RUL Prediction of Lithium-Ion Battery Based on Improved DGWO-ELM Method in a Random Discharge Rates Environment

Abstract: Lithium-ion batteries are widely applied in many fields. It is important for predicting battery life (RUL). It is randomly discharged that the lithium-ion battery under random conditions. The experiment of constant current discharge cannot simulate the discharge state under working conditions. Based on the data collection of the NASA dataset, the DGWO-ELM algorithm is proposed to predict lithium-ion battery. The DGWO-ELM is composed of Extreme Learning Machine (ELM), Grey Wolf Optimization (GWO), and Different… Show more

“…Consequently, different models are applied with various methods to predict the RUL to the most accurate level possible. Even though the aging level of a battery cannot be measured directly, the remaining battery life can be estimated, which can then be used to calculate the ageing level of battery [220]. As shown in Figure 10, RUL methodologies can be categorize into four classes: adaptive filter methods, intelligent methods, stochastic methods, and other methods [221].…”

“…Step 5: fitness is the objective function of optimization problem, and the calculation formula of fitness value is shown in equation (20), where fit is the fitness value and f i is the objective function value of the ith solution. In this paper, the objective function represents the mean square error (MSE) of SVR.…”
