Ordered charging control method and system for electric vehicle

The invention discloses an orderly charging control method and system for an electric vehicle. And respectively carrying out power loss modeling on the PFC circuit and the DC/DC conversion circuit of the DC charging pile. According to the loss model of the PFC circuit, a Pareto optimization method is adopted to solve the minimum loss, so that the first optimal charging efficiency of the PFC circuit under a certain input power is obtained. And aiming at the loss model of the DC/DC conversion circuit, solving the minimum loss by adopting a Pareto optimization method so as to obtain the second optimal charging efficiency of the dual-active bridge DC/DC conversion circuit under a certain input power. And solving the optimal charging efficiency of the charging pile according to the first optimal charging efficiency and the second optimal charging efficiency. And based on the optimal charging efficiency of the charging pile, a pre-constructed target optimization function is solved through a particle swarm optimizat
