What are the characteristics of the backup iron-lithium battery system for communication? The battery pack of the communication power supply is a backup energy storage device, which is the key to ensure the operation of the entire system after a power failure. The communication industry system adopts the environmentally friendly Lifepo4 Battery, and is equipped with a high-performance BMS to effectively manage the battery cells. Compared with traditional batteries, it has a wider range of performance and application advantages.
The backup iron-lithium battery system for communication is one of the high-tech products developed by Suneng Electric. The Lifepo4 Battery system has many features such as integration, miniaturization, light weight, intelligence, centralized monitoring, management and maintenance, unattended operation, convenient use of standardized cabinet installation, energy saving and environmental protection. The nominal voltage of the backup Lifepo4 Battery system is 48V and the nominal capacity is 50Ah.
The AC-DC integrated 48VLifepo4 Battery communication power supply system includes the 48VLifepo4 Battery group module housed in the chassis, which provides 48V DC output when the mains is powered off; the inverter module, which is connected to the battery pack module, when the mains is powered off When converting 48V DC to 220V AC output; and switching power supply module.
The switching power supply module includes a modular battery management system, which is used to manage the charging and discharging of the battery pack module; and a rectifier module, which is connected to the battery pack module to provide constant current by rectifying the mains input when the mains is normal. output, and the battery module is charged when the battery capacity of the battery module decreases.
As a backup power supply, Lifepo4 Battery is widely used in communication fields such as access network equipment, remote switching offices, mobile communication equipment, transmission equipment, satellite ground stations and microwave communication equipment, which fully satisfies the rapid development of the communication industry. It presents new challenges and is favored by the communications industry.
The Lifepo4 Battery system for communication is mainly used in backup power supply and UPS uninterruptible power supply in the communication industry; its performance meets the requirements of the communication standard technical report "Backup Lithium-ion Battery Pack for Communication". The battery structure meets the higher new requirements of the telecommunications industry for the backup power supply for communications.
The advantages of Lifepo4 Battery for communication and traditional lead-acid battery
① Flexible configuration: Multiple iron-lithium battery modules are used in parallel, making it possible for large-capacity communication lithium battery systems to be put into practical applications, which not only improves the output power of the system, but also prolongs the backup time of the system;
②Strong safety: The positive electrode material of Lifepo4 Battery has good electrochemical performance, the charging and discharging platform is very stable, the structure is stable during the charging and discharging process, the battery does not burn, does not explode, and has good safety;
③Good high temperature performance: the battery works normally when the external temperature is 55℃;
④High power output: the standard discharge is 0.2C, and it can be charged and discharged at 3C;
⑤Long cycle life: charge and discharge at 1C at room temperature, the capacity of the monomer is still greater than 80% after 2000 cycles;
⑥Environmental protection: the whole production process is clean and non-toxic, and all raw materials are non-toxic;
⑦High discharge rate: Fe-lithium batteries have very superior rate discharge performance, and lower-capacity Fe-lithium battery systems can be used to meet high-current discharge applications;
⑧ Small size and light weight: high volume specific energy and weight specific energy, no special requirements for space and load-bearing during installation, which greatly reduces the rental cost of the site.
The future application direction of Lifepo4 Battery system in the communication industry
Regarding the use of IDC computer room, traditionally we use lead-acid batteries that cover a wide area and have high floor bearing requirements, but our new distributed lithium battery IDC computer room has many different usage models.
Integrated power supply: Lifepo4 Battery can cooperate with UPS and network accessories rack to form a systematic power supply. All functions are integrated in one power cabinet. We will also provide integrated solutions for environments with relatively harsh indoor coverage, mainly in the form of outdoor corridors, pole installations, wall hangings and roofs.
Echelon utilization, we know that with the development of automobile use, there will be more and more batteries that are eliminated from automobile use. If these batteries are all buried in place, it will be particularly detrimental to environmental protection. The remaining 80% of the capacity, in the communication industry, especially as a backup state, actually has no effect on the use of this kind of battery.
At present, the national policy strongly supports the electric vehicle industry, which has promoted the rapid improvement of lithium battery-related processes, and the price of lithium batteries has also dropped rapidly. Perhaps in the near future, the more cost-effective Lifepo4 Battery will become a vital force in the huge market of the communication industry.
Summary: The Lifepo4 Battery system has many advantages such as small size, light weight, excellent cycle performance, high-rate charging and discharging, green environmental protection, etc. Many industry insiders predict that it is expected to become the next mainstream of many types of communication main equipment, auxiliary equipment, etc. Power configuration.
