What are the floating charging methods for UPS lithium iron phosphate batteries?

UPS lithium iron phosphate battery floating charge usage method: (1) Check discharge of lithium battery. Discharge the lithium battery UPS separately to investigate whether the lithium battery pack can meet the requirements of the maximum average load. This discharge method is called check discharge . The specific method is: choose to interrupt the work of the high-frequency switching power supply under the maximum load, and make the lithium battery pack discharge separately, so that the power required by the actual load is all borne by the lithium iron phosphate battery pack, and the lithium battery is calculated at the end of the discharge. The output capacity of the package. ⑵Strengthen the management of floating charging operation mode The floating charging operation mode is in the DC power system, the lithium iron phosphate battery pack is connected in parallel with the charging device equipment, as the only backup power supply for the substation DC power system. In the process of floating charge operation, due to the different internal resistance and self-discharge of each lithium battery UPS, their actual capacity is different, which is manifested in the inconsistent terminal voltage. UPS lithium iron phosphate battery charging method: The charger charges the UPS lithium battery with a constant current. As the battery voltage increases, the charger increases the charging voltage at the same time to speed up the charging speed. When the battery reaches the 4.2V cut-off voltage, the battery only charges about 70% (not full) at this time. At this time, the charger continues to charge the battery with a constant voltage and a gradually decreasing current, until the value is less than 0.1A and the battery voltage continues to rise when the battery voltage continues to rise before stopping charging. When charging lithium iron phosphate battery UPS and related products, the charger is best to choose the original special charger. Because the original charger is the most suitable in terms of voltage, charging speed, etc., it is also the least likely to damage the battery.
