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.
