Most of the "electricity" as the power of the vehicle, are dependent on batteries, and the more expensive the vehicle, its battery comparison will be better, the more durable, and as a two-wheeled electric vehicle, its core advantage is cheap, so, its battery is not so durable, in general, the battery life carried on the battery life is about 2-4 years, and the life of an electric vehicle is about 5-8 years, which means that the owner will face the replacement of the battery.
When replacing the battery or buying an electric vehicle, you will face a choice, to configure what kind of battery to the electric vehicle, at present, the battery type is mainly lead-acid battery and lithium battery,Then, these 2 kinds of batteries, electric vehicle replacement battery which will be practical, cost-effective, small connoisseurs as electric vehicle practitioners, just share my answer.
What are the common lead-acid batteries and lithium batteries
Lead-acid batteries and lithium batteries, from the perspective of large categories, are 2 types, but in fact, the current electric vehicles are equipped with far more than 2 kinds of batteries, which is mainly, under the subdivision of lead-acid batteries and lithium batteries, there are many more subdivision battery types, including the following;
Lead-acid batteries: ordinary lead-acid batteries, graphene batteries, black gold batteries, these are lead-acid batteries, these 3 types of batteries, currently ranked in the market share of electric vehicles as ordinary lead-acid batteries> black gold batteries> graphene batteries.
Lithium batteries: ternary lithium batteries, lithium iron manganate batteries, lithium iron phosphate batteries, currently more used in electric vehicles are ternary lithium batteries, in the market share of electric vehicles ranked as ternary lithium batteries> lithium iron phosphate batteries > lithium iron manganate batteries.
Although electric vehicles also have hydrogen fuel cells, nickel hydride batteries, etc., but electric vehicles can currently choose, or the above lead-acid batteries and lithium batteries, for these 2 kinds of batteries should be how to choose, I give the following suggestions.
The pursuit of cost performance, choose lead-acid batteries
If you use electric vehicles, pay more attention to cost-effective, that is, more economical, there is no doubt that lead-acid batteries are the first choice, why do you say so, I said 3 advantages of lead-acid batteries, you will understand;
Advantage 1: Low price, 75% of the composition of lead-acid batteries is lead plates, and the price of lead metal is much cheaper than lithium metal, and the electrolyte of lead-acid batteries is the fusion of sulfuric acid and water, the electrolyte of lithium batteries is composed of lithium salts and organic solvents, the manufacturing process will be higher, therefore, the purchase price of lead-acid batteries is very low, basically about three-thirds of lithium batteries.
Advantage 2: Repairable, compared to lithium batteries are disposable batteries, broken can only be replaced, and lead-acid batteries, there is electrolyte water loss can be replenished, battery aging can be repaired by pulse technology, as a battery that can be repaired, it is easier to use cost-effective.
Advantage 3: Recyclable, lead-acid batteries after scrapping, it is not "waste", but has a high reuse value, therefore, many merchants will recycle or replace the old for new lead-acid batteries, its recycling price is about one-third of the new battery.
The above 3 points are enough to highlight the economic affordability of lead-acid batteries, so if the pursuit of battery cost performance, small connoisseurs strongly recommend the choice of lead-acid batteries, of course, lithium batteries as one of the mainstream batteries, it is not "useless".
Pursue the car experience, choose lithium batteries
Lithium battery as a rising star in the battery, can quickly become one of the main 2 kinds of batteries of electric vehicles in more than ten kinds of batteries, naturally has its advantages, small connoisseurs believe that if the use of electric vehicles to pursue a better car experience, choose lithium batteries, of which, there are 3 points, can support my views;
Point 1: good battery life, lithium battery is a high-density battery, its energy density is basically in 120-180WH/KG, while the energy density of lead-acid batteries is basically 40-70WH/KG, and energy density is an important indicator to determine endurance, therefore, the same capacity of the battery, the greater the density, the better the battery life.
Point 2: long life, lithium battery than lead-acid battery life is longer, this is a recognized fact in the industry, lead-acid battery life in about 2 to 3 years, lithium battery life in about 4 to 5 years, and let the battery life has such a gap, mainly 2 aspects of the reason, the first is lead-acid battery and lithium battery charge and discharge times are different, the second is lithium battery can be used with charge, will not damage the battery, and lead-acid battery charging is "very exquisite", the more easy to injure, the more durable it will be.
Point 3: good lightness, which is one of the core advantages of lithium batteries, electric vehicles want to design lighter, then, it must be equipped with lithium batteries, especially after the new national standard requires 55 kg of electric vehicles, lithium batteries are very popular.
There are many advantages of lithium batteries, but the above 3 points are enough to explain that electric vehicles equipped with lithium batteries, its car experience will be better, enjoy a lighter electric vehicle, a longer life battery, electric vehicle endurance is better, and charging will be faster, such an electric vehicle, the experience is naturally better than lead-acid batteries.
Considerations for choosing lead-acid batteries and lithium batteries
For the lead-acid of the battery, it can be understood that the lead-acid battery is more cost-effective, the lithium battery is more practical, then, when choosing these 2 types of batteries, what else needs to be paid attention to by the owner, and there needs to be a psychological preparation;
When choosing a lead-acid battery, you need to pay attention to its capacity, if you chase high endurance, my advice is not to choose a lead-acid battery, because, high-endurance electric vehicles naturally need batteries to have a larger capacity, to last more than 100 kilometers for example, it requires lead-acid batteries to have at least 32AH capacity, and 32AH If it is 72V voltage, its weight is about 60 kg, which is the weight of an electric bicycle, so in the case of weight, let the high endurance of electric vehicles greatly discounted, Can't play the endurance that this capacity should have.
When choosing a lithium battery, you need to pay attention to its safety, electric vehicles that can spontaneously combust, what is currently understood, are derived from lithium batteries, as a lithium active substance with flammable characteristics, if you want to choose it, you absolutely can not charge or park the electric vehicle upstairs, and you can not have bumps, below 0 ° C below the environment charging, otherwise it will increase the safety hazards of the battery, if you can't do this, try not to choose lithium batteries.
The above is about the electric vehicle in the replacement of batteries, lead-acid batteries and lithium batteries how to choose, as the electric vehicle industry insiders' suggestions, each kind of battery, since the existence of the advantages, and the choice of batteries is not practical, cost-effective, it depends on these advantages, is not what the owner wants, only match to the battery suitable for themselves, is more cost-effective, more practical.
So, when choosing a battery for an electric vehicle, will you choose a lithium battery or a lead-acid battery? Welcome to comment and exchange, pay attention to electric vehicle experts, and share electric vehicle related information and views every day.
