摘要
以6节成组的航空锂电池组为检测对象,提出一种改进型无迹变换方法,通过精简三粒子和双重Sigma化处理过程,实现剩余电量估算值(SOC值)的有效迭代计算。仿真与实际测量的比较结果表明:该方法误差低于3.00%,有效提高了SOC值的估算精度。
Through taking the six-section aero-lithium battery pack as the object of detection,an improved untracked transformation method was proposed and the effective iterative calculation of SOC value was realized by simplifying the process of three-particle and double Sigma processing.Simulation and actual measurement results show that,the error of this method is less than 3.00%,which effectively improves the SOC estimation accuracy.
