Abstract ESS is expanding with the spread of renewable energy, but fire and explosion accidents may occur due to fault. Therefore, predictive maintenance technology for efficiency and safety is becoming more important. In this paper, for predictive maintenance of lithium-ion batteries, empirical data for battery were analyzed and the time of fault was predicted using the cell voltage deviation.
