Abstract: In a remaining capacity notification device for notifying a user of a device of a remaining capacity of a secondary battery mounted in the device, a reliability level determination unit determines a reliability level of a state of charge (SOC) indicating the remaining capacity of the secondary battery that the user is to be notified of, on the basis of the slope of a SOC-open circuit voltage (OCV) curve of the secondary battery that corresponds to the SOC. A notification control unit performs control to cause the user to be notified of the remaining capacity of the secondary battery in a form of notification based on the reliability level of the SOC that has been determined.

Abstract: A travel route acquisition unit acquires a travel route of an electric vehicle. A weather information acquisition unit acquires weather information on the travel route. A route guidance information generation unit generates route guidance information based on the travel route thus acquired and the weather information thus acquired. When a low temperature area is present on the travel route, the travel route acquisition unit further acquires a different travel route, and the route guidance information generation unit generates route guidance information that recommends a travel route with few low temperature areas.
