Battery rapid screening method and battery rapid screening system

An battery rapid screening method and a battery rapid screening system are provided. The battery rapid screening method includes the following steps: discharging a battery so that a state of charge of the battery after discharge is lower than or equal to a first preset ratio; measuring the battery by an electrochemical impedance spectrum analyzer to obtain an electrochemical impedance spectrum corresponding to the battery; performing an equivalent circuit simulation on the electrochemical impedance spectrum to obtain a plurality of impedance parameters of an equivalent circuit model; determining whether the battery is revivable according to a classification condition and the plurality of impedance parameters by a linear classifier.
