Which is the best battery for electric vehicles? I ve heard that lead crystal batteries are good, ar

Now there are many kinds of electric vehicle batteries, the main ones are lead-acid batteries, divided into first-line products and second-line products, etc., the first-line products mainly include Tianneng, Huafu, Chaowei, etc., the second-line products will not be said, if it is good, many people will say that it is Tianneng or Huafu, but I am doing battery repair work, I think that Chaowei brand electric vehicle battery is currently the best electric vehicle battery in China.

I have also paid attention to the lead crystal battery for a while,I have read a few articles on the Internet,In fact, it is a kind of propaganda means for merchants,There is not much difference from ordinary valve-regulated lead-acid batteries,This is the same as the so-called digital TV in the past,There is no digital signal,Where did the digital TV come from。

There are too many varieties of batteries, so it's more practical to ask other people around you who have used them. There are also top ten battery brands on the Internet, which can also be referenced.

There are many kinds of electric vehicle batteries, and generally lead-acid batteries are the most widely used. As far as lead-acid batteries are concerned, there are many kinds of lead-acid batteries, and different processes will be used in the production of plates according to the use, for example, the plates of the start-up battery are thicker than those of the power battery, and the lead paste should be looser. There is no special electric vehicle battery, theoretically any battery can be used, but some batteries are not suitable for electric vehicles, such as the starting battery shock resistance, over-discharge, not as good as the power battery, and the life of the electric vehicle is easy to shorten.

Lithium batteries are also very good for electric vehicles, and the large volume-to-mass ratio is its biggest advantage, but it is very expensive.

Lead-acid ones are also good. The new brand Leopard is lead-acid.

I heard that the lithium battery for electric vehicles is good, is it true or false?

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 of "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 statement, 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 old for the new, make up the difference in the 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 a lithium-ion battery is 2 3 of the volume of a lead-acid battery, and the weight is about 1 3 of the weight of a lead-acid battery.

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.

Lithium battery. For electric vehicle users, many people may be more inclined to lithium batteries, from the quality point of view, lead-acid batteries are larger, heavier, non-removable, and think more bulky than lithium batteries weighing only a few kilograms. Lithium batteries are smaller, very portable, and removable, and the operability is better than lead-acid batteries, especially for women, lithium batteries are more acceptable, because even women can easily pick them up, which is very convenient.

Precautions for the use of electric vehicle batteries.

Try not to carry people or heavy objects when riding an electric vehicle to avoid straining the battery.

If the charger does not have a temperature compensation function, it should be charged at room temperature (25) as much as possible (indoors, especially when used in winter), and the charger will continue to charge for 2 3 hours after turning green, and then cut off the power supply.

After the battery of the electric vehicle is exhausted (the undervoltage light is on), the power should be turned off, driven by manpower, and do not use the "recovery voltage" to exercise.

In fact, some experts in the industry have given advice, if the battery is lower than 72V40A, it is recommended to choose a lead-acid battery, firstly, the lead-acid battery ** is lower, and the old can also be traded-in, secondly, the lead-acid battery has high stability and low safety hazards.

If it is greater than 72V40A, it is recommended to choose a lithium battery, lithium battery discharge performance is good, generally choose a large-capacity battery, the car itself must have a higher power, choose a lithium battery, there will be no discharge, and the lithium battery supports high-power charging, unlike lead-acid to charge a night, from the above points can be seen, lithium batteries will not completely replace lead-acid batteries for the time being.

Reason 1: Lithium batteries are expensive

The reason why lithium batteries can not completely replace the current lead-acid batteries, the most important reason is that the sale of lithium batteries is more expensive than lead-acid, lithium batteries because the manufacturing is more complex, the cost is two or three times that of lead-acid batteries, so the factory will naturally be more expensive, since it is the owner of the electric vehicle, most people are actually more willing to accept the lower cost of lead-acid batteries.

Reason 2: Lead-acid batteries are more acceptable

Judging from the development history of electric vehicles over the years, lead-acid batteries have always been the mainstream of electric vehicle batteries, compared with lithium batteries that have only emerged in recent years, consumers of electric vehicles have a higher acceptance and recognition of lead-acid batteries.

Reason 3: Lead-acid battery technology is more mature

Although the research and development of lithium batteries has a history of several decades, compared with the history of lead-acid batteries for more than 100 years, there is no doubt that the technology of lead-acid batteries will be more mature.
