Abstract

A battery system includes: a plurality of battery packs; a plurality of positive relays, each respective battery pack including a respective positive relay, connected between a positive electrode and a positive link of the respective battery pack; a plurality of negative relays, each respective battery pack including a respective negative relay, connected between a negative electrode and a negative link of the respective battery pack; and a plurality of pack BMSs (Battery Management Systems) connected to the plurality of battery packs in a one-to-one correspondence. Each pack BMS of the plurality of pack BMSs, in an opening control condition of the plurality of positive relays and the plurality of negative relays, may be configured to determine whether the positive relay of the pack BMS's corresponding battery pack is stuck-closed based on a first battery pack current flowing to the pack BMS's corresponding battery pack.
