Power transmission system and method, power transmitting apparatus and power receiving apparatus |
摘要 |
A power transmission system (1, 2) is provided with a power transmitting apparatus (11, 12, 13) having a power transmission coil (101) and a power receiving apparatus (21, 22) having a power reception coil (201) disposed at a distance from the power transmission coil, and transmits and receives electric power in a wireless manner between the power transmission coil and the power reception coil. The power transmission system is provided with: a foreign body detecting device (106, 206) configured to detect a foreign body positioned in surroundings of the power transmission coil and the power reception coil and detect a relative position of the detected foreign body to the power transmission coil or the power reception coil; and a power controlling device (104) configured to control the power transmitting apparatus to control the transmitted and received electric power according to the detected relative position. |
