1. A method for measuring and optimizing energy efficiency of a quantitative weighing device of a package charging system, said method comprising:
operating the package charging system over multiple packaging charging runs, including recording data from the quantitative weighing device over said multiple packaging charging runs, to form a data measurement part comprising:
a control time of fast charging (Ft),
a control time of slow charging (St),
a comparison prohibition time (Ht), and
weighing data (Wt);
calculating, at an electronic device associated with the package charging system, using the comparison prohibition time (Ht) and the control time of slow charging (St) and for each of the multiple measurements, feed times for charging a material at the quantitative weighing device, where a slow charging off weight threshold is ignored during the comparison prohibition time (Ht) for purposes of operating the show charging feed:
a control reliability parameter (Y) of the quantitative weighing device,
a fast charging feed flow (Cf), and
a slow charging feed flow (Cs);
calculating, at the electronic device associated with the package charging system, a fastest feed time of candidate combinations of the fast charging feed flow (Cf) for a first amount of time and the slow charging feed flow (Cs) for a second amount of time where the slow charging off weight threshold is ignored during the comparison prohibition time (Ht) and an absolute difference between a target reliability parameter and the calculated control reliability parameter (Y) under a predetermined threshold; and
as part of a further packaging charging run, charging the material at the package charging system, including by way of the quantitative weighing device, in accordance with a combination of the candidate combinations resulting in the fastest feed time.
