The present disclosure discloses an electric-quantity-based path
planning method for an
electric vehicle compatible with an
energy storage charging
pile. The method includes the following steps: 1) charging piles in a whole network submitting state information of the piles to a dispatching
system platform, and before departure, an
electric vehicle applying for a reservation from the dispatching
system platform; 2) finding a shortest path from a departure place to a destination; 3) the dispatching
system platform judging whether the reserved allocated electric quantity of the
electric vehicle at one or more charging piles along the path meets an endurance requirement for driving to the destination; 4) if so, generating a whole-journey reservation scheme; and 5) if not, excluding the shortest path, and finding the shortest path from the remaining paths, and performing cyclic execution from Step 3) until all paths are traversed. By means of the method of the present disclosure, whole-journey electric-quantity-based path planning for an electric vehicle can be realized, the fused use of an
energy storage charging
pile and a power-grid direct-supply charging
pile is realized using
arrival time matching, and charging scheduling is also performed on the vehicle through the dispatching system platform, such that the electric quantity of the charging pile resources, especially an
energy storage pile, in a whole network is fully utilized.
