an RUL prediction method with complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and a genetic algorithms (GA) optimized bi-directional long and short-term memory (BILSTM) neural network is proposed. In this method
CEEMDAN decomposes the battery capacity data and also performs differential analysis on the battery data to obtain the feature inputs
and subsequently
the GA is used to optimize the hyperparameters of BILSTM to build the RUL prediction model of GA-BILSTM. Finally
validation is performed on the NASA dataset
and the results show that the method can realize RUL prediction accurately and effectively.
