ABSTRACT:
A method (20or30) and system (40) for estimating a battery state of charge can include a memory (48) for storing at least one among an impedance value, a plurality of values for V drop0-1, or a plurality of values for V drop0-1normalized for charge or discharge values providing a stored plurality of values. The system can include a processor (44) and can measure at least one among V drop C-0providing a measured V drop C-0value and V drop0-1for the providing a measured V drop0-1value. The processor can be programmed to perform the functions of dividing the V drop C-0value by the impedance value to estimate a charging current at the battery or comparing the measured V drop0-1value with a value among the stored plurality of values to estimate the battery state of charge.
