Abstract

Accurate state-of-health (SOH) monitoring of lithium-ion batteries plays an increasingly crucial role in the prognostic and health management (PHM) of batteries. Aiming at the shortcomings of the deep extreme learning machine (DELM) that the input weights and offsets are generated randomly and it is difficult to set parameters, a method combining intelligent search algorithm and DELM is proposed. First, we present a method based on improved symbolic regression algorithm to extract health indicators (HIs) from the discharging process curves of the batteries. Then, ISSA is proposed by combining the Tent mapping and dynamic weight factors to increase the search space of initial algorithm, and selfadaptive differential evolution strategy is used to jump out of the temporary optimal path. Finally, the optimized regression model is used to implement SOH monitoring. Compared with other data-driven methods, the method proposed in this paper can effectively reduce the error of SOH prediction.
