Embodiment
Below describe the present invention in detail.
In Fig. 1, represent a kind of embodiment of lead sulfate film removal device circuit structure of the present invention.Fig. 1 device is made of voltage detector, standard capacitance box, voltage comparator, work, inoperative switch, oscillator, amplifier, waveform shaping circuit, negative pulse current feedback circuit, energising display.Wherein, work, inoperative switch are switch designs, also can not.
In Fig. 2 kind, the waveform that A, B and C are ordered in the displayed map 1.On the C point, produce the negative pulse electric current of short pulse width,, lead sulfate film can be decomposed into finely particulate by sending it to lead accumulator with skin effect (skin effect).
Skin effect described here is meant that the high frequency electric current only is confined to the surface of conductors layer, does not enter inner phenomenon.Because this effect, charge concentration is decomposed into the finely particulate of lead ion and sulfate ion gradually from the skin section of lead sulfate film, the front end that is specially the overshooting shape crystallization of lead sulfate in skin depth (skin depth) scope that pulse duration determined.
Like this, lead sulfate film can not peeled off, come off from electrode as at present, perhaps still swims in electrolyte with crystalline state.
In addition, have the pulse current of the short pulse width of skin effect, be very faint electric current, can lesion electrode itself.And, also produce noise hardly, do not have the outside beyond the battery is produced dysgenic advantage.
In addition, owing to suppressed the generation of the Joule heat that sulfation causes, battery lead plate does not deform, and can prevent to generate heat from causing the dry of battery yet.
The pulse duration of the pulse current of device output can be applicable to the scope with skin effect.Specifically, 1 μ is below second, especially preferably is set in for 0.1～1 μ second.In this scope, because the skin thickness that becomes that is calculated is about 0.01mm, electric charge can not enter the inside of film, and concentrates on skin section.
Surpass 1 μ during second, thermal vibration takes place in the interface of lead sulfate film and battery lead plate, and its result causes the major part of film promptly to peel off, come off without dissolving, can not tell on.
In addition, the number of pulses of pulse current in case increase, can be accelerated the decomposition rate of lead sulfate film, still, owing to give birth to heat sometimes, considers the balance of these problems, and suitably sets.Specifically, be preferably per second about 8000～12000 times.The voltage of pulse current, current value too smallly then can not decompose lead sulfate film, otherwise excessively then give birth to heat and produce harmful effect, consider these problems and suitably set.Specifically, scope the best of 12～108V, 10～120mA, but owing to the difference of pulse duration and umber of pulse also is not quite similar, so do not do special qualification.
In addition, the power supply of device shown in Figure 1 also can be provided with external power supply in addition, but preferably so that this uses as power supply as the lead accumulator of installing.By consuming the small electric power of lead accumulator, prevent that effectively lead sulfate film from paying on electrode.
When being installed in said apparatus on the lead accumulator, as long as this device is connected on the battery lead plate of lead accumulator system of selection according to circumstances.Such as, can use cigar lighter shown in Figure 3 under the situations such as car, bus, truck.Perhaps, joint shown in Figure 4 directly can be installed on the lead accumulator with screw.
When lead accumulator is applied pulse current, perhaps apply after the pulse current, preferably charge again.Like this, by pulse current the lead ion of dissolving is once again reduced, as the electrode regeneration of lead or brown lead oxide.Consequently, the normal value of the proportion initial stages of restoration of electrolyte can recover the performance of battery rapidly.This effect has only to be decomposed into finely particulate by the skin section with film can to obtain such effect as the present invention, in the prior art, make under the situation that film peels off by electric shock, even charging, also lead sulfate crystallization once more can not produce this effect.
Charging is put pulse current and carries out simultaneously with dashing, and lead sulfate film is constantly decomposed, reduced, and can suppress increasing the weight of of sulfation, and keeps the performance of lead accumulator for a long time.
For the lead accumulator that decreases of a large amount of lead sulfate film, performance, after applying pulse current, charge, carry out this a series of program repeatedly, promptly can tell on.Like this, the lead sulfate crystallization of electrode surface is decomposed from skin section, forms spongyly, and the proportional increase of the proportion of electrolyte and application time can be with the performance recovery of the lead accumulator state to the initial stage.
More than, the lead sulfate film removal device that the present invention relates to can use on various lead accumulators.Specific embodiment as, the lead accumulator of the emergency wireless communication usefulness of the stand-by power supply of the facility of car, truck, bus, speedboat, motorboat, fishing boat, boats and ships, agricultural machinery and implement, construction instrument, construction implement, electric fork lift truck, Electric hand cart, golf troller, sweeper, electric motor car chair or hospital, bank, communication equipment etc., police, fire-fighting etc. etc., but be not limited to these.
Specific embodiment
The special-purpose pulse generator (12V, 120mW) that circuit structure shown in Figure 1 is housed is installed on the storage battery, dashes with the cycle of per second 10000 times that to put pulse duration (the T neg. of Fig. 2) be following pulse current 1 μ second, carry out the discharge of lead accumulator.In addition, current value is set at 10mA.
In addition, measure the time variation of lead accumulator output voltage.As a comparison case, the situation that does not apply pulse current has been carried out same mensuration.Its result such as table 1 and shown in Figure 5.
As table 1 and shown in Figure 5, connected the lead accumulator of embodiment device, compare with Comparative Examples, can in the longer time, keep certain voltage.In addition, as shown in table 2, the Capacity Ratio Comparative Examples of embodiment is big.Like this, as seen, apparatus of the present invention can prolong the life-span of lead accumulator.
In addition, when the inside battery situation of observing after discharging, in Comparative Examples, there is the lead sulfate powder to swim in the dilute sulfuric acid, also can sees some films on the battery lead plate, still, almost do not find the formation of lead sulfate film among the embodiment.
