Combien de temps sont les temps de cycle et la durée de vie réelle de la batterie LiFePO4?

How many years is the real life of lithium iron phosphate battery pack? En réalité, the service life of lithium battery packs is similar. Whether it is lithium iron phosphate battery or ternary lithium battery, the actual service life is related to the user’s use method and protection.

What is a lithium iron phosphate battery?

Lithium iron phosphate battery is a kind of lithium ion battery, which refers to a lithium ion battery using lithium iron phosphate as the positive electrode material. It is characterized by strong safety and stability, high temperature resistance and good cycle performance.

How long is the real life of lithium iron phosphate battery pack?

The cycle life of long-life lead-acid batteries is about 300 fois, and the highest is 500 fois. The lithium iron phosphate power battery has a cycle life of more than 2000 fois. Lead-acid batteries of the same quality are “new for half a year, old for half a year, and maintained for half a year”, which is 1 à 1.5 years at most, while lithium iron phosphate batteries are used under the same conditions, and their theoretical life will reach 7 à 8 années.

Lithium iron phosphate battery packs are generally available for about 8 années; but if they are used in the south. The life of lithium iron phosphate battery is longer than 8 années. The theoretical life of the lithium iron phosphate battery pack also exceeds 2000 charge and discharge cycles, even if it is charged once a day, it can last for more than five years. En général, it is charged once every three days for daily household use, and it can be used for about eight years.

The service life of the lithium iron phosphate battery pack is about 5000 fois. The battery has its own number of cycle discharges (tel que 1000 fois) when it is produced. If it exceeds this number of charges and discharges, the battery will die, and the complete discharge will seriously affect the use of the battery. , so don’t over discharge it.

Advantages of lithium iron phosphate battery pack compared with lead-acid battery:

1. Grande capacité. Lithium battery cells can be made into 5Ah~1000Ah (1Ah=1000mAh), while lead-acid battery 2V cells are usually 100Ah~150Ah, and the variation range is small.

2. Poids léger. The volume of the lithium iron phosphate battery pack with the same capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the latter.

3. Strong fast charging capability. The starting current of the lithium iron phosphate battery pack can reach 2C, which can realize high-rate charging; the current requirement of the lead-acid battery is generally between 0.1C and 0.2C, which cannot achieve fast charging performance.

4. Protection environnementale. Lead-acid batteries contain a large amount of heavy metal-lead, which produces waste liquid, while lithium iron phosphate battery packs do not contain any heavy metals, and there is no pollution in production and use.

5. High cost performance. Although lead-acid batteries are cheaper than lithium iron phosphate batteries because of their cheaper materials, they are less economical than lithium iron phosphate batteries in terms of service life and daily maintenance. Practical application results show that the cost performance of lithium iron phosphate batteries is more than 4 times that of lead-acid batteries.
