How to activate the lithium battery in electric vehicle

The lithium battery is unlike previous Ni-Mh battery activation. Lithium battery can be used normally after it is full of electricity. In addition, the lithium battery can be used while charging, unlike Ni-Mh batteries, which must charge after running out of electricity.

The correct ways of using the electric lithium battery are as follows:

1, the battery does not need to "activate"

Lithium batteries don't need the first three time charge more than 12 hours, lithium battery no memory.

2, the battery

When using the charger manufacturers specified charging, charging and pay attention to whether the charger model matches the battery model.

3, avoid high temperature

Lithium-ion batteries do not charge under the environment of temperature more than 40 °, high temperature can make the battery capacity decline.

4, timely charge

For lithium battery increases with the increasing use of charging, as far as possible to avoid the battery recharging after under voltage, every time so that we can greatly improve the battery life.5, store

Should be when do not use the battery for a long time not connected, the battery and the interval and a period of time to add some power, avoid the battery self-discharge, or power battery protection board.

Fear of excessive lithium-ion batteries charging more afraid of excessive discharge. But lithium batteries have no memory effect, can be in charge. Don't completely run out before charging, so easy to damage excessive discharge the battery; Don't large current discharge, where the steep, it is best to pedal power, to avoid the battery current is too large, affect the battery life. In the same way, should avoid to load more than specification. Charger usually have full protection, generally will not result in a charge, but the night when the network load is light, high voltage rises, easily more than set full automatic stop voltage charger, and will continue to charge the battery, the cause of charging, night, the charger should go down.

Electric vehicle battery activation, now that the electric car battery repaired, specific methods are:

?Use large current charging, make big lead sulfate crystals to produce negative wear to dissolve method.

Experiments found that the effect of eliminating sulphide can only get a temporary, and will lead to increased water loss and are in the process of removing sulfide plate softening problem, cause serious damage to the battery life, not easy to use.

The negative pulse

Principle of this method has been more than 30 years history, is in the process of charging to join the negative pulse, has the function to reduce the battery temperature rise, but to "cure" repair effect is not obvious, the repair rate is 20%, currently USES more, belong to eliminate product, often the price of about 1300 ~ 1600 yuan.

Adding surfactant

With chemical method, eliminate lead sulfate crystallization, high cost, not only increase the battery internal resistance, and also changed the original structure of the electrolyte, the repaired shorter lifespan, the repair rate is about 45%.

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.

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 from the huge cost, replace the battery so broad prospects. 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.

Composite resonance method to eliminate the principle and method of sulfide

Although 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. Now composite pulse method is to repair, the method of "irreversible" could be turned into "reversible", and basically the battery plate is without any damage. This is a major breakthrough in lead-acid battery industry. The principle of pulse repair is more complicated. First, any crystal after molecular structure resonance frequency, and the resonant frequency is related to the size of the crystals. The greater the size of crystal, the lower the resonant frequency is. 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. Such big lead sulfate crystallization to obtain energy, small lead sulfate crystallization to obtain energy, thus forming a lead sulfate crystallization resonance amplitude is large, during the pulse charging is easier than small lead sulfate crystals dissolve. Is the so-called "break" the lead sulfate crystal. Appropriate control pulse current value to low current density of positive plate charge, basically do not form the positive plate of the damage. For sealed battery, the charging voltage makes the plates of the moment produced by oxygen or oxygen cycle on the negative plate is absorbed, battery also won't form water loss. So this is a kind of difference with other repair method of "no damage" repair.

Using high frequency positive and negative pulse generator, and constantly produce high and low frequency pulse to the battery. Firstly, it may have the condition to dissolve the big lead sulfate. Secondly, it is pulse disturbance, which can destroy the condition of big lead sulfate continue to grow. This method overcome the limitations of the previous repair technology, has the quickness, about 8 to 12 hours, repair of high efficiency, less consumption, does not cause the battery water loss, positive plate softening and the advantages of changing the original structure of electrolyte. Lead-acid battery repair effect of severe sulfide is 3 ~ 4 times in the past, and its repair rate is above 90%. The application of this technology reduces the number of discarded batteries.
