Problems solved by technology

[0012] However, in the prior art described above, when it is determined that there is a magnetic foreign object on the primary coil, the operation of the power transmission transformer is stopped. Therefore, when the measured voltage exceeds a predetermined value due to the presence of a magnetic foreign object, for example, the target charging time The problem of not completing the charging

Abstract

A contactless charging system is provided with a transmitter having a primary coil which supplies power through electromagnetic induction, a receiver having a secondary coil which electromagnetically couples to the transmitter and receives power, and a controller which detects the charging efficiency from the primary coil to the secondary coil and varies the current supplied to the primary coil according to the charging efficiency.

Description

technical field [0001] The invention relates to contactless charging systems used eg in electric vehicles. [0002] This application claims priority based on Japanese Patent Application No. 2010-81401 for which it applied to Japan on March 31, 2010, The content is used here. Background technique [0003] For example, as a device for charging a battery mounted on an electric vehicle, a non-contact power transmission device (corresponding to the non-contact charging system in the present invention) is used. Such a non-contact power transmission device has a primary coil and a secondary coil formed of planar planar coils. In addition, the primary coil and the secondary coil are electromagnetically coupled to form a transformer for power transmission. Therefore, the non-contact power transmission device has an advantage that the degree of freedom of position is large when the two planar coils are electromagnetically coupled. [0004] However, when the transformer for power tr...
