Why do you say the lithium iron phosphate battery is the most ideal choice for machineroomless base station?

Source: 2020 - 04 - 14 19:57 hits: lithium iron phosphate battery is the most ideal choice for base station machineroomless base station no room is refers to the base station and the connection between the base station computer room and transmission network, it is composed of integrated outdoor cabinet with built-in distributed equipment main equipment and auxiliary equipment of the construction of the macro station machineroomless base station with the real structure of integration, low power consumption, stable and reliable, strong adaptability, easy operation and maintenance, outdoor networking way agile diversity, etc. Don't need to construction equipment room, power supply, air conditioning and other supporting facilities, reduce the supporting infrastructure investment, reduce the operational cost in the late. At the same time, because the installation of the base station is convenient, can shorten the construction period, to achieve the rapid construction of the base station. Because there is no room for base station cabinet high integration, the integration of outdoor integration equipment within the cabinet must therefore miniaturization, modularization. Traditional valve control type lead acid battery for large volume, high temperature requirements, in the absence of room, can't meet the demand of base station of standby power. Put forward a kind of advanced performance of battery acid lithium iron batteries, battery back-up as a miniature of the base station. Battery has small volume, light weight, excellent high temperature performance, excellent cycle performance, charge and discharge rate is high, the green environmental protection, etc. , can be used in harsh environment temperature is high, the base station area of little space room and small load, and so on, can meet the demand of backup power of base station computer room. Lithium iron phosphate battery mainly consists of the positive and negative, electrolyte and diaphragm. Are extremely lithium iron phosphate ( Abbreviation of LiFePO4, namely the lithium iron phosphate) 。 The anode is graphite or coke. Six characteristics of lithium iron phosphate battery pack ( 1) High flow when the test temperature is 25 ℃, the test voltage is 2. 9 ~ 3. 3 v, lithium iron phosphate battery discharge curve in different time as shown. Can be seen from the diagram, under different test voltage and ratio, when the discharge voltage close to 2. 0 v, the discharge capacity is close to 100%. ( 2) High energy density lithium ion battery energy density of 150 wh/kg. Under the same volume, the lithium ion battery energy density of about three to four times that of lead-acid batteries. Compared with lead-acid batteries, lithium iron phosphate batteries of the same capacity weight reduce about 60% ~ 70%. Lithium iron batteries with lead-acid batteries energy for such as shown in table 1. ( 3) High cycle performance under normal circumstances, the ordinary lead-acid battery charge and discharge cycle is 300 ~ 500 times, lithium ion battery charge and discharge cycle can be more than 1000 times. ( 4) Quick charge high energy conversion efficiency, can be in 1 ~ 3 hours to recharge, and ordinary lead-acid batteries slower. ( 5) High security because ordinary lead-acid batteries contain heavy metals such as lead, antimony, easy to cause serious pollution to the environment, use and maintenance easy to leak, if internal overflow cause equipment corrosion, sulfate personnel injury accident, and lithium iron phosphate batteries do not contain any harmful heavy metal elements, no pollution, high safety, is the safety of the lithium ion battery. ( 6) Low cost of traditional 48 v lead-acid battery service life for 5 years, and the service life of the communication of lithium iron batteries can be up to 10 years. In addition, the lithium iron phosphate battery using intelligent intermittent charging and discharging management mode, greatly reduces the power consumption cost.
