Abstract
Lithium-ion batteries play critical roles in many electronicdevices. It is necessary to develop a reliable and accurateremaining useful life (RUL) prediction approach to providetimely maintenance or replacement of battery systems. Anovel RUL prediction approach based on Long Short-termMemory (LSTM) Recurrent Neural Network (RNN) isproposed in this paper. LSTM is able to capture long-termdependencies and model sequential data among the capacitydegradation of lithium-ion batteries. The advantages of ourproposed method include: 1) obtaining high predictionaccuracy without accurate physics-based model or expertiseand 2) decreasing the cumulation errors by multi-step aheadprediction each time, while traditional RUL method predictsone-step ahead once and then uses the current estimatedvalue to predict next one, which causes cumulation errorsincreased. The Center for Advanced Life Cycle Engineering(CALCE) battery datasets are used to demonstrate theeffectiveness of the proposed method. The results show that,compared with echo state networks (ESN), the proposedmethod has higher accuracy, more stable and reliableperformance for lithium-ion batteries RUL prediction.
