Abstract

A low voltage system of a vehicle having a battery, one of a generator and an accessory power module (APM), one or more low voltage load, and a smart energy center. The smart energy center having a first electronic fuse configured to selectively connect the smart energy center to the battery, a second electronic fuse configured to selectively connect the smart energy center to the one of the generator and the APM, and a third electronic fuse configured to selectively connect the smart energy center to the one or more low voltage load. The smart energy center further comprising a plurality of sensors and a controller configured to selectively activate and deactivate the first electronic fuse, the second electronic fuse, and the third electronic fuse based at least in part on data received from the plurality of sensors.
