Abstract
A method and a system for estimating the State of Health (SOH) of a battery set are disclosed. The method utilizes a discrete quantization algorithm to estimate the SOH of the battery set, wherein the voltage standard deviations are calculated according to the loop voltages of the battery cells, and comparing the rated discharge capacity with the voltage standard deviations for estimating the SOH of the battery set.
