Do you know how to use lithium battery UPS correctly?

1. The operating environment temperature must be suitable for the battery to work normally and keep it. For general batteries, the temperature of the environment should be guaranteed to be between 20-25 degrees Celsius, while the lithium battery UPS can be at -20-60 Work normally in degrees Celsius, without air conditioning, reduce equipment installation costs, maintenance costs, and electricity costs. 2. Regular inspections should be carried out. Regularly check the terminal voltage and internal resistance of each unit battery. During the operation of the lithium battery UPS power supply, due to the above-mentioned imbalance caused by the changes in the characteristics of each unit battery over time, it is impossible to eliminate it by the internal charging circuit of the lithium battery UPS power supply, so this characteristic has been obviously different. Balanced battery packs, if offline equalization is not taken in time, the imbalance will become more and more serious. 3. Under certain conditions, re-float the lithium battery. The UPS power supply has been shut down for more than 10 days. Before restarting, the UPS power supply should be started without load to re-float the lithium battery for 10-12h using the charging circuit in the machine. Run with load after the above. The UPS power supply is in a floating charge state for a long time without a discharge process, which is equivalent to being in a storage standby state. If this state lasts for too long, causing the lithium battery to become invalid due to long storage, it is mainly manifested in the increase of the internal resistance of the battery, which can reach a few in severe cases. Fourth, need to reduce the service life of deep-discharge lithium battery UPS is closely related to the depth of its discharge. The lighter the load carried by the lithium battery UPS power supply, the greater the ratio of the available capacity of the lithium battery to its rated capacity when the mains power supply is interrupted. When the lithium battery UPS power supply is interrupted by the mains power supply, and the lithium battery is used to supply power to the inverter, most of the lithium battery UPS power supplies will ring a periodic alarm with an interval of about 4s to notify the user that it is now supplied by the battery energy. When the alarm sound becomes rapid, it means that the power supply has been deeply discharged, and emergency treatment should be carried out immediately, and the lithium battery UPS power supply should be turned off. It is not imperative. Generally, do not let the lithium battery UPS power supply work until the automatic shutdown due to low battery voltage is over. 5. The peak power supply can be used for charging. For users who have long-term low-voltage power supply of the lithium battery UPS power supply or frequent power outages, in order to prevent the battery from being damaged prematurely due to long-term insufficient charging, the peak power supply (such as late night time) should be fully utilized. The battery is charged to ensure that the battery has sufficient charging time after each discharge. Generally, after a battery is deeply discharged, it takes at least 10 to 12 hours to recharge to 90% of the rated capacity. In this era of environmental protection and high efficiency, lithium batteries are the most suitable UPS batteries in line with the development trend of the times. With the continuous maturity of lithium battery technology, the advantages of using lithium batteries as UPS backup power sources are becoming more and more obvious. More and more companies have adopted it, and we see that lithium batteries are becoming an indispensable new friend in the data center computer room step by step.
