SYSTEM AND METHOD FOR USING SOLAR CELL
First Claim
1. A system for using a solar cell, comprising:
- a solar cell module configured to convert sunlight into electric energy;
an engine operating circuit configured to convert mechanical energy generated by an engine operation of a vehicle into electric energy and provide the electric energy;
a solar cell circuit configured to provide the electric energy generated through the solar cell module;
a battery configured to be charged by electric energy provided by the solar cell circuit or the engine operating circuit;
a load; and
a controller of a vehicle, the controller configured to control a connection of the circuits to the battery or to the load depending on a measured state of charge of the battery, driving of the vehicle, and acceleration of the vehicle.

Abstract
A system for using a solar cell includes a solar cell module configured to convert sunlight into electric energy, an engine operating circuit configured to convert mechanical energy generated by an engine operation of a vehicle into electric energy and provide the electric energy, a solar cell circuit configured to provide the electric energy generated through the solar cell module, a battery configured to be charged by electric energy provided by the solar cell circuit or the engine operating circuit, a load, and a controller of a vehicle. The controller is configured to control a connection of the circuits to the battery or to the load depending on a measured state of charge of the battery, driving of the vehicle, and acceleration of the vehicle. A method for using a solar cell is also disclosed.
