Information providing method, information providing system and terminal each for electrically powered vehicle

An information providing method for an electrically powered vehicle, the information providing method providing information that is used for charging a power storage device mounted in a vehicle with electric power supplied from outside the vehicle, the information providing method comprising:

• causing a server to receive a charging request including a desired charging manner, wherein the desired charging manner indicates a prioritization of (i) a charging time reduction;
• (ii) leisure activities during charging;
• or (iii) a reduction in fee;
• causing the server to select a plurality of candidates from among a plurality of charging facilities each configured to charge the power storage device in accordance with (i) location information about the vehicle, (ii) location information about each of the plurality of charging facilities, (iii) location information about each of a plurality of surrounding facilities where a user of the vehicle can stay during charging in a corresponding charging facility of the plurality of charging facilities, and (iv) the desired charging manner;
• causing the server to provide a terminal used by the user with information showing the plurality of candidates selected;
• causing the server to predict a charging time for the power storage device using (i) information about a state of charge (SOC) of the power storage device, (ii) information about a charging capability of a charger provided in each of the plurality of charging facilities, (iii) information about a fully charged capacity of the power storage device, and (iv) the desired charging manner;
• causing the server to calculate a time difference between the charging time predicted and an expected stay time for the user staying in a surrounding facility associated with each of the plurality of candidates selected;
• causing the server to deliver an advertisement for the surrounding facility associated with each of the plurality of candidates selected when the time difference is shorter than a prescribed value;
• and
• causing the server to receive information about a candidate selected with the terminal from among the plurality of candidates by the user referring to the advertisement for the surrounding facility;
• and
• causing the server to deliver a plan to spend time in the surrounding facility associated with each of the plurality of candidates selected, the plan including:
• (i) a time required for the electrically powered vehicle to travel from its current location to the candidate selected with the terminal;
• (ii) the charging time;
• (iii) the expected stay time for the user staying in the surrounding facility;
• and (iv) a time required for the electrically powered vehicle to travel from the candidate selected with the terminal to its destination.
