Abstract
A power supply mat includes a power transmission coil configured to transmit electric power supplied from an external power supply or internal power supply to a moving body provided with a power reception coil by noncontact, a covering sheet configured to cover the power transmission coil, and a light emitting device configured to emit light toward the outside when detecting the moving body is approaching it within a predetermined distance.
Claims8
A power supply mat comprising:
- a power transmission coil configured to transmit electric power supplied from an external power supply or internal power supply to a moving body provided with a power reception coil by noncontact;
- a covering sheet configured to cover the power transmission coil;
- a light emitting device configured to emit light when detecting the moving body is approaching the light emitting device within a predetermined distance;
- and
- a plurality of antennas attached to the covering sheet at different attachment positions, the light emitting device configured to emit light toward a direction of the moving body originating a signal detected based on a difference of reception strengths of the signal received by the antennas or a difference of reception times of the signal received by the antennas.
