Abstract
A battery charging pad includes a moving mechanism that moves the transmitting coil, and a position detection controller that detects the position of a device housing a battery and controls the moving mechanism to move the transmitting coil in close proximity to a receiving coil. Pulse signals are supplied to a plurality of position detection coils from a pulse generator, and the echo signals are a result of coil excitation by the pulse signals. The battery charging pad position detection controller detects the position of the receiving coil and moves the transmitting coil in close proximity to the receiving coil, and the position detection controller detects the position of the transmitting coil and moves the transmitting coil to the reference position, or it moves the transmitting coil in close proximity to the receiving coil.
