A foreign object detection device includes a processor, a detecting circuit assembly connected to the processor, a coil connected to the detecting circuit assembly, a signal generator connected to the processor and the detecting circuit assembly, and a coil configuring circuit connected to the processor and the coil. The processor outputs a control signal to the coil configuring circuit so as to control the coil configuring circuit to generate a switch signal for enabling the coil to switch to one of a closed mode and an open mode, and controls the signal generator to transmit a test signal to the coil via the detecting circuit assembly when the coil is controlled to switch to the open mode.
