A Study on the Hybrid System of Intelligent Lithium Iron Phosphate Battery Based on Economic Communication Power Model

Aiming at the problem of high replacement and maintenance cost of communication power battery, this paper studies the intelligent lithium iron phosphate battery hybrid system. The economic requirements of communication power supply are fully considered. For the problems of battery aging and insufficient charge and discharge in the use of communication power supply batteries, the battery management system of lead-acid battery and lithium iron phosphate battery is studied. Through system optimization and software and hardware design, the service life of the battery can be effectively increased by about 33%. The test results show that the hybrid system can effectively improve the service efficiency of the battery, make its charge and discharge more fully, and avoid the aging problem caused by system isolation. The experiments of voltage test, state of charge estimation and equalization test show that the system has good effect. In terms of economy, the intelligent lithium iron phosphate battery hybrid system can effectively save about 43.3 % of the construction cost of the network base station, which has a good application prospect.
