Background technology

This enterprise has applied for security personnel's product line for the previous period, and this product has to reserce cell, otherwise when no city When electric, protection function will become a kind of illusory, and no civil power when, when being exactly probably the peak that security personnel's accident occurs again Wait.So reserce cell is necessary.And the performance of reserce cell is directly connected to overall performance.

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.There is the data to think, battery is often not to be damaged, but charge improper and damage.In security personnel's equipment Battery, belong to reserve battery, have particular/special requirement to volume capacity, be equipped with and make excessive demands in common product.Therefore how to ensure backup Battery life and unaffected this of capacity are problems.

Because above-mentioned reason, for ensureing the performance of this enterprise apllied security personnel product, the live part of this enterprise can not Using the common charging method to battery and common charging circuit.

Its conventional charging method is using single DC charging method, and such method all can make electrolyte persistently produce hydrogen Carrier of oxygen, under the high pressure effect internally of its oxygen, infiltrates into negative pole and generates CDO with the effect of cadmium plate, cause under pole plate available capacity Fall.If adopting pulse charge, and using the method using filling Yu stop and deposit, that is, filling certain time, such as 5 seconds, just stopping 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 substantially reduces, and reducing gassing rate can make concentration polarization and ohmic polarization naturally be eliminated, thus alleviating Lead-acid accumulator intrinsic pressure, so that the pulse charge of next stage is more successfully carried out, so that lead-acid accumulator can absorb More electricity.Intermittent pulse makes lead-acid accumulator have more sufficient chemical time, thus decreasing lead in charging process The gassing rate of acid accumulator, the charging current that improve lead-acid accumulator is subjected to ability.Pulse charging method charges certain time As 5 seconds, put or stop certain time such as 1 second, so circulate.This charging method can make lead-acid accumulator in charging process , under stopping charging pulse, most of oxygen separating out and hydrogen have been reduced into electrolyte again for produced oxygen and hydrogen, This not only reduces the gassing rate produced by electrolysis of lead-acid accumulator internal electrochemistry side reaction water in charging process, And to seriously polarization and cause the lead-acid accumulator of inefficacy to also have repair, using this charging method to lost efficacy After the certain number of times of lead-acid accumulator discharge and recharge, the capacity of lead-acid accumulator can be made gradually to recover.Not only according to data introduction by but also fill Electricity stops the charging method filled again, not only helpful to lead battery, and some alkaline cells are also helped positively.

But by above-mentioned charging method, conventional circuit is also to there are technological difficulties, because the circuit of routine is not The circuit filling not only but also stopping, if by traditional design, must complex circuit, newly increased trouble point, how to have solved these lances Shield, becomes new difficult point.

Abundant with the modern life, got more and more with the species of the electrical equipment of battery, the security personnel being studied except this enterprise Outside equipment, also a lot of products, such as digital machine machine, mobile phone, etc., the requirement of its charger, also there are 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 one good charging measures have positive meaning.

First, operation principle explanation.

After energising, impulse hunting unit starting of oscillation, form impulse scaler output height and convert, continuous control interface audion （In Fig. 2 3.1）, so that charhing unit and discharge cell is in and open and close, allow charhing unit and discharge cell jointly to quilt The charging work that rechargable battery is charged not only but also discharges, and whole work process is the pulse current charge adopting.

During pulse charge, the charging physical process of employing is to there is charging not only but also there is the spy of electric discharge Different form.The logic that charge and discharge coexists is, when charhing unit open to be electrically charged pond and charge when, discharge cell is closed；Single when charging When unit closes, discharge cell is opened to being electrically charged tank discharge.Because, in a cycle of pulse, the time of charging is long, and puts The time of electricity is short, so present is the state charging；Such charging modes are conducive to the scientific maintenance to battery, simultaneously right The battery of damage also has a certain degree of restitution.

