In recent years, the number of DC power system in substation has been increasing. And the technical transformation of DC power system, fault maintenance and other workload is also on the rise, therefore dc emergency power emerged. The lead-acid battery is usually adopted for traditional DC emergency power supply. The disadvantage of lead-acid battery in volume and quality makes it difficult to realize the portability and mobility of dc emergency power. Lithium iron phosphate battery technology is the frontier technology in the rapid development period. However, the characteristics are not studied clearly. This paper studies the characteristics of lithium iron phosphate battery in different ambient temperature, operating conditions, and current of charge and discharge, analyses and summarizes the characteristics of battery charge and discharge, so as to improve the maintenance of station DC power supply system and the reliability of power supply network.
