Abstract
A wireless power transmission system transmits power from a power transmitting apparatus to a relay power receiving apparatus by applying voltage to an active electrode in the power transmitting apparatus, which is opposed to an active electrode in the relay power receiving apparatus, and a passive electrode in the power transmitting apparatus, which is opposed to a passive electrode in the relay power receiving apparatus.
