Abstract
This mobile terminal charging device has a support plate in which the front surface-side part is where a mobile terminal is installed, a charging coil disposed facing the support plate on the rear surface-side of the support plate, a plurality of detection coils concentrically disposed in the charging coil on a surface opposite the support plate, and a control unit connected to the detecting coils. When a charging operation is carried out, the control unit compares the difference between a voltage value detected using a first detecting coil among the plurality of detecting coils, and a voltage value detected using two detecting coils from a group comprising the first detecting coil and at least one detecting coil disposed outward of the first detecting coil. In addition, the control unit executes a safety operation in accordance with the results of the comparison.
