Abstract: A cooling system of a battery for an electric or hybrid vehicle includes a cooling device and a thermal interface. The cooling device generates a movement of a cooling fluid between an inlet point and an outlet point in a cooling direction. The thermal interface has a first surface at least substantially in contact with the cooling device and a second surface, referred to as the heat-exchange surface, opposite the first surface, intended to be placed in contact with or near a battery. The size of the heat-exchange surface in a secondary direction, perpendicular to the cooling direction of the cooling system, increases in the cooling direction.

Abstract: A method is for protecting an electrical architecture including a protective device provided with a protective fuse capable of melting in a deteriorated mode of operation during which a breaking current having an amperage greater than a threshold is flowing through the architecture. The method includes, in a nominal mode of operation, periodically estimating a temperature of the fuse and controlling an amperage of a useful current flowing through the fuse such that the estimated temperature remains below a melting temperature of the fuse.
