  • Publication number: 20210159524
    Abstract: An apparatus for sensing voltage information of a fuel cell includes: a sensing unit configured to sense voltages of each cell and all cells included in a fuel cell; a controller configured to control the sensing unit to sense the voltages of each cell and all the cells of the fuel cell according to a command of an upper controller, or to transmit information of the sensed voltages of each cell and all the cells to the upper controller; and the upper controller configured to detect an error cell by calculating output power of the fuel cell based on the information of the voltages received from the controller, to substantially prevent damage to a surrounding cell by stopping an operation of the error cell, and to control the output power in real time in correspondence with a state of the fuel cell.

  • Patent number: 11002797
    Abstract: The fault diagnosis circuit includes a first line including a first resistor, having one end connected to the positive (+) terminal of a battery, and having the other end connected to a first input unit of an analog to digital converter (ADC); a second line including a second resistor, having one end connected to the positive (+) terminal of the battery, and having the other end connected to a first input unit of a comparator; and a third line including a third resistor, having one end connected to the negative (?) terminal of the battery, having a first other end connected to a second input unit of the ADC, and having a second other end connected to a second input unit of the comparator. A fault in a battery management system can be efficiently diagnosed using a smaller number of elements.

  • Publication number: 20210135258
    Abstract: An apparatus for measuring average power of a fuel cell may include: a voltage measurement unit configured to sequentially measure forward voltages of unit cells including a fuel cell stack from a bottom cell to a top cell, and sequentially measure reverse voltages of the unit cells from the top cell to the bottom cell; a current measurement unit configured to measure a current of an output terminal of the fuel cell stack; and a control unit configured to control the voltage measurement unit to measure the reverse voltages based on a current measurement time point, after the voltage measurement unit measures the forward voltages, and calculate average power using the forward voltages, the reverse voltages and the measured current.

  • Publication number: 20200092135
    Abstract: An IC communication device according to an embodiment of the present invention includes: a plurality of sensing ICs including a first sensing IC to an N-th sensing IC arranged to be adjacent (N is an integer equal to or greater than 2); and a controller connected to the first sensing IC, wherein when the controller in a sleep mode receives a wakeup signal and transmits the wakeup signal to the first sensing IC, the wakeup signal is transmitted in two directions to two sensing ICs, from the first sensing IC to the N-th sensing IC, arranged to be adjacent.
