Title:
WIRELESS CHARGING POWER COIL, WIRELESS CHARGING SYSTEM AND WIRELESS CHARGING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2018/076213
Kind Code:
A1
Abstract:
A wireless charging power coil, a wireless charging system and a wireless charging control method. The wireless charging power coil comprises a first coil (1), a second coil (2) and a switching apparatus, wherein
the first coil (1) is connected to the second coil (2);
when a current rotation direction in the first coil (1) is the same as a current rotation direction in the second coil (2), it is in a polar charging mode;
when the current rotation direction in the first coil (1) and the current rotation direction in the second coil (2) are opposite, it is in a non-polar charging mode; and
the switching device is used for switching the wireless charging power coil to operate in the polar charging mode or in the non-polar charging mode, so that the costs are reduced, and the charging efficiency is improved.
