Abstract
Provided are a battery management system and a battery management method using the same. According to the present invention, it is possible to select high-risk battery cells that are highly likely to be out of an operating voltage range by applying a change amount according to SoH for each of the battery cells to each SoC for each of the battery cells, and calculate the representative SoH of the battery pack based on the selected high-risk battery cells, and then calculate the actual usable capacity of the battery pack.
