Lithium iron phosphate batteries are more preferred for new energy electric vehicles. In recent years, many iron lithium battery manufacturers have emerged, which leads to a lot of phosphate battery brands on the market, and the price is also uneven. So how to judge the lithium iron phosphate battery which brand is good, it has become a problem with battery users.

Let's let the Grip battery manufacturer briefly tell us what is the brand of lithium iron phosphate batteries. For consumers, regardless of which brand is battery, the battery is mainly judged from the following aspects: 1. Safety of lithium iron phosphate batteries in lithium batteries, recognized LIFEPO4 is a positive material Battery has the best safety performance.

Mainly due to the good oxygen retention capacity of LifePO4 under high temperature conditions, even if the high temperature of more than 500 ¡ã C does not oxygen, more than lithium diamondic acid, lithium manganate and three-yuan materials are much higher. But under abusive conditions, even if LifePo4 is a lithium battery, there will be security issues. Second, the price of lithium iron phosphate battery price is three quotes, one is only the price of lithium iron phosphate battery cells, the other is the price of lithium iron phosphate battery does not add protective plate, the last one is the protector the price of.

The price of these three ways is completely different. Let's take a look at it: 1. Only buy phosphithicate battery electrical iron lithium battery cell has a new battery and ladder battery, and the new battery is from raw materials to the cost of the process of the new product, ladder The core refers to the cells used in the secondary use, such as the lithium iron phosphate battery for new energy vehicles.

After the battery is attenuated to a certain extent, it cannot meet the power or capacity of the car, but the battery is not bad, after a certain fix adjustment Can be used on the next level. Such as communication base station spare power, electric bicycle, part 3C product, etc. Therefore, some people often find that different merchants have a big difference, some or even 8 yuan 1AH to 2 yuan.

In the low quotation, most of them are lithium iron phosphate cells. Of course, it is not good to say that the battery cell is not good, this depends on the specific product application needs. 2, only buy the lithium iron phosphate battery does not protect the protector in such a form, there is a new battery and the ladder battery, so when buyers, the buyer is best to understand the price quoted by the battery supplier is a new phosphate.

The price of iron lithium batteries is still the price of the ladder battery. In general, the price quotation of the ladder battery is almost the conflict of the new battery. The lithium iron phosphate battery that does not protect the protector is basically a battery of the monomer, and the parallelism of the cell is basically in the range of the cell, since the lithium iron battery cell is not very good, so it can The number of electrical cores used in series and in parallel is limited, and the general voltage and capacity of such batteries are not very large, it is very easy to issue problems.

In general, there is currently the powerful lithium iron phosphate battery manufacturer's phosphate battery electrical core offer, the basics provided are all new batteries, the price is around 8 yuan 1, is the ladder, lithium iron phosphate battery manufacturers, offer Generally, around 6, 1ah, some or even about 1AH. 3, lithium iron phosphate battery plus protective plate lithium iron phosphate battery plus protective plate, this battery is generally a single battery or battery pack of 12V, which is the same as a new and ladder battery. Such battery prices differ from the second point above, the difference is mainly on the battery protection plate, the battery protection board difference is that the functional differences and the cost of the components.

Therefore, the price of lithium iron phosphate battery plus protective board will have a large difference in different manufacturers. But no matter what, we must first understand our actual needs when buying lithium iron phosphate batteries, then choose the right product to maximize our own economic benefits. Third, lithium iron phosphate battery life At present, the lithium iron phosphate battery on the market is about 2,000 cycle life.

This refers to the ideal number of the application in a smooth normal small current charge and the normal temperature environment, but in different cases , Lithium iron phosphate battery real life cycle number is different. This is mainly how to use the life life of several different uses. 1 Battery brand manufacturers have strong strength, good quality, basically more than 200,000 cycling life; small lithium battery manufacturers, the quality is more than 1,000 cycle life; (2) High-speed stable charge and discharge The application of the magnification discharge, most of which is a power-based lithium battery, most is the application of the application to power the motor, such as new energy vehicles, electric vehicles, fishing boat power supply, etc.

Since most of the lithium iron phosphate batteries operate in high load conditions, speed up the battery material attenuation time, the cycle life is a sharp drop, the quality of the poor quality, possibly about 500 cycles; strong lithium iron phosphate battery brands Manufacturers, better in equipment technology and materials, the quality of the battery will be better, but the loop life is around 800 times. (3) High-magnification unstable charge and discharge use I think that the lithium iron phosphate battery used in this case, the life will be shorter, 300 left and right is almost scrapped. Unstable discharge used by the battery, low when the time is high, the battery is decolifies promotes greater.

2. Lithium iron phosphate battery high temperature environments use phosphate battery high temperature performance is currently not very mature, operating temperature -20 ¡ã C to 125 ¡ã C, this temperature range is theoretical, the actual application temperature range is small. (1) Small current charging is normal in this field, if the battery brand manufacturer is relatively strong, the quality is good, basically more than 1000 cycle life; small lithium battery manufacturers, The quality is a little more than 500 cycle life; because of the use of high temperature, it is relatively large.

(2) High-temperature stable charge and discharge use of high-temperature high-magnification discharge applications, most of them are power-based lithium batteries, mostly the application of powerful lithium battery manufacturers in domestic powerful lithium battery manufacturers More use in new energy vehicles, electric vehicles, fishing boat electromechanical power, etc. Since most of the lithium iron phosphate batteries operate in high load conditions, speed up the battery material attenuation time, the cycle life is a sharp decline, the quality of the poor quality, may also be 300 cycles; strong battery brand manufacturers, The equipment technology and materials will be better, and the quality of the battery will be better, but the loop life is about 500 times. (3) High-temperature discharge and discharge and discharge use high temperature discharge retroactivity unstable operation, the battery is more damage, the loop service life is relatively low, and the test of several battery manufacturers is found, 250 to 300 times, the battery is basically used.

Can't. 3, lithium iron phosphate battery low temperature environment to use low temperature environments to perform the performance of the phosphate battery and high, on the current market situation, the lithium iron phosphate battery is working below -20 ¡ã C to -40 ¡ã C The life expectancy is significantly dropped, the discharge current range is 0.2c to 1c, the discharge capacity is 50% to 60%, the temperature is also low, the worse discharge capacity.

Therefore, there are no low-temperature phosphate batteries in the market, the low temperature phosphate cells of mature applications, the temperature range - 20 ¡ã C to 55 ¡ã C, the cycle life is 300 times. The above is about how to judge the basic knowledge point of the phosphate battery which brand is good, I hope to help eve.
