ACTIVE CURRENT INJECTION THROUGH A FUSE FOR AN ELECTRIC MOBILE APPLICATION

A system includes a vehicle comprising a motive electrical power path; a power distribution unit comprising a current protection circuit disposed in the motive electrical power path, the current protection circuit comprising a fuse; a current source circuit electrically coupled to the fuse and structured to inject a current across the fuse; and a voltage determination circuit electrically coupled to the fuse and structured to determine at least one of an injected voltage value and a fuse impedance value.
