The power supply is arranged on the circuit board and is electrically connected to an external power supply, and supplies power to the circuit board. The at least one resonant pulse unit and the at least one discharge line unit are arranged on the circuit board. The at least one microprocessor is arranged on the circuit board, and the interior of the microprocessor is provided with a first procedure in advance, and the first procedure is a positive / negative frequency conversion pulse procedure. The output unit is provided with a positive electrode electric clamp and a negative electrode electric clamp, the positive electrode electric clamp is clamped on the positive electrode of a lead-acid battery with lead sulfate crystals, the negative electrode electric clamp is clamped on the negative electrode of the lead-acid battery with lead sulfate crystals, the lead-acid battery is detected by means of the microprocessor, and the resonant pulse unit and the discharge line unit output at least one positive / negative frequency conversion pulse through the output unit, the positive / negative frequency conversion pulse and the lead sulfate crystals in the lead-acid battery resonate, and therefore the lead sulfate crystals are crushed.

Description

Technical field [0001] The invention relates to an energy-saving net electricity device, in particular to a composite lead-acid battery repairer which can achieve the purpose of energy-saving net electricity recovery by means of high and low voltages plus a resonance circuit. Background technique [0002] At present, the invention of lead-acid batteries has a history of more than one hundred years, and is widely used in various economic fields such as transportation, communications, electric power, military, navigation, and aviation. The main advantages are stable voltage, low price, and high market share. Relatively, at the end of battery charging, it is necessary to add acid, water, and other maintenance work. When the gas overflows during charging, it will carry acid gas to corrode surrounding equipment and cause air pollution. Although there are currently sealed lead-acid batteries that can save maintenance work and the problem of gas emission, their batteries will age. This ...

AI Technical Summary

Problems solved by technology

[0005] Chemical repair: For batteries that have been aged and sulfuric acid oxidized, pour out the original electrolyte, add pure water, sodium sulfate, potassium sulfate, tartaric acid and other substances, charge and discharge several times normally, then pour out pure water and add a little High-density acid adjusts the acid solution in the battery to the concentration of the standard solution. If the capacity is restored to more than 85%, the repair is considered successful, and the battery repair rate is about 45%. The disadvantages are: the repair procedure is complicated and the repair time is long. Water-filled lead-acid batteries cannot be repaired for sealed lead-acid batteries

[0006] Shallow cycle high-current charging: For aged and sulfated batteries, use a high current within 0.5~1.0 CA rate, allowing the battery terminal voltage to exceed the dehydration voltage during charging, and charge the battery to a slightly overcharged state to control the temperature of the liquid. Over 50 degrees, and then discharge 30%, repeated several times can reduce or eliminate the sulfuration of sulfuric acid, the battery repair rate is about 15%; the disadvantage is: this kind of elimination of sulfuric acid can only achieve a temporary effect, and will be in sulfuric acid During the oxidation process, the problem of dehydration and softening of the positive plate will be aggravated, which will seriously damage the battery life.

[0007] Pulse repair: For aging and sulfated batteries, pulse charging can be used to desulfurize batteries without loss, mainly including low-frequency pulses, high-frequency pulses (50% for battery repairs), and negative pulses (battery repairs are 50%). maintenance is 20%), compound pulse (battery repair is 60%) and other principles to remove sulfuration, as long as the battery is repeatedly charged and discharged, the capacity can be restored to more than 85%, which can be regarded as a successful repair; its disadvantages are: in addition to compound pulse and high In addition to high-frequency pulse repair, low-frequency pulse and negative pulse repair capabilities are poor, but composite pulse repair requires complex equipment technology and high cost

Only high-frequency pulse equipment is cheap, but the repair time is long (more than a few hours to a week), and it cannot be repaired for batteries with severe sulfuration.
