A completed charge is a charge that TeslaFi captures with at least one 'Complete' charging state data point.
Complete charges are also indicated on the individual charge summary with a checkmark and 'Charge Complete' note.
Only completed charges will appear in the battery report to insure that the range recorded is correct. Since the accuracy of the battery percentage is a whole number, without this complete data point, it is unknown if the charge completed at 79.1% or 79.9%.
