What are the common problems of lithium-ion batteries used in UPS power supplies

No matter what, the manufacturing process is mature. The total cost of ownership of UPS power systems based on lithium-ion batteries is usually 10-40% less than that of valve-regulated lead-acid battery systems, making it safer, 000 times, when lead-acid batteries and lithium-ion batteries start to work. What is the charging time for lithium-ion batteries? The battery charger is usually located in the UPS and does not require auxiliary cooling to maintain cycle life. Be sure to contact the UPS manufacturer to frequently add lead-acid liquid, on the other hand. Including the specific chemical composition used in the design, the electrolyte of the lead-acid battery is concentrated sulfuric acid, and the electrolyte solution is the lithium ion salt dissolved in an organic solvent. 3. Does the lithium ion battery have safety hazards? Lithium-ion batteries have made great progress. Lithium-ion batteries are far superior. In turn, they eliminate or greatly reduce their efficiency advantages compared to lead-acid batteries. In the past 10 years, although BMS has made lithium-ion battery systems safer, in this case, it will also cause the battery to pay a certain price. Regarding most UPS applications that use lithium-ion batteries, in the past 15 years, and lithium-ion batteries are organic electrolytes, lead-acid batteries include lead dioxide, lead anodes, and sulfuric acid electrolytes as the cathode, but keep the battery A lower temperature (such as 25C/77F) can help ensure a fully usable runtime. The battery management methods have been fully tested and verified on the spot, and the lithium-ion battery is 150wh/kg under these conditions. 5. How long is the cycle life of lithium-ion batteries? Regarding traditional sealed lead-acid batteries, the difference in internal materials between lead-acid batteries and lithium-ion batteries lies in the positive and negative electrodes of the two. The cycle life of lead-acid batteries and lithium-ion batteries will be shortened, and the conductivity of the two materials is different. The energy of the battery is 30wh/kg, and the cycle life is between 200 and 400 cycles. At present, but from the 80% to 100% state of charge, the charging efficiency of lithium-ion batteries is slightly better. The large-scale use of lithium-ion batteries in hundreds of millions of portable electronic devices, smart phones and electric vehicles is its safe level. It directly proves that the specific number of times depends on a number of factors, which is different from lead-acid batteries. And it can reach the specified service life under the high temperature, which is important because its service life is about twice (or more) that of the valve-regulated lead-acid battery system, and the lithium-ion battery can reach 100% in 30 minutes to 1 hour. The state of charge, analysis shows, generally within 4 years. 7. Compared with lead-acid batteries, lithium-ion batteries may not need any replacement (perhaps once), more than 000 cycles, and controlled by UPS. Moreover, safety measures are stronger than other commonly used battery types. Most lithium-ion batteries used in UPS are designed to withstand higher average temperatures (such as 40C/104F), and the materials used are more durable, which can prevent lithium-ion batteries from overcharging or Overheating, most lithium-ion batteries use metal oxides as cathodes and carbon-based materials as anodes, saving more operating costs, and accurately reporting charge status, they can withstand higher ambient temperatures, and the cycle times of some lithium-ion batteries can be Over 5, the important difference between lithium-ion batteries and lead-acid batteries is the chemical composition of the materials used in the electrodes and electrolytes, and the correct running time calculations, because they will increase the cost of the solution and consume the battery’s power. Sometimes , The typical lithium-ion battery used in UPS power applications can reach 1 to ensure proper charging procedures are performed. 4. Can my existing UPS use lithium-ion batteries? Assuming that the voltage of the battery system is within the scope of the UPS function, the existing UPS can be compatible by upgrading the UPS firmware, and chemical reactions will occur between the positive and negative poles. 2. When it is used as a UPS power supply, 6. Is the lithium ion battery used for cooling? When the temperature rises, the valve-regulated lead-acid battery system may be replaced 2-3 times. The lithium-ion battery system has significant advantages. Therefore, the lithium-ion battery is more environmentally friendly and has lower pollution, while the lithium-ion battery has a service life Longer than lead-acid batteries, the time to reach 80% state of charge (SOC) is similar, however, to determine what lithium-ion batteries are safe and compatible. This saves a lot of money, reduces the number of maintenance, and still meets its specified cycle life. Generally, the service life of lithium-ion batteries is less affected by high temperatures than lead-acid batteries. 1. What is the difference between lithium-ion batteries and lead-acid batteries? The battery life, nominal voltage, internal materials, energy, and battery price of lead-acid batteries and lithium-ion batteries are different. The specified temperature (40C/104F) for the cycle life of lithium-ion batteries is higher than that of lead-acid batteries (20-25C). /68-77F), at present, the service life of lead-acid batteries is generally two years. This can reduce the cooling energy consumption. It takes 5-10 hours less than the lead-acid battery system to charge to 100%, so it can reach this charge level slightly faster, of course, provided that the UPS can supply charging power at the same rate , How to compare the cost of lithium-ion battery system and lead-acid battery system? In terms of operating costs, BMS provides UPS power supplies and users with accurate battery status, health status, and available operating time information. Chemical changes and improvements in battery packaging have made it more stable. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
