Electric power transport ship and method using thereof

The present invention discloses a power transport ship. Power transport ship according to the invention the power generation unit for producing power using the green energy; A power storage unit in which a plurality of battery packs including at least two secondary batteries are connected in series and / or in parallel to store power generated by the power generation unit; And a controller configured to monitor electrical characteristics of the power storage unit and output a control signal for controlling charging and discharging of the power storage unit. According to the present invention, it is possible to overcome the limitations caused by weather and local conditions that operate when power is produced using green energy. In other words, by using the characteristics of the ship that can move, it is possible to produce power in the desired area.
