  "textContent": "A battery system includes: a plurality of battery packs; a plurality of positive relays connected between a positive electrode and a positive link of the corresponding battery pack for each of the plurality of packs; a plurality of negative relays connected between a negative electrode and a negative link of the corresponding battery pack for each of the plurality of packs; and a plurality of pack BMSs (Battery Management Systems) connected to the plurality of battery packs. Each of the plurality of pack BMSs, in an opening control condition of the plurality of positive relays and the plurality of negative relays, may diagnose whether the corresponding positive relay is stuck-closed based on the first battery pack current flowing to the corresponding battery pack when the corresponding negative relay is closed when a both terminals voltage difference of the corresponding positive relay is less than a first threshold voltage.",
