Beschreibung
Zusammenfassung:	An apparatus to determine offset voltage to adjust a fuse current determination including a fuse load circuit structured to determine that no current is demanded for a fuse load, and to further determine that contactors associated with the fuse are open, an offset voltage determination circuit structured to determine an offset voltage corresponding to at least one component in a fuse circuit associated with the fuse, in response to the determining that no current is demanded for the fuse load, and an offset data management circuit structured to store the offset voltage, and to communicate a current calculation offset voltage for use by a controller to determine current flow through the fuse.
