Abstract
A charging circuit may include a battery unit in which a rechargeable battery is mounted; a charging unit configured to provide a charging current to the rechargeable battery in the battery unit, based on a direct current (DC) voltage converted from an alternating current (AC) voltage, and configured to charge the rechargeable battery; and/or a controller configured to control the charging unit such that the charging unit provides the rechargeable battery with a first charging current following a first current profile in a first charging mode as the charging current at least in a first period of the first charging mode, based on the charging current, a battery voltage of the rechargeable battery, and a temperature of the rechargeable battery, wherein the first current profile is smaller than an available maximum current in the first period.
