Operation principle explanation：

After energising, impulse generating unit control interface triode（In Fig. 2 3.1）, so that charhing unit is entered to being electrically charged pond Row charges not only but also stops the charging work filled.

In charging process, because impulse generating unit work, constantly control the charging instrumentation tubes in charhing unit（Fig. 2 In 5.11）In opening and off-state, so whole work process is the pulse current charge adopting.

During pulse charge, the charging physical process of employing is, there is charging not only but also exist stop filling special Form.The charge rule being formed is, within a cycle of pulse, when the current collection extremely low level of interface triode, fills Electric unit is closed, and stops charging, and when the current collection of interface triode is extremely high-order, charhing unit is open-minded, charges to being electrically charged pond, Because, within a cycle of pulse, the time of charging is long, and the time stopping filling is short, so charging process is in pulse charge State.Such charging modes are conducive to the scientific maintenance to battery, the battery of damage are also had a certain degree of extensive simultaneously Multiple effect.

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

After battery is fully charged, after the side pressure of battery exceedes the threshold value that pressure limiting threshold cell is formed, pressure limiting threshold cell Start, output high pressure is by interface triode all the time（In Fig. 2 3.1）Triggering, the current collection extremely zero of interface triode, clamper charges Instrumentation tubes（In Fig. 2 5.11）Base stage, charging instrumentation tubes end, stop charge, now by trickle resistance（In Fig. 2 30）To Being electrically charged pond provides the trickle maintaining.

Line feature is analyzed：

1st, interface unit.

This unit is by interface triode（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 triode is triggered by two-way, and an output of a route pulse counter is defeated through extra pulse Go out diode（In Fig. 2 6.25）Triggering, another route pressure limiting threshold cell triggering.Thus interface triode mainly produce following Function：

One is that the direct current of charging is become pulse charge stream.Its reason is in pulse counter（In Fig. 2 6.0）Swash Encourage down, through the transmission of this triode, 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 output end 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 the ultimate control pipe becoming charhing unit, and after battery is fully charged, the side pressure of battery exceedes pressure limiting threshold value list After the threshold value that formed of unit, pressure limiting threshold cell starts, and output high pressure is by interface triode all the time（In Fig. 2 3.1）Triggering, connects The current collection extremely zero of mouth triode, clamper charging instrumentation tubes（In Fig. 2 5.11）Base stage, charging instrumentation tubes end, stop filling Electricity.

Three is excitation charging process indicator 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 triode current collection at the end of charging Extremely low level, charging process shows that luminous pipe range is bright.

2nd, pulse counter and impulse hunting unit.

A, its Main Function are the features of pulse counter and impulse hunting unit is to be not only a clapp oscillator, online Frequency not only can be adjusted in road, and dutycycle can be adjusted.

Pulse counter and impulse hunting unit have 3 points of effects in the present invention, and one is by interface triode（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 triode Control charging process indicator lamp（In Fig. 2 2.2）, form charging process instruction.Three is the regulation realizing dutycycle.Make charging Overall process, is realizing charging again and is stopping the recombination process filling, remain optimal ratio state.

B, principle composition and feature.

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

Vibration within pulse counter for the oscillating circuit one（In Fig. 2 6.1）, the vibration two within pulse counter Door（In Fig. 2 6.2）, with counting oscillating capacitance（In Fig. 2 6.3）, count oscillating capacitance series resistance（In Fig. 2 6.8）Group Become, frequency regulating circuit is by frequency limit resistance（In Fig. 2 6.4）Series connection frequency-adjustable resistance（In Fig. 2 6.5）Composition, accounts for Sky is than circuit by steering diode（In Fig. 2 6.6）Series connection duty ratio resistance（In Fig. 2 6.7）Composition.Wherein pulse counter Internal two wherein first is the vibration one within pulse counter（In Fig. 2 6.1）, second be pulse counter Internal vibration two（In Fig. 2 6.2）.

Wherein by frequency limit resistance（In Fig. 2 6.4）Series connection frequency-adjustable resistance（In Fig. 2 6.5）Constitute frequency Adjustment circuit simultaneously can achieve frequency-adjustable.Oscillating circuit forms the principle vibrating, the vibration within when pulse counter two When being output as a high position, by counting oscillating capacitance, discharge and recharge branch road, and vibration within to pulse counter for the discharge paths one Output end, be split into the charged state counting oscillating capacitance, the central point now connecting, be to count oscillating capacitance and counting The tie point of oscillating capacitance series resistance, for a high position.The input leading to the vibration one within pulse counter is a high position, directly To the end vibrating 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 output end of the vibration one within pulse counter is changed into high from low filling, at this moment in pulse counter The output end 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.

C, 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 pulse counter is a high position, and one output of the vibration within pulse counter When holding as low level, the electric current of the vibration two gate output terminal output within pulse counter is through counting oscillating capacitance and frequency adjustment electricity Road and duty cycle circuit and flow into vibration one gate output terminal pulse counter 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 minimum of a value to frequency-adjustable resistance has carried out certain restriction.

D, 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 pulse counter is a high position, and one output of the vibration within pulse counter When holding as low level, the electric current of the vibration two gate output terminal output within pulse counter is through counting oscillating capacitance and frequency adjustment electricity The output end of the vibration one within pulse counter is arrived in the input of the vibration within road, pulse counter one again, and formation is filled The electric loop.After charging terminates, the vibration one within pulse counter is low level, and the vibration two within pulse counter 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 triode（In Fig. 2 3.1）Current collection is extremely high, so it is shorter, in pulse to stop the time of filling A cycle in, the time of charging is long, and the time stopping filling 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 pulse counter It is all accurate to count every time.

3rd, pressure limiting threshold cell.

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 start diode（In Fig. 2 8.5）Composition：Resistance is partially adjusted on pressure limiting Partially limiting resistance, a termination charhing unit output in series connection pressure limiting, the other end is pressure limiting start end, connect under pressure limiting inclined resistance to Line, pressure limiting starts the other end that diode is connected on pressure limiting start end and interface resistance.

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, by interface triode（In Fig. 2 3.1）Triggering, makes the colelctor electrode of interface triode be always low level, charge closing unit.

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 minimum of a value.

The present invention has the advantages that prominent after implementing：

1st, by the present invention be to be electrically charged pond achieve science charge, enhance maintenance, extend the life-span being electrically charged pond, Decrease scrappage.And both products, either chargeable battery, or supporting charger, it is all that the modern life generally should Species, so the environmental protection of two kinds of products can be strengthened.Environmental protection no minor matter, so the present invention has positive effect.

2nd, also there is important economic worth, for the value of common electronic product, product as this kind of in charger, do not having Have 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 this Bright increased element is limited.After this measure is implemented, one is to be electrically charged pond life, and two is that capacity will not occur substantially to become Change, therefore society is bound to accept, and recognizes its scientific value, therefore this excellent product can replace the product of inferior quality.Due to existing In generation life, this product purpose is extremely widespread, so significant economic worth can be produced.

3rd, using the charged form filling but also stop not only, there are significant maintenance effects to being electrically charged pond, some critics claim on the net can Rechargable battery is to be filled bad, rather than damages, and this measure can close the relative maximum scientific maintenance of charging being electrically charged pond, spy It is not to acid battery.And with such charging, stop the mode of filling, the capacity of battery and life-span can not only be made will not to reduce, or even Defective cell is enable to obtain a certain degree of recovery, so meaning is very big.
