What are the reasons for telecom operators to switch to purchasing lithium iron phosphate batteries? Energy storage in the market is where lithium iron phosphate batteries are used. Lithium iron phosphate batteries are being used more and more widely due to their outstanding safety performance and low cost. The upgrading of communication technology is giving birth to new application markets for lithium batteries, and lead-acid batteries are gradually being replaced by lithium batteries.

What are the reasons for telecom operators to switch to purchasing lithium iron phosphate batteries?

It is understood that at present, the three major domestic communication operators China Telecom, China Mobile, China Unicom and other communication operators have adopted lithium iron phosphate batteries that are more environmentally friendly, more stable, and have a longer service life to replace the previous lead-acid batteries. Lead-acid batteries have been used in the communication industry for nearly 25 years, and their disadvantages are becoming more and more obvious, especially for the computer room environment and post-maintenance.

Among the three major operators, China Mobile uses relatively more lithium iron phosphate batteries, while China Telecom and China Unicom are more cautious. The main reason affecting the large-scale use of lithium iron phosphate batteries is the high price. Since 2020, China Tower has also requested the purchase of lithium iron phosphate batteries in multiple tenders.

Compared with lead-acid batteries, lithium iron phosphate batteries for communication power supplies have the advantages of small footprint, high energy density, long cycle life, safety, reliability, and environmental protection. Lithium iron phosphate batteries are gradually entering people’s field of vision.

1. In terms of energy saving, a communication base station using lithium batteries can save 7,200 degrees of electricity a year, and the three major operators have 90,000 communication base stations in a province, so power saving cannot be underestimated. In terms of environmental protection, lithium batteries have no heavy metals and have little impact on the environment.

2. In terms of cycle life, the cycle life of lead-acid batteries is generally about 300 times, the cycle life of lithium iron phosphate batteries exceeds 3000 times, the cycle life of lithium batteries can reach more than 2000 times, and the service life can reach more than 6 years.

3. In terms of volume, due to the light weight of the lithium battery pack, the installation of lithium iron batteries in the newly rented computer room site can basically meet the load-bearing requirements without reinforcement, saving related construction costs and shortening the construction period.

4. In terms of temperature range, lithium iron phosphate batteries are resistant to high temperatures, and the working temperature can range from 0 to 40. Therefore, for some macro stations, the battery can be directly placed outdoors, which saves the objective cost of building (renting) houses and the cost of purchasing and operating air conditioners.

5. In terms of safety, the communication base station energy storage lithium battery management system BMS has the characteristics of advanced communication functions, perfect system self-inspection, high reliability, high safety, strong electronic control, strict standards, and strong adaptability.

Application Scenarios of Lithium Iron Phosphate Batteries for Communication

It is used for macro base stations, with poor bearing performance and narrow area.

Due to the light weight and small size of the lithium iron phosphate battery, if it is applied to the base station, it can be directly applied to the base station with poor bearing performance of the macro base station or the area with tight space in the city center, which will undoubtedly reduce the difficulty of site selection and make the site selection work efficient. Lay the foundation for the next step. It is used for base stations with frequent power outages and poor mains power quality.

Since the lithium iron phosphate battery has the characteristics of long service life and many charge and discharge cycles, it can be used in base stations with frequent hotels and poor mains power quality, giving full play to its advantages and highlighting its characteristics, so as to ensure its own operating performance.

Wall power supply suitable for indoor distributed base stations.

The lithium iron phosphate battery has the characteristics of light weight and small size, and can be used as a backup battery to strengthen the switching power supply to ensure timely power supply, reliability and safety of power supply.

Applied to outdoor integrated base stations.

Many base stations adopt the outdoor integrated base station management mode, which solves the problem of difficulty in renting computer rooms. Outdoor integrated base stations are easily affected by various external factors, such as temperature, humidity and windy weather. In this harsh environment, lithium iron phosphate batteries can effectively guarantee the charge and discharge performance at high temperatures. Even if there is no air conditioner as a guarantee, the lithium iron phosphate battery can operate normally, avoiding the damage caused by high temperature.

Summary: Lithium iron phosphate battery is the development trend in the communication field. Lithium iron phosphate battery has been piloted by many communication operators, and it is also a popular technology in the field of communication power supply.
