Accurate estimation of state of charge (SOC) and state of health (SOH) of lithium-ion batteries is of great significance in improving the performance of battery management system (BMS). In order to solve the problem that the unscented Kalman filter (UKF) algorithm has low accuracy in estimating the SOC of lithium-ion batteries, a double-multi-new information adaptive UKF (DMIAUKF) algorithm considering battery aging is proposed based on the UKF algorithm. The algorithm uses two multi-new information adaptive unscented Kalman filters (MIAUKF) to simultaneously estimate the SOC and SOH of the battery. Taking the ternary lithium-ion battery as the experimental research object, under the hybrid pulse power characteristic (HPPC) condition, the offline parameter identification method is used to identify the parameters of the second-order RC equivalent circuit model. The experimental results show that the DMIAUKF algorithm achieves high accuracy in estimating the SOC and SOH of lithium-ion batteries under constant-current discharge and HPPC conditions.
