The charging method of both batteries is a constant current and then a constant voltage (CCCV), but the constant voltage points are different. The nominal voltage of a lithium iron phosphate battery is 3.2V, and the charging cut-off voltage is 3.6V. The nominal voltage of ordinary lithium batteries is 3.6V, and the charging cut-off voltage is 4.2V.
When the LFP battery is charged, lithium ions migrate from the surface of the lithium iron phosphate crystal to the surface of the crystal. Under the action of the electric field force, it enters the electrolyte, passes through the separator, and then migrates to the surface of the graphite crystal through the electrolyte.
The positive electrode material of lithium iron phosphate batteries is generally called lithium iron phosphate, and the negative electrode material is usually carbon. On the left is LiFePO4 with an olivine structure as the battery’s positive electrode, which is connected to the battery’s positive electrode by aluminum foil.
The nominal voltage of a lithium iron phosphate battery is 3.2V, and the charging cut-off voltage is 3.6V. The nominal voltage of ordinary lithium batteries is 3.6V, and the charging cut-off voltage is 4.2V. Can I charge LiFePO4 batteries with solar? Solar panels cannot directly charge lithium-iron phosphate batteries.
Lithium-ion batteries are particularly sensitive to overcharging and discharging, so avoid charging more than 100% or discharging less than 20%. Charging when the battery power drops to about 30% is recommended. Keeping battery power between 40-80% can slow down the battery’s cycle age. 2. Control charging time
After charging for a period of time, adding a shutdown time allows the ions generated at the two poles of the battery to diffuse, giving the battery a “digestion” time. This will greatly increase the utilization rate of the lithium-ion phosphate battery pack and improve the charging effect. Part 7. FAQs
