Evaluation of batteries residual energy for battery pack recycling
A battery residual energy (remaining life detection) framework is proposed to provide a recycling strategy for spent batteries in EVs. Experiments are performed and AI
From both theoretical and practical aspects, the cells with average voltage in the battery pack are selected as representative cells and their residual energy is estimated as the residual energy of the battery pack at the current moment.
As these batteries reach the end of their life cycle, efficiently utilizing their residual value has become a key issue that needs to be resolved. This paper reviews the key issues in the cascade utilization process of retired lithium batteries at the present stage.
However, to maximize the residual value of these batteries before cascade utilization, it is necessary to estimate their residual capacity and perform consistency sorting. This paper primarily introduces the development status of residual capacity estimation and consistency sorting of retired lithium batteries.
For energy storage systems, the residual energy of the battery is the cumulative energy charged or discharged from the current moment until the battery reaches the charge/discharge cut-off voltage when the energy storage battery is charged or discharged at a certain operating condition.
