<p><P>PROBLEM TO BE SOLVED: To provide a method for efficiently getting energy using a solar cell in an electric vehicle and an automatically foldable sun-tracking solar cell. <P>SOLUTION: The solar cell includes: a driving means for moving solar-cell panels between a state in which they are arranged in parallel on an arrangement surface and a state in which they are vertically arranged; and a sun-tracking solar-cell driving device capable of tracking the sun in all directions according to the position of the sun. Alternatively, the solar cell includes: a turntable; a solar-cell driving means for rotating the turntable; a driving means provided on the turntable; the solar-cell panels that are opened/closed with one side as a supporting point by the driving means. As mastersite of the batteries, a sun-position detection means, a means for controlling the position of the solar cell, the solar-cell driving means, and a solar-cell-home-position control means are included. Moreover, when the cell is used for a vehicle, etc., it includes the solar-cell-home-position control means for controlling the solar cell to be in the home position in starting and travelling. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
