Abstract
As part of a start-up sequence, a controller of a machine causes one or more activation components of a battery of the machine to be enabled, then causes one or more electrical components associated with the battery to be enabled, then causes one or more non-accumulator components of a hydraulic system to be enabled, then causes one or more accumulator components of the hydraulic system to charge, and then causes one or more propulsion components to be enabled. As part of a shut-down sequence, the controller causes the one or more propulsion components to be disabled, then causes the one or more accumulator components of the hydraulic system to bleed, then causes the one or more non-accumulator components of the hydraulic system to be disabled, and then causes the one or more electrical components associated with the battery to be disabled.
