Technical field
The present invention relates to the solar charging power technology, relate in particular to a kind of method of controlling solar recharging.
Background technology
Common controller for solar adopts Programmable Technology, with the working method of control solar charging device to charge in batteries or driving loaded work piece.See also Fig. 1, the PowerPSoC of Cypress company series controller for solar is integrated programmable SoC (System on Chip, system level chip) technology, power electronic controller and switching device.Can substitute traditional M CU, system IC with and the discrete component of on every side One's name is legion, make the PowerPSoC solution use driving various loaded work pieces easily, comprise in the environment that storage battery is charged.Wherein, PowerPSoC is a kind of controller for solar.
Controller for solar major control method in the market has three kinds: break-make pattern, PWM type (impulse type), and MPPT type (maximal power tracing type).
Wherein, the break-make pattern approaches constant-current type to charge in batteries, and the PWM type is approximately impulse type to charge in batteries, and the MPPT type is that the constant voltage type is to the charge in batteries pattern.
Lead acid battery charge effect Analysis result of study is shown that pulse constant current is the higher a kind of method of charging gross efficiency, is superior to methods such as constant current, pulse constant current constant voltage, constant current constant voltage, constant voltage according to various.
Although the charge mode of PWM type relatively approaches the pulse constant current pattern in the controller for solar; But have load output owing to controller for solar is general long-term; The pulse current of its output is the impulse wave that has discharging current, and because duty ratio is continuous variation with the needs of battery tension, does not have the needs that prevent the storage battery concentration polarization; And this is harmful to, and this mode is the poorest a kind of of practical application effect in the middle of above-mentioned three kinds of patterns on the contrary like this.
Consider from the solar charging electrical efficiency that at present see also the content that one Chinese patent application CN200810058103.8 is disclosed, the chemical action diffusion motion is slow in the storage battery, causes concentration polarization, the hydrolysis of charging simultaneously produces hydrogen and surrounds negative pole, and oxygen surrounds anodal.
And if rise along with the electric weight of storage battery is lasting this moment, will make load current is strengthened, even can in the negative edge of pulse current charge, the situation of storage battery negative sense discharge occur.So further analysing of ohm, electrochemical polarization and the concentration polarization of aggravation storage battery seriously influence its charge efficiency, even the infringement life of storage battery.
There is the part controller for solar to adopt break-make pattern and PWM mould combination that storage battery is charged; Promptly; When battery capacity is not enough, adopt the long-time accumulators constant current charge of break-make pattern; When battery capacity adopts the PWM pattern to charge a battery during foot, but (discharging current) phenomenon that has negative current equally, to charge in batteries efficient and fullness rate also not raising.Though employing amplitude (2～4C) burst pulses (below the 0.0001S) discharge depolarization and the low amplitude value (method of 1～1.5C) burst pulse (below the 0.01S) discharge depolarization is also arranged; But the application of the big in short-term discharging current pattern of this realization is difficult to realize; Cost is also high; And the load current of PWM controller and pulse duration all can't satisfy, and load current is generally all in 0.001～0.5C, through the influence research of storage battery producer paired pulses electric current to charge in batteries; Impulse discharge current is big more, and the life of storage battery is unfavorable more.

In sum, at present the various charge modes of the used controller for solar of industry have following shortcoming:
1, the charge in batteries overall efficiency is undesirable;
2, can improve the PWM pattern of charge efficiency in some aspects, its negative sense discharging current has negative interaction to the life of storage battery, and its efficient is the poorest on the contrary.
Summary of the invention

The objective of the invention is to realize through following technical scheme:
A kind of method of controlling solar recharging, the two-way solar charging device charges to the storage battery of drive load equipment work at least, and every road solar charging device can adopt break-make pattern or pulse mode that storage battery is charged respectively; This method comprises the steps:
The break-make charge step: the solar charging device on all roads all adopts the break-make pattern, and storage battery is charged;
The mixed charged step: when the state of this storage battery surpassed first switching threshold, the solar charging device on part road switched to the pulse mode charging; Another part road still adopt the break-make pattern solar charging device charging current with, greater than the electric current of this load equipment;

The state of this storage battery surpasses the 3rd switching threshold, cuts off the corresponding output of adopting the solar charging device of pulse mode charging.
Wherein, First switching threshold, second switching threshold and the 3rd switching threshold can be provided with by the user in advance; In general, if when the value of the state of this storage battery is its capacity or voltage etc., first switching threshold, second switching threshold and the 3rd switching threshold increase progressively successively.Wherein, choosing of first switching threshold, second switching threshold can both combine the characteristic of storage battery to choose in advance.Like this, how to get into corresponding charge mode, its criterion is very simple, is guaranteeing to be convenient to commercial Application under the most measured future of final effect.
