Abstract

A power transfer system, including a vehicle (10) and a power transmitting device (90), and the power transmitting device (90) are provided. The power transmitting device (90) is configured to contactlessly transmit electric power to a vehicle on which a power receiving coil having any one of a plurality of different coil types is mounted. The power transmitting device (90) includes a plurality of power transmitting coils and an electronic control unit (ECU (800)). The ECU (800) is configured to control currents that are respectively supplied to the plurality of power transmitting coils. The ECU (800) is configured to select at least two power transmitting coils from among the plurality of power transmitting coils based on the coil type of the vehicle that serves as a power transmitted target and to set directions of currents respectively flowing through the selected at least two power transmitting coils.

Description

technical field [0001] The present invention relates to a power transmission device and a power transmission system. Background technique [0002] International patent application publication number WO2011 / 016736 describes various coil shapes for use in a contactless charging system that transfers power contactlessly. When a power receiving coil for non-contact charging is mounted on a vehicle, it is assumed that these various coils are mounted. [0003] In non-contact charging, it is important to align the position of the power transmitting coil with the position of the power receiving coil to increase transmission efficiency. However, the power transmitting device is not easily adapted to vehicles on which power receiving coils having various coil shapes are respectively mounted. Even if the coil shapes of the respective power receiving coils of the vehicle are the same, the mounting positions of the power receiving coils may differ from each other. If the shape of the ...
