Abstract

The present disclosure provides a system and a method for guiding hydrogen charging, which may estimate a remaining hydrogen chargeable amount (remaining hydrogen storage amount), a charging time, and the like of a hydrogen charging station, and provide the estimated information to another vehicle to be charged through an Internet network when a driver charges hydrogen in a hydrogen tank of his/her fuel cell vehicle at the hydrogen charging station, such that the driver of the vehicle to be charged may recognize a maximum chargeable amount and a required charging time for a hydrogen tank of a vehicle to be charged for each hydrogen charging station, thereby allowing the fuel cell vehicles to visit the hydrogen charging station and smoothly charge hydrogen.

First claim

What is claimed is:

1. A system for guiding hydrogen charging comprising:
a first controller configured to transmit information for hydrogen charging of a fuel cell vehicle to a hydrogen charger of a hydrogen charging station, and to transmit to a sever hydrogen charging information, when a hydrogen tank is charged with hydrogen by the hydrogen charger;
the hydrogen charger configured to determine whether hydrogen charging for the fuel cell vehicle is available, based on the information for the hydrogen charging transmitted by the first controller;
the server configured to index and record the hydrogen charging information transmitted by the first controller for each hydrogen charging station and each charging pressure, and then to transmit indexed charging availability information to a second controller of another vehicle to be charged; and
the second controller configured to calculate a maximum chargeable amount and a required charging time for each hydrogen charging station for the hydrogen tank of the another vehicle to be charged based on the indexed charging availability information transmitted by the server.

2. The system of claim 1 ,
wherein the first controller transmits to the hydrogen charger of the hydrogen charging station the information for the hydrogen charging, which comprises a temperature of the hydrogen tank, and a charging command to the fuel cell vehicle, when the fuel cell vehicle is connected to the hydrogen charger of the hydrogen charging station so as to be hydrogen-chargeable and communicable.

3. The system of claim 2 ,
wherein to transmit the information for the hydrogen charging, an infrared emitter is mounted on a hydrogen charging receptacle of the fuel cell vehicle, and an infrared receiver is mounted on a charging gun of the hydrogen charger.

4. The system of claim 1 ,
wherein the first controller transmits to the server the hydrogen charging information, which comprises a charging time, a hydrogen charging pressure, an initial pressure and an ending pressure of the hydrogen tank during charging, a size of the hydrogen tank, and a position of the hydrogen charging station, when the hydrogen tank is charged with hydrogen by the hydrogen charger.

5. The system of claim 1 ,
wherein the second controller is further configured to perform a control of displaying on a display in the another vehicle the maximum chargeable amount and the required charging time for each hydrogen charging station for the hydrogen tank of the another vehicle to be charged.

6. 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 another vehicle to be charged based on the indexed charging availability information transmitted by the server.

7. The method of claim 6 ,
wherein the transmitting information for hydrogen charging to the hydrogen charger includes transmitting charging request information comprising a temperature of the hydrogen tank, a pressure of the hydrogen tank, a charging pressure, a size of the hydrogen tank, and a charging command of the fuel cell vehicle.

8. The method of claim 6 ,
wherein when the hydrogen charger determines whether the hydrogen charging for the fuel cell vehicle is available, the hydrogen charger determines that the hydrogen charging is available when a hydrogen charging pressure provided by the hydrogen charging station is smaller than or equal to a rated charging pressure for the hydrogen tank of the fuel cell vehicle, and determines that the hydrogen charging is not available when the hydrogen charging pressure provided by the hydrogen charging station is larger that the rated charging pressure for the hydrogen tank of the fuel cell vehicle.

9. The method of claim 8 ,
wherein when the hydrogen charger determines whether the hydrogen charging for the fuel cell vehicle is available, the hydrogen charger determines that the hydrogen charging is available when the hydrogen charging pressure provided by the hydrogen charging station is 350 bar and the rated charging pressure for the hydrogen tank of the fuel cell vehicle is 350 bar or 700 bar, and determines that the hydrogen charging is not available when the hydrogen charging pressure provided by the hydrogen charging station is 700 bar and the rated charging pressure for the hydrogen tank of the fuel cell vehicle is 350 bar.

10. The method of claim 6 ,
wherein when the hydrogen tank is charged with hydrogen, the first controller records a charging start time (t start ) of the hydrogen charger and an initial pressure (P start ) of the hydrogen tank, and determines whether the hydrogen tank is charged with a preset amount of hydrogen and whether the hydrogen charging for the hydrogen tank is stopped.

11. The method of claim 10 ,
wherein when the first controller determines that the hydrogen tank is charged with the present amount of hydrogen, the first controller records a full charging flag, and transmits to the server hydrogen charging information comprising a charging pressure (P charge ) of the hydrogen charger a size of the charged hydrogen tank with the preset amount of hydrogen and a position of the hydrogen charging station in addition to full charging availability information according to the full charging flag.

12. The method of claim 10 ,
wherein when the first controller determines that the hydrogen charging for the hydrogen tank is stopped, the first controller records a stop flag, and transmits to the server hydrogen charging information comprising the charging start time (t start ) and a stop time (t stop ) of the hydrogen charging, a charging termination time, the initial pressure (P start ) of the hydrogen tank and a pressure (P stop ) of the hydrogen tank at the hydrogen charging stop time point, an outside air temperature upon charging, a charging provision pressure (P charge ), a position of the hydrogen charging station, and a size of the hydrogen tank in which the charging is stopped.

13. The method of claim 6 ,
wherein when transmitting the indexed charging availability information to the second controller of the another vehicle to be charged, the server transmits charging availability information for each hydrogen charging station based on 350 bar to a vehicle mounted with a hydrogen tank of 350 bar type.

14. The method of claim 6 ,
wherein when transmitting the indexed charging availability information to the second controller of the another vehicle to be charged, the server transmits charging availability information obtained by converting 350 bar into 700 bar in addition to the charging availabilit
