The voltage of lead-acid battery BT for the input voltage range of the above-mentioned AD converter 106 of correspondence, carries out dividing potential drop by resistive element R3 and R4, and is provided with the capacitor C 3 of burning voltage after the dividing potential drop.Voltage after the dividing potential drop is to AD converter 106 input voltages.
Fig. 8 has showed the output waveform of above-mentioned pulse generating circuit 107, the voltage waveform of current sense resistor R2, the charging and discharging currents waveform of lead-acid battery BT.The voltage waveform of the output waveform of above-mentioned pulse generating circuit 107 and current sense resistor R2 is with the voltage reference GND(ground connection of lead sulfate attachment removal device 10) interface is expressed as 0V.And above-mentioned charging and discharging currents waveform for when discharge electric current be the negative direction waveform, be the positive direction waveform during charging.
Fig. 9 table is the relation between the output voltage of the dump energy of multiple rated voltage lead-acid battery and lead-acid battery.Be the lead-acid battery of 12V such as rated voltage, output voltage was 11.6V when dump energy was 10%, output voltage was 12.8V when dump energy was 100%, the output voltage when lead-acid battery is in overcharge condition is 13.0V.And the relation of output voltage also can suitably change based on the dump energy of Fig. 9 and the rated voltage of each lead-acid battery.
The output waveform of above-mentioned pulse generating circuit 107 shown in Figure 8, i.e. pulse output cycle T 1 and pulse amplitude Tw also can be subjected to the control of above-mentioned calculating control processing unit 105.Show such as Fig. 9 right column, according to the different dump energy of rated voltage, per second output umber of pulse also can be controlled.About the process of control, the lead-acid battery that utilizes a rated voltage among Fig. 9 for 12V is illustrated.
Fig. 4 has showed the handling process of above-mentioned calculating control processing unit 105.Interface P1, P2 are connected with the lead-acid battery BT of 12V, power and start working to lead sulfate attachment removal device 10 by battery.
Above-mentioned calculating control processing unit 105 reads the voltage Vx of lead-acid battery after by dividing potential drop by AD converter 106.Voltage Vx computational transformation according to the rules to dividing potential drop, the output voltage (step S101) of lead-acid battery BT.Here, because the rated voltage of lead-acid battery BT is known 12V, so variable V bt is set as 12(step S102).
Setting above-mentioned parameter Vbt is in order to judge the dump energy of lead-acid battery BT.Above-mentioned parameter Vbt is the magnitude of voltage that replenishes the lower voltage of circuit element deviation shown in Figure 1, the voltage drop that causes because of the resistance of wire L1, L2 such as comprising etc., after being read by above-mentioned AD conversion take Vbt as corrected value, just might be preserved by EEPROM or be convenient in use and read.
Above-mentioned calculating control processing unit 105 will be documented among the above-mentioned RAM, and the output voltage of the corresponding dump energy that draws based on Fig. 9 form forms and arranges variable V k(step S103 as critical value voltage).Shown in step S103, this is arranged variable V k and obtains variable V bt by utilizing the regulation multiplying power to calculate, thereby reduces the memory capacity of ROM and EEPROM.
The below carries out the initialization (step S104) of parameter, judges whether the dump energy of above-mentioned voltage Vx expires 100%(step S105).In the situation of dump energy less than 10%, pulse generating circuit will stop to export pulse (step S110), microprocessor 100 will stop all functions except doze output, open the park mode of stipulated time, after the power consumption of lead sulfate attachment removal device 10 dropped to minimum, (step S111) again brought into operation.In addition, in order to save the processing time from step S101 to step S110, with the work of stop pulse circuit for generating, to reduce power consumption.
When the dump energy of voltage Vx greater than 10% the time, will judge the variable V k arranged side by side (step S106) in what scope of critical value voltage among Fig. 9.Export umber of pulse driving pulse circuit for generating according to result of determination according to the per second of putting down in writing on Fig. 9 right column.Above-mentioned calculating control processing unit 105 will be set the cycle T 1(step S107 as the pulse generating circuit parameter).
Judge whether pulse generating circuit 107 is in halted state (step S108).During if pulse generating circuit 107 is in and stops, with regard to unbalanced pulse circuit for generating 107(step S109), according to the per second output umber of pulse that sets in the above-mentioned processing procedure, the output waveform of the pulse generating circuit 107 in the output map 8.
