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.
Claims11
A method of predicting a remaining useful life (RUL), the method comprising:
- measuring an operating current during a charging cycle and a discharging cycle of a battery;
- calculating a capacity fade for 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 capacity fade.
An apparatus for predicting a remaining useful life (RUL) of a battery, the apparatus comprising:
- a predictor configured to measure an operating current during a charging cycle and a discharging cycle of a battery, to calculate a capacity fade of a plurality of cycles of the battery based on degradation parameters and the measured operating currents, and to predict an RUL of the battery based on the calculated capacity fade.
A non-transitory computer readable storage medium comprising a computer executable program code to cause a computer program to perform:
- 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 a remaining useful life (RUL) of the battery based on the calculated capacity fade.
