VALVE OPENING/CLOSING DETECTION DEVICE FOR FUEL CELL SYSTEM AND METHOD THEREFOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 17952666 titled 'VALVE OPENING/CLOSING DETECTION DEVICE FOR FUEL CELL SYSTEM AND METHOD THEREFOR
Simplified Explanation
- The present disclosure is about a valve opening/closing detection device for a fuel cell system and a method for detecting the opening and closing of a valve without the need for a separate sensor. - The device detects the current supplied to the valve and determines the differential value of the current. - The opening and closing of the valve are detected based on the fluctuation range of the differential value. - The device accurately detects the opening and closing time points of the valve, improving the efficiency and performance of the fuel cell system. - The device includes a current sensor to measure the current applied to the valve and a controller to determine the differential value and detect the valve opening and closing based on the fluctuation range.
Original Abstract Submitted
The present disclosure relates to a valve opening/closing detection device for a fuel cell system and a method therefor and provides a valve opening/closing detection device for a fuel cell system, which detects a current (current waveform) supplied to a valve of the fuel cell system, determines a differential value of the current, detects opening/closing of the valve on the basis of a fluctuation range of the differential value, and thus may accurately detect an opening time point and a closing time point of the valve without a separate sensor, and a method therefor. To this end, the present disclosure may include a current sensor that measures a current applied to a valve, and a controller that determines a differential value of the current and detects opening/closing of the valve on the basis of a fluctuation range of the differential value.
