Abstract
A charging control device includes: a battery state detector configured to detect a cell voltage of at least one cell of a battery and a charging current between the battery and a charging device; and a controller configured to perform a cell over voltage protection (COVP) function on the battery based on a cell over voltage protection voltage, and to vary the cell over voltage protection voltage in response to the charging current.
