As a new type of lithium-ion battery, lithium iron phosphate battery is widely used due to its high safety and long cycle life. In order to extend the service life of the battery and improve its performance, correct maintenance is particularly important.
Maintenance methods of lithium iron phosphate batteries
Avoid overcharging and over-discharging:
Overcharging: After the lithium battery is fully charged, the charger should be unplugged in time to avoid being in a charging state for a long time, which will generate too much heat and affect the battery life.
Overdischarging: When the battery power is too low, it should be charged in time to avoid excessive discharge, which will cause irreversible damage to the battery.
Shallow charge and discharge:
Try to keep the battery power between 20%-80%, and avoid frequent deep charge and deep discharge. This method can effectively extend the cycle life of the battery.
Control the use temperature:
The operating temperature range of lithium iron phosphate batteries is generally between -20℃ and 60℃. Avoid exposing the battery to extremely high or low temperature environments, which will affect the performance and life of the battery.
Avoid high current discharge:
High current discharge will generate a lot of heat and accelerate battery aging. Therefore, frequent high current discharge should be avoided.
To avoid mechanical damage:
Avoid mechanical damage to the battery such as squeezing, collision, bending, etc. This may cause an internal short circuit in the battery and cause a safety accident.
Regular inspection:
Regularly check the appearance of the battery for deformation, damage, etc. If any abnormality is found, use should be stopped immediately.
Proper storage:
When the battery is not used for a long time, it should be placed in a cool, dry place and maintained at a certain level of power (about 40%-60%).
Common misunderstandings
Freezing batteries: Freezing will damage the internal structure of the battery and reduce battery performance.
Charging in a high temperature environment: Charging in a high temperature environment will accelerate battery aging.
Long-term non-use: Long-term non-use will cause battery sulfation and affect battery capacity.
