    摘要: The present invention discloses a method for in-situ detection of the state of charge (SOC) of pouch-type lithium-ion batteries using ultrasonic guided waves. The invention involves attaching two circular piezoelectric patches symmetrically at a fixed distance from each other on the surface of the lithium-ion battery using a coupling agent. A function generator is controlled to produce a Hanning-window-modulated five-cycle sine signal to excite the circular piezoelectric patch located on the left side of the battery, generating ultrasonic guided waves within the battery. These waves are then received by the circular piezoelectric patch located on the right side of the battery. The received guided wave signal is processed to extract the time-domain characteristic parameters of the wave (transit time). Based on the correspondence between the guided wave characteristic parameters (transit time) and the state of charge, the method enables the detection of the SOC of the pouch-type lithium-ion battery. The invention employs a pair of circular piezoelectric patches in a one-actuation, one-reception manner for the detection of lithium-ion batteries, achieving in-situ detection of the SOC of pouch-type lithium-ion batteries without the need to record external parameters such as current and voltage.

    摘要: An automatic analyzer is provided that is capable of quickly responding when an abnormal process occurs, accurately grasping an abnormal state, and reducing frequencies of early abnormality diagnosis and component adjustment or replacement of the automatic analyzer. The automatic analyzer compares data output information with reference data output information, applies a data alarm to an item of the data output information determined to be in an abnormal state, compares system output information with reference system output information, applies a data alarm to an item of a data output information determined to be in an abnormal state, and executes a predictive diagnosis of a failure state of the automatic analyzer based on a temporal change of the data output information obtained by the analyzer using an internal standard substance as a sample and a temporal change of the system output information.
