How to solve the vulcanization problem of electric vehicle batteries

Regular maintenance: Regularly go to a professional maintenance point to repair the battery every three months, and replenish water in time. These methods are simple and easy to implement, and the economic cost is very low, but it is difficult to strictly follow them. Therefore, most of them use special equipment for sulfur removal and maintenance. The methods are as follows:

1. Use desktop rapid de-sulfurization equipment

The working principle of the desktop rapid desulfurization equipment is high-voltage and high-current pulse charging to eliminate sulfuration through negative resistance breakdown. This method is fast and effective, and can temporarily eliminate vulcanization. However, high voltage and high current can remove sulfur and active substances, which will bring serious water loss and softening of positive plates in the elimination of vulcanization. It will cause fatal damage to the battery, and the battery that has been desulphurized twice by this type of equipment will basically be scrapped. At present, professional battery maintenance shop owners in the market have understood the harm of this method. Therefore, pulse discharge desulfurization equipment has appeared. In fact, the fundamental principle has not changed, but it has changed from constant high voltage and constant current to instantaneous The peak high voltage will still damage the active material of the plate.

2. Choose a sulphur-removing charger

At present, there are three working principles of sulfur-removing chargers. One is similar to the working principle of desktop fast sulfur-removing equipment. It uses high-voltage and high-current pulse charging to remove sulfur through negative resistance breakdown. Longevity constitutes a fatal injury, which has been denied by the market. The second is to use the charging and discharging pulse of the fast pulse leading edge, and use the instantaneous peak value to interfere with the vulcanization of the battery during the charging process. The other is to periodically use a 10% to 20% overcharge method to restore the lead sulfate crystals of the battery.

3. Use online lead-acid battery life extension device

The on-line lead-acid battery generator is connected in parallel with the battery to prevent and eliminate vulcanization 24 hours a day. This method is relatively slow to repair, and the repair time is relatively long, often more than 120 hours, but whether it is charging or discharging, it can prevent and eliminate vulcanization, and the repair effect is very good. Because of the use of low voltage and low current, the generator will not have a strong impact on the battery plate, resulting in water loss and softening. This is a maintenance method that users can persevere with one investment, especially for new batteries with better quality. Extends the battery life by 2~5 times, and once invested, it can always accompany the electric automatic vehicle. The next time the battery is replaced, the life extension device can continue to be used, which can save a lot of economic costs for users.

Taking this approach makes a lot of sense. The first is to bring real economic benefits to users and reduce the troubles of users. The second is to improve the reputation of the car factory and provide conditions for expanding production. Third, it solves the problem of battery quality assurance for electric vehicle dealers, reduces complaints, improves credibility, and increases profits. Fourth, it can greatly reduce the cost of claim settlement for battery manufacturers. Fifth, improve the image of electric bicycles and expand the development of the overall market of electric bicycles. Sixth, improving the utilization rate of the battery is conducive to environmental protection.

The advantages mentioned above are actually just one sentence, that is, the benefits of extending the battery life. In fact, the actual use is not as good as the above paragraph touted. Some people I know have used it and said that it has no effect, but now they don't use it, and they say that it can prolong the lifespan by 2 to 5 times! General batteries, pay attention to the usage and precautions, generally can be used for one and a half years, and the better ones can be used for two years or more. This is used on electric vehicles, not as a backup power source for lighting. I have heard that electric vehicles use three-year batteries, but never 10 years. Unless you charge every day, you only need to run a kilometer or two every day.

To put it bluntly, many extenders are only a short-term high-current discharge circuit. It has a certain effect on solving the vulcanization of the battery, but in its view, as long as the extender is installed, the vulcanization of the battery can be completely solved, which is impossible. Because the root cause of the vulcanization of the battery is the problem of use and charging, the most fundamental way to solve the vulcanization of the battery is to prevent the vulcanization, plus regular maintenance. For example, for individuals, we only need to pay attention to the methods and precautions used, and then use corresponding methods to solve problems when we find them.
