Is the after sales battery of an electric vehicle good Can the after sales maintenance battery of an

Members of China Electric Vehicle Alliance: The after-sales batteries of electric vehicles are the original car with batteries, which can be used for more than one year under normal circumstances, but if you use brand-name batteries such as: Tianneng, Chaowei, Shanshui batteries, it will be more than half a year longer than the original car with batteries, but it still needs to be maintained.

The correct way to use the consumer battery Some consumers use the battery improperly, one is to charge for a long time, thinking that the longer the charge, the more power will be sufficient; the second is to lose power for a long time, and it will not be charged until it can't run; the third is to charge when the temperature is too high or too low; Fourth, do not pay attention to the regular inspection and maintenance of the battery. How to charge and discharge correctly The correct use method can play a role in extending the life of the battery to a certain extent. Now I will give a brief introduction to the correct way to use it:

1. It is not advisable to charge the battery after riding The life of the battery is determined by the number of charging and discharging cycles, and the more times it is charged and discharged, the faster the life will be reduced. Therefore, you should not just ride an electric car and then charge it, but should master it when the maximum mileage of the battery is 60%-70%. 2. The charging time should not be too long Many electric vehicle users believe that the longer the charging time, the more battery power will be sufficient.

This is very wrong. The charging time is generally extended within one hour after the charger is changed. Long-term overcharging can easily lead to battery deformation, water loss and other phenomena.

Thus directly jeopardizing battery life. (The first three charging times of the new car are: 12-14 hours, and the subsequent charging time is:.)

6-8 hours) Third, it is best to use a smart socket Many electric vehicle users go home from work to charge, and cut off the power when they go to work the next day, in fact, most chargers cannot 100% guarantee that the battery will automatically power off when it is full. The best way is to buy a smart socket and set the time when charging, so that you can solve the problem of resting at night. Fourth, it is strictly forbidden to run at a loss of power Some users have been charging the electric car until it can't be ridden, which seriously harms the battery performance.

Multiple deep discharges can drastically reduce battery life. If the power is not sufficient on the way, it is best to pedal the assist in advance to avoid deep discharge. 5. Do not charge when the temperature is too high or too low.

The battery itself will generate a small amount of heat during the charging process, and charging at too high a temperature will increase the temperature of the bottle and damage the performance of the battery. The temperature is too low. The battery has poor receptivity, weakened activity, insufficient battery power, increased number of charge and discharge, and shortened battery life.

First of all, you have to know one thing, the battery of the electric car is guaranteed for one year from the date of purchase, the battery is broken within half a year, the battery is replaced for more than half a year, and the battery is replaced for more than half a year. Maintaining the battery is to send your group of broken batteries back to the manufacturer, and the manufacturer will pick out the broken batteries, and then use the good batteries to re-assemble them, and use them as maintenance batteries! Of course, the effect of maintaining the battery is not as good as the new battery, but this is also a matter of no way, and this is also the "unspoken rule" of the battery line!

Hahaha......If you come across a good maintenance battery, there is no problem in using it for about a year!

Of course, the after-sales battery of electric vehicles is not as good as the new battery, or what is the after-sales battery, the after-sales class A battery can be used for about 8 months, class B 5 months, class C 3 months, some battery factories part of the ABC class, about half a year or so Electric vehicle battery exchange society welcomes you to join, if you are satisfied with the group, please give the group ++ points, thank you.

Buy a brand electric car, such as a new day or something. Generally 2 years is no problem.

Hello. Friends can be replaced, electric vehicle after-sales maintenance batteries can be replaced, and they can be replaced within the warranty period. Extension:

The principle of one-year replacement of electric vehicle battery: from the day of buying the car, or the day of purchasing the battery, due to the damage of the battery due to quality problems during normal use within one year, the battery can no longer be used, you can go to the merchant after-sales store for replacement, of course, it is not to replace the battery if you want to replace it, it should be replaced according to the provisions of the merchant's after-sales service, and the battery is generally required to be charged and discharged tested. Under standard conditions, the battery capacity is less than 60% at a temperature of 25 degrees Celsius, and the battery can be replaced.

Hope it helps.

It works, but the performance is generally not as good as a new battery

Generally, it can be divided into new batteries, turnover batteries, and maintenance batteries, and turnover batteries and maintenance batteries are usually called aftermarket batteries.

In general, a new battery outperforms a turnaround battery, which outperforms a maintenance battery. Due to the gap between the two companies, some unscrupulous businesses will use the after-sales battery as a new battery to seek the greatest benefits, which is also one of the important reasons why many users replace the new battery for a short time.

Distinguish between the original battery of the electric vehicle and the aftermarket battery

First, from the perspective of the outer packaging.

First of all, there are two types of aftermarket batteries, namely turnover batteries and maintenance batteries, and the difference between these two types of batteries is that the return time is different.

Generally speaking, the recycled battery will be packaged in blue and the box will have the word turnover, while the maintenance battery will be packaged in green or yellow with the word maintenance in the box. The original battery is generally packaged in other colors such as white and red. Therefore, when the user replaces the battery, he can judge whether the battery is the original battery or the aftermarket battery according to the packaging.

