Abstract
Methods and apparatus are disclosed for controlling power for a work machine. An example method disclosed herein includes identifying an energy storage level of an energy storage device; identifying a transmission setting of the work machine; and determining whether to control a function of the work machine using power from the energy storage device or power from a second power source different from the energy storage device based on the energy storage level and the transmission setting.
