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.

Abstract: A temperature sensor (Tp, Tm) detects a temperature at a contact between a live part of connector (11) for a first circuit device (10) and a live part of a connector (21) a for second circuit device (20). A controller (24) determines the occurrence of a contact failure between the live parts if a difference between an amount of change in temperature detected by the temperature sensor (Tp, Tm) per predetermined time and an amount of change in ambient temperature per predetermined time is greater than a set value.
