Repair the general work flow process of module: bring into operation when single-chip microcomputer receives enabling signal, the voltage signal being repaired battery 5 is made comparisons by sending with standard of precision voltage circuit the reference voltage come to, the change in voltage being repaired battery 5 accurately detected, according to the change of this voltage, generating one-period from single-chip microcomputer is 120uS, amplitude 5V, duty ratio is by the oscillating impulse square wave of 10% ~ 99% change, port is driven to export from PWM, the base stage of triode V104 is delivered to when oscillating impulse is high level, make the triode V104 degree of depth saturated over the ground by triode V104 emitter, now, the collector potential of triode V104 is about 4.4V.The current constant that constant-current source exports AC-DC POWER is at 0.1C10 (A), through the collector electrode of 5V voltage stabilizing didoe pipe D101, resistance R109 to triode V104, voltage-stabiliser tube D101 is in reverse breakdown voltage stabilizing state, defines 5V forward bias make its conducting to switching tube V101.Owing to there being the junction capacitance of about 2000pF as the TMOS pipe G pole of switching tube V101 and S pole, in order to overcome the delay on the settling time of junction capacitance formation, cause switching tube V101 magnifying state stop long and increase switching tube V101 pipe consumption, be speed-up capacitor with resistance R103 shunt capacitance C101, make switching tube V101 in rapid conducting.V101 conduction period, electric current is charged to being repaired battery 5 by D102.Otherwise, when single-chip microcomputer output oscillating impulse is low level, triode V104 proceeds to cut-off, triode V103 makes the emitter of triode V103 be in low level by resistance R105, and its base stage is in+5V, make triode V103 saturation conduction, the collector electrode of triode V103 is about 4.5V, triode V102 saturation conduction is made by resistance R104, the collector and emitter of triode V102 makes the S-G pole short circuit of switching tube V101, the junction capacitance of 2000p is discharged rapidly, and switching tube V101 ends rapidly, and electric current stops being charged to being repaired battery 5 by diode D102.Under the pulse current effect of this Fast transforms, the lead sulfate crystalline solid formed in battery pole plates can be made to decompose gradually and again participate in electrochemical reaction, thus can recover the charged capacity of storage battery.
In order to ensure that to be repaired battery 5 injury-free in repair process, except the pulse maintenance electric current needing considered critical maximum must be less than except 0.1 C10 (A), also need progressively to reduce pulse current after battery terminal voltage is higher than nominal voltage 2.45V, slow down side reaction.The control method that the present invention reduces pulse current is: before the terminal voltage of battery does not reach and analyses vapour voltage 2.45V, maximum (99%) duty ratio is adopted to export, once battery terminal voltage is more than 2.45V, often raise 0.12V then reduces 10% duty ratio by Single-chip Controlling, until when duty ratio is reduced to minimum value 10%, judge that repair process completes.If detect that the terminal voltage being repaired battery 5 rises too fast, then judge that this battery is that interior resistive is large, sulfation is very serious, now no longer control to export pulse duty factor according to the change of battery terminal voltage, but start timing routine reduction pulse duty factor, often reduce 10% pulse duty factor, timing working is after 30 minutes, continue again to reduce the duty ratio of next grade, until finally duty ratio be reduced to be worth 10% most time, judge that repair process completes.Now close and repair pulse output, the terminal voltage of a static 30 minutes repetition measurements storage battery, if voltage drop is to below 2V, then single-chip microcomputer sends instruction to Surveillance center by PORT COM and notifies that this joint cell needs to scrap; If this voltage is higher than 2V, then exports high level signal from PWM-IN port and drive detection module to enter operating state, discharge examination capacity is carried out to the storage battery repaired.
The control procedure of above-mentioned switching controls module 7 is as shown in Figure 3:
Whether the terminal voltage of the first step, detection storage battery is greater than 2V, if result negative, turns second step, otherwise turns the 3rd step;
Second step, storage battery to be repaired, after having repaired, storage battery is charged, until charging complete, and terminal voltage detecting is carried out to storage battery, if also do not reach 2V, then directly scrap, otherwise turn the 4th step;
3rd step, storage battery to be charged;
Whether the 4th step, detection battery capacity, be greater than 80% of nominal capacity, if result is affirmative, then repaired, otherwise, turn to the 5th step;
5th step, storage battery to be repaired, after having repaired, storage battery is charged, until charging complete, detect battery capacity, whether be greater than 80% of nominal capacity, if result is affirmative, then repaired, otherwise, scrap storage battery.
Specific works process is: be connected in the present invention by storage battery 5, voltage and nominal capacity two parameter informations of this battery are set at detection module 2, switching controls 7 in switch matrix 4 is the A of positive and negative for storage battery two ends by K switch 1, B contact change-over is to the output of charging module 1, as shown in Figure 2, detect the terminal voltage of this battery, if be less than 2V, then send instruction and control diverter switch K1 storage battery by contact E to controlling switching 7, F is connected to and repairs the pulse reparation that module 3 carries out one-period, now test side voltage is still lower than 2V, then judge that this battery belongs to waste battery, terminate the operation to this battery.After one-period reparation or the voltage of battery own be greater than 2V and then start charging procedure this battery is charged, instruction is sent to switching controls 7 after charging complete, control diverter switch K1 the both positive and negative polarity of storage battery 5 by contact C, D is switched to the output of detection module 2, the actual capacity of 10 hour rate current discharge examination batteries is carried out according to the parameter set in advance, (such as: the battery information of setting is: 2V/200Ah, then according to detection electric current 20A, the condition of final voltage 1.80V carries out constant-current discharge measurement capacity) detect and terminate, the actual capacity of battery is become according to the time noise of record, (computational methods: actual capacity Ah=discharging current I* T discharge time) also compare with the battery information arranged, (comparative approach: K volume percent=C1 actual capacity/C0 nominal capacity * 100%) is when K value is greater than 80%, judge that this battery of prompting is spec battery, terminate the operation to this battery.If K value is less than 80%, then send instruction to switching controls 7 the A of positive and negative for storage battery two ends by K switch 1, B contact change-over charges to the output of charging module 1 to battery, send instruction control switching 7 after charging complete and control diverter switch K1 storage battery by contact E, F is connected to and repairs the pulse reparation that module 3 carries out one-period, reparation completes, send instruction again to switching controls 7, control diverter switch K1 the both positive and negative polarity of storage battery 5 by contact C, D is switched to the output of detection module 2, the actual capacity of 10 hour rate current discharge examination batteries is carried out according to the parameter set in advance, (such as: the battery information of setting is: 2V/200Ah, then according to detection electric current 20A, the condition of final voltage 1.80V carries out constant-current discharge measurement capacity) detect and terminate, the actual capacity of battery is become according to the time noise of record, (computational methods: actual capacity Ah=discharging current I* T discharge time) also compare with the battery information arranged, (comparative approach: K volume percent=C1 actual capacity/C0 nominal capacity * 100%) is when K value is greater than 80%, judge that this battery of prompting is spec battery, terminate the operation to this battery.So circulate through the actual capacity of storage battery after 3 maintenances also lower than nominal capacity 80% time, judge that battery is scrapped, terminate the operation to battery.
