The biggest difference between them is in the distances they can travel without suffering major power losses. For example, AC can travel long distances without losing much power whereas DC electricity can''t travel so far but is much easier to store. Since AC is much better than DC for long-distance transmission, the power grid uses AC.
Round-trip efficiency is the ratio of energy charged to the battery to the energy discharged from the battery and is measured as a percentage. It can represent the battery system''s total AC-AC or DC-DC efficiency, including losses from self-discharge and other electrical losses.
