Abstract: A temperature sensor detects a temperature at a contact between a live part of connector for a first circuit device and a live part of a connector a for second circuit device. A controller 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 per predetermined time and an amount of change in ambient temperature per predetermined time is greater than a set value.

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.
