Abstract
Provided is a non-destructive method for detecting lithium plating by which lithium plating can be detected in real time in an actual use environment of a secondary battery, a secondary battery charging method and apparatus for charging a secondary battery under the condition in which lithium plating does not occur by using this method, and a secondary battery system for detecting the state of a secondary battery by using this method. The method for detecting lithium plating according to the present disclosure is a method which detects lithium plating in a negative electrode in real time by observing a change in battery voltage as a function of SOC during charging a secondary battery, and determines a point at which a rise speed of the battery voltage slows down as a lithium plating occurrence point.
