Research on Anti-Interference Screening of On-line Measurement of Battery Ageing under Smart Grid Big Data

By analyzing the traditional operation and maintenance mode of substation batteries, the paper proposes a new remote online maintenance and management system for batteries based on smart grids, which changes the traditional maintenance method of using discharge load meters to check offline battery discharge packs. Single battery online voltage inspection, internal resistance test, and dynamic equalization, as well as battery pack remote online verification discharge and equalization charging, real-time monitoring of battery aging, promote intelligent, efficient, and unmanned maintenance battery status in substations, Provide strong technical and program guarantees.
