Abstract
A non-intrusive sensing system for monitoring an electrochemical device and a method of operating the non-intrusive sensing system can include multi-static ultrasonic sensors for detecting data indicative of a property of electrolytic media in an electrochemical device, an acoustic sensor for detecting and measuring a signature of electrodes associated with a health condition of the electrochemical device. A temperature sensor can be used to detect surface temperature data and correlate the surface temperature data with the signature identified and extracted by the acoustic sensor and the data indicative of the property of the electrolytic media. The data detected by the multi-static ultrasonic sensors, the signature detected by the acoustic sensor, and the surface temperature data identified can be subject to feature extraction and processing by a detection and prediction model to produce information pertaining to the safety, reliability and operating efficiency of the electrochemical device.
Core Innovation
The invention describes a non-intrusive sensing system for monitoring an electrochemical device. The system includes multi-static ultrasonic sensors for detecting data indicative of a property of electrolytic media in an electrochemical device, an acoustic sensor for detecting and measuring a signature of at least one electrode associated with a health condition of the electrochemical device, and a temperature sensor for detecting surface temperature data associated with the electrochemical data.
The system correlates the surface temperature data with the signature identified and extracted by the acoustic sensor and with the data indicative of the property of the electrolytic media detected by the multi-static ultrasonic sensors. The data detected by the multi-static ultrasonic sensors, the signature detected by the acoustic sensor, and the surface temperature data identified by the temperature sensor are subject to feature extraction and processing.
In further embodiments, the system includes a strain sensor that verifies expansion and contraction data and correlates the expansion and contraction data with ultrasonic signal signatures derived from ultrasonic sensors. The strain sensor further detects pressure within a wall of the electrochemical device, and the invention can also include a multi-species gas sensor for detecting and tracking gas evolution and potential venting tied to electrolyte decomposition.
