Abstract

Provided are a method of predicting a battery charge limit not to cause lithium (Li)-plating, and a battery charging method and apparatus capable of quickly charging a battery based on the battery charge limit. A battery charge limit prediction method according to the present disclosure includes (a) fabricating a three-electrode cell including a unit cell and a reference electrode, (b) measuring a negative electrode potential (CCV) based on a state of charge (SOC) while charging the three-electrode cell, and (c) determining a point at which the negative electrode potential is not dropped but starts to be constant, as a lithium (Li)-plating occurrence point, and setting the Li-plating occurrence point as a charge limit.
