摘要： A communication control device comprises: an antenna; and a control unit that controls wireless communication related to wireless power transfer to a power receiver device through a power transmitter device. The control unit acquires via the antenna a radio wave status of each of a plurality of channels related to the wireless communication. The control unit acquires a power transmission status of the wireless power transfer. The control unit sets, based on the acquired power transmission status, switching conditions for switching the channel according to the radio wave status. The control unit causes the channel to be switched based on the radio wave status and the switching conditions. The control unit causes the wireless communication to continue on the switched channel.

摘要： This misalignment detection device is provided with: a plurality of coils which receive lines of magnetic force generated by a power transmitting 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 disposed adjacent to each of the plurality of coils and output temperatures; and a processing device for detecting misalignment of a power receiving coil with respect to the power transmitting coil along the axis line on the basis of a difference for evaluating a difference between the temperatures. With this misalignment detection device, it is possible to perform positional misalignment detection which is not easily affected by surroundings.
