Abstract:
1. An apparatus for controlling charging of a secondary battery, the apparatus comprising: a receiving unit configured to receive a full-charge time of the secondary battery from a user terminal; a sensing unit configured to monitor a charging state of the secondary battery; and a charging controller configured to control charging of the secondary battery according to the full-charge time and the charging state; a remaining time calculator configured to calculate a remaining time as a time remaining from when the full-charge time is received to the full-charge time; and a full-charge time calculator configured to calculate a time to full of the secondary battery according to the charging state of the secondary battery and an intensity of a current applied to the secondary battery, wherein the charging controller is configured to control the current applied to the secondary battery so that the charging of the secondary battery is completed at the full-charge time, wherein, when an external power source is not coupled to the user terminal when the full-charge time is received, the remaining time calculator is configured to calculate the remaining time as a time remaining from when the external power source is coupled to the user terminal to the full-charge time, wherein, when a difference between the remaining time and the time to full is less than a set value, the charging controller is configured to supply the current to the secondary battery, and wherein, when a difference between the remaining time and the time to full is greater than a set value, the charging controller is configured to supply the current to the secondary battery after a time corresponding to the difference between the remaining time and the time to full elapses.
