Abstract
Systems and methods for estimating the state of health (SOH) of a battery are provided. The system includes a database, a parameter processing module, and an SOH estimation module. The database stores current and voltage data measured at a specific sampling rate during battery charging. The parameter processing module obtains response functions in the frequency domain, differential capacity, and differential voltage based on the stored current and voltage data and uses them to obtain parameters for SOH estimation. The SOH estimation module uses some or all the obtained parameters to estimate the SOH.
