Coil parameter optimization method for wireless charging

The invention discloses a coil parameter optimization method for wireless charging. The method comprises the following steps: firstly, sequentially solving the magnetic field intensity of each edge at each point in space from the innermost turn of coil to the outermost turn of coil of a sub-coil; the magnetic field distribution of the DD type coil in the whole space is obtained according to the superposition principle, then matrix operation is conducted on all points in the space where the whole coil is located, and then the magnetic field distribution condition of each point of the DD type coil in the space can be obtained; secondly, obtaining the magnetic field distribution condition of each point in the space according to the obtained DD type coil; based on an ant colony optimization algorithm, the sum of magnetic induction intensity superposition vectors transmitted to a receiving coil is used as an optimization basis to carry out optimization solving on parameters to be optimized, and then coil parameter
