The invention relates to an electric automobile charging station and method based on a renewable energy source. The electric automobile charging station is provided with a plurality of parking places which are provided with charging piles. The electric automobile charging station is further provided with a master controller, communication equipment and an emergency power supply. A shading shed is arranged above the electric automobile charging station. A solar cell panel is laid at the top end of the shading shed. By adoption of the scheme, the renewable energy source can be the light energy or the wind energy capable of being seen and obtained everywhere or the power energy obtained through combustion of a hydrogen energy source generated through water electrolysis, and therefore energy circulation renewable utilization can be more facilitated, environmental friendliness and energy saving are achieved, and the electric automobile charging station can be switched to mains supply for power supply when the renewable energy source is insufficient; and the nearest mobile charging vehicle is emergently invoked through a cloud server for support when outage occurs to ensure that the electric automobile charging station can constantly conduct charging, the situation that use of a user is affected due to outage is avoided, and the electric automobile charging station is simple in structure and convenient to apply and has a wider application range.
