Publication number: 20230324461Abstract: A system and method for monitoring characteristics of an electric energy device includes generating an external short from the electric energy device. The external short occurs at a known distance from a sensor and has at least one known external resistance. The received signal representing change in electromagnetic field due to the applied external short may be analyzed to determine a signal parameter that is then analyzed in comparison to a lookup table, based on the known conditions including distance, temperature and the external resistance. The output of this analyses in comparison with expected values may be utilized to identify a characteristic of the energy device.Type: ApplicationFiled: December 13, 2022Publication date: October 12, 2023Applicant: California Institute of TechnologyInventors: Farshid ROUMI, Mahshid ROUMI