The charge rule being formed is, within a cycle of pulse, when the current collection extremely low level of interface audion, charges Unit close, stop charge, the discharge tube base stage in discharge cell now through interface audion colelctor electrode to ground wire, shape Become bias current passage, discharge cell is open-minded, to being electrically charged pond spark.When the current collection of interface audion is extremely high-order, charge Charging instrumentation tubes in unit are triggered, and charge to being electrically charged pond, and the bias current passage of discharge cell disappears, discharge cell closes Close.

It should be noted that only in pipe charhing unit charging operating circuit and charging await your instructions circuit to be electrically charged pond constitute or Door power supply mode, but the particularity by design measure, usually only charging work power on circuitry work, and the circuit of awaiting your instructions that charges It is in open-circuit condition, but once charging operating circuit damages, the circuit of awaiting your instructions of charging will automatically engage energising work.

In the same manner it should however be pointed out only in tube discharge unit electric discharge operating circuit and electric discharge await your instructions circuit to being electrically charged pond composition OR gate forms discharge mode to being electrically charged pond, but particularity by design measure, usually only electric discharge operating circuit energising Work, and the circuit of awaiting your instructions of discharging is in open-circuit condition, but once electric discharge operating circuit damages, electric discharge circuit of awaiting your instructions will be thrown automatically Enter the work that is energized.

When being electrically charged pond and being not in contact with, it is electrically charged pond contact display lamp and does not work.

This practical end has two kinds of Starting mode, is selected by terminating select unit, and a kind of is start by set date, pin For the battery that some are charged for the first time, need not separately set the time again.The mode that terminates of timing is：When regularly when time is up, regularly Device（In Fig. 2 7.0）Timing at the end of output high signal from the high-tension ultimate outfan of low-voltage output, one is tactile Send out impulse scaler（In Fig. 2 6.1）Clear terminal, two be triggering finishing control audion, make finishing control audion（Fig. 2 In 9.1）Current collection extremely low level, clamper interface audion while clamper charhing unit（In Fig. 2 3.1）, charge closing Unit and discharge cell, now charging process display lamp（In Fig. 2 2.2）Put out.Another kind starts for pressure limiting, is when battery is full of After electricity, after the side pressure of battery exceedes the threshold value that pressure limiting threshold cell is formed, pressure limiting threshold cell exports high pressure, starts end and holds Row unit, charge closing unit and discharge cell, and the clear terminal of trigger pulse enumerator, make impulse scaler failure of oscillation.Now Connected trickle resistance（In Fig. 2 30）There is provided the tiny stream electric current of required maintenance to being electrically charged pond.

2nd, line feature analysis.

1st, interface unit.

This unit is by interface audion（In Fig. 2 3.1）, interface triggering resistance（In Fig. 2 3.2）, charge control two pole Pipe（In Fig. 2 3.3）Composition.Interface audion mainly produces following functions：

One is that the direct current of charging is become pulse charge stream.Its reason is in impulse scaler（In Fig. 2 6.1）Swash Encourage down, through the transmission of this audion, make the base stage of charhing unit produce the pulse change of height.（Interface transistor collector During for a high position, charhing unit is forward bias, for the state of energising, otherwise when interface transistor collector is low level, charges single Unit is no to bias, and is off state）So that the outfan of this unit produces the change of height shape.Thus charging current is pulse Electric current, makes charhing unit produce and charges and stop filling two states.

Two is to provide bias current passage for discharge cell.Produce in a cycle of pulse, have the function of electric discharge.When this pipe is During low level, in discharge cell, the base current of two audions enters ground by the colelctor electrode of interface audion, thus makes discharge cell Interior audion is opened and is become discharge condition.

3rd, charhing unit and discharge cell is made to produce correct logic.The requirement of the present invention is, in a cycle of pulse Interior, when charhing unit is in and opens charged state, discharge cell is in closing off state.Otherwise when charhing unit be in disconnected During the closed mode of road, discharge cell should be at opening discharge condition.And interface transistor collector is when being high-order, charhing unit Audion is in be penetrated with state, charges.And discharge cell two audion unbiased is put, it is closed.Otherwise interface audion Current collection extremely low level when, penetrating of charhing unit is shorted with base flow, for close shape, and discharge cell two audion base flows pass through Interface audion enters ground, so conducting.