As mentioned above, calculate control processing unit 105 in the situation that the excessive increase of dump energy to the stipulated time output pulse that lead-acid battery discharges and recharges, improves the lead sulfate attachment and removes speed, accelerate releasing over-charging of battery electricity condition.In the situation that dump energy is less, reduce the output pulse in the stipulated time, prevent lead-acid battery BT overdischarge, suppress the power consumption of lead sulfate attachment removal device 10.And, calculate control processing unit 105 and during lowly near cut-ff voltage, automatically stop output voltage at the dump energy of lead-acid battery BT, prevent overdischarge.Although what judge the dump energy use is limited segmentation critical value voltage shown in Figure 9.But use the calculating formula of calculating the lead-acid battery output voltage for dump energy, also the continuous number exported of change pulse circuit for generating per second.
Below be based on Fig. 5 the specific embodiment of the present invention 2 is described.In explanation during embodiment 2, only identical place is omitted in the different place of explanation and embodiment 1.Fig. 5 further improves the step 102 among Fig. 4, is provided with the step of unknown rated voltage how to judge lead-acid battery.
Before key diagram 5, the column diagram of the scope of the final voltage of each rated voltage of Fig. 9 and charging voltage is shown in Figure 10.Among Figure 10, with the rated voltage of general many usefulness be 12V, 24V, change in voltage scope when the 48V lead-acid battery discharges and recharges, show in the mode of oblique line.As can be seen from Figure 10, if lead-acid battery is in normal condition lower time, the possible voltage range of the overcharge condition voltage after each final voltage and the charging can not overlap mutually.
The voltage of lead-acid battery can be learnt by above-mentioned AD converter.Can judge that by Fig. 9 its voltage belongs to the initial sum final voltage of which rated voltage, and the scope of voltage during overcharge condition.Judge thus the rated voltage of the lead-acid battery that lead sulfate attachment removal device 10 has been installed.For example, the voltage Vx that above-mentioned steps S101 obtains is more than the 10.5V, and during not enough 13.0V, the rated voltage that just can judge lead-acid battery BT is 12V.
Below begin to carry out the explanation to Fig. 5.Above-mentioned calculation control device 105 is inferred arrangement variable V ref(step S201 by the multiple load voltage value of EEPROM record).Parameter initialization (step S202) judges it belongs to which kind of rated voltage (step S203).Step S203 draws the voltage under final voltage and the overcharge condition to compare rated voltage as the basis, judges whether its voltage belongs in this scope.With the method whole arrangement variable V ref are judged (step S205, step S206) successively.When voltage Vx meets the condition of step S203, the rated voltage of lead-acid battery BT just can be determined, then substitution variable V bt(step S204), utilize the step S103 of Fig. 4 again to process, according to the lead-acid battery dump energy of rated voltage Vbt, just can carry out the later processing of step S103.
But can't detect the voltage range that oblique line represents on Figure 10 if determine the numerical value of Vref, this lead-acid battery BT is just very possible because overdischarge causes unusual voltage drop so, perhaps the rated voltage of this battery does not belong to fixed rated voltage as the Vref that arranges in advance parameter, so step will transfer from S206 the step 110 of Fig. 4 to.
Next begin to illustrate embodiment 3 based on Fig. 6, Fig. 7.The part different from embodiment 1 only is described when embodiment 3 is described, omits same section.In embodiment 3, illustrate about the processing that reduces, also fixing above-mentioned pulse discharges and recharges output umber of pulse in the required stipulated time by key diagram 6, Fig. 7.Fig. 6 is designed processing between the step S100 of Fig. 4 and step S101, makes zero when beginning timing again entry into service (step 301) at lead sulfate attachment removal device 10 starting the beginning timing.
Fig. 7 is the processing of replacing the step S107 of Fig. 4.At first, judge above-mentioned timer elapsed time (step S302), if do not pass through the set time, based on result of determination, the per second output umber of pulse driving pulse circuit for generating 107 of Fig. 9 right column record calculates the pulse output cycle T 1(step S303 that control processing unit 105 is set the pulse generating circuit parameter).
If result of determination, so just stops above-mentioned timer (step S304) for having passed through the set time, suppose that the pulse output cycle T 1 of pulse generating circuit parameter is 50 microseconds, so just per second is exported umber of pulse and be set as 20000.If. the pulse of pulse generating circuit parameter output cycle T 1 is set as the 1/2 also passable of per second output umber of pulse that Fig. 9 right column shows.
