Abstract

See full text

Systems and methods for reallocation of electronic fuses (EFn). The method includes concurrently receiving, for a plurality (N) of EFn, respective sensor data and comparing the sensor data to respective operating ranges. An EFn that exceeds its operating range is turned off. Wherein a preprogrammed configuration of a fuse harness defines multiple (M) clusters, the method identifies, for each EFn that is within the operating range, whether the EFn is a member of a cluster of the M clusters, and other members of the cluster. The method monitors each cluster member's sensor data, with respect to preprogrammed thresholds and load current demands, to thereby categorize each EFn in each cluster as either healthy, derated, or failed. For failed EFns, a target EF in the same cluster having a reallocation potential is identified, and its fuse limits are modified in accordance with the reallocation potential.
