Now the electric vehicle electricity is generally a long time ago, there are many car owners complain, the current battery life is very short, feel that they are replacing the refurbished battery, unlike the original battery installed when buying a car with four or five years. In fact, the battery you replace is not a refurbished battery, but the overall life of the battery produced now has declined, which is a few factors.
How long does the battery take to replace? How can I replace it with a durable and good quality battery? This is a question that many car owners should care about, and today Duobin will answer it for you from these aspects.
The service life of lead-acid batteries for electric vehicles varies
As long as it is a perennial electric vehicle people understand that in the past, from buying a car or replacing a new battery, the service life is generally 3 to 5 years, and there are relatively long uses, used to 5 to 6 years.
Just a few days ago, I changed three sets of batteries a day, of which two sets are 48V20Ah batteries used in electric motorcycles, one group uses JinChaowei batteries, which took 6 years, one group uses Shanshui batteries, which took 5 and a half years, and the other group is the 60V20Ah tianneng batteries used on freight tricycles, which took 5 years.
Usually when we replace the battery, it is rare to encounter three sets of batteries at the same time that 5 to 6 years of time, and occasionally encounter so many cars in 1 month, most vehicles are only used for 3 to 4 years, which is still an electric vehicle purchased or replaced a year ago to achieve this use time.
How long can an electric vehicle or replacement battery purchased after 18 years last? This topic has attracted constant controversy from all sides, and the answers given are different, some people say that the battery it replaces can be used for more than three years, some people say that his battery is only used for more than a year to replace, and some people say that his battery is only used for about two years to be replaced, and everyone feels that the current battery can only reach half of the previous effect.
Battery life varies from production materials
There are two key factors to determine the length of battery life, one is to protect the battery lead plate corrosion and prolong the service life. The second is the weight and thickness of the lead plate, which increases the number of cycles and durability of the lead plate.
The first point protects the cadmium element of the lead plate is prohibited,
Some industry insiders know that in the battery produced 18 years ago, there are increased battery life, an important element of the protection of lead plate corrosion "cadmium", is a harmful object, it plays a key factor in the life of a battery, before as long as the lead-acid battery is basically added to this substance, the battery will have a longer service life.
In order to better protect the environment, in 2012, the state issued the "Lead Battery Industry Access Conditions" clearly stipulates that lead-acid batteries with cadmium content higher than 0.002% or arsenic content higher than 0.1%, and their lead-containing parts production capacity, should be eliminated from December 31, 2013. After the promotion, the lead-acid battery produced after 18 years no longer contains cadmium substances.
This harmful substance has pollution to the environment, in order to protect the environment, it is strictly forbidden to add this harmful substance to the battery, 18 years later the management is more stringent, all lead-acid batteries have been prohibited from using this substance, the lead plate in the battery corrosion protection is reduced, the lead plate is prone to damage problems.
The second point is the reduction in the weight and thickness of the lead plate,
Many industry insiders found that the battery weight produced after 18 years has decreased year by year, we have found out the battery produced every year for 15 years after experimentation, and found that the battery weight of each year has declined after weighing, especially after the implementation of the new national standard, the battery weight produced by the car company has been significantly reduced, such as the battery of 20A as an example, the original single battery weight is about 7 kg, the current weight is about 6.3 kg, each piece is reduced by about 0.3 kg, and the lower the series classification level, the more the battery weight is reduced.
The battery is mainly the weight of the lead plate inside and the number of pages is reduced, the weight is reduced The thickness of the lead plate is thinner, there are the original 6 grids, and each cell is 6 pages down to 4 pages. The thickness of the lead plate becomes thinner and the corrosion resistance is reduced, and it is easy to damage the lead plate for a period of time, some batteries are used for several months or even a year, and the single battery drops the voltage capacity is low, the damage is more common, and the repair rate is also increased by 10% compared with the previous one.
The current general life of the battery
In our industry, whether it is repairing, or distributing cars, as well as wholesale battery practitioners are well aware of a truth, the battery service life after 18 years is generally about two years. Although the manufacturer did not give the answer to the use time of each type of battery standard, in the practice of more practitioners, combined with the conclusions drawn by the owners in the actual riding, this real result will be brought together.
Now there are many types of batteries in the promotion market, mainly famous brands such as Tianneng, Chaowei, Xupai, Jingqiu, etc., including boutique, secondary batteries that appear on the market, graphene, black gold batteries or long-distance running kings, longevity kings, and the service life is roughly different.
Because the battery does not contain harmful substances, the weight is reduced, the lead plate is thinner, and the service life of ordinary batteries is shortened more obviously, and the battery use now produced is 35% shorter than before. Like graphene, black gold batteries, or longevity kings, long-distance running and other endurance and life is OK, these types of batteries do not lose much weight.
How long does a normal battery last? In general, the performance is stable, and it can be used for 2 years. Like Chaowei and Tianneng batteries, the previous production including fine products and galaxy gold, the general life expectancy is more than 36 months, and the life of the current production is generally about 20 months, which is about two years. Now the production of card slots, the quality is worse, generally in about 17 months, generally reduced a lot, in the battery to understand the situation in this regard, we now buy the electric car and replace the battery can be used to how long life.
Although the current battery is not durable, but the price is half worse than before, long cyclists know this, such as the previous replacement of 60V20Ah battery price is about 700 yuan, now replace a group at about 400 yuan, the price reduction is also very large, we can also use the money saved to change another set of batteries, the overall use of the age is almost the same.
How long can graphene and black gold batteries last? According to the data given by the current multi-faceted test, it is generally about 30 months, that is to say, in two and a half to three years, and some heavier batteries can be used for more than three years.
Having said all this, some people will think that my battery took a longer time, can be used to 5 to 6 years, this kind of use of people is still very small, accounting for only 10%, it can be said that he used the process and the frequency of use is different and formed. The battery he installed or replaced is exactly this kind of battery just introduced to add heavy weight, this kind of in our actual measurement is also there, are produced 18 years ago, the life may be longer.
At present, the new national standard battery launched on the market is generally like this, and there are very few that can be used for two and a half years or more than three years. Today's article shares with you the service life of the battery before and now, and it is also clear when buying a car and changing the battery, and can install a battery with good quality and stable performance at the right price. Everyone can see clearly, you can type the three words "understood" in the comment area, give me support, remember to pay attention to me, like and forward the collection.