Four is the control pipe becoming discharge cell termination.After battery is fully charged, the side pressure of battery exceedes pressure limiting threshold value list After the threshold value that unit is formed, pressure limiting threshold cell starts, thus trigger pulse enumerator（In Fig. 2 6.1）Clear terminal, make arteries and veins Rush counter O reset, no longer have output, make interface audion（In Fig. 2 3.1）Logic will produce current collection extremely high signal, Thus discharge cell is off state.

Five is excitation charging process display lamp（In Fig. 2 2.2）Flash of light.When this pipe collector is low level, electric current is from electricity , to interface transistor collector, charging process display luminous tube is bright for source stream.Otherwise do not work.Interface audion current collection at the end of charging Extremely high-order, charging process display luminous tube does not light.

2nd, to the explanation terminating two kinds of Starting mode.

This practical Starting mode implementing two kinds of end, by selecting switch（In Fig. 2 11.1）Switch over, a kind of Start for pressure limiting, a kind of is start by set date, triggers end performance element in the way of OR gate, thus close charged in parallel unit with Discharge cell, stops charging, and allows impulse scaler to reset.

The pressure limiting start end of pressure limiting threshold cell respectively connects an end choosing with the power control terminal of the intervalometer of timing unit Select one end of diode, the end connecing pressure limiting start end selects the other end of diode to be respectively connected to the normally closed tactile of selecting switch Point, the end connecing the power control terminal of intervalometer selects another termination normally opened contact of diode, and the conversion of selecting switch is touched Point earth lead, thus when the normally-closed contact of selecting switch is communicated with transfer contact, pressure limiting start end is equal to and has connect ground wire, now Terminate to start for timing, when the normally opened contact of selecting switch is communicated with transfer contact, the power control terminal of intervalometer is equal to and connects Enter ground wire, now start for pressure limiting.It is consequently formed the conversion of two kinds of end Starting mode.

（1）, the explanation of timing unit.

Timing unit is by intervalometer（In Fig. 2 7.0）, timing oscillation resistance（In Fig. 2 7.9）, timing oscillating capacitance（Figure In 2 7.10）, the clearing electric capacity of intervalometer（In Fig. 2 7.15）, differential audion（In Fig. 2 7.17）, earth resistance（Fig. 2 In 7.16）, ground capacity（In Fig. 2 7.11）, the protective resistance of intervalometer（In Fig. 2 7.12）, intervalometer power supply steady Pressure branch road（In Fig. 2 7.13）, the power supply steering diode of intervalometer（In Fig. 2 7.20）, timing failure of oscillation diode（In Fig. 2 7.19）, regularly terminate start diode（In Fig. 2 7.18）Composition.

Intervalometer has 8 feet, the power input of intervalometer（In Fig. 2 7.8）, i.e. the 8th foot；The ground terminal of intervalometer （In Fig. 2 7.4）, i.e. the 4th foot；The Non-follow control input of one intervalometer（In Fig. 2 7.1）, i.e. the 1st foot；One timing The reset terminal of device（In Fig. 2 7.7）, i.e. the 7th foot；The oscillation inputs of one intervalometer（In Fig. 2 7.6）, i.e. the 6th foot；One The oscillation output end of individual intervalometer（In Fig. 2 7.5）, i.e. the 5th foot；Two ultimate outfans（In Fig. 2 7.2,7.3）；Wherein For exporting low-voltage, i.e. the 2nd foot from high voltage at the end of timing, another ultimate outfan is timing knot to one ultimate outfan Shu Shicong low-voltage output high voltage, i.e. the 3rd foot.

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

Structure within intervalometer is that the 5th foot of intervalometer is oscillation output end, that is to say the outfan of interior door 1, fixed When device the 6th foot be interior door 2 input, when the input of door 2 is low level, the outfan of door 1 is a high position.Conversely, working as door 2 Input be a high position, the outfan of door 1 is low level.So the principle forming vibration is, after energising, because timing oscillating capacitance Uncharged, so oscillation output end output is high-order, 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 is become for low level by high-order again, so timing is shaken Swing electric capacity to discharge further through timing oscillation resistance, form the later half cycle of vibration.

