Lithium batteries are not activated as previously nickel-hydrogen batteries, and the lithium battery is full of electricity. In addition, the lithium battery can be followed, and it is not necessary to use it as a nickel-hydrogen battery. The correct usage of the electric vehicle lithium battery is as follows: 1, the battery does not need "activation" lithium battery does not require the first three charge for more than 12 hours, the lithium battery has no memory.

2. Battery charging uses the charger specified by the manufacturer to charge, pay attention to whether the charger model matches the battery model when charging. 3.

Avoid high-temperature charging lithium batteries Do not charge in a temperature of more than 40 °, high temperature will reduce battery capacity. 4, timely charging to the lithium battery as much as possible, avoiding the battery will then charge each time, so that it can greatly improve the battery life. 5.

Store for a long time without using the battery, the battery should be disconnected and the battery is added to the battery at intervals, avoiding battery self-discharge, or protecting the battery. Lithium battery is afraid of overcharge more excessive discharge. However, the lithium battery has no memory effect, and it can be followed.

Don't charge the electricity to charge, so it is easy to over-discharge the damage battery; don't discharge the big current, it is best to use the foot to help, avoid the battery life, affect battery life. The same reason, should avoid exceeding the load specified by the specification. The charger is generally protected, which generally does not cause overcharge, but at night, the power grid load is very light, the voltage is high, easy to exceed the charger setting with self-stop voltage, and will continue charging the battery, This is easy to cause overcharge, when the night is deep, the charger should be pulled down.

Hello! The correct usage of the electric vehicle lithium battery is as follows: 1, the battery does not need "activation" The lithium battery used by the company does not require the first three times to charge more than 12 hours. 2. Battery charging uses the charger specified by the manufacturer to charge, pay attention to whether the charger model matches the battery model when charging.

3. Avoid high-temperature charging lithium batteries Do not charge in a temperature of more than 40 °, high temperature will reduce battery capacity. 4, timely charging to the lithium battery as much as possible, avoiding the battery will then charge each time, so that it can greatly improve the battery life.

5. Store for a long time without using the battery, the battery should be disconnected and the battery is added to the battery at intervals, avoiding battery self-discharge, or protecting the battery. Electric vehicle battery is activated, and now it is the electric vehicle battery repair, the specific method is:? Method for charging the large current crystal to dissolve the dissolution.

In the experiment, this eliminating vulcanization can only obtain temporary effects, and will bring weight loss and positive electrode softening problems during the elimination of vulcanization, and cause serious damage to battery life, it is not easy to adopt. • Negative pulse This method has been applied so far, the principle is to add negative pulses during the charging process, and the temperature rise of the battery is reduced, but the repair effect of "vulcanization" is not obvious, its repair rate is 20%, currently There are more, which are eliminated products, and the time price is approximately 1300 to 1600 yuan. • Adding a chemical method, eliminating lead crystals of sulfate, not only high cost, increasing the internal resistance, and also changed the original structure of the electrolyte, the repair period after repair, its repair rate is about 45%.

• High-frequency pulse uses pulse wave to re-convert the lead crystals of sulfuric acid into a small crystal, high electrochemical, so that it can normally participate in the chemical reaction of charge and discharge, and the repair rate is about 60%. Negative pulse effect is good. However, due to its long repair time, it takes ten hours or more, and the efficiency is low, and the battery is low, but the battery is not good, but the technology is simple, there are many manufacturers to use, the market price is about 2,000 yuan.

• Combined resonant pulse reasonable control repair pulse front edge At the time, the repair efficiency is high, the battery is small, which greatly reduces the contamination of the lead-acid battery to the environment, and the battery life is prolonged, and the huge cost of the user is replaced by replacing the battery. Therefore, the prospect is broad. The disadvantage is that the equipment technology is complex, high cost, and the pulse frontier control and resonance technology requires high.

The market price is approximately -4 (independent 4 charge) is 2200-3800 yuan, -20 type (independent 20 charge) is 8500-15000 yuan. Composite resonance method eliminates the principle and method of vulcanization, although we know that the main method of preventing battery vulcanization is to prevent battery failure and over-discharge, but in actual use, this phenomenon often occurs. This happened previous situation was considered "irreversible".

The traditional treatment method is more complicated, using large current charging; active agent replacement; positive and negative pulse charging, etc., these methods have a low success rate, there is a certain negative effect. The method taken now is the method of composite pulse repair, which can turn "irreversible" into "reversible", and basically do not have any damage to the battery polar plate.

This is a major breakthrough in lead-acid batteries. The principle of pulse repair is more complicated. First, any crystal has a resonant frequency after the molecular structure determination, and this resonant frequency is related to the size of the crystal.

The larger the size of the crystal, the lower the resonant frequency. If the charging is used in the steep pulse, the frequency analysis can be used to use Fourier fraction, and the pulse will produce a rich harmonic component, and the low frequency part is large, and the high frequency part is small. Thus, the energy of lead crystals of large sulfate is large, the energy of lead crystals of small sulfate is small, thereby forming a large amplitude of the lead crystalline resonance, and is easily dissolved during the positive pulse charge.

Coarse thickened sulfate crystallization of "crushing". Appropriate control of the pulse current value, charging the positive electrode plate with a smaller current density, substantially not forming damage to the positive plate plate. For sealing batteries, the instantaneous charging voltage causes oxygen generated by the electrode plate to be absorbed on the negative plate by oxygen circulation, and the battery will not form water.

So this is a "no loss" repair that distinguishes with other repairs. With high frequency positive and negative pulse generators, the battery is constantly producing high and low variable frequency pulses, which can have conditions for dissolving primary sulfate, and the second is pulsed disturbance, destroying the conditions of continuous growth of large thirates, which. The limitations of previous repair technologies have rapidity, about 8-12 hours, high repair efficiency, small power consumption, no battery loss, positive electrode plate softening, and altering electrolytic solution, lead-acid The battery repair effect is 3 to 4 times the past, and the repair rate reaches 90%.

The application of this technology reduces the number of batteries.
