Abstract
Provided are a lithium plating detection method, a battery management method and apparatus for safety diagnosis using the lithium plating detection method. The lithium plating detection method according to the present disclosure includes detecting, accumulating and tracking each of an open circuit voltage (OCV) after fully charging and an OCV after fully discharging of a battery every charge/discharge cycle of the battery, and determining if lithium plating took place in the battery using a result of tracking the OCV after fully charging and the OCV after fully discharging, wherein a range satisfying a condition of the reduced OCV after fully charging and the reduced OCV after fully discharging in the tracking result is determined as a range in which lithium plating starts to take place.
