What kind of battery is used for general electric vehicle batteries, is it better to use lead acid b

Generally, electric vehicle batteries are used in lead-acid batteries, and a small number of smaller electric vehicles use lithium batteries. The sales of lead-acid batteries are much higher than the sales of lithium batteries, and the use is more common.

Each has its own merits. The comparison of batteries used in battery carts is as follows:

Lithium battery - lead-acid battery.

1.Rechargeable battery.

2.Cycle life (500 times - 400 times) 3Specific energy (>150w·h kg - 40w·h kg) 4Charging time (2 4h - 6 8h).

5.Discharge energy efficiency (lithium battery discharge efficiency can be greater than 90% - lead-acid battery discharge efficiency is more than 80%)

6.**(Higher – Lower).

7.Volume (small – large).

8.Weight (light weight – heavy weight).

9.Cruising range (for batteries of the same specification, because lithium batteries are composed of multiple batteries, although the single discharge efficiency is high, the overall efficiency is reduced, so the mileage of the two batteries is comparable).

10.Pollution in production and use (pollution in production - there is a large amount of lead and acid in lead-acid batteries, which will pollute the environment if not properly disposed of after disposal).

11.Discharge (susceptible to damage from deep discharges and short circuits – susceptible to damage from deep discharges)12Charging & Maintenance (Complex, High Maintenance – Simple, Low Maintenance).

Generally, electric vehicle batteries mostly use lead-acid batteries, and light electric vehicles use lithium batteries, lithium batteries are light in weight and have a long life, but they are more expensive. With the advancement of technology, lithium iron phosphate batteries have a tendency to replace lead-acid batteries.

In terms of energy density and power, it is definitely a lithium battery, with higher energy and a large output power in the same volume. But it's not as safe as lead-acid batteries. In addition, lithium batteries are larger than lead-acid batteries. If you want to use it for a long time, lithium batteries are still recommended.

Lead-acid batteries are bulky and have a small capacity, but they are cheap, while lithium batteries are the opposite.

As for which one is better, of course it is a lithium battery that is good, as long as you don't care about the cost and **.

Regarding electric vehicle batteries, is it better to use lead-acid batteries or lithium batteries? Listen to what the maintenance master has to say!

Lead-acid batteries are still used, because at present, lead-acid batteries are more stable and safer, and are much lower than lithium batteries, which are more acceptable to users.

The difference between lead-acid battery and lithium battery.

First of all, from the cost level, lead-acid batteries have more advantages. Because the ** of general lithium batteries is 2 to 3 times that of lead-acid batteries, this means that if you choose a new lithium battery, the cost will increase greatly, and lead-acid batteries are relatively economical. In addition, lithium batteries are not easy to be dismantled and reused, and the cost is higher.

Secondly, from the perspective of manufacturing requirements, lead-acid batteries have more advantages. Because the manufacturing process of lithium batteries is more demanding, it is relatively difficult to manufacture. The lead-acid battery technology is relatively mature and relatively easy to manufacture.

Furthermore, from the perspective of charging performance, lithium batteries are more advantageous. Because lithium batteries have a higher average voltage and energy density than lead-acid batteries, this means that lithium-ion batteries have a larger capacity and a longer range than lead-acid batteries.

In addition, from the perspective of lightness, lithium batteries are also more advantageous. Generally speaking, the weight of lithium batteries is only one-third of that of lead-acid batteries for batteries of the same size, which means that electric vehicles equipped with lithium batteries are lighter and more convenient to drive.

From the perspective of service life, lithium batteries are also more advantageous. According to the test, lithium batteries can be charged and discharged more than 550 times, while lead-acid batteries are only more than 350 times, so the replacement cycle of lithium batteries will be longer than lead-acid batteries.

Finally, from the perspective of safety, lead-acid batteries are more advantageous. Because compared with lithium batteries, lead-acid batteries are relatively stable and are not prone to spontaneous combustion. However, due to the unstable discharge characteristics of lithium batteries, excessive discharge current makes the battery more prone to spontaneous combustion.

If you are buying an electric vehicle for the first time, if it is within the budget, you will give preference to lithium battery models. Although the lithium battery model is expensive, it has a longer mileage, a lighter body, and more convenient parking and charging.

