The invention provides a battery module and a battery rack with enhanced fireproof safety characteristics. The battery module includes an expansion/pressure sensor that detects expansion of a battery cell. An output signal of the sensor is used to suspend operation of a battery rack/battery system containing the battery module and to prevent charging and discharging of the battery module. In an embodiment, the battery module uses an AC-to-AC power supply to provide AC frequency power for balancing battery cells of the battery module. In an embodiment, the battery rack includes an internal water fire extinguishing system that provides battery cooling in a battery cell fire event to prevent the fire from spreading and/or restriking.
