Abstract:
A battery cell pass determination apparatus and a battery cell pass determination method involving verifying, after the battery cell is manufactured, whether the capacity of the battery cell repeatedly charged and discharged for a predetermined number of times satisfies a predetermined reference capacity, that is, determining whether a battery cell is a pass without having to charge and discharge a battery for 300 times, so that it is possible to quickly determine whether the battery cell is a pass.
