The invention discloses an
electric vehicle charging path optimization method giving consideration to
power grid load balance and user experience. The method comprises the steps of: S1, obtaining the current residual electric quantity and the minimum residual electric quantity of a vehicle-mounted battery on an ith
electric vehicle, and the starting point and the destination of the
electric vehicle, and calculating the charging demand of the electric vehicle user according to the current residual electric quantity, the minimum residual electric quantity, the starting point and the destination; S2, if the electric vehicle user has a charging demand, calculating an electric vehicle charging path with the
shortest distance priority to obtain an electric vehicle charging path with the shortest driving distance; S3, calculating driving time from the starting point to the charging
pile of the electric vehicle, queuing time, charging time of the electric vehicle and available time of the charging
pile in the
charging station, and obtaining total time of the electric vehicle of the charging path with the
shortest distance priority; and S4, by taking the minimum total duration of electric vehicles under the charging paths with the
shortest distance priority of all electric vehicles as an objective function, constructing
power grid charging load balance and electric vehicle user experience constraints, and carrying out charging path optimization.
