Analysis of overcharging characteristics of a new type lithium iron phosphate battery for dc system of substation

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