A site selection method and system for electric vehicle charging piles

Abstract

The invention discloses a site selection method and system for an electric vehicle charging pile. The method comprises the following steps: classifying potential charging event data according to regional types, and determining the charging duration of a random charging event at [t, t + 1] at the starting moment in each grid corresponding to the regional types in a space grid map by adopting a kernel density estimation method according to the potential charging event data corresponding to the regional types. and determining the number of the single-grid charging piles when the single-grid charging satisfaction rate of each grid is highest according to the random charging event; judging whether the sum of the number of the single charging piles of each grid is smaller than or equal to a preset sum of the charging piles; if yes, determining the positions of the electric vehicle charging piles according to the number of all the single-cell charging piles; and otherwise, subtracting 1 fromthe number of the single-grid charging piles of the grid with the minimum pile number gradient, so that the number of the charging piles meets the requirements, the charging pile arrangement positionwith the maximum random charging event meeting rate is obtained, and the goals of the optimal random charging event meeting rate and the optimal charging pile utilization rate are achieved.

Description

technical field [0001] The invention relates to the technical field of charging piles, in particular to a site selection method and system for electric vehicle charging piles. Background technique [0002] In order to alleviate the problems of air pollution and energy consumption caused by traditional motor vehicles, electric vehicles, as the leading direction of the future development of the automobile industry, have broad prospects for development. However, the unsuitable electric vehicle charging facilities and inconvenient charging have greatly hindered the development of electric vehicles. On the one hand, the pace of construction of charging facilities lags behind the growth of electric vehicle ownership, resulting in a demand gap; The "idle" phenomenon exists at the same time. [0003] If the long-term gap in charging demand is allowed to exist, the demand for electric vehicles will not be met, which will limit the promotion of electric vehicles. However, if a larg...

However, the unsuitable electric vehicle charging facilities and inconvenient charging have greatly hindered the development of electric vehicles

On the one hand, the pace of construction of charging facilities lags behind the growth of electric vehicle ownership, resulting in a demand gap; "Idle" phenomenon exists at the same time

[0003] If the long-term gap in charging demand is allowed to exist, the demand for electric vehicles will not be met, thereby limiting the promotion of electric vehicles

However, if a large number of charging stations are deployed blindly, the charging piles will not be fully utilized, which will lead to a large waste of public resources.
