A method and an apparatus for battery modelling. The method includes acquiring battery information from a sensor attached to a battery, the battery information including at least a terminal voltage and a load current; classifying, the battery information as effective data or ineffective data based on a phase of a battery cycle during which the battery information is acquired; identifying one or more parameters of the circuit model associated with the battery based on the effective data; and generating an estimation of a state of the battery using the circuit model having the one or more parameters identified using the effective data. Further, a circuit model is identified using effective data.
