WANG Haiyang, SONG Wanqing. Prediction method for lithium-ion battery life using long-range dependence and chaos[J]. 2021, (7): 32-34. DOI: 10.13873/J.1000-9787(2021)07-0032-03.
A prediction method for remaining life of lithium battery based on fractional auto-regressive moving average(FARIMA) model combined with chaos theory is proposed.Firstly
before using model to predict
the maximum predictable time scale of the remaining life of lithium battery is given by calculating the Lyapunov exponent.Secondly
basic principle of FARIMA model is introduced and calculate the Hurst exponent H
the parameter for judging long-range dependence(LRD) of FARIMA.Then the definition
process and form of RUL prediction are given.Finally
model for capacity degradation data of lithium battery is selected as the prediction target
and the RUL prediction results are given by the FARIMA model.
