The majority of lithium batteries used in communication base stations are 48V lithium iron phosphate?

　　With the arrival of the information age, people around use mobile phones more and more frequently, and communication base stations are particularly important for people. As the backup power supply of communication base station, 48V lithium ion battery is the reliable guarantee of energy storage power supply. At present, most of the lithium-ion batteries used in the field of communication standby power supply are lithium iron phosphate batteries, and a few are ternary lithium-ion batteries. The cycle life, high temperature characteristics, charge discharge rate function and energy density of lithium ion battery are very good. Many companies use the original 48V lithium iron phosphate battery for communication base station operation.

　　This paper discusses the use of lithium ion batteries with us. Communication base station: that is, mobile communication base station sharing is a way of radio station, which refers to the transceiver that carries information in the limited radio masking area between the mobile communication switching center and the mobile phone terminal. The production of mobile communication base stations has become an indispensable part of China's communication industry. Application of 48V lithium ion battery in communication base station: The outdoor base station of Qiantangjiang Tourism Company adopts 150Ah integrated lithium iron phosphate battery as a pilot to replace the original 200ah lead acid battery.

　　After two years of testing, the performance of lithium iron battery is still excellent. According to the provincial collective purchase price this year, the price of 150Ah iron lithium ion battery is 11400 yuan, and the original brand price of 200ah lead-acid battery is 5040 yuan. However, the warranty period of iron lithium ion battery is 6 years. The calculated cost of replacing three groups of lead-acid batteries within six years is 15120 yuan, and the replacement and logistics costs are not considered during this period. The theft rate of lead-acid batteries in other outdoor stations is very high. As the iron lithium ion battery is a new product, the external recognition rate is very low, and the stolen goods cannot be sold temporarily, so the theft rate is very low. In the medium and long term, the application of lithium iron phosphate integrated battery in outdoor communication base stations can reduce costs and improve efficiency. Through exchanges, similar situations also exist in other regions 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 strong.

　　1、 The application of lithium iron phosphate battery in communication business is as follows:

　　(a) Outdoor base station;

　　(b) Base stations without air conditioning, such as rural communications;

　　(c) Large indoor radio station with narrow space;

　　(d) Indoor covered distributed DC power station;

　　(e) Solar photovoltaic power generation base stations in areas without mains power or three or four kinds of mains power;

　　(f) WLAN location of DC power plan, etc.
