Abstract：The remaining useful life (RUL) of lithium-ion battery can evaluate the reliability of battery, which is an important parameter of battery health management. Accurate prediction of RUL of battery can effectively improve the safety of equipment and reduce the working risk. In this paper, a RUL prediction framework combined with the adaptive data preprocessing method and long-term and short-term memory neural network (LSTM) was proposed. Selecting capacity as the health factor, in the data preprocessing stage, the adaptive double exponential model smoothing method was used to reduce the negative effect of capacity recovery and the adaptive white noise integrated empirical mode decomposition (CEEMDAN) is used to suppress the noise. In the model constructing stage, the LSTM model was built for RUL prediction by training the preprocessed data. The NASA and CALCE open source data were selected to verify the performance of the proposed method. The experimental results show that it has good robustness and can provide RUL prediction results with high precision.
