Title:
MISALIGNMENT DETECTION DEVICE AND COIL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/070945
Kind Code:
A1
Abstract:
This misalignment detection device is provided with: a plurality of coils which receive magnetic force lines generated by a power transmission coil and are disposed side by side line-symmetrically with respect to an axis line as a symmetrical axis; a plurality of temperature sensors which are respectively disposed adjacent to the plurality of coils and output temperatures; and a processing device for detecting misalignment of a power receiving coil with respect to the power transmission coil along the axis line on the basis of a difference value for evaluating a difference between the temperatures. With this misalignment detection device, it is possible to perform a misalignment detection which is not susceptible to the surrounding environment.
