What are the characteristics of lithium iron batteries?

●Stable discharge voltage. ●Good consistency between different batteries in the same batch. ●Long cycle life, after 2,000 charge and discharge, there is still 80% capacity remaining. ●Fast charging, which can be charged within 1 hour. ●Safety and high temperature resistance. How to charge lithium iron battery? The charger of the lithium iron battery is different from the ordinary lithium battery. The maximum terminal charging voltage of the lithium battery is 4.2 volts; the lithium iron phosphate battery is 3.65 volts. When the iron-lithium battery is charged, it is connected to the balance charging board. Generally, it is directly charged in series from both ends. The voltage of the charger is greater than the voltage of the battery pack. The cable detection of the voltage of each single cell is equivalent to connecting a zener tube in parallel. The charging voltage of the single cell will not exceed the voltage stabilization value, while the other single cells continue to be charged and charged through the zener tube bypass. (1) Constant voltage charging method: During the charging process, the output voltage of the charging power supply remains constant. With the change of the state of charge of the power lithium iron battery, the charging current is automatically adjusted. If the prescribed voltage constant value is appropriate, it can not only ensure the full charge of the iron lithium battery, but also minimize gas evolution and water loss. (2) Constant current charging method: During the entire charging process, the charging current is kept constant by adjusting the output voltage. Keep the charging current constant, the charging rate is relatively low. The constant current charging control method is simple, but because the acceptable current capacity of the lithium iron phosphate battery gradually decreases with the progress of the charging process, in the later stage of the charging, the power lithium-ion battery's power receiving capacity decreases, and the charging current utilization rate is greatly reduced. (3) Constant current and constant voltage charging method: The first stage adopts the constant current charging method to prevent excessive charging current at the beginning of constant voltage charging. The second stage adopts the constant voltage charging method to prevent the phenomenon of overcharging during constant current charging. Lithium iron phosphate batteries are the same as any other sealed rechargeable batteries. The charging must be controlled and overcharged, otherwise the battery will be easily damaged. Lithium iron phosphate batteries generally adopt a charging method of constant current first and then voltage limiting. Disclaimer: The articles published on this website are all from the Internet.