Below 3,000 yuan, lead-acid models are preferred.

In order to save costs, electric vehicles below 3000 yuan generally use small-capacity lithium batteries (48V12-15Ah). In this way, the battery life is limited, and if you change to the 60V20Ah lead-acid battery version, the battery life can be about doubled.

When buying a new national standard electric vehicle, give preference to lithium battery models.

The new national standard electric vehicle has strict technical standard restrictions, lead-acid battery due to its own weight is too heavy, it will affect the strength of the body, usually only safe 48V12Ah lead-acid battery, not only bulky, but also not far. However, if you change to the 48v20ah lithium battery version, the range can reach more than 60 kilometers.

At present, lead-acid electric vehicles are the mainstay, and the main factor is the imperfection of technology. Although some lead-acid giants and electric vehicle giants have begun to develop lithium battery products, as a new field, many companies are currently exploring and exploring, and the initial products may often fail to reach the point of maturity.

Compared with lead-acid batteries, lithium batteries have a higher average voltage and higher energy density, in other words, batteries of the same size, lithium batteries have more capacity. In addition, lithium batteries are relatively lightweight, easy to carry, and have a much longer lifespan. In addition, lithium batteries are more adaptable to high and low temperatures, less affected by temperature, and more environmentally friendly.

Lead-acid battery:

Lead-acid batteries are widely used and widely studied by various electric vehicles in various countries because of their cheapness, abundant materials, high specific power, mature technology and manufacturing process, and high resource rate. As a labor-saving, convenient, fast, comfortable, inexpensive, and zero-emission personal transportation, electric bicycles have been widely accepted by people and have been valued by relevant national departments.

The research group of "Research on Development Strategy of Light Electric Vehicle Industry" participated by the Development Research Center, the Ministry of Construction, the Ministry of Science and Technology and other ministries and commissions put forward the report on "Research on Development Strategy of Light Electric Vehicle Industry". The number of electric bicycles in the country has reached more than 30 million. More than 95% of e-bikes use valve-regulated lead-acid batteries.

Now the common electric vehicle battery on the market is lithium battery and lead-acid battery, whether it is lead-acid battery or lithium battery, they have their own unique advantages and disadvantages, so there is no better way to say, can only say which is more suitable for themselves, after all, everyone's use is different, it is recommended to refer to the advantages and disadvantages of lead-acid battery and lithium battery, combined with their actual use, choose a more suitable electric vehicle battery. Here are the pros and cons of each:

Advantages of lead-acid batteries:

1. Good safety performance. Lead-acid batteries are easy to feed, let you fall and beat, repair a little, and you can continue to use.

2. Cheap. Lead-acid battery** is about 1 3 of lithium-ion batteries, which shows that its ** is very low.

3. Reversible repair. Lead-acid batteries can be used strongly, after the use of bad can go to the electric car store to trade in the new, make up the difference in price can be replaced with a new set of batteries, the loss is minimized, is a big benefit for the user. The lead in the battery can also be reused, reducing environmental pollution.

Disadvantages of lead-acid batteries: large weight, limited battery capacity, short life, lead-acid batteries are generally within 400 times of deep charge and deep discharge, and the life span is about three years.

Advantages of lithium-ion batteries:

1: Light weight and small size. The volume of lithium-ion batteries is 2 3 of the volume of lead-acid batteries, and the weight is about 1 3 of the weight of lead-acid batteries.

Lithium-ion batteries of the same volume have a higher capacity than lead-acid batteries, and the reduced weight makes electric vehicles lighter and has an increase in range by about 10%.

2: Long life. The average life of lithium-ion batteries is about 4 years, which is about one year higher than that of lead-acid batteries, with more than 500 times of charge and discharge, no memory of battery use, and strong shock resistance.

3: Overcharge resistance, good charge and discharge resistance. Lithium-ion battery At normal temperature, lithium-ion battery can be charged continuously for 48 hours without accidents such as battery expansion, leakage and rupture, and the capacity is kept above 95%. And under the dedicated charger, it can be charged and discharged quickly.

