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%.
When capacity reaches less than 80%, decommissioned power batteries can be used in echelon, that is, in other energy storage fields or equipment with low requirements for battery capacity .
As for the industrial chain of echelon utilization of waste power batteries, the policy instruments are more concentrated in the downstream of the industrial chain. Central policies focus mainly on the stage of echelon utilization, with policy instruments accounting for 29.49% of the total industrial chain.
Retired power batteries should be tested and selected in order to meet the requirements of echelon utilization. Chen L proposed a new lithium-ion battery performance degradation model to predict its capacity decay, resistance increase and residual cycle life under various service modes [ 16 ].
Consequently, it is of vital importance for the CLSC to extend the horizon of application for echelon utilization of EV batteries. Establishing collaborative partnerships with entities in the energy sector represents a feasible strategy to maximize the utility of waste EV batteries.
