摘要: This paper proposes a health auxiliary diagnosis method for the lead-acid battery unit. The proposed is based on Approximate Entropy (ApEn). Since ApEn can quantify regularity of data sequence and discharging curve unit smooth, detect degradation caused by internal short, opening shorted or cell undergoing reversal using distorted curve. Aging experiments are developed to verify method. experimental results that reversal.
