System and method for electrical energy switching and control in a vehicle

Abstract

This invention discloses a device in a vehicle electrical system which determines the vehicle's operating conditions and facilitates the transfer of electrical energy between systems of electrical energy sources and their associated electrical loads based on the vehicle operating conditions. The device further determines the operating conditions of the systems of electrical energy sources and their associated electrical loads and facilitates the transfer of electrical energy between them in accordance with said operating conditions.

1 . A system for controlling electrical energy sources and loads in a vehicle, comprising:
 (a) one or more primary batteries;   (b) one or more primary loads;   (c) a starter motor;   (d) one or more auxiliary batteries;   (e) one or more auxiliary loads;   (f) an alternator; and   (g) a control device connected to and in communication with at least one of the one or more primary batteries, one or more primary loads, starter motor, one or more auxiliary batteries, one or more auxiliary loads, and alternator;   wherein the control device isolates at least one of the one or more primary batteries, one or more primary loads, starter motor, one or more auxiliary batteries, one or more auxiliary loads, and alternator when the vehicle is about to start.
