What brand of electric vehicle battery is better If you want a lead acid battery, you don t need to

The best quality EV batteries (within the industry) are ranked as follows:

1) Panasonic battery (foreign-owned Panasonic).

2) One battery (Hong Kong Afirstpower) 3) Hypertherm battery (Shanghai) 4) Tianneng battery (Zhejiang).

5) Ningbao battery (Yinchuan).

6) Wuwei battery (Gansu).

7) Aojiang battery (Guangdong).

8) Jiawei battery (Shandong).

9) Changsheng Battery (Zhejiang).

10) Chaowei battery (Zhejiang).

Among them, high-quality internalized batteries include Panasonic batteries, Hypertherm batteries, and one-battery batteries. The rest are ordinary externalized batteries.

I hope it will help you for your reference.

Tianneng 12 A is better than Chaowei 20 An, Feipu battery is good, I changed out of Feipu battery also has more than 20 groups, the repair rate is basically zero, a price is a penny, now Tianneng battery ** is relatively low, Feipu's popularity is not very high but **slightly higher than Tianneng, I believe that a price is a penny.

Asahi Pai, I do this piece, and I still know a lot about it. Asahi battery is very good in the internal formation technology. You can consider:

It's not very clear, my electric car seems to be Asahi Pai, the quality is still okay, and it is more power-efficient. When the electric car was first bought, it was equipped with Tianneng, I was angry, I used it for 4 months, I drummed out a big bag, I asked them to return, but I didn't return it, the after-sales service was really poor, and it was still endorsed by celebrities, and I couldn't look at the brand.

Lead-acid batteries must be internalized, and internalized into power and water saving. At present, only Xupai battery is fully realized in the internal chemical technology, and Xupai production base is not as much as Chaowei and Tianneng, the technology is updated quickly, Chaowei has not yet been fully realized, and it may be almost the same next year, Tianneng has too many production bases, and it will be late, especially for those acquired factories It is difficult to update the technology, which is why the quality of Tianneng batteries is poor recently.

In the case of electric vehicles, the green source has a very high anti-theft coefficient, and the cars in general stores will be equipped with special batteries. The battery warranty period is 1 2 years, generally 15 months, but some are 24 months, the landlord looks at it!!

I think it's still Tianneng and Chaowei.

From the point of view of service life, lightness, and endurance, lithium electric vehicles are more advantageous, and from the perspective of product quality, safety, and maintenance costs, lead-acid electric vehicles are more advantageous.

1. Service life.

From the perspective of service life, the full charging and discharging times of lead-acid electric vehicles are about 350 times, while the complete charging and discharging times of lithium electric vehicles are about 500 times, which means that the battery life of lithium electric vehicles is longer than that of lead-acid electric vehicles.

2. Lightness.

From the perspective of lightness, two electric vehicles of the same model, lead-acid electric vehicles are relatively bulkier, while lithium-ion electric vehicles are lighter. Therefore, when riding, the experience of lithium electric vehicles will be better than that of lead-acid electric vehicles.

3. Endurance.

From the perspective of endurance, the vast majority of lithium-ion electric vehicles have the characteristics of long battery life, which are generally better than the same type of lead-acid electric vehicles, but the gap is not large.

4. Product**.

From the point of view of products, because lithium batteries are much higher than lead-acid batteries, lithium electric vehicles of the same model are significantly higher than lead-acid electric vehicles. In addition, it is important to know that lithium batteries** are very valuable, while lead-acid batteries** are even more valuable.

5. Security.

From the perspective of safety, lead-acid batteries are relatively mature in technology and stable in product characteristics due to years of development, which means that the battery is not prone to safety risks. Lithium batteries have many advantages, but due to their poor stability, they are more prone to problems than others.

Answering lithium batteries is better. In terms of life comparison, the cycle life of lithium batteries can reach 800-1000 times, and the service life is long; The cycle life of lead-acid batteries is less than 500 times, and the service life is short. For batteries of the same size, lithium batteries have a larger battery capacity, and lithium batteries are more environmentally friendly than lead-acid batteries, and they can be used up after use; Lead-acid batteries are not properly disposed of after disposal, which will cause pollution to the environment.

