Abstract
Disclosed is a method of predicting a remaining useful life (RUL) including measuring an operating current during a charging cycle and a discharging cycle of a battery, calculating a capacity fade of a plurality of cycles of the battery based on degradation parameters and the measured operating currents, and predicting an RUL of the battery based on the calculated capacity fade.
