Abstract

A method of operating a fuel cell system which is controlled by an electronic device includes: transmitting a bit stream including a bit string which indicates identification information of the fuel cell system and a bit string which indicates status information of the fuel cell system to the electronic device through a serial communication line; receiving a bit stream including a bit string which indicates control information of the fuel cell system from the electronic device through the serial communication line; obtaining the control information of the fuel cell system from the received bit stream; and controlling power production of a fuel cell by controlling operations of peripheral devices of the fuel cell system based on the obtained control information of the fuel cell system.

First claim

What is claimed is:

1. A method of operating a fuel cell system which is controlled by an electronic device, the method comprising:
generating a bit stream comprising a bit string which indicates identification information of the fuel cell system and a bit string which indicates status information of the fuel cell system by generating the bit string which indicates the status information by encoding the status information of the fuel cell system and then adding the bit string which indicates the status information after the bit string which indicates the identification information;
transmitting the bit stream to the electronic device through a serial communication line;
receiving a bit stream comprising a bit string which indicates control information of the fuel cell system from the electronic device through the serial communication line;
obtaining the control information of the fuel cell system from the received bit stream; and
controlling power production of a fuel cell of the fuel cell system by controlling operations of peripheral devices of the fuel cell system based on the obtained control information of the fuel cell system,
wherein the generating the bit stream comprises:
extracting a plurality of binary codes, which are mapped into a plurality of sections, from a predetermined table; and
encoding the status information of the fuel cell system by combining the extracted binary codes corresponding to status information of components of the fuel cell system based on a predetermined order,

wherein the sections correspond to the status information of a component of the fuel cell system, and
the sections, which are obtained by dividing a total range of a changeable status of the component of the fuel cell system, and the binary codes are mapped to each other in one-to-one correspondence in the predetermined table.

2. The method of claim 1 , wherein the generating the bit stream further comprises converting the status information of the components of the fuel cell system into binary values, and determining the converted binary values as the binary codes corresponding to status information.

3. The method of claim 1 , wherein the generating the bit stream comprises generating the bit stream by adding a start bit string having a predetermined pattern, which indicates the start of transmission of the identification information of the fuel cell system, before the bit string which indicates the identification information.

4. The method of claim 1 , further comprising:
transmitting a bit stream including a bit string which indicates a portion of the identification information of the fuel cell system and a bit string which indicates a portion of the status information of the fuel cell system.

5. A fuel cell system which is controlled by an electronic device, the fuel cell system comprising:
a fuel cell which produces power using a fuel;
a balance of plants which supplies the fuel to the fuel cell;
a controller which generates a bit string which indicates status information of the fuel cell system by encoding the status information, and controls a power production of the fuel cell by controlling an operation of the balance of plants based on control information of the fuel cell system; and
an interface which transmits a bit stream comprising the generated bit string to the electronic device and a bit string which indicates identification information of the fuel cell system through a serial communication line, and receives a bit stream comprising a bit string which indicates the control information of the fuel cell system from the electronic device through the serial communication line,
wherein the interface receives power from the electronic device or supplies power to the electronic device, through the serial communication line and
the interface supplies power to the electronic device by transmitting successive bits corresponding to maximum transmissible voltage values of a signal to the electronic device after the transmitted bit stream.

6. The fuel cell system of claim 5 , wherein the controller generates the bit stream, which is transmitted to the electronic device, by adding the bit string which indicates the status information of the fuel cell system after the bit string which indicates the identification information of the fuel cell system.

7. The fuel cell system of claim 5 , wherein the interface receives power from the electronic device or supplies power to the electronic device, through a power line, which is different from the serial communication line.

8. A method of controlling a fuel cell system using an electronic device, the method comprising:
receiving a bit stream including a bit string which indicates identification information of the fuel cell system and a bit string which indicates status information of the fuel cell system from the fuel cell system through a serial communication line;
obtaining the identification information of the fuel cell system and the status information of the fuel cell system from the received bit stream by decoding the bit string which indicates the status information of the fuel cell system, which is received after the bit string which indicates the identification information of the fuel cell system;
generating control information of the fuel cell system based on the obtained identification information of the fuel cell system and the obtained status information of the fuel cell system;
generating a bit stream including a bit string which indicates the control information of the fuel cell system; and
transmitting the generated bit stream to the fuel cell system through the serial communication line,
wherein the obtaining the identification information of the fuel cell system and the status information of the fuel cell system comprises extracting each of binary codes corresponding to status information of components of the fuel cell system based on a predetermined order from the bit string which indicates the status information of the fuel cell system, and decoding the bit string which indicates the status information of the fuel cell system by determining status information corresponding to each of the binary codes,
wherein the obtaining the identification information of the fuel cell system and the status information of the fuel cell system further comprises:
detecting a section mapped to each of the extracted binary codes from a table, in which a plurality of sections, which are obtained by dividing a total range of a changeable status of each of the components of the fuel cell system, and a plurality of binary codes are mapped to each other in one-to-one correspondence; and
