Abstract

See full text

An energy storage device for storing energy generated from operation of a work vehicle includes a ballast providing ballast weight to the work vehicle, a stator of an electric machine mounted on the work vehicle, a rotor of the electric machine fixed for rotation with the ballast, spaced from the stator by a gap, and configured for rotation relative to the stator such that the electric machine is configured to generate electrical current from rotation of the rotor and the ballast relative to the stator and to rotate the rotor and the ballast from electrical current received by the electric machine, and a gap modulator coupled to at least one of the stator and the rotor and configured to selectively adjust the gap between the rotor and the stator based on an operation of the electric machine.
