Abstract
A battery cell error determining apparatus including: a magnetic field measurement unit configured to measure a magnetic field generated by a current flowing in a battery cell, and a control unit configured to calculate a capacity of the battery cell by using a current calculated by the magnetic field measured by the magnetic field measurement unit. The control unit determines an error of the battery cell by using the capacity of the battery cell.