Second, from the point of view of the date of production.

Secondly, users can check the production date of the battery, generally the original battery date is clear, there are no extra traces, and the aftermarket batteries have obvious grinding marks, and some batteries even have handwritten dates.

In addition, it should be noted here that generally after-sales batteries will be printed with the words "after-sales special", while the original batteries do not have these words. Therefore, users can judge whether the battery is original or not by the two characteristics of the production date and "aftermarket use".

Third, from the point of view of documents.

In addition, the original batteries have certificates, anti-counterfeiting codes and other certificates, and the parameters and information of the group of batteries can be queried through the official website, while after-sales batteries generally do not have these certificates. Therefore, users can judge whether the selected battery is an original battery or an aftermarket battery by querying various documents.

Do you understand the warranty period of electric vehicle battery? Tell you quietly, it's not actually a year.

It's a year to ask.

But what if he doesn't give it to him?

You often don't use it.

The battery loses power.

It's only been five months since I asked the question.

So he is what you give back to you.

He won't change it for you.

Generally, if you don't use it for a month, there will be a power loss.

Naturally, batteries don't work.

Thank you for your question!

Generally, the commitment of electric vehicle manufacturers and battery manufacturers is that the battery pack will be used for one year, and the individual commitment package will be used for one and a half or two years. However, this package refers to the fact that when you go to replace the battery, you will only be given a usable battery, not a new battery, which is generally a battery that has been repaired and can be used for a short time.

The national warranty does not mean that you can go to a random store and change the battery for free. You can only go to the store designated by the manufacturer to change it.

Of course, you can also ask the store to replace only one battery, but the other batteries must be good, and the battery must be close to the performance of the battery that has not been replaced, so as to ensure that you can use it for a longer time after changing the battery.

Your battery must be broken, it's hard to say whether the charger is good or not, let's see if you use it after changing the battery.

Electric vehicle batteries are generally lead-acid batteries, and the warranty period given by battery manufacturers to dealers is generally 15 months, before 8 and after 7, due to the quality of the battery itself, the new battery within 8 months, 9 11 months for the turnover battery, and 12 for 15 months for the maintenance battery. At present, the shelf life of users in the secondary market is generally one year, because there is a certain cycle from the factory to the dealership and then to the repair shop.

If the appearance of the battery is damaged due to human reasons, including the bulging of the battery that has been detected as a non-battery quality problem, it can only be downgraded and replaced with a turnover battery.

1 The mismatch of charger parameters causes thermal runaway during charging and causes the battery to swell, which is artificially caused.

2. The quality problems of the pole group itself inside the battery, such as the micro-short circuit of the pole group and the lack of acid, will also cause the thermal runaway of the battery to bulge, which is the quality problem of the battery itself.

If the temperature is not abnormally high to hot (a slight heat is normal), it can be concluded that it is not an internal problem of the battery pole group, but caused by the mismatch of the charger parameters, it is a man-made reason, on the contrary, it is a quality problem of the battery itself.

Restoring electric vehicle batteries is a very professional profession, which requires a mastery of the internal composition of the battery and the principle of the electric inner battery. Not all.

The batteries are worth refurbishing, and generally if the battery life can be extended by refilling the liquid or charging cycle, it can be repaired, and there is no need to do other things like no voltage and no current.

When the appearance of the battery is not damaged, swollen, and there are no signs of short circuit or open circuit, the following methods can be taken to try to repair the battery

1. Use positive and negative pulses to depolarize the battery, and then completely discharge, so that three cycles, if the capacity has signs of recovery, you can cycle several more times to achieve better repair effect.

2. Add water for repair, add deionized water or purified water when adding water, do not add tap water, it will cause the problem of large battery self-discharge. Here's how:

1) Discharge the battery completely first, because the acid density inside the battery is basically below after discharge;

2) Take out the cover piece, and then remove the safety valve, pay attention to keep it, do not dirty the safety valve, for later use;

3) Add water, generally the water added in a single grid of 12Ah battery is 8 10g, and the water added in a single grid of 20Ah battery is about 15g;

4) Let stand for about an hour, and install the safety valve and cover sheet;

5) Charge, fully charge, and then fully discharge, and so on three times.

Measure and copy 4 batteries to the protection state, see which battery voltage is the lowest compared with other sections, remove this battery, charge it with a 12 volt charger alone, charge it for about 10 hours according to 2 amps, and then discharge it to 10 volts with a 12 volt 25 watt bulb after it is fully charged, calculate the discharge time, and see if the battery can be discharged for more than 6 hours; Do a few more cycles to see if you improve. If the discharge time is too short, this section needs to be replaced. Before replacement, you can also do some experiments, such as adding distilled water and sulfuric acid to see if it can be improved.

The other sections can also be discharged and then fully charged after a single section, and repeat a few times to actually calculate the power of these sections. The 20 Ah battery should be able to discharge for 10 hours according to the discharge current of a single section 2 amps.

You can't repair it yourself.,If you can repair it yourself.,Then do you still use a car repair master?。。。

It should be possible.,You can look for the manual.。。。

No, you have to find a professional.
