Single-chip microcomputer U1 can control simultaneously by the plastic drive circuit 2 of two groups of same structures, electronic switch 3, protective circuit 5 and DC power supply 6A, can repair two high-capacity sealed formula lead acid accumulators simultaneously, can not produce interference each other.In the present embodiment, the upper left corner shows plastic drive circuit, electronic switch, protective circuit and another DC power supply 6A (not shown) of another group identical set in Fig. 2, uses as the reparation of another Battery pack.Display circuit 4 is shared, and the I/O port can connect the single chip circuit 1 of 4 same circuits structures, and the lossless repairing device of every high-capacity sealed lead-acid battery can reach the output of 8 road same structures at most, can repair 8 high-capacity lead-acid storage batteries simultaneously.
Be depicted as to system's direct current power source supplying power circuit 6 as Fig. 2 upper right corner, when mains switch SW1 is closed, civil power one tunnel through DC power supply 6A (charging current is provided) be transformed into the constant voltage electric current that is fit to the maintenance battery (+5V/5A).Another road (Control current is provided) obtains DC18V left and right sides voltage through fuse F2 and power transformer B1 output AC15V voltage after bridge rectifier BR1 rectification C0 filtering, obtain 12V voltage through the U4 voltage stabilizing and supply with relay K 1 coil and plastic drive circuit 2.After the U5 voltage stabilizing, obtain 5V voltage again and supply with single chip circuit 1 and display circuit 4.
When the work of this device, 1,2 pin of the binding post CON7 in the protective circuit 5 link to each other with the short circuit of anode post, and 3,4 pin link to each other with the short circuit of battery cathode post; Cell voltage directly enters the A/D mouth of U1 through 2,3 lines of CON7, reduces the measure error that the line stopband comes.Polarity connects when correct, the diode D3 positively biased conducting in the polar protective circuit 5, cell voltage makes triode Q6 conducting through R9, R10 dividing potential drop, relay K 1 coil gets electric, the closing of contact, make electronic switch 3 electric, voltage is added to the Q5 drain electrode.Simultaneously, the port A/D2 of single-chip microcomputer U1 (another road is A/D1) detects cell voltage, begin startup work, and with detected cell voltage, (RT1 records the battery context temperature voltage by thermistor, import into through the Tsense of single-chip microcomputer U1 port with the R4 dividing potential drop) be input to U1, make comparisons with the float charge voltage of setting.
If the actual measurement voltage of battery is lower than the float charge voltage of setting, then single-chip microcomputer U1 is 120uS through port Pwm1 (another road is Pwm2) output in a string cycle, and duty ratio is that 95% control impuls is supplied with the Q4 in the plastic drive circuit 2; Export high level simultaneously, make diode D5 light indicating operating status.If battery actual measurement voltage is higher than the float charge voltage of setting, then exporting high level lights diode D6, single-chip microcomputer U1 output simultaneously is in the minimizing pulse duration (duty ratio) of constant situation downstairs formula of cycle, minimum duty cycle reduces to 5%, if this moment, battery terminal voltage also continued to rise when surpassing stop voltage, the port Pwm1 of single-chip microcomputer U1 stops output, and electronic switch 3 turn-offs, the battery two ends that do not have pulse current to be added to be repaired, battery terminal voltage falls after rise.
Resistance R 6, R7, the triode Q4 paraphase of pwm pulse in plastic drive circuit 2 by single-chip microcomputer U1 output amplified.Acceleration of being made up of resistance R 8, capacitor C 8, trigger U3 and shaping circuit 2 are supplied with electronic switch after the paraphase shaping again with pwm pulse and are driven, controlled the continuous conducting of switching tube Q5 and ended, made the direct current of DC power supply 6A become in check pulse current and be added to the two ends that are repaired storage battery.
After single-chip microcomputer U1 does the A/D conversion with detected battery virtual voltage, interconnect by the connector CON4 of FPDP and the connector CON5 of display circuit 4, I/O mouth disp1, the disp2 of I/O mouth disp1, disp2 and display circuit 4 are connected to each other, and transmission communication data, the real-time battery terminal voltage that single-chip microcomputer 1 is handled shows (DS2A, DS3A, DS4A among the figure) by the charactron in the display circuit 4 and illustrates, and allows the user get information about the reparation situation of battery.
The present invention is through using contrast, and effect is as follows:
Compare with existing small-pulse effect electric current prosthetic device, because the with good grounds cell voltage of apparatus of the present invention and environment temperature auto-adjustment control are repaired the single-chip microcomputer U1 of pulse current, so it is very big that its inceptive impulse electric current can be chosen, and reaches 0.1%～0.5%C10(C
10Nominal capacity for battery 10 hour rate currents discharges) even bigger, can accelerate the maintenance process. The lead sulfate crystallization that 200Ah～1000Ah only need just can remove clean inside battery in 48 hours to 168 hours. Work as terminal voltage When reaching sealed cell gassing voltage, monolithic U1 can reduce the dutycycle of control impuls automatically, namely reduces electric current. Very To cutting off electric current fully, damage to sealed cell prevents from overcharging; And existing little current impulse prosthetic device, because Taking the later stage into account overcharges to the impact of battery, and its pulse current is generally chosen very little, about 0.01%～0.05%C10, from Begin to guarantee that also battery can not overcharge, but remediation efficiency to fall obviously to the small-pulse effect electric current battery being repaired eventually Low, the lead-acid accumulator of same capability often needs just can embody effect more than three months.
