NON-CONTACT ELECTRIC POWER TRANSFER DEVICE, NON-CONTACT ELECTRIC POWER RECEPTION DEVICE, AND NON-CONTACT ELECTRIC POWER RECEPTION SYSTEM

摘要

A contactless power transmitting device is capable of contactlessly transmitting power to a power receiving device (100). The contactless power transmitting device includes a power transmitting unit (220) configured to be capable of contactlessly transmitting power to the power receiving device, and a communication unit (230) that sends information, which relates to a magnetic flux distribution of the power transmitting unit during power transmission, to the power receiving device. The information is preferably used to determine whether or not the power receiving device (100) is to receive electric power from the contactless power transmitting device (200). It is more preferred the communication unit (230) transmit the information before the power transmitting unit (220) starts transmitting power to the power receiving device (100).
