Analysis of the use of integrated lithium iron batteries in outdoor communication stations

At present, the lithium iron phosphate battery technology of the IBS mode is relatively mature, and the conventionally used single-group battery capacity has 10Ah, 20Ah, 30Ah, 50Ah, as a replacement and supplement for lead-acid batteries. According to the characteristics of high temperature resistance and high rate discharge of iron-lithium batteries, it is important to use them in harsh environments such as indoor distribution, WLAN, and outdoor cabinet stations. Among them, due to the large environmental temperature difference at four o'clock in a year for outdoor cabinet sites, especially the high temperature in summer, frequent thefts and other reasons, the existing network backup power supply of this type of site is severely guaranteed and the cost is high. The outdoor cabinets in the area adopt ventilation or heat exchange methods. The temperature in the high-temperature battery cabinets in summer can be as high as 55°C, and a few cabinets are even higher. Generally, lead-acid batteries are replaced in two years. At the end of 2012, the outdoor base station of Qiantang Travel Company used a 150Ah integrated lithium iron phosphate battery to replace the original 200Ah lead-acid battery as a pilot. After two years of testing, the performance of the iron-lithium battery is still good. Calculated on the basis of the province's centralized procurement price this year, the price of the 150Ah iron-lithium battery is 11,400 yuan, and the original brand 200Ah lead-acid battery is 5,040 yuan per group. The iron-lithium battery has a warranty period of 6 years. The lead-acid battery needs to be replaced within 6 years, and the total cost is 15,120 yuan, which does not consider the replacement and logistics costs. In addition, the stolen rate of lead-acid batteries in outdoor stations is very high. Because iron-lithium batteries are a new product, the recognition rate is low, and there is no channel for stolen goods, so the stolen rate is very low. In the medium and long term, the promotion of the use of integrated lithium iron phosphate batteries in outdoor stations can reduce costs and increase efficiency. Through exchanges, it is known that similar situations exist in other areas of the province. It can be seen that the demand for replacing lead-acid batteries with lithium iron phosphate batteries in outdoor stations is particularly urgent. 3. Lithium iron phosphate batteries are mainly used in the communication industry as follows: (a) outdoor base stations; (b) non-air-conditioned base stations such as village communication; (c) indoor macro base stations with tight space; (d) DC power supply Indoor overturning/distributed source stations; (e) solar photovoltaic base stations in areas without mains or three or four types of mains; (f) WLAN sites with DC power supply. Regarding the communications industry, we must pay close attention to the three advantages of lithium iron phosphate batteries, which reflect energy conservation and emission reduction from the perspectives of energy saving, land saving, and material saving. Lithium iron phosphate power lithium-ion battery packs are new in the mobile communications industry, but they are being piloted. When verifying the new product, it has been unanimously recognized by various experts and scholars. With the strong support and promotion of the government, lithium iron phosphate batteries will be used more widely.
