Method for the contactless charging or discharging of a battery-operated object

A non-transitory computer readable medium including instructions that when run on a programmable computer cause the computer to

• control a drive to move an object (4) to a reference position with respect to the charging/discharging station (2),
• ascertain a reference parameter in the reference position,
• when the reference parameter does not meet a threshold value, ascertain a lateral desired offset of the object (4) from the reference position, a vertical desired height of the object (4) from the reference position, or both based on the reference parameter, and
• control the drive or an actuator to move the object (4) from the reference position to a charging/discharging position with respect to the charging/discharging station (2), based on the lateral desired offset, the vertical desired height, or both.

A system (100) comprising a charging/discharging station (2), a battery-operated object (4) and a control unit (10), wherein the control unit (10) is designed

• to move the object (4) to a reference position with respect to the charging/discharging station (2),
• to ascertain a reference parameter in the reference position,
• to ascertain, when the reference parameter does not meet a threshold value, a lateral desired offset from the reference position, a vertical desired height of the object from the reference position, or both based on the reference parameter,
• to move the object (4) from the reference position to a charging/discharging position with respect to the charging/discharging station (2) based on the lateral desired offset, the vertical desired height, or both, and
• to initiate contactless charging or discharging of the object (4) by means of a magnetically coupled coil pair,
• wherein the charging/discharging station (2) has a primary coil (6), the object (4) has a secondary coil (8), and the primary coil and the secondary coil form the coil pair.

A battery-operated object (4) for use in a system (100) comprising

• a charging/discharging station (2),
• the battery-operated object (4) and
• a control unit (10), wherein the control unit (10) is designed
• to move the object (4) to a reference position with respect to the charging/discharging station (2),
• to ascertain a reference parameter in the reference position,
• to, when the reference parameter does not meet a threshold value, ascertain a lateral desired offset from the reference position, a vertical desired height of the object from the reference position, or both based on the reference parameter,
• to move the object (4) from the reference position to a charging/discharging position with respect to the charging/discharging station (2) based on the lateral desired offset, the vertical desired height, or both and
• to initiate contactless charging or discharging of the object (4) by means of a magnetically coupled coil pair,
• wherein the charging/discharging station (2) has a primary coil (6), the object (4) has a secondary coil (8), and the primary coil and the secondary coil form the coil pair.
