1. A power distribution system comprising:
OR-ing controllers configured to regulate transmission of power from a main power path and a backup power path including a low-voltage battery;
terminals through which power from the main power path or the backup power path is transmitted to respective components corresponding to sub-buses, each of the sub-buses comprising a relay connected in series with an electronically programmable fuse (eFuse); and
a microcontroller configured to:
acquire data in each of the sub-buses and control operations associated with each of the sub-buses based on the acquired data;
detect whether the eFuse is shut down; and
in response to detecting the eFuse is shut down, attempt to turn on the eFuse.
