  • Publication number: 20200076014
    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.
