Battery repair method is very important, the best way is to add distilled water, using pulse method for sulfur removal, and then according to the actual situation of the battery to do other technical treatment, this is the real non destructive repair. Theoretical analysis and practice show that it is normal to use the battery for 6 to 8 months after complete repair. One is the high voltage and high current pulse charging, through the negative blocking to eliminate sulfide. In the energy state of covalent bond chaos, sulfur exists in the annular molecular form that contains 8 atoms of the 8 atoms of molecular ring mode is a combination of chaos, difficult to jump and was broken, the level is not the phenomenon of sulfide battery chaos. 2 full charge full release repair method (deep discharge repair): full charge full release repair method is to take full battery after the special battery,
Method for repairing full discharge. From the perspective of overcoming the polarization, the negative pulse time is very short, usually in time is about 5% of the positive pulse, the amplitude is 1.5~3 times the positive pulse. The method and principle of battery repair in 1859 the French physicist Plante invented the lead-acid battery has been extraordinary, prolonging the service life of the battery has become a major topic for people to study, long-term practice, people use a lot of ways to remove the battery plate sulfide, summed up under several:
1: the current charging current charge, the method of lead sulfate crystals dissolving the experiments showed that this method eliminate the sulfide can only get temporary effect, and will bring increased water loss and eliminate problems in the softening of positive plate vulcanization process, cause serious damage to the battery life, now rarely used method this simple battery repair. The mechanism of water reducing lead sulfate solution saturation, with lower solubility product of sulfate acid density progress, take a long time to reduce the small current charging voltage delay ohmic polarization of the decomposition of water thrown up early, and ultimately to eliminate the phenomenon of sulfide as active substances in gradually reduce or in dissolution and transformation, according to this theory if the charge, with high current, the battery temperature is controlled at about 45 DEG C, and oscillation can increase the solubility of lead sulfate, accelerate the electrochemical reaction rate, sulfur removal effect is more significant. 4: adding surfactant to sulfide battery into water and sodium sulfate, potassium sulfate, tartaric acid and other substances mixed liquid, take charge and discharge normally several times, and then poured water with slightly high density acid in acid solution to adjust the cell concentration scale, capacity to recover more than 80% can be successfully repaired. If the conductance difference, high voltage resistance of sulfate salt applied moment, can breakdown large lead sulfate crystals.
From the view of atomic physics, the sulfur ion has 5 different energy levels, and the ions in the state of the neutral state tend to move to the non existence of the covalent. To break the structure of these layers, it is necessary to provide a certain amount of energy to the ring molecules, so that the outer layer of atoms with the band of electrons are activated to the next high energy band, so that the release of atoms between the shackles.
The vast majority of battery manufacturers are produced by the national battery testing standards, the general life should be about 3 years. Another method is to use a small current frequency of up to 8KHz, the use of large crystal resonance method to dissolve, this method is relatively slow repair, repair effect is also good, but,
Repair time is relatively long, often more than 120 hours. The formation of the compound in the acidic medium is not chaotic, non conductive sulfide layer will be gradually dissolved into the solution. However, the old battery does not apply, due to the precipitation of the gas in the washing of sulfate, but also on the positive plate of the active substance to produce a strong wash, so that the active material becomes soft or even off. Repair lead-acid battery repair process extraordinary 1 steps: battery repair can be roughly divided into four steps, selection, judgment, repair, inspection: is the battery initial selection, selected will no repair of the value of the battery, reduce the blindness of repair. This method, with the charge of the gas to the surface of the plate to wash a little sulfide salt, so that it is dissolved and dissolved into active substances. In addition, it has been proved that any combination of pulse mode will be beneficial to improve the repair effect.
Repair of extraordinary battery is often encountered in electric vehicle maintenance problems, one of the problem of the battery repair can repair is also more concerned about the user, through the practice in recent years, people basically affirmed the positive significance of the extraordinary battery repair, the first user can reduce spending, reduce the cost of the battery, then provide repair extended battery life can reduce battery consumption the amount of saving resources, reduce pollution. Each level has a specific resonant frequency of a resonant frequency, outside energy is too high will make the transition of the atom is not stable, low energy is not enough to make the atoms bound out of atoms, so pulse repair apparatus in the frequency change many times as long as there is a time to produce resonance with the sulfur atom, can the sulfide protons into free ions dissolved in the electrolyte, transformed into active substances in specific condition, re involved in the electrochemical reaction. Once the insulation layer is broken, it will change from the insulation state to the conductive state. This method is fast, effective, but the impact on the battery life is relatively large. According to the summary of a great deal of experience in electric vehicle battery general in the 8 months of use, it will float to the surface water, after 2 months, or 10 months, may be thrown curing phenomenon, this time is the best time to repair the battery. This method is special to open type
