METHOD FOR DETERMINING CHARGING PROFILE OF BATTERY AND BATTERY CHARGING SYSTEM USING SAME

A method for determining a charging profile of a battery according to the present disclosure includes determining a reference state of charge (SOC) corresponding to a lithium deposition boundary potential using a test cell, determining a first charging profile by performing constant current (CC) charging on the test cell until the reference SOC and performing constant voltage (CV) charging constantly maintaining a voltage between a negative terminal and a positive terminal after the reference SOC, determining a second charging profile by performing CC charging on the test cell until the reference SOC and performing CV charging constantly maintaining a voltage between the negative electrode surface and the positive terminal after the reference SOC, and correcting a third charging profile obtained from a battery including a plurality of cells using a difference between the first charging profile and the second charging profile.
