The invention discloses a maximum efficiency tracking method of an electric automobile magnetic coupling wireless charging system. First of all, mutual inductance between an emission coil and a receiving coil is derived through an initial power supply extraction frequency, and a fitness function is converted into an only frequency-related function; and particle swarm scale in a general particle swarm algorithm is set apart, which is respectively a maximum particle swarm scale Nmax=30 and a minimum particle swarm scale Nmin=2, and the particle swarm scale is gradually decreased as the iteration frequency is increased. According to the invention, redundant particles are reduced from a particle swarm algorithm, the particle swarm scale is changed, the algorithm is concise, and the convergence speed of the algorithm is accelerated. The particle swarm algorithm enables selection of particle scale to be reliably based, the algorithm has a quite large self-learning capability and a social learning capability at a search early stage, and at a later search stage, the convergence speed is accelerated, and the algorithm search time is reduced.
