The present invention relates to a smart grid system for supplying power to a black box for vehicles by photovoltaic power generation. The mart grid system includes: a solar cell unit which generates power using sunlight; a main system which supplies the power generated from the solar cell unit to a black box; and an embedded battery which stores the power generated by the solar cell unit from the main system. According to a change in the amount of sunlight or the parking environment of vehicles, when photovoltaic power generation is not carried out, power is firstly received from the embedded battery which stores power by photovoltaic power generation. Therefore, the discharge of a battery in a vehicle can be prevented. |
