Description

technical field

The invention mainly relates to the field of battery repair, in particular to a lead-acid battery resonant pulse repair instrument under various voltage conditions.

Background technique

Lead-acid batteries form lead sulfate crystals during discharge, and are easily reduced to lead during charging. If the battery is used and maintained poorly, such as undercharging or overdischarging frequently, a coarse and hard lead sulfate will gradually form on the negative electrode. This lead sulfate is difficult to restore by conventional charging. This phenomenon usually occurs at the negative electrode and is called irreversible sulfation. It will cause the battery capacity to drop, and even become the reason for the end of the battery life. The reason for this irreversible sulfation is the recrystallization of lead sulfate. When this happens many times, a layer of lead sulfate crystals similar to an insulating layer is formed. To break the bondage of these sulfate layers, it is necessary to raise the energy level of the atoms to a certain extent. At this time, the electrons added to the outer layer atoms are activated to the next higher energy band, so that the atoms are released from the bond.

The resonant pulse repair technology can repair the battery. The principle is to continuously emit positive and negative frequency conversion pulses while charging and discharging, which resonates with the lead sulfate crystals in the battery, so that the lead sulfate is vigilantly reduced to sulfate ions and lead ions. , Change the composition and properties of the electrolyte, reduce the internal resistance of the battery, and completely eliminate the vulcanization of the battery.

However, batteries with different lifespans require different repair voltages. Excessive voltage will easily lead to gas evolution of the battery, which will also cause damage to the positive plate of the battery, which will damage the life of the battery. If the voltage is too low, the energy level of breaking down the lead sulfate crystal will not be reached, and the effect of battery repair cannot be achieved.
