With the development of communication technology, operators require the equipment to be integrated, miniaturized, light-weight and highly reliable. The 48V lithium iron battery module is the best choice for communication backup power supply, which is in line with the development trend of communication equipment and depends on its own many outstanding characteristics.

Introduction to communication lithium battery

Lithium iron phosphate battery, as a backup power supply for small and distributed equipment in the communication field, has formed a mature market segment. The communication iron lithium battery system is the first high-tech product successfully developed in China, with independent intellectual property rights. The products fill the domestic gap, and the main technical indicators are at the international leading level;

The communication lithium battery system is the only new type of backup power supply system produced in batch and widely used in the communication field in China. It has been used in the market for the longest time with the largest number, and has received a good market response. In order to meet the needs of the communication industry, there are two important types of lithium iron phosphate battery products: 12V and 48V modules, with capacity classes of 10Ah, 20Ah, 50Ah, 150Ah, 200Ah, etc.

Through series and parallel connection, the battery modules can be formed into lithium battery packs with various voltage levels and capacities to meet various requirements of switching power supply and UPS backup. Lithium iron phosphate battery for communication generally adopts modular structure. A 48V/50Ah battery pack module is generally composed of 15 or 16 50Ah battery cells in series.

Features of 48V Tongxin Lithium Battery Pack

1. Ultra long service life, the capacity of 1000 cycles shall not be less than 70%;

2. Excellent operating temperature. The ambient operating temperature of the 48V communication lithium battery pack can reach - 20~+60 ℃ (recommended operating temperature; - 15~+50 ℃), greatly reducing the cost of equipment purchase and power consumption;

3. The battery detection unit installed in the 48V lithium battery pack can accurately detect the battery voltage, temperature, capacity and other conditions in real time, and timely transmit them to the UAV through the communication system, which can fully improve the safety of the product;

4. The battery shell is designed with alloy material, with superior impact resistance, high and low temperature resistance, and effective flame retardancy, which can ensure that the lithium battery pack always maintains effective protection capability under the impact of external forces. The external folding handle is convenient for handling;

5. The lithium battery pack for 48V communication base station has the functions of providing overcharge, over discharge, overcurrent, over temperature and short circuit protection, providing voltage equalization during charging, displaying system operation status and fault alarm, setting the address of master and slave computers, system reset, SOC display, etc. At the same time, it can collect the information of all battery packs, realize multi computer parallel connection through RS485, communicate with the upper computer through RS232 communication interface, and receive corresponding instructions, Set parameters and monitor data, and adjust charge and discharge control according to battery status;

6. The iron lithium single battery adopts a fully sealed structure. The battery can be placed at will, without harmful gas emission, safe and pollution-free. It is a green environmental protection product.
