Abstract
The present invention relates to a battery system for detecting a damaged battery cell, and a method of evaluating a battery module. The battery system and the apparatus for evaluating performance of the battery module can accurately predict the location of the battery cell where gas has been generated by introducing a plurality of gas sensor units in the battery module where a plurality of battery cells are accommodated, and comparing gas detection time points measured in the gas sensor units when gas is generated in a battery cell. Hence, the battery system and the apparatus for evaluating performance of the battery module can be usefully used in terms of development of a battery module and/or management of a developed battery module.
