Abstract: An energy storage module includes a module housing, a positive polarity module terminal and a negative polarity module terminal accessible via an external surface of the housing, and a plurality of battery cells contained within the housing and coupled in series between the positive polarity terminal and a negative polarity terminal to form a battery cell string. A removable manual service disconnect (MSD) unit is physically coupled to the external surface of the housing and electrically coupled between at least one battery cell in the battery cell string and one of the module terminals. The MSD unit has at least a first MSD operating state to allow current conduction between the positive polarity module terminal and the negative polarity module terminal, and a second MSD operating state to prevent current conduction between the positive polarity module terminal and the negative polarity module terminal.

Abstract: Systems and methods for controlling performance parameters for an energy storage device include providing primary control signals to an energy storage device that indicate at least one operating value in a range defined by at least one set point value for one or more performance parameters of the energy storage device. In one embodiment, an actual performance score for the energy storage device operated in accordance with the primary control signals is determined and compared with a required performance score to determine a performance score evaluation parameter. Additional control signals are then determined and provided to the energy storage device in a manner that adjusts the at least one operating value of the one or more primary control signals relative to the at least one set point value for the one or more performance parameters based at least in part on the performance score evaluation parameter.

Abstract: A control circuit for a power converter is provided. The control circuit includes a pulse width modulator, a current feedback loop, a bus voltage feedforward path, and a logic circuit. The pulse width modulator generates a control signal for the power converter to regulate a load current. The current feedback loop controls the pulse width modulator to converge the load current to a demanded current. The bus voltage feedforward path measures a bus voltage supplied to the power converter at an input bus and, in combination with the current feedback loop, control the pulse width modulator to regulate the load current based on the bus voltage. The logic circuit collects load current measurements and determines, based at least partially thereon, a voltage variation event has occurred on the input bus, and disables the control signal for the power converter in response to determining the voltage variation event has occurred.

Abstract: A reservoir includes power generation sources and energy storage systems. Some of the energy storage systems have a housing and energy storage devices. The energy storage systems are electrically connected to selected ones of the power generation sources. A system level combiner is in each of the energy storage systems, and the system level combiner combines power from the energy storage devices and selected ones of the power generation sources to provide system level combined power as a first output. A reservoir level combiner combines the system level combined power from a plurality of system level combiners into a reservoir level combined power. A power conditioning system receives, combines, and conditions the reservoir level combined power from the energy storage systems for supply to a power network. The energy storage devices are electrically connected to each other through the system level combiner and the reservoir level combiner.
