Electronic device and method for wired and wireless charging in electronic device

A portable terminal comprising:

• a battery;
• a power management circuit electrically connected to the battery;
• a coil;
• a communication circuit electrically connected with the coil;
• a wireless charging circuit electrically connected with the coil;
• and
• a controller operatively connected with the power management circuit, the communication circuit and the wireless charging circuit, the controller configured to:
• identify whether the portable terminal is set to function as a wireless power transmitter or as a wireless power receiver;
• based at least in part on the portable terminal being set to function as the wireless power receiver, control the wireless charging circuit to receive a first wireless power signal from a first external electronic device through the coil, control the power management circuit to charge the battery using the first wireless power signal received from the first external electronic device, and control the communication circuit to transmit, through the coil, to the first external electronic device a first parameter corresponding to a wireless power receiver function;
• and
• based at least in part on the portable terminal being set to function as the wireless power transmitter, control the wireless charging circuit to transmit a second wireless power signal to the first external electronic device or a second external electronic device through the coil, control the power management circuit to supply power to the wireless charging circuit, and control the communication circuit to transmit, through the coil, to the first external electronic device or the second external electronic device a second parameter corresponding to a wireless power transmitter function, wherein the wireless charging circuit is configured to:
• modulate, using the communication circuit, the first parameter with a first modulation scheme before the first parameter is transmitted to the first external electronic device;
• and
• modulate, using the communication circuit, the second parameter with a second modulation scheme different from the first modulation scheme before the second parameter is transmitted to the first external electronic device or the second external electronic device.
