Abstract
A vehicle winch mechanism includes a drum, a motor and transmission, at least one drum and motor side support, at least one battery, and a motive trickle charge mechanism. The drum pays out and takes in a line. The motor and transmission drive the drum. The side supports couple the drum, the motor, or both to the vehicle. The battery provides power to the motor. The motive trickle charge mechanism charges the battery. In one embodiment, the motive trickle charge mechanism includes a permanent magnet, an enclosure housing the magnet, and two or more sets of conductive coils wrapped around the enclosure and electrically coupled to the battery. The enclosure houses the magnet such that the magnet freely moves and changes orientation within the enclosure. The coils of an individual set of coils are aligned along parallel planes, and the coils of separate sets are aligned along intersecting planes.
