Information provision device and information provision method
First Claim
1. An information provision device comprising:
- an acquisition unit configured to acquire travelling information of an electric vehicle on which a secondary battery is mounted;
a charge output estimation unit configured to estimate, on the basis of the travelling information, a charge output value of a charging device which is provided in a predetermined area and charges the secondary battery of the electric vehicle, the charging device being separate from the electric vehicle and from the information provision device;
a judgment unit configured to judge, on the basis of the estimated charge output value, whether there is a risk that shortage of a charge amount of the charging device will occur in the predetermined area; and
an information provision unit configured to provide recommendation information concerning charge of the electric vehicle to the electric vehicle according to a judgment result of the judgment unit.

Abstract
In order to suppress charge amount shortage in a predetermined area, an information provision device has an acquisition means that acquires travelling information of an electric vehicle on which a secondary battery 204 is mounted; a charge output estimation means that estimates, on the basis of the travelling information, a charge output value of a charging device which is provided in a predetermined area; a judgment means that judges, on the basis of the estimated charge output value, whether there is a risk that shortage of a charge amount will occur in the predetermined area; and an information provision means that provides recommendation information concerning charge of the vehicle to the electric vehicle according to a judgment result of the judgment means.

14. An information provision method for a system including an information provision device, the method comprising:
-
a step that, by a CPU, the system acquires travelling information of an electric vehicle on which a secondary battery is mounted; a step that, by a CPU, the system estimates, on the basis of the travelling information, a charge output value of a charging device which is provided in a predetermined area and charges the secondary battery of the electric vehicle, the charging device being separate from the electric vehicle and from the information provision device; a step that, by a CPU, the system judges, on the basis of the estimated charge output value, whether there is a risk that shortage of a charge amount of the charging device will occur in the predetermined area; and a step that, by a CPU, the system provides recommendation information concerning charge of the vehicle to the electric vehicle according to a judgment result.
