Therefore, the battery can be protected, the service life of the battery is prolonged, and the phenomenon of overcharge is prevented.

Optionally, after charging, when the electromagnetic wave disappears, the connection switch can be controlled to be disconnected, so that when the first near-field communication antenna is used for the near-field communication function, the intensity of the electromagnetic wave cannot be weakened, and the communication message can be better transmitted to the signal processing circuit.
Optionally, for the case that the first terminal broadcasts the charging completion notification to the outside, the corresponding processing procedure of the second terminal may be as follows: receiving a charging completion notification broadcast by the first terminal through the second near field communication antenna; in response to the charging completion notification, the external emission of the charging electromagnetic wave is terminated.

After receiving the discovery message broadcast by the second terminal, the first terminal can analyze the discovery message to obtain data carried in the discovery message, send the data to the signal processing circuit for processing, generate a confirmation message corresponding to the discovery message through the signal processing circuit, and broadcast the corresponding confirmation message generated by the signal processing circuit to the outside through a first near field communication antenna arranged in the confirmation message, wherein the first terminal can broadcast the corresponding confirmation message to the outside through electromagnetic waves. In this way, the second terminal can receive the confirmation message for further processing.
In implementation, after the first terminal broadcasts the corresponding acknowledgement message, the second terminal may receive the acknowledgement message broadcast by the first terminal through the locally arranged second close-range communication antenna, and trigger the second terminal to pop up a selection interface, where a function list of functions that can be implemented by NFC functions (that is, a function list corresponding to the second close-range communication antenna) may be displayed in the selection interface, where the function list may include a communication function option, a charging function option, etc., and the user may click on the charging function option in the selection interface, and trigger the second terminal to start a corresponding charging application program, and the second terminal may receive a charging start instruction, may be an NFC coil through the second close-range communication antenna therein, continuously transmit a preset electromagnetic wave for charging to the outside, and start charging the first terminal.
