  • Patent number: 8564454
    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).
