Abstract: A power system for electric or partially-electric machines or vehicles is described herein. The disclosure includes a fully or partially-electric machine including a machine body and a power system. The machine body includes an engine cavity, and the power system is positioned within the engine cavity. The power system includes a power distribution unit (PDU), one or more batteries, a secondary power source, and one or more motors including a motor. The motor is configured to be operably connected to one or more components of the machine. The PDU is electrically connected to each of the one or more batteries, the secondary power source, and the first motor. The PDU is configured to receive power from one or more of the secondary power source or the one or more batteries and provide power to one or more of the motor or the one or more batteries.

Abstract: Disclosed is a method of testing and assembling a power system of an electric or partial electric machine, the method including: assembling one or more sub-assemblies of the power system; testing one or more of the one or more sub-assemblies of the power system independently; adjusting one or more of the one or more sub-assemblies based on the testing; assembling each sub-assembly in a pre-determined location of the electric or partial electric machine; and testing the assembled power system of the electric or partial electric machine.
