Abstract

The battery state of health (SOH) is a measure of the battery’s ability to store and deliver electrical energy. Typical SOH methods characterize either the battery power or energy. In this paper, new SOH estimation methods are investigated based on the battery energy represented by the Ampere-hour throughput (Ah). The methods utilize characteristics of the Ah to estimate the battery capacity or the useable energy for state of health estimation. Three new methods are presented and compared. The simulation results indicate the effectiveness of the methods for state of health estimation.
