Abstract
A hybrid winch system is disclosed, including but not limited to an electric winch; an electric generator for providing generator power to the electric winch; a battery for providing stored power to the electric winch; an anchor cable wound around a roller drum for the electric winch; an anchor attached to a distal end of the anchor cable; and a controller for applying the generator power and the stored power to the electric winch. A method for controlling the hybrid winch is also disclosed.
Claims6
A hybrid winch system, the system comprising:
- an electric winch;
- an electric generator for providing generator power to the electric winch;
- a battery for providing stored power to the electric winch;
- an anchor cable wound around a roller drum for the electric winch;
- an anchor attached to a distal end of the anchor cable;
- and
- a controller for applying the generator power and the stored power to the electric winch;
- a controller processor;
- a non-transitory computer readable medium in data communication with the controller processor;
- and
- a computer program stored in the non-transitory computer readable medium, the computer program comprising:
- instructions to determine if generator power failed;
- instructions to exit the program if the generator power has not failed;
- and
- instructions to, when the generator power has failed, measure tension on an anchor cable attached to the winch and an anchor and instructions to adjust torque of the winch pulling the anchor cable in a controlled release.

A method for controlling a hybrid winch, the method comprising:
- determining at a winch controller processor if generator power failed;
- exiting the program if the generator power has not failed;
- and
- measuring tension on an anchor cable attached to the winch and an anchor and instructions to adjust torque of the winch pulling the anchor cable in a controlled release, when the generator power has failed.
