What is the service life of lithium iron phosphate battery packs

Based on various factors, the use characteristics of iron-lithium battery packs can be roughly expressed as: the size is relatively large, the low temperature performance is not good, and the relatively smooth attenuation rate can be maintained during the life span. Generally, it can be used for about 8 years; but if Used in the south. The life of lithium iron phosphate battery is longer than 8 years. The lifespan of lithium iron phosphate battery packs is 4-5 times longer than that of lead-acid batteries. For lead-acid batteries with relatively high technical content, there is no problem with the lifespan reaching 5 years. Because of the structural collapse of the negative electrode material graphite, lithium batteries will be scrapped even if they are not used for five years. I believe that most consumers have heard that the life of a lithium battery pack is 500 times, 500 times of charging and discharging, beyond this number, the battery will die, many friends in order to extend the battery life, every time the battery is fully charged Only charge when it is exhausted. Does this really extend the life of the lithium battery? The answer is not fixed. The life of a lithium battery is 500 times, which does not refer to the number of times of charging, but a cycle of charging and discharging. The lifespan of lithium iron phosphate battery packs is generally 300 to 500 charging cycles. Assuming that the power supplied by a complete discharge is Q, if the reduction in power after each charging cycle is not considered, the lithium battery can supply or supplement 300Q-500Q of power in its life. From this we know that if you charge 1/2 each time, you can charge 600-1000 times; if you charge 1/3 each time, you can charge 900-1500 times. By analogy, if it is charged randomly, the number of times is variable. In short, no matter how it is charged, it is constant to add a total of 300Q to 500Q of power. Therefore, we can also understand it like this: the life of a lithium battery pack is related to the total charge capacity of the battery, and has nothing to do with the number of recharges. Deep discharge and deep charge and shallow discharge and shallow charge have little difference in the impact of lithium battery life. In fact, shallow charging is more beneficial for lithium iron phosphate batteries. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
