Today we will introduce how to properly maintain LiFePo4 batteries.
Factors that affect the life of LiFePO4 battery cell
1, Charge and discharge
Slow charging can extend the life of the battery compared with fast charging. It is best to use the charger with the stop charging function(such as anti-overcharge cut-off, negative voltage difference (-dV) cut-off and anti-overheating cut-off). To avoid lithium iron phosphate batteries due to overcharging and shorten the life of use.
We should avoid over-discharging the LFP cell to a very low voltage. The depth of discharge is the main factor affecting the life of lithium iron phosphate batteries. The higher the depth of discharge, the shorter the life of the LFP cell. In other words, simply reduce the depth of discharge, you can significantly extend the life of the LFP battery.
Not mixed use. Different capacity, different chemical structure or different charging levels, as well as a mix of old and new batteries, will make discharge too much. Which will constitute a reverse charge.
Assuming that a long time without charging lithium iron phosphate batteries, will reduce its life. LFP battery needs to keep electronic activity for a long time to reach its ideal life expectancy.
2, Operating environment
If we using the LiFePO4 battery cell at high temperatures for a long time, the electrode activity will decay. Then shortening the use of life. So try to adhere to the appropriate operating temperature. Which is a good way to extend the life of lithium iron phosphate batteries.
Prevent the accumulation of dust inside the pack, and maintain the battery inside the power supply on time. The depth of discharge is the main factor affecting the life of lithium iron phosphate batteries. The higher the depth of discharge, the shorter the life of the LFP cell. In other words, simply reduce the depth of discharge, you can significantly extend the life of the LFP battery.
LFP batteries require long periods of electron activity to reach their ideal life span.
The life span of LFP battery is followed by the number of times with the charge and decay. The general lithium iron phosphate battery charge is 3000-5000 times.
Lithium iron phosphate battery maintenance strategy
1, The temperature should be moderate
Temperature should not be too low and too high. If the operating temperature is higher than 35 ° C, the battery power will continue to reduce. The battery power supply time will not be as long as usual. If charging at such temperatures, the damage to the battery will be even greater. Even if storing in a hotter environment, it will inevitably cause corresponding damage to the quality of the battery. Therefore, trying to maintain a moderately favorable operating temperature is a good way to extend the battery’s life.
If used in a low-temperature environment, that is, below 4 ° C, it will reduce the life of LFP battery. Should avoid charging at 0 ° C or below.
2, The frequency of use should be in place
To play the maximum effectiveness of lithium iron phosphate batteries, you need to use it often. So that the electrons within the lithium battery is always in a state of flow. If you do not often use lithium, please be sure to remember to complete a monthly charge cycle. Do a power calibration, that is, deep discharge deep charge once.
3, Avoid mixing with metal objects
Do not mix the battery cell with metal objects. Avoid metal objects cause a short circuit and damage the battery or even causing danger.
4, The surrounding environment should be suitable
Lithium iron phosphate batteries should be in a clean, dry, ventilated environment. Should avoid contact with corrosive substances, away from fire and heat sources.
Lithium iron phosphate battery life we can generally get from its specifications on its theoretical life. But the actual use of life is generally a certain distance from the theoretical life. Good use habits can make the battery cell life extension.
Only in this way, lithium iron phosphate batteries can be properly maintained and remain healthy.
