  • Patent number: 11460488
    Abstract: An electrical measurement device for monitoring the current and power taken by a plurality of electrical loads that may be powered by a selected one of multiple AC power sources comprises sampling the voltage of said sources and the current taken by said loads at a integral number of samples per cycle at sample times determined by an independent processor clock. The integral number of samples of each measured parameter for each cycle are processed to determine a complex number for each parameter representative of the amplitude and the phase relative to the independent processor clock. The phase drift of the substantially constant source voltages may be determined as a measure of frequency of the sources, and may be used to cancel drift of the current measurement to enable averaging.

  • Patent number: 11454674
    Abstract: If a charging quantity charged to a battery pack since switching from discharging to charging is more than or equal to a reference charging quantity, an ECU estimates the SOC from the OCV by referring to a charging OCV. If a discharging quantity discharged from the battery pack since switching from charging to discharging is more than or equal to a reference discharging quantity, the ECU estimates the SOC from the OCV by referring to a discharging OCV. If the electric quantity is less than the reference charging quantity or if the electric quantity is more than the reference discharging quantity, the ECU estimates the SOC from the OCV using a straight line for supplementing SOC-OCV characteristics in a region enclosed by the charging OCV and the discharging OCV.

  • Patent number: 11415630
    Abstract: In one aspect, an embodiment of this invention comprises an apparatus for updating an active fuel gauge of a battery cell. The apparatus comprises a memory, a sensor, and a processor. The memory stores data regarding an active fuel gauge of the battery cell based on a first voltage and state of charge (SOC) relationship. The processor receives first, second, and third resting voltage measurements at different times. The processor calculates differences in capacity between pairs of the resting voltage measurements based on the first voltage and state of charge (SOC) relationship. When the differences are equal the reference capacity difference, the processor identifies an estimate of a remaining capacity of the battery cell corresponding with the active fuel gauge. When the differences are not equal to the reference capacity difference, the processor updates the active fuel gauge based on an identified second voltage and SOC relationship.

  • Patent number: 11378474
    Abstract: This disclosure presents a dimensionless relationship between a fluid flow rate, a viscosity, and a brake horsepower (BHP) in a pump operation and a method that uses the dimensionless relationship to predict a BHP for viscous performance of a pump from water performance specifications. Using the dimensionless relationship, i.e., K-R number, the methods determine a BHP correlation that allows the prediction of the BHP specification to satisfy a pump performance metric at any given speed, flow rate, and viscosity. This prediction can be calculated from water performance specifications without physically testing the pump in the viscous implementation environment.
