  • Sensing feature on fuse element for detection prior to fuse open
    Patent number: 10164300
    Abstract: A sensing circuit, a vehicular battery pack using a sensing circuit, a method of protecting a circuit with a fuse and a method of providing battery power to a vehicle. The sensing circuit includes the fuse, which is made up of a main element and a sensing element such that the sensing element defines a pre-open detection capability through at least one of a dissimilar geometric profile or a different material choice from that of the main element. The sensing circuit also includes an electrical connector between one or more battery cells and an electronic control module so that the circuit provides indicia of the fusing event.
