  • Patent number: 10141776
    Abstract: Systems and methods for controlling power distribution are provided. The method includes receiving a power command, wherein the power command requests a discharge from one or more BESS units, and wherein the one or more BESS units are housed in one or more temperature controlled rooms. For each of the one or more temperature controlled rooms, a lowest energy remaining of the one or more BESS units in the temperature controlled room is determined; a low threshold is determined based on the determined lowest energy remaining and a floor; a limit is determined based on the determined low threshold; and the limit is assigned to each of the one or more BESS units housed in the temperature controlled room. The method includes causing the power command to be at least partially satisfied by the one or more BESS units based on the assigned limits.

  • Patent number: 9871396
    Abstract: Systems and methods for controlling the charge of an energy storage device include determining an estimated energy production prediction for an energy source from a present time to a target time by which an energy storage device is desired to reach a top of charge (TOC) energy level when being charged by the energy source. An available amount of energy for storage at the energy storage device if the energy storage device is charged from the energy source at a first charge rate from the present time until the target time is determined. A present charge rate for the energy storage device is controlled to be the first charge rate when the available amount of energy is less than the energy storage capacity of the energy storage device and to be a second charge rate less than the first charge rate when otherwise.

  • Patent number: 9657400
    Abstract: The present techniques provide a novel electrolyzer and methods for welding components of such electrolyzers. The techniques may use conductors, such as resistance wires, placed in paths around the internal structural features and edges of the components. The conductors may be incorporated into the components during manufacture by injection molding, or other molding techniques, or may be tacked or otherwise applied to the surface of the components after manufacture. When current, a field or other excitation is applied to the conductors, the plastic surrounding the wire is melted. If this plastic is in direct contact with an adjoining component, a strong, hermetic seal may be formed between the two components, including the internal structural features.

  • Patent number: 9080242
    Abstract: The present techniques provide systems and methods for mounting an electrolyzer stack in an outer shell so as to allow for differential thermal expansion of the electrolyzer stack and shell. Generally, an electrolyzer stack may be formed from a material with a high coefficient of thermal expansion, while the shell may be formed from a material having a lower coefficient of thermal expansion. The differences between the coefficients of thermal expansion may lead to damage to the electrolyzer stack as the shell may restrain the thermal expansion of the electrolyzer stack. To allow for the differences in thermal expansion, the electrolyzer stack may be mounted within the shell leaving a space between the electrolyzer stack and shell. The space between the electrolyzer stack and the shell may be filled with a non-conductive fluid to further equalize pressure inside and outside of the electrolyzer stack.

  • Patent number: 8277620
    Abstract: Embodiments of the present techniques provide electrolyzers made using thermoformed electrode assemblies and diaphragm assemblies. Each electrode assembly is made from two plastic rings and an electrode plate using a twin sheet thermoforming technique. A first plastic ring is laid in a mold having the appropriate shape to form the electrode assembly. The electrode plate is laid on top of the first plastic ring and is generally centered on the ring. The second plastic ring is laid over the electrode plate, and is generally centered over the electrode plate. The plastic is heated to soften the plastic, and a vacuum is pulled on the mold to pull the softened plastic into the shape of the mold. The mold is closed over the assembly to seal the two plastic rings together. After cooling, the molded part may be removed, resulting in a hollow plastic rim surrounding an electrode plate.

  • Patent number: 7989118
    Abstract: A method of manufacturing a fuel cell stack is provided. The method provides forming an inspectable preassembly of multiple fuel cell assemblies that may be termed a pseudostack. Each fuel cell in the pseudostack has permanent electrical interconnections and sealing connections on only one of the two electrodes, namely an anode layer or a cathode layer. For example, an anode interconnect may be firmly attached to the anode layer by means of a bonding agent and a sealing agent used to seal passages on the anode layer of the fuel cell. Alternatively, seals and permanent electrical connections may be made on the cathode layer of the fuel cell, and not on the anode layer.
