Abstract
Disclosed is an apparatus and method for positioning an electric powered vehicle (34) relative to an electric recharging unit (36) utilizing an optical docking system (10). A first laser emitting diode (12) generates a first visible beam (18) and a second laser emitting diode (14) generates a second visible beam (20). The first visible beam (18) and the second visible beam (20) intersect at an intersection point (22) remote from the electric powered vehicle (34). This intersection point (22) is aligned with the electric recharging unit (36) thereby positioning the electric powered vehicle (34) at a predetermined distance and a predetermined position relative to the electric recharging unit (36).