Lithium iron phosphate batteries have strong durability, slow consumption, more than 1000 times of charging and discharging, and no memory, and the general life span is 4-5 years. Lithium iron phosphate batteries can be discharged with high current, which is suitable for electric vehicles, electric bicycles, etc. In terms of volume and quality, lithium batteries are relatively small.

In the same volume, the capacity of lithium batteries is larger than that of lead-acid batteries. Lead-acid batteries have a capacity of around 20 amps, while lithium batteries have a capacity of 8-10 amps.

No matter what state the lithium iron phosphate battery is in, it can be charged and used at any time, and there is no need to put it out and then charge it. Lithium materials do not contain any toxic and harmful substances, and are considered by the world to be green and environmentally friendly batteries, which are non-polluting in production and use, and have become a hot spot of widespread concern and research. Lithium iron phosphate has undergone rigorous safety tests and will not produce even in the worst traffic accidents, showing higher safety performance.

The lead-acid battery is generally deeply charged and discharged within 300 times, has memory, and has a life span of about two years; And there is liquid in the lead-acid battery, and after consuming it for a period of time, it is found that the battery is hot or the charging time becomes shorter, so it needs to replenish the liquid. Under the same specification capacity, the volume and weight of lead-acid batteries are large, and there is a large amount of lead and a large amount of acid in the battery, which will cause pollution to the environment if it is not disposed of properly after disposal.

Lead-acid battery electric car is good.

First, the advantages of lithium battery electric vehicles.

1. Long cycle life: The lithium-ion battery is charged and discharged at a rate of 1C, and its cycle life is greater than or equal to 500 times, and the capacitance at the 500th time is greater than 70% of the nominal copper beam. Even if the lead-acid battery is discharged and charged, its cycle life is less than or equal to 350 times, and the electric capacity is less than or equal to 60%.

2. Good low-temperature discharge performance: lithium-ion batteries can work normally at -25 degrees, and their capacitance can reach 70% of the nominal capacity, while lead-acid batteries can work normally at -25 degrees at 50% of the capacitance at -10 degrees.

3. Strong charge retention ability: After placing the fully charged lithium-ion battery pack for two months, its current capacity is greater than or equal to 80%, while the lead-acid battery is only 40%-50% of the nominal capacity after two months.

4. Strong continuity ability, because the weight of the lithium-ion battery pack is only 30% of that of the lead-acid battery, the lithium-ion battery has a strong continuation ability under the same voltage and capacity.

5. High specific energy: Since the volume of lithium-ion batteries is only 30% of that of lead-acid batteries, the energy reserve of lithium-ion batteries is larger than that of lead-acid batteries when the same space is used.

Second, the advantages of acid battery electric vehicles.

1. Safety sealing: In normal operation, the electrolyte will not leak out of the terminals or shells of the battery.

2. No free acid: The special suction separator keeps the acid inside, and there is no free acid inside the battery, so the battery can be placed in any position.

3. Degassing system: After the internal pressure of the battery exceeds the normal level, VRLA (Valve-regulated Lead Acid Battery"VRLA battery"The battery will release excess gas and automatically reseal it to ensure that there is no excess gas inside the battery.

4. Simple maintenance: Due to the unique gas composite system, the generated gas is converted into water, and there is no need to add water in the process of using the battery.

5. Long service life: the lead-calcium alloy steeplechase with anti-corrosion structure is adopted, and the battery can be floated for 10-15 years.

Of course, lithium batteries are good!! The advantages are as follows:

1. Ultra-long life, the cycle life of long-life lead-acid batteries is about 300 times, and the highest is 500 times, while lithium iron phosphate power batteries have a cycle life of more than 2000 times, and the standard charging (5-hour rate) can reach 2000 times. The lead-acid battery of the same quality is "new half a year, old half a year, maintenance and maintenance for half a year", at most 1 year, and lithium iron phosphate batteries are used under the same conditions, it will reach 7 8 years can be said"Lifetime"。All things considered, the performance** ratio will be more than 5 times that of lead-acid batteries.

Second, the use of safety, lithium iron phosphate completely solves the problem of lithium cobalt oxide and lithium manganese oxide safety hazards, lithium cobalt oxide and lithium manganese oxide in a strong collision will produce a threat to the life safety of consumers, and lithium iron phosphate to go through strict safety tests even in the worst traffic accidents will not produce the most distinctive lithium battery.

