INFORMATION PROVIDING SYSTEM, INFORMATION CENTER, IN-VEHICLE DEVICE AND INFORMATION PROVIDING METHOD
First Claim
1. An information providing system for providing a passenger with information, the information providing system comprising:
- an in-vehicle device installed in an electric vehicle, wherein the passenger is provided with the information via the in-vehicle device, the in-vehicle device including;
a notifier for notifying the passenger of a congested state of a charge station candidate,whereinthe notifying is implemented by estimating of the congested state of the charge station candidate at a time point when an own electric vehicle reaches the charge station candidate which is a charge station reachable with a state-of-charge of the own electric vehicle, andthe estimating is implemented based on;
a piece of position information and the state-of-charge of the own electric vehicle, anda piece of position information and a state-of-charge of another electric vehicle which is present around the charge station candidate.

Abstract
An information providing system (1) for providing a passenger with information includes an in-vehicle device (30) installed in an electric vehicle (EVn), wherein the passenger is provided with the information via the in-vehicle device (30). The in-vehicle device (30) includes a notifier (38) for notifying the passenger of a congested state of a charge station candidate (CS1). The notifying is implemented by estimating (42) of the congested state of the charge station candidate (CS1) at a time point when an own electric vehicle (EV1) reaches the charge station candidate (CS1) which is a charge station (CS) reachable with a state-of-charge (SOC) of the own electric vehicle (EV1), and the estimating (42) is implemented based on: position information and the state-of-charge (SOC) of the own electric vehicle (EV1), and position information and a state-of-charge (SOC) of another electric vehicle (EV2-EVn) which is present around the charge station candidate (CS1).

8. An information center so configured to interactively communicate with an electric vehicle as to provide the electric vehicle with information, the information center comprising:
-
a receiver for receiving a piece of position information and a state-of-charge of the electric vehicle which are transmitted from each of the electric vehicles capable of communicating with the receiver; an estimator for estimating a congested state of a charge station candidate at a time point when an object electric vehicle reaches the charge station candidate which is a charge station defined as a process object and reachable by the object electric vehicle as an object of providing the information, wherein the estimating is implemented based on a piece of position information and a state-of-charge of another electric vehicle which is present around the charge station candidate; and a transmitter for transmitting, to the object electric vehicle, congestion information showing the thus estimated congested state of the charge station target.

9. An in-vehicle device of an electric vehicle capable of interactively communicating with an information center for providing information, the in-vehicle device comprising:
-
a transmitter for transmitting, to the information center, a piece of position information of an own electric vehicle and a state-of-charge of the own electric vehicle; a receiver for receiving, from the information center, congestion information showing a congested state of a charge station candidate at a time point when the own electric vehicle reaches the charge station candidate which is a charge station reachable with the state-of-charge of the own electric vehicle, wherein the congested state is estimated based on a piece of position information and a state-of-charge of another electric vehicle which is present around the charge station candidate; and a notifier for notifying a passenger of the congested state of the charge station candidate based on the congestion information received by the receiver.

10. A method of providing information to a passenger of an electric vehicle, the method comprising:
-
estimating a congested state of a charge station candidate at a time point when an own electric vehicle reaches the charge station candidate which is a charge station reachable with a state-of-charge of the own electric vehicle, wherein the estimating is implemented based on; a piece of position information and the state-of-charge of the own electric vehicle, and a piece of position information and a state-of-charge of another electric vehicle which is present around the charge station candidate; and notifying, thereby, the passenger of a result of the estimating.