According to the oscillation principle of this intervalometer vibration, so this measure is that timing oscillation resistance is become fixing and adjustable two The cascade of resistance, to realize the adjustable of frequency, ensure simultaneously frequency adjustable in certain limit, so increased fixing electricity Resistance limits as the minima of adjustable resistance.

Its adjustment law is that timing oscillation resistance is bigger, and the cycle is longer, and timing is longer, otherwise shorter.Increased frequency is Cycle, adjustable benefit was, was adapted to multiple needs being electrically charged pond.

Terminated clear circuit in the reset of intervalometer, by the clearing electric capacity of intervalometer, differential audion, earth resistance with Ground capacity forms, and its benefit is each energising, all intervalometer is once reset it is ensured that each timing accurate Property.

Because the 3rd foot of intervalometer is the ultimate outfan being changed into high level at the end of timing from low level（In Fig. 2 7.3）, so ought regularly terminate, the 3rd foot output is high-order, starts and terminates performance element, makes finishing control audion（In Fig. 2 9.1）Conducting, its current collection extremely low level, charhing unit clamper, charge closing unit make interface audion end simultaneously, close Discharge cell.3rd the high-order of foot output enters impulse scaler simultaneously（In Fig. 2 6.1）Clear terminal, pulse count device is clear Zero, make impulse scaler stop counting.

Charging process display lamp（In Fig. 2 2.2）Put out, now stop charging, by trickle resistance（In Fig. 2 30）To electric Pond provides and maintains trickle.

（2）, pressure limiting start explanation.

Pressure limiting threshold cell is by adjustment resistance inclined in pressure limiting（In Fig. 2 8.1）, limiting resistance partially in pressure limiting（In Fig. 2 8.2）, resistance partially under pressure limiting（In Fig. 2 8.3）, pressure limiting terminate start diode（In Fig. 2 8.5）, pressure limiting failure of oscillation diode （In Fig. 2 8.7）Composition.

In pressure limiting partially adjustment resistance, limiting resistance and resistance inclined under pressure limiting partially together form pressure limiting threshold value in pressure limiting, when Battery is fully charged, and the side pressure of battery exceedes this threshold value, and pressure limiting start end will export high pressure, starts and terminates performance element, makes Finishing control audion（In Fig. 2 9.1）Conducting, its current collection extremely low level, charge closing unit and discharge cell, simultaneously the 3rd The high-order of foot output enters impulse scaler（In Fig. 2 6.1）Clear terminal, pulse count device reset, make impulse scaler Stop counting.

In pressure limiting, adjustment resistance can reliably adjust the threshold value of pressure limiting partially, and in pressure limiting, inclined limiting resistance is partially to adjust in pressure limiting The restriction of whole resistance minima.

3rd, impulse scaler, pulse reset unit and impulse hunting unit.

(1), its Main Function be the feature of impulse scaler and impulse hunting unit be to be not only a clapp oscillator, Frequency not only can be adjusted in circuit, and dutycycle can be adjusted.

Impulse scaler and impulse hunting unit have 3 points of effects in the present invention, and one is by interface audion（In Fig. 2 3.1）Control charhing unit, and make the form of DC charging become the form of pulse charge.Two is by interface audion Control discharge cell, and make in charging overall process, complex form of realizing discharging in charging.Three is by interface audion control System charges and shows luminous tube（In Fig. 2 2.2）, form charging process instruction.Four is the regulation realizing dutycycle.Make the complete of charging Process, is realizing charging again and is stopping the recombination process filling, remain optimal ratio state.

(2), principle composition and feature.

Impulse hunting unit is made up of oscillating circuit, frequency regulating circuit, duty cycle circuit.

