Summary: | Disclosed is a battery system (1) comprising: a battery module (10) connected between system terminals (T+, T-); a discharge circuit connected in parallel to the battery module (10) between the system terminals (T+, T-) and including a discharge switch (34) and a discharge resistor (35) connected to each other in series; a measuring unit arranged to measure voltage values of the battery module (10) and/or cells (100) included in the battery module (10) and/or current values which flow on the battery modules (10); a detecting unit arranged to determine whether or not an internal short occurs in the battery module (10) by monitoring the voltage values or the current values; anda control unit (23) arranged to control the discharge switch (34) so that the voltage value of the battery module (10) is dropped to a predetermined value or less when the internal short occurs in the battery module (10). |
