Some secrets of electric car battery renovation

As an environmentally-friendly vehicle, electric vehicles are rapidly becoming popular with their advantages of convenient travel and low price, making them the first choice for many citizens. However, some friends often say electric vehicles always "anchor" due to lack of power on the way to work. After several years, the car feels that it is not necessary to spend a lot of money to change the high-end battery, so they bought a piece at a nearby repair shop. The cheap battery, it took a long time to find that it is old, and suspected that it bought a refurbished battery.

Everyone noticed that, in our streets and alleys, we often see the "electric vehicle battery recycling" booth, called to recycle used batteries then you know where these recycled electric car batteries go?

That's right, it's very likely that like my friend bought, the used batteries were made into refurbished batteries, which were recycled back by the manufacturer, then processed and sold to customers with the new battery price.

It is understood that the battery refurbishment of electric vehicles actually has a certain effect, but the refurbishment effect is certainly not as good as the new raw materials. The general battery life is that the complete rushing discharge reaches 450 times, and its metabolism is completed.

Refurbished batteries have certain technology, and the general manufacturers have this kind of strength. The so-called repair on the market is just a fur, and the fundamental problem cannot be solved. The main raw material of the battery is lead metal, which is harmful to the human body. It is best to have less professional knowledge.

According to industry insiders, there are three types of electric vehicle batteries sold in the market: lead-acid batteries, nickel batteries and lithium batteries. Among them, lead-acid batteries with lower cost are most popular, because the used batteries will cause environmental problems, and special the treatment is generally recovered by the battery manufacturer, the electrolyte is poured off, the lead therein is extracted, and a new battery is produced by using the same.

The master of electric vehicle maintenance work said, "The electrolyte of the battery is toxic. If it is handled by itself, it will not only corrode the skin, but also cause serious environmental pollution."

Think about it, how terrible it is not only harmful to our human body, but also has a serious impact on our living environment.

So when it comes to this, how do you tell if the battery is original or refurbished?

In order to avoid the problems of friends riding electric cars, let’s take a look at it today.

How to distinguish between original and refurbished batteries

First, the appearance of the brand new battery is generally smooth and clean, the surface of the refurbished battery will be polished, because the original mark should be eliminated, repainted and marked with a date, if you look carefully, you can see the mark that was originally polished off.

Second, there will be solder residue in the wiring terminal block of the refurbished battery. Even if it is polished, it can be seen that there is trace of grinding. Although some refurbished batteries will replace the terminals, the color of the positive and negative marks is unevenly painted. At first glance, it is a refilled battery.

Third, there will be a date on the battery pack to check whether the date on the package matches the date on the battery and whether it has been modified.

Fourth, identity, under normal circumstances, the regular battery is shipped with the certificate and warranty card. When the product has problems, the warranty card is a valid certificate for the merchant to solve. If there is no warranty card, then it is very good. It may be a refurbished battery. I hope that when you replace the new battery, pay attention to it and avoid buying refurbished batteries to avoid unnecessary losses.

Summary and supplement the following points

The refurbished battery will be the same as the manufacturer's method. After polishing, waxing, coating, and date, we can distinguish it.

The battery will be left with a lot of scratches after being polished, and the QR code will be blurred after the coating.

In addition to these can also look at the last few letters after the date, turnover maintenance will appear behind the Cs, ZZ words, each battery manufacturer is almost the same, this method to see the kind of turnover maintenance battery, after polishing a few words of non-sales Look at a standard.

Finally, please pay more attention to the battery date when changing the battery, and change the battery as much as possible to the bigger store, do not rush to change the turnover or maintenance of the battery.

Ok, I understand that here, I believe that everyone can solve this situation.
