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.

Abstract: In a vehicle power supply system mounted on an electric vehicle, a vehicle controller switches a discharge power limit to a motor during travel of the electric vehicle according to degradation information of a battery module to which a plurality of cells are connected, the degradation information being calculated in advance before the travel of the electric vehicle. For example, the vehicle controller switches a limit of a maximum acceleration and/or maximum speed of the electric vehicle as the switching of the discharge power limit.
