Abstract
A multi-coil placement method of a wireless charging system is disclosed. The method may include obtaining a width parameter of an effective charging area a and a width parameter of a power transmitter coil b, calculating a ratio of the width parameters a/b, determining a shape, size and number of layers of mesh cells based on the ratio of a/b, determining a layout of the mesh cells, covering a required charging area using the mesh cells based on the determined shape, size, number of layers, and layout, and replacing the mesh cells with the power transmitter coils.
