Abstract: A work machine using a direct current power system that isolates reactive loads is described herein. The work machine uses a machine power distribution unit that receives direct current power from two or more battery banks of a power unit, whereby each of the battery banks deliver electrical power on a separate direct current bus. A machine power distribution unit of the work machine receives the electrical power from the battery and is used to isolate the power using bus connectors. One of the battery banks provides power to one direct current bus of the work machine and another battery bank provides power to another direct current bus of the work machine. A reactive load serviced by one of the battery banks is electrically disconnected from another reactive load serviced by the other battery bank.

Abstract: A work machine using a distributed controller network that provides for redundant data buses is described herein. The work machine uses a controller area network that provides for redundant data buses for tier 1 controllers, or controllers that are determined to have a higher degree of importance when compared to other controllers. The controller area network uses redundancy to decrease the probability of a communication failure between tier 1 controllers and tier 2 controllers. The tier 1 controllers have communication access to two data buses between other tier 1 controllers and tier 2 controllers. Thus, if a data bus used by a tier 1 controller cannot be used by the controller, the tier 1 controller can use the other, redundant data bus to maintain communication.
