OG exemplary drawing
 
1. A method for assisting in management of electric energy of a vehicle (10) of electric or hybrid type having batteries, including the steps of:
providing a graph (1) including a plurality of nodes (N0-N9) belonging to one or more branches (1a, 1b) of the graph (1), wherein each branch (1a, 1b) is associated with a respective road route that can be travelled by the vehicle (10) between a respective starting charging station (N0) 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) acquiring current geographical coordinates of geo-positioning of the vehicle (10);
(ii) identifying, on the graph (1), a node geographically closer to said current geographical coordinates;
iii) identifying, on the basis of said node closest to the current geographical coordinates, a traveled branch of the graph (1) upon which the vehicle (10) is travelling;
(iv) acquiring the energy consumption information associated with the traveled branch upon which the vehicle (10) is travelling;
v) checking whether a current electrical charge of the vehicle batteries (10) of the vehicle allows the vehicle (10) to reach the respective arrival charging station (N6, N9) of the traveled branch; and
vi) generating a feedback signal as a function of said verification;
wherein the step (vi) of generating the feedback signal as a function of said verification includes at least one step among:
generating an acoustic signal,
generating a visual signal,
controlling an energy supplied by the batteries of the vehicle (10),
controlling an energy absorbed by an electric motor of the vehicle (10),
controlling an energy absorbed by auxiliary loads of the vehicle (10), and
generating an estimate of the expected consumption until the next recharge.
