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.

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.