Disadvantages of lithium-ion batteries:

The production cost of lithium-ion batteries is high, and the labor cost of production equipment accounts for about 40% of the production cost, which is about three times that of lead-acid batteries. Its three times the cost performance is not high, it gives people a flashy feeling, and the lithium-ion battery can not be used, it can only be thrown away, or find a place to bury it, after thousands of years, future generations will dig it out and be an antique.

The safety performance of lithium batteries is worse than that of lead-acid batteries, especially in the case of high temperatures, which are prone to dangers, such as spontaneous combustion.

As a veteran lead-acid battery production group, Changxin Battery has excellent reputation and quality, and has been praised by the market for many years. As a high-end product in lead-acid batteries, Changxin graphene series adopts a more scientific direct connection structure, an upgraded formula with higher energy density, and a higher technology content, bringing longer life, longer endurance and more stable performance.

Hello, I think the electric vehicle battery or lead-acid battery is better, although the lead-acid battery is large and heavy, but the stability is much higher than that of the lithium battery, and it is not easy to cause spontaneous combustion, although the lithium battery is small and lightweight, but it is very unsafe.

The lead-acid battery is large and heavy, but the stability is cheaper than the lithium battery, and it will not cause spontaneous combustion line failure, except that the lithium battery is small and lightweight, but it cannot be squeezed and collided, and it will spontaneously combust when squeezed.

Each has its own merits. Lead-acid batteries** are low and maintenance-free, but they are also large in size and weight. Lithium batteries are small in size and light in weight, but they are expensive. Users can choose according to their needs.

Whether an electric vehicle is a lead-acid battery or a lithium battery is better, this is undoubtedly a lithium battery.

Lithium batteries have the advantages of light weight, strong discharge, high energy density, and fast charging speed.

The reason why some people say that lithium batteries are easy to cause accidents is that it was a thing of the past, and now lithium batteries are relatively safe.

This is generally much better than lithium batteries, especially in electric vehicles.

Lithium batteries are expensive or good, the charging speed is correspondingly fast, and the battery life is strong. Ordinary electric vehicle batteries are lead-acid batteries.

The lithium battery of electric vehicle battery is not easy to use in winter, but it is light in weight and has the capacity to be charged at any time. Lead-acid batteries are strong endurance and not afraid of freezing, and the disadvantage is that they are too heavy.

Most of the electric vehicle batteries are lead-acid batteries, and a small number of lithium batteries are lightweight, high and long-lasting.

It is better to choose lithium batteries for electric vehicle batteries, which can make your life happier.

Electric vehicle batteries should be lithium batteries better than lead-acid batteries.

Each has its own advantages and disadvantages:

Lithium battery: high quality, long life, flammable and small size.

Lead-acid: low, short life, reliable, large volume.

See your choices.

Lithium batteries for new national standard portable electric vehicles, and lead-acid for large electric vehicles.

Generally, there are two kinds of batteries for electric vehicles, there are lead-acid batteries and lithium batteries, I introduce the difference between the two batteries, lead-acid batteries are heavy, low specific energy, good safety, and low. Lithium battery is light in weight, high in specific energy, and not as safe as lead-acid battery, ** high, cost-effective two batteries should be cost-effective lead-acid batteries, which is also the main reason why electric vehicles still use lead-acid batteries.

Hello, happy to answer your questions.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

In the case of these two batteries, this lithium battery is still better, because the lithium battery will not be in danger in this harsh environment, such as being impacted or squeezed. Moreover, the lithium battery is relatively small affected by temperature, that is, when the temperature is particularly low, it has little impact on the amount of electricity used in the battery. So the service life of this lithium battery is longer than that of this lead-acid battery.

Lead-acid batteries and lithium batteries have their own advantages and disadvantages, the traditional lead-acid battery has a large weight and occupies a large area, the storage capacity is relatively small, and the mileage deviation is a little better, the lithium battery is slightly lighter in weight and occupies a small area, and the storage mileage is also large, which is expensive and has a slight safety hazard.

Lithium batteries are light in weight, large in capacity, expensive, long in use, relatively poor in safety, and less in use than lead-acid batteries, with high safety, heavy weight, and relatively short use time.
