Electric Vehicle Battery Activation Method

Electric vehicles are divided into ac electric vehicles and dc electric vehicles. Generally speaking, the electric vehicle is the battery as the source of energy, through the controller, motor and other components, the electrical energy into mechanical energy movement, in order to control the size of the current change speed of the vehicle. The first electric car was built in 1834. It was driven by a dc motor. Today, electric cars have changed dramatically and come in many different types.

Generally, it is activated by high voltage charging, and the voltage is about twice as high as the standard charging voltage. The best charging current is pulse charging, and the charging current should not be larger than the battery capacity. Charging time cannot be too long, generally a few minutes to a dozen minutes. If it doesn't work, the battery is dead.

Factory batteries are activated, after use, do not need to be activated, normal charge.

Electric vehicles are generally valve control type sealed maintenance-free lead battery, in the first use of the battery charge is not special requirements, there is no activation. Before leaving the factory, the battery has become relatively complete, as long as the need to charge according to the situation of power consumption can be determined.

Please refer to the following charging method.

Under the condition of 100% power consumption, the general charging time will be in 8~10 hours, do not exceed 12 hours (it will have an impact on the battery life), of course, it is not recommended to use up the power every time, the general recommendation is to charge the power in about 70%, the charging time is generally in 6~8 hours.

If your trip is short, here are some Suggestions

It can be recharged once a week with daily consumption of 10%.

When the daily power consumption is at 20%, it can be charged once every three days.

It can be recharged once every two days when it USES 30 percent of its daily power.

When the daily power consumption is above 40%, it can be charged once a day, and the charging time under control is generally about 6 hours.

Hello my battery has 15 years, still have a little experience, damage of electric vehicle battery is usually one, the other will not bad, the so-called activated just deal with no damage to the battery, how do you get the damage only activate doesn't work, because it appeared a short circuit, open circuit, the plate fall off, no equipment may put the circuit welding, only we can manually open shell welding.

Electric car battery activation, now that is electric car battery repair, specific methods are:

A method of dissolving large lead sulphate crystals by negative resistance through high current charge.

In the experiment, it is found that the elimination of vulcanization can only obtain the temporary effect, and in the process of elimination of vulcanization will bring increased water loss and positive plate softening problem, serious damage to the battery life, not easy to use.

The negative pulse

This method has been applied for more than 30 years, the principle is to add negative pulse in the charging process, to reduce the temperature rise of the battery, but the repair effect of "vulcanization" is not obvious, the repair rate is 20%, the current use is more, is eliminated products, often about 1300 ~ 1600 yuan.

Addition of active agent

Using the chemical method to eliminate lead sulfate crystallization, not only the cost is high, increase the internal resistance of the battery, but also change the original structure of the electrolyte, the repair period is short, the repair rate is about 45%.

High-frequency pulse

The crystal of lead sulfate was converted back to reversible lead sulfate with fine crystal and high electrochemistry by pulse wave. It is better than the negative pulse. But because its repair time is long, need dozens of hours above, even a week's time, the efficiency is lower, to serious "sulfide" accumulator is repaired bad, but the technology is simple, have a lot of manufacturer reuse at present, the market price is about 2000 yuan.

Combined resonant 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 the 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. The disadvantage is that equipment technology is complex and the cost is high. Market price about -4 (independent 4 charge and release) for 2200-3800 yuan, -20 (independent 20 charge and release) for 8500-15000 yuan.

The principle and method of eliminating vulcanization by compound resonance method

Although we know that the main way to prevent battery vulcanization is to prevent the battery from not timely charging and over discharge, in practical use, this phenomenon is still often occurring. This has previously been considered "irreversible". The traditional method is more complex, using large current charging; Surfactant replacement; The repair success rate of these methods is low, and there is a certain negative effect. The current approach is a composite pulse repair method that turns "irreversible" into "reversible" and does virtually no damage to the battery pad. This is a major breakthrough in lead-acid batteries. The principle of pulse repair is more complicated. First of all, any crystal has a resonant frequency after the molecular structure is determined, and the resonant frequency depends on the size of the crystal. The larger the crystal size, the lower the resonant frequency. If the charging front adopts steep pulse, the frequency analysis with Fourier series can show that the pulse will produce rich harmonic components, and the low-frequency part has a large amplitude, while the high-frequency part has a small amplitude. In this way, the crystallization energy of lead sulfate is large, and that of small lead sulfate is small. As a result, the crystal resonance amplitude of lead sulfate is large, and it is easier to dissolve than that of small lead sulfate during positive pulse charging. This is called "crushing" large crystals of lead sulfate. By properly controlling the pulse current value and charging the positive plate with a small current density, the damage to the positive plate will not be formed basically. For sealed batteries, the instantaneous charging voltage enables the oxygen generated by the electrode plate to be absorbed on the negative electrode plate through oxygen circulation, so that the battery will not lose water. So this is a "loss-free" fix that differs from other fixes.

Using high frequency positive and negative pulse generator, battery constantly produce high and low frequency pulse, one may have the condition to dissolve the big lead sulfate, the second is pulse disturbance, destroyed 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, repair rate is above 90%, the application of this technology reduces the number of discarded batteries.
