Guide system and guide method for charging hydrogen

A method for guiding hydrogen charging, the method comprising:

• transmitting, by a first controller of a fuel cell vehicle, information for hydrogen charging to a hydrogen charger of a hydrogen charging station when the fuel cell vehicle is connected to the hydrogen charger so as to be hydrogen-chargeable and communicable;
• determining, by the hydrogen charger, whether hydrogen charging for the fuel cell vehicle is available, based on the information for the hydrogen charging transmitted by the first controller;
• recording and transmitting to a server, by the first controller, hydrogen charging information when a hydrogen tank is charged with hydrogen by the hydrogen charger;
• indexing and recording, by the server, the hydrogen charging information transmitted by the first controller for each hydrogen charging station and each charging provision pressure, and then transmitting indexed charging availability information to a second controller of another vehicle to be charged;
• and
• calculating and displaying on a display, by the second controller, a maximum chargeable amount and a required charging time for each hydrogen charging station for the hydrogen tank of the vehicle to be charged based on the indexed charging availability information transmitted by the server.
