Abstract: A method of shaving peak power consumption by a facility includes determining a target peak demand setpoint for a facility and measuring power consumed by the facility. An electrical storage system (ESS) is charged when the measured power consumption is below the target peak demand setpoint. Additionally, the ESS is discharged and provides power to the facility when the measured power consumption is above the setpoint. Further, as data for the facility and ESS changes, the target peak demand setpoint is updated.

Abstract: According to an embodiment of the disclosure, a method for monitoring a battery pack is provided. The battery pack includes a plurality of modules and a pack controller, and each module includes a corresponding module controller. For each module, the method includes measuring a module current and measuring a module voltage. The measured module current and the measured module voltage are compared to state of health (SOH) data in at least one dynamic look-up table. A state of charge for the module is determined based on the comparison of the measured module current and the measured module voltage to the SOH data in the dynamic look-up table. For a particular embodiment, the dynamic look-up table is initially configured based on a type of battery chemistry for the battery pack, and after each charge cycle for the module, the dynamic look-up table is updated based on empirical data for the module.
