Abstract
A device for detecting a battery condition may include a storage device storing a battery model that models a voltage change and an internal impedance of a battery as an electrical circuit, a measuring device configured to measure a current value of the battery, and a control device configured to estimate a distribution status of lithium ions within a positive electrode active material of the battery, detect a distortion zone remaining in a boundary portion of two identicalphase regions within the positive electrode active material based on the distribution status, estimate an overvoltage caused by the distortion zone, correct the battery model by using a correction parameter corresponding to the overvoltage, and determine a first state-of-charge (SOC) of the battery by using the battery model and an SOC estimated by integrating the current value.
