Abstract: Provided is a power generation facility used in a power transmission system that charges a storage battery mounted on a moving body with power generated by the power generation facility; and feeds power from the storage battery transported by the moving body to a power receiving facility. The power generation facility includes: a power generator; and a converter that converts alternating-current power generated by the power generator to direct-current power. The power generation facility is configured to transmit the direct-current power to an outside of the facility using a cable.

Abstract: Provided is a moving body used in a power transmission system that charges a storage battery mounted on the moving body with power generated by a power generation facility and feeds the power to a power receiving facility from the storage battery transported by the moving body. This moving body is provided with a battery control device that causes the storage battery to be charged with the supply of power based on a voltage value that does not reach a maximum voltage value of direct-current power between the power generation facility and the power receiving facility.

Abstract: a A rapid-charging device can be easily installed in various locations. The rapid-charging device for rapidly charging an electric vehicle includes: a storage battery; a first converter that converts power from a commercial power source and charges the storage battery; and a second converter that converts power from the storage battery, discharges the same to an on-vehicle storage battery of the electric vehicle, and rapidly charges the on-vehicle storage battery.

Abstract: [Problem] To efficiently transport an energy source such as electricity to any reception facility without using a power transmission cable. [Solution] An energy transport system 100 comprises: a transport ship 10 that is equipped with holding means for an energy source; a supply facility 20 that supplies the energy source to the holding means of the transport ship 10; and a reception facility 30 that receives the energy source supplied from the holding means of the transport ship 10. Examples of the energy source held in the holding means of the transport ship 10 include electricity and hydrogen.
