Method and apparatus to charge battery of mobile device

摘要

A charging method and apparatus, the apparatus including: an adaptor to receive power from a predetermined power source and output a first voltage; a narrow voltage direct current (NVDC) charging unit to convert the first voltage into a second voltage, and supply power to a battery and a system terminal of a mobile device; and a control unit to control the NVDC charging unit to adjust a charging current to be supplied to the battery based on a state of the system terminal, wherein the second voltage is lower than the first voltage.

1. A charging apparatus comprising:
an adaptor to receive power from a predetermined power source and output a first voltage; a narrow voltage direct current (NVDC) charging unit to convert the first voltage into a second voltage lower than the first voltage, and supply power to a battery and a system terminal of a mobile device; a control unit to control the NVDC charging unit to adjust a charging current to be supplied to the battery based on a status of the system terminal; and a sensing unit to sense a capacity of the battery, wherein, if the status of the system terminal is in the on status, the control unit to control the NVDC charging unit to adjust the charging current to a first charging current when the capacity of the battery is equal to a previously set capacity of the battery, and adjust the charging current to a second charging current greater than the first charging current when the capacity of the battery is higher than the previously set capacity of the battery.
