PURPOSE: A contactless charging system including a coil position display device is provided to induce the position of a second coil with regard to a first coil to obtain high charging efficiency by displaying the position of the second coil on a portable display device. CONSTITUTION: A second coil (40) of a receiving unit (30) is installed on a first coil (20) of a transmitting unit (10). A battery (50) is electrically connected to the second coil of the receiving unit. The battery is charged with induced electromotive force which is generated between the first coil and the second coil. A coil position display device (70) displays the position of the second coil on a display device (3) of a portable unit (2). The position of the second coil is displayed on the display device for a preset period in which the portable unit is switched into a charging mode. |