3. It can be quickly charged and discharged with a high current of 2C, and the battery can be fully charged within 40 minutes of charging under the special charger, and the starting current can reach 2C, while the lead-acid battery does not have this performance now.

Fourth, high temperature resistance, lithium iron phosphate electric heating peak can reach 350 -500, while lithium manganese oxide and lithium cobalt oxide are only about 200.

Fifth, large capacity, lithium iron phosphate power battery mileage is the same quality lead-acid battery 3-4 times, its advantages can make the electric bicycle under the premise of moderate weight, a charge can run more than 100 kilometers, for office workers, a charge can be used for about a week. The lead-acid battery equipped with the electric bicycle in the vehicle weight does not exceed the standard, its maximum battery capacity of 12ah (the weight of the lead-acid battery has reached 13 kg at this time, and the weight of the same capacity lithium iron phosphate battery is only 5 kg), a charge can be up to about 50km.

6. Non-memory effect rechargeable battery works under the condition of being full and not discharged, and the capacity will quickly fall below the rated capacity value, which is called memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is no such phenomenon in lithium iron phosphate batteries, no matter what state the battery is in, it can be charged and used at any time, and there is no need to put it out and then charge.

7. Small size, light weight, the volume of lithium iron phosphate batteries with the same specification capacity is 2 3 of the volume of lead-acid batteries, and the weight is 1 3 of lead-acid batteries.

8. Green environmental protection.

Although the ** high point, it is still very cost-effective for long-term use.

There is no doubt that lead-acid battery, as a power battery, has its advantages in design. The advantage is that it provides a larger open-circuit power supply (compared to lithium batteries). A 12V battery only needs to be made into a battery, and a lithium battery may need to be connected in series to form a battery pack when it is used as a power battery.

For the design of power batteries, lead-acid batteries can be relatively easy to do, while lithium batteries need to encounter many problems in design, later charging, use and maintenance. In terms of manufacturing costs, the current power battery, the former is more than the other, and the latter is higher. But the latter is the way of the future.

The fatal disadvantage of lead-acid batteries is that the traditional battery is like a large stone weighing about 20 kilograms when installed on a bicycle, and its own weight is loaded with load, so that the driving range is not ideal. Such a heavy battery is charged up and down, which makes people feel sad. The battery is also swollen and unsightly in the car.

The life of the battery itself also annoys consumers, and it will not take long for the battery to be scrapped, and the scrapped battery will also produce serious environmental pollution and excessive quality. With a lithium battery, it is loaded in the front basket of the bicycle, and the driving range is 63 km (load 75 kg) at one time, and the maximum speed is 20 km per hour. The portable battery compartment is only 24 centimeters long and 26 centimeters wide.

Flow-type car body, front and rear shock absorption, dexterous and fast. Only lithium motor vehicle batteries can be assembled into such a lightweight bicycle with less environmental pollution. I think that in the future, in the market, in terms of choosing the type of power battery, the two will be more competitive.

It is possible that the latter will replace the former as the technology continues to mature. On the other hand, lead-acid battery technology is also constantly updated. For example, the continuous development and maturity of lead cloth technology and thin plate technology will have an impact on the entire power battery market.

We can expect that too!

Which lead-acid battery or lithium battery in the electric vehicle battery has its own advantages, which is reasonable.

In terms of safety, it is definitely good for lead-acid. The commercial application of lithium batteries must be equipped with protection devices, but the safety is still not as good as that of traditional lead-acid batteries. If you buy a lithium battery, try not to charge it at home.

Isn't the current electric car, the iphone**, all the problems of lithium batteries.

Of course, lithium batteries are good, and the lithium batteries used in electric vehicles are generally lithium iron batteries, but they should be more expensive.

Compared with lead-acid batteries, they are of the same size, lighter, have a higher capacity (longer riding distance), and have a stronger discharge ability (more powerful climbing). Charging will not have a memory effect, lead-acid batteries are easier to vulcanize, but lithium batteries also have higher requirements for chargers, so electric vehicles with integrated lithium batteries will be more expensive.
