Patent number: 11978867Abstract: A battery monitoring system for a battery pack having battery cells including a test cell and a reference voltage. The battery monitoring system includes built-in-test circuitry associated with the test cell. The built-in-test circuitry has a monitoring control operable to permit electric current between the reference voltage and the test cell and an enabling control operable to permit electric current between the reference voltage and the test cell. The battery monitoring system also includes battery monitoring circuitry having cell monitoring voltage interfaces configured to receive cell voltages associated with the battery cells and a built-in-test interface operable upon actuation by the battery monitoring circuitry to operate the monitoring control. A method for operating circuitry associated with the battery monitoring system is also provided.Type: GrantFiled: October 3, 2022Date of Patent: May 7, 2024Assignee: Air Transport Safety Inc.Inventors: Inder J. Verma, Willard A. Blevins
