Auxiliary Health diagnosis method for lead-acid battery
Applied Energy, 2010Co-Authors: Yu-hua Sun, Hurng-liahng JouAbstract:This paper proposes a Health Auxiliary diagnosis method for the lead-acid battery unit. The proposed method is based on Approximate Entropy (ApEn). Since ApEn can quantify the regularity of a data sequence and the discharging curve for a Health lead-acid battery unit is smooth, the proposed method can detect the degradation of battery unit caused by the internal short, opening of internal shorted or cell undergoing reversal using the distorted discharging curve. Aging experiments for the lead-acid battery are developed to verify the proposed method. The experimental results verify that the proposed Health Auxiliary diagnosis method can diagnosis the degradation of battery unit caused by the internal short, opening of internal shorted or cell undergoing reversal.

Auxiliary diagnosis method for lead acid battery Health based on sample entropy
Energy Conversion and Management, 2009Co-Authors: Yu-hua Sun, Hurng-liahng JouAbstract:Abstract In this paper, a Health Auxiliary diagnosis method based on Sample Entropy (SampEn) is proposed for the lead–acid battery unit. The concept of the proposed method is that the discharging curve for a Health battery unit is smooth; however, the degradation of battery unit caused by the internal shorts, opening of internal short or cell undergoing reversal will distort the discharging curve. Since SampEn can quantify the regularity of a data sequence, it can serve as an indicator for the state-of-Health (SOH) of the lead–acid battery. The salient feature of the proposed method is that SOH of the battery is estimated automatically at the end of each discharging cycle by measuring the battery voltage and current of a battery unit, so that no complicated measurement is required. To verify the proposed Health Auxiliary diagnosis method based on SampEn, aging experiments on lead–acid battery are developed. The experimental data shows that the proposed Health Auxiliary diagnosis method provides the expected results.
