Charging Facility Notification Method and Information Presentation Device
First Claim
1. A method of guidance to a charging facility for guiding a user of an electric vehicle to the charging facility, comprising:
- searching for charging facilities existing within a range of a predetermined distance from a current position of the electric vehicle;
when a first charging facility and another charging facility having lower output power than that of the first charging facility are searched, calculating an estimated value of a remaining charged capacity of the electric vehicle if traveling to each of the searched charging facilities, the other charging facility being in a predetermined positional relationship with the first charging facility;
calculating an estimated value of a charging time if charging the electric vehicle from the estimated value of the remaining charged capacity to a predetermined charged capacity at each of the searched charging facilities; and
when a difference between the estimated value of the charging time at the first charging facility and the estimated value of the charging time at the other charging facility is a predetermined value or less, presenting the other charging facility as a recommended charging facility to the user of the electric vehicle.

Abstract
A method for guiding a user of an electric vehicle to a charging facility includes: searching for charging facilities existing within a predetermined distance from the current position of the electric vehicle; when a high-output charging facility and a low-output charging facility in a predetermined positional relationship with the high-output charging facility are searched, calculating the estimated value of a remaining charged capacity of a battery of the electric vehicle; calculating the estimated value of a charging time if charging the battery of the electric vehicle from the estimated value of the remaining charged capacity of the battery to a predetermined charged capacity at each of the searched charging facilities; and when the difference between the estimated value of the charging times at the high-output charging facility and the low-output charging facility is a predetermined value or less, presenting the low-output charging facility to the user of the electric vehicle.

12. An information presentation apparatus comprising:
-
a presentation device; and a control device configured to control the presentation device to present guidance information for guiding a user of an electric vehicle to a charging facility, the control device being further configured to; search for charging facilities existing within a range of a predetermined distance from a current position of the electric vehicle; when a first charging facility and another charging facility having lower output power than that of the first charging facility are searched, calculate an estimated value of a remaining charged capacity of the electric vehicle if traveling to each of the searched charging facilities, the other charging facility being in a predetermined positional relationship with the first charging facility; calculate an estimated value of a charging time if charging a secondary battery of the electric vehicle from the estimated value of the remaining charged capacity to a predetermined charged capacity at each of the searched charging facilities; and when a difference between the estimated value of the charging time at the first charging facility and the estimated value of the charging time at the other charging facility is a predetermined value or less, control the presentation device to present the guidance information for guidance to the other charging facility as a recommended charging facility.
