Non-contact electric power transmission system and charging station

摘要

When a power supply ECU (800) receives a signal requesting test electric power transmission, the power supply ECU (800) has a plurality of electric power transmission portions (700A, 700B) start transmission of electric power for positioning, and determines an electric power transmission portion with which a vehicle (10) is carrying out positioning based on which of a plurality of detection portions (601A, 601B) has detected effective electric power. The vehicle (10) transmits a first signal to a charging station (90) when positioning is completed. When the power supply ECU (800) receives the first signal and it is determined that the vehicle (10) has stopped at the electric power transmission portion which is the subject of electric power transmission, the power supply ECU (800) has the electric power transmission portion which is the subject of electric power transmission transmit electric power higher than electric power for positioning.
