基于抗差UKF的动力锂电池SOC估计算法研究
Estimation of state of charge for Li-ion battery based on robust UKF
摘要
Abstract
A new state of Charge (SOC) estimation method of battery based on the robust-UKF was proposed to improve the energy management performance of the lithium-ion battery.Our main efforts are:firstly,the model of the lithium-ion battery was studied in detail to optimize the parameters; secondly,the simulation model of the battery SOC estimation system was established and the hardware experimental platform was designed; thirdly,the gross error of the measurement vector in other estimation method was focused.The characteristic of our new algorithm was that the traditional method OCV-Ah and the roubust-UKF estimation theory were combined and the main problem called the accumulated error could be solved effectively.The experimental results indicate that the new algorithm can improve the accuracy of the SOC estimation results for lithium-ion battery.Besides,the method is very important for the capacity improvement of lithium-ion battery pack,the efficiency improvement of the energy system and the product promotion.关键词
