    Abstract: A monitor and control system and a method of monitoring and controlling an onboard system of an assembly includes one or more of a plurality of sensors detects whether an event occurred in the onboard system. The sensors communicate with a master controller when the master controller is in a nominal mode in which the master controller is powered on to actively monitor the sensors, and includes a sleep mode in which the master controller is powered off and does not monitor the sensors when in the sleep mode. An agent controller monitors the sensors when the master controller is in the sleep mode. One or more of the sensors signal the agent controller that the event has occurred. The agent controller signals the master controller to awaken from the sleep mode in response to the one or more of the sensors signaling the agent controller of the event.

    Abstract: An example method includes receiving, at a module management unit (MMU) associated with a battery cell, a battery cell parameter measurement associated with the battery cell. The MMU in is communication with a battery radio frequency module via a first link. The method further includes performing, by the MMU, a first function based at least in part on the battery cell parameter measurement to generate a first signal, and transmitting, from the MMU, the first signal to the battery radio frequency module via the first link. The method further includes performing, by the battery radio frequency module, a second function based at least in part on the first signal to generate a second signal. The method further includes transmitting, from the battery radio frequency module, the second signal to a controller, and performing, by the controller, a third function based at least in part on the second signal.

    Abstract: A battery module includes battery cells and a cell monitoring unit (CMU). The CMU includes a radio frequency (RF) communications circuit and a cell sense circuit connected to a substrate, the latter in wireless communication with the RF communications circuit. The cell sense circuit measures battery data, including a cell voltage and a cell temperature of each battery cell. The CMU includes a microprocessor in communication with the RF communications and cell sense circuits. The microprocessor determines when the battery module has been dormant for a predetermined dormancy duration during which the battery cells are neither charging nor discharging. Responsive to such dormancy, a Long-Term Data Storage Mode is executed in which the RF communications circuit paired with the cell sense circuit, collects the battery data at a calibrated interval, and wirelessly transmits the battery data to flash memory of the CMU for storage therein.

    Abstract: Systems and methods for diagnosing health of a battery using in-vehicle impedance analysis. The method includes receiving a sensed current measurement for a cell of the battery; generating a current profile as a function of the sensed current measurement, including pulses to a peak current, the pulses having a pulse frequency (w); applying a current with the current profile to the cell; for each pulse in the current profile, receiving a voltage measurement for the cell that is responsive to the pulse, calculating an impedance for the cell responsive thereto, the impedance comprising a real component at the pulse frequency (RZw), and an imaginary component at the pulse frequency (IZw), identifying a battery health problem when either RZw exceeds a preprogrammed first threshold for the pulse frequency, or when IZw exceeds a preprogrammed second threshold for the pulse frequency, and storing the RZw and the IZw for the cell.