Technique scheme, solar charging device that can existing employing Programmable Logic Controller is set it according to the requirement of each step of said method, can improve charge efficiency on the whole, and overcome the influence of negative sense discharging current.
Promptly; Guaranteeing to adopt under the prerequisite of the total charging current in input road greater than load current of break-make pattern charging; Constantly break-make pattern and the input way that adopts the pulse-width-modulated mode charging are adopted in adjustment; And the width of the pwm pulse of the pulse-width-modulated mode of adjustment employing simultaneously, with charge efficiency and the storage battery fullness rate that guarantees to reach best.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment the present invention is described further.
A kind of embodiment of the present invention is following:
A kind of method of controlling solar recharging, the two-way solar charging device charges to the storage battery of drive load equipment work at least, and every road solar charging device can adopt break-make pattern or pulse mode that storage battery is charged respectively.This method comprises the steps:
The break-make charge step: the solar charging device on all roads all adopts the break-make pattern, and storage battery is charged;
Mixed charged step: when the state of this storage battery surpasses first switching threshold; The solar charging device on part road switches to the pulse mode charging; With the charging current that satisfies the solar charging device that still adopts the break-make pattern in another part road with, greater than the condition of the electric current of this load equipment;
Pulse mode charging controlled step: when the state of this storage battery surpasses second switching threshold; Correspondingly reduce the output of the solar charging device that adopts the pulse mode charging; With the charging current that satisfies the solar charging device that still keeps adopting the break-make pattern with; Greater than the condition of the electric current of this load equipment, up to
The state of this storage battery surpasses the 3rd switching threshold, cuts off the corresponding output of adopting the solar charging device of pulse mode charging.
As shown in Figure 3, be the structural representation of system among the another kind of embodiment of the method for control solar recharging of the present invention.Wherein, solar charging device adopts solar energy input square formation, and following solar energy input square formation also can be called square formation for short.
Four tunnel solar energy input square formation can select to adopt break-make pattern or pulse-width-modulated mode (PWM) that storage battery is charged respectively, then can adjust realization through the corresponding program to its controller.
Input condition according to the square formation of solar energy input at that time; Part solar energy input square formation adopts the break-make pattern; Promptly keep on-state for a long time; Here we are called the break-make pattern, are slightly larger than under the situation of load current in the total charging current in input road that guarantees charging, and all the other square formation input roads then adopt the pulse current charge pattern that storage battery is charged.And according to the situation of sunlight resource; Guaranteeing to adopt the total charging current in input road of break-make pattern charging to be slightly larger than under the prerequisite of load current; Constantly break-make pattern and the input way that adopts the pulse-width-modulated mode charging are adopted in adjustment; And the width of the pwm pulse of the pulse-width-modulated mode of adjustment employing simultaneously, with charge efficiency and the storage battery fullness rate that guarantees to reach best.Because so just become typical pulse constant current charge mode.
Under any charge condition, the pulse feature negative current can not appear at first; Secondly, when carrying out the pulse current charge pattern, the source of charging is a constant current state, and the characteristic at the maximum power point front end in the solar energy input voltage and input current characteristic is approximate constant-current source; At last, constantly adjust break-make pattern input way and pulse-width-modulated mode input way, make the lower limit of constant-current pulse as much as possible little, help storage battery and eliminate analysing of ohm, electrochemical polarization and concentration polarization.Thereby make the charge efficiency of storage battery high, charging rate is faster, and gassing rate is few, and temperature rise is low, the charge volume foot, and the life-span is unaffected.
Below we combine shown in Figure 1ly, further this embodiment is elaborated.Total input current (iON/OFF) on the square formation input road of break-make pattern is adopted in (A) expression among Fig. 1; Total input current (iPWM) on the square formation input road of pulse-width-modulated mode is adopted in (B) expression among Fig. 1; The total output current of load (iLOAD) is adopted in (C) expression among Fig. 1, and total charging current (iBATT) of storage battery is adopted in (D) expression among Fig. 1.
Begin charging when just; Battery capacity is in when putting the state of losing; Being the electric weight of storage battery lower the time, is to improve solar energy utilization rate, and the input of all solar energy input square formations all adopts the break-make pattern to charge; Switch in each road square formation input circuit all is in long conducting state, and storage battery is in constant current charging mode.The voltage-current characteristic of the input of storage battery is still in the constant current section, but its actual size of current can change with the variation of illumination condition, temperature conditions, environmental condition etc. to some extent.