Vibration within impulse scaler for the oscillating circuit one（In Fig. 2 6.11）, the vibration within impulse scaler Two（In Fig. 2 6.12）, with counting oscillating capacitance（In Fig. 2 6.13）, count oscillating capacitance series resistance（In Fig. 2 6.18）Composition, frequency regulating circuit is by frequency limit resistance（In Fig. 2 6.14）Series connection frequency-adjustable resistance（In Fig. 2 6.15）Composition, duty cycle circuit is by steering diode（In Fig. 2 6.16）Series connection duty ratio resistance（In Fig. 2 6.17）Composition. Wherein within impulse scaler two wherein first are the vibrations one within impulse scaler（In Fig. 2 6.11）, Two is vibration two within impulse scaler（In Fig. 2 6.12）.

Wherein by frequency limit resistance（In Fig. 2 6.14）Series connection frequency-adjustable resistance（In Fig. 2 6.15）Constitute frequency Rate adjustment circuit simultaneously can achieve frequency-adjustable.Oscillating circuit forms the principle vibrating, the vibration two within when impulse scaler When door is output as a high position, by counting oscillating capacitance, discharge and recharge branch road, and vibration one within to impulse scaler for the discharge paths The outfan of door, is split into the charged state counting oscillating capacitance, the central point now connecting, and is to count oscillating capacitance and meter The junction point of number oscillating capacitance series resistance, for a high position.The input leading to the vibration one within impulse scaler is a high position, Until the end of vibration first half cycle.After the threshold voltage that the isolation effect counting oscillating capacitance makes center point voltage be less than door （I.e. after threshold voltage）, the outfan of the vibration one within impulse scaler is changed into high from low filling, at this moment in impulse scaler The outfan output current of the vibration in portion one passes through discharge and recharge branch road with the parallel circuit of discharge paths to counting oscillating capacitance Carry out reciprocal discharge process.It is now the later half cycle of vibration, until the end in later half cycle, when the magnitude of voltage of central point After threshold value, repeat the process of a cycle again.Carry out later vibration.

The present invention is that vibration is reliable using the reason this oscillating circuit one, and used by two, element is few, and three is to set up frequency Rate is adjustable, holds than adjustable with accounting for.

(3), the composition of frequency regulating circuit and principle.

In this unit, frequency-adjustable resistance has been composed in series frequency regulating circuit with frequency limit resistance, this circuit It is also a discharge and recharge branch road.

Vibration two gate output terminal within when impulse scaler is a high position, and one output of the vibration within impulse scaler When holding as low level, the electric current of the vibration two gate output terminal output within impulse scaler is through counting oscillating capacitance and frequency adjustment electricity Road and duty cycle circuit and flow into vibration one gate output terminal impulse scaler within, in this charging process, frequency adjustment Two resistance values of circuit are far longer than the resistance of duty cycle circuit, but duty circuit has steering diode, are now in anti- To biasing, so now charging current is passed through from frequency regulating circuit completely, so this circuit can carry out coarse adjustment to frequency.Its Rule is that the adjustable resistance of this circuit is less, then the charging counting oscillating capacitance can more early put in place, thus then frequency is faster, otherwise Slower.Its frequency limit resistance is that the minima to frequency-adjustable resistance has carried out certain restriction.

(4), the composition of duty cycle circuit and principle.

Duty cycle circuit is made up of steering diode series connection duty ratio resistance.

The meaning of dutycycle be pulse in a cycle, realize the allocation proportion to high-order time and low level time and adjust Whole.

Its principle is：

Vibration two gate output terminal within when impulse scaler is a high position, and one output of the vibration within impulse scaler When holding as low level, the electric current of the vibration two gate output terminal output within impulse scaler is through counting oscillating capacitance and frequency adjustment electricity The outfan of the vibration one within impulse scaler is arrived in the input of the vibration within road, impulse scaler one again, and formation is filled The electric loop.After charging terminates, the vibration one within impulse scaler is low level, and the vibration two within impulse scaler is height Position, so counting oscillating capacitance to carry out reciprocal discharge process, is that frequency adjusts branch road and duty cycle circuit through passage, by Two resistance values in frequency regulating circuit are far longer than the resistance of duty cycle circuit, so discharge current is mainly from discharge paths Pass through.So this is a reason in this circuit realiration dutycycle, another major reason is that the process of electric discharge is through one After the transmission of row door, finally implement interface audion（In Fig. 2 3.1）Current collection is extremely high, so discharge time is shorter, in pulse A cycle in, the time of charging is long, and the time of electric discharge is short, meets general requirement, so this is that discharge paths resistance is little, with When be also the main cause that dutycycle is built up in discharge paths.

