Zusammenfassung:The invention relates to a long-path charging planning method based on hierarchical space aggregation search, and the method comprises the steps: building a multi-layer virtual space, enabling each layer of virtual space to be composed of a plurality of mutually connected regular hexagons, and initializing the position of a charging station in the virtual space; acquiring the ratio k of the actual power-off quantity per kilometer to the theoretical power-off quantity per kilometer; according to the total electric quantity of the current vehicle and the ratio k, the farthest position point where the current vehicle can run is calculated; judging whether the farthest position point reaches the end point or not, and if yes, prompting the user to reach the end point without charging; if not, layer-by-layer space searching is carried out at the farthest position point of the virtual space according to the layer numbers from small to large, charging station information meeting the condition is added into the chargi
