It's not uncommon to find off-road vehicles equipped with a winch system, though they're nearly always a bumper-mounted electric system added after production. This new patent details an integrated winch that sources its power directly from the high-voltage battery and electric drive motors already present in an EV. That patent does not specifically state as much, but the door is open to having a front and rear winch or a combination of both.

The system the patent outlines diverts torque from the front or rear axles and redirects it through a planetary gear set to drive the winch spool. The patent doesn't detail the exact location of the onboard winch, but rather, details the technology. The beauty of the patent design is that, by sourcing its power from an existing traction motor, it eliminates the need for a separate winch motor.
