Abstract: A work machine that is powered by batteries in a power unit uses a locally distributed electrical system and a locally distributed hydraulic system. A portion of power from the power unit is provided to an inverter installed in a front section of the work machine to power electrical equipment installed in the front section. Another portion of the power from the power unit is provided to an inverter installed in a rear section of the work machine to power electrical equipment installed in the rear section. Additionally, a hydraulic pump installed in the front section pressurizes hydraulic fluid in a front accumulator for use by hydraulic loads in the front section and a hydraulic pump installed in the rear section pressurizes the hydraulic fluid in a rear accumulator for use by hydraulic loads in the rear section.
