Echelon utilization occasions of power batteries at different capacity stages. Normal use stage: the battery capacity is 80–100%; that is, the power battery meets the use requirements of electric vehicles, and is used in the vehicle as a normal energy battery; The first stage of echelon utilization: the battery capacity is 60–80%.
For example, in 2020, the largest echelon energy storage power station in Zhejiang Province of China was officially put into operation. The total capacity of the energy storage station is 900 kWh, and the maximum output power can reach 300 kW. This project uses the retired LFP battery of a BYD E6 car.
