Abstract

Provided is a device-to-device (D2D)-based wireless power receiving device including an observation part configured to monitor a battery, an estimator configured to estimate usage and a workload of the battery on the basis of a result of monitoring the battery, a mode determiner configured to determine required power of the battery on the basis of the usage and the workload, and determine a reception mode according to the required power, and a power receiver configured to wirelessly receive power from another device according to the reception mode. Accordingly, wireless power charging efficiency can be maximized.

Dependencies are inferred from the claim text.
