Zusammenfassung:	A system includes a vehicle including a motive electrical power path; a power distribution unit having a current protection circuit disposed in the motive electrical power path, the current protection circuit comprising a fuse; a controller, comprising: a fuse status circuit structured to determine a fuse event value; a fuse management circuit structured to provide a fuse event response based on the fuse event value; and a fuse life description circuit structured to determine a fuse life remaining value, wherein the fuse event value comprises a representation that the fuse life remaining value is below a threshold value, and wherein the fuse management circuit is further structured to provide the fuse event response further based on the fuse life remaining value.
