| 摘要 |
The present invention relates to a grid system for supplying power to a black box for a vehicle by means of photovoltaic power generation, the grid system comprising: a solar cell unit for generating power by using photovoltaic power generation; a main system for supplying a black box with the power generated from the solar cell unit; and an internal battery for storing the power which is from the main system and generated by a solar cell unit. The effectiveness is provided in which, if photovoltaic power generation is not performed due to a change in the amount of sunlight or the vehicle's parking state, discharging of a battery inside a vehicle is prevented by enabling the supply of power first from an internal battery that stores the power from photovoltaic power generation. |
