The control unit determines an observation matrix including a plurality of observation voltage vectors indicating a voltage history of each of the plurality of battery cells in a moving window having a predetermined size based on the voltage signal. The control unit determines a recovery matrix including a plurality of recovery voltage vectors corresponding to the plurality of observation voltage vectors in a one-to-one relationship. The control unit detects an abnormality of each of the plurality of battery cells based on a plurality of absolute error vectors indicating a difference between the plurality of observation voltage vectors and the plurality of recovery voltage vectors.",
