Abstract:
1. A non-contact charging device comprising: a power receiving device having at least a power receiving coil which receives electric power from a power transmitting coil in a non-contact manner by magnetic coupling; a battery which is charged by the electric power; a state-of-charge detection unit for detecting the state of charge of the battery; a permissible charging range setting unit for setting a permissible charging range indicating the range of the position of the power transmitting coil relative to the position of the power receiving coil, in which the charging of the battery is permitted, according to the state of charge detected by the state-of-charge detection unit; and a charge control unit for controlling charging power for the battery according to the state of charge detected by the state-of-charge detection unit, wherein the permissible charging range setting unit sets the permissible charging range wider as the state of charge is higher.
