In one illustrative embodiment, a wind-driven charging system includes a wind-driven rotation device coupled to a rotatable shaft, and a plurality of electric generators disposed at different longitudinal locations along the rotatable shaft and each of the plurality of electric generators are rotationally driven simultaneously by the rotatable shaft. By having the electric generators disposed at different longitudinal locations, more electric generators may be simultaneously driven by a common shaft. In some instances, a controller may be configured to enable more of the electric generators to provide electrical current to recharge a battery when the speed of rotation of the rotatable shaft increases, and may disable more of the plurality of electric generators to not provide electrical current when the speed of rotation of the rotatable shaft decreases.
