5G base stations use the advantages of lithium iron phosphate batteries to 'roll over' lead-acid batteries
. With the conversion of communication base stations from lead storage batteries to echelon lithium iron phosphate batteries, it is difficult for lead-acid storage demand to take advantage of 5G. Compared with echelon lithium iron phosphate batteries, lead-acid batteries have the shortcomings of short service life, low performance, and a large amount of heavy metal lead. Ladder lithium batteries will completely replace lead-acid batteries in areas where battery performance is low, such as base stations and backup power sources. 5G base station application of lithium iron phosphate battery advantages 'rolling' lead-acid batteries With the pilot and commercial use of 5G systems, the large power consumption requirements of 5G equipment will increase the demand for batteries. On the one hand, there is a huge backup power demand for 5G communication base stations, and on the other hand, there are a large number of retired power batteries for automobiles, which makes communication base stations the best application scenario for echelon batteries. batteries are an important part of the power supply of 5G base stations. At present, lead-acid batteries, lithium batteries, smart lithium batteries, and lithium iron phosphate batteries are all candidates for 5G base stations. However, under the promotion of policies and the significant improvement of the advantages of lithium batteries, lead-acid batteries are gradually being eliminated, and batteries used in base stations are gradually being converted to echelon lithium batteries. 5G base station application scenarios, the 'overwhelming' advantage of lithium iron phosphate batteries has always been recognized in the industry. From a technical perspective, lithium iron phosphate batteries have long cycle life, fast charge and discharge speed, and strong high temperature resistance, which can reduce operating costs and improve operating efficiency for 5G base stations. Lithium iron phosphate batteries generally have a cycle life of 3-5 years and charge and discharge times of 500-600 times, while lithium iron phosphate batteries have a cycle life of more than 10 years and charge and discharge times of more than 3000 times. During the full life cycle of the base station, if lead-acid batteries are used, the batteries need to be replaced, while the lithium iron phosphate batteries do not need to be replaced. Although the cost of lithium iron phosphate batteries is 1-2 times higher than that of lead-acid batteries at this stage, the cost of lithium iron phosphate batteries is only 1/3 of that of lead-acid batteries under the service life of a 5000-cycle system. From the perspective of long-term economic benefits, the use cost of lithium iron phosphate batteries is lower. Compared with lead-acid batteries, lithium iron phosphate batteries are also superior in terms of charging and discharging speed. The charging speed of lithium iron phosphate batteries is 10 times that of lead-acid batteries, which will greatly save the charging time of the base station backup power battery. It is understood that as an energy storage battery, lithium iron phosphate batteries can also store electricity during the low valley period at night and release it during peak hours during the day to achieve peak-shaving and valley-filling and further reduce base station electricity costs. The BMS (Battery Management System) of the lithium iron phosphate battery can monitor the entire battery system equipment, and realize the monitoring of the performance of each battery in the backup power supply. The user can easily grasp the remaining power of each battery and the operation of the equipment with a finger. Etc., this is highly consistent with the development trend of 5G base stations. In terms of safety, lithium iron phosphate batteries have a higher degree of temperature out of control, and there are fewer cases of open flame explosions, and their safety and controllability are high, which can ensure the safe operation of 5G base stations. In the future new 5G base station projects, we will continue to encourage the use of lithium iron phosphate batteries as backup power batteries for base stations, and promote the large-scale application of lithium iron phosphate batteries in base stations. good high temperature performance: the existing base station air conditioner is set to 28°C. If it is raised to 35°C, a separate incubator for lead-acid batteries is required. Otherwise, the battery life will be reduced by half for every 10°C increase in temperature. The lithium iron phosphate battery can withstand a high temperature of 55°C, and its life is not affected. The base station temperature setting value can be directly adjusted to achieve energy saving and emission reduction. The installation area is small. Lead-acid batteries need to be installed in single-layer and double-row, the former covers an area of u200bu200b29% of the latter. The same is a 48V/300Ah iron-lithium battery pack and a lead-acid battery pack. Under the same installation method, the former covers an area of u200bu200b59% of the latter, and the former weighs 34% of the latter. Can 5G base stations use ordinary energy storage systems? As we all know, the number of antenna channels and site capacity of 5G equipment have been greatly increased, resulting in an increase in the overall power consumption of the base station, and the power supply and backup of 5G base stations need to be upgraded and expanded. As a key component of the energy storage system, traditional lead-acid batteries are large and heavy, and the limited computer room and site space can no longer accommodate so many batteries. In energy storage systems, it is a general trend to replace lead-acid with lithium batteries that are smaller, lighter, higher energy density, longer life, and better performance. As a key component of the energy storage system, ordinary lithium batteries are only a simple combination of batteries and structural parts, with only simple backup functions, no coordination, no management or rough management, which will cause waste of resources, high evolution costs, and operation and maintenance. Difficulties and other issues, the use of ordinary lithium energy storage systems can not meet the specific needs of the communications industry in the 5G era. Light is that ordinary energy storage systems can no longer meet the new needs of the 5G era. The era calls for smart energy storage systems equipped with smart lithium batteries. In fact, most operators around the world have moved from calling to action, and are actively deploying smart energy storage systems. Smart lithium battery energy storage system, through 'smart peak shiftCharging, as an energy buffer pool, effectively balances the electricity price difference and reduces site electricity costs.
