摘要:
A power reception apparatus (250) is installable in a vehicle (200) and configured to receive electric power from a power transmission coil (40) embedded in the ground. The power reception apparatus includes: a relay coil (70) that is arranged on a tired wheel (60), which includes a tire (62) and a wheel (64), and includes a first coil (71) and a second coil (72); a power reception coil (240); and a power reception circuit (230) connected with the power reception coil. The first coil and the second coil are connected with each other by an electrical conductor (73). The first coil is arranged inside the tire. The second coil is arranged at a position such that a distance from a central axis (61) of the tired wheel to the second coil is shorter than a distance from the central axis of the tired wheel to the first coil. The power reception coil is arranged at a position such that when the first coil faces the power transmission coil, the power reception coil faces the second coil.
