Title:
CHARGING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/016163
Kind Code:
A1
Abstract:
Disclosed are a charging method and apparatus, which belong to the technical field of electronics. The method comprises: establishing a connection between a first electronic device and a second electronic device; based on the connection, the second electronic device acquiring real-time charging voltage information about the first electronic device; and during the process of the second electronic device charging the first electronic device, according to the real-time charging voltage information about the first electronic device, controlling the second electronic device to output a charging voltage to the first electronic device, so as to charge the first electronic device. By adopting such a charging method, in a charging process, voltage conversion is performed in a second electronic device only once. Compared with the charging method in which the first electronic device and the second electronic device both need to perform voltage conversion, this charging method reduces the voltage conversion process performed in the first electronic device, thereby reducing electrical energy wastage caused by the voltage conversion process, and improving charging efficiency.
