Abstract: Provided is a battery module and battery rack having enhanced fire safety features. The battery module includes a swelling/pressure sensor that detects swelling of a battery cell. An output signal of the sensor is used to halt operation of a battery rack/battery system containing the battery module and 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 suppression system that provides battery cooling in the event of a battery cell fire to prevent the spread and/or reigniting of the fire.

Abstract: The present invention provides a distributed energy storage system, and applications thereof. In an embodiment, the distributed energy storage system includes power units, wherein each power unit has a multi-cell battery; a battery manager that monitors battery cell voltages and temperatures; and a controller. The controller provides a first control signal that causes the power unit to store energy in the battery and a second control signal that causes the power unit to generate an alternating current. A server in communication with each of the power units stores data collected from the power units about the batteries and analyzes the data to determine how much available energy is stored in the batteries that can be used to alter a load demand of a power network, hi an embodiment, the batteries are lithium ion batteries capable of storing at least ten kilowatt- hours of energy.
