SMART POWER DISTRIBUTION UNIT

Apparatus for voltage stabilization in a vehicle includes a battery distribution module having a load module managing electrical power to one or more auxiliary loads, a first switch coupling a starter motor and an ESD to the load module only when closed, a second switch coupling an auxiliary ESD to the load module only when closed, and a controller integrated with a PC board attached to the first and second switch devices. The controller is configured to control opening and closing of the first and second switches based on at least one of a plurality of signals received by the controller. The primary ESD is electrically coupled a primary fuse terminal of the battery distribution module which electrically couples the primary ESD to a second terminal of the first switch and the starter motor. The auxiliary ESD is electrically coupled to an auxiliary fuse terminal of the battery distribution module which electrically couples a first terminal of the second switch to the auxiliary ESD.
