter, it is longer then to innovate the time that controllable silicon charhing unit opens, so the duty ratio of this unit is adjustable be built up in charging paths, and be not built up in a major reason of charge-discharge circuit.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 what formed supplementary battery on the whole is the situation of charging.

Due to impulse generating unit, there is frequency-adjustable and duty ratio is adjustable, so relative maximum scientific to being realized by the charging of rechargable battery.

C, impulse generating unit are to the logical relation of live part and discharge portion.

The input of charge display is equal to the output being connected to vibration two (7.2 in Fig. 2), the output of charge display (8.0 in Fig. 2) is made to produce the different conversion of height along with vibration, when the output of charge display is high-order, the anode of Pulse Width Control controllable silicon (6.1 in Fig. 2) is low level, thus the controllable silicon in clamper innovation controllable silicon charhing unit, so innovation controllable silicon charhing unit is open circuit, controllable silicon in innovation controllable silicon discharge cell now, because the now output of charge display is high-order, so the controllable silicon in stimulating innovation controllable silicon discharge cell is saturatedly to discharge to by rechargable battery.

Otherwise, when impulse generating unit upset, when making the output of charge display be low level, Pulse Width Control controllable silicon anode is high-order output, and the controlled electrode resistance of controllable silicon in innovation controllable silicon charhing unit triggers, the conducting of innovation controllable silicon charhing unit, charging, the now output of charge display is low level, and the controllable silicon in innovation controllable silicon discharge cell is without exciting current, and the controllable silicon in innovation controllable silicon discharge cell becomes the off state of cut-off state.

(5), charging silicon controlled feature and explanation.

The internal structure of one-way SCR as shown in Figure 3, its inside is equivalent to the combination of a NPN triode and a PNP triode, its principle triggered is, when the NPN transistor base of inside has the forward bias of triggering, its collector electrode produces amplified current, this electric current is again the base current of PNP triode, and the collector current that this pipe amplifies becomes the base current of PNP triode, has thus been split into strong positive feedback.

The controllable silicon of innovation have been connected diode at its negative electrode, thus improve the forward bias voltage of NPN triode, last diode cathode of connecting becomes the false negative electrode of innovation silicon controlled, therefore when base stage and the false negative electrode short circuit of NPN triode, because forward bias increases, then the base current Rong Yang direct short-circuit of NPN pipe is to ground, and need not produce transistor effect by inner PN joint.So such benefit is, to saturated controllable silicon, as long as will the current potential of pole negative electrode be controlled lower than false negative electrode, just can realize the cut-off of saturated controllable silicon, and the way of the minimizing anode current introduced in teaching need not be adopted.

That is to say that namely controllable silicon has controllable silicon and easily trigger saturated character, has again and controls pole and reach the character allowing it end with after innovation controllable silicon.This character also obtains testing sufficient confirmation.

In innovation controllable silicon charhing unit, controlling electrode resistance is trigger action, and composition charging innovation silicon controlled negative electrode series diode (3.9 in Fig. 2), its effect is that the controllable silicon in live part can reliably be ended.

(6) discharging thyristor, in innovation controllable silicon discharge cell is also connected to composition electric discharge innovation silicon controlled negative electrode series diode, the same with the charge use of silicon controlled negative electrode series diode of composition, is also that to allow discharging thyristor end easy.

The control pole of discharging thyristor is connected with excision switch (9.11 in Fig. 2) over the ground, can connect excision switch, allow discharging thyristor end, and now only has charging and stops the state of filling, and the existence of discharge off, add flexibility.

Outstanding advantage is had after the invention process:

1, be the life-span substantially increasing charger by the present invention 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 the present invention has positive effect.

2, important economic worth is also had, for the value of common electronic product, as this series products of charger, do not having under famous and precious first material, so first is Value of Science & Technology, second is manually add expense, 3rd cost being only element, and the element that the present invention increases is limited.After this measure is implemented, one by rechargable battery life, and two is that capacity significant change can not occur, and 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, excellent performance of the present invention, 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.In addition the present invention is not afraid of in addition and overcharges etc. advantage.

5 to be connected with each unit science, and have 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.
