Roundtrip efficiency is a key performance metric for an system (ESS) that evaluates the energy losses incurred during a complete charging and discharging cycle. It is defined as the ratio of the energy output from the system during discharge to the energy input supplied during charging. A higher round-trip efficiency indicates lower energy losses and maximizes the usable energy stored in the system, which improves overall performance and red.