Below based on Figure 11 introduce the explanation embodiment 4.The part different from embodiment 1 only is described when embodiment 4 is described, omits same section.In embodiment 4, the circuit of Figure 11 is the waveform shaping circuit 102 of Fig. 1, an example of current-limiting circuit 103 internal circuits.Below the operation of the circuit of Figure 11 is introduced with the form of Fig. 8 waveform.
The part 110 that the chain-dotted line of Figure 11 surrounds is current-limiting circuits, is made of triode Q4, resistance R 8.Resistance R 8 links to each other with contact N1, the current sense resistor R2 of Fig. 1.
Except the part that Figure 11 chain-dotted line surrounds, waveform shaping circuit also comprises the push-pull circuit that NPN triode Q2, PNP triode Q3 etc. form.The pulse generating circuit of contact N2 and Fig. 1 joins.
As shown in Figure 8, after the pulse generating circuit output waveform changed to HI shelves (Vcc) from LOW shelves (0V), the earthed voltage of triode Q1, the Q2 that is connected with the contact N2 of Figure 11 rose by input resistance R5, speed-up capacitor C4.Triode Q2 is in "open" state thus, and triode Q3 is in "off" state.
When triode Q2 was in "open" state, its emitter voltage will rise, and just had electric current and flowed to capacitor C 5 from resistance R 6, and the gate voltage of triode Q1 will rise.This moment, the gate voltage of triode Q1 will begin to rise slowly along with the time constant that resistance R 6 and capacitor C 5 determine.Therefore triode Q1 just slowly the adjustment state be " opening ", it is large that the discharging current of the lead accumulator BT that connects with triode Q1 also will become slowly.
After above-mentioned discharging current began to flow, the voltage of the current sense resistor R2 that connects with triode will rise.The variation of at this moment Fig. 8 demonstration is exactly to form slowly resistance R 2 voltage waveforms.Although discharging current can increase always, but the voltage of internal resistance R2 will reach current limit shown in Figure 11 presents voltage between grounded emitter after the "On" state with triode Q4, the about V2 of 1.6V(Fig. 8), triode Q4 also can be in "open" state, the earthed voltage of triode Q2 just will reduce, so the gate voltage of triode Q1 will start the negative sense FEEDBACK CONTROL.Cause the electric current I 2 that flows through on the resistance R 2 with I2=approximately the formula of 0.6V/R2 show.When reaching this value, discharging current will be fixed.
According to the operation principle of foregoing circuit, discharging current can form certain restriction, therefore just might at short notice, put aside slowly certain pulse produce power in L1, L2 inductance coil.
Next, as shown in Figure 8, after the pulse generating circuit output waveform was transformed into LOW shelves (0V) from HI shelves (Vcc), the earthed voltage of triode Q1, Q2 that the contact N2 of Figure 11 connects will descend by input resistance R5, speed-up capacitor C4.Therefore triode Q2 will be in "off" state, and triode Q3 will be in "open" state.
When triode Q3 is in "open" state, its emitter voltage will descend, because the output of the emitter of triode Q3 does not have resistance, so the emitter voltage of triode Q3 will make capacitor C 5 discharge rapidly, cause the gate voltage of triode Q1 to descend rapidly.At this moment, triode Q1 is converted to rapidly "off" state, and the energy of putting aside in the inductance coil of L1, the L2 that connects with triode Q1 also can send pulse current to the back voltage direction, charges to lead-acid battery.
Circuit according to above-mentioned Figure 11 consists of, and just can realize that carrying out stable high-speed pulse to lead-acid battery BT discharges and recharges, and forms maximum pulse charging current, produces the effective impulse of removing the lead sulfate attachment.
Next according to Figure 12 embodiment 5 is described.The part different from embodiment 1 only is described when embodiment 5 is described, omits same section.In embodiment 5, Figure 12 is the output waveform when pulse-generating circuit 107 is made analog circuit.Above-mentioned analog circuit must comprise a pulse in above-mentioned cycle T 1, and remembers among Figure 12 that pulse generation time t1, t2, t3 can produce in above-mentioned cycle T 1 at random.The radiation of so external generation will be irregular unfixed disturbing wave, therefore can be very little on the impact that institute's connection device causes.
104 of Fig. 1 is announcers of the above-mentioned lead-acid battery dump energy of expression.Both can be used as liquid crystal display and represented to remain numerical value, also it can have been changed indicator light as 3 primary colors LED according to dump energy.
The whole bag of tricks discussed above has more than and is defined in above-mentioned formation, and refers to have the device of above-mentioned each function, does not limit to consist of and form.
The present invention is applicable to lead-acid battery lead sulfate attachment removal device.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
