Publication number: 20230280295Abstract: Described methods and systems are used for in-situ impedance spectroscopy analysis of battery cells in multi-cell battery packs. Specifically, the cell impedances are determined while the pack continues to operate, such as being charged or discharged. For example, the pack voltage/power output remains unchanged while this analysis is initiated, performed, and ended. Cell impedance is determined based on the cell's response to the signal applied to the cell. For example, a current through the cell is charged while monitoring cells' voltage response. Although the power output of the changes during this testing, but the operation of the pack is not impacted due to the power compensation provided by one or more other cells in the pack thereby ensuring uninterrupted operation of the pack. This in situ testing is provided by the unique architecture of the pack, comprising multiple nodes and individual node controllers.Type: ApplicationFiled: May 12, 2023Publication date: September 7, 2023Applicant: Element Energy, Inc.Inventors: Rainer Johannes Fasching, Georgy Zerkalov, Arnaud Devie, Seth Marshall Kahn, Anthony John Stratakos, Corrado Cammi, Anderson Rennie John, Yoosok Saw

Publication number: 20230280412Abstract: Described methods and systems provide in-situ leakage current testing of battery cells in battery packs even while these packs operate. Specifically, an external electrical current is discontinued through a tested battery cell using a node controller, to which the tested battery cell is independently connected. Changes in the open circuit voltage (OCV) are then detected by the node controller for a set period time. Any voltage change, associated with taking the tested cell offline, is compensated by one or more other cells in the battery pack. The overall pack current and voltage remains substantially unchanged (based on the application demands), while the in-situ leakage current testing is initiated, performed, and/or completed. The OCV changes are then used to determine the leakage current of the tested cell and, in some examples, to determine the state of health of this cell and/or adjust the operating parameters of this cell.Type: ApplicationFiled: May 12, 2023Publication date: September 7, 2023Applicant: Element Energy, Inc.Inventors: Rainer Johannes Fasching, Georgy Zerkalov, Arnaud Devie, Seth Marshall Kahn, Anthony John Stratakos, Corrado Cammi, Anderson Rennie John, Yoosok Saw

Publication number: 20230184844Abstract: Described herein are methods and systems for detecting variation in minor total-impedance contributors in sets of electrochemical cells. For example, a method comprises maintaining a substantially constant current through the set of electrochemical cells and obtaining multiple voltage readings of the cells while the substantially constant current is maintained. The method then proceeds with determining multiple differential capacity values from the multiple voltage readings, characterizing one or more peaks in the multiple differential capacity values, and determining the variation in the minor total-impedance contributor based on one or more peaks. More specifically, partial capacitance values can be assigned to different impedance channels based on these peaks or, more specifically, based on the separation of adjacent peaks.Type: ApplicationFiled: December 15, 2022Publication date: June 15, 2023Applicant: Element Energy, Inc.Inventors: Arnaud Devie, Georgy Zerkalov, Rainer Johannes Fasching, Nathan Brinkerhoff
