Embodiment

[0052] A method for selecting a charging path for an electric vehicle considering a nonlinear charging function includes the following steps:

[0053] Step 1: Construct the optimization problem model of charging vehicle route selection, and establish the problem description of charging vehicle optimal route selection.

[0054] Described step 1 comprises the following steps:

[0055] Step A1: Construct the optimization problem model of charging car route selection

[0056] For example figure 1 As shown, a given path graph G=(V,E) consists of a point set V and an edge set E, where V={s,t,v 0 ,v 1 ,v 2 ,v 3 ,v 4 ,v 5 ,v 6}, E={(s,v 0 ),(v 0 ,v 1 ),(v 1 ,v 2 ),(v 2 ,v 3 ),(v 3 ,v 4 ),(v 4 ,v 5 ),(v 5 ,v 6 ),(v 6 ,t)}, the weight on the edge represents the energy consumption cost between two points. The path P in the path graph G = (v 1 ,v 2 ,...,v k ) consists of a group of nodes in V, edge e=(v i-1 ,v i ) belongs to the edge set E.
