Abstract
An exemplary method generally includes charging hydraulic fluid into or out of a cavity of an accumulator at a controlled flowrate, detecting movement of a machine component from a first position toward a second position, determining an idle time spanning from a start of the charging to detection of the movement of the machine component, and determining a pre-charge of the accumulator based upon the idle time and a flowrate value of the controlled flowrate.
