US Patent 9221409 Vehicle power distribution system

A power distribution module for use in a vehicle's power control system is provided, the use of which helps to minimize parasitic battery losses while providing additional control over the vehicle's electrical components and subsystems. The power distribution module includes a plurality of control circuits, each of which is under the control of its own circuit switch, and each of which is coupled to one or more electronic control modules. The power distribution module also includes a processor that is configured to close each of the circuit switches, thereby providing power to the corresponding control circuits, in response to current vehicle conditions and in accordance with a preset set of conditions.
