Navigation server, non-transitory storage medium, and navigation system

A non-transitory storage medium storing instructions that are executable by a processor and that cause the processor to perform functions comprising:

• deriving one of a first route, a second route and a third route as a route from a place of departure to a destination of a vehicle in accordance with a remaining level of a travel battery of the vehicle, the first route including a first road provided with a first non- contact electric power feeder, the second route including a second road provided with a second non-contact electric power feeder that is different in electric power feed capability from the first non-contact electric power feeder, the third route including a third road provided with a non-contact electric power feeder that is not in operation, the first non- contact electric power feeder having higher electric power feed capability than the second non-contact electric power feeder;
• deriving the first route when the remaining level of the travel battery of the vehicle is a first remaining battery level;
• deriving the second route when the remaining level of the travel battery of the vehicle is a second remaining battery level that is larger than the first remaining battery level;
• deriving the third route when the remaining level of the travel battery of the vehicle is a third remaining battery level that is larger than the second remaining battery level;
• and
• outputting one of the derived first route, second route and third route as a recommended route to a terminal associated with the vehicle.

A navigation system, comprising:

• a terminal associated with a vehicle, the terminal including a first processor;
• and
• navigation server having a second processor, the second processor being configured to
• derive one of a first route, a second route and a third route as a route from a place of departure to a destination of the vehicle in accordance with a remaining level of a travel battery of the vehicle, the first route including a first road provided with a first non-contact electric power feeder, the second route including a second road provided with a second non- contact electric power feeder that is different in electric power feed capability from the first non-contact electric power feeder, the third route including a third road provided with a non- contact electric power feeder that is not in operation, the first non-contact electric power feeder having higher electric power feed capability than the second non-contact electric power feeder,
• derive the first route when the remaining level of the travel battery of the vehicle is a first remaining battery level,
• derive the second route when the remaining level of the travel battery of the vehicle is a second remaining battery level that is larger than the first remaining battery level,
• derive the third route when the remaining level of the travel battery of the vehicle is a third remaining battery level that is larger than the second remaining battery level, and
• output one of the derived first route, second route and third route as a recommended route to the terminal associated with the vehicle.
