基于PSO-BP-UKF算法的锂电池SOC估计方法研究
Research on SOC Estimation of Lithium Battery Based on PSO-BP-UKF Algorithm
摘要
Abstract
The state of charge(SOC)of lithium batteries is one of the core of quality management of lithium batteries.Based on effective SOC estimation is also necessary to ensure the safe and efficient operation of lithium batteries,A method for estimating the SOC of lithium batteries is proposed,which uses particle swarm algorithm(PSO)to optimize the backpropagation(BP)neural network as the observed value of the unscented Kalman filter(UKF).The proposed PSO-BP-UKF algorithm is compared with the GA-BP-UKF algorithm and the BP algorithm using FUDS operating condition battery test data from the University of Maryland.Taking the test results in 25℃environment,the maximum deviation of PSO-BP-UKF algorithm is within 3.17%,the average error is within 6.44%,and the root-mean-square deviation is within 0.002 5,which is significantly improved than both GA-BP-UKF algorithm and BP method,and shows that the proposed algorithm is the effective and practical.关键词
