Abstract
A system for and method of charging a battery of an electric-powered vehicle is disclosed. The system utilizes a light-transforming cell that can transform light energy to current. The cell is supported by a support material positioned either inside or outside of the vehicle such that the cell may be exposed to light energy. Current produced by the cell is provided to the battery through electrical connectors, which may have a switch. This invention allows an electric-powered vehicle to be charged whenever there is sufficient light to allow energy-converting cells to convert light energy to electric current.
