How to properly use lithium-ion battery UPS

1. Ambient temperature is an important factor that affects the life of lithium-ion battery UPS. Generally, the appropriate ambient temperature required by the battery is between 20 and 25°C. When the ambient temperature exceeds 25°C, the battery life will be shortened by half for every 10°C increase. 2. The operating environment of lithium-ion battery UPS needs to be well ventilated to help dissipate heat, while maintaining a clean environment. Do not carry inductive loads to prevent damage to the uninterruptible power supply. 3. It is necessary to strengthen the management of daily inspections and maintenance, check whether the equipment has alarms, odors, and abnormal noises, check the loosening of the joints and the operation of the cooling fan, and check whether the instructions of the equipment are normal. Once problems are found, they must be dealt with in time. 4. The pan-geographic portable high-capacity UPS power supply adopts high-performance lithium-ion batteries and is manufactured with the most advanced lithium-ion battery technology. It has strong output energy and provides two modes of AC output and DC output. It can be used as an online UPS power supply, but also as an outdoor backup power supply. 5. When using lithium-ion battery UPS, you need to check the parameters of the UPS. Each UPS is not allowed to operate at full load, and a power margin of more than 20% must be maintained, and the load must be controlled between 40% and 60% of the additional output power of the UPS. 6. When the lithium-ion battery UPS is in operation, due to the difference in function and quality, it will cause damage to the single battery function and the storage capacity of the battery is not up to the standard. At this time, the maintenance personnel need to inspect each battery to eliminate the damaged battery. 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-ion battery UPS can be at -20- Work normally at 60 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-ion battery UPS power supply, the above-mentioned imbalance due to the changes in the characteristics of each unit battery over time cannot be eliminated by the internal charging circuit of the lithium-ion battery UPS power supply, so this characteristic has occurred If the battery pack is obviously unbalanced, if offline equalization is not taken in time, the unbalance will become more and more serious. 3. Under certain conditions, re-float the lithium-ion 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-ion battery by using the charging circuit in the machine. ～12h or more and then run with load. The UPS power supply has been 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-ion battery to fail 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-ion battery UPS is closely related to the depth of its discharge. The lighter the load carried by the lithium-ion battery UPS power supply, the greater the ratio of the available capacity of the lithium-ion battery to its rated capacity when the mains power supply is interrupted. When the lithium-ion battery UPS power supply is in the mains power supply interruption, and the lithium-ion battery is used to supply power to the inverter, most lithium-ion battery UPS power supplies will ring a periodic alarm with a gap of about 4s to notify the user that it is now Power is supplied by the battery. When the alarm sound becomes rapid, it means that the power supply has been deeply discharged. Emergency treatment should be carried out immediately, and the lithium-ion battery UPS power supply should be turned off. It is not unavoidable. Generally, do not let the lithium-ion battery UPS power supply work until the automatic shutdown due to low battery voltage is over.