, battery capacity then gets into the mixed charged step when being filled fullly; Like the t1 among Fig. 1 constantly; The switch condition of this entering mixed charged step can be chosen as the voltage of battery capacity or storage battery, reaches 80% or above or battery tension reaches specified float charge voltage or battery tension reaches the float charge voltage intermediate value or battery tension reaches Rule of judgment such as the float charge voltage upper limit like battery capacity.This switch condition is first switching threshold, and concrete employing can be selected according to the solar energy system configuring condition flexibly,, can choose than low capacity or low voltage than abundance or illumination condition better season like the solar energy photovoltaic panel configuration.Size according to every road solar energy input square formation input current; It is just passable that the total input current that makes the solar energy input square formation that adopts the break-make pattern import the road is slightly larger than the total output current of load; Be positive pulse charging completely when guaranteeing the PWM type mixed charged of back, adopt like this break-make pattern solar energy input square formation input road total input current near and again greater than the total output current of load for making up foundation.(understand calculating of sampling such as battery tension, charge in batteries electric current, every road square formation input current, load output currents in the controller for solar system, and battery capacity added up).All the other square formation input roads then adopt synchronous PWM pattern to charge; And carry out pulse-width regulated according to the voltage of storage battery; Can adopt fixed frequency also can adopt the PWM mode of change frequency; Here we think that the PWM mode of employing change frequency can be more excellent, because the enough storage batterys of the duration of low current charge are eliminated polarization in will guaranteeing to scheme, the elimination of special concentration polarization is the time that needs than long; Like 1 second even longer time, promptly to guarantee the duration of the elimination polarization of Δ t1, Δ t2, Δ t3.Like t2 among the figure constantly, and battery tension (or capacity) is when increasingly high, and pwm pulse conducting duty ratio is more little, or adopts duty ratio constant, the frequency change pattern, and promptly the PFM type is also claimed the frequency modulation(FM) type, or adopts PWM and PFM mixed mode.
When battery tension or capacity are increasingly high; Promptly surpass the 3rd preset switching threshold, the pulsewidth of PWM is less than minimum adjustable value, promptly; Break-make pattern or PWM type are limited because of switching tube number or driving force; The rising edge or the trailing edge of switch are longer, in the time of can having influence on minimum pulse width, then can turn-off the part input road of adopting the charging of PWM pattern.Adopt the input road of PWM pattern charging all to be turned off up to all.After this just only kept the input road of adopting the break-make pattern, charge mode is a constant current charging mode.If voltage continues to rise or capacity has been full state, and is then identical with the break-make pattern, progressively cut off the solar energy input, import the road total current smaller or equal to the total output current of load up to importing the solar energy that all is cut off or keeps.
When the electric current that causes the input of solar energy input square formation because of the variation of intensity of illumination or other condition etc. changes, can carry out the way on the square formation input road of break-make pattern and PWM pattern and adjust according to the actual current situation.The adjustment principle for the solar energy input square formation input total current that adopts the charging of break-make pattern near and to be slightly larger than the total output current of all loads be that optimum condition (helps reducing ohmic polarization, electrochemical polarization and concentration polarization etc., guarantees that the pwm pulse charging is that positive pulse is charged completely.); The PWM charge mode is all adopted on all the other square formation input roads; All adopt the switching pulse of PWM charge mode should be synchronous; So just can reach best big amplitude pulse current charge, the little electric current of pulse lower limit can prevent that the duration (like the Δ t1 among Fig. 1, Δ t2, Δ t3 etc.) that polarization and pulse lower limit keep should be greater than the anti-required minimum duration of concentration polarization of storage battery, and its representative value is 1 second.
Because the adjustment of way can be regarded as and add 1 integer successively and increase progressively; Then the variation of the electric current on its way is saltus step successively; Just greater than being meant; If the way of break-make pattern charging is less than this value, solar energy input square formation that then must the charging of break-make pattern is imported total current and is always exported less than all loads.
Also but fixed solar input square formation input road is break-make pattern or PWM pattern, and control can be simple relatively like this.
Above this mixed charged step also can be applicable in the complementary type sun controller; Like the wind light mutual complementing controller; In the various complementary controller of light-electricity complementary controller, featuring complementation of solar energy and fuel energy controller or the input combination of multipotency source; Partly import when the long-time continuous input is adopted in the input of the part energy and adopt synchronous positive pulse input pattern, reach the approximate requirement of the required pulse current charge of charge in batteries.
As shown in Figure 4, just begin like charging process, if battery tension or capacity are lower, like this, outside load equipment for utilizing solar energy more, rather than storage battery power supply.Four road solar energy input square formation is all carried out work with the break-make pattern; The charging current iBATT=i1+i2+i3+i4-iLOAD of storage battery; That is, i1+i2+i3+i4 is equivalent to the part of iON/OFF before t1 among Fig. 1, and iBATT is equivalent to the part of iBATT before t1 among Fig. 1.