Because generating unit has frequency-adjustable and dutycycle, so can realize relative to the charging being electrically charged pond Maximum scientific.

The Main Function that pulse resets unit is, when being energized every time, all pulse count device resets, and makes impulse scaler It is all accurate to count every time.

（4）, charhing unit feature and explanation.

1., the main idea justice of the composition of charhing unit and formation.

Tool maintenance statistics, is exactly execution Push And Release in this charge circuit for fragile elements in all of charger Audion.So having carried out emphasis process to this point in the present invention, this measure also becomes an important core of the present invention The heart.

Main it is made up of await your instructions circuit, charging switching circuit, charging operating circuit, base circuit of charging.

Charging await your instructions circuit by charging await your instructions manage（In Fig. 2 5.11）, charge the upper inclined resistance of pipe of awaiting your instructions（In Fig. 2 5.12）, charging switching circuit forms by several Diode series；Charging operating circuit is by the instrumentation tubes that charge（In Fig. 2 5.21） Upper inclined resistance with charging work（In Fig. 2 5.22）Composition；Base circuit is by the base diode of the instrumentation tubes that charge（In Fig. 2 5.51）, charge the base diode of pipe of awaiting your instructions（In Fig. 2 5.50）, lower inclined resistance（In Fig. 2 5.52）Composition.

Wherein charging switching circuit is formed by several Diode series, although this unit element is few, is waiting with charging Under the cooperation of life pipe, play highly important effect.

Charhing unit is a most important core in the present invention.Its reason is that the present invention devises such form, energy Make charging instrumentation tubes be in normal operating switch working condition at the very start all the time from be energized, and charge and await your instructions pipe unit then It is in " resting state " of open circuit, damage once charging instrumentation tubes and when quitting work, the pipe unit of awaiting your instructions of charging will automatically engage Work, therefore greatly improves the life-span of charger.

2. the reason, produce Unit two " ladder work " analysis.

For reaching purpose of design, the present invention is designed with following characteristics, and one to be that live part two audion all has independent upper Resistance partially, is resistance and the resistance connecing the sub- bias current of fulgurite of awaiting your instructions connecing for charging valve bias current, and its effect is after a pipe damages, Do not interfere with the working condition of second pipe.Two is that base stage to two pipes is designed with an identical inclined resistance（In Fig. 2 5.52）, its effect is that the base stage of two pipes all has an identical comparison voltage starting point, thus sets important for result described later Premise.Await your instructions to manage due to charging（In Fig. 2 5.11）Base stage, ratio charging instrumentation tubes under same voltage（In Fig. 2 5.21） Base stage will many two PN sections, its reason is that charging switching circuit made by two diodes of having connected, so the base of charging instrumentation tubes Pole tension awaits your instructions to manage higher than charging.Due to being less than PN section in triode emission ultimate ratio base stage, so the sending out of charging instrumentation tubes Emitter-base bandgap grading should be higher than charging pipe of awaiting your instructions, and when two pipe emitter stages are connected, the pipe of awaiting your instructions of charging will be sealed up a door, and that is to say that charging is awaited your instructions Guan Ji Pole and emitter stage are in reverse bias.Do not have output current.So charging is awaited your instructions, pipe is in the resting state of inactivity consumption. Under normal circumstances, charging tasks are only completed by charging instrumentation tubes.In the present invention, this pipe is " instrumentation tubes ".When charging instrumentation tubes After damage, when no current or amplification quantity are not enough, the Guan Yin of awaiting your instructions of now charging loses voltage of sealing up a door, immediately outside output current, real Show normal automatic switchover.Charger will not therefore be scrapped.Thus greatly increase the reliability of charger.

