402030 battery.Range of charging voltage for lithium iron phosphate battery packs

source:Industry News release time:2023-12-14 Hits: Popular:AG11 battery

　　Charging voltage range:

　　Generally, the upper charging limit voltage of lithium iron phosphate batteries is 3.7-4V, and the lower discharge limit voltage is 2-2.5V. Taking into account the discharge capacity, discharge median voltage, charging time, percentage of constant current capacity, and safety, a constant current and constant voltage charging scheme is adopted. For lithium iron phosphate batteries, the charging limit voltage is set at 3.55-3.70V, which is reasonable. The recommended value is 3.60-3.65V, and the lower discharge limit voltage is 2.2V-2.5V.

　　Lithium iron phosphate batteries have a 3.6V charging limit designed to fully activate the battery capacity without damaging the battery.

　　The number of charging cycles refers to the number of complete charging and discharging cycles. Although there is no overcharging at 3.4V, there will be a small number of participants who do not participate in the cycle charging and discharging, and the majority of participants will still have poor performance due to the increase in the number of cycles, leading to a vicious cycle until they cannot be used. This is the limitation of its lifespan, the inevitable combination of various harmful and unfavorable factors, and the inability to maintain the original design parameters in terms of performance.

　　Although the lithium iron phosphate battery pack has a design limited voltage, it is also equipped with a protective plate to protect the lithium battery pack from overcharging. But to make the lifespan of lithium battery packs longer, the correct charging method is also important.
