  • Modular Equipment Center Distributed Primary Power Architecture
    Publication number: 20150102661
    Abstract: A plurality of modular equipment centers (MECs) spatially distributed throughout a vehicle servicing equipment loads. Each MEC independently provides localized power and communication to service the equipment loads and each equipment load is serviced by the nearest MEC. In at least one embodiment, only primary power is distributed across section breaks of the vehicle to minimize the number of connections between section breaks, reduce overall vehicle weight, and to increase vehicle build rate.

  • Vehicle electrical power management and distribution
    Patent number: 8738268
    Abstract: Vehicles, systems, and methods are disclosed for providing and directing first power, such as vehicle generator power, and alternate sources of power. In a particular embodiment, a vehicle includes a power distribution grid that includes a plurality of power sources and a plurality of distributions buses configured to distribute power from the plurality of power sources. The plurality of power sources include an engine-driven power source is configured to provide first power where the first power has first power characteristics. The plurality of power sources also includes a plurality of engine-independent power sources including a first alternate power source configured to provide first alternate power. The first alternate power has first alternate power characteristics that are different than the first power characteristics. The plurality of engine-independent power sources also includes a second alternate power source configured to provide second alternate power.
