Abstract
An apparatus for battery state of charge (SOC) estimation, including: a pre-processing unit (), configured for detecting operating parameters of a batters, and filtering at least part of the parameters to generate filtered parameters; an SOC estimating unit (), configured for calculating nominal SOC by using a first neural network based on the operating parameters and the filtered parameters; a validity estimating unit (), configured for estimating a validity value based on the operating parameters and the filtered parameters, the validity value indicating validity of the nominal SOC outputted by the SOC estimating unit (); an SOC Kalman filter (), configured for performing a Kalman filtering algorithm based on the operating parameters, the nominal SOC transmitted and the validity value, thereby outputting an estimated SOC of the battery.
