Publication number: 20230408593Abstract: A battery management system includes a set of N battery modules coupled together in series, a set of N battery monitors, and a controller. Each battery monitor in the set of N battery monitors is coupled to a respective battery module in the set of N battery modules and measures a battery parameter of the respective battery module. The controller determines a preprogrammed delay for each battery monitor and provides the respective preprogrammed delay to each battery monitory. The controller transmits a synchronization command to the set of N battery monitors, which wait the respective preprogrammed delays in response to receiving the synchronization command before stopping updates to values of the respective battery parameters. The controller transmits a read command to the set of N battery monitors, which transmit read responses to the controller comprising values of the battery parameters.Type: ApplicationFiled: August 1, 2023Publication date: December 21, 2023Inventors: Tahar ALLAG, Kyl Wayne SCOTT

Patent number: 11340975Abstract: At least some aspects of the disclosure provide for a system. In at least some examples, the system includes a microcontroller, an energy storage element, a monitoring circuit, and a communication bridge. The monitoring circuit is coupled to the energy storage element and configured to determine whether a fault associated with the energy storage element is present, generate an indication of the fault when the fault with the energy storage element is present, and transmit the indication of the fault. The communication bridge is configured to receive the indication of the fault and assert a fault signal and transmit the fault signal to the microcontroller.Type: GrantFiled: February 18, 2020Date of Patent: May 24, 2022Assignee: Texas Instruments IncorporatedInventors: Indranil Gangopadhyay, Wan Laan Jackie Hui, Kyl Wayne Scott, Quanqing Hu, Ivo Francesco Marocco

Publication number: 20110169452Abstract: A battery cell tab monitoring apparatus includes a conductive element electrically connected between two battery cells. The conductive element is connected to a sensing circuit including a pull-down current source connected to pull current from the conductive element and/or a pull-up current source connected to drive current into the conductive element. A voltage measuring circuit is connected to sense voltages during operation of the pull-down current source and the pull-up current source to be used to determine the status of the conductive element. For instance, voltages beyond certain fixed or variable thresholds indicate that the conductive element is flexing or cracking, which can be a precursor to its breaking. Voltages beyond other fixed or variable thresholds indicate that the conductive element is fully disconnected. The current sources used to push and pull the sensing currents may be used to bring the battery cells into balance when an imbalance is detected.Type: ApplicationFiled: January 14, 2010Publication date: July 14, 2011Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: J.
