  • Patent number: 11955836
    Abstract: When a power outage occurs, an uninterruptable power supplies may lose all grid connections including a neutral connection which may be connected to ground. To avoid the loss of a ground connection to the power circuits of the UPS, a switch unit may be used to selectively connect a neutral conductor of the circuit to a ground terminal. The switch unit may comprise a power relay, a fast switch device (FSD), and a controller. The power relay and FSD may be connected in series between the neutral conductor of the circuit and a ground terminal. The controller may be configured to: close the FSD when the voltage between ground and neutral (Vng) goes above a first threshold, open the FSD when the voltage between any grid connection and neutral (Vg) goes above a second threshold, and close the FSD when Vg is below the second threshold.

  • Patent number: 11947402
    Abstract: UPS systems, methods, and computer-readable mediums utilizing electromechanical bypass relays to switch from an on-line mode of operation to a green/bypass mode of operation include control logic to adaptively adjust the timing of when an inverter of a UPS turns off to prevent backfeeding a utility. After the UPS is instructed to transition from the on-line mode to the green mode, a monitoring period begins. During the monitoring period, a parameter related to the output current of the inverter is monitored and compared to a predetermined threshold. If the parameter exceeds the predetermined threshold before a fixed period time has elapsed, the inverter is turned off early. If the inverter current does not exceed the predetermined value within the fixed period of time, the inverter is turned off.

  • Patent number: 11698398
    Abstract: Systems, methods, and devices are provided for controlling part of an electric power distribution system using an intelligent electronic device that may rely on communication from wireless electrical measurement devices. Wireless electrical measurement devices associated with different phases of power on an electric power distribution system may send wireless messages containing electrical measurements for respective phases to an intelligent electronic device. When wireless communication with one of the wireless electrical measurement devices becomes inconsistent or lost, the intelligent electronic device may synthesize the electrical measurements of the missing phase using electrical measurements of remaining phases. The intelligent electronic device may use the synthesized electrical measurements to control part of the electric power distribution system.

  • Patent number: 11691578
    Abstract: A vehicle control device includes: a power-supply control unit that sets a power supply to an off state when either a first power-off condition in which a user performs a power-off operation or a second power-off condition in which a first predetermined time elapses from the time when the user U gets off the vehicle with the power supply in an on state is satisfied; and a power-on-condition setting unit that: sets a power-on condition to a first power-on condition, when the power supply is set to the off state because the first power off condition is satisfied; and sets the power-on condition to a second power-on condition that is different from the first power-on condition, when the power supply is set to the off state because the second power off condition is satisfied.

    Abstract: An amount of power that is provided to a load is measured. The load is coupled to a battery backup unit (BBU) or an uninterruptable power supply (UPS). The amount of power is stored into a history of power draw for the load. The history of power draw is used to determine a time period or a situation when additional power is required by the load or reduced energy can be provided to the load. The charge of the BBU or the UPS is increased or reduced prior to the time period or the situation when the additional power is required by the load or the reduced energy can be provided to the load.
