The invention discloses a charging positioning method which comprises the following steps: charging request information sent by an automatic charging moving platform is obtained; supersonic wave signal detection is conducted according to the charging request information; supersonic wave signals emitted by the automatic charging moving platform; a moving path is calculated according to the supersonic wave signals; radio signals are generated according to the moving path and are sent to the automatic charging moving platform; after the automatic charging moving platform obtains the radio signals, the radio signals are deciphered and therefore the moving path is obtained; the automatic charging moving platform moves to a charging position according to the moving path and matches with an intelligent charging device; after the automatic charging moving platform matches with the intelligent charging device, storage batteries of the automatic charging moving platform are charged. An intelligent household electronic device is mounted on the automatic charging moving platform. The method can be used for automatically charging the automatic charging moving platform, and therefore the intelligent household electronic device can be automatically charged.
