Abstract
A charging device is disclosed. A housing of the charging device has a placement surface on which an object to be charged is allowed to be placed. The object to be charged includes a first coil. The charging device includes a second coil and a controller. The second coil is housed in the housing at a position corresponding to the first coil. The controller acquires a parameter indicating a distance between the first coil and the second coil. The controller generates inductive coupling between the first coil and the second coil when the distance indicated by the parameter is less than a distance threshold. The controller generates resonant coupling between the first coil and the second coil when the distance indicated by the parameter exceeds the distance threshold.
