  • Patent number: 10693165
    Abstract: In one embodiment, an environmental sensor array monitors pre-filter airflow to a fuel cell with an air filter, and senses amounts of filter exposure of air contaminants in the monitored pre-filter airflow. The environmental sensor array may then correlate the sensed amounts of filter exposure over time to a long-term adsorption limit of the air contaminants for the air filter, determining a lifetime usage level of the air filter. Accordingly, the environmental sensor array may provide an indication of the lifetime usage level of the air filter. In another embodiment, the environmental sensor array may also monitor post-filter airflow to the fuel cell, and senses instantaneous levels of post-filter air contaminants. In response to the instantaneous level of any particular air contaminant of the post-filter air contaminants being above a respective threshold level, the environmental sensor array may protect the operation of the fuel cell (e.g., de-rate, shut down, etc.).

  • Patent number: 10693415
    Abstract: A method for testing a photovoltaic panel connected to an electronic module. The electronic module includes an input attached to the photovoltaic panel and a power output. The method activates a bypass to the electronic module. The bypass provides a low impedance path between the input and the output of the electronic module. A current is injected into the electronic module thereby compensating for the presence of the electronic module during the testing. The current may be previously determined by measuring a circuit parameter of the electronic module. The circuit parameter may be impedance, inductance, resistance or capacitance.

  • Patent number: 10693315
    Abstract: This invention is a DC-coupled, non grid-tied system comprising a solar panel, or an array of panels, a storage battery, a battery charger, an inverter, and optionally, a connection to an electric vehicle via both the regular AC charging connection and a DC connection. Unlike conventional grid-tied solar systems there is no possibility of solar or battery energy being fed back to the grid by virtue of the one-directional flow of energy through the battery chargers. The system can utilize all of the energy produced by the solar panels to provide power to critical household loads by storing electric energy in the storage battery. In the event of a grid outage, the system maintains power to the critical loads to the limits of the capacity of the batteries and the inverter, supplemented by whatever solar power is available. The energy available in an outage can be supplemented by using the main propulsion battery of an electric vehicle.

    Abstract: An energy storage system includes a photovoltaic energy field, a stationary energy storage device, an energy converter, and a controller. The photovoltaic energy field converts solar energy into electrical energy and charges the stationary energy storage device with the electrical energy. The energy converter converts the electrical energy stored in the stationary energy storage device into AC power at a discharge rate and supplies a campus with the AC power at the discharge rate. The controller generates a cost function of the energy consumption of the campus across a time horizon which relates a cost to operate the campus to the discharge rate of the AC power supplied by the stationary energy storage device. The controller applies constraints to the cost function, determines a minimizing solution to the cost function which satisfies the constraints, and controls the energy converter.

  • Patent number: 10461541
    Abstract: In a solar power generation control device, a memory stores an output voltage at which maximum power is obtained, for each illuminance on a panel surface of a solar panel, acquisition circuitry acquires a vehicle speed, a present illuminance on the panel surface, and first information indicating an illuminance in a prescribed area ahead of a vehicle, and calculation circuitry calculates a predicted illuminance on the panel surface, which is an illuminance after a lapse of a prescribed length of time, based on the first information and the vehicle speed. When determining that an absolute value of a difference between first and second output voltages, at which maximum powers are obtained respectively at the present and predicted illuminances, exceeds a prescribed threshold, control circuitry makes correction such that an output voltage of the solar panel coincides with the second output voltage upon the lapse of the prescribed length of time.

  • Patent number: 10459471
    Abstract: A collection, charging and distribution machine collects, charges and distributes portable electrical energy storage devices (e.g., batteries, super- or ultracapacitors). To charge, the machine employs electrical current from an external source, such as the electrical grid or an electrical service of an installation location. The machine determines a first number of devices to be rapidly charged, employing charge from a second number of devices identified to sacrifice charge. Thus, some devices may be concurrently charged via current from the electrical service and current from other devices, to achieve rapid charging of some subset of devices. The devices that sacrifice charge may later be charged. Such may ensure availability of devices for end users.

  • Patent number: 10459411
    Abstract: The present invention is directed to utility service delivery wherein distributed intelligence and networking is used in the optimization of the service delivery. The present invention employs a network of data collection nodes and aggregation nodes located on a power grid controlled by a controlling agency. The data collection nodes comprise Intelligent Communicating Devices (ICDs) and Communicating Devices (CDs), which transmit metrics they collect over the power grid from locations near meters or service transformers to the aggregation nodes. Commands, policies, and program updates may be transmitted from a server at an aggregation node to the ICDs and CDs. The ICDs are also capable of issuing control commands to the CDs and grid management devices, acting locally and/or in conjunction with other ICDs, CDs, aggregation nodes, and central controlling agencies. Through these communications and commands, utility services delivery and utilization is optimized.

  • Patent number: 10439428
    Abstract: This invention consists of an apparatus to interface an electric vehicle battery with a solar photovoltaic system and a method of using the apparatus to provide back up power during grid outages and ancillary service revenue from the grid. The apparatus uses the solar PV inverter to provide bidirectional power flow from the battery during night-time hours, or whenever the solar array is producing insufficient power. The apparatus thus consists only of switches and control and measurement equipment. It relies on the otherwise underutilized inverter and the on-board vehicle battery charger as the power electronic components, thus minimizing cost.