When higher or capacity is expired when battery tension, when promptly this voltage or capacity surpass predefined first switching threshold,, then get into blend modes of operation, also claim the mixed charged step like i1 >=iLOAD.Then the work of break-make pattern is adopted in first via input, and its excess-three road input can select to adopt the PWM pattern respectively, or the PFM pattern, or PWM and PFM mode mixture pattern.At this moment, i1 is equivalent to the part of iON/OFF between t1～t2 among Fig. 1, and i2+i3+i4 is equivalent to the part between t1～t2 among Fig. 1.When battery tension continue to rise, when promptly this voltage or capacity surpass predefined second switching threshold.Then the input road duty ratio or the frequency that adopt PWM pattern or PFM pattern or PWM and PFM mixed mode are regulated; The charge in batteries current effective value is diminished; This moment, i1 was equivalent to the part of iON/OFF between t2～t3 among Fig. 1, and i2+i3+i4 is equivalent to the part between t2～t3 among Fig. 1.When battery capacity is full of or battery tension surpasses floating charge or all fills ceiling voltage, the state that promptly is regarded as this storage battery surpasses the 3rd switching threshold, and the 2nd, 3,4 tunnel square formation input switch duty ratios progressively approach zero, up to turn-offing fully.Be equivalent to the later part of t4 among Fig. 1.If be full of or before battery tension surpasses floating charge or all fill ceiling voltage in battery capacity; Solar illuminating intensity etc. changes; The input current change of each road input also changes; If become big, then can in four tunnel inputs, select one road electric current near but the break-make pattern is adopted on the input road that is slightly larger than load current, all the other adopt PWM pattern or PFM pattern or PWM and PFM mode mixture patterns.If electric current diminishes; Then four tunnel inputs select one road electric current near but the break-make pattern is adopted on the input road that is slightly larger than load current; As there be not the situation of single channel input current greater than load current; Then can select two-way or three road input current sums near but the break-make pattern is adopted on the input road that is slightly larger than load current, all the other adopt PWM pattern or PFM pattern or PWM and PFM mode mixture patterns.If 2nd, 3 tunnel square formation input current sums near and greater than load current; Then the 2nd, 3 tunnel square formation input switch management and control systems adopt the break-make pattern; 1st, the 4 tunnel adopt PWM pattern or PFM pattern or PWM and PFM mode mixture pattern, be equivalent to the part between t3～t4 among Fig. 1.If input current continues to change, then continue adjustment.If any three tunnel total current sums all are not more than load current, then all get into the break-make pattern, also be equivalent to the later part of t4 among Fig. 1.
Certainly, also can be according to state at work incipient stage storage battery, as this moment storage battery be not to put state thanks to, directly get into mixed mode at the very start and carry out work.Certainly, this can be regarded as still having carried out the break-make charge step, and promptly the solar charging device on all roads all adopts the break-make pattern, and storage battery is charged, and just the state of storage battery has satisfied first switching threshold rapidly, then gets into the mixed charged step.
In whole charging process, adopt the break-make pattern early stage, is constant current charge, adopts the pulse constant current charge mode mid-term like this, is the pulse constant current charging, and the later stage is adopted the break-make pattern, is constant current charge.This both guarantee the maximum use of solar energy, make charge in batteries efficient high simultaneously again, charging rate is faster, gassing rate is few, temperature rise is low, the charge volume foot, the life-span is unaffected.
Like this, the part input adopts break-make pattern charge mode partly to import the controller for solar control model that adopts PWM type (or PFM type or PWM and PFM mixed type) charge mode.
Break-make pattern charge mode is adopted in part input, and the summation of their input charging currents is slightly larger than all loads output total currents, and PWM type charge mode is adopted in the part input, and their pulse current is the controller for solar control model of synchronous positive pulse.
Elder generation as shown in Figure 1 or roughly the same adopts big electric current constant current charge (break-make pattern); And then adopting break-make pattern and PWM type mixed charged (positive pulse charging), storage battery is full of or adopts again during approaching being full of the charge mode of little electric current constant current charge (break-make pattern) at last.
Break-make pattern charge mode is adopted in standing part input, and PWM type charge mode is adopted in the standing part input, and the pulse current when getting into the mixed charged step is the controller for solar control model of synchronous positive pulse.
Flexible configuration is partly imported and is adopted break-make pattern charge mode, flexible configuration partly to import to adopt PWM type charge mode, and the pulse current when getting into the mixed charged step is the controller for solar control model of the maximum synchronous positive pulse of amplitude.
Said method also is applicable to dissimilar controller for solar such as honourable type controller for solar, photoelectric type controller for solar, gloss oil type controller for solar, wind photoelectric type controller for solar.Can wind energy be exported, the direct current output of the output of the module of power-supply system or oily machine control system is as break-make type input road, and the solar energy input is adopted the pulse mode input and carried out corresponding charging control, also can reach the effect of improving charging.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
