Abstract
A system in a vehicle includes a first fuse connected between a power source and a load. The first fuse is an electronic fuse (eFuse) to disconnect the load from the power source via the first fuse based on opening a first fuse switch. The system also includes a second fuse connected between the power source and the load via a second fuse switch. The first fuse and the second fuse are part of a cluster of fuses. A controller opens the first fuse switch and keeps the second fuse switch closed based on the vehicle entering a key-off mode in which the vehicle is turned off.
