A method for assisting in management of electric energy of a vehicle of electric or hybrid type, including the steps of: - provide a graph including a plurality of nodes (N0-N9) belonging to one or more branches (1a, 1b) of the graph, wherein each branch (1a, 1b) is associated with a respective road route that can be travelled by the vehicle between a respective starting charging station and a respective arrival charging station (N6, N9), and wherein each branch (1a, 1b) is associated with respective information of an energy consumption that is required to travel the respective road route; - iteratively perform the following steps i)-vi): i) acquire current geographical coordinates of geo-positioning of the vehicle; (ii) identify, on the graph, a node geographically closer to said current geographical coordinates; iii) identify, on the basis of said node closest to the current geographical coordinates, which branch of the graph the vehicle is travelling; (iv) acquire the energy consumption information associated with the branch that the vehicle is travelling; v) check whether a current electrical charge of the vehicle batteries allows the vehicle to reach the respective arrival charging station (N6, N9) of the branch the vehicle is travelling; and vi) generate a feedback signal as a function of said verification. - provide a graph including a plurality of nodes (N0-N9) belonging to one or more branches (1a, 1b) of the graph, wherein each branch (1a, 1b) is associated with a respective road route that can be travelled by the vehicle between a respective starting charging station and a respective arrival charging station (N6, N9), and wherein each branch (1a, 1b) is associated with respective information of an energy consumption that is required to travel the respective road route; - iteratively perform the following steps i)-vi): i) acquire current geographical coordinates of geo-positioning of the vehicle; (ii) identify, on the graph, a node geographically closer to said current geographical coordinates; iii) identify, on the basis of said node closest to the current geographical coordinates, which branch of the graph the vehicle is travelling; (iv) acquire the energy consumption information associated with the branch that the vehicle is travelling; v) check whether a current electrical charge of the vehicle batteries allows the vehicle to reach the respective arrival charging station (N6, N9) of the branch the vehicle is travelling; and vi) generate a feedback signal as a function of said verification. i) acquire current geographical coordinates of geo-positioning of the vehicle; (ii) identify, on the graph, a node geographically closer to said current geographical coordinates; iii) identify, on the basis of said node closest to the current geographical coordinates, which branch of the graph the vehicle is travelling; (iv) acquire the energy consumption information associated with the branch that the vehicle is travelling; v) check whether a current electrical charge of the vehicle batteries allows the vehicle to reach the respective arrival charging station (N6, N9) of the branch the vehicle is travelling; and vi) generate a feedback signal as a function of said verification.
