The network that provides the resources is referred to as the "cloud". Resources in the cloud can be infinitely expanded in the sense of users, can be acquired at any time, can be used as required and can be expanded at any time. By establishing a cloud computing resource pool (cloud platform for short, generally called IaaS (Infrastructure AS A SERVICE) platform), multiple types of virtual resources are deployed in the resource pool for external clients to select for use.

Step 232, selecting the target energy replenishment site from the energy replenishment sites located in the first geographical area.
In the present application, since the first geographic area is a geographic area limited by the initial navigation path and the range as a radius, it is understood that the vehicle may reach any one of the energy supplement sites in the first geographic area. Thus, the target energy replenishment site may be selected among the individual energy replenishment sites located within the first geographical area.
In one embodiment of step 232 shown in fig. 5, selecting the target energy replenishment site from among the individual energy replenishment sites located within the first geographic area may be performed in accordance with the steps shown in fig. 6.

Step 2323, displaying the energy replenishment sites in the first geographical area of the target.
Step 2324, determining the selected energy replenishment site as the target energy replenishment site in response to the selection operation for the displayed energy replenishment site.
In the application, a plurality of first geographic subareas can be determined in the first geographic areas, and first priority scores can be determined for the first geographic subareas, wherein the first priority scores can be used for representing the priority degree of the first geographic subareas, and in particular, the higher the first priority score of one first geographic subarea is, the more suitable the first geographic subarea is as an energy supplementing site selection area of a vehicle.
In the application, the first geographical sub-area with the highest first priority score can be used as a target first geographical sub-area, and the energy supplementing site in the target first geographical sub-area is displayed for the user to select.

And 2, acquiring the distribution quantity of the energy supplementing stations in each first geographical sub-area.
And step3, calculating the first priority score based on the relative distance and/or the distribution quantity.
In the present application, the first priority score may be calculated based on the relative distance, where the first priority score may be inversely related to the relative distance, that is, the smaller the relative distance between the area center of the first geographical sub-area and the initial navigation path, the higher the calculated first priority score.
