Which electric car battery is better, and which battery car battery is better

From the perspective of market share, the ranking should be lead-acid batteries, lithium batteries, graphene batteries, gel batteries, of which lead-acid batteries can be said to be an unshakable position, the current market of electric vehicles, more than 80% are using lead-acid batteries, and lithium batteries are generally used in high-end electric vehicles and ultra-high endurance electric vehicles, and graphene batteries and gel batteries are mainly used in specific models of models.

No matter what product, whether it is enough to buy an important factor is inseparable from the first one, especially the electric vehicle battery, a battery is accounted for one-third to two-thirds of the cost of the electric vehicle, it largely affects the price of the electric vehicle, so the difference between the battery and the car has to be considered when buying a car.

From the point of view of the battery, the sorting should be lithium battery, graphene battery, gel battery, lead-acid battery, of which lithium battery and graphene battery should be relatively expensive in price, basically more than 1,000 yuan, and even some large-capacity batteries, ** can reach 2000 yuan, which is more expensive than an electric car with a lead-acid battery, and lead-acid batteries are relatively more close to the people, and the old battery also has **value, so ** is also its core advantage.

The common electric vehicle batteries on the market are lithium batteries and lead-acid batteries.

Whether it is a lead-acid battery or a lithium battery, they have their own unique advantages and disadvantages, so there is no better way to say, only to say which one 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 batteries and lithium batteries, 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.

There are several battery factories that produce electric vehicles in the country, and the batteries used in various brands of electric vehicles are basically produced by these manufacturers, and they are all produced in accordance with national technical standards, so the quality is almost the same. The so-called special batteries of the same brand in some factories are actually customized for these cars.

The better battery batteries are: lead-acid batteries, lithium batteries, gel batteries and nickel hydrogen batteries.

First, lead-acid batteries.

is the most commonly used battery for electric vehicles.

Most of the two-, three- and four-wheeler batteries on the market are lead-acid batteries, and their electrodes are made of lead and oxide, where the electrolyte is a sulfuric acid solution.

This kind of battery is used for a very wide range of purposes, and the price is relatively moderate, there are many types, the battery capacity is large, the key is that the process is relatively mature, the cost of maintenance is relatively low, and the lead-acid battery adopts the lead-calcium alloy steeplechase of the first-class room structure, so that the service life of the lead-acid battery is relatively long.

Of course, lead-acid batteries also have their own shortcomings, that is, the volume is relatively large, and it is heavier, and it occupies a large space in the car, and the other is that the battery contains a lot of lead, which is easy to cause environmental pollution, so the waste battery should be sent to a special maintenance point in time and cannot be discarded casually.

Second, lithium batteries.

Lithium battery is relatively lightweight, light weight, it uses a non-aqueous electrolyte battery, when discharging lithium ion is unplugged, when charging lithium ion inserted, because lithium battery has high storage energy, usually lead-acid battery several times, so the same volume and weight of lithium battery is more durable than lead-acid battery, longer mileage, longer service life.

However, lithium batteries also have their own determination, that is, the safety is not as stable as lead-acid batteries, and the price is relatively high, and the price of lithium batteries with the same volume and weight is several times that of lead-acid batteries.

Third, gel batteries.

Colloidal lead-acid battery is a kind of improved battery on the basis of lead-acid battery, it uses a gelatinous electrolyte, there is no free liquid inside, so the use efficiency is higher, generally in the same volume, the capacity of colloidal lead-acid battery is larger, so the heat capacity is larger, and the heat dissipation ability of this battery is strong.

In addition, the stability of the gel battery is very good, it can withstand long-term discharge or deep discharge, and there are special characteristics of overcharge and overdischarge. If we talk about the disadvantages, it is that the price is relatively high.

Fourth, nickel-metal hydride battery Zheng Kai.

NiMH battery is a kind of alkaline battery, this kind of battery has high power, and the current can be discharged smoothly when working, the safety performance is good, the cycle life is long, and its weight is relatively light.

But the disadvantages of this battery are also obvious, that is, the battery capacity is relatively small, the weakness is that the mileage is relatively short, and the price is relatively high, and there is another point, this kind of battery has memory characteristics, and the battery must be used up to charge, so it is used less in electric vehicles.

Prospect for the development of battery cars:

Whether from the perspective of environmental protection or energy, the future of electric vehicles need to have a big development, its development will be related to the rise and fall of many industries, may become a new economic growth point in the future in China, electric slag car has a unique market.

As a small, medium-speed and short-distance daily transportation, electric vehicles are very ideal, and they have unique development conditions and broad application prospects in China. <>

Hello, lithium battery is good. At present, there are three main types of Bi electric vehicle batteries on the market: lead-acid batteries, nickel-metal hydride batteries and lithium batteries.

Lithium batteries have the characteristics of long life and high stability, and their life is more than twice that of other battery types. 3.High energy utilization:

Lithium batteries are efficient at converting stored energy into power. 4.Eco-friendly:

Lithium batteries do not use heavy metals, will not cause environmental pollution, and can be used. When choosing a loss-making electric vehicle battery, you also need to consider the actual needs and budget. Some lower-priced EVs may use lead-acid or nickel-metal hydride batteries, which are cheap but do not last long and have a weak power storage capacity.

Some high-end electric vehicles use lithium batteries, but they are also higher. Therefore, when choosing an electric vehicle battery, you should balance and choose according to your financial ability and regret your needs. <>
