A power transmitting device includes a power transmitting coil for providing output power to a power receiving coil, a thermal sensor that detects a temperature around the power transmitting coil, and a power transmission control circuit that controls the power transmitting device. The power transmission control circuit performs operations including: causing the power transmitting coil to provide first output power, causing the power transmitting coil to provide second output power to the power receiving coil for charging a battery connected to the power receiving coil, causing, if the detected temperature is equal to or higher than a threshold due to a presence of a metal foreign object, the power transmitting coil to reduce a level of the output power or stop the output power, and outputting a first signal indicating whether the metal foreign object is detected.