Additionally should illustrate at 2 points, one is because the life-span of audion in theory is very high, but due to audion itself Production process, and charger on the make to aspects such as the welding of audion the reason, or in use improper because Element, usually makes audion such life-span be challenged, does not reach theoretic requirement, and such automatically change jobs earnestly, The one kind exactly not reaching the high life to this audion makes up.Two is because two transistor parameters are consistent, is all place during work In the on off state opened Yu disconnect, thus either charging work pipe work, or charging pipe work of awaiting your instructions, it entirely charges Property will not change.Three is using a pipe（Charging in the present invention is awaited your instructions to manage）For dormancy shape, the power consumption of this pipe is approximate It is zero, and audion life-span and the power that it is consumed have very big relation, so being hardly damaged, and simpler than being adopted with two pipes Parallel relationship connect functional reliability much better.

Why charging switching circuit produces has two using two Diode series main causes, and one is that two diodes are sealed up a door There is bigger space, surplus is bigger, two is the sampling part that can become in batch production, when being to check this road no current, can With not turning off this branch road, table is connected in branch road, because operating inconvenience like that.And directly ammeter can be connected in parallel on diode Two ends can.

（5）, discharge cell feature and explanation.

1., the composition of discharge cell and meaning.

This unit by electric discharge await your instructions circuit, electric discharge operating circuit, electric discharge switching diode（In Fig. 2 12.7）, excision open Close circuit, discharge resistance（In Fig. 2 12.3）Composition.

Electric discharge operating circuit is by the work audion that discharges（In Fig. 2 12.11）, electric discharge work biasing resistance（In Fig. 2 12.12）Composition, discharge circuit is awaited your instructions audion by electric discharge（In Fig. 2 12.21）, electric discharge awaits your instructions biasing resistance（In Fig. 2 12.22）Composition, excision on-off circuit is by two excision diodes（In Fig. 2 12.82 and 12.83）With excision switch（In Fig. 2 12.81）Composition.

The meaning of discharge cell has three, thus also become the present invention with a core emphasis

In the overall process charging, the function again discharged, it is in a cycle of pulse, work as impulse scaler Internal vibration two（In Fig. 2 6.12）When being output as low level, interface audion（In Fig. 2 3.1）Colelctor electrode also be low Position, when charhing unit is in the halted state of open circuit, discharge cell conducting herein carries out spark to battery.Otherwise in arteries and veins In one cycle of punching, when charhing unit is in the conduction state, discharge cell herein is in breaking closed mode.Formed such Logical relation reason is that interface audion assume responsibility for logic function, has played buffer action to two parts simultaneously again.It is allowed to mutually not Impact.（Above interface audion unit is described in detail）.It is electrically charged pond and be in, in charging overall process, the state filled not only but also put, In the case that charge and discharge is proper, the maximum that its benefit can be achieved on charging is scientific.Even some electric properties can be allowed to be in Battery in the state of very poor, can be able to a certain degree of recovery.

2., in discharge cell, electric discharge operating circuit and electric discharge are awaited your instructions the meaning of switching of circuit and principle explanation.

Discharge cell is because in electric discharge, electric current is still larger, for avoiding in discharge cell electric discharge work audion flimsy Situation, so still employ electric discharge work audion and electric discharge await your instructions the form that audion coexists, in the work audion that discharges During operating discharge, the colelctor electrode of audion of awaiting your instructions due to discharging, because being in series with switch unit two, creates threshold value, so electric discharge electricity Stream will be discharged work audion passage " short-circuit ", and the audion branch road of awaiting your instructions of discharging then is in currentless " resting state ", Become the standby pipe that a kind of inactivity consumes.When charging instrumentation tubes are damaged and during open circuit, electric discharge audion of awaiting your instructions automatically engages Work, therefore greatly improve discharge cell life-span.

The base stage of discharge system is connected with excision switch over the ground, and after excision switch closure, discharge cell two audion has Supply voltage, becomes the reverse bias of discharge cell two pipe, so two pipes are not turned on, does not discharge.Setting up of this switch, increases Add the motility charged.
