How to charge the lithium iron phosphate battery pack correctly?

The correct charging method of lithium iron phosphate battery pack ●It is recommended to use the CCCV charging method for charging the lithium iron phosphate battery pack, that is, first constant current and then constant voltage. The recommended constant current is 0.3C. Constant voltage recommendation 3.65. That is, 0.3C current charge in the constant current process, when the battery voltage reaches 3.65V, use 3.65V voltage constant voltage charging, when the charging current is lower than 0.1C (or 0.05C), stop charging, that is, the battery is already full. ●The charger of lithium iron phosphate battery pack is different from ordinary lithium battery. The highest termination charging voltage for lithium batteries is 4.2 volts; the lithium iron phosphate battery pack is 3.65 volts. When charging the lithium iron phosphate battery pack, it is the cable connected to the balance charging board. Generally, the whole charge is directly connected in series from both ends. The voltage of the charger is greater than the voltage of the battery pack. ●It is best to charge the lithium battery pack at a temperature within 0-45°C. This temperature is more conducive to the activation of the chemical properties in the lithium battery pack and makes the charging efficiency higher. ●When you get the lithium iron phosphate battery pack and want to use it formally, you must charge it, because the battery cannot be over-full when the lithium battery is stored, and the capacity will be greatly lost if over-full. Therefore, the charging precautions of the lithium battery pack are still more practical in the use of the lithium battery pack. ●Considering that when a single battery is charged in series, the inconsistency between battery packs will gradually increase. In order to ensure the service life of the battery, the only way to reduce the utilization rate of lithium battery packs and equalize charging is an effective method to reduce the inconsistency of battery pack characteristics. , Can balance the characteristics of the battery, thereby increasing the utilization rate of the iron phosphate battery pack and significantly prolonging the battery life.
