INTELLIGENT POWER MANAGEMENT SYSTEM AND METHOD FOR MONITORING BATTERY INTEGRITY

A battery monitoring system (BMS) for a battery of a battery electric system includes a sensor array, a processor, and memory. Execution of the instructions causes the processor to receive battery parameters from the sensor array during respective charging and discharging modes of the battery, including at least a voltage, current, and temperature of the battery. Separate charge-side and discharge-side resistances of the battery are determined during charging and discharging modes, followed by calculation of a degradation level of the battery using the charge-side and discharge-side resistances. The processor may also perform a preventive action in response to the degradation level exceeding a calibrated threshold.
