摘要: Systems, devices, computer-implemented methods, and/or computer program products that can facilitate an intelligent battery cell are addressed. In one example, a device can comprise: active battery cell material; and an internal circuit coupled to the active battery cell material and comprising: a circuit board; two alternating current (AC) power points; two isolated direct current (DC) power points; and a controller that can operate one or more switches on an H-bridge circuit to disconnect the device from a main battery in a bypass mode. In another example, a smart cell modulator can comprise: a set of smart battery cells; and a controller that can operate to selectively engage a subset of the smart battery cells to enable load sharing, distributed feedback control, circulate load across one or more smart battery cells of the set of smart battery cells to increase torque, and to enable speed requests.

摘要: An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.

摘要: In a power supply system, a first system includes a first power supply connected to a first load. A second system includes a second power supply connected to a second load. A connection path connects the systems. An intersystem switch is provided on the connection path. A control apparatus sets the intersystem switch to a closed state and sets a voltage of the first power supply to be higher than a voltage of the second power supply to be a first state in which power supply is performed from the first power supply to the loads. In response to a reverse-direction current from the second system to the first system flowing to the connection path in the first state, the control apparatus sets the intersystem switch to an open state to be a second state in which power supply is performed from the second power supply to the second load.

摘要: A system and method for combining power from DC power sources. Each power source is coupled to a converter. Each converter converts input power to output power by monitoring and maintaining the input power at a maximum power point. Substantially all input power is converted to the output power, and the controlling is performed by allowing output voltage of the converter to vary. The converters are coupled in series. An inverter is connected in parallel with the series connection of the converters and inverts a DC input to the inverter from the converters into an AC output. The inverter maintains the voltage at the inverter input at a desirable voltage by varying the amount of the series current drawn from the converters. The series current and the output power of the converters, determine the output voltage at each converter.
