Patent ID: 10239413

Abstract:
The invention relates to a method for the contactless charging or discharging of a battery-operated object (4) via a magnetically coupled coil pair, comprising a primary coil (6) of a charging/discharging station (2) and a secondary coil (8) of the object (4), wherein: in a first step, the object (4) is transferred into a reference position in relation to the charging/discharging station (2); in a second step, a reference parameter is determined in the reference position; in a third step, a lateral desired offset of the object (4) to the charging/discharging station (2) is determined, based on the reference parameter; and in a fourth step, based on the lateral desired offset, the object (4) is transferred into a charging/discharging position in relation to the charging/discharging station (2) in which position the contactless charging or discharging is carried out. The invention also relates to a computer program, a system (100), a charging/discharging station (2) and an object (4), which are designed to carry out the method.
