Supply station and method capable of charging electricity and filling with hydrogen gas simultaneously or separately

A supply station capable of charging electricity and filling with hydrogen gas simultaneously or separately, the supply station comprising:

• a power supply unit for supplying electric power, a storage battery system, an electricity-hydrogen conversion device capable of converting electric power into hydrogen gas, a hydrogen gas storage system, a hydrogen-electricity conversion device capable of converting hydrogen gas into electric power, a charger, and a hydrogen dispenser, wherein the power supply unit is a power grid that supplies electric power to the storage battery system and to the charger;
• the storage battery system is configured to store the electric power supplied respectively by the power supply unit and the hydrogen-electricity conversion device;
• the electricity-hydrogen conversion device is configured to convert the electric power supplied by the power supply unit into hydrogen gas;
• the hydrogen gas storage system is configured to store the hydrogen gas generated by the electricity-hydrogen conversion device;
• the hydrogen-electricity conversion device is configured to convert the hydrogen gas provided by the hydrogen gas storage system into electric power;
• the charger is configured to:
• charge an electric vehicle with the electric power supplied by the storage battery system and the power supply unit, and
• the hydrogen dispenser is configured to fill hydrogen gas supplied by the hydrogen gas storage system into a hydrogen-powered vehicle;
• and
• wherein the storage battery system is charged with electric power supplied by the power supply unit when it is not necessary to charge the electric vehicle with electric power supplied by the power supply unit.
