How to activate lead-acid batteries

The electric vehicle battery is activated. Now it is said that the electric vehicle battery is repaired. The specific methods are as follows: How to activate the electric vehicle battery? Use large current charging to make the large lead sulfate crystals produce negative resistance breakdown to dissolve. It has been found in the experiment that this elimination of vulcanization can only obtain a temporary effect, and will cause aggravation of dehydration and softening of the positive electrode plate during the elimination of the vulcanization process, causing serious damage to the battery life and being difficult to adopt. How to activate the tram battery? Negative pulse method has been applied for more than 30 years. The principle is to add a negative pulse during the charging process, which has an effect on reducing the temperature rise of the battery, but the repair effect on the "vulcanization" is not obvious. The repair rate is 20%, currently used more, is a phase-out product, the regular price is about 1300 ~ 1600Yuan.

How to activate the electric vehicle battery? Adding the active agent by chemical method to eliminate lead crystallization, not only high cost, increase the internal resistance of the battery, but also change the original structure of the electrolyte, the use period after repair is short, and the repair rate is about 45%.

How to activate the electric vehicle battery? High-frequency pulse by pulse wave to tiny lead sulfate crystals back into crystal, the electric chemical high reversible lead sulfate, the charging and discharging chemical reaction, make its can participate in normal repair rate is about 60%.A negative pulse effect is good. But because of the repair time is long, need ten hours, or even a week's time, the efficiency is low, the serious "cure" battery repair is not good, but the technology is simple, there are now many manufacturers use, the market price is about 2000 Yuan.

How to activate the electric vehicle battery? Combined resonance pulse reasonable control on the leading edge of the pulse, using pulse charging higher harmonic and the lead sulfate crystallization of resonance, the method of sulfide in the repair process to eliminate battery, using this method can give the battery repair, repair of high efficiency and little damage to the battery. It can reduce greatly the lead-acid battery pollution to the environment, extend battery life, reduce the user due to replace the battery to bring the huge cost, so the broad prospect. Defect is equipment technology is complex, high cost, pulse front control and higher resonance technology requirements. Market price about - 4 (4 independent filling) of 2200-2200 Yuan, - 20 (20 charged only put independent) for 8500-15000 Yuan.

Traction battery how to activate the resonance method to eliminate the principle and method of sulfide compound even though we know that prevent the battery sulfide is the main method to prevent the battery charge and discharge, not in time but in actual use, this kind of phenomenon is often happen. Before this happens is considered to be "irreversible". The traditional processing method is more complex, use large current charging; Surfactant replacement; The positive and negative pulse charging and so on, these methods to repair success rate is low, there are some negative effect. The approach taken now is a composite pulse repair method that can turn "irreversible" into "reversible" and basically does not cause any damage to the battery plates. This is a major breakthrough in lead-acid battery industry. The principle of pulse repair is more complicated.

First, any crystal has a resonant frequency after the molecular structure is determined, and this resonant frequency is related to the size of the crystal. The larger the size of the crystal is, the lower the resonant frequency. If charging adopts front steep pulse, using Fourier series to analyze frequency pulse can know can produce abundant harmonic components, the low frequency part of the large amplitude, high frequency part of the small amplitude. The energy obtained by such large lead sulfate crystals is large, and the energy obtained by crystallizing small lead sulfate is small, so that the amplitude of the formation of large lead sulfate crystal resonance is large, and it is easier to dissolve than the small lead sulfate crystal during positive pulse charging. It is called "crushing" the coarse crystals of lead sulfate. Appropriate control pulse current value to low current density of positive plate charge, basically do not form the positive plate of the damage. The pulse current value is appropriately controlled to charge the positive electrode plate with a small current density, and substantially no damage to the positive electrode plate is formed. For a sealed battery, the instantaneous charging voltage allows the oxygen generated by the electrode plate to be absorbed on the negative plate through the oxygen cycle, and the battery does not form a water loss. So this is a "lossless" fix that distinguishes it from other fixes.

How to activate the electric vehicle battery? The high-frequency positive and negative pulse generator is used to continuously generate high and low frequency conversion pulses for the battery, one of which can have the condition of dissolving large lead sulfate, and the other is the pulse disturbance, which destroys the condition that the large lead sulfate continues to grow, and this method overcomes The limitations of the previous repair technology, rapid, about 8-12 hours, high repair efficiency, low power consumption, will not cause the battery to lose water, the positive plate softens and change the original structure of the electrolyte, etc., for severely sulfided lead acid The battery repair effect is 3 to 4 times that of the past, and the repair rate is over 90%. The application of this technology reduces the amount of battery scrapped.

How to activate the electric vehicle battery?Try the following steps: 1. unscrew the plastic cover of each cell and check the internal liquid level. Not enough to fill up to the normal level. 2. Check the voltage of each cell with a multimeter, whether it is basically close, and whether there is reverse polarity, whether the total voltage is above 10.8V. If it is found that there are individual grid voltages that are low or reverse polarity, supplement or correct the polarity separately. 3, it is best to use the voltage and current adjustable, there is a charger for the voltage and current display. Connect the cable, turn on the power and observe the change of voltage and current. If it reaches 14V, there is still no charging current, then continue to increase the voltage to 16V. Wait for 4. As long as there is current, it means to start activation, and wait for the current to increase. Large, when the current is checked by one tenth of the capacity, such as 24 ampere when the battery exceeds 2.4 amps, the voltage reduction current is reduced to 2.4 amps. Wait until the voltage drops below 14V, and there is still 2.4AMPS of current, the activation is successful, and the charging phase is entered. 5, this long-term battery is generally charged for more than 14 hours, the maximum charging voltage is not more than 14.9V.

Correct use of the battery, charging method:

(1) It is right to use the battery for diligent use. Basically, it is charged after riding every day, but there is a problem here. If your battery can run for 30 kilometers, run 5 kilometers or 10 kilometers. It is charged, which may not be good for the battery, because when the battery is fully charged, there will be a gas overflow, and this gas is generated by the decomposition of water in the electrolyte, so that water loss occurs, frequently Charging, the battery loses more water, and the battery will quickly enter the expiration period. So the good way is that if you don't ride the electric car the next day, you'd better fill it up, but when you ride 5 kilometers or 10 kilometers, the next day is enough to run, it is best to wait. The next day, after riding, recharge, so that the battery's water loss will be reduced, and the battery life will be extended.

(2) In addition, for some batteries can run about 30 kilometers, but the daily riding is about 7 or 8 kilometers, it is best not to wait for the third or fourth day, the battery is completely used up and recharge, the battery power remaining half will be charged when it is not available, because the battery is stored when the battery is low, and it is prone to vulcanization.

(3) In addition, every one month, it is best to ride the battery once, that is, to ride the battery under pressure, deep discharge, and then charge the battery, which can also extend the battery service life.
