Electric car is a very convenient and low-cost transportation, however, many owners complain that the durability of electric car battery is very poor, and need to replace the battery often. In addition to overuse,Battery recycling this may also be due to the choice of an inappropriate battery. EV batteries also come in different quality grades, so their lifespan can vary greatly.

The batteries used in electric cars include lithium, lead acid and graphene batteries, and each of them has a different lifespan. So, do you know why they are different? It has to do with two main things.

The first is the physical lifespan of the battery, which means that it is related to the quality of the battery, the way it is charged, the way it is ridden, the weight it carries, and the weather when using an electric bike.cylindrical cell assembly machine Simply put, the more attention you pay to maintenance, the longer the battery will last.

Next is the life of the battery in terms of the number of cycles of charging and discharging. All batteries need to be set at the factory for the number of times they can be charged and discharged in cycles,battery making machine and different batteries vary greatly in their performance in this regard, which is also determined by the inherent differences between battery types.

These two factors are at the heart of how long a battery lasts. Since maintenance varies from person to person, we will judge the length of battery life primarily based on the second number of cycles of charging and discharging. Next, I will rank the mainstream types of batteries that are replaced in electric vehicles so that you can understand their approximate lifespan so that you can choose a more durable battery.

The number one life expectancy is lithium iron phosphate/lithium ternary batteries. The lithium batteries we often talk about mainly include lithium iron phosphate and lithium ternary batteries. These two types of batteries are excellent in terms of the number of cycles of charging and discharging, lithium ternary batteries have no less than 800 cycles of charging and discharging, while lithium iron phosphate batteries have no less than 2000 cycles.

To electric vehicles every two days to complete a cycle of charging and discharging calculations, the life of lithium ternary batteries is about 4.5 years, while the service life of lithium iron phosphate batteries can even reach 10 years. It can be said that lithium batteries are the best in terms of life expectancy. However, it should be noted that lithium batteries are more expensive and have the possibility of bursting into flames.

Second on the longevity list are graphene batteries/black gold batteries. Although some people think that graphene batteries or black gold batteries are "graphene elements" as a gimmick to increase the price of lead-acid batteries, but from the actual use of the situation, they are indeed better than ordinary lead-acid batteries in the cycle charge and discharge number of times, generally can reach 600 to 1500 times of the cycle charge and discharge number.

Ranked third in longevity are ordinary lead-acid batteries. Lead-acid batteries were one of the first types to be popularized in electric vehicles, and they are now also divided into different quality levels. Ordinary lead-acid batteries are basic batteries, manufactured with virgin lead, and their cycle charge/discharge times are generally 300~500 times. Calculated on the basis of completing one cycle every two days, the service life of an ordinary lead-acid battery is about 2.2 years.

As can be seen, the life of lead-acid batteries is not very long, but the advantage of these batteries is that they are very cheap, only about one-third of lithium batteries and about two-thirds of graphene batteries. In addition, lead-acid batteries have a high recycling value, even if scrapped can be traded in for a higher value, so it is a very cost-effective type of battery.

Ranked fourth in longevity is the boutique battery. As we mentioned earlier, lead-acid batteries can be recycled, and the lead-acid batteries manufactured by recycling are fine batteries. Although there is no difference between these batteries in terms of after-sales service, factory inspection standards and virgin lead batteries, they have a relatively shorter lifespan.

The number of cycles of charge and discharge given by boutique batteries is generally 300 to 500 times, but it is commonly around 300 times. Based on completing one cycle every two days, the basic service life of a boutique battery is less than 2 years. However, it has the advantage of being cheaper as the lowest end of the lead acid batteries sold.

Ranking fifth in longevity is the aftermarket category of batteries. All four of these are sold batteries, but there is another category of batteries that are still circulating more in the market even though the manufacturers define them as not for sale, and that is the aftermarket category of batteries. These batteries are usually defective batteries whose existence is to solve some after-sales service problems.

As batteries that are not for sale to the public, aftermarket batteries are not entitled to manufacturer's warranty and their lifespan is relatively short. Generally speaking, there is no problem after half a year of use, but after a year of use the range decreases and cannot be used normally.

They are employing a "biode," which combines the properties of an anode and a cathode, to create the first freestanding alternating current (AC) battery in history. Comparing AC batteries to normal batteries, which use direct current (DC), reveals that the former are 30% more compact, safer, and more efficient.
