A navigation system for an electric vehicle includes a telematics center, a display terminal, and a charging station. In response to a request from the display terminal, the telematics center sends a route search result, which is created based on information on an electric vehicle and the charging station and which includes base point information whose remaining battery capacity is to be confirmed, to the display terminal. The display terminal displays route guidance information, the current position, and a result of comparison between the current remaining battery capacity and the base point information to the user who is driving the electric vehicle. |

1. A navigation system for an electric vehicle, said navigation system comprising a display terminal that sends and receives information to and from an electric vehicle over a network; and a server that sends and receives information to and from said display terminal over the network, wherein
said display terminal performs processing for sending a search request for a route, via which said electric vehicle moves from a starting point to a destination, to the server, the search request including position coordinates of the starting point, position coordinates of the destination, a remaining battery capacity, a battery capacity, and a start time; processing for displaying route guidance information on an output device, the route guidance information sent from said server, the route guidance information created based on a route search result that includes one or more pieces of base point information; and processing for displaying, on said output device, a result of comparison between an estimated remaining battery capacity at a battery state confirmation point, which is included in one of the pieces of the base point information, with a confirmation-point remaining battery capacity of said electric vehicle at the confirmation point and said server performs processing for searching for a route, via which said electric vehicle moves from the starting point to the destination without battery exhaustion, in response to the route search request from said display terminal; processing for deriving one or more pieces of the base point information on the searched-for route and for adding the derived base point information to the route search result, said base point information including position information on the confirmation point and a confirmation-point remaining battery capacity at the confirmation point; and processing for sending the route search result, which includes the derived base point information, to the display terminal.
