Abstract
A power transmission apparatus includes a power transmission device having a power transmission amount detecting unit that transmits power and detects a power transmission amount, a power transmission device communication unit that communicates with a power reception device, and a power transmission device controller that calculates power transmission efficiency from the power transmission amount and a power reception amount and stops transmitting power if it is determined that a relationship between the power transmission amount and the power transmission efficiency lies out of an operable region, and the power reception device having a power reception amount detecting unit that receives power from the power transmission device and detects the power reception amount, a power reception device communication unit that communicates with the power transmission device, and a power reception device controller that transmits the power reception amount to the power transmission device via the power reception device communication unit.
