Abstract
An apparatus for battery state of health (SOH) estimation, including: a DV-calculation unit () configured for calculating charge-derivative voltage dV/dQ according to operating parameters of a battery, and filtering the charge-derivative voltage dV/dQ; a feature detection unit () configured for performing a peak and threshold detection based on the filtered charge-derivative voltage dV/dQ to detect feature which fulfills requirements defined by a typical SOC range and height interval of a center graphite peak, and calculating an average temperature of the battery during a time interval corresponding to the detected feature; an estimation unit () configured for performing a SOH-estimate through a 2D-Look-Up-Table (2D-LUT) based on the detected feature and the average temperature.
