Abstract
A system for storing and recovering energy associated with a machine having ground engaging tracks is disclosed. The system includes a power source configured to supply mechanical energy for operation of the machine, and an electric generator operably coupled to the power source. The electric generator is configured to convert at least a portion of the mechanical energy into electric energy. The system further includes an electric motor operably coupled to the electric generator. The electric motor is configured to supply power to the ground engaging tracks. The system includes an energy storage device configured to store energy associated with the machine, and a controller configured to divert a portion of the energy supplied by the power source to the energy storage device while the machine travels in a first direction, and recover energy stored in the energy storage device for use while the machine travels in a second direction.
