Abstract
A machine includes a power system. The power system may include a prime mover drivingly connected to an electric generator. The power system may also include a power line operably connected to the electric generator. Additionally, the power system may include a first electrical energy storage device operable to exchange electricity with the power line. The power system may also include a second electrical energy storage device. The power system may further include power-system controls. The power-system controls may include a first power regulator. The power-system controls may also include at least one information processor configured to receive information related to at least one operating parameter of the power system and control the first power regulator based on the received information, including selectively controlling the first power regulator to receive electricity from the second electrical energy storage device and supply the electricity to the first electrical energy storage device.
